Invention Patent Descriptive Report for "SENSOR SYSTEM AND METHOD FOR MONITORING A STRUCTURE". Technical Field
[001] The present invention relates, in general, to sensors and, more particularly, to an integrated sensor system for the detection, characterization, monitoring and analysis of data. Background
[002] In many vehicles, systems and / or other devices, sensors are used to track various performance, operational and / or status information. For example, some vehicles may include sensors for tracking fuel levels, temperature levels, outside temperatures, oil pressure values and / or other information. Other systems or devices can include numerous sensors for tracking information for various purposes.
[003] Civil and military aircraft often include a series of sensors to control various types of data from various sources. These sensors include, but are not limited to, engine thrust levels, engine temperature, altitude, position, speed, landing gear position, aileron position, location, orientation, others information, combinations thereof and so on. It is known that operational information associated with aircraft in general, and aircraft propulsion systems in particular, is important for pilots, flight crew, ground crews and airlines. As used herein, an aircraft "propulsion system" may include, but is not necessarily limited to, an engine, one or more input nacelles, one or more output nozzles, thrust reversers, supports and / or other associated structures and / or devices.
[004] An operating state, sometimes tracked by aircraft propulsion systems is a temperature of the propulsion system, which corresponds to a temperature of any part of the propulsion system including a part or the entire environment under the hood. In some aircraft propulsion system temperature monitoring systems, one or more thermal devices are positioned inside or close to one or more components of a propulsion system. A temperature detected by the thermal device is tracked and compared to a defined limit. If the detected temperature exceeds the limit, an alarm or warning can be reported to a flight crew or a ground crew. Some common thermal devices used in aircraft propulsion systems are linear devices that can measure between two to more than 20 feet in length. As such, the hot spots along the length of the thermal devices can be calculated by other areas of the propulsion system.
[005] However, these thermal devices have limitations. In particular, some overheating or fire conditions may be lost due to the average temperature across the thermal sensors. In addition, finding high heat, overheating or fire conditions can be difficult since the devices provide only a measurement for what can be a large area of the structure or the monitored device. Thus, troubleshooting of systems or other propulsion structures after the occurrence of an alarm condition or state may require disassembly of the monitored device and / or speculation to determine a condition that led to the alarm or other actionable operating state . In addition, current technologies do not allow any possibility to adjust the alarm trigger points to take into account changes in operating conditions, such as the external environment or operational demands on the monitored system.
[006] It is with respect to these and other considerations that the presentation made here is described. summary
[007] It should be noted that this summary is provided to introduce a selection of concepts in a simplified form which are further described below in the detailed description. This summary is not intended to be used to limit the scope of the claimed matter.

[0062] The detailed description refers to an integrated sensor system for the detection, characterization, monitoring and analysis of data. According to the concepts and technologies presented here, a monitoring system communicates with an integrated sensor system that can include numerous sensors for monitoring a structure or environment, such as an aircraft engine, a propulsion system , the entire environment under the hood, or other system, device, structure, or environment. The sensors can generate the data and transmit, or make the data available to the monitoring system. The monitoring system can run one or more application programs to monitor the data generated by the sensors to determine whether the structure is operating normally or abnormally. The monitoring system can also store the limit values that define the alarm conditions, as well as the expected values that define various expected values in certain operational states, such as ambient temperatures, pressure levels, flight phases, altitudes, and the like. The limit values can be stored as a set of individual limit values adapted to each sensor in the sensor system.
[0063] According to some implementations, the monitoring system is configured to use the operational data and other data obtained by various systems to adjust the data obtained by the sensors. The monitoring system can generate the adjusted data values that adjust the current data obtained by the sensors according to the expected differences based on ambient temperatures, pressure levels, and the like. These adjusted data values can be compared to the limit to determine whether the monitored structure is operating normally or abnormally. In other modalities, the monitoring system adjusts the limits to obtain the adjusted limits and compares the adjusted limits to the data obtained by the sensors.
[0064] If the monitoring system determines that the monitored structure is not operating normally, the monitoring system can invoke the reporting functionality to report an alarm to one or more entities. The monitoring system can also store the data obtained from the sensors for further analysis and / or troubleshooting. Thus, analysts have access to the current readings of the sensor, so that detailed analysis can be performed without counting the general alarm status and / or inaccurate location information, since the sensors can have the locations defined within the monitored structure. Analysts can also look at historical data for countless flights, to look for trends that have not yet reached the state of alarm, but can indicate an impending failure that could then be prevented rather than repaired. This can allow for planned maintenance planning and / or help provide efficient fleet management. Thus, the modalities of the concepts and technologies presented here may allow for a more detailed and easier solution of problems than would be possible with existing monitoring devices and / or sensor systems. These and other advantages and characteristics of the concepts and technologies presented here will be evident from the description of several modalities below.
[0065] In the detailed description below, references are made to the attached drawings that form part of this and that show, by way of example, the specific modalities or examples. In reference to the drawings, the same numbers represent the same elements throughout the various figures.
[0066] Now, with reference to figure 1, the aspects of an operating environment 100 for the various modalities presented here will be described. The operating environment 100 shown in figure 1 corresponds, in various modalities, to an aircraft or other vehicle, although the operating environment 100 can be realized in other devices or systems. In the illustrated embodiment, the operating environment 100 includes a monitoring system 102. In some embodiments, the monitoring system 102 operates on or in communication with a network 104, although this is not necessarily the case. The functionality of network 104 can be provided by one or more communication links, by one or more vehicle networks, by one or more wireless or wired communications, by one or more communication networks, and / or by other systems, connections and / or devices.
[0067] According to various modalities, the functionality of the monitoring system 102 is provided by a control system implemented as an on-board computer, an aircraft avionics system, and / or other computing devices or systems. The monitoring system 102 functionality can also be provided by a personal computer ("PC"), such as a desktop, tablet or laptop computer system; a server computer, a portable computer and / or other computing device. Thus, although the functionality of the monitoring system 102 is described in the present invention as being associated with or provided by an aircraft avionics system, it should be understood that this modality is illustrative, and should not be considered as limiting in any way.
[0068] According to various modalities, the monitoring system 102 is configured to run an operating system (not shown) and one or more application programs such as, for example, a monitoring application 106, an alarm emission application and report ("reporting application") 108, and / or other application programs. The operating system is a computer program for controlling the operation of the monitoring system 102. Application programs are programs that can be run configured to run on top of the operating system to provide the functionality described here for monitoring, detection and the analysis of data obtained from one or more sensors, for the issuance of reports and / or the recording of information tracked or determined by the monitoring system 102, and / or for the generation of alarms and alerts for various entities.
[0069] According to various modalities of the concepts and technologies presented here, the monitoring system 102 communicates with and / or monitors one or more systems, for example, an engine 110. In an observed modality, the monitoring system 102 communicates with and monitors one or more aircraft engines. Due to the fact that the monitoring system 102 can monitor several systems or devices in addition to, or instead of, the illustrated engine 110, it should be understood that this modality is illustrative, and should not be considered as limiting in any way.
[0070] Engine 110 may include, may approach, may communicate with, and / or may be coupled to an integrated sensor system 112. The integrated sensor system 112 is configured to generate data 114 that indicate or that represent one or more operating states or conditions of motor 110. For example, the integrated sensor system 112 can correspond to one or more temperature sensors (not shown in figure 1) located on motor 110. Thus, the data 114 generated by the system of integrated sensor 112 can correspond to one or more temperature measurements obtained by the integrated sensor system 112. Some observed modalities of motors 110, sensors used to provide the functionality associated with the integrated sensor system 112, and / or several illustrative modalities of the system of integrated sensor 112 are illustrated in more detail below with reference to figures 2 to 7. Due to the fact that the integrated sensor system 112 can be realized inside out structures and / or types of structures, it should be understood that the modalities illustrated are illustrative, and should not be considered as limiting in any way.
[0071] Monitoring application 106 is configured to obtain data 114 from the integrated sensor system 112 and to analyze data 114 to determine an operating state or condition associated with engine 110. The determined operating state or condition can be used to determine whether engine 110 is operating normally or abnormally. Monitoring application 106 can make this determination based on various data 114. For example, data 114 obtained by monitoring application 106 may include operational and / or environmental data associated with the monitored structure or system in addition to data obtained or generated by integrated sensor system 112. As noted above, monitoring system 102 is implemented, in some cases, inside an aircraft. Therefore, operational and / or environmental data may include various data associated with the aircraft, such as data indicating a current flight phase, data indicating a pressure setting associated with one or more aircraft aircraft engines. , the operational or historical performance data associated with the aircraft and / or the aircraft systems or components, the data that indicate an outside air temperature and / or other environmental conditions, combinations thereof and the like. This data 114 can be obtained and analyzed by the monitoring application 106 in addition, or instead of the data obtained by the integrated sensor system 112.
[0072] The monitoring application 106 can be configured to compare the data obtained 114 with one or more values of known, expected and / or historical operational data ("the operational data") 116. Operational data 116 may include, among others data, alarm limit data ("limits") 118 to trigger the alarm, warning or alert conditions on the aircraft. Limits 118 can be defined as absolute values. For example, a 118 temperature limit can be set to 426.67 ° C (800 ° F) or any other temperature. Limits 118 can also be defined as deviations from normal or accepted values. For example, a 118 pressure limit can be defined as an increase of 0.14 MPA (20 psi) per second. It should be understood that these examples are illustrative and should not be considered as limiting in any way. In particular, any suitable values, rates or ranges can be defined and stored as limits 118.
[0073] Operational data 116 may also include expected values 120. Expected values 120 may correspond to the measurements or sensor readings expected to be observed in various operational states, environmental conditions, locations, orientations, flight phases and / or based on other conditions in the monitored structure or system. For example, expected values 120 may include the expected temperature or pressure values to exist at a specific pressure level, ambient temperature, flight phase, altitude, and / or under conditions associated with an aircraft. The expected values 120 can be obtained from flight test and analysis data, manufacturer information and / or other sources of information.
[0074] The expected values 120 can be used by the monitoring application 106 to adjust the limits 118. In particular, the monitoring application 106 can be configured to modify the limits 118 based on data 114. Thus, the monitoring application 106 can create the adjusted limit values ("the adjusted limits") 118 'which is based on the 118 limits, but which also take into account environmental or operational information that may affect the conditions observed in the integrated sensor system 112. As will be explained in more detail here, monitoring application 106 can also be configured to adjust the data 114 obtained from the integrated sensor system 112 to obtain the adjusted data values 114 '(also called "adjusted data values" here) , and to compare the data values adjusted 114 'to the limits 118 instead of or in addition to adjusting the limits 118. In other embodiments, the monitoring application 106 is configured to compare the data 114 obtained by the integrated sensor system 112 to the adjusted limits 118 'to determine whether a propulsion system is operating normally or abnormally.
[0075] Thus, various modalities of the monitoring system 102 presented here are configured not only to monitor and analyze data 114 and / or to compare data 114 with basic alarm limits, such as limits 118, but also to host other data to generate the adjusted limits 118 ', and compare the data 114 with the adjusted limits 118'. Thus, several modalities of the concepts and technologies presented here provide the emission of alarms and / or alerts more precisely than would be possible just by comparing the data 114 to the basic alarm limits 118. The monitoring application 106 is configured to invoke or triggering the reporting application 108 to report or save data 114 for various purposes. In some embodiments, for example, monitoring application 106 invokes or triggers reporting application 108 if monitoring application 106 determines that engine 110 is not operating normally, or if monitoring application 106 determines that a alarm, alert, or warning status exists on engine 110. In other embodiments, reporting application 108 reported and / or records data 114 even if alarm, alert, or warning states do not exist on engine 110.
[0076] The reporting application 108 can be configured to provide a functionality described here for the generation or detection of alarms, alerts, or warnings; for issuing reports of alarms, alerts, or notices; for recording data 114 if alarms, alerts, or warnings are detected, for recording data 114 even if alarms, alerts, or warnings are not detected; and / or to provide other functionality presented here. For the purpose of simplifying the presentation, the description refers to the alarm states and conditions, although it must be understood that the warning states or other states associated with the abnormal operation can be detected, reported and / or can trigger the storage of data 114 and / or the adjusted data value 114 '.
[0077] As noted above, the functionality of the reporting application 108 can be invoked or triggered by the monitoring application 106, although this is not necessarily the case. It should be understood that the functionality of the monitoring application 106 and the reporting application 108 can be provided for less than or more than two application programs, if desired. Similarly, although the monitoring application 106 and the reporting application 108 are illustrated here as separate entities, this modality is illustrative and is described to simplify the description of the concepts and technologies presented here. Thus, the illustrated modality should be understood as being illustrative, and should not be considered as limiting in any way.
[0078] If the reporting application 108 determines or is informed that an alarm state exists in the motor 110, the reporting application 108 can generate an alarm 122. The reporting application 108 can transmit the alarm 122 to an alarm container 124. According to the various implementations, alarm container 124 includes, but is not limited to, a visual indicator such as a light, a meter, or other device; an audible indicator, such as a siren, alarm, or other audible device; one or more other systems to alert staff or flight systems of the alarm state; combinations thereof, and the like. Reporting application 108 can also transmit alarm 122 to a remote alarm system, such as a ground crew, a control tower, a remote monitoring device, other systems, devices, or entities, combinations thereof , and the like. Due to the fact that alarm 122 can be transmitted or provided to any suitable alarm container 124, it should be understood that the examples provided above are illustrative, and should not be considered as limiting in any way.
[0079] Reporting application 108 can also be configured to record data 114 on a data storage device 126. Data 114 can be stored for various purposes. For example, data 114 can be stored on data storage device 126 and retrieved for detailed analysis and / or for other purposes, by any authorized personnel. Thus, one or more entities can perform the analysis of a state or states that triggered alarm 122, or of raw data 114 for maintenance planning, operational prognosis or other diagnostic purposes. Due to the fact that data 114 can be stored for any purpose, the above example should not be construed as limiting in any way.
[0080] According to various modalities, the functionality of the data storage device 126 is provided in one or more databases, server computers, desktop computers, mobile phones, laptop computers, other computing systems, and the like. The functionality of the data storage device 126 may also be provided by one or more virtual machines and / or otherwise hosted by a cloud computing environment, if desired. In other embodiments, the functionality of the data storage device 126 is provided by one or more data storage devices associated with the monitoring system 102, for example, a memory, a mass storage device, a storage medium that can be read by computer as defined here, combinations thereof, and the like. In the described embodiments, data storage device 126 is called a local storage device located at or near monitoring system 102. For example, data storage device 126 may be a memory device associated with the monitoring system. - monitoring 102. It should be understood that this modality is illustrative, and should not be considered as limiting in any way.
[0081] Figure 1 illustrates a monitoring system 102, a network 104, a motor 110, an alarm container 124, and a data storage device 126. It should be understood, however, that some implementations of the Operation 100 includes or omits multiple monitoring systems 102, multiple networks 104, multiple motors 110, multiple alarm containers 124, and / or multiple data storage devices 126. Thus, the illustrated modalities should be understood as illustrative, and not should be considered as limiting in any way.
[0082] Now, with reference to figure 2, an integrated sensor system 112 is shown, according to an illustrative modality. In figure 2, the integrated sensor system 112 is shown as including any number of sensors 200A-N (hereinafter collectively and / or in general referred to as sensors 200). It should be understood that the integrated sensor system 112 can include any number of sensors 200. In addition, sensors 200 can be grouped physically or logically, if desired, although this is not necessarily the case. Some illustrative embodiments of sensors 200 are illustrated and described below with reference to figures 4A-6.
[0083] The integrated sensor system 112 can be integrated, coupled and / or in communication with the monitored structure (not shown). As noted above, the monitored structure can include a vehicle, a system, a device, and / or various components thereof. As shown in figure 2, each of the sensors 200, or the sensor combinations 200, can generate the data 114.
[0084] According to various modalities, the data 114 generated by the sensors 200 is reported or supplied to the monitoring system 102 in a batch or compiled format and / or as flows, measurements or independent data packages. More particularly, in some implementations, sensors 200 report data 114 independently to monitoring system 102 without averaging, dosing, compiling and / or other means of gathering or relocating measured data 114. For example, if ten sensors 200 are included in the integrated sensor system 112, sensors 200 can provide made flows, packages or measurements of data 114, and data 114 generated through the respective sensors 200 can be provided to monitoring system 102. For example, if nine of the ten sensors 200 obtain the measurements of one hundred degrees and one of the ten sensors 200 obtain a measurement of one thousand degrees, these ten values can be supplied to the monitoring system 102 as data 114. Thus, the monitoring system 102 can detect and can act on the measurement of a thousand degrees, which can correspond to a fire condition or another condition that should trigger a condition or alarm state.
[0085] In some modalities (not shown), however, data 114 generated by sensors 200 is grouped in batches and reported as an average or compiled value. In the example above, data 114 can be grouped or compiled and monitoring system 102 can therefore determine the average temperature by sensors 200 as 190 degrees, which corresponds to an average of ten sensors 200. As noted above, the monitoring system therefore, it may or may not detect the 1000 degree reading. Although several benefits can be realized by some modalities of the concepts and technologies presented here for not grouping data 114, some modalities can, however, compile or group data 114 for other purposes. Thus, the illustrated modalities should be understood as illustrative, and should not be construed as limiting in any way.
[0086] In the modalities described here, sensors 200 are configured independently and / or individually to report data 114 to the monitoring system 102. In other modalities, the integrated sensor system 112 reports data 114 to the monitoring system monitoring 102. Thus, monitoring system 102 can receive data 114 obtained by sensor 200A, for example, and not just the compiled data file associated with sensors 200. It must be understood that this modality is illustrative, and should not be considered as limiting in any way.
[0087] Now, with reference to figure 3, an implementation of the integrated sensor system 112 is shown, according to an illustrative modality. In Figure 3, sensors 200 are shown arranged in, in, or within an aircraft propulsion package, which consists of an engine, aerodynamic hood (nacelle) and mounting bracket ("aircraft propulsion system") 300. Although not visible in figure 3, it should be understood that a density with which sensors 200 are distributed along and / or around aircraft propulsion system 300 can be varied. In particular, a relatively high density of sensors 200 can be positioned in areas where relatively high temperatures are expected to provide a high resolution measurement capability. Similarly, a relatively low density of sensors 200 can be positioned in areas where relatively lower temperatures are expected. In some embodiments, an area where relatively high temperatures are expected includes the turbine compartment of the aircraft propulsion system 300, and an area where relatively low temperatures are expected include the fan compartment of the aircraft propulsion system 300. It should - understand that this modality is illustrative, and should not be considered as limiting in any way.
[0088] As noted above, the integrated sensor system 112 and / or sensors 200 can be realized in other devices, environments or structures instead, or in addition to the aircraft propulsion system 300. Thus, the illustrated modality must be understood as illustrative and should not be construed as limiting in any way. Due to the fact that aircraft structures are generally understood in the art, the various structures of the illustrated aircraft propulsion system 300 are not described here in the additional details.
[0089] The sensors 200 can be arranged adjacent, close and / or integrated within various structures of the aircraft propulsion system 300. For example, the sensors 200 can be built into the walls of the aircraft propulsion system 300, arranged in several points within the aircraft propulsion system 300 as at or near entrances, at or near nozzles and / or other locations that can be determined by the team that designs, performs maintenance, and / or builds the aircraft propulsion system 300 , by the team that perfects the aircraft propulsion system 300 with the capabilities described here in relation to the integrated sensor system 112 and / or the monitoring system 102, and / or by any other entities. Thus, the illustrated locations of sensors 200 should be understood as illustrative, and should not be construed as limiting in any way.
[0090] Sensors 200 may include any suitable sensor devices and / or combinations of sensor devices. For example, in some embodiments, sensors 200 include one or more photosensors, optical sensors, thermal sensors, pressure sensors and / or combinations thereof. Various illustrative modalities for sensors 200 are demonstrated and described in detail below with reference to figures 4A-6B. Due to the fact that any suitable sensors 200 can be used in various modalities of the concepts and technologies presented here, the various modalities of sensors 200 provided herein should be understood as illustrative, and should not be considered as limiting in any way.
[0091] Now, with reference to figure 4A, the additional aspects of sensors 200 are shown in detail, according to an illustrative modality. In particular, Figure 4A is a line diagram illustrating aspects of a sensor 200 'according to an illustrative embodiment. The sensor 200 'shown in figure 4A is configured for use in temperature measurement, although this modality is illustrative. The sensor 200 'includes a substrate 400. The substrate 400 may include a motor component, an independent carrier tape or other substrate, or any other structure suitable for carrying a thermocouple 402 or other element. In the illustrated embodiment, substrate 400 is supplied by titanium bead. It must be understood that this modality is illustrative, and should not be considered as limiting in any way.
[0092] Thermocouple 402 may, as is known, include a combination of materials to measure a voltage generated by heat in or around thermocouple 402. Thermocouple 402 may include, but is not limited to, a first trace 404 formed from from a first material and a second trail 406 formed from a second material. The first track 404 and the second track 406 can meet or be arranged close to each other to facilitate electron transfer between the first and the second material. More particularly, as is known, heat can cause an electron transfer from the first material to the second material, and the resulting voltage can be measured to determine a temperature at or near thermocouple 402.
[0093] Thermocouple 402 may be sprayed, printed or otherwise deposited on substrate 400 by any suitable process including, for example, using plasma flame spray, atomized sand deposition, screen printing, ink blasting , and / or other processes. In some embodiments, the first track 404 and the second track 406 form a joint. In the illustrated embodiment, a dielectric trail 408 is provided to separate the electrically conductive thermocouple tracks 404 and 406 from the electrically conductive substrate 400. In some embodiments, the separation of the electrically conductive thermocouple tracks 404, 406 from the electrically conductive substrate 400 can help prevent an electrical short circuit between these elements. In some embodiments, the dielectric trail 408 can be omitted, for example, if substrate 400 is not electrically conductive.
[0094] The 408 dielectric trail can be formed from a ceramic material, such as spinel or other suitable material, although this modality is illustrative and should not be construed as limiting in any way. Similarly, in the illustrated embodiment, the first feature 404 and / or the second feature 406 are configured as type N thermocouples, although this feature is illustrative. Although not shown in figure 4A, it should be understood that thermocouple 402 may include additional tracks or paths to one or more interface connectors for redundancy, as shown in more detail in figure 4B.
[0095] In some embodiments, thermocouple 402 is printed on or otherwise located on a hot side of a motor component or other structure. For example, thermocouple 402 can be printed on an internal part of the surface of an aircraft engine before, during, or after the assembly of the aircraft engine. In one implementation, thermocouple 402 is printed on an internal part of the surface of a honeycomb face sheet of an aircraft engine composite. It must be understood that these modalities are illustrative, and should not be considered as limiting in any way.
[0096] In some embodiments, thermocouple 402 is printed on or otherwise located on a cold side of an engine. For example, thermocouple 402 can be printed on an outer surface of a motor component. If thermocouple 402 is arranged on an external or cold side of an engine, the temperature measured by thermocouple 402 can be used to estimate the temperature on a hot side or inside the component using one or more formulas or mathematical algorithms. In one embodiment, thermocouple 402 is printed on an outer surface of a honeycomb face sheet, and a mathematical algorithm is used to estimate a temperature on the hot side of the component. It must be understood that this modality is illustrative, and should not be considered as limiting in any way.
[0097] In some modalities, an anemometer or other device can also be printed on a cold side of the engine or another component to further compensate for the convective heat transfer on the cold side of the component. Thus, it can be seen that a thermocouple 402 as shown here can be printed or located on a hot side or a cold side of the engine or component and / or that various structures and / or devices can be used to determine or estimate temperatures on the motor or other component based on data obtained from or thermocouple 402. Due to the fact that thermocouple 402 can be replaced by other types of circuitry or sensors, and due to the fact that thermocouple 402 can be used in other structures, it should be understood that the various modalities discussed above are illustrative, and should not be considered as limiting in any way.
[0098] Figure 4B is a circuit diagram that illustrates the additional aspects of sensor 200 'shown in figure 4A. As shown in figure 4B, sensor 200 'can include a substrate 400, which can include various materials and / or structures as explained above with reference to figure 4A. The sensor 200 'may also include one or more connectors 410A-B (hereinafter collectively and / or generally referred to as "connectors 410" hereinafter). The sensor 200 'can be connected, can communicate with, and / or can be coupled to any number of devices, for example, the monitoring system 102, through the connectors 410.
[0099] The sensor 200 'includes, in the illustrated modality, six thermocouple junctions 412 and two dielectric patches 414A-B (hereinafter collectively and / or generally called "dielectric patches 414"). It should be understood that if substrate 400 is conductive, the dielectric strips can be included under any traces and / or between the strokes instead, or in addition to the illustrated dielectric patches 414. As shown in figure 4B, a first trace 416 formed at from a first thermocouple material it can be in contact with a second track 418 formed from a second thermocouple material at one of the junctions 412. Dielectric patches 414 can be provided to isolate tracks 416, 418 and / or other equivalent tracks or redundant from each other in locations other than junctions 412, if desired. As mentioned above, if substrate 400 is conductive, a dielectric track or dielectric layer can be arranged between tracks 416, 418 and substrate 400 in addition to dielectric patches 414. In the illustrated embodiment, a track 416 and six tracks 418 are included plus six junctions412 to provide the 200 'sensor with redundancy. This arrangement allows multiple thermocouple junctions 412 to be read on both connectors 414 while also allowing their respective tracks to be, in general, widely spaced to protect physical threats to the tracks. Although the illustrated sensor 200 'includes six thermocouple junctions 412, a track 416 and six tracks 418, it should be understood that this modality is illustrative, and should not be considered as limiting in any way.
[00100] Now, with reference to figure 5A, the additional aspects of sensors 200 are shown in detail, according to an illustrative modality. In particular, figure 5A is a line diagram that illustrates the aspects of a 200 "sensor, according to another illustrative modality. The 200" sensor shown in figure 5A is configured for use in temperature measurement, although this modality is illustrative. . The sensor 200 "includes a substrate 500. The substrate 500 may include a motor component, an independent carrier tape or other substrate, or any other structure suitable for the transport of one or more 502A-C thermocouples (hereinafter document generally or collectively called "thermocouples 502"). Substrate 500 may be formed from a suitable material that includes, but is not limited to, metals, polymers, and / or other materials.
[00101] In the illustrated embodiment, the substrate 500 is provided by a flexible material that allows the flexion and / or the embedded shape of the 200 "sensor. Thus, the 200" sensor can be fixed or curved or formed irregularly to the surfaces and / or located in or in several structures. According to various modalities, the substrate 500 can be mechanically fixed to a structure using any suitable fastening method including, but not limited to, adhesive bonding, metallic or bronze welding, plastic welding, welding ultrasonic, laser welding, mechanical closures, and / or other suitable processes and / or devices.
[00102] Each of the 502 thermocouples or other devices can be printed on the flexible substrates and arranged in a stacked relationship, as shown in figure 5A. It is observed that when substrates 500 are electrically conductive, thermocouples 502 can be electrically isolated from the substrate by depositing a dielectric material, not shown, like a spinel between thermocouples 502 and substrates 500. Thus, the sensor 200 " can include numerous substrates 500, although this is not necessarily the case. Several implementations of the 200 "sensor are illustrated and described in more detail below, particularly with reference to figures 5C-5E. The sensor 200 "can include one or more thermocouples 502 and / or a combination of several sensors or devices, if desired. Thus, the sensor 200" can include multiple devices to provide redundancy and / or to provide various combinations of functionality. It must be understood that this modality is illustrative, and should not be considered as limiting in any way.
[00103] Figure 5B is a circuit diagram illustrating the additional aspects of the sensor 200 "shown in figure 5A, according to one embodiment. As shown, a sensor 200" can include a substrate 500, which can include a flexible material or inflexible, if desired. The 200 "sensor can include one or more 510A-B connectors (hereinafter collectively and / or generally referred to as" 510 connectors "hereinafter). The 200" sensor can be connected to one or more devices such as, for example , the monitoring system 102, through one or more connectors 510.
[00104] The sensor 200 "may include, as is known, the circuitry corresponding to one or more thermocouples 502, as discussed above. Thermocouples 502 may include a combination of materials to measure the voltage generated by the heat in or at the around thermocouple 502. For example, thermocouple 502 can include numerous thermocouple junctions 512. Thermocouple 502 can also include, but is not limited to, a first trail 514 formed from a first thermocouple material and at least a second trail 516 formed from a second thermocouple material. As shown in figure 5B, the sensor 200 "can include numerous tracks formed from the second thermocouple material that includes, but is not limited to the second trace 516.
[00105] The first trace 514 and the second trace 516 can meet or be arranged next to each other at one or more of the junctions 512. As is known, a heat can cause an electron transfer from the first trace 514 to the second trace 516 , and the resulting voltage can be measured at or at one or more of the connectors 510 to determine a temperature at or near thermocouple 502. It can be seen from the view shown in figure 5B that the dielectric patches like the dielectric patches 414 shown in figure 4B can be omitted in some modalities of the sensor 200 ", although this is not necessarily the case. Thermocouple 502 can be printed on the substrate 500 through any suitable process that includes, for example, the use of flame spray from plasma, atomized blasted pre-arrangement, and / or other processes, as noted above.
[00106] Figure 5C is a line diagram illustrating the additional aspects of the 200 "sensor shown in Figure 5A. In particular, Figure 5C shows an illustrative implementation of the 200" sensor in an aircraft engine or other structure, according with an illustrative modality. As shown in figure 5C, sensor 200 "can be attached to an irregularly shaped or curved structure, such as a motor component 520. In the illustrated embodiment, motor component 520 includes numerous cellular structures (" cells ") 522, although this is not necessarily the case. Thus, it can be seen from the arrangement illustrated in figure 5C that the sensor 200 "can be attached to numerous cells 522.
[00107] Although the arrangement illustrated in figure 5C corresponds to an arrangement in which the sensor 200 "is fixed to an internal surface of the motor component 520, it should be understood that this is not necessarily the case. In particular, as noted above and illustrated and described in the additional detail below, the sensor 200 "can be attached to the outside of the motor component 520, if desired. Thus, it must be understood that the illustrated modality is illustrative, and should not be considered as limiting in any way. The 200 "sensor can be attached to the motor component 520 and / or cells 522 using any suitable processes or materials.
[00108] Now, with reference to figure 5D, the additional aspects of sensors 200 are described in detail. In particular, figure 5D is a line diagram that illustrates the additional aspects of the 200 "sensor shown in figure 5A, according to another illustrative embodiment. Figure 5D shows an illustrative implementation of the 200" sensor in an aircraft engine, a wall , a car engine or other structure, according to an illustrative modality. As shown in figure 5D, the sensor 200 "can be attached to an irregularly shaped structure, for example, an engine component of an aircraft engine formed from a honeycomb panel 530.
[00109] In the illustrated embodiment, the honeycomb panel 530 includes numerous cellular structures with a hexagonal profile ("hexagonal cells") 532, although this is not necessarily the case. In the illustrated embodiment, the sensor 200 "is arranged or used as a partition between the two core strips of the honeycomb type that can be assembled together to form the hexagonal cells 532 and / or the honeycomb panel 530. In several embodiments, the sensor 200 "is located on an edge of the honeycomb panel 530 next to a hot side of an engine or other structure. It must be understood that this modality is illustrative, and should not be considered as limiting in any way.
[00110] Now, with reference to figure 5E, the additional aspects of sensors 200 are illustrated in more detail. In particular, Figure 5E is a line diagram that illustrates the additional aspects of the 200 "sensor shown in Figure 5A, in accordance with yet another illustrative modality. Figure 5E shows another illustrative implementation of the 200" sensor implemented in an aircraft engine. , a wall, a car engine or other structure that includes, for example, the honeycomb panel 530 shown in figure 5D. As shown in figure 5E, the sensor 200 "can be attached to the hexagonal cells 532 of the honeycomb panel 530.
[00111] In the modality illustrated in figure 5E, the sensor 200 "is fixed to a warm side 540 of the hive-type panel 530, although this is not necessarily the case. In several modalities, the sensor 200" is located on a cold side 542 of the honeycomb panel 530 beyond, or instead of the illustrated arrangement. Thus, it should be understood that the modality shown in figure 5E is illustrative, and should not be considered as limiting in any way.
[00112] Now, with reference to figure 6, the additional aspects of sensors 200 are shown in detail, according to an illustrative modality. In particular, figure 6 is a line diagram that illustrates the aspects of a sensor 200 "'according to an illustrative embodiment. As shown in figure 6, sensor 200" "can be implemented within an engine or other structure 600 In the illustrated modality, the structure 600 corresponds to an aircraft engine panel, although it must be understood that this modality is illustrative.
[00113] The structure 600 includes, in some embodiments, the hot side, indicated in general as 602, and a cold side, indicated in general as 604. The hot side 602 can correspond, for example, to an entrance side or to a nozzle side of an aircraft engine component such as frame 600, a combustion chamber side of component 600, and / or other hot or high temperature environments, where hot or high temperature is measured in terms absolute and / or in relative terms as being a high or hot temperature in relation to the cold side 604. It should be understood that these modalities are illustrative and should not be considered as limiting in any way.
[00114] The structure 600 includes, in some embodiments, a panel insertion cavity ("insertion cavity") 606 in which a panel insertion 608 is inserted from the cold side 604 such that the panel insertion 608, and / or a part of it is in proximity to the hot side 602. It should be understood that the panel insert 608 can be inserted from the hot side 602, if desired. Thus, the illustrated modalities should be understood as illustrative and should not be construed as limiting in any way.
[00115] In various embodiments, a signal trail 610 can be arranged at or near insertion cavity 606. The signal trail 610, or a part of it, may be in contact with one or more electrical contact pads 612 located in the panel insert 608. In some embodiments, one or more dielectric trails 614 may be located close to signal trail 610 to isolate, or at least limit, a conductivity of the signal trail 610. In embodiments that incorporate thermocouples, the use of the dielectric , but not necessarily limited, be useful in enhancing the functionality of the sensor 200 '", as is generally understood.
[00116] Panel insert 608 can also include one or more thermocouple materials 616 that can be configured to meet at a thermocouple junction 618 that must be located at or near measurement point 620 within frame 600. With the insertion of panel 608 located inside the insertion cavity 606, the temperature at or near the measuring point 620 on the hot side 602 of the structure 600 can be measured using the signals measured on the cold side 604 of the structure 600. It should be understood that this modality is illustrative, and should not be considered as limiting in any way. Although the above discussion of figures 4A-6 referred to thermocouples as being included within sensors 200, 200 ', 200 ", 200'", it should be understood that thermistors, optical sensors and / or other sensors can be replaced by, or as, the thermocouples described.
[00117] Now, with reference to figure 7, the aspects of a method 700 for the detection, monitoring, analysis and performance in the data obtained with an integrated sensor system as presented here will be described in detail, according to a illustrative modality. It should be understood that the method 700 operations presented here are not necessarily presented in any specific order and that the performance of part or all of the operations in an alternative order (s) is possible and is observed. The operations were presented in the order shown to facilitate description and illustration. Operations can be added, omitted and / or performed at the same time, without departing from the scope of the attached claims.
[00118] It should be understood that the illustrated method 700 can be interrupted at any time, and does not need to be carried out in its entirety. Some or all operations of method 700, and / or substantially equivalent operations, can be performed by executing instructions that can be read by computer on a computer storage medium, as defined here. The term "instructions that can be read by computer", and variations thereof, as used in the description and in the claims, are used here to include routines, applications, application modules, programming modules, programs extensively , components, data structures, algorithms and the like. Computer-readable instructions can be implemented in various system configurations, including single processor or multiprocessor systems, minicomputers, large computers, personal computers, portable computing devices, microprocessor-based programmable electronics, combinations of the same and similar.
[00119] Thus, it should be noted that the logical operations described here are implemented (1) as a sequence of acts implemented by a computer or program modules running on a computer system and / or (2) as logical machine circuits interconnected or circuit module within the computing system. Implementation is a matter of choice that depends on the performance and other requirements of the computing system. Thus, the logical operations described here are referred to as states, operations, structural devices, acts, or modules. These operations, structural devices, acts and modules can be implemented in software, in firmware, in special purpose digital logic, and any combination thereof.
[00120] For purposes of illustration and description of the concepts in this presentation, method 700 is described as being performed by monitoring system 102 through the execution of monitoring application 106 and / or reporting application 108. It should be understand that these modalities are illustrative, and should not be seen as limiting in any way. In particular, it should be understood that any suitable device can be configured to provide functionality presented here by running suitable programs or modules.
[00121] Method 700 starts at operation 702, in which monitoring system 102 obtains data 114 from one or more of the sensors 200, 200 ', 200 ", 200"' and / or the integrated sensor system 112 As discussed above, sensors 200, 200 ', 200 ", 200" "and / or the integrated sensor system 112 can include any types of detection devices. In various embodiments, the sensors 200, 200 ', 200 ", 200'" and / or the integrated sensor system 112 include or are supplied by one or more thermocouples, thermistors and / or other devices, as well as several sensors or systems associated with the monitored system, such as an aircraft avionics system or other devices or systems.
[00122] For the purpose of describing the various modalities of the concepts and technologies presented here, the data 114 obtained in operation 702 are described as being obtained from one or more aircraft systems and by one or more sensors 200, 200 ', 200 ", 200 '". In particular, data 114 obtained in operation 702 is described as being obtained by monitoring system 102 from one or more sensors and / or aircraft system monitors and by one or more thermocouple devices, such as sensors 200, 200 ' , 200 ", 200 '". Thus, the data 114 obtained in operation 702 can include a temperature monitored or measured by one or more sensors 200, 200 ', 200 ", 200'" and / or by the integrated sensor system 112, the values corresponding to an ambient temperature or the operating temperature measured at or near the aircraft, a pressure level associated with the monitored engine, and / or other data. It must be understood that this modality is illustrative, and should not be considered as limiting in any way.
[00123] The data 114 obtained from the sensors 200, 200 ', 200 ", 200"', of the integrated sensor system 112, and / or other devices can be obtained in the monitoring system 102 through direct connections, through network connections, through communication links, and / or through other devices or links. Thus, data 114 can correspond to analog or digital signals generated or interpreted by sensors 200, 200 ', 200 ", 200'", by the integrated sensor system 112, other devices or systems, and / or by the monitoring system 102, according to several implementations.
[00124] From operation 702, method 700 proceeds to operation 704, in which monitoring system 102 obtains operational data 116. Operational data 116 can include, but is not limited to, one or more limits 118, one or more expected values 120 that are associated with the structure, system, or device monitored by sensors 200, 200 ', 200 ", 200'" and / or the integrated sensor system 112, and / or the information or data from history, and / or current operating characteristics, such as altitude, pressure command, air speed, or a Mach number. As explained in more detail here, limits 118 and / or expected values 120 can be stored as a matrix, with an individual value that is associated with each sensor location. These modalities support the analysis of the temperatures observed between the propulsion systems or other devices, structures or environments that can experience a wide range of normal operating temperatures or below the limit. For the purpose of describing the various modalities of the concepts and technologies presented here, the operational data 116 obtained in operation 704 are described here as corresponding to at least a limit 118 as a temperature limit associated with the monitored structure, and one or more expected values associated with sensors 200, 200 ', 200 ", 200'" and / or the integrated sensor system 112. Again, it must be understood that the multiple limits 118 are stored, where each of the limits 118 can be associated with a sensor specific, a sensor location and / or other aspects of the integrated sensor system 112. It should be understood that these modalities are illustrative, and should not be considered as limiting in any way.
[00125] From operation 704, method 700 proceeds to operation 706, in which the monitoring system 102 sets one or more limits 118 obtained in operation 704 to obtain an adjusted limit 118 '. As noted above, the monitoring system 102 can also generate the adjusted data values 114 'instead of generating the adjusted limits 118'. As explained above, adjusted data values 114 'and / or adjusted limits 118' can be based on data 114, limits 118, and / or operational data 116. In some embodiments, monitoring system 102 adjusts the data 114 and / or limits 118 to obtain adjusted data values 114 'or adjusted limits 118' by applying an adjustment formula or algorithm to data 114 and / or operational data 116.
[00126] For example, operational data 116 obtained in operation 702 may include a general sensor temperature matrix that includes a sensor of expected value at each sensor location, the test values based on the test analysis of the monitored structure in different operating conditions, and / or various statistical values, such as standard deviations to explain the differences between the various monitored structures, such as engines. According to a modality, the operating data 116 includes the outside air temperature settings that take into account the relationships between the expected temperatures and the known outside air temperatures, the pressure setting that takes into account the relationships between the engine pressure and expected engine temperatures, and / or additional or alternative data.
[00127] According to one modality, the adjustment made in operation 706 includes a single temperature adjustment of the external air which is made to any number of expected temperature values based on the temperature of the external air, a pressure adjustment factor calculated such as (maximum engine pressure minus minimum engine pressure), divided by (maximum engine temperature minus minimum engine temperature), and / or other settings. In some embodiments, the pressure adjustment factor is calculated at sea level. The pressure adjustment factor can be calculated in a number of ways and can be stored in a matrix that provides a value for each sensor location, if desired. Thus, the examples above are illustrative and should not be construed as limiting in any way. [00128] In one example, the general sensor temperatures used to make the adjustment in operation 706 are developed at the level of autopilot, based on the assumption that the level of autopilot corresponds to a level at which the aircraft passes the highest part of your operational flight time. A maximum autopilot pressure ("MCT") can be set based on a rated autopilot condition at 35,000 feet on a standard temperature day. The adjustment of the outside air temperature can be calculated as a difference between the actual measured conditions as reported by an aircraft air data system, for example, and a reference condition, such as the general sensor temperature described above. In particular, a standard temperature at 35,000 feet is -52.78 ° C (- 63 ° F). Thus, if an aircraft's air data system reports an outdoor air temperature of -41.67 ° C (-43 ° F), the outdoor air temperature setting would be an additional 20 degrees for all sensors, that is, the sensor reading on any of the 200, 200 ', 200 ", 200'" sensors can be expected to be 20 degrees above normal due to the external air adjustment calculated above. It must be understood that this modality is illustrative, and should not be considered as limiting in any way.
[00129] Similarly, a pressure adjustment as explained here is calculated, in an example, based on the assumption that the temperature in any of the sensors will rise by a reference amount as the pressure exceeds a pressure expected. In particular, the temperature can be expected to rise as the pressure of an engine exceeds a reference pressure, and will expect to decrease as the pressure of an engine decreases below a reference pressure. The pressure setting ("TA") can be calculated as a percentage of the maximum temperature rise proportional to the pressure command. An example of this calculation was briefly described above. In several implementations, a single pressure adjustment is calculated for each sensor or sensor location, since each location within an engine can experience a relatively higher or lower temperature rise compared to pressure-based sensors. Thus, the pressure setting can be stored in operational data 116 as a matrix, if desired. In some embodiments, the pressure adjustment matrix has the same dimensions as an expected general temperature matrix, although this is not necessarily the case.
[00130] In an example scenario, the maximum pressure for an engine is one hundred percent and the minimum pressure is equal to zero percent. A referral boost is sixty percent. The temperature at maximum pressure, determined by testing or other means, is 204.45 ° C (400 ° F) and the temperature at minimum pressure is 93.34 ° C (200 ° F). Thus, the pressure difference is calculated as (one hundred minus zero) = one hundred percent, and the pressure difference is calculated as (four hundred minus two hundred) = 93.34 ° C (200 ° F). Thus, the pressure adjustment in this scenario would be -16.67 ° C (2 ° F) for each percent of pressure applied. Thus, the pressure adjustment for a specific condition would be calculated as [(Pressure in Command - Reference Pressure) times the adjustment factor]. Thus, at 60 percent pressure - the "general" reference condition - the setting would be [(60 percent - 60 percent) times two degrees / percent)] = Zero. In the reference condition, there is no adjustment. In the reference condition above, at 75 percent pressure it would yield [(75 minus 60) times two] = 30 degrees. The reference condition below would yield a negative adjustment, for example [(50 percent less than 60 percent) times two] = minus 20 degrees. As noted above, the pressure setting may be different for each 200, 200 ', 200 ", 200'" sensor. It must be understood that this modality is illustrative, and should not be considered as limiting in any way.
[00131] In a second sample scenario, the same base reference temperatures and pressure adjustments used in the first example are considered. In the second scenario, however, the aircraft is rising by 15,000 feet in rising pressure (about 75 percent of the maximum) and the ambient temperature is negative (positive) -9.45 ° C (15 ° F). In this example, the temperature setting is (positive 15 degrees minus negative 63 degrees) = positive 78 degrees. Thus, all readings from sensors 200, 200 ', 200 ", 200'" must be adjusted by subtracting 78 degrees that reflect the 78 degrees above normal that are currently experienced on sensors 200, 200 ', 200 ", 200 "the pressure adjustment, by the example above [(75 per cent minus 60 percent) times two degrees] = 30 degrees. When considering that two sensors 200 capture the temperature readings of 179.45 ° C (355 ° F) and 180.56 ° C (357 ° F), respectively, and assuming that the general unadjusted temperatures for these two sensors 200 are respectively 262 degrees Fahrenheit and 268 degrees Fahrenheit, the operating sample calculations 706 would be (355 minus (262 plus 78 plus 30 degrees) = minus 15 degrees Fahrenheit) and (357 degrees minus (268 plus 78 degrees plus 30 degrees) = Minus 19 degrees Fahrenheit). As will be understood below, both determinations are negative and, therefore, would probably not trigger an alarm, an alert, or a warning condition. Such conditions can be considered to tend to indicate that the propulsion system is operating at lower temperatures than expected, while alarms can be set to be triggered, one hundred or more degrees above expected temperatures. It must be understood that this modality is illustrative, and should not be considered as limiting in any way.
[00132] From operation 706, method 700 proceeds to operation 708, in which monitoring system 102 compares data 114 obtained in operation 702 to the adjusted limit 118 'calculated in operation 706. In other modalities, as explained above , the monitoring system 102 compares the adjusted data values 114 'to the 118 limits. More particularly, a sensor reading obtained with sensors 200, 200', 200 ", 200 '" and / or the integrated sensor system 112 can be compared to the adjusted limit 118 'calculated in operation 706 to determine if a difference exists between the expected limit 118' the measured value, or an adjusted data value 114 'calculated in operation 706 can be compared to a limit 118 to determine whether the difference exists.
[00133] In some modalities, the comparison made in operation 706 is made by considering a general sensor temperature associated with a sensor 200, 200 ', 200 ", 200'" and / or the integrated sensor system 112, applying the external air temperature adjustment and the pressure adjustment to the general sensor temperature for the 200, 200 ', 200 ", 200'" sensor and / or the integrated sensor system 112, and compare the obtained value to the measurement obtained at from the sensor and sensors 200, 200 ', 200 ", 200"' and / or the integrated sensor system 112 in operation 702. If the difference is positive, then the data obtained 114 or the adjusted data value 114 'exceeds an expected value, such as a limit 118 or an adjusted limit 118 ', whereas if the difference is negative, the obtained data 114 or the adjusted data value 114' do not exceed an expected value.
[00134] In some modalities, positive differences above a predetermined limit can be understood as corresponding to a condition that can be reported, although this is not necessarily the case. For example, in some embodiments, a difference of one hundred degrees Fahrenheit above an expected value is determined by monitoring system 102 as corresponding to a general condition, while differences of 121.11 ° C (250 ° F) above a value expected is determined by monitoring system 102 as corresponding to a fire condition or other alarm condition. On the other hand, differences of less than one hundred degrees and 250 degrees, respectively, can be determined to not correspond to overheating and / or fire conditions. Other values, as well as ranges, deviations, rates, or other relationships can be established such as overheating, alarm, or other actionable or alarming conditions. It must be understood that a designer or other entity can specify the limits as many, or as few, as desired. Thus, it must be understood that these modalities are illustrative, and should not be considered as limiting in any way.
[00135] From operation 708, method 700 proceeds to operation 710, in which monitoring system 102 determines whether the difference calculated in operation 708 corresponds to a normal or abnormal operating state and / or whether the monitored structure is operating in an alarm condition. As noted above, if the difference calculated in operation 708 exceeds an expected value, or if the difference calculated in operation 708 exceeds an expected value by a predetermined amount, monitoring system 102 can determine that the monitored structure is operating abnormally or in an alarm state or condition. It must be understood that this modality is illustrative, and should not be considered as limiting in any way.
[00136] If monitoring system 102 determines, in operation 710, that the monitored structure is operating abnormally or in an alarm state or condition, method 700 proceeds to operation 712. In operation 712, the monitoring system 102 generates one or more alarms 122 and / or stores data 114 obtained in operation 702 in a data storage location, such as data storage device 126. As explained above, data 114 can be stored to allow analysis of data 114 data by various entities for problem solving or other purposes. Thus, the data storage described here can be performed at any time and / or at any time with or without the detection of an alarm condition, as explained above with reference to figure 1. Thus, the illustrated modality must be understood as being illustrative, and should not be construed as limiting in any way.
[00137] According to the various implementations, the data 114 stored in operation 712 includes the current temperature readings or other readings from the current sensor. So, instead of just receiving information from a flight crew or other entities that indicate that an overheating or fire condition was detected in a specific structure, the analysis can review the readings and / or data from the sensor located in relevant way with respect to space, which triggered the alarm conditions. Due to the fact that the monitoring system 102 tracks and / or stores the data associated with numerous sensors and / or locations, and due to the fact that the monitoring system 102 tracks the current sensor readings associated with these sensors and / or analysis may be able to quickly identify the location of the problem and the condition or exact reading that triggered the alarm or warning. Thus, some modalities of the concepts and technologies presented here may provide an improvement over the other sensors and / or monitoring devices that monitor the sensors that cover large areas within the monitored structures and / or that may or may not be configured to provide the current readings that can be stored and / or retrieved for analysis during troubleshooting or other analyzes. Thus, the modalities of the concepts and technologies presented here can be used to improve the solution of problems in structures associated with alarm conditions, although this is not necessarily the case.
[00138] From operation 712, or if the monitoring system 102 determines, in operation 710, that the monitored structure is operating normally and / or is not operating in an alarm condition or state, method 700 proceeds to operation 714. Method 700 ends in operation 714.
[00139] Although not shown in figure 7, data 114 can be stored for any purpose, even if no alarm or alert condition is detected. In one embodiment, data 114 is stored and can be used for diagnostics and trends. In some embodiments, a thermal map can be generated from the stored data 114. An example of a thermal map 800 is illustrated in figure 8. As shown, thermal map 800 can be generated as a thermal gradient produced considering the sensor data matrix and by plotting the data in three-dimensional positions that correspond to the positions of the associated sensors 200. Thus, the thermal map 800 can correspond to a visual representation of the environment under the hood. The thermal map 800 can be a significant tool for maintenance and diagnostic action and cannot be achieved with previous sensor systems.
[00140] Figure 9 shows an illustrative computer architecture 900 of a monitoring system 102 capable of executing the software components described here for the detection, monitoring, analysis and performance on data 114 obtained with sensors 200, 200 ', 200 ", 200'" and / or with the integrated sensor system 112 as shown here is shown, according to an embodiment. As explained above, monitoring system 102 can be implemented in a single computing device or in a combination of one or more processing units, storage units, and / or other computing devices implemented in the aircraft's avionic systems and / or of a computer system from a computer system on land. Computer architecture 900 includes one or more central processing units 902 ("CPUs"), system memory 904 including random access memory 906 ("RAM") and read-only memory 908 ("ROM" ), and a system bus 910 that couples memory to 902 CPUs.
[00141] CPUs 902 can be standard programmable processors that perform the arithmetic and logical operations necessary for the operation of the 900 computer architecture. CPUs 902 can perform the operations required by transitioning from a distinct physical state to the next via the manipulation of switching elements that differentiate between and change these states. Switching elements can generally include electronic circuits that maintain one of two binary states, such as flip-flops, and electronic circuits that provide an output state based on the logical combination of the states of one or more elements switching systems, such as logic gates. These basic switching elements can be combined to create the most complex logic circuits, which include registers, adder-subtractors, arithmetic logic units, floating point units, and so on.
[00142] Computer architecture 900 also includes a mass storage device 912. Mass storage device 912 can be connected to CPUs 902 via a mass storage controller (not shown) still connected to the 910 bus. mass storage device 912 and its associated computer-readable media provide non-volatile storage for computer architecture 900. The mass storage device 912 can store a 914 operating system, various avionics systems and control systems, as well as application-specific modules or other program modules, such as monitoring application 106, reporting application 108, and / or other programs or modules described above with reference to figure 1. The mass storage device 912 can also store data collected or used by various systems and modules, which include, but are not limited to, operational data is 116, which may include limits 118, adjusted limits 118 ', expected values 120, and / or other data. Although not shown in figure 9, mass storage device 912 can also store data 114 and / or adjusted data values 114 '.
[00143] Computer architecture 900 can store programs and data on mass storage device 912 by transforming the physical state of the mass storage device to reflect the information that is stored. The transformation of specific physical state can depend on several factors, in different implementations of the present presentation. Examples of such factors may include, but are not limited to, the technology used to implement the mass storage device 912, if the mass storage device is characterized as primary or secondary storage, and the like. For example, computer architecture 900 can store information to the mass storage device 912 by issuing instructions through the storage controller to change the magnetic characteristics of a specific location within a magnetic disk drive device, the characteristics reflective or refractive of a specific location on an optical storage device, or the electrical characteristics of a capacitor, transistor, or other specific distinct component on a solid state storage device. Other physical support transformations are possible without departing from the scope and spirit of the present description, with the previous examples provided only to facilitate the description. Computer architecture 900 can further read information from the mass storage device 912 by detecting the physical states or the characteristics of one or more specific locations within the mass storage device.
[00144] Although the description of the computer-readable media contained in this document refers to a mass storage device, such as a hard disk or a CD-ROM, it should be noted by those skilled in the art that computer-readable media can be any available computer storage media that can be accessed by computer architecture 900. By way of example, and not by way of limitation, computer-readable media may include volatile and non-volatile, removable and non-removable media implemented in any method or technology for storing information, such as instructions that can be read by computer, data structures, program modules or other data. For example, computer-readable media include, but are not limited to, RAM, ROM, EPROM, E-PROM, memory flash or other solid state memory technology, CD-ROM, digital versatile discs ("DVD"), HD-DVD, BLU-RAY, or other optical storage, magnetic tapes, magnetic tapes, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store the desired information and that can be accessed by computer architecture 900. For use in the present invention and in the claims, the term "computer storage medium" does not include the transient computer medium, such as waves or propagated signals, per se.
[00145] According to various modalities, the computer architecture 900 can operate in a network environment with the use of logical connections to other avionics in the aircraft and / or to the systems that are not on board the aircraft, which can be accessed through of a network, such as network 104. Computer architecture 900 can connect to network 104 via a network interface unit 916 connected to the 910 bus. It should be noted that the network interface unit 916 can also be used to connect other types of networks and remote computer systems. Computer architecture 900 can also include an input-output controller 918 for receiving input data and for providing data output to aircraft terminals and displays, such as a flight display, the access maintenance terminal (MAT ) or other systems or devices. The 918 input-output controller can receive data input from other devices as well, which includes, but is not limited to the primary flight display ("PFD"), an electronic flight bag ("EFB"), a "head-up" display ("HUD"), a keyboard, mouse, electronic style, or touchscreen associated with a flight display or any other systems or devices. Similarly, the 918 input-output controller can provide data output to other displays, a printer or any other type of output device.
