摘　　要： 为实现对罐身电阻焊机的远程故障诊断,研制了一种基于公用电话网与PLC的专家系统。分析了系统的软硬件结构,介绍了产生式规则与故障树框架结构相结合的知识表示方法以及单故障源型诊断推理逻辑,并简述了该系统的通信实现方法。运行实践表明,该系统知识模型适应性好,推理结果基本符合实际情况,有助于罐身电阻焊机的远程快速故障诊断。 In order to implement fault diagnosis of can - body resistance welding machine in long - distance, an expert system based on PSTN and PLC was developed. Its structures of software and hardware were analyzed, and its frame type for knowledge presentation of the fault tree and single fault source diagnostic reasoning were interpreted. Some application examples in practice showed that this system is adaptive and effective to can- body resistance welding machine, thus useful for fault diagnosis of can - body resistance welding machine in long - distance and real - time.
