上海城市轨道交通信号系统车地通信演进研究

Train-Wayside Communication Evolution of Shanghai Urban Rail Transit Signaling System

在介绍信号系统车地通信概念的基础上,阐述了上海城市轨道交通车地通信系统的现状,分析了既有车地通信系统中无线保真技术、长期演进技术面临的问题以及信号设备维护上的问题。提出建立长期演进的双制式车地通信系统的方案。针对上海城市轨道交通线网运营管理和新线建设的实际情况,从既有更新改造及新线建设两方面提出具体的双制式技术方案,以保证城市轨道交通信号系统运行的稳定、安全、高效。

After introducing the concept of signaling system train-wayside communication,the current situation of Shanghai rail transit train-wayside communication system is expounded,and the problems of Wi-Fi technology,long-term evolution technology and signaling equipment maintenance in the existing train-wayside communication system are analyzed.A scheme of establishing long-term evolution dual mode train-wayside communication system is put forward.According to the actual situation of Shanghai rail transit network operation management and new line construction,specific dual mode technical scheme is proposed from two aspects of existing line transformation and new line construction,so as to ensure the stable,safe and efficient operation of urban rail transit signaling system.
