摘要
为了保障列车安全运行,将故障树分析法(FTA)应用于列车数据展示中心(DS)的预警模块。通过在DS中创建设备系统故障树,对建立的故障树模型进行定性和定量分析,得出该系统的等效模型和故障发生概率。DS将故障概率与事先设置的预警阈值比较,从而发出相应的预警警报。实例应用表明,故障树分析法是系统故障诊断的一种有效方法,对于保障列车运行安全具有重要的应用价值。
In order to ensure the safety of the running train,fault tree analysis is applied into the early warning （EW）module of the train data showing center.A fault tree of equipment system is established,then the quantitative and qualitative analy-sis of the fault tree model is carried out,and the equivalent model of the system and fault probability is obtained.The DS system will make the corresponding alert by comparing the failure probability with the prior warning threshold.The applica-tion result shows that FTA is an effective way to diagnose system fault for the security of the running train.
