Research On Knowledgebase Management System In Vehicle Fault Diagnosis

Knowledgebase Management System (KBMS) is a very important part of vehicle fault diagnosis expert system, knowledge required by the expert system during it running is all provided by knowledgebase, reasoning and decision-Making of the expert system are all the result of applying the knowledge of KBMS to match , conclude and calculate. So, the quality of knowledgebase directly influences the whole vehicle fault diagnosis expert system, and that constructing high-efficient and consummated KBMS plays a very important role in improving the performance of the expert system . This paper briefly introduces basic theory of knowledgebase and knowledgebase management system, and analyses the characteristic of vehicle fault diagnosis, then puts forward the method of knowledge classify and express. According to the characteristic of knowledge of vehicle fault diagnosis, the paper use SQL Server to establish vehicle fault diagnosis knowledgebase, on this foundation it designs a knowledgebase management system, the system makes fully use of database technology to realize knowledge store, add, delete, modify and seek. Besides, it can also check the consistency and integrality of knowledge .In a word the KBMS establishes an important base of the whole vehicle fault diagnose expert system.
