摘要
设计了基于PLC的智能化电力设备故障诊断系统 ,结构上可分为信息模块、输入模块、处理模块、控制模块和输出模块。控制模块是故障诊断系统的核心 ,它根据控制指令 ,利用专家知识 ,完成从特征到故障原因的识别工作。PLC的开关量输入模块作为开关量故障信号的输入装置 ,模拟量输入模块可用作模拟量故障信号的输入装置。这两种模块都能方便地实现对设备的在线监测。
An intelligent diagnosis system based on PLC(Programmable Logic Controller) for elecrtic power equipment is brought forward.It is made up of information module,input module,processing module,control module and output module.The control module is the core of the system,it identifies the fault characters and their causes according to the control statements received and the expert knowledge.The binary input module is used for the input of digital fault signals while the analog input module for analog fault signals.With these two modules the on-line monitoring of electric power equipment is easily carried out.
