基于数据库的汽车故障诊断专家系统研究

为了解决传统专家系统知识修改和扩充困难,提出基于数据库的汽车故障诊断系统的设计方案,重点研究了实现这一方案的三个关键技术:利用规则表示法表示知识;逆向推理的工作流程;故障诊断的人机界面。研究结果表明,将数据库与专家系统相结合是切实可行的,可以简化编程设计、提高诊断效率。

On Expert System of Automobile Fault Diagnosis Based on Database

In order to overcome the difficulty in modification and expansion of knowledge in traditional expert system,this paper proposes a project of automobile fault diagnosis system based on database and focuses on the three key techniques to implement the project,which involve the respects of expressing the production knowledge by rules,workflow of backward inference and interactive interface of fault diagnosis.The result indicates that the method of combining database with expert system is feasible and can simplify programming design and improve diagnosis efficiency as well.
