摘要
多功能车辆总线(Multifunctional Vehicle Bus,MVB)在保障列车运行控制和状态监测方面起着至关重要的作用,而列车的运行环境以及网络负载环境十分复杂,因此,为保障列车的运行安全,需对MVB总线进行数据监测与分析。文中分析了MVB的通信协议,提出了基于嵌入式的MVB数据实时监测和时序分析程序,测试了相关功能的实现情况,验证了设计方案的正确性,从而对列车运行时的故障预测和健康管理提供帮助。
MVB plays an important role in ensuring train operation control and condition monitoring,while the train operation environment and network load environment are very complex.Therefore,in order to ensure the operation safety of the train,the MVB bus is monitored and analyzed.This paper analyzes the communication protocol of MVB,puts forward the real-time monitoring and timing analysis program of MVB data based on embedded system,tests the realization of relevant functions,verifies the correctness of the design scheme,then provides help for fault prediction and health management during train operation.
