基于RST及FTA的综合传动装置故障诊断专家系统的应用研究

摘要

文章对综合传动装置的故障机理进行了深入分析，采用粗糙集数据挖掘算法和故障树分析法进行知识获取，解决知识获取难的问题。同时推理机制采用改进RETE匹配算法，提高了匹配效率。并利用Access2003数据库构建知识库，利用VC++开发专家系统软件。最后通过综合传动装置专家系统软件对专家系统的诊断结果进行验证。结果表明：此专家系统能够对故障做出正确判断，并且诊断快速，效率高，进而充分证明了此专家系统设计的有效性。%Failure mechanisms for comprehensive transmission device was analyzed deeply on this article, deciding to adopt the rough set data mining algorithms and fault tree analysis to obtain the knowledge, to solve the difficult problem of knowledge acquisition. At the same time,the reasoning mechanism based on improved RETE matching algorithm improves the matching efficiency and the use of Access2003 database to build knowledge base. Making use of the VC+ + to develop the fault diagnosis expert system software. Fi-nally, the result of the diagnosis was verified by expert system software for comprehensive transmission de-vice. The results show that:This expert system can make the right judgments on the fault,and rapid diagno-sis,high efficiency,and thus fully proved the effectiveness of this expert system design.
