摘要:
分析了长沙磁浮列车在调试过程中出现的一起MVB 网络通信故障,指出MVB 信号尾帧异常振荡是导致故障的直接原因。根据传输线理论,结合对振荡现象的分析,排查出列车MVB 网络外接设备存在接触不良是导致故障的根本原因。通过理论公式与仿真建模研究了可能导致故障发生的主要因素,全面地解释了故障现象,为提高列车网络通信系统电磁兼容性和可靠性提供了重要参考。
Abstract:
A MVB network communication fault that occurred during the test run of Changsha maglev train was discussed , abnormal oscillation of the last MVB signal frame was found to be the direct reason. According to the theory of transmission lines, and combining with the analysis of oscillation phenomenon, this paper points out that the poor contact in the equipment of MVB network was the root cause. Through the theoretical formula and simulation modeling, the major factors that might cause a similar fault were researched, and the fault phenomenon was explained comprehensively. It also provides important reference value for the improvement of the EMC and reliability of train network communication system.
