CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. provisional application No. 60/385,645 filed Jun. 4, 2002 the contents of which are incorporated by reference herein in their entirety.[0001]

BACKGROUND

The invention relates to integrated diagnostic, telemetry and recording systems for use in a locomotive.

Event recorders exist for use with locomotives. Such event recorders receive data corresponding to numerous parameters such as speed, acceleration, etc., from the locomotive control system over a communications channel (e.g., RS 422 interface). Upon the occurrence of an event the event recorder stores locomotive data in a memory module. An exemplary locomotive event recorder is produced by Electrodynamics, Inc.

Locomotive audio/video recording systems are also known in the art. An exemplary locomotive audio/video recording system is the RailView system available from Transportation Technology Group. In such audio/video recording systems, video data and optionally audio data are stored to a high capacity, memory device such as a floppy disk drive, hard disk drive or magnetic tape.

Another locomotive video system is disclosed in U.S. Pat. No. 5,978,718 for use in rail traffic control. For trains traveling on a route equipped with a wayside signaling system, the operating authority guides each train via wayside signal devices dispersed at various intervals throughout the length of the railway route. Though trains can be guided safely along unsignaled routes, wayside signaling systems are preferable, especially on heavily trafficked routes, as they can be used to guide trains even more safely and more quickly along such signaled routes with less distance between them. In the video system of the '718 patent, a rail vision system is employed to visually read signal aspect information from each wayside signal device of a wayside signaling system. The system can be configured to warn a train operator of the more restrictive signal aspects and impose brake application should the train operator fail to acknowledge the warning. The rail vision system includes a signal locating system and a rail navigation system. The rail navigation system determines the position that the train occupies on the railway track and provides the signal locating system with data as to the whereabouts of the upcoming wayside signal device relative to the position of the train. The signal locating system isolates upcoming wayside signal devices and reads the information therefrom as the train approaches. The signal locating system provides the information read therefrom to the rail navigation system. The rail navigation system can then warn the train operator of restrictive signal aspects, and should the train operator fail to acknowledge the warning, impose a brake application.

It should be noted that the foregoing background information is provided to assist the reader in understanding the instant invention. Accordingly, any terms used herein are not intended to be limited to any particular narrow interpretation unless specifically stated otherwise in this document.

There is therefore, a need in the railroad industry for a system that could inform the operator of the train, of the status wayside signaling system, and store and transmit information related to the wayside signaling and locomotive operating parameters and diagnostics without the aforementioned disadvantages. Specifically, it would be desirable to develop a system that can visually read the signal aspect information from each wayside signal device, and further monitor wayside and crossing status. Furthermore, such a system could monitor locomotive diagnostics and record important information at selected intervals for later evaluation. Finally, such a system could facilitate incident evaluation with communications enabling immediate link of gathered data to a remote operator.

SUMMARY

Disclosed herein in an exemplary embodiment is a video recorder system carried on-board a railroad locomotive for recording images relating to events of interest in a vicinity of the locomotive and transmitting the images to a location off-board of the locomotive, the system comprising: an audio/video system with a camera mounted on the locomotive for imaging an environment in a vicinity of the locomotive, the camera transmitting imaging data indicative of images acquired; and data storage on-board the locomotive in communication with the camera for storing the imaging data. The system also includes a processor on-board the locomotive in communication with the data storage for identifying and retrieving selected imaging data of interest from the data storage. Optionally the system may further include a wireless communication system on-board the locomotive in communication with said processor for transmitting signals associated with the selected imaging data of interest to a location off-board of the locomotive and receiving commands and information from off board the locomotive. The system also optionally includes: a plurality of sensors for gathering data regarding other parameters associated with the operation of the locomotive at the time of an event; and a navigation system operatively coupled with the management unit configured to transmit and receive commands instructions, and data to the management unit. The system may further include a the data storage device being a solid-state, non-volatile memory of sufficient storage capacity to provide long-term data storage of data and video data for a significant period of time associated with an event.

DETAILED DESCRIPTION OF AN EXEMPLARY EMBODIMENT

Disclosed herein is a locomotive video recorder and recording system comprising a combination of video technologies, wireless information systems, and locomotive transportation systems which enable configurable event based, image and parameter data recording, remote monitoring, and diagnostic services that aid in resolving various railroad transportation issues. Referring to FIG. 1, the locomotive video recorder and recording system shown generally as [0012] 5 comprises an on-board group of systems 200 and “off-board” systems 300. An event recorder functionality includes recording and transmitting relevant video, geographic data, and locomotive operating parameters to assist in resolving issues related to RR crossing accidents, train derailments, collisions, and wayside equipment inspection and maintenance. In addition, this video recorder and recording system 5 can be used to perform remote monitoring and diagnostics of track conditions, wayside equipment, and operator train management.
The data collection, processing, and wireless transmission provided by the locomotive wireless video recorder and recording system [0013] 5, enable a user to quickly respond to issues that occur in and around the many locomotives moving throughout a railroad network. Event data transmission may be configured to occur based on various locomotive conditions, geographic locations, and situations. In addition, event data may be either pulled (requested) or pushed (transmitted) from the locomotive. For example, data can be sent from a locomotive to an off-board data and monitoring center 310 based on selected operating conditions (e.g., emergency brake application), geographic location (e.g., in the vicinity of a railroad crossing), selected or derived operating areas of concern (e.g., high wheel slip or locomotive speed exceeding area limits), or time driven messages (e.g., sent once a day). An off-board central monitoring and data center 310 may also request and retrieve the data from specific locomotives on demand.
Wireless communication connectivity also enables the off-board data and [0014] monitoring center 310 to provide additional functions including remote monitoring and diagnostics of the system and remote configuration management of the mobile on-board systems 200.
FIG. 2 is a block diagram depicting an exemplary on [0015] board system 200 with integrated diagnostic, telemetry, and video recording system 5 hereinafter denoted system 5. The system 5 includes a management unit or processor, hereinafter denoted management unit 10, which provides command and control of various interfaces and processes as may be accomplished. In addition, the management unit 10 may further include diagnostics and event recording capabilities. Event recording, for example, determines selected parameters to observe, evaluate, and if desired save or record.
The [0016] management unit 10 may include, without limitation, a computer or processor, logic, memory, storage, registers, timing, interrupts, and the input/output signal interfaces as required to perform the processing prescribed herein. The management unit 10 receives inputs from various sensors and systems and generates output signals thereto. FIG. 3 depicts the top-level block diagram of the processing functions and data flow of the integrated diagnostic, telemetry and recording system 5. It will be appreciated that while in an exemplary embodiment most processing is described as resident in the management unit 10, such a configuration is illustrative only. Various processing and functionality may be distributed among one or more system elements without deviating from the scope and breadth of the claims.
In an exemplary embodiment, the [0017] management unit 10 performs or facilitates the following processes:
Collection of data from various inputs (video, GPS, locomotive data); [0018]
Processing of data; [0019]
Recordation and Storage of data; [0020]
Logical computations to determine appropriate system actions (send data, file management, video controls); [0021]
Control of video equipment (on/off, time and location activation, image quality settings, etc); [0022]
Association of audio/video data with parameter and event data; [0023]
Interfaces with the wireless network; [0024]
Processes commands from the off-board data and monitoring center; and [0025]
System diagnostics and health status. [0026]
The event recording capability of the [0027] management unit 10 receives locomotive data from the locomotive system 18 including, but not limited to acceleration, speed, direction, braking conditions, wheel slip and the like. The management unit 10 and/or a data storage 12 may continually direct and facilitate the storage of various locomotive data in the data storage 12 on a first-in, first-out basis. This allows the system to capture locomotive data leading up to an event. Alternatively, the management unit 10 may initiate storing locomotive data in the data storage 12 upon detection of an event or via operator control on-board the locomotive or from a off-board data and monitoring center 310. Detection of an event is performed using known techniques (e.g., vehicle sensors, such as accelerometers, speed sensors, locomotive operational sensors, and the like).
The [0028] management unit 10 in performing the abovementioned processes may utilize various signals along with and in comparison to a database of stored information (described below). The database 32 may be employed to facilitate correlation of selected data with a selected or specified events. Moreover, the database 32 may be employed to identify a type of event or events and a selected set of images, operational parameter, or environmental parameter data that is preferably associated or relevant to such an event. The database 32 may be utilized for example, to determine not only the position that the train occupies on the railway track but also the location relative to the position of the train of an upcoming target of interest or desired input for event and video recording. For example, a wayside signal device, crossing, bridge, curve in the track, and the like. This information may be used to determine gating of sensors, or the cameras 142 of the audio/video system 14, for example, in an exemplary embodiment, the management unit 10 determines where the train is located in relation to the track route location data stored in the abovementioned onboard database 32. Through such processing, the geographical coordinates of the train may be compared with the abovementioned database information to determine not only on which track the train is traveling but also the particular segment and position that the train occupies on that track.
When the [0029] management unit 10 has determined or established the expected location and position of a desired input, e.g., upcoming crossing, wayside signaling device, and the like, the management unit 10 may optionally direct the audio video system 14 and the sensing means 142, e.g., camera or particular camera to focus on the upcoming desired input, for example, an up coming wayside signal device. Additionally, the management unit 10 may direct recordation of selected parameters related to the operation of the locomotive or environmental parameters and data. These data may then readily be associated with selected video data to provide detailed insight into the operation of the locomotive and past events.
In another exemplary embodiment, the [0030] management unit 10 may be employed to facilitate operation of an on-board system diagnostics and health monitoring for the system 5, or components thereof. For example, in an exemplary embodiment, the management unit 10, data storage 12 and a communication system 50 may be employed to detect, store, and transmit to the off-board central data center 310 relevant operating system parameters and information such as diagnostics and/or failure of the management unit 10, data storage or other components of the system 5. The diagnostics may further identify component status, and failure or inoperability including, but not limited to, loss of power loss or operation of the audio/video system 14 and components thereof, loss of imaging data, time, and location of failures.
The on-[0031] board systems 200 may also include data storage 12. The data storage 12 is configured to exhibit sufficient capacity to capture and record data to facilitate performance of the functions disclosed herein. The data storage 12 provides of suitable storage capacity, such as 2 gigabytes of memory in a exemplary embodiment. In one embodiment, the data storage 12 uses flash memory. Data storage 12 may also include non-volatile random access memory (RAM). Moreover, as part of the data storage 12, in one configuration, the management unit 10 may include non-volatile memory for storage of diagnostic and status data.
As shown in FIG. 2, the [0032] data storage 12 includes a housing 13, with the housing preferably protecting a data storage device 12 against mechanical and electrical damage during an event (e.g., selected locations, operating conditions, or an accident involving the locomotive) to preserve data held in data storage device 12. The data storage device 12 is preferably a solid-state, non-volatile memory of sufficient storage capacity to provide long-term data storage of the locomotive data, environmental data, video data and audio data for a significant period of time (e.g., 15 minutes) associated with a selected event. Once again, it will be appreciated that while the data storage device 12 are described herein as separate entities from the management unit 10 either or both could be configured to be separate or combined, as well as being combined with other elements of the system 5 disclosed herein. Additionally it should be appreciated the while a particular partitioning of the processing and functionality is disclosed herein, such partitioning is illustrative only to facilitate disclosure. Many other arrangements and partitions of like functionality may now readily be apparent.
The [0033] data storage 12 may also utilized to store a database 32 composed of a variety of information that may be used in conjunction with data and parameters acquired. In particular, the database may be employed to correlate acquired data with a selected event or events. For example, the database may be employed in cooperation with a navigation system 20, for example, a Global Positioning System (GPS) to facilitate position determination, localizing, and determination or evaluation for gating of data and video recording functions as a function of position, location, time, wayside status, and the like, as well as combinations including at least one of the foregoing. The database may include data including, but not limited to: (i) the locations of railway track routes, and track mapping (ii) the locations and orientations of curves and switches in those railway track routes, (iii) the location of each wayside device on each railway track route, (iv) the type of each wayside device (e.g., crossing gates, switches, signals, background shape, number of lights, possible color combinations), (v) the direction which each wayside device points (e.g., eastbound or westbound, etc.) and the particular track to which each wayside device relates (e.g., main track or siding), (vi) the position of each wayside device with respect to the particular track and the direction which the train is traveling (e.g., to the right, left, overhead), (vii) the distance from each wayside device at which imaging of the object should start, and (viii) the operation of the wayside device (e.g., lights are operating, horn or bell is operating, the crossing gate arms are moving etc.). As explained below, the database may also feature data pertaining to (x) the location of every highway or other type of crossing on all relevant railway track routes and (xi) the distance from each crossing at which imaging should start. This location data is pegged to the identity of each railway route typically by reference to milepost distances. Moreover, the database may include various operational and environmental parameters associated with a various types of events. The database 32 may be employed to identify a for particular type of event, the environmental and operational parameter data that would be relevant to a selected event.
Coupled to the [0034] data storage 12, and optionally to the management unit 10 is an audio/video system 14. The audio/video system 14 generates audio data and video data that is either stored directly in the data storage 12 or stored in coordination with operational and environmental parameter data available in the system 5. In an exemplary embodiment, the audio/video system 14 acquires digital audio and digital video information. However, optionally analog equipment may be employed. The audio/video system 14 includes one or more cameras and/or microphones directed as desired to obtain desired video and audio information. The audio/video system 14 includes a input or sensing means 142 that can for example, take the form of any one of a variety of known cameras and/or microphones including the types of cameras that feature aiming and zooming mechanisms that can be externally controlled to aim the camera at an upcoming object with high clarity even at relatively long distances. Further, in an exemplary embodiment, a sensing means 142 with control of lighting effects, resolution, volume control for audio, frequency of imaging, data storage, and information concerning audio/video system parameters may be utilized. The sensing means 142 e.g., camera and/or microphone, is used to generate a video signal indicative of an image of the object, such as an upcoming wayside device, crossing, or track conditions onto which it is focused. Additionally, the audio/video system 14 and more particularly the sensing means 142 may further take advantage of video technologies that facilitate low/no light image collection or collection of specific images. For example infrared and detection of specific images, e.g., flashing red crossing lights.
The audio/[0035] video system 14 may also include a processing means 144 that may take the form of any one of several types of hardware and software embodiments known in the signal processing art for handling and processing the captured data. Using any number of well established signal processing techniques, the processing means 144 is to be used to process the video signals generated by the sensing means e.g., camera(s) and/or microphones 142 so that the upcoming wayside signal device, the signal aspect information therefrom, crossing, or track conditions, is rendered discernable. The particular techniques and hardware/software implementation selected for the processing means 144 is well known and a function of desired capabilities, characteristics, cost, and the like.
The audio/video signal generated by the sensing means [0036] 142 e.g., camera and/or microphone may be processed by the processing means 144 in an attempt to render the upcoming desired input, as well as any information appearing thereabout, discernable. Further, the processing may include a determination of characteristics of the upcoming desire input, for example, particular signal information, crossing status or obstruction, crossing gate status, crossing gate light status, crossing gate audible warning, and the like.
The sensing means [0037] 142 e.g., camera(s) and/or microphone(s) may be directed out the front of the locomotive. Additionally, sensing means 142 may be directed to either side, or to the rear of the locomotive or multiple cameras may be used to capture images from multiple areas. Such a configuration preserves a visual record of the wayside signaling information, crossing status, and items on or near the track in the event of a mishap. Moreover, and in conjunction with the event and data recording capability of the management unit 10, the video data may be captured and stored in a universal time-tagged manner with other locomotive parameters, such as diagnostics, and locomotive operational characteristics and parameters to facilitate incident investigation and operator evaluation. Additionally, one or more microphone(s) may be employed to record audio such as, wayside equipment lights, sound and operation, locomotive operational sounds, or the application of the locomotive horn.
The audio/[0038] video system 14 may optionally feature a display unit 146 to show the train operator a wide variety of data intelligence gathered or information to facilitate operation or diagnostics of the locomotive. The display unit 146 may feature selected video data and operational parameters including, but not limited to, wayside signal aspects, speed, power and the like. The display unit 146 may also feature a graphical display used to provide the train operator with the actual video image generated by the camera(s) 142. It may also be used to display supplemental information such as the profile of the upcoming portion of railway track, the estimated distance required to brake the train, the territorial coverage of the railway operating authority or other data, and the like.
The audio/[0039] video system 14 may also be used to detect and react to obstructions on the railway track. This configuration would assist operators of trains that travel along railway routes that intersect with highways or other types of railway track crossings.
The video data and audio data (if used) may be stored continuously in the [0040] data storage 12 on a first-in, first-out basis employing a continuous looping approach. Upon occurrence of an event, the audio/video data is preserved in data storage 12. This enhances the ability to determine the cause of an event. The capacity of the data storage 12 can be increased as required to store additional audio/video data or locomotive data. Again, this allows the management unit to direct the recording of a predetermined amount of video/audio data leading up to an event. Alternatively, the audio/video system 14 may be configured to initiate imaging/observing, and transmitting video/audio data to the data storage 12 for recordation upon detection of an event, selected event, or based upon operational and environment parameters and the like.
By collecting locomotive data, audio/video data, and environmental data, and the like in [0041] data storage 12, the integrated diagnostic, telemetry and video recording system 5 facilitates analysis of locomotive events. The addition of environmental and locomotive operating parameter data stored in the same data storage 12 simplifies configuration of the system 5, integration, and further enhances the ability to investigate locomotive events. Moreover, as disclosed herein, linking the storage and event or data recording capabilities as disclosed with a remotely configurable communications system 50 further facilitates data capture, analysis and incident investigation as may be directed by an off-board data and monitoring center 310.
Continuing now with FIGS. 1 and 2, the integrated diagnostic, telemetry and video recording system may further include a [0042] communications system 50 integrated with data storage 12 and optionally the audio/video system 14 and management unit 10. In an exemplary embodiment, the communications system 50 includes multiple communications systems employed as may facilitate a particular communication or environment including, but not limited to wireless satellite communications system, a cellular communications system, radio, private networks, a Wireless Local Area Network WLAN, and the like, as well as combinations including at least one of the foregoing. In an exemplary embodiments the wireless communication system may be employed to transmit image data, environmental and operational parameter data corresponding to a selected event or events to the off-board data and monitoring center 300.
The [0043] wireless communication system 50 may comprise an onboard receiver 52 and transmitter 54. The wireless communication system 50 provides a means to transmit the data between locomotives and from the locomotive to an off-board processing center 300. Optionally, the wireless communications system may be employed for communication to the system 5 for diagnostics, data downloads, uploads and the like. Additionally, the wireless communication system 50 provides a means to receive commands and requests from the off-board processing center 300. For example commands pertaining to transmission protocol, channel, transmission format, transmission timer, packet size, frequency, and the like as well as combinations including at least one of the foregoing. Moreover, data may also be retrieved from the locomotive mounted management unit 10 via manual (wired) interfaces and downloads to another computer or even management unit 10 memory removal.
Continuing once again with FIGS. 1 and 2, the integrated diagnostic, telemetry and video recording system [0044] 5 may further include a navigation system 20. The navigation system 20 may be employed to determine the position of the train/locomotive occupies on the globe. In an exemplary embodiment, the navigational system takes the form of a Global Positioning System hereinafter GPS, which can receive signals and determine global coordinates, such as latitude and longitude, directional information, velocity and time. The GPS provides geographic, movement, and time data to the management unit 10 to facilitate correlation of selected image, operational and environmental parameter data with a chronological time and/or geographic location. Time tag data may include, but not be limited to, chronological time, time of transmission and the like. Geographic data may include, but not be limited to, latitude, longitude, velocities and the like. In an exemplary embodiment, the GPS system includes, but is not limited to a locomotive mounted antenna and receiver/computer that processes signals from low earth orbiting satellites to provide the abovementioned data.
In an exemplary embodiment, the GPS receiver should preferably be accurate enough to identify a curve or a switch on which the train is located. Thus, the data that the GPS receiver itself may provide may only be an approximation of the exact position of the train. The GPS may further be coupled with other navigational aids to further facilitate accurate position location and determination. The GPS information may further be coupled with the stored information about the track to further facilitate a determination of where the locomotive, (and thereby the train) is on the track relative to fixed waypoints or entities, for example a wayside signaling device or crossing. [0045]
The [0046] locomotive system 30 includes, but is not limited to, various sensor and data sources that provide inputs to the data storage 12 and/or management unit 10. One source is the locomotive control system that provides data about the operational performance and status of the locomotive. For example, data on power commands, engine speed, locomotive speed, traction feedback, pneumatic brakes, brake pressures, dynamic braking, load, throttle, operating faults, ambient temperature, commanded parameters and the like. Another data source is the locomotive “trainlines”—these (discrete) signals run between locomotives in a train and provide operation status of the locomotive. For example, the “trainlines” include data on operator's power/brake command, direction call, power mode, and the like. Moreover, data can also be collected directly from various locomotive and environmental sensors 40, control circuits and devices, e.g., track geometry monitors, smoke and fire detectors, chemical or fuel detectors, engine on relay and emergency brake relay or other data collection devices, such the data event recorder, locomotives horn and bell indication and the like. Other environmental and operational parameters that may be observed and recorded may include but not be limited to: weather conditions, e.g., rain, snow, fog, and the like; horn and lights, track conditions, track topology, elevation direction and heading.
Returning to FIGS. 1 and 2, the off-board [0047] data processing center 300 interfaces with the wireless communication system and manages the files and commands to and from the locomotives. The off-board data processing center 300 employs a wireless communications system 320 to interface with on-board systems. The wireless communication system 320 may include but not be limited to a transmitter and receiver for satellite communications, radio, cellular, and the like, as well as combinations including at least one of the foregoing. The off-board data processing center 300 processes the data into valuable data for the users. A monitoring and diagnostic service center (MDSC) 310 processes the data collected by the system and provides the event replay services and diagnostic recommendations. The MDSC also uses the system to perform remote monitoring of the locomotive and surrounding elements such as the rail, signaling, and crossing equipment. The MDSC 310 with the communications system 320 transmits request to the on board systems 200 for selection of desired images, environmental and operational parameter data. Advantageously, the system may be employed to select specified data to be stored and/or transmitted to the off-board MDSC 310 under selected conditions such as when the locomotive approaches or reaches a desired location, wayside signaling device, at a specified time, and the like. The MDSC 310 may also be employed to remotely modify the configuration of the onboard communications system 50 The MDSC also monitors the health of the audio/video system 14, locomotive system 30, navigational system 20, and a wireless communications system 50 and performs required maintenance (e.g., hardware and software version tracking). Raw data and diagnostic recommendations are exchanged with various customers by the MDSC via web pages or business-to-business file transfers.
The [0048] management unit 10, data storage 12, audio/video recording system 14, communications system 50 navigation system 20, locomotive control system 18 and environmental sensors 40 may be powered during normal operation from a locomotive power supply V_L. The source of locomotive power supply V_Lmay be a generator driven by the locomotives engine. The management unit 10, data storage 12, audio/video recording system 14, communications system 50, and navigation system 20, may optionally include auxiliary power supplies such as batteries 34. During failure or disruption of the locomotive power supply V_L, auxiliary power supplies 34 are utilized to facilitate continued operation. Alternatively, instead of separate auxiliary power supplies for each component, an auxiliary power supply could supplement locomotive power supply V_Lin the event of a failure or disruption locomotive power supply V_Lto supply selected components of the system 5. In an exemplary embodiment, the data storage 12 and audio/video recording system 14 may be powered with auxiliary power supplies 34. Optionally, the management unit 10, communications system 50 navigation system 20, locomotive control system 18 and environmental sensors 40 may also be powered with one or more auxiliary power supplies 34.
It will be understood that a person skilled in the art may make modifications to the preferred embodiment shown herein within the scope and intent of the claims. While the present invention has been described as carried out in a specific embodiment thereof, it is not intended to be limited thereby but is intended to cover the invention broadly within the scope and spirit of the claims.
