摘要:
基于列车通信网络的常见故障问题，总结了列车通信网络现场检测方法。在现场检测中，对帧错误、过程数据、帧间隔、信号幅值、信号上升沿时间及干扰等项目的测试实用性较高。梳理了列车通信网络现场故障处理案例的主要处理过程及测试结果，总结了列车通信网络故障发生模式，归纳了排查列车通信网络故障的一般步骤。
Abstracts:
Based on the common failures of train communication network, train communication network on-site detection method is summarized. For on-site detection, the test practicality on items such as frame-to-frame error, process data, frame interval, signal amplitude, signal rising edge time and distur-bance is higher. The main treatment process and test results of train communication network on-site failure disposal cases are sorted. The train communication network failure modes and the general steps of troubleshooting train communication network failures are summarized.
