浅析地铁门控系统的故障树诊断方法研究

Study on Fault Tree Diagnosis Method of Metro Gating System

论文把列车门系统作为研究对象,以门控系统的内部结构、工作原理、运行情况、故障模式为重点进行理论研究,并对列车车门系统进行定性和定量分析,将问题具体化,建立故障树。再针对故障树中底事件的重要度,对门控系统的系统可靠性进行评估。为地铁列车车门系统故障诊断提供理论积累,具有一定的工程应用价值。

The train door system is taken as the study object in this paper. It focuses on the theoretical research into the internal structure, working principle, operation and fault mode of the gating system. The qualitative and quantitative analysis is made on the train door system. The problems are embodied, and the fault tree is set up. According to the importance degree of the base event in the fault tree, the system reliability of the gating system is evaluated. It provides theoretical accumulation for fault diagnosis of the train door system, and has certain engineering application value.
