Development of Vehicle Diagnosis and Maintenance Information System
Abstract
Electrical fuel injection engine is widely used in modern automobile. It greatly increases integration capability of engine, at the same time, the technology of fault diagnosis of engine demands more and more high technology. So, to develop vehicle diagnosis and maintenance information system for fault diagnosis of engine looks especially necessary.
Arming at the problems existing in maintenance of electrical injection engine, combining with the characteristics of expert system, the architecture of expert system for fault diagnosis of electrical injection engine and the key technology for its realization are studied in this paper.
This article elaborated the automobile examination technology historical development, Domestic and foreign research situation as well as expert system present's trend of development. Has profited from the engine diagnosis system which developes. By using Visual Basic and Access etc under Windows XP and applying the diagnosis method of artificial intelligence and the object-oriented programming technology, to develop the fault diagnosis expert system of engine, which has a friendly interface, four functional parts of the fault diagnosis, the knowledge base management, the database management and online training are realized. Using ADO technology, the way of data base management is studied; the performance and the diagnosis function of vehicle diagnosis and maintenance information system of fault diagnosis are improved.
Key words：Expert System Fault Diagnosis Maintenance Information
