摘要
基于通信的列车控制(CBTC)系统已在城市轨道交通中得到广泛使用,并在工程实践中展现出较大的优势,但其具体实现方案仍是现阶段研究的一个重要方面。提出了一种基于车-车通信的新型CBTC系统,给出了系统构架和功能原理,并就相邻列车通信和全网列车通信两种实现方案进行了讨论。分析了该新型CBTC系统的核心——车载控制器的具体功能,对基于车-车通信的CBTC系统在实际应用中面临的问题及其解决方案进行了探讨。
Due to the greater advantages in engineering projects, communication based train control(CBTC) system has been widely used in urban rail transit system, but the application of the system still remains a difficult issue in current research. In this paper, a CBTC system based on train-to-train communication is proposed, the system structure and principle are presented, two implementation schemes—the neighboring train communication and whole network train communication—are discussed. Then, the performance of the on-board controller is analyzed, which is the core of the new CBTC system, problems facing the application of CBTC based on train-to-train communication and the solutions are discussed.
