Abstract

A control system for a vehicle in a guideway network including a centralized control system configured to generate a first set of instructions. The control system further includes at least one de-centralized control system configured to generate a second set of instructions. The control system further includes an on-board controller configured to receive the first set of instructions and the second set of instructions during a same time period. The on-board controller is configured to receive the first set of instructions using a first communication technique. The on-board controller is configured to receive the second set of instructions via a second communication technique diverse from the first communication technique. If a discrepancy exists, the on-board controller is configured to execute a least restrictive of the first or second set of instructions. The control system is capable of seamlessly transferring control between the two control systems.

Claims

wherein the centralized control system is configured to transmit the first set of instructions to the on-board controller using a first communication technique and the at least one de-centralized control system is configured to transmit the second set of instructions to the on-board controller via a second communication technique different from the first communication technique,

wherein the on-board controller is configured to implement the least restrictive of the first set of instructions or the second set of instructions.

2. The control system according to claim 1, wherein the centralized control system is configured to transmit the first set of instructions to the on-board controller using an inductive loop communication system and the at least one de-centralized control system is configured to transmit the second set of instructions to the on-board controller via a radio communication system.

3. The control system according to claim 1, wherein the centralized control system is configured to generate the first set of instructions using a first algorithm, the at least one de-centralized control system is configured to generate the second set of instructions using a second algorithm, and the first algorithm is independent and diverse from the second algorithm.

4. The control system according to claim 1, further comprising an automatic supervision system configured to provide routing information to the centralized control system and the at least one de-centralized control system.

5. The control system according to claim 4, wherein the automatic supervision system is connected to the at least one de-centralized control system via a network, and the automatic supervision system is connected to the centralized control system via a wired connection.

6. The control system according to claim 1, wherein the at least one de-centralized control system comprises:

a first de-centralized control system having a first area of control; and

a second de-centralized control system having a second area of control,

wherein the first area of control and the second area of control overlap.

7. The control system according to claim 1, wherein the centralized control system is configured to generate the first set of instructions using a first algorithm, and the at least one de-centralized control system is configured to generate the second set of instructions using a second algorithm independent and diverse from the first algorithm.

8. The control system according to claim 1, wherein the on-board controller is configured to simultaneously receive the first set of instructions and the second set of instructions simultaneously.

9. The control system according to claim 1, wherein the on-board controller is configured to transmit a vehicle position and a vehicle speed to the centralized control system and to the at least one de-centralized control system.

10. The control system according to claim 1, wherein the on-board controller is configured to determine whether communication with one of the centralized control system or the at least one de-centralized control system is interrupted.

11. The control system according to claim 1, further comprising at least one set of field elements, wherein the at least one set of field elements is configured to collect data regarding the guideway and transmit the collected data to the at least one de-centralized control system, wherein each of the at least one set of field elements is associated with a respective at least one de-centralized control system.

12. A method of operating a vehicle in a guideway network, the method comprising:

receiving a first set of instructions from a centralized control system;

receiving a second set of instructions from at least one de-centralized control system, wherein the at least one de-centralized control system is stationary;

determining whether discrepancies exist between the first set of instruction and the second set of instructions, using an on-board controller;

implementing the first or second set of instructions if no discrepancy exists; and
