摘要
文章对LTE技术在城市轨道交通信号系统车-地通信的系统架构进行设计和分析,并提出了LTE在信号系统中的传输介质、车载天线、时钟同步、试车线和正线LTE网络部署、无线覆盖的设计方案,为LTE技术在信号系统中的设计和应用提供参考。
Design and analyse the system architecture of vehicle-ground communication based on LTE technology in signalling system of urban rail transit,and the design schemes for transmission medium,on-board antenna,clock synchronization,LTE network deployment in the test line and main line,and wireless coverage in the signalling system based on LTE are proposed.It provides reference for the design and application of LTE technology in the signalling system.
