摘要
从电磁干扰的类别及耦合通道出发,结合PLC控制系统的内外结构,分析了PLC控制系统应用中存在的主要电磁干扰源,以及电磁干扰源对PLC控制系统和整个自动控制系统的影响;并结合工程实际,探讨了如何采取具体有效的干扰抑制技术来保证PLC控制系统的正常工作。
Based on a brief introduction of the categories of electromagnetic interference, this paper analyzed the potential electromagnetic interference sources in the light of the exterior and interior structures of PLC system, and expounded their negative influence on PLC system as well as the whole controlling system. This paper also explored several specific measures to suppress interference effectively in specific engineering practice, which would guarantee smooth operation of PLC system.
