Abstract

A train management method includes sending a registration request to a takeover zone controller (ZC) in response to determining that the train enters an area of co-management, so that the takeover ZC calculates a second movement authority (MA) of the train according to the registration request and exchanges information with a handover ZC, determining a target MA according to a first MA of the handover ZC for the train and the second MA of the takeover ZC for the train, and traveling according to the target MA within the area of co-management. The area of co-management is composed of a part of an area of management of the handover ZC and a part of an area of management of the takeover ZC.

First claim

What is claimed is:

1. A train management method for a train, the method comprising:
sending a registration request to a takeover zone controller (ZC) in response to determining that the train enters an area of co-management, so that the takeover ZC calculates a second movement authority (MA) of the train according to the registration request, and exchanges information with a handover ZC, wherein the area of co-management is composed of a part of an area of management of the handover ZC and a part of an area of management of the takeover ZC, and the area of co-management is obtained according to a maximum speed of the train within the area of management and a calculated time for the takeover ZC to receive the registration request and calculate the second MA;
determining a target MA according to a first MA of the handover ZC for the train and the second MA of the takeover ZC for the train; and
traveling according to the target MA within the area of co-management.

2. The method according to claim 1 , wherein the MA is used for indicating a route range of an obstacle ahead from a current position of the train, and the determining a target MA according to a first MA of the handover ZC for the train and the second MA of the takeover ZC for the train comprises:
determining a distance between a destination of a route range indicated by a first MA received at each moment and the current position of the train and a distance between a destination of a route range indicated by a second MA of the takeover ZC for the train received at each moment and the current position of the train; and

selecting, as the target MA, an MA that indicates a route range having a destination closer to the current position of the train.

3. The method according to claim 1 , wherein the determining that the train enters an area of co-management comprises:
determining that a minimum safe rear end of the train enters the area of co-management.

4. The method according to claim 1 , further comprising:
performing, by the train, braking in a case that communication of the train with the ZC is interrupted during traveling within the area of co-management.

5. The method according to claim 1 , further comprising:
sending a handover request to the handover ZC in response to determining that a maximum safe front end of the train leaves the area of co-management, so that the handover ZC stops calculating the first MA.

6. The method according to claim 1 , further comprising: sending a deregistration request to the handover ZC in response to determining that the minimum safe rear end of the train leaves the area of co-management.

7. A train management system, comprising a zone controller (ZC) and a train communicatively connected with the ZC, wherein
the ZC comprises a handover ZC and a takeover ZC;
the handover ZC is configured to calculate a first movement authority (MA) of the train;
and the takeover ZC is configured to calculate a second MA of the train in response to receiving a registration request sent by the train, and exchange information with the handover ZC,
wherein the train sends the registration request to the takeover ZC in response to determining that the train enters an area of co-management, so that the takeover ZC calculates the second MA of the train according to the registration request; the area of co-management is composed of a part of an area of management of the handover ZC and a part of an area of management of the takeover ZC; and the area of co-management is obtained according to a maximum speed of the train within the area of management and a calculated time for the takeover ZC to receive the registration request and calculate the second MA.

8. The system according to claim 7 , wherein the train comprises an onboard controller configured to:
receive the first MA and the second MA;
determine a distance between a destination of a route range indicated by a first MA received at each moment and the current position of the train and a distance between a destination of a route range indicated by a second MA received at each moment and the current position of the train;
select, as a target MA, an MA that indicates a route range having a destination closer to the current position of the train;
control, according to the target MA, the train to travel within the area of co-management.

9. A computer-readable storage medium storing a computer program, wherein when the program is executed by a processor, the processor implementing a train management method, applied to a train, the method comprising:
sending a registration request to a takeover zone controller (ZC) in response to determining that the train enters an area of co-management, so that the takeover ZC calculates a second movement authority (MA) of the train according to the registration request, and exchanges information with a handover ZC, wherein the area of co-management is composed of a part of an area of management of the handover ZC and a part of an area of management of the takeover ZC, and the area of co-management is obtained according to a maximum speed of the train within the area of management and a calculated time for the takeover ZC to receive the registration request and calculate the second MA;
determining a target MA according to a first MA of the handover ZC for the train and the second MA of the takeover ZC for the train; and
traveling according to the target MA within the area of co-management.

10. An electronic device, comprising:
a memory, storing a computer program; and
a processor, configured to execute the computer program in the memory to implement a train management method, applied to a train, the method comprising:
sending a registration request to a takeover zone controller (ZC) in response to determining that the train enters an area of co-management, so that the takeover ZC calculates a second movement authority (MA) of the train according to the registration request, and exchanges information with a handover ZC, wherein the area of co-management is composed of a part of an area of management of the handover ZC and a part of an area of management of the takeover ZC, and the area of co-management is obtained according to a maximum speed of the train within the area of management and a calculated time for the takeover ZC to receive the registration request and calculate the second MA;
determining a target MA according to a first MA of the handover ZC for the train and the second MA of the takeover ZC for the train; and
traveling according to the target MA within the area of co-management.
