Device, System, and Method for Monitoring a Distance between Rail Cars during Coupling
Described are a device, system, and method for monitoring a distance between a first rail car and a second rail car during coupling. The device includes a fastener configured to affix the device to the first rail car and a distance sensor configured to detect the distance between the first rail car and the second rail car in a direction away from an end of the first rail car and toward an end of the second rail car. The device also includes a power source and a data connector to communicatively connect the device to a remote processor. The device further includes a local processor programmed or configured to repeatedly receive distance data from the distance sensor of the distance between the first rail car and the second rail car and communicate the distance data to the remote processor.
The present disclosure relates to train operation and, more particularly, to monitoring and controlling a distance between train vehicles during coupling procedures.
Technical ConsiderationsTrain coupling involves the movement of one or more rail cars (e.g., locomotives, passenger vehicles, cargo vehicles, etc.) along a track to connect two rail cars using couplers. Present coupling methods involve having an individual positioned in view of the coupling task relaying information with a voice radio to inform a train operator of the distance between the train vehicles being coupled. This can be imprecise and unsafe due to factors related to the individual observing the coupling move, such as distractions, radio communication issues, being incorrect about the estimated distance they relay to the train operator, and/or the like. Furthermore, there may be environmental hazards that increase the difficulty of manually monitoring the coupling process, including darkness, fog, snowy or icy conditions, windy conditions, uneven terrain surrounding the track, and/or the like. Additionally, there is an unavoidable lag time associated with one person observing and reporting the coupling status while another person listens and controls the movement, and such manual observation and reporting does not get recorded and is not reviewable if a coupling accident were to occur.
Accordingly, there is a need in the art for a device, system, and method of coupling without the requirement of physical human observation and reporting at the point of train vehicle coupling. Moreover, there is a need for a technical solution to provide more precise and immediate distance and movement feedback during coupling, to reduce lag time, reduce error, promote automation, and create a verifiable and reviewable data log.

These and other features and characteristics of the present disclosure, as well as the methods of operation and functions of the related elements of structures and the combination of parts and economies of manufacture, will become more apparent upon consideration of the following description, and the appended claims with reference to the accompanying drawings, all of which form a part of this specification, wherein like reference numerals designate corresponding parts in the various figures. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended as a definition of the limits of the disclosure. As used in the specification and the claims, the singular forms of “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.
These and other features of the present disclosure will become more apparent from the following description in which reference is made to the appended drawings wherein:
Various non-limiting examples will now be described with reference to the accompanying figures where like reference numbers correspond to like or functionally equivalent elements.
For purposes of the description hereinafter, the terms “end,” “upper,” “lower,” “right,” “left,” “vertical,” “horizontal,” “top,” “bottom,” “lateral,” “longitudinal,” and derivatives thereof shall relate to the example(s) as oriented in the drawing figures. However, it is to be understood that the example(s) may assume various alternative variations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific example(s) illustrated in the attached drawings, and described in the following specification, are simply exemplary examples or aspects of the disclosure. Hence, the specific examples or aspects disclosed herein are not to be construed as limiting. Also, it should be understood that any numerical range recited herein is intended to include all sub-ranges subsumed therein. For example, a range of 1 to 10 is intended to include all sub-ranges between (and including) the recited minimum value of 1 and the recited maximum value of 10, that is, having a minimum value equal to or greater than 1 and a maximum value of equal to or less than 10.
As used herein, the terms “communication” and “communicate” refer to the receipt or transfer of one or more signals, messages, commands, or other type of data. For one unit (e.g., any device, system, or component thereof) to be in communication with another unit means that the one unit is able to directly or indirectly receive data from and/or transmit data to the other unit. This may refer to a direct or indirect connection that is wired and/or wireless in nature. Additionally, two units may be in communication with each other even though the data transmitted may be modified, processed, relayed, and/or routed between the first and second unit. For example, a first unit may be in communication with a second unit even though the first unit passively receives data and does not actively transmit data to the second unit. As another example, a first unit may be in communication with a second unit if an intermediary unit processes data from one unit and transmits processed data to the second unit. As another example, a first unit may be in communication with a second unit if an intermediary unit processes data from one unit and transmits processed data to the second unit. It will be appreciated that numerous other arrangements are possible. Any known electronic communication protocols and/or algorithms may 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, Global System for Mobile Communications (GSM), and/or the like.
As used herein, the term “mobile device” may refer to one or more portable electronic devices configured to communicate with one or more networks. As an example, a mobile device may include a cellular phone (e.g., a smartphone or standard cellular phone), a portable computer (e.g., a tablet computer, a laptop computer, etc.), a wearable device (e.g., a watch, pair of glasses, lens, clothing, and/or the like), a personal digital assistant (PDA), and/or other like devices.
As used herein, the term “server” may refer to or include one or more processors or computers, storage devices, or similar computer arrangements that are operated by or facilitate communication and processing for multiple parties in a network environment, such as the internet. In some non-limiting embodiments, communication may be facilitated over one or more public or private network environments and that various other arrangements are possible. Further, multiple computers, e.g., servers, or other computerized devices, e.g., mobile devices, directly or indirectly communicating in the network environment may constitute a system, such as a remote train and drone control system. Reference to a server or a processor, as used herein, may refer to a previously-recited server and/or processor that is recited as performing a previous step or function, a different server and/or processor, and/or a combination of servers and/or processors. For example, as used in the specification and the claims, a first server and/or a first processor that is recited as performing a first step or function may refer to the same or different server and/or a processor recited as performing a second step or function.
In non-limiting embodiments or aspects of the present disclosure, provided are a device, system, and method for monitoring a distance between a first rail car and a second rail car during coupling. Described non-limiting embodiments or aspects improve over prior art systems by increasing the precision of proximity detection between two coupling train vehicles, as well as providing for closed-loop automation of train coupling processes by using distance data feedback to control locomotion and rail car movement. Described non-limiting embodiments or aspects further improve over prior art systems by providing for traceability and verifiability of historic coupling procedures, by generating logs of such procedures based on distance data, time of day, operator identifiers, train identifiers, track location, and/or the like—thereby providing analyzable metrics of successful couplings and failed couplings, which can further improve the algorithms used in closed-loop automation. Moreover, the removal of personnel at the coupling site improves over prior art systems by eliminating dangers inherent to track bystanders, and it further improves on the reliability of distance reporting, avoiding biases present in physical observation. By communicatively connecting a distance monitoring device with one or more remote processors (e.g., a locomotive computing device, a mobile device associated with a locomotive operator, a back office server, and/or the like), interoperability is improved while allowing for remote controlling and viewing of coupling processes. These advantages, among others, are further illustrated in the detailed description below.

With further reference to the foregoing figures, remote processors (e.g., train computing devices, remote controllers, etc.) may be manually operated and controlled by personnel to monitor and control rail car coupling processes. Such remote processors may include or be communicatively connected to a display to provide visual feedback of the coupling process. In arrangements where the distance monitoring device and/or distance sensor includes a camera configured to generate video/image data, the video/image data may be communicated to the display of the remote processor for viewing by personnel. The video/image data may allow the personnel to use a control interface of the remote processor (e.g., buttons, keyboard/mouse, levers, touchscreen, and/or the like) to control the movement of one or more rail cars and complete a coupling process. Remote processors may also assist with control of the train actions and may be partially or fully automated. It will be appreciated that many configurations are possible.
