讨论了一个称为ＲＴＦＤＥＳ的故障诊断专家系统的结构和实现过程，ＲＦＤＥＳ是由知识库管理子系统ＫＢＭＳ和故障诊断子系统ＤＳ组成．它采用产生式和二元树两种知识表示方法并提供了全自动诊断方式、半自动诊断方式、手动诊断方式、报警监控四种诊断方式以及知识编译功能．ＫＢＭＳ负责对知识库的维护、求精和编译ＤＳ能根据从工控机采集的地址状态和对话信息得出故障．本系统适合顺序控制类生产线的故障诊断。
The structure and implementation process of a fault diagnosis expert system called RTFDES are discussed. RFDES is composed of KBMS and fault diagnosis subsystem DS. It uses production and binary tree two knowledge representation and provides automatic diagnostic methods, semi-automatic diagnostic methods, manual diagnostic methods, alarm monitoring four diagnostic methods and knowledge compilation. KBMS is responsible for the maintenance of the knowledge base, refinement and compilation DS can be based on IPC from the address of the state machine and dialogue information derived failure. The system is suitable for sequence control of production line fault diagnosis.
