基于PLC的远程设备故障诊断方法研究

摘要

with the continuous upgrading and development of computer technology, equipment manufacturing enterprises for PLC remote equipment fault diagnosis method is also getting higher and higher. In recent years, PLC development is very rapid, is also widely used in various products, is a collection of remote monitoring, control, diagnosis and other communication technology as one of the general industrial control device. The development of computer network technology makes the remote equipment fault diagnosis based on PLC possible, changes the traditional equipment monitoring, fault diagnosis method, through the network to transmit all kinds of data to the remote expert system, through the network monitoring equipment running status, fault occurrence. This article will briefly introduce the remote equipment fault diagnosis method based on PLC, which can provide reference for the remote fault diagnosis technology of large equipment.%随着计算机技术的不断升级和发展，设备制造企业对于PLC的远程设备故障诊断方法要求也越来越高。近年来，PLC发展极为迅速，也被广泛运用到各类产品中，是集远程监测、控制、诊断等通信技术为一体的通用工业控制装置。计算机网络技术的发展使基于PLC的远程设备故障诊断成为可能，并改变了传统设备监控、故障诊断方法，通过网络将各类数据传递给远程专家系统，实现了通过网络监控设备的运行状态、故障发生情况。本文将简单介绍基于PLC的远程设备故障诊断方法，长期为大型设备的远程故障诊断技术提供参考。
