本文针对液压系统故障诊断问题,根据系统和故障的分级特性,建立了相应于“深浅知识库”的双层故障诊断模型,给出了针对这种模型的知识处理方法,讨论了推理中为解决不确定性而使用的模糊综合评判方法。
In this paper, aiming at the problem of fault diagnosis of hydraulic system, according to the classification features of system and fault, a two-layer fault diagnosis model corresponding to “Shallow Knowledge Base” is established, and the knowledge processing method for this model is given. Uncertainty and the use of fuzzy comprehensive evaluation method.
