摘　　要：介绍了出口以色列特拉维夫轻轨列车的背景和运营方式,从在工程应用中遇到的实际问题出发,分别从网络拓扑、设备内部处理时间、传输机制等多方面进行对比分析,总结分析出连挂列车TCMS信号传输延时过高的原因,在保证原有硬件平台不升级的基础上,通过软件优化解决了工程问题,满足了车辆运营的实际需要。This paper describes the background and operation mode of the light rail train exported to Tel Aviv,Israel.Starting from the practical problems encountered in the engineering application,it compares and analyzes the network topology,internal processing time of equipment,transmission mechanism and other aspects,and summarizes the reasons for the long TCMS signal transmission delay of the train.On the basis of ensuring that the original hardware platform is not upgraded,the engineering problems are solved through software optimization,which meets the actual requirements of operation.

关 键 词：连挂列车 TCMS 信号传输延时 软件优化
