摘要
传统诊断方法各有优缺点,对于大型装备的故障诊断来说,由于故障的复杂性、故障信息的多样性,单一的诊断方法满足不了实际应用的要求。为此,在介绍基于案例、模型、神经网络专家系统诊断推理方法的基础上,论述了基于案例、模型和神经网络的混合推理策略,给出了建立混合推理系统的方法,并在某型雷达的故障诊断系统中得到了应用。
All kinds of Traditional Diagnosis Methods have their own advantages and disadvantages.For the largescale equipment,because of the complexity of its fault models and the variety of its fault information,it is very difficult for every diagnosis method to satisfy the real application by itself.Based on the introduction of casebased,modelbased and NNbased (Neural Networkbased)reasoning approach to the fault diagnosis,this paper discusses the hybrid reasoning strategy on case,model and neural network,and gives the method to establish the hybrid reasoning system.In the end,it is used in a radar fault diagnosis system.
