继电控制电路的交互式故障诊断研究

The Study of Interactive Diagnosis on Relay Control Circuits

文章针对继电控制电路故障诊断的现状,提出交互式故障诊断的思想。首先介绍了交互式诊断平台的搭建方法,然后重点讨论了交互式诊断专家系统中知识表示和推理的方法。文章采用改进的故障树方法用于故障知识表示,并建立了相应的搜索和推理策略,通过实例分析证明这种方法具有较好的推理效率。

According to the actuality of the diagnosis of relay control circuits,the paper presents an interactive diagnosis method.After a brief introduction of the interactive diagnosis platform construction,the knowledge expression and reasoning mechanism in the interactive diagnosis expert system is given more attention and discussed in detail.It uses improved fault tree method to describe the diagnosis knowledge and establishes searching and reasoning strategies accordingly.An example is also given to prove the feasibility and effectiveness of this method.
