摘　　要：简要介绍CR200J-3型动力集中动车组编组形式和列车网络控制系统拓扑结构的基础上,分析了CR200J-3型动力集中动车组在特定区段WTB通信异常问题及其形成原因,并提出了优化方案。实际应用表明,优化后该型动车WTB通信抗干扰性明显提高,降低了故障率,为保障列车的可靠运行提供重要支撑。Based on introduction of consist type and TCMS topology of CR200J-3 power concentration EMUs, the problems on the train’s WTB communication at a specific area were discussed, and the corresponding solutions were proposed in this paper. The testing results in practice operation demonstrated that the capability on anti-interference had been obviously improved, while the fault rate was decreased, which would provide an important support for train’s reliable running.
