Expert System for Fault Diagnosis and Fault Diagnosis Method

摘要

The present invention relates to a fault diagnosis expert system and fault diagnosis method that can improve the reliability of fault diagnosis results by case-based the past factory diagnosis information. The expert system for fault diagnosis according to the present invention includes a first process of case-baseting the current fault diagnosis information, a second process of obtaining a possible element that can be predicted as a fault with the information of the current fault situation by using a matching algorithm, and a ranking. (Ranking) The third step of finding the most similar case of the past failure cases by comparing the current failure cases established by using the algorithm with the previous failure diagnosis information, and the step of determining whether to register the current failure cases in the previous failure cases. It consists of four steps.
