Research On Expert System Of Fault Diagnosis Of Car Based On Network

Maintenance and repair are very important in the use of car. Withthe better qua1ity of 1if e, more and more cars wi11 enter comonfami1ies. 1t is a very important prob1em to decrease the occurrenceof car fault and increase the efficiency of fau1t diagnosis. Expertsystem of diagnosis of car based on network is a new so1ution to thisprob1em. This paper discussed the so1ution in detail. First, commonfau1t s in car, re1ative reasons and genera1 methods and princip1eswere searched. Second, a primary knowledge base of fault diagnosisof car was bui1t. Frame representation and object--orientedrepresentation app1ied to the know1edge base. And the expert systemis based on e1ementary know1edge --reasoning. Fina11y, this paper gavethe imp1ementation of the expert system.' The software structurereferenced the C1ient/Server mode1 in popu1ar network techniques. Thec1 ient software was a Web browser, Microsoft Internet Exp1orer(IE). Theserver software was Microsoft 1nternet Information Server (1IS). Inthe mode1, expert system software deve1oped second1y on the side ofthe server software: Active Server Pages (ASP ) cooperated withComponent 0bject Mode1 (C0M) in imp1ementing the expert system.
