    FIELD OF THE INVENTION
    [001] This invention relates generally to vehicle systems and networks, such as railway systems including trains that travel on a rail or railroad network and, in particular, to systems and methods of data storage and management for use in connection with one or more data sources or inputs, such as event recording systems and associated devices, used in or in connection with one or more locomotives or train cars. DESCRIPTION OF RELATED TECHNIQUE
    [002] Vehicle Systems and Networks exist all over the world, and, at any point in time, a multitude of vehicles, such as cars, trucks, buses, trains, and the like, are traveling along the system and network. Many of these vehicles are equipped with various target devices that measure, determine and/or track certain conditions, parameters, operating states, physical data or information, and the like. For example, a train may include an event recorder and/or other components or devices that measure, determine and/or track certain conditions or states of train equipment, such as pressure, temperature, speed, operating states, and the like, and/ or conditions or states of areas or environment in or around the train. These devices are typically affixed to or associated with one or more of the locomotives on a train. In yet another example, these event recorders and/or other components or devices are affixed to or associated with a truck, bus or other vehicle, in which the conditions and states of certain pieces of equipment are or must be tracked.
    [003] In relation to railway systems, and as is known, recorders and train event recording systems receive and store train event data from a train management system and/or other components and systems of a locomotive, wagon, railroad network, trackside equipment, train end unit, train tip device unit, and the like, in which this information and data refer to the operating conditions or states of the train, of the area in the train, the area or environment around the train, and the like. Train event recording systems are designed to be shock resistant and include shock resistant brackets to preserve recorded train event data in the event of a crash, derailment, or other type of accident.
    [004] Recorders and train event recording systems may provide download or transfer options to facilitate the transfer of train event data to one or more external storage devices. In addition, The Federal Railroad Administration (FRA) as in 49 C.F.R. § 229 requires train event recording systems to meet basic specifications such as memory shock resistance, although the capabilities of these systems can be improved beyond these requirements. To comply, all major train locomotives in the United States that travel faster than 30 miles per hour on a US railroad network must have crashproof recording systems that record certain safety-critical events, necessary to investigate an accident.
    [005] Train event recording systems can monitor a variety of analog and digital outputs from the train management computer, directly from certain target devices, which produce data and information, and/or from other equipment and sources. Various existing train event recording systems and train management systems are shown and described in U.S. Patent Nos.: 7,965,312; 7,593,963; 8,420,930; 5,185,700; 7,703,291; and 6,795,759; US Publications No.: 2003/0222981; 2011/0216200; 2006/0244830; 2003/0081121; and 2003/0081127; and Publications No.: WO 2007064671; WO 2008144163; and WO2008005620.

    [023] For the purposes of the description hereinafter, the terms "top", "bottom", "right", "left", "vertical", "horizontal", "top", "bottom", "lateral", "longitudinal" and derivatives thereof shall refer to the invention as oriented in the drawing figures. However, it is to be understood that the invention may assume several variations and alternative step sequences, unless expressly specified otherwise. It is also to be understood that specific devices and processes illustrated in the accompanying drawings and described in the specification below are simply exemplary embodiments of the invention. Thus, specific dimensions and other physical characteristics related to the achievements revealed here should not be considered limiting.
    [024] As used herein, the terms "communication" and "communicate" refer to the reception, transmission or transfer of one or more signals, for example, electrical signals, electricity, current, energy and the like, messages, commands, and/ or type of signal or data. For a unit or device to be in communication with another unit or device, it means that a unit or device is capable of receiving signals or data from and/or transmitting signals or data to the other unit or device. A communication can use a direct or indirect connection and can be wired and/or wireless in nature. Additionally, two units or devices can be in communication with each other, although the transmitted signals or data can be modified, processed, routed etc., between the first and second units or devices. For example, a first unit may be in communication with a second unit, although the first unit passively receives signals or data, and does not actively transmit signals or data to the second unit. As another example, a first unit may be in communication with a second unit, if an intermediate unit processes signals or data from one unit and transmits processed signals or data to the second unit. It will be appreciated that several other arrangements are possible. Any known electronic communication protocols and/or algorithms can be used such as, for example, TCP/IP (including HTTP and other protocols), WLAN (including 802.11 and other radio frequency-based protocols and methods), analog transmissions and/or similar . Also, as used hereinafter, the term "electrical communication" refers specifically to the transmission of electrical signals (eg, electricity, current, power, and the like) between two or more units or devices.
    [025] The terms "data recording unit" and "data recording system", as used interchangeably herein, may refer to any data recording unit for a vehicle and, in a preferred and non-limiting embodiment, refer refer to a train event recorder and/or train event recording system, which can refer to any event recording device or system used in a locomotive, wagon, or train, which records train event data . The data logging unit and data logging system may include one or more hardware and/or software components in communication with one or more components and/or systems, i.e. data sources, of a vehicle, including a train or railway , such as, but not limited to, a train management computer, a train end unit, a train end unit, trackside equipment, operator interfaces and/or other similar systems and components. In this context, the data recording unit and/or data recording system, according to the present invention, can be used to receive, process, record and/or store data representing information about locomotives, wagons, trackside equipment , railroad signals, and/or train operators, including, but not limited to, speed, lockout pressure, error signals, system states, ready signals and user inputs, mandatory directories, movement authority signals, alerts and backup information, traffic direction, travel distance, throttle position, lock operation, highlight status, horn operation, cable signals, audio data, video data, and/or the like, as well as data and information directed to the surrounding areas or internal and/or external environment in or around the train, wagons, locomotive, and the like. In addition to train event recorders installed in a locomotive and communicating with a train management computer, event recorders may also include wagon event recorders as described by U.S. Patent No. 7,769,509 by Gaughan et al. , the integrity of which is hereby incorporated by reference.
    [026] The present invention is directed to a data recording system 1 and data recording unit 10 which are useful in connection with data recording systems for vehicles. As discussed above, and in a preferred and non-limiting embodiment, the data logging system 1 and the data logging unit 10 according to the present invention are used in or in connection with the locomotive and/or train. As such, the data logging system 1 and the data logging unit 10 can be integrated with or used in connection with new or existing train event recorders and train event recording systems. Several preferred and non-limiting embodiments of the data logger system 1 and data logger unit 10 according to the present invention are illustrated schematically in Figures 1-8.
    [027] With specific reference to Figure 1, and in a preferred and non-limiting embodiment, a data logging unit 10 is provided for a vehicle (now shown), such as a locomotive or train. The data logger unit 10 includes at least one data logger housing 12 which is configured to house certain internal components, as discussed below. This data logger housing 12 is sized, formed or configured to be affixed to and/or integrated with various parts of the vehicle, as in a train locomotive. Typically, the data recording unit 10 is attached or integrated with the locomotive, so that it survives any accident or incident involving the train, and retrieved in the scenario in order to extract the data and obtain a better understanding of the conditions or states of the train, its various components, and/or the surrounding area or internal or external environment of the vehicle.
    [028] At least one data processing unit 14 is located in the register housing 12 and programmed or configured to directly or indirectly receive data input from at least one, and typically multiple, DS data sources that are associated with the vehicle or the environment around you. Furthermore, at least one storage device 16 is in direct or indirect communication with the data processing unit 14 and configured to store data received from the data processing unit 14. In this preferred and non-limiting embodiment, the storage device 16 is in the form of a shock-consolidated solid-state storage device that is located within a shock and/or fireproof housing 18. It will be appreciated that the solid-state storage device may also be shock-unconsolidated. In particular, this shock and/or fireproof housing 18 is positioned within the data logger housing 12. In this way, the storage device 16 is additionally protected, i.e. in addition to the protection of the data logger housing 12 , in the event of a shock, fire, accident, or other incident involving the vehicle. This provides an additional level of protection for the data that is received by the data processing unit 14 and stored in the storage device 16; again, for use in data analysis before, during, or after the event. For example, the extraction of data from storage device 16 can occur at any time, but typically occurs periodically or after an incident has occurred.
    [029] In another preferred and non-limiting embodiment, and as illustrated in Figure 2, the data recording unit 10 includes a local storage device 20, which is in direct or indirect communication with at least one network storage device 22. In operation, some or all of the data input that is provided by the data processing unit 14 to the local storage device 20 is wirelessly transferred to the dynamic network storage device 22 periodically on a predetermined basis, substantially continuous, or any combination thereof. In this way, if there is a catastrophic vehicle incident where the data logging unit 10 is irretrievable or completely destroyed, the data is still available via the network storage device 22. In another preferred and non-limiting embodiment, the data logging device network storage 22 is a remote storage device, and may also be the form of a virtual memory or storage device accessible via wireless or network communication.
    [030] In another preferred and non-limiting embodiment, the local storage device 20 includes or is in the form of a network-enclosed storage device. In this example, the local storage device 20 may have a logical partition dedicated and/or configured to act as local storage, and a logical partition dedicated and/or configured to act as network storage. The network storage partition may be available to other devices communicating with the network. In this realization, it is anticipated that only specific data inputs and/or outputs could be saved to or used by the dedicated logical partition and/or configured as network-enclosed storage.
    [031] In a preferred and non-limiting embodiment, the local storage device 20 is in the form of a crash-consolidated memory that meets FRA-specific standards and regulations. However, it will be appreciated that unconsolidated memory against shocks can also be used and that, in some non-limiting realizations, both consolidated memory against shocks and unconsolidated memory against shocks can be used. Similarly, and in a further preferred and non-limiting embodiment, the local storage device 20 is located within a shock and/or fireproof housing 18, which is positioned within the data logger housing 12. preferred and non-limiting embodiment, the DS data source is in the form of a VC video camera or similar visual capture device, and the data processing unit 14 is configured or programmed to transmit or cause a transmission of video data to the network storage device 22.
    [032] Referring to Figure 3, and in another preferred and non-limiting embodiment, the data recording unit 10 includes at least one internal time source 24. In that embodiment, the data processing unit 14 is programmed or configured to synchronize data from the variety of data inputs based, at least partially, on that internal time source 24. Using the internal time source 24 to synchronize data across some or all of the data streams provides for accurate reproduction and analysis of the arrival data . These data inputs can be in the form of a variety of interfaces or ports 26. For example, as illustrated in Figure 3, these data inputs can include an Ethernet input, a serial input, a parallel input, a wireless interface , an Ethernet interface, a serial interface, a parallel interface, an Ethernet port, a serial port, and/or a parallel port. Furthermore, it should be noted that these data inputs (as well as the DS data sources discussed above) can provide data to data processing unit 14 in a wired or wireless manner and/or direct or indirect form. Likewise, the data processing unit 14 includes the necessary programs (and the data recording unit 10 includes the necessary internal components) to receive wired and/or wireless data input. In another preferred and non-limiting embodiment, the internal time source 24 will be in the form of a separate time reference that can be synchronized to some external locomotive or vehicle source.
    [033] In another preferred and non-limiting embodiment, the data is synchronized by multiple data entries using at least a portion of the time data (e.g., a dating or other time informational data) of the at least one data entry or DS data sources. For example, time data from a specific data entry can be used in data synchronization from another data entry (or multiple other data entries) to ensure complete and accurate synchronization across multiple data entries. In addition, time data from any of the DS data inputs or data sources, and/or the internal time source 24 discussed above, may be stored or recorded in or on the data logging unit 12. 0 data usage Time synchronization for multiple data inputs or DS data sources facilitates the ability to specify how data is retrieved, synchronized, or otherwise used.
    [034] In a preferred and non-limiting embodiment, and with continued reference to Figure 3, the independent time source 24 can be used to synchronize received data that has independent, external time data. For example, a data source can provide video data that is associated with time data from an independent time source (eg, a time source internal to a video camera or other device). To synchronize all or a portion of the data received by the data recording unit 10, the data processing unit 14 is programmed or configured to compare time data associated with one or more data sources to determine whether the various moments are synchronized. For example, the data processing unit 14 can determine that clocks or other time sources from one or more data sources are not in synchronization with each other or with the internal time source 24 of the data recording unit 10. In one embodiment Additional non-limiting, two or more data sources can be recorded on separate partitions of the storage device 16. In this example, the data recorded on the separate partitions can be synchronized using the internal time source 24. In addition, this information and data from Synchronization can be transmitted or distributed to other control systems or data files, such as an integrated train computer, a railway internal operations server, or some other remote system.
    [035] In a further preferred and non-limiting embodiment, and as illustrated in Figure 4, the data logger system 1 includes one or more video camera devices 28 (i.e., a video or visual data capture device) , which are configured to generate video data associated with the vehicle and/or surrounding areas or indoor or outdoor environment, and transmit at least a portion of this video data wirelessly and/or via wired connections. Such video data may include raw data, formatted data, pre-processed data, and the like. In that embodiment, the data processing unit 14 is programmed or configured to receive at least a portion of the video data from the video camera device 28, process at least a portion of that raw video data, and generate processed video data with based at least partially on the video data. Furthermore, at least a portion of such video data and/or processed video data is stored in storage device 16. In another preferred and non-limiting embodiment, storage device 16 is in the form of a solid state storage device, which is located within a shock and/or fireproof housing 18, which is, in turn, positioned within the data logger housing 12. In a preferred and non-limiting embodiment, the data processing unit 14 will include or will be based on a Linux logging application for a standard network camera.
    [036] In a preferred and non-limiting embodiment, and with continued reference to Figure 4, at least one video camera 28 may be an Internet Protocol (IP) camera, and the video data captured by the video camera 28 may transmitted to the data logger 10 wirelessly over a network connection. The video camera 28 and/or data recording unit 10 may include a wireless interface for transmitting and/or receiving data wirelessly. For example, a wireless Ethernet interface on data logger unit 10 can receive video data from video camera 28 over a network. In addition, the data logger unit 10 may include an Ethernet interface with which the video camera 28 (or other DS data source) is in wired communication. In some non-limiting embodiments, such video data may be saved to a partition of storage device 16 configured as network-enclosed storage. However, it will be appreciated that the connection can also be wired. In non-limiting embodiments, the network connection is either wired or wireless. In these embodiments, the wired connection can be used to transmit video data in the event that a network connection is lost, removed or unavailable. For example, a power outage can affect network devices such as routers and/or switches, and a wired connection can allow continuous transmission of video data despite these interruptions.
    [037] In a further preferred and non-limiting embodiment, and with reference to Figure 5, the storage device 16 includes at least a first storage device 30 in the form of at least one solid-state storage device, and at least one second storage device 32 which is in the form of at least one crash-consolidated memory. In a further preferred and non-limiting embodiment, the solid state storage device is a removable solid state storage device and the data processing unit 14 is configured to store all or part of the specific data set or certain information in its removable solid state storage device, such as from a DS data source of "accumulated data". Still, in this embodiment, the second storage device 32 is configured to store all or part of the specific crucial data or information from a crucial DS data source that is in communication with the data processing unit 14.
    [038] As illustrated in Figure 6, and in another preferred and non-limiting embodiment, the storage device 16 includes the first storage device 30 and the second storage device 32. However, in that embodiment, the first storage device 30 is in the form of at least one crash-consolidated memory 34, and the second storage device 32 is in the form of at least one crash-consolidated memory 36. In that embodiment, the data processing unit 14 is configured to transfer or initially store data on the first storage device 30, and at least a portion of this data is then cached on the second storage device 32. Such cached data may represent authenticated data, encrypted data, verified data, digitally signed data , specific data, crucial data, and/or dynamic data. Furthermore, in this embodiment, the second storage device 32 is configured for wired or wireless transmission of at least a portion of such cached data to at least one download device 38. Still, in this embodiment, the first storage device 30 and/or the second storage device 32 may be in the form of at least one solid state storage device. By using this caching methodology, cached data is more readily accessible and more easily (and quickly) downloaded to the download device 38.
    [039] Furthermore, according to another non-limiting realization, an arrangement that uses both a crash-consolidated memory 34 and a crash-uncommitted memory 36 allows cheap crash-uncommitted memory 36 to be used to record non-critical data. Additionally as explained above, the use of separate data storage devices 30, 32 can allow the most recent data to be cached in crash-consolidated memory 34, while non-recent data is continuously stored and overwritten in crash-uncommitted memory. 36. In these realizations, in the event of an accident, most recently recorded video data pertinent to the accident will be preserved in the consolidated crash storage device 32. The most current and/or latest video data can be determined by a storage capacity of the second storage device 32 and/or a predetermined or specific length of time (e.g. minutes and/or seconds of video data). Existing data in crash-consolidated memory 36 can be overwritten, in the order in which they were recorded, first out, using crash-consolidated memory 36 as a data stack or data buffer.
    [040] In a further preferred and non-limiting embodiment, the data logging unit 10 or other device in communication with the data logging unit 10 is programmed or configured to detect an event. This event may include, for example, an emergency lockout request, an indication or signal from a Positive Train Control System (PTC), a rapid deceleration, and/or an accelerometer-based detection of an impact or derailment, gyroscope and/or impact sensor data. In response to detecting an event, or receiving a signal or other indication that an event has occurred, the data processing unit 14 may continue to cache received data and prevent at least a portion of the data stored in the storage device. 16 is engraved over the top. For example, and with reference to Figure 6, in response to the occurrence of an event, the data logger unit 10 can prevent some or all of the data cached in a crash consolidated storage device 32 from being overwritten by newly overwritten data. received and may continue to cache the newly received data, until a maximum capacity of the crash consolidated storage device 32 is reached or a specified time.
    [041] Referring to Figure 7, and in another preferred and non-limiting embodiment, the data logger unit 10 includes a storage device 16 which may be crash-consolidated memory 34 and/or fire-resistant memory. In this embodiment, the power dissipation of the storage device 16 can be adjusted or suppressed based, at least partially, on a detected temperature of the storage device 16 and/or data logging unit 10. In particular, such detected temperature can be generated or derived from at least one temperature sensor 40 located in or within (or adjacent to) the data logging unit 10. In particular, and in a preferred and non-limiting embodiment, energy dissipation is suppressed as the temperature increases. Furthermore, in that embodiment, storage device 16 may be in the form of at least one solid-state storage device.
    [042] With continued reference to Figure 7, the power dissipation of storage device 16 can be suppressed in various ways to maintain or adjust the temperature below a specific or predetermined threshold. For example, energy can be dissipated by discarding non-crucial data, temporary buffering data without registering it to storage device 16, storing non-crucial data in at least one other storage device, and/or adjusting a flow to reduce the amount of non-critical data recorded in storage device 16. Data that is temporarily buffered rather than recorded in storage device 16 for which power dissipation is being suppressed or adjusted can be recorded to the storage device 16 at a later time when the temperature is lowered or otherwise reaches an acceptable level. It will be appreciated by those skilled in the art that the power dissipation of storage device 16 can be suppressed in various other ways in response to detecting a temperature that equals or exceeds a specific or predetermined threshold or maximum temperature.
    [043] Still, a further preferred and non-limiting embodiment is illustrated in Figure 8. In that embodiment, the data recording unit 10 includes at least one energy storage device 42. The energy storage device 42 may include, for example , one or more super capacitors, one or more batteries, or any other similar device that can store energy. The energy storage device 42 may allow the data recording unit 10 to continue operation after a main energy supply has been lost, removed or otherwise becomes unavailable.
