    LIGHTING SYSTEM WITH LOCAL MEASURED VALUE DETECTION The present invention relates to a lighting system with a plurality of lighting devices, each of which is connected to a sensor unit. The sensor units determine measured values, which are recorded and evaluated locally based on the lighting system. The lighting system according to the invention provides a communication infrastructure and the linking of the determined measured value with location information of the determining sensor unit.
    It is known to use lighting systems, for example within buildings, lighting systems with a plurality of individual lighting devices and a central control of the individual lighting devices by a central control unit. In such known lighting systems, the individual lighting devices are connected via a communication network and controlled by the central control unit via the communication network. In order to be able to selectively control individual lighting devices, each lighting device has an individual address.
    When the lighting system is started up, each lighting device is to be detected with its respective position within the area to be illuminated, for example a building.
    In addition to lighting systems, other building technology systems are known. These building technology systems include, for example, air conditioning systems or fire alarm systems. Such systems record physical parameters such as temperature, smoke concentration, CO 2 concentration with sensors distributed over a building and report the recorded physical parameters, in particular measured values and / or information derived therefrom, to one or more control units. Additional infrastructure in buildings often also includes loudspeaker systems or sensor systems, each of which must be implemented and networked in parallel to lighting systems. This involves a considerable effort for the construction of distributed infrastructure in a parallel and partially redundant manner.
    The object of the present invention is to create a location-based measured value acquisition with as little effort as possible.
    The object is achieved by a lighting system according to claim 1.
    The lighting system according to the invention comprises a plurality of lighting devices, each with a connected sensor unit and a control unit. The lighting system is characterized in that the sensor unit is set up to determine at least one measured value for an environmental parameter of the lighting device and to transmit it to the control unit via the network in which the lighting device is registered. The control unit is set up to link the transmitted measured value with position information of the connected lighting device and to determine a measured value distribution from a plurality of transmitted measured values with linked position information.
    [0008] The lighting system according to the invention enables an efficient detection of location-based measured values for physical parameters by using the lighting system infrastructure of a building for data transmission and for determining the position of the sensor unit. The construction and commissioning of parallel structures in building technology is avoided by using the existing and necessary lighting infrastructure for determining the position and communication between sensor units and control unit for data acquisition and data evaluation.
    [0009] The measured value distribution can be created, for example, on the basis of a site plan of the sensor units from the transmitted measured values. The location map of the sensor units over the building advantageously corresponds to the location map of the lighting devices connected to the sensor units, as created when the lighting system is started up

    AT 16 633 U1 2020-03-15 Austrian patent office. The individual lighting devices are provided with a luminaire address, which enables a link between the transmitted measured value, luminaire address and location information. This is an efficient way of creating a spatial measured value distribution in the form of e.g. B. a measurement card or a space-resolved analysis possible. This also makes it possible to create evaluations for a building that previously could not be created with individual, separately mounted sensors. An example of such an evaluation is the creation of a so-called temperature map. The use of the lighting system has the advantage that there is an infrastructure that can be used in a building that is widely distributed and covers the entire building in terms of area.
    Advantageous further developments of the invention are shown in the dependent claims.
    [0011] A preferred lighting system determines a measured value distribution which evaluates the transmitted measured values spatially and temporally. The spatial and temporal evaluation in particular also enables the effect of individual actuators, such as controllable radiators, to be evaluated on the measured value distribution and processed for display.
    [0012] An advantageous lighting system comprises the control unit set up to carry out a plausibility check on the measured value distribution or at least a part thereof in order to recognize at least one faulty measured value.
    This is possible in particular by comparison with the values of neighboring sensor units. A faulty sensor unit is identified by means of a plausibility check.
    An advantageous further development of the invention comprises a lighting system with the control unit designed to compensate for the detected erroneous measured value.
    The use of a distributed system with a large number of small sensor units has advantages over individual sensors, since the redundancy in the sensor units enables improved mutual monitoring of the sensors. On the one hand, the failure of individual sensor units must be compensated for, for example, by generating a simulated measured value from the measured values of the neighboring sensors by averaging. On the other hand, the failure of one or more individual sensor units can even be better recognized without each individual sensor having a complex integrated monitoring function (BITE).
    An advantageous lighting system is characterized in that the control unit is set up to compensate for the detected erroneous measured value by averaging over transmitted measured values of further, in particular spatially adjacent, sensor units.
    An embodiment of the lighting system according to the invention is characterized in that the lighting system comprises at least one actuator, wherein the at least one actuator is suitable for influencing the local environmental parameter, and the central control unit is set up, when the actuator is actuated, position information of the actuator to be determined from the measured value distribution determined.
    If an incorrect assignment of building positions to one or more actuators of the building technology system takes place during the commissioning of a building technology system, this can be recognized and corrected during operation by the sensor units distributed and the measured value distribution determined according to the invention. The actuation of an actuator leads to a change in the measured value distribution. If this does not correspond to the originally defined position data of the actuator, an incorrect position determination of the actuator can be concluded.
    One embodiment of the lighting system has as an actuator a building technology device, in particular a heating device, an air conditioning device, a window opening device and
    2/19
    AT 16 633 U1 2020-03-15 Austrian patent office
    Locking device and / or a shading device.
    Another lighting system of an exemplary embodiment comprises a central control unit which, when the actuator is actuated, creates or changes assignment information of the actuator to at least one sensor unit by means of the measured value distribution determined.
    [0021] A preferred lighting system comprises the sensor unit designed to transmit the at least one measured value via a communication means of the lighting system.
    [0022] The lighting infrastructure is thus used to avoid the development of a parallel sensor communication infrastructure and thus to reduce the costs for the building technology infrastructure as a whole.
    [0023] An embodiment of the lighting system comprises the sensor unit designed to transmit at least one measured value linked to address information of the lighting device connected to the sensor unit that determines the at least one measured value. The control unit is thus able to comprehensively assign received data to one or more measured values of a specific lighting device and thus directly assign position information to the lighting device and thus to the sensor unit, at the position of which the measured value was determined.
    A preferred lighting system is characterized in that the control unit is set up to assign the received address information of the transmitted at least one measured value to position information of the lighting device, which includes the sensor unit linked to this address information.
    In the following, the invention will be explained in more detail using exemplary embodiments and the accompanying drawings. Show it:

    Figure 1 shows an embodiment of a lighting system 1 according to the invention.
    The lighting system comprises a control unit 4 and a plurality of lighting devices 2.1, 2.2, .., 2.5, the number of lighting devices 2.i not shown being limited to the number shown in FIG. 1.
    Each of the lighting devices 2.i has at least one light module 19 with one or more light sources, for example one or more light tubes or an arrangement
    3/19
    AT 16 633 U1 2020-03-15 Austrian patent office for one or more light emitting diodes (LED). Furthermore, each lighting device 2.i has an operating device 26 (ballast), for example an LED driver circuit. The operating device 26 generates a control signal 14 for controlling the light module 19 so that it emits light of the desired properties, for example light intensity. The light output of the light module 19 is controlled by the operating device 26, the control unit 4 connected to the operating device 26 via the network 13 generating the necessary control signals 16 and transmitting it to the operating device 26 via the network 13. The control unit 4 also receives signals 15 from the individual lighting devices 2.i, for example relating to a status of the lighting devices 2.i, via the network 13.
    The control unit 4 comprises a light control unit 5 with an interface module 6 for communication with the lighting devices 2 and other elements of the lighting system 1, such as, for example, not shown in FIG. B. switches, dimmers, motion detectors. The assignment of the individual elements of the lighting system 1 to one another, that is to say the switch of a room to the lighting device 2 installed in this room, can be done via a lighting assignment table stored in a data memory 7. This lighting assignment table includes, among other things, assigned to each other, lamp address and position information of the lighting devices 2.i.
    The light control unit 5 of the control unit 4 performs the necessary control tasks for the light output and can for an entire building, for a part of a building as well as for a certain area outside a fixed building, for. B. a section of a public space such as a city district perform the control tasks for the lighting device 2.i installed in this area.
    According to the invention, the plurality of lighting devices 2.i are spatially arranged together with a sensor unit 3.i. The sensor unit 3.1, 3.2, 3.3, ..., 3.5 can be arranged in the lighting device 2.i. The sensor unit 3.i can be attached to the lighting device 2.i or can also be arranged in the vicinity of the lighting device 2.i in a separate unit. Each lighting device 2.i with a sensor unit 3.i is not necessarily arranged together in the area to be illuminated.
    The sensor unit 3.i is connected to the operating device 26 via a sensor communication connection 11. The sensor unit 3.i measures at least one environmental parameter of the sensor unit 3.i and thus also of the lighting device 2.i and transmits the measured value (sensor data) to the operating device 26 via the sensor communication link 11. The operating device 26 of the lighting device 2.i sends the received measured value Via which the network 13 to the control unit 4. The interface module 6 of the light control unit 5 receives the measured values (sensor data) of the plurality of sensor units 3.i in the signal from the operating device 26 of the individual lighting devices 2.i extracts the measured values and transmits them to an Sensor control unit 10.
    The sensor control unit 10 of the control unit 4 can, but need not necessarily, be arranged together with the light control unit 6. The individual elements of the control unit 4 can be arranged in a distributed manner and, for example, can be connected to one another via the network 13. For example, an Internet protocol, in particular IPv6, can be used as the communication protocol for the individual elements of the control unit 4.
    The sensor control unit 10 is set up to store, read and change a sensor assignment table in the data memory 7. This sensor assignment table comprises an assignment of a lamp address of each lighting device 2.i to the respective sensor units 3.i, which is arranged together with the lighting device 2.i. A measured value transmitted by the lighting device 2.i or its operating device 26 via the network can be assigned to a lamp position on the one hand and to a sensor unit 3.i connected to the lamp address via the lamp address transmitted together with this measured value. This enables transmission of measured values (sensor data) via the network 13 set up for the lighting, without the need to set up a parallel sensor network.
    4/19
    AT 16 633 U1 2020-03-15 Austrian Patent Office [0042] The sensor control unit 10 can store the measured values assigned to the individual sensor units 3.i in the data memory 7. The stored measured values can be read out from the data memory 7 for further evaluation and display and transmitted as measurement data 8 to data processing systems. The location-related measurement data determined with the lighting system 1 according to the invention enable numerous other applications, which are briefly described below.
    Today, the various trades in building technology work with proprietary applications, buses and communication protocols. The preferred embodiment of the invention provides for the measured values of the sensor units 3.i to be transmitted (transported) over the network 13 via a uniform communication protocol, in particular the Internet protocol IPv6.
    It is also preferred to store the transmitted measured values and in a standardized format, in particular HTML5, in the data memory 7. It is advantageous to convert the data of the measured values into different data formats as required and to provide proprietary solutions in a converted form.
    FIG. 2 shows a schematic illustration of a lighting device 2.i for use in a lighting system according to an exemplary embodiment of the invention.
    The lighting device 2.i connects an additional module 14 with a CO 2 sensor 20 as an example for a sensor unit via an intelligent interface unit. Thus, for example, a measurement value acquisition function can be implemented in addition to the emergency light function of the lamps 23, 24 via the intelligent interface unit. The data of the CO 2 sensor 20 can be transmitted via the intelligent interface unit and the operating device or also directly to a control unit 4.
    Illumination devices 2.i according to the invention with additional modules, each with an integrated CO 2 sensor 20, can be distributed over the building as part of an emergency lighting system. Accordingly, it is possible to determine a CO 2 concentration over the entire building using the correspondingly upgraded emergency lighting system, determine a corresponding CO 2 distribution and make it available for other applications. These further applications can include, for example, guiding people within the building to an escape route with the lowest CO 2 concentration based on an evaluation of the CO 2 distribution thus determined over the building in the event of a fire. Furthermore, it becomes possible to provide an operational manager of a rescue service deployment with the information for a targeted use of respiratory protection wearers by providing the CO 2 distribution determined in this way at a suitable external interface.
    According to the invention, the information about the CO 2 (smoke) situation can thus also be obtained via a suitable sensor unit in the lighting device 2.i. Since the CO 2 sensor 20 cannot recognize from a locally detected, increased CO 2 concentration where the CO 2 comes from, a combination of the results of several CO 2 sensors 20 in several lighting devices 2.i is advantageous. For example, appropriately equipped lighting devices 2.i can transmit their determined CO 2 measured values to the control unit 4. This control unit 4 also has the position information of the individual lighting devices 2.i. This position information is, for example, either entered manually or generated automatically as part of the initialization (addressing) of the individual lighting devices 2.i using a method for determining the position. The control unit 4 uses the position information and the measurement data of the lighting devices 2.i to determine a CO 2 distribution in a building. Based on this information, laser diodes of the lighting devices 2.i according to the invention can be controlled and people can be guided to safe areas on an escape route with the lowest CO 2 concentration.
    If the sensor unit 3 comprises the CO 2 sensor and increased CO 2 measured values are measured as measured values and transmitted to the control unit 4, the control unit 4 can automatically actuators such. B. start ventilation and / or window control to by means
    5/19
    AT 16 633 U1 2020-03-15 Austrian patent office
    Fresh air automatically keep the air quality at a predetermined level. Compared to time-controlled window controls, the best air quality is always guaranteed, unnecessary heating in summer or cooling of the room in winter is prevented.
    Likewise, a CO 2 sensor used as a sensor unit 3 can be used for fire prevention. If increased CO 2 measured values are measured as measured values and transmitted to the control unit 4, the control unit 4 can automatically, in particular, for example, in conjunction with measured values for high ambient temperatures of an additional temperature sensor module
    17, can be concluded from a fire. An alarm SMS and / or an emergency call can be made to the building manager and the fire department via the lighting system. People who have logged on to the building using a mobile communication device can also receive a warning.
    The control unit 4 can automatically create a fire or smoke map of the entire building by means of the transmitted measured values and the link to the position information. This fire or smoke card is automatically transmitted to the fire service by the control unit 4 of an embodiment of the lighting system. This enables a quick analysis of where the sources of the fire are and when using presence sensors
    18 where people are at risk. With this fire or smoke card, fire fighting and rescue can be carried out quickly and in an optimized manner. PIR sensors or ultrasonic sensors, for example, can be used as presence sensors 18.
    [0052] Furthermore, the control unit 4 is designed to implement a dynamic escape route display. On the basis of a CO 2 map of the building generated according to the invention, the control unit 4 can locate sources of fire in the building and thus control a dynamic escape route display accordingly. Depending on the fire situation, people can be guided dynamically out of the building. This information on escape routes can also be sent wirelessly to an emergency application on mobile devices of people who are inside the building.
    Are the control unit 4 additionally also presence information, z. B. determined by a presence sensor 18 or a camera sensor module, flows of people can also be directed so that there is no mass panic.
    Similar to the emergency application, presence information transmitted by presence sensor modules 18 in conjunction with the position information of the lighting devices 2 can also be used to analyze customer flows within a shop and to adapt a presentation concept based thereon. The data determined with the lighting system 1 according to the invention are therefore particularly advantageous since they are not determined once during a test and are therefore not representative. Instead, the data is continuously determined during operation.
    The CO 2 maps can be used to locate the source of the fire and thus to control a dynamic escape route display. Depending on the fire situation, people can be guided dynamically out of the building. This information can also be sent wirelessly to an emergency application on a mobile communication device (smartphone). If there is also presence information, for example by presence sensors 18, flows of people can additionally be directed in a targeted manner so that there is no mass panic.
    The lighting device 2.i in FIG. 2 connects a presence sensor 18 via an intelligent interface unit of the operating device. The intelligent interface unit thus realizes, for example, the presence of people in the detection range of the presence sensor 18 in addition to the emergency light function of the lamps 23, 24. The data of the presence sensor 18 can be transmitted to the control unit 4 via the intelligent interface unit and the operating device of the lighting device 2.i and evaluated there.
    The spatial position of the individual emergency lights in the building is generally known to an emergency lighting system. The use of presence sensors 18 in connection with the lights
    6/19
    AT 16 633 U1 2020-03-15 Austrian patent office
    Devices 2.i enable targeted control of general lighting without having to create a separate control infrastructure for general lighting.
    The lighting device 2.i shown in Figure 2 also shows a temperature measuring module 17, which has a transmitter for determining an ambient temperature. The measured temperature measurement values are via the operating device 26 of the lighting device
    2.i transmitted to the control unit 4. In a simple exemplary embodiment of the lighting device 2.i, the temperature measuring module 17 can be a temperature monitor for monitoring an operating temperature of the lighting device 2.i itself, which has a suitably designed calibration for detecting an ambient temperature of the lighting device 2.i. Since, according to the invention, a large number of lighting devices 2.i are arranged in a building together with sensor units 3, the low accuracy of an individual temperature measuring module 17 is compensated for by the large number of measured values of the large number of available temperature measuring modules. If a temperature measurement module 17 fails, the temperature measurement modules 17 of adjacent lighting devices 2 provide temperature measurement values that enable the control unit 4 to determine a temperature value also for the position of the failed temperature measurement module 17. Compensation of a failed temperature measurement module 17 is thus possible, for example by averaging, in particular by averaging taking into account a spatial distance from the failed temperature measurement module 17.
    Temperature measurement modules 17 integrated with the lighting system 1 according to the invention can determine the spatial temperature distribution and temporal temperature profiles in a building. For example, a temperature sensor is usually already integrated in emergency lights with lithium-ion batteries. Here either electronics integrated in the lighting device 2.i can automatically calculate the self-heating of the lighting device 2 and thus determine the ambient temperature. Alternatively, the control unit 4 can adjust the transmitted measured value accordingly.
    The control unit 4 automatically generates a measured value distribution from this data, in particular in the form of a measured value card. This allows a building manager to quickly determine the operating parameters of the installed heating and air conditioning system and optimize them accordingly.
    According to one embodiment of the invention, the lighting system according to an embodiment of the invention is used before the installation of a heating-ventilation-air conditioning (HVAC) system in the construction phase to measure the peculiarities of the building by means of positionally accurate measurement of important parameters such as temperature, train , ... in order to build the HVAC system optimally based on the building.
    In addition to manual optimization by the building manager, automatic optimization is also possible. The control unit 4 or an external evaluation unit analyzes the transmitted measured values, determines optimized parameters for the HVAC system and sends these parameters via a standardized communication protocol, e.g. IPv6, for the heating / ventilation system.
    By means of the different sensor units 3.i, which are arranged in the lighting devices 2.i or in a narrow spatial environment of the lighting devices 2.i, further advantageous applications of the lighting system 1 according to the invention can be realized.
    Using the sensor data, the software can automatically create a fire or smoke map of the entire building. This fire or smoke card can be automatically sent to the fire department. The fire brigade thus sees at a glance where the sources of the fire are and where, when presence sensors 18 are used, there are people at risk. With these cards, fire extinguishing and rescue operations can be optimized and accelerated. The sensor unit 3.i is discussed in FIG. 2 on the basis of the temperature measurement module 17, the presence sensor module 18 and the CO 2 measurement module 20. Alterna

    AT 16 633 U1 2020-03-15 Austrian patent office or additionally, the sensor unit 3.i can comprise a smoke detector, a fire warning sensor, a gas sensor, a moisture sensor or another sensor measuring any environmental parameter of the lighting device 2.i.
    In Figure 3, essential functional blocks of the lighting device 2.i are shown.
    The lighting device 2.i has an LED module 25 for the primary lighting function of the lighting device 2.i. The lighting device 2.i can be an emergency light, so that the lighting device 2.i also has a battery 29 in order to ensure operation even if the power supply to the lighting device 2.i fails. An operating device 26 of the lighting device 2.i controls the LED module 25. The operating device 26 provides an interface to the external power supply, ensures the electrical isolation between the primary mains voltage side on the one hand and the secondary low voltage side to the battery 29 and LED module 25 on the other hand. The operating device 26 can also implement a dimming function by suitable control of the LED module 25. The operating device 26 receives a dimming value to be set via a communication interface 28. The communication interface 28 of the lighting device 2.i is shown in FIG. 3 with a large number of different communication standards for communication. For the lighting device 2.i according to the invention, communication according to at least one of the communication standards shown in FIG. 3 or a corresponding standard not shown in the drawing in FIG. 3 is essential.
    [0067] Examples of transmission protocols of the communication interface 28 include a DALI (Digital Addressable Lighting Interface) or eDALI interface, a PLC interface (Power Line Communication), an IPv6 interface, an Ethernet interface, a short-range communication interface like NFC, a WPAN 802.15.4 interface like ZigBee, an 802.15.1 interface (Bluetooth ™, Bluetooth Low Energy-BLE).
    The lighting device 2.i according to the invention further comprises a sensor / actuator interface 27. In FIG. 3, the sensor / actuator interface 27 is connected via the operating device 26 both to a voltage supply and to the communication interface 28. On the one hand, sensor units 3.i and actuators are supplied with the necessary operating voltage via the sensor / actuator interface 27.
    On the other hand, control signals are transmitted to sensors and actuators, which the operating device 26 receives via the communication interface 28.
    In the context of the lighting system according to the invention, the operating device 26 receives measured values from the sensor units 3.i. connected via the sensor / actuator interface 27 via the sensor / actuator interface 27. The received measured values are transmitted from the operating device 26 to the control unit 4 via the communication interface 28 to the network 13. The operating device 26 shown in FIG. 3 is set up to convert the received measured values from the sensor units 3.i into suitable data formats for transmission via the communication interface 28 and to transmit them via the communication interface 28.
    Alternatively or additionally, the lighting device 2.i can have correspondingly designed circuits or appropriately programmed processors in order to receive the measured values from the sensor units 3.i via the sensor / actuator interface 27 and to the control unit 4 via the communication interface 28 to transfer.
    Shown in FIG. 3 is a lighting device 2.i, which has an interface 28 for sensor units 3.i arranged externally to the lighting device 2.i. Alternatively or additionally, the lighting device 2.i can have internally arranged sensor units 3.i. As an alternative or in addition, the sensor unit 3 can also be implemented by monitoring the operating temperature of the lighting device 2.i or of the operating device 26. The sensor / actuator interface 27 of the lighting device 2.i can be implemented, for example, via an internal light bus in the lighting device 2.i, the sensor units 3.i are thus to be integrated directly into the lighting device 2.i.
    8/19
    AT 16 633 U1 2020-03-15 Austrian Patent Office [0073] Alternatively or additionally, the lighting device 2.i can control 27 actuators via the sensor / actuator interface and transmit suitable actuation signals to these actuators. For example, the lighting device 2.i can control an air conditioning device, regulate a radiator, control a window opening and closing mechanism, control a shading device for a window via the sensor / actuator interface 27.
    [0074] Using the flow chart in FIG. 4, a method for linking sensor data with local position information according to the invention is shown. The sensor data can then be made available to other trades as standardized sensor maps. This means that a light management system can be equipped with a secondary additional function for the entire building management regardless of its primary function “lighting”.
    It is known to provide a sensor unit 3.i or a lighting device 2.i with an integrated sensor unit 3.i with its local position information. For this purpose, the steps addressing the sensor unit with an abstract number, importing a building plan, logically assigning the address to a position in the building plan are carried out.
    For the implementation of the invention, however, according to FIG. 4, manual determination and assignment of the position information is preferably proposed during the installation of the sensor unit 3.i in a lighting device 2.i.
    The method shown in FIG. 4 initially includes step S1 of reading (importing) the building plan into an application program for initializing (picking) units of lighting technology. The position of the lighting device 2.i or the position of the sensor unit 3.i on the building plan is then designated in step S2. In a third step S3, address information is transferred to the lighting device 2.i, for example by means of NFC communication.
    An operating device 26 of the lighting device 2.i can have an NFC communication function (NFC - Near Field Communication). For this purpose, an NFC module in the lighting device 2.i is used. The lighting device 2.i can thus be configured and addressed via an NFC connection.
    The address information of the lighting device 2.i is transferred from the lighting device 2.i, in particular its operating device 26, to a mobile operating device for picking. This can be done automatically by means of user input or preferably via a wireless connection.
    If a user addresses the lighting device 2.i with the mobile operating device, e.g. a smartphone or a portable computer that, like the lighting device 2.i, has an NFC communication function, the user can manually adjust the position of the sensor unit 3.i or that with a sensor unit on a building plan in an application program installed on the mobile operating device 3.i indicate equipped lighting device 2.i. In one embodiment of the invention, the building plan is imported as a file in a file format such as “.PDF” or is outlined manually. The user can use a gesture to designate the position in the building plan at which the lighting device 2.i and the sensor unit 3.i are located.
    Optionally, position data can also be transmitted as Cartesian coordinates (x, y) to the operating device 26 of the lighting device 2.i. As an alternative or in addition, the operating device 26 can thus transmit a measured value in connection with position data, for example the Cartesian coordinates, to the control device 4.
    The application program stores a data record comprising the address information of the lighting device 2.i together with the designated position of the lighting device 2.i. In particular, the application program reads in the luminaire address and the position information of the lighting device 2.i and, on the basis of this and further data records, creates an assignment table for further lighting devices 2.i. This mapping table will

    AT 16 633 U1 2020-03-15 Austrian patent office stored in data memory 7. This method enables the automatic generation of a spatial image of the lighting system 1 above the building plan. All lighting devices 2.i can now be controlled via a graphic system image. At the same time, a graphical representation of the spatial sensor network consisting of the sensor units 3 over the building is thus created and is available in the data memory 7.
    As an alternative or in addition, the position data can be determined automatically. For this purpose, a corresponding mobile operating device with a localization function automatically determines its own position in a building during installation (picking) if it is in the vicinity of the lighting device 2.i to be installed and the sensor unit
    3.i is located. The determined position is then transmitted to the lighting device 2.i in the form of position data. This localization function can be implemented by means of any positioning method that is particularly designed for localization within buildings. This is possible e.g. using so-called micro-electro-mechanical systems (MEMS sensors), e.g. Acceleration sensors, gyroscopes ... based on microelectronics, which, based on the last available navigation signal from a satellite-based navigation system, can determine the position of the mobile operating device in the room. In the method discussed, an allocation table is also created based on this and other data sets for further lighting devices 2.i. This allocation table is stored in the data memory 7.
    The assignment table (lighting assignment table) enables, together with the sensor assignment table, an assignment of a lamp address of each lighting device 2.1 to the respective sensor unit 3.i, which is arranged together with the lighting device 2.i, the unambiguous spatial assignment of each measured value transmitted with a lamp address .
    A measured value transmitted by the lighting device 2.i or its operating device 26 via the network can be assigned via the lamp address transmitted together with this measured value to a lamp position on the one hand and to a sensor unit 3.i connected to the lamp address, ie also to a sensor position , and thus also be evaluated and displayed accordingly.
    FIG. 5 shows an illustration according to the invention of the location-related measured value distribution. One possible representation is the form of a temperature distribution map in which critical sensor data, for example increased CO 2 values, increased noise pollution or specific temperature ranges, are represented as areas in a specific color or with a specific pattern. Depending on the user, colors can be assigned for different levels, so that an intuitively perceptible representation of the transmitted measured values of the sensor units
    3.i is generated.
    The representation according to the invention shown in FIG. 5 of the measurement distribution generated is given in the form of a map in the plane of a building plan spanned by the x-axis 30 and the y-axis 31. Each measured value is plotted in accordance with its value in the direction 32. The higher a transmitted measured value in the direction of the z-axis 32, the higher the point on the map above the base area. The coordinate on which a measured value is plotted is determined by the position of the sensor unit that determines the measured value
    3.i determined in the x-y plane of the measured value card. This creates measured value mountains 33 and measured value valleys 34. A mountain of a temperature distribution as an example for a measured value distribution in the room would e.g. Show elevated temperatures at this position. A user of the lighting system according to the invention or a correspondingly designed, automatically running control program can optimize the air conditioning system of the building on the basis of the measurement card generated.
    The temperature distribution shown in FIG. B. remove that a central heating circuit heats up strongly. At the edge regions of the temperature distribution shown in FIG. 5, a significantly lower temperature can be seen, possibly due to a cooling window front. Let from the intuitively understandable representation in Figure 5

    AT 16 633 U1 2020-03-15 Austrian patent office derives a manual readjustment of the central heating circuit or automatic readjustment for the user of the building, also in the area of the window front is a heating up, an improvement of the seal or replacement of the windows as possible measures derive from the representation of the measured value distribution in FIG. 7.
    6 shows a correction of an incorrect spatial sensor-actuator assignment of a building technology system according to an exemplary embodiment of the invention.
    For building technology systems, sensors generally have to be manually assigned to the corresponding actuators during installation and commissioning. The lighting system 1 according to the invention enables this process to be automated. For this purpose, the building plan is read in directly by a commissioning program in a suitable data format or first converted into a suitable data format and then read in. The software therefore recognizes which actuators, e.g. Lighting devices 2.i, but also heating, window openers, blinds, close to which sensor units 3.i, z. B. temperature sensors, are located and then automatically assigns these sensor units 3.i to the adjacently arranged actuators.
    FIG. 6 shows an embodiment in which the building technology system is dynamic and / or self-learning. The software always monitors the functioning of the work to be monitored (e.g. a heater). If the optimum is not reached, the sensor-actuator assignment is changed dynamically.
    An upper situation for the sensor-actuator assignment of a building technology system is shown in the upper partial figure 6. The actuator A1, e.g. B. a heater is assigned to 70% of temperature sensor S1 and 30% of temperature sensor S2. In the present case, the temperature sensor S1 reports a room temperature with a measured value of e.g. B. 18 ° C. In the case shown, temperature sensor S2 reports a room temperature with a measured value of 25 ° C. A desired room temperature is now not reached despite actuation of a heater. The reason for this is that the assignment of the sensor-actuator as made during commissioning and shown in the upper part of figure 8 is not correct. The heater is closer to temperature sensor 2 than to temperature sensor 1. On the basis of the evaluation of a time course of the measured value distribution for the temperature, the incorrect assignment can be recognized and the control unit 4 changes the corresponding assignment of sensor units S1, S2 to actuator A1 according to the lower part of FIG. 8. In the lower sub-figure 6, the actuator A1 (heating) is assigned 30% to the temperature sensor S1 and 70% to the temperature sensor S2. The position-specific assignment of the sensor units 3 thus enables a subsequent adaptation of an incorrect assignment of sensor units 3 to actuators and thus enables the implementation of a self-learning building technology system.
    The lighting system 1 according to the invention with the sensor units 3.i assigned to the lighting devices 2.i realizes a distributed sensor network using simple means. In known sensor systems, a central sensor is usually used. This sensor has to acquire measured values with a correspondingly high accuracy and reliability and is therefore expensive.
    In a distributed sensor system according to the invention, sensor units 3.i with lower measurement accuracy and therefore correspondingly more cost-effective sensors can be used. The control unit 4 of an exemplary embodiment uses statistical methods in order to determine exact sensor data of a higher accuracy from the transmitted measured values linked with the respective position information. The control unit 4 uses, for example, a method for averaging the measured values of a plurality of adjacent sensor units 3.i to produce a measured value that is more accurate than the transmitted measured values.
    The control unit 4 of one embodiment is designed to automatically filter out extreme measured values if these do not exceed the measured values of directly adjacent sensor units
    3.i be confirmed. The control unit 4 is thus able to infer and identify an incorrectly functioning sensor unit 3.i. The control unit 4 can for this / 19th
    AT 16 633 U1 2020-03-15 Austrian patent office
    For the purpose of comparing the transmitted measured values and with the position information of the sensor unit 3.i using a Gaussian distribution or a threshold value.
    By means of the lighting system 1 according to the invention, a largely redundant sensor system can be implemented, within the scope of which the lighting system 1 compensates incorrect measured values transmitted by the measured values of adjacent sensor units 3.i. In the case of known sensor systems, on the other hand, if a single sensor fails, an entire area can no longer be detected and therefore can no longer be controlled. The control unit 4 of an exemplary embodiment is set up to use a dynamic statistical method to compensate a measured value of a failed sensor unit 3.i by a calculated value on the basis of the transmitted measured values of the adjacent sensor units 3.i. This is made possible by the inventive linkage of the position information of the lighting device 2.i with the respective transmitted measured values.
    The control unit 4 according to the invention can thus generate a precise virtual sensor based on a large number of inaccurate and therefore inexpensive sensor units 4, which covers an entire building and can record and provide measured values in a redundant and fail-safe manner.
    [0098] Above, the invention has been illustrated using a lighting system for the interior of a building. The invention can also be used advantageously outdoors.
    [0099] The lighting system in the outside area can include street lights as lighting devices 2.i integrated sensor units 3.i. The sensor units 3.i used are designed to detect vehicles, cyclists and pedestrians. The control unit can thus switch 4 traffic lights and thus optimize a traffic flow. If the system is connected to the Internet based on the IPv6 communication protocol, alternative routes can also be sent to navigation devices in traffic jams using infrastructure-to-vehicle communication.
    The correspondingly determined measured value cards can also be used to analyze the effect of new road structures, e.g. the alleviation of traffic jams by an additional lane or by a new roundabout.
    The lighting system 1 according to the invention can also be used to monitor building structures with regard to earthquakes. For this purpose, acceleration sensors and / or gyroscopes designed as MEMS sensors (micro electro-mechanical system) are to be used as sensor units 3. The sensor units 3.i can detect minor movements in the building structure. Due to the lighting system 1 distributed over the building, in particular a high-rise building, very precise measured values can be determined and assigned in a positionally accurate manner despite inexpensive sensor units 3.i. Additionally or alternatively, LEDs in combination with a photo sensor could also be used as sensor units 3.i, the photo sensor recognizing deviations in the luminous flux and thus being able to detect vibrations in the building structure. The measured values determined in this way can be used, for example, to alert the general public and the occupants of the building as an early warning system. Furthermore, the behavior of the building in the event of an earthquake can be analyzed by means of a graphic representation of the measured values and their spatial distribution in the building. This analysis can be used to constructively optimize future building structures.
    All of the above features can be combined with one another in an advantageous manner within the scope of the invention defined in the patent claims.
