摘要

轨道列车上的电磁干扰会对列车网络控制系统的通信产生随机性干扰，进而造成网络通信的丢包问题。通过搭建列车网络控制系统电磁干扰模拟试验台，研究EMC 干扰对列车通信网络（TCN）的影响，重点研究静电放电干扰和脉冲群干扰对通信特性的影响，根据试验数据得到TCN 丢包率随干扰大小的变化趋势，并进一步对所测数据进行分析建模，得到了基于EMC 干扰的TCN 丢包预测模型。

Abstract

EMI on the train will cause random interference to the communication of the train network control system, and then cause the packet loss of the network communication. The influence of EMC interference on the train communication network (TCN) was studied by building a simulation experiment platform of train network control system, focusing on the influence of electrostatic discharge immunity test and electrical fast burst immunity test on communication characteristics. Based on the experimental data, the variation trend of the TCN packet loss rate with the interference size was obtained, and the data was analyzed and modeled, then the TCN packet loss prediction model based on EMC interference was obtained.
