Abstract

An urban rail transportation fusion signaling system and method. The fusion signaling system includes: an autonomous train supervision system, configured to send a train operation plan; a first wayside management system, operating under a Train Autonomous Circumambulate System (TACS) system and configured to generate line resource allocation information according to the train operation plan; a second wayside management system, operating under a Communications-Based Train Control (CBTC) system and configured to generate operation permission information according to the train operation plan; and a car controller, provided on a rail transportation train and configured to: perform traffic control according to the line resource allocation information when the train is traveling under the TACS system; or perform traffic control according the operation permission information when the train is traveling under the CBTC system.

Claims (45)

1 . An urban rail transportation fusion signaling system, comprising:

an autonomous train supervision system, configured to send a train operation plan;

a first wayside management system, operating under a Train Autonomous Circumambulate System (TACS) system and configured to generate line resource allocation information according to the train operation plan;

a second wayside management system, operating under a Communications-Based Train Control (CBTC) system and configured to generate operation permission information according to the train operation plan; and

a car controller, provided on a rail transportation train and configured to: perform traffic control according to the line resource allocation information when the train is traveling under the TACS system; or perform traffic control according to the operation permission information when the train is traveling under the CBTC system;

wherein the second wayside management system comprises:

a computer interlocking configured to perform control and status information collection on a wayside equipment;

a zone controller configured to obtain a protection zone of the train according to location information of the train and the train operation plan, so as to generate the operation permission information of the train; and

a line controller configured to temporarily limit a speed of the train.

2 . The urban rail transportation fusion signaling system according to claim 1 , wherein:

the autonomous train supervision system and the car controller operate normally under both the TACS system and the CBTC system.

3 . The urban rail transportation fusion signaling system according to claim 2 , wherein the first wayside management system comprises:

an object controller, configured to perform control and status information collection on the wayside equipment; and

a wayside resource manager, configured to perform allocation and recovery of a line resource according to the status information of the wayside equipment and the train operation plan.

4 . The urban rail transportation fusion signaling system according to claim 3 , wherein:

when the train is operating under the TACS system, the car controller is configured to: send a line resource allocation request to the wayside resource manager according to the location information of the train and the train operation plan, so as to obtain the line resource allocation information, and

calculate a movement authorization of the train according to the line resource allocation information and location information of an adjacent vehicle, so as to perform traffic control on the train.

5 . The urban rail transportation fusion signaling system according to claim 1 , wherein:

when the train is operating under the CBTC system, the car controller is configured to: send the location information of the train to the zone controller, so as to obtain the operation permission information, and

calculate a movement authorization of the train according to the operation permission information and the status information of the wayside equipment, so as to perform traffic control on the train.

6 . The urban rail transportation fusion signaling system according to claim 1 , further comprising: a centralized maintenance system, wherein the centralized maintenance system is configured to perform status supervising and maintenance on the autonomous train supervision system, the first wayside management system, the second wayside management system and the car controller, and the centralized maintenance system operates normally under both the TACS system and the CBTC system.

7 . The urban rail transportation fusion signaling system according to claim 6 , wherein:

the first wayside management system further comprises: a wayside train manager, and the wayside train manager is configured to temporarily limit the speed of the train.

8 . The urban rail transportation fusion signaling system according to claim 7 , wherein:

when the train operates under the TACS system, the autonomous train supervision system, the car controller, the centralized maintenance system, and an object controller, a wayside resource manager and the wayside train manager of the first wayside management system are interconnected through a data communication system; and

when the train operates under the CBTC system, the autonomous train supervision system, the car controller, the centralized maintenance system, the computer interlocking, the zone controller, and the line controller of the second wayside management system are interconnected through the data communication system.

9 . A method for using an urban rail transportation fusion signaling system, comprising:

providing the urban rail transportation fusion signaling system according to claim 1 ;

dividing a track where the train operates into a Communications-Based Train Control (CBTC) system zone and a Train Autonomous Circumambulate System (TACS) system zone;

deploying the urban rail transportation fusion signaling system in the CBTC system zone or the TACS system zone;

providing a transition zone between the CBTC system zone and the TACS system zone;

arranging at least three transponders at intervals in the transition zone; the at least three transponders comprise a first transponder, a second transponder, and a third transponder; and

switching from the CBTC system to the TACS system or switching from the TACS system to the CBTC system by the car controller according to information of the transponders, so as to enable cross-zone operation of the train between the CBTC system zone and the TACS system zone.

10 . The method for using an urban rail transportation fusion signaling system according to claim 9 , wherein when the urban rail transportation fusion signaling system is deployed in the TACS system zone, the switching from the CBTC system to the TACS system or switching from the TACS system to the CBTC system by the car controller according to information of the transponders comprises the steps of:

allowing the train to operate under the CBTC system from the CBTC system zone to the transition zone;

respectively connecting the car controller with a first wayside management system and an adjacent vehicle in the TACS system zone through a data communication system according to information of the first transponder, so as to obtain line resource allocation information and location information of the adjacent vehicle;

calculating, by the car controller, a movement authorization of the train according to the line resource allocation information and the location information of the adjacent vehicle, so as to perform traffic control on the train;

switching the car controller from the CBTC system to the TACS system according to information of the second transponder; and

disconnecting the car controller with an equipment in the CBTC system zone and controlling the train to exit the transition zone and to operate to the TACS system zone according to information of the third transponder.

11 . The method for using an urban rail transportation fusion signaling system according to claim 9 , wherein when the urban rail transportation fusion signaling system is deployed in the CBTC system zone, the switching from the CBTC system to the TACS system or switching from the TACS system to the CBTC system by the car controller according to information of the transponders comprises the steps of:

allowing the train to operate under the TACS system from the TACS system zone to the transition zone;

connecting the car controller with a second wayside management system in the CBTC system zone through a data communication system according to information of the third transponder, so as to obtain operation permission information and status information of a wayside equipment;
