基于数据库技术的故障诊断知识库管理系统设计

Knowledge Base Management System Designed for Fault Diagnosis Expert System Based on Database Technology

为解决传统大型复杂系统故障诊断专家系统中存在的知识库庞大、难于维护管理的问题,结合数据库技术设计了一套基于Windows平台的知识表示和知识库管理系统。该系统充分利用了数据库技术,实现了对知识库中知识的存储、添加、删除、修改和查询以及编辑过程中的一致性、完备性和冗余性要求,通过将该系统应用到运载火箭测试发射中的故障诊断专家系统中,一定程度上实现了知识处理的自动化,为运载火箭故障诊断专家系统的开发和运用奠定了重要基础。

To resolve the problem that the knowledge base of complex system is too large to manage, a knowledge base management system （KBMS） is constructed. The system makes fully use of database technology to realize knowledge store, adding, deletion, modification and seeking. Besides, it can also check the consistency and integrality of knowledge. When applied in the launch vehicle fault diagnosis expert system this system establishes an important base for the whole launch vehicle fault diagnosis expert system.
