Abstract

The present disclosure relates to a train autonomous control system (TACS) based method for train interval protection control, and an apparatus for the method. The method includes: step one: receiving, by a carborne controller (CC), a train operation command sent by an automatic train supervision (ATS) system to obtain a movement mission; step two: calculating, by the CC, a train guaranteed zone in real time according to information of train localization, car characteristics, and carborne controller characteristics; step three: calculating, by the CC, track resources required to be used in combination with current mission information according to the train guaranteed zone, and requesting to a wayside information control (WSIC) for information of collided trains occupying these track resources; and step four: sending, by the WSIC, a list of the collided trains on the track resources required to be used to the CC according to information of the track resources required to be occupied by a train on a whole line. Compared to the prior art, the present disclosure has the advantages of high operation efficiency, communication resource saving, reliability, safety, etc.

First claim

1 . A train autonomous control system (TACS) based method for train interval protection control, comprising the following steps:
step one: receiving, by a carborne controller (CC), a train operation command sent by an automatic train supervision (ATS) system to obtain a movement mission; step two: calculating, by the CC, a train guaranteed zone in real time according to information of train localization, car characteristics, and carborne controller characteristics; step three: calculating, by the CC, track resources required to be used in combination with current mission information according to the train guaranteed zone, and requesting to a wayside information control (WSIC) for information of collided trains occupying these track resources; step four: sending, by the WSIC, a list of the collided trains on the track resources required to be used to the CC according to information of the track resources required to be occupied by a train on a whole line. step five: when there is no valid train information in the list of the collided trains, recognizing, by the CC, that there is no collided train on the track resources required to be occupied; when there is valid train information in the list of the collided trains, initiating, by the CC, communication between the trains according to the train information in the list of the collided trains; and after the communication is established, negotiating, by the CC, with a CC of a related train for interval protection, and reporting a negotiation status to the WSIC; step six: after the WSIC receives a negotiation success status, authorizing the CCs to directly negotiate about occupation of the track resources between the trains; and step seven: when the track resources required to be used by the CC no longer intersect with the track resources required to be used by the corresponding collided train, ending, by the CC, the communication and negotiation with the CC of the corresponding collided train, and reporting the condition to the WSIC.

2 . The TACS based method for train interval protection control according to claim 1 , wherein the train guaranteed zone is a location that a train is currently guaranteed not to cross.

3 . The TACS based method for train interval protection control according to claim 1 , wherein when the train has a fault, faulty train interval protection is taken over by the WSTC, specifically as follows:
a location of the train is reported to the WSTC via a backup localization system (BLS) arranged on the faulty train; and the WSTC receives the train movement mission sent by the ATS system and replaces the CC to perform the train interval protection.

4 . The TACS based method for train interval protection control according to claim 3 , wherein the fault of the train is a fault of the CC.

5 . An apparatus for the TACS based method for train interval protection control according to claim 1 , comprising a WSIC, an object controller (OC), a wayside train control (WSTC), an ATS system, a CC, a BLS, and a balise, wherein the BLS is arranged on a train; the WSIC communicates with all train CCs; every two of the ATS system, the WSIC, and the WSTC are communicatively connected to each other; and the WSIC is connected to the OC.

6 . The apparatus according to claim 5 , wherein the ATS system is responsible for supervising and controlling train operation, and has the functions of train tracking operation, alarming and event reporting, operation adjustment, and operation control.

7 . The apparatus according to claim 5 , wherein the WSIC is responsible for line resource allocation and recovery, train sequence management, and signal and switch control; and the WSTC is responsible for handling temporary speed restriction, managing and tracking a faulty train, and replacing the faulty train to perform interval protection, resource application, and release.

8 . The apparatus according to claim 5 , wherein the OC is configured for implementing status collection and drive of wayside equipment;
the CC is configured to perform line resource request and release according to a plan, and to actively perform train control; the balise is configured to provide location information in combination with a line map; and the BLS is configured to provide a corresponding train identity (ID) and train location information to the wayside train control according to obtained balise information.

9 . An electronic device, comprising a memory, a processor, and a computer program stored on the memory and executable on the processor, wherein the processor is configured to perform, when executing the program, the steps of the TACS based method for train interval protection control according to claim 1 .

10 . A computer readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, causes the processor to perform the steps of the TACS based method for train interval protection control according claim 1 .
