摘要
对专家系统和基于规则的专家系统进行了研究,尤其对基于规则的专家系统中的模式匹配算法进行了深入分析和理解。在此理论基础上,将一种高效的模式匹配算法——Rete算法引入到实际的故障的诊断系统中,以保证故障诊断的高效性和准确性。为此在实际系统中,借助规则引擎将故障信息规则化,并将故障诊断流程以层次分明的XML文档进行表示,来模拟领域专家进行故障诊断和故障排除的功能。实践表明,该故障诊断系统可以提高定位故障的速度和准确度。
This paper makes a research on expert system and rule-based expert system. In particular,it makes a thorough analysis and understanding on the pattern matching algorithm. Based on this theory,an efficient pattern matching algorithm-rete algo- rithm is introduced into the actual fault diagnosis system in order to guarantee the efficiency and accuracy of fault diagnosis.By means of rule engine, in this system fault information is represented by rules,and fault diagnosis flow is represented by XML docu- ment to simulate the function of experts＂ fault diagnosis and troubleshooting. The practice shows that this system can improve the speed and accuracy of fault locating.
