| 摘 要： | 在故障树分析的基础上,建立电动公交车的故障诊断专家系统,用户通过人机界面提供故障征兆,专家系统利用知识库中存储的知识(包括规则和故障知识),按一定的推理策略逐步求解问题,推理结果再通过人机界面显示给用户.另外,系统还添加解释机制,对规则、故障树以及推理的过程和各中间结果进行必要的解释.用户rl-'~断知识库进行完善、更新也通过人机界面进行.

| Abstract: | Based on the fault tree analysis,Electric Bus Fault Diagnosis Expert System Fault can provide the failure mode for users,and according to a certain reasoning strategy,solve the problems through the stored knowledge base(including knowledge of the rules and failures). Then,the results will be showed to users through man-machine interface. In addition,the system also has explaining mechanisms for those rules,fault trees,reasoning processes and intermediate results. And the diagnosis knowledge base can be upda... |
