综采设备故障诊断的框架知识表示

Fault Diagnosis Knowledge Representation of Multi-purpose Coal Mining Equipment Based on Frame Structure

专家系统主要产品包括三个组成部分 :知识库、推理机和用户接口 ,其核心是知识库 .有效合理的知识表示是专家系统中知识处理的基本前提 .采煤机、液压支架和乳化液泵站是组成综采设备的三种主要设备 .作者以这三种设备为基础 ,对综采设备故障诊断专家系统中的知识表示问题 ,提出了用框架结构对其知识进行表示 .讨论了框架结构知识表示的推理和搜索技术 ,并可以用C++语言实现 。

The expert system is composed of knowledge store, reasoning machine and user connecting. Knowledge is the core of the expert system. Whether it is represented correctly and validly or not is a very important precondition for knowledge processing in expert system. Coal mining machine, hydraulic pressure support and emultion pump station consist of the main parts of multi purpose coal mining equipment. Basing on the main parts and aiming at knowledge representation problem of expert system, the authors present frame structure to reasoning and searching technique for frame structure knowledge representation. Correct result can be accomplished in Visual C++.
