基于C/S+B/S双模式的分布式远程诊断专家系统

分布式远程诊断专家系统（DRFDES）是故障诊断领域的发展趋势之一。为此文章深入研究了其工作原理、实现的硬软件结构及工作过程，分析了Web数据库的体系的两层C／S结构和三层B／S结构厦其在DRFDES中的优缺点，在该基础上提出了一种基于C／S和B／S混合模式的数据库体系的分布式远程故障诊断专家系统，探讨了故障诊断知识库的更新模式，并对分布式远程诊断专家系统实现的理论基础和关键技术进行了研究。

Distributed Remote Fault Diagnosis Expert System Based on C/S+B/S Mixed Mode

Distributed remote fault diagnosis expert system(DRFDES) is one trend of fault diagnosis fields.The working principles,hardware frames,software frames and work processes are researched in depth.Web database system structures such as two-level C/S structure and three-level B/S structure is analyzed emphatically,and their advantages and disadvantages in DRFDES are introduced.In order to overcome these disadvantages,the distributed remote fault diagnosis expert system database structure based on C/S and B/S mixed mode is presented in this paper.Updating mode of diagnostic knowledge base is discussed,and the theory foundation and key technologies of this distributed remote fault diagnosis expert system are researched at last.
