Automatic Turn-back Scheme for CBTC System Based on Train to Train Communication

Abstract

CBTC (communication based train control) system with train to train communication is one of the main research directions for the next generation train control system. Automatic turn-back is an important function of the urban transit signaling system. In order to realize the automatic turn-back function of unmanned operation CBTC system based on train to train communication, this paper described the system architecture of a CBTC system with train to train communication. Combined with the control principle of the system, it designed an unmanned automatic turn-back scheme. The control logic of the scheme is clear, and fully considers the security and operational efficiency of the implementation. By controlling the switch resource separately and reducing the communication link, the solution takes less time than the turn-back operation of traditional CBTC system.
