机车运行途中故障诊断推理方法的研究

Study about Fault-tree-based Diagnosis and Reasoning System of Locomotive

针对机车运行途中故障诊断推理的方法进行了研究,通过利用系统专家的经验知识建立故障树模型,并运用双向推理控制策略和启发式搜索算法建立推理机,实现了机车运行途中故障诊断推理系统的动态建立。

This paper studied the method about fault diagnosis and reasoning of locomotive. The model of fault- tree was built by making use of the knowledge and experience of experts.And by making application of bi - directional reasoning and heuristic searching algorithm, the fault reasoning mechanism was constructed, and finally dynamic building of locomotive fault diagnosis and reasoning system was achieved.
