Research on Backup System of Train Operation Control System Based on Vehicle to Vehicle Communication

Abstract

Objective At present, represented by TACS(train autonomous control system)and based on vehicle to vehicle communication, the backup system of train operation control system is not perfect, and needs to be further discussed and studied. Method By analyzing new operational requirements and combined with the development of new technologies, a TACS backup system based on environment identification is discussed. The architecture and function of TACS and its backup system are introduced in detail, and technical difficulties in building the TACS backup system are analyzed. The application of the above system in train operation space monitoring and degraded operation scenarios is expounded. Result & Conclusion In case of train failure and degraded operation, the TACS backup system can improve operation efficiency and enhance operation safety.
