摘要
介绍了CRH3型动车组列车通信网络的基本结构和组成,详细分析了列车网络总线传输介质的电气性能指标。推导了列车网络总线的分布参数模型。针对TCN总线测试中近端串扰参数经常不合格的问题,利用所推导的分布参数模型对TCN总线的近端串扰参数进行了深入研究,并对CRH3型动车组列车网络总线的布局布线方法提出了优化建议。
The present paper introduced architecture and characteristic of the train communication network （TCN） of CRH3. The electric characteristic of TCN was analyzed in detail. The distribution parameter model of TCN was deduced; Because of the problem of the near end crosstalk （NEXT） parameter was often unqualified, the simulation model of TCN based on the distribution parameter model was researched. Suggestions of optimization on the network cabling were given.
