Abstract

Systems and methods for remotely controlling a rail vehicle are provided. In one embodiment, a remote operator control system includes a communication link to send and receive rail vehicle information, an operator interface, and a controller. The controller is configured to send, through the communication link, a request to establish communication with a positive train control system on-board a selected rail vehicle based on an operating condition. In response to receiving confirmation of communication with the positive train control system, the control is configured to receive positive train control information for the selected rail vehicle through the communication link, and display the positive train control information for the selected rail vehicle on the operator interface.

Claims

1. A remote operator control system comprising:

a communication link to send and receive rail vehicle information;

an operator interface including a first transfer control input configured to receive operator input for transferring control of operation of a selected rail vehicle from manual control by the remote operator control system to automatic control by an energy management system; and

a controller configured to send, through the communication link, a request to establish communication with a positive train control system on-board the selected rail vehicle based on an operating condition, send, through the communication link, a request to establish communication with the energy management system on-board the selected rail vehicle based on the operating condition, in response to receiving confirmation of communication with the positive train control system, receive positive train control information for the selected rail vehicle through the communication link, display the positive train control information for the selected rail vehicle on the operator interface, and send, through the communication link, control commands to the energy management system to take control of operation of the selected rail vehicle from the remote operator control system in response to receiving operator input through the first transfer control input.

2. The system of claim 1, wherein the operating condition includes the communication link being in a wireless communication range of the positive train control system.

3. The system of claim 1, wherein the remote operator control system is temporarily coupled to a cradle and the operating condition includes removal of the remote operator control system from the cradle.

4. The system of claim 1, wherein the positive train control information includes location information for the selected rail vehicle and travel restriction information that is based on the location information.

5. The system of claim 1, wherein the controller is configured to, in response to receiving confirmation of communication with the energy management system, receive rail vehicle state information for the selected rail vehicle through the communication link, and display the rail vehicle state information for the selected rail vehicle on the operator interface.

6. The system of claim 5, wherein the operator interface includes manual control inputs configured to receive operator input for manually adjusting operation of the selected rail vehicle;

and

the controller being configured to send, through the communication link, control commands to manually adjust operation of the rail vehicle in response to receiving operator input through the manual control inputs.

7. The system of claim 6, wherein the operator interface includes a second transfer control input configured to receive operator input for transferring control of operation of the selected rail vehicle from automatic control by the energy management system to manual control by the remote operator control system;

and

the controller being configured to send, through the communication link, control commands to the energy management system to relinquish control of operation of the selected rail vehicle to the remote operator control system in response to receiving operator input through the second transfer control input.

8. The system of claim 6, wherein the controller is configured to receive, through the communication link, control commands from the energy management system to take control of operation of the selected rail vehicle from the remote operator control system in response to a travel condition.

9. The system of claim 8, wherein the travel condition includes the selected rail vehicle crossing from a rail yard to a main line.

10. A method for remotely controlling a rail vehicle comprising:

transferring control of operation of a rail vehicle to a remote operator control system for manual control of the rail vehicle by a rail vehicle operator in response to a first operating condition including when the rail vehicle enters a predefined track zone; and

transferring control of operation of the rail vehicle to an energy management system on-board the rail vehicle for automatic control of the rail vehicle by the energy management system in response to a second operating condition including when the rail vehicle exits the predefined track zone.

11. The method of claim 10, further comprising:

receiving rail vehicle state information from the energy management system at the remote operator control system; and

displaying the rail vehicle state information on an operator interface of the remote operator control system.

12. The method of claim 10, further comprising:

receiving positive train control information from a positive train control system on-board the rail vehicle at the remote operator control system; and

displaying the positive train control information on an operator interface of the remote operator control system.

13. The method of claim 10, wherein the first operating condition includes operator input commanding manual control of the rail vehicle by the remote operator control system, and the second operating condition includes operator input commanding automatic control of the rail vehicle by the energy management system.

14. The method of claim 10, wherein the predefined track zone is a rail yard.

15. A remote operator control system comprising:

a communication link to send and receive rail vehicle information;

an operator interface; and

a controller configured to send, through the communication link, a request to establish communication with a positive train control system and an energy management system on-board a selected rail vehicle, in response to receiving confirmation of communication with the positive train control system, receive travel information for the selected rail vehicle through the communication link, in response to receiving confirmation of communication with the energy management system, receive rail vehicle state information for the selected rail vehicle through the communication link, and display the travel information and the rail vehicle state information for the selected rail vehicle on the operator interface, wherein the controller is configured to transfer control of operation of the selected rail vehicle from the remote operator control system to the energy management system.

16. The system of claim 15, wherein the controller is configured to transfer control of operation of the selected rail vehicle from the energy management system to the remote operator control system.

17. The system of claim 16, wherein the controller is configured to relinquish control of operation of the selected rail vehicle to the energy management system.
