摘要
基于通信的列车控制(CBTC)系统采用独立于轨道的车—地双向通信设备实现列车与地面控制系统之间的连续式双向通信.介绍了CBTC系统下无线车地通信原理及通信异常情况,并针对其关键设备无线接入点(AP)进行一定程度的剖析.利用上海地铁11号线的设备,通过现场抽样调查、故障汇总和比较分析等方法,对引起AP设备故障的各个末端原因进行分析,确定了AP设备故障的3种要因及解决方案,提出了建立采用TD-LTE技术的通信架构的设想.
Communication based train control(CBTC) system uses independent equipment of the rail train to realize continuous two-way communication between the train and ground control system. The principle of wireless train to wayside communication(TWC) and abnormal communication in the CBTC system was introduced,and key equipment access point (AP) was analyzed. Taking example of Shanghai metro line 11, sampling survey, fault summary and comparison analysis methods were used to analyze the end causes of AP failure, and 3 kinds of failure solutions for AP equipment were provided. Then, a communication architecture based on TD-LTE technology was put forward.
