摘要
针对故障诊断专家系统实用性与通用性的矛盾,在简要分析专家系统工作原理的基础上,提出了一种以用户为中心的通用性故障诊断专家系统设计方案。研制通用性故障诊断专家系统开发平台,将规则推理、模糊决策、多传感器信息融合算法融为一体,形成阶梯式故障推理机制;对不同的诊断对象,只要设置好必要知识模块,就可自行生成专用故障诊断系统,并能自动输出诊断结果。
In order to overcome the contradiction between practicality and generality for fault diagnosis expert system, the design of user-centered general fault diagnosis expert system based on user is presented after the expert system is introduced concisely. Rule reasoning, fuzzy decision and information fusion algorithm are merged, and the hierarchical fault diagnosis method is accomplished. For different object, when necessary knowledge is given, a special fault diagnosis system will he automatically produced, and the diagnosis result will be given.
