摘要
针对市域铁路运营需求进行分析;从基于WLAN无线通信的CBTC移动闭塞信号系统、基于LTE无线通信的CBTC信号系统、基于信标通信的点式ATC信号系统、基于部分区域实现无线通信的点-连式信号系统、基于音频数字轨道电路的准移动闭塞ATC信号系统和基于LTE无线通信的点-连式信号系统等方面对市域铁路的信号系统制式进行分析;阐述基于LTE无线通信的点-连式信号系统的构成、基本控制原理和功能优势,其能很好地满足市域铁路的运营需求,具备市域铁路信号系统规划和建设的可行性。
The operation requirement of Suburban Railway is analyzed. The type and mode of signaling system for Suburban Railway is comprehensively analyzed, including the WLAN-based CBTC movable block signaling system, LTE-based CBTC signaling system, beacon-based point ATC signaling system, point-continuous signaling system, quasi-movable block ATC signaling system based on video and digital track circuit and LTE- based point-continuous signaling system. The composition, basic control principle and functions of LTE- based point-continuous signaling system are introduced, demonstrating that it can well meet the requirement of Suburban Railway and have future potential for wide deployment.
