Abstract
A system to determine a location of rolling stock, the system including a transmitting device proximate a surface on which a rolling stock rides upon, a signal comprising at least one of location data and unique identification data of the transmitting device that is emitted from the transmitting device only when the rolling stock is proximate the transmitting device, and a receiving device that receives the signal.
Description
- This invention relates to a rail and train system and, more particularly, to a system and method for acquiring an exact position of rolling stock.
- Fixed rail transportation systems that include one or more a rail vehicles traveling over spaced apart rails of a railway track have been an efficient way of moving cargo and people from one geographical location to another. In densely populated countries and countries having an unimproved road transportation systems, rail vehicles may be the primary means for moving people and cargo. Accordingly, there are probably millions of miles of railroad track throughout the world that need to be maintained to provide safe rail transportation.
- As rail and train systems evolve into smarter computer based platforms, the need to know a precise location of a train, or rolling stock, is appreciated. This need is especially needed when the rolling stock is in remote areas where traditional location detecting systems may not be accurate and knowing whether or not such systems are accurate or not is not readily determinable. For example, for some smarter computer based platforms even though GPS is available, a secondary independent system is also required so as to provide the required data integrity to insure that safety critical decisions are made.
- Various secondary systems have been proposed, but such systems may be susceptible to malfunctions and/or failures wherein knowing that a malfunction/failure occurred may not be readily determined. Because of the vastness of the network of railway tracks, a cost effective secondary system would be appreciated where the cost to install and maintain the system is preferred.
- This invention is directed towards a system and method for acquiring an exact position of rolling stock. Towards this end, a system to determine a location of rolling stock is disclosed. The system includes a transmitting device proximate a surface on which a rolling stock rides upon. A signal is also disclosed. The signal has location data and/or unique identification data of the transmitting device. The signal is emitted from the transmitting device when the rolling stock is proximate the transmitting device. A receiving device that receives the signal is also disclosed.
- In another exemplary embodiment a system for determining a location of a train is disclosed. This system includes a sensor proximate a railroad rail, a transmitting device in communication with the sensor, and a signal. The signal has location data and/or unique identification data of the transmitting device which is emitted from the transmitting device when the sensor is activated. A receiving device that receives the signal is also disclosed.
- In yet another exemplary embodiment a method for autonomously determining a location of a moving vehicle is disclosed. The method includes activating a transmitting device that transmits a signal when the vehicle is proximate the transmitting device. Upon activating the transmitting device, the signal is emitted. The signal has location data and/or unique identification data of the transmitting device. The signal is received by a receiving device located on the vehicle or proximate the transmitting device so as to determine where the moving vehicle is located.
- A more particular description of the invention briefly described above will be rendered by reference to specific embodiments thereof that are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered to be limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
-
FIG. 1 depicts a prior art illustration of a rail attached to a rail tie; -
FIG. 2 depicts an exemplary embodiment of the present invention transmitting data; and -
FIG. 3 depicts an exemplary embodiment of a method of the present invention. - Reference will now be made in detail to the embodiments consistent with the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numerals used throughout the drawings refer to the same or like parts. Though the present invention is directed towards a system, method and computerized method for acquiring an exact position of rolling stock, those skilled in the art will recognize how the present invention can be utilized in other embodiments than just with rolling stock. Furthermore, acquiring an exact position of rolling stock may also involve detecting the position, direction traveled, velocity, acceleration, and length of the rolling stock.
-
FIG. 1 depicts a prior art illustration of a railway rail detached to a railway tie. The railway can also be viewed as the surface upon which the train, rolling stock, and/or vehicle rides upon. Towards this end, even though a railway is disclosed, those skilled in the art will readily recognize that the present invention may be utilized with other surfaces. As illustrated, therail 10 and thetie 12 are separated by ashoe plate 14. Therail 10 andshoe plate 14 are then secured to thetie 12 by rail spike(s) 16. -
FIG. 2 depicts the present invention transmitting data. As illustrated, asensing device 20, such as a piezo electric pulse generator membrane, is positioned underneath therail 10 and between theshoe plate 14 and thetie 12. Atransmitter 24, or transmitting device, such as a RF transmitter, is proximate themembrane 20. For example in an exemplary embodiment, thetransmitter 24 is embedded and/or bored into therailroad tie 12. In another exemplary embodiment, thetransmitter 24 is positioned within the bed adjacent to therailroad tie 12. Themembrane 20 may either be directly connected 23 to the transmitter and/or in another exemplary embodiment, a wireless communication network may be available to allow themembrane 20 to communicate with thetransmitter 24. - Though a RF transmitter is discussed above, those skilled in the art will readily recognize that other forms of communication equipment may be used in the present invention wherein the
signal 26 emitted is not RF. For example, in an exemplary embodiment, Bluetooth technology may be utilized. In another exemplary embodiment, a combination of technologies may be used, such as RF and Bluetooth. - A
receiving device train 31 or at a wayside mounteddevice 33 close to thetransmitter 24. In an exemplary embodiment, as thewheels 22 of thelocomotive 31, moving stock, vehicle, and/or train, passes over therail 10 that has themembrane 20 beneath it, the compressive force exerted by the weight of thetrain 31 activates themembrane 20 wherein an electrical pulse is sent from themembrane 20 to thetransmitter 24. Prior to receiving the electrical pulse, thetransmitter 24 is passive. In other words, thetransmitter 24 is not transmitting. Upon receiving a pulse from themembrane 20, thetransmitter 24 emits asignal 26, which contains milestone position data, or unique position data if thetransmitter 24 is confined to a certain known location. For example, if the present invention is used within a rail yard, or known location, unique yard position data is transmitted from thetransmitter 24. - Thus, if used within a rail yard, in an exemplary embodiment, then the unique yard position data is transmitted to the wayside mounted
receiver 28. Whereas, if the present invention is used along a railway network, milestone, or milepost, position data is transmitted back to the train, more than likely the locomotive, where thereceiver 30 is located. Though the wayside mountedreceiver 28 is discussed above as being located within a rail yard, those skilled in the art, however, will also recognize that wayside mountedreceivers 28 may also be used within a railway network so as to provide train location data to awayside device 33 for use in performing a defined function. - In operation, when used in a rail network where the
locomotive 31 may need to acquire real time accurate train position data, the present invention with autonomously provide milepost data whenever thewheels 22 of atrain 31 passes over the present invention. Thetrain 31 is then able to pass off this milepost data to its systems and/or sub-systems that require such information. To insure reliability, redundancy, sequence numbers, and/or source data bits, built in tests (BITs) may also be added for improved data integrity as needed for safety critical decisions that utilizes position data, it is important that the integrity of the position data be commensurable to the hazard risk associated with the use of the position data. - When the present invention is installed within a rail yard, or hump yard, the present invention will autonomously generate a
signal 26 encoded with specific yard position data whenever thewheel 22 of rollingstock 31 passes over it. The wayside mountedreceiver 28 located in the yard will acquire the position data and then pass it along to yard based systems that require such information and can derive rolling stock position. The use of multiple exemplary examples of the present invention in a network environment in combination will allow the derivation of rolling stock movement direction, velocity, acceleration and/or length of the rolling stock. As discussed above, to insure reliability, redundancy, sequence numbers, and/or source data bits, built in tests (BITs) may also be added for improved data integrity as needed for safety critical decisions that utilizes position data. It is important that the integrity of the position data be commensurable to the hazard risk associated with the use of the position data. - Should an element of the present invention fail, fault detection may be accomplished by the present invention when in a networked configuration. The networked configuration can be accomplished in a closed location, such as a hump and/or rail yard, or the network can be formed within a railway network; for example, the railway network that covers the United States.
- In an exemplary embodiment, each transmitter is considered a node within the networked configuration. The
transmitter 24 andreceiver transmitter 24 fail, as an individual node in a networked system, wherein an improper signal is emitted, then the receiver/network will be able to detect the improper signal by reading nodes, other transmitters, before and after the node that failed. Thus if a transmitter is not transmitting proper or reasonable data, the present network of invention nodes in combination with network intelligence would know of this occurrence and would be able to report that information for future repair or invoke fail-safe or degraded modes of operation. -
FIG. 3 depicts an exemplary embodiment of a method of the present invention. As illustrated, the method provides for activating a transmitting device that transmits a signal when the vehicle, rolling stock, or train, is proximate the transmitting device,step 40. Upon activating the transmitting device, the signal emitted has information, or data, pertaining to location data and/or unique identification data of the transmitting device,step 42. The signal is received at a location so as to determine where the moving vehicle is located,step 44. As disclosed previously the location where the signal is received may include vehicle and/or receiving device proximate the transmitting device. - While the invention has been described in what is presently considered to be a preferred embodiment, many variations and modifications will become apparent to those skilled in the art. Accordingly, it is intended that the invention not be limited to the specific illustrative embodiment but be interpreted within the full spirit and scope of the appended claims.
