Abstract

A portable computer system and method of operating a vehicle using the portable computer system in a communication-based train control (CBTC) system territory is provided. The portable computer system includes a sensor and a transceiver that is communicatively coupled to the sensor and to the CBTC system, wherein the portable computer system configured to be removably coupled to the vehicle. The method includes verifying that the vehicle is operating with one of a non-operational CBTC computer system and a non-CBTC computer system, and removably coupling a portable computer system including at least one sensor and a transceiver that is communicatively coupled to the sensor to the vehicle such that the transceiver is coupled in communication with the CBTC system.

Claims

1. A method of operating a vehicle in a communication-based train control (CBTC) system territory, said method comprising:

verifying that the vehicle is operating with one of a non-operational CBTC computer system and a non-CBTC computer system;

removably coupling a portable computer system to the vehicle, the portable computer system temporarily functioning as an on-board computer system to communicate with at least one wayside interface unit as the vehicle travels through the CBTC system territory;

communicatively coupling at least one sensor and a transceiver to the portable computer system,

wherein the portable computer system impermanently communicates with the at least one wayside interface unit and controls the vehicle based on information received from the at least one wayside interface unit.

2. A method in accordance with claim 1 wherein removably coupling a portable computer system further comprises removably coupling the portable computer system to an exterior portion of the vehicle.

3. A method in accordance with claim 1 wherein removably coupling a portable computer system further comprises magnetically coupling the portable computer system to the vehicle.

4. A method in accordance with claim 1 wherein removably coupling a portable computer system further comprises removably coupling a display screen to an interior portion of the vehicle, the display screen configured to display information that facilitates controlling the vehicle.

5. A method in accordance with claim 1 wherein removably coupling a portable computer system further comprises removably coupling an accelerometer to an exterior portion of the vehicle.

6. A method in accordance with claim 1 wherein removably coupling a portable computer system further comprises removably coupling a positioning system to an exterior portion of the vehicle.

7. A system for use with a vehicle operating in a communication-based train control (CBTC) system territory, said system comprising:

a portable computer system comprising;

a central processing unit; and

at least one global positioning link coupled to the central processing unit to receive positioning information of the vehicle in the CBTC system territory;

at least one sensor coupled to the portable computer system; and

a transceiver that is communicatively coupled to said at least one sensor and to said portable computer system, said portable computer system configured to be removably coupled to the vehicle such that when the portable computer system is coupled to the vehicle, said portable computer system is configured to temporarily function as an on-board computer system to communicate with a wayside interface unit when the vehicle enters and travels through the CBTC system territory, the portable computer system further configured to impermanently communicate with the wayside interface unit and control the vehicle based on information received from the wayside interface unit.

8. A system in accordance with claim 7, wherein said portable computer system is configured to be removably coupled to an exterior portion of said vehicle.

9. A system in accordance with claim 7 further comprising a magnet that is configured to removably couple said portable computer system to an exterior portion of said vehicle.

10. A system in accordance with claim 7 further comprising a display screen that is removably coupled to an interior portion of said vehicle, said display screen configured to display information that facilitates controlling the vehicle.

11. A system in accordance with claim 7 further comprising an accelerometer that is removably coupled to an exterior portion of said vehicle.

12. A system in accordance with claim 7 further comprising a positioning system that is removably coupled to an exterior portion of said vehicle.

13. A system in accordance with claim 7, wherein said at least one sensor is configured to determine at least one of whether a railcar has separated from said vehicle, an air pressure in a brake line, and whether equipment is dragging from said vehicle.

14. A system comprising:

a vehicle;

a portable computer system comprising;

a central processing unit; and

a plurality of global positioning links coupled to the central processing unit to receive positioning information of the vehicle in a communication-based train control (CBTC) system territory;

at least one sensor coupled to the portable computer system; and

a transceiver that is communicatively coupled to said at least one sensor and to the portable computer system, said portable computer system configured to be removably coupled to the vehicle such that when the portable computer system is coupled to the vehicle, said portable computer system is configured to temporarily function as an on-board computer system to communicate with a wayside interface unit when the vehicle enters and travels through the CBTC system territory, the portable computer system further configured to impermanently communicate with the wayside interface unit and control the vehicle based on information received from the wayside interface unit.

15. A system in accordance with claim 14, wherein said portable computer system is configured to be removably coupled to an exterior portion of said vehicle.

16. A system in accordance claim 14 further comprising a magnet that is configured to removably couple said portable computer system to an exterior portion of said vehicle.

17. A system in accordance with claim 14 further comprising a display screen that is removably coupled to an interior portion of said vehicle, said display screen configured to display information that facilitates controlling the vehicle.

18. A system in accordance with claim 14 further comprising an accelerometer that is removably coupled to an exterior portion of said vehicle.

19. A system in accordance with claim 14 further comprising a positioning system that is removably coupled to an exterior portion of said vehicle.

20. A system in accordance with claim 14, wherein said at least one sensor is configured to determine at least one of whether a railcar has separated from said vehicle, an air pressure in a brake line, or whether equipment is dragging from said vehicle.
