摘要
城市轨道交通信号系统目前基本上均采用基于无线通信的列车控制系统(CBTC),车辆段设置的供列车调头使用的灯泡线给信号系统的网络通信带来难题。针对此问题,提出网络切换方案,并对地面4天线的部署方式进行探讨,对存在的问题进行分析,为实现灯泡线信号车地通信的连续性和有效性提供技术依据。
At present, Communication Based Train Control(CBTC) system is mainly applied in urban rail transit, the bulb line which used for train turning around in depot brings problems to signaling network communications. This article focuses on the problems, puts forward the network switching scheme, and discusses the setting mode of four antennas through analysis of the problems, for providing technical basis for the train-ground communication continuity and effectiveness of the bulb line.
