中文摘要：
旅客列车是一个复杂的大动态系统，轮对是旅客列车机械故障的多发部位，为及时有效地防范和预警列车轮对故障，在分析我国旅客列车基本结构、安全装备情况的基础上，以列车轮对状态在线监测为基础，设计了基于TCN的网络化旅客列车轮对状态在线监测系统，并给出其具体实现方案．系统由列车在线状态监测与故障诊断主机、车辆级状态监测分机和各车栽设备监测模块组成．每节车辆由车辆级状态监测分机通过MVB将车辆内部各状态监测模块联结成为监测网络，利用WTB将全列车的车辆级状态监测分机连为一体，构成一个完整的、基于TCN标准架构的列车状态监测与故障诊断系统，为开展列车上其他机械部分、电气部分等的故障诊断构建了一个TCN标准的网络平台．图6，参15．
英文摘要：
After analyzing the basic structures and security equipments of the passenger train, an online fault diagnosis system based on the TCN was designed to be alert to the potential fault. The system was made up of the host, the vehicle level state monitoring extension and the vehicle equipment state monitoring module. The modules were connected into a monitoring network by the extension through the MVB, and the extensions were joined to a comprehensive system based on the TCN through WTB for the fault diagnosis of the other mechanical and electrical components.6figs., 15refs.
