AI Technical Summary

Technical Problem

In fully automated train control systems, if a sudden accident occurs between two stations, preventing subsequent trains from passing, existing technologies cannot effectively manage reverse trains crossing the boundary of the area controller, affecting emergency evacuation efficiency and system safety.

Method used

By synchronizing and sharing obstacle status between adjacent zone controllers (ZCs), the authorization of reverse train movement across zone controller boundaries is realized, including path configuration, obstacle detection, and handover of authorization information, ensuring the safe reverse movement of trains.

Benefits of technology

It improves evacuation efficiency in emergency evacuation scenarios, ensures that operators have more convenient options, and guarantees the safety and reliability of the system in emergency situations.

Abstract

The application relates to a method for moving authorization of a reverse train across the boundary of a region controller and a storage medium, which comprises the following steps: step S1, when the authorization of a reverse region is limited, two adjacent region controllers (ZCs) synchronize the state of the authorization of the reverse region; step S2, the adjacent ZCs synchronize the state of the barrier train in the authorization of the reverse region; and step S3, an upstream ZC hands over the train in the authorization of the reverse mode to a downstream ZC. Compared with the prior art, the application has the advantages that the reverse train in an emergency evacuation scene is protected, and the safety of a full-automatic train operation control system is further ensured.
