焦西公司带钢厂精轧区工控机干扰分析

随着科学技术的发展,PLC在工业控制中的应用越来越广泛。PLC控制系统的可靠性直接影响到工业企业的安全生产和经济运行,系统的抗干扰能力是关系到整个系统可靠运行的关键。自动化系统中所使用的各种类型PLC,有的是集中安装在控制室,有的是安装在生产现场和各种电机设备上,它们大多处在强电电路和强电设备所形成的恶劣电磁环境中。焦西公司带钢厂精轧区的PLC的控制系统也不例外,处在恶劣的电磁环境中,受电磁干扰及雷击冲击的影响,造成网线连接困难,影响开车,耽误生产现象时有发生。为此进行系统分析,总结原因,做出相应改造从而避免类似现象的发生。

Coke West Company with Steel Mill IPC Interference Analysis

With the development of science and technology,PLC application in industrial control is more and more widely.PLC control system directly affects the reliability of the industrial enterprise safety production and economical operation,the anti-interference ability of the system is related to the whole system the key to reliable operation.Automation system used in the various types of PLC,some are centralized in a control room,some are installed in the production site and various electrical equipment,most of them in the electric circuit and electric device formed by the bad electromagnetic environment.Coke West company with steel rolling region of the PLC control system is no exception,in the bad electromagnetic environment,subject to electromagnetic interference and lightning impact,causing the network connection difficulties,influence of driving,delay production occurred from time to time.For this reason carries on the system analysis,summary,make corresponding reform so as to avoid the similar phenomenon.
