Knowledge Representing in Turbogenerator Fault Diagnosis System

本文主要研究机组振动故障诊断系统的知识表示方法,提出了适用于诊断系统的振动分类表;对振动诊断知识采用“框架+规则”表示法,可以提高系统的推理效率;并对不确定知识的表示作了初步的研究.

This paper focusses on the knowledge representing methods in turbogenerator vibration fault diagnosis systems, and presents a classification table of turbogenerator vibration, that is suitable to the diagnosis system. 'Frame+Rule' method is adopted for representing the diagnosis knowledge in order to raise the reasoning efficiency of the diagnosis system. The method of representing uncertain knowledges is also discussed.
