基于故障树的机车故障诊断系统设计

DESIGN OF TRAIN FAULT DIAGNOSIS SYSTEM BASED ON FAULT TREE

给出基于故障树的机车故障诊断系统设计方案。采用公式形式将故障树的结构信息保存在文本文件中,在运用故障树进行推理诊断时,提出基于Java语言SWING包中JTree控件解析保存故障树的结构与节点信息的方法,从而方便快速完成故障推理。给出基于模块化故障树及割集计算方法,为大型故障树诊断与定性分析提供了较好的解决方案。

This paper presents the design scheme of train fault diagnosis system based on fault tree.The structure information of the fault tree was saved in the text file by using equation.When using fault tree for reasoning diagnosis,we proposed a method to analyze and save the structure and node information of fault tree based on JTree of the SWING package in Java,so as to facilitate the rapid completion of fault reasoning.Based on the modular fault tree and cut set calculation method,this paper also provides a better solution for large-scale fault tree diagnosis and qualitative analysis.
