Abstract

The present disclosure provides a train turn-back control method, device and system. The method includes: determining first state information of a train when confirming that a turn-back instruction is received; directly resetting the first state information to obtain second state information; and performing turn-back control on the train according to the second state information. The present disclosure can realize turn-back control on the train based on a single set of vehicle on-board-device, thereby improving the turn-back success rate and turn-back efficiency of the train, and reducing the hardware consumption.

First claim

What is claimed is:

1. A train turn-back control method based on a single set of vehicle on-board-device, comprising:
determining a pre-turn-back movement authority (MA) when a train runs to a first station parking spot, wherein the pre-turn-back MA is a line from an initial tail position of the train to a destination of a turn-back rail;
pulling a train to the turn-back rail according to the pre-turn-back MA;
when the train stops at the turn-back rail, in response to confirming that a turn-back instruction being received, determining current first state information of the train, wherein the current first state information includes at least one of a first train head position, a first train tail position, and a first train running direction;
resetting the first state information to obtain second state information, wherein the second state information includes a second train head position, a second train tail position, and a second train running direction;
determining a turn-back MA of the train based on the second train head position and the second train tail position, wherein the turn-back MA is a line from the second tail position to a second station parking spot; and
pulling the train to the second station parking spot according to the turn-back MA and the second train running direction to complete turn-back control on the train.

2. The train turn-back control method according to claim 1 , wherein:
resetting the first state information to obtain the second state information comprises:
interchanging the first train head position with the first train tail position, and performing a reverse operation on the running direction to obtain the second train head position, the second train tail position and the second running direction.

3. The train turn-back control method according to claim 2 , wherein determining the turn-back MA of the train based on the second train head position and the second train tail position comprises:
sending, when the train is positioned in a control zone of a zone controller, the second train head position and the second train tail position to the zone controller; wherein the zone controller is configured to determine the turn-back MA of the train based on the second train head position and the second train tail position.

4. The train turn-back control method according to claim 2 , wherein determining the turn-back MA of the train based on the second train head position and the second train tail position comprises:
determining the turn-back MA of the train based on the second train head position and the second train tail position by a vehicle on board controller.

5. A train turn-back control device based on a single set of vehicle on-board-device, comprising:
a processor; and
a memory for storing instructions, when executed, causing the processor to control a train to turn back, wherein:
the processor comprises:
a determining module configured to:
determine a pre-turn-back movement authority (MA) when the train runs to a first station parking spot, wherein the pre-turn-back MA is a line from an initial tail position of the train to a destination of a turn-back rail;
control pulling the train to the turn-back rail according to the pre-turn-back MA;
when the train stops at the turn-back rail, in response to confirming that a turn-back instruction being received, determine current first state information of the train, wherein the current first state information includes at least one of a first train head position, a first train tail position, and a first train running direction; and
determine a turn-back MA of the train based on a second train head position and a second train position, wherein the turn-back MA is a line from the second tail position to a second station parking spot;

a resetting module configured to reset the first state information to obtain second state information, wherein the second state information includes the second train head position, the second train tail position, and a second train running direction; and
a turn-back control module configured to pull the train to the second station parking spot according to the turn-back MA and the second train running direction.

6. The train turn-back control device according to claim 5 , wherein:
the resetting module is specifically configured to:
interchange the first train head position with the first train tail position, and perform a reverse operation on the running direction to obtain the second train head position, the second train tail position and the second running direction; and

the turn-back control module is specifically configured to:
pull the train to the second station parking spot according to the turn-back MA and the second train running direction.

7. The train turn-back control device according to claim 6 , wherein the turn-back control module comprises:
a determining sub-module configured to determine the turn-back MA of the train based on the second train head position and the second train tail position; and
a pulling sub-module configured to pull the train to the second station parking spot according to the turn-back MA and the second running direction to complete turn-back control on the train.

8. The train turn-back control device according to claim 7 , wherein the device also comprises a zone controller; when the train is positioned in a control zone of the zone controller, the determining sub-module is specifically configured to:
send the second train head position and the second train tail position to the zone controller when the train is positioned in a control zone of the zone controller; and
the zone controller is configured to determine the turn-back MA of the train based on the second train head position and the second train tail position.

9. The train turn-back control device according to claim 7 , wherein the determining sub-module is also specifically configured to:
determine the turn-back MA of the train by a vehicle on board controller based on the second train head position and the second train tail position.

10. A train turn-back control system based on a single set of vehicle on-board-device, comprising:
a zone controller; and
a train turn-back control device, including:
a processor; and
a memory for storing instructions, when executed, causing the processor to control a train to turn back, wherein:
the processor includes:
a determining module configured to:
determine a pre-turn-back movement authority (MA) when the train runs to a first station parking spot, wherein the pre-turn-back MA is a line from an initial tail position of the train to a destination of a turn-back rail;
control the pulling train to the turn-back rail according to the pre-turn-back MA;
when the train stops at the turn-back rail, in response to confirming that a turn-back instruction being received, determine current first state information of the train, wherein the current first state information includes at least one of a first train head position, a first train tail position, and a first train running direction; and
determine a turn-back MA of the train based on a second train head position and a second train position, wherein the turn-back MA is a line from the second tail position to a second station parking spot;

a resetting module configured to reset the first state information to obtain second state information, wherein the second state information includes the second train head position, the second train tail position, and a second train running direction; and
