Tacs based method for train interval protection control, and apparatus for method

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.
