具有“黑板—框架”型知识库的故障诊断专家系统

Fault Diagnosis Expert System with Knowledge Bases of Blackboard—Frame Structure

本文介绍了在IBM—PC/XT和0520—CH系列微机用Turbo—Prolog实现的通用机器故障诊断专家系统FDES—BF(Fault Diagnosis Expert System—Blackboard Frame)。它采用了“黑板—框架”结构的知识表示方法,正反向综合推理策略,模块式的系统结构,利用与之相应的生成工具可以很方便地建立各种机器的故障诊断专家系统。

The paper introduces a machine fault diagnosis expert system. The system was written in Turbo--prolog running in IBM--PC/XT and 0520--CH microcomputer.This system adopts 'Blackboard--Frame' structure (knowledge expression method), forwarding and backwarding mixed inference tactics and modular system structure.Using its shell (development tool), we can build sorts of machine fault diagnosis expert systems very conveniently.
