基于车-车通信技术的既有信号系统改造研究

Research on reconstruction of existing signal system based on train-to-train communication technology

从国内既有信号系统的现状出发,分析传统基于通信的列车运行控制(CBTC)系统在既有信号系统改造时存在的问题,提出一种基于车-车通信的信号系统改造方案;阐述系统的架构、原理及特点,并对该系统在既有信号系统改造时的可行性与改造方案进行研究与分析。该系统简化传统 CBTC 信号系统架构,减少系统接口,降低传输延时,提高控制精度,精简地面设备,降低改造难度,缩短改造工期,可广泛应用于城市轨道交通的既有信号系统改造。

Based on the present situation of signal system of existing rail transit in China,this paper analyzes the problems existing in reconstruction of existing rail transit with traditional CBTC system,and puts forward signal system based on train-to-train communication in reconstruction of existing rail transit.The structure,principle and characteristics of the system are described,and the feasibility and reconstruction scheme of the system in existing rail transit are studied and analyzed.The system simplifies the traditional CBTC signal system architecture,reduces the system interface,reduces the transmission delay,improves the control accuracy,simplifies the ground equipment,reduces the difficulty of reconstruction,shortens the reconstruction period,and will be more widely used in the reconstruction of the existing rail transit.
