摘要
对船用核动力冷凝器的故障特征进行了分析,并据此建立了诊断专家系统.讲述了冷凝器的典型故障特征,并根据专家的经验及理论知识建立了知识库.针对故障的特点,专家系统采用了不确定性知识表示方法,推理机采用了双向推理机制.用VisualBasic6.0编制了专家系统程序.该系统对典型故障进行了诊断,得到了预期的效果.
By analyzing the fault features of the condenser of nuclear turbine, the diagnosis ES(Expert System)was established. According to the experience of the expert and theory knowledge, the knowledge Base was founded. To the fault features,the post production system was applied to the diagnosis ES,and the CF(Certainty Factor)was used to present the uncertainty of knowledge. Double_wards search was used in the Reasoning Machine.It chooses Visual Basic6.0 language to program the Diagnosis ES.The results of diagnosing the model faults by this system are satisfactory.
