| 摘 要： | 列车通信网络(TCN)是现代列车控制、状态检测、故障诊断以及旅客服务等信息传输的高性能局域网;在介绍列车通信网结构的基础上,对多功能车辆总线和绞线式列车总线的线路冗余技术分别进行了研究,仔细分析了MVB冗余控制模块的输入输出信号,对其进行了子模块化设计,并通过给出线路受扰信号的时序图,详细讨论了WTB的线路切换;最后得出列车通信网的线路冗余技术保证了TCN系统的高可靠性。

| Abstract: | Train Communication Network is a high capability network intended to transmit the information of vehicle control,status checking,fault diagnosis and passenger service.Configuration of TCN is introduced.Study is made on the line redundancy of,respectively,MVB and WTB.The input and output signals of MVB redundancy control module is analyzed.Four functional sub blocks of the control module is designed.And the switchover of WTB is expatiated according to Line_Disturbance signal.At last results show that line re... |
