Abstract

A remote control system (10) for a locomotive (16) includes a sensor (e.g. 15) on-board the locomotive for providing locomotive information. The system also includes a transmitter (13) for transmitting the locomotive information from the locomotive to an operator control unit (OCU) (12) off-board the locomotive. A graphical display (24) is associated with the OCU for displaying the locomotive information in a graphical format to an operator of the OCU. A locomotive control unit (LCU) (14) in communication with the OCU is operable to control the locomotive in response to a manipulation of the OCU by the operator.

Claims

1. A remote control system for a locomotive comprising:

a sensor on-board a locomotive and providing locomotive information;

a transmitter transmitting the locomotive information from the locomotive to an operator control unit (OCU) off-board the locomotive;

a graphical display associated with the OCU for displaying the locomotive information in a graphical format to an operator of the OCU; and

a locomotive control unit (LCU) in communication with the OCU and operable to control the locomotive in response to a manipulation of the OCU by the operator.

2. The system of claim 1, wherein the sensor comprises a location determination device for providing locomotive information comprising a location of the locomotive.

3. The system of claim 2, further comprising a track data base representative of a track layout in a railyard in communication with the OCU to allow the OCU to graphically display the location of the locomotive in the railyard relative to the track layout.

4. The system of claim 3, when used to control a plurality of locomotives in a railyard, each locomotive having a unique identifier, the system comprising a plurality of sensors for determining a respective location of each of the locomotives, and a transmitter on the OCU for addressing and communicating with a selected one of the locomotives for controlling movement of the selected one of the locomotives, with the OCU displaying the respective location of the selected one of the locomotives being controlled.

5. The system of claim 4, wherein the OCU displays the respective locations of other locomotives in the railyard different from the selected one.

6. The system of claim 2, wherein the location determination device comprises a GPS receiver.

7. The system of claim 2, wherein the location determination device comprises a transponder reader.

8. The system of claim 7, wherein the transponder reader comprises an automatic equipment identification (AEI) tag reader.

9. The system of claim 1, wherein the sensor comprises an imaging device for providing locomotive information comprising images observed from the locomotive whereby the images are displayed on the OCU remote from the locomotive being controlled by the OCU.

10. The system of claim 9 wherein the imaging device is a video camera.

11. The system of claim 9 wherein the imaging device is an ultrasonic device.

12. The system of claim 9 wherein the imaging device is a radar device.

13. The system of claim 9 further comprising a second imaging device, with one imaging device being located at the front of the locomotive and the other imaging device being located at the rear of the locomotive.

14. The system of claim 9 further comprising a transmitter on the OCU for transmitting a control signal controlling the operation of the imaging device.

15. The system of claim 9 further comprising an obstacle detection sensor for detecting obstacles within a predetermined distance of the locomotive.

16. The system of claim 1, further comprising a data base storing work orders detailing intended movement of locomotives in a railyard.

17. The system of claim 16, further comprising a data base transmitter for transmitting a work order to the OCU for a selected locomotive to be controlled by the OCU for movement in the railyard;

whereby the work order is displayed at the OCU for completion of the work order by the OCU operator in controlling the movement of the locomotive in the railyard.

18. The system of claim 16 further comprising a plurality of locomotives in the railyard each having a unique identifier, with the data base storing work orders associated with specific locomotives and an OCU transmitter for transmitting the identifier of the locomotive to be controlled.

19. The system of claim 16 further comprising a data input device on the OCU for the OCU operator to give notice of completion of work on the work order.

20. The system of claim 1, wherein the sensor comprises a locomotive health monitor for providing locomotive information comprising information indicative of the health of the locomotive.

21. The system of claim 20 further comprising a processor receiving the information indicative of the health of the locomotive and generating locomotive operational recommendations for display on the OCU.

22. The system of claim 20 further comprising a processor receiving the information indicative of the health of the locomotive and generating locomotive service recommendations for display on the OCU.

23. The system of claim 1, wherein the sensor comprises a locomotive condition monitor for providing locomotive information comprising information indicative of a condition of the locomotive.

24. The system of claim 23 further comprising a processor receiving the information indicative of the condition of the locomotive and generating a timed countdown indication responsive to the condition for display on the OCU.

25. A locomotive incorporating the remote control system of claim 1.
