高频网络化UPS故障诊断专家系统设计

Design of Fault Diagnosis Expert System for High Frequency Network UPS

针对高频网络化UPS的特点 ,提出了故障诊断的策略和设计步骤 ,从故障诊断专家系统的硬件体系结构和软件设计两方面叙述了本诊断系统的构造 ,采用将故障树和基于产生式规则专家系统相结合的非模型化方法 ,构造了专家系统知识库 。

On the bosis of the character of high frequency network UPS,this paper introduces strategy and design steps of fault diagnosis,specifies the construction of the expert system through hardware architecture and software designing,constructs a knowledge base for the expert system by non model method combining with fault tree and expert system based on production rule together,and gives some examples and experiments.
