随着科学技术的飞速发展,PLC控制系统已经被广泛的应用,随着PLC控制系统的日益普及,提高PLC控制系统的抗干扰能力就变得十分重要了,虽然PLC本身就具备较好的抗干扰能力,但由于PLC控制系统大多都处于强电电路等恶劣的环境中,因此很多的因素都会对PLC的控制系统造成不同程度的干扰,只有通过加强单片机PLC控制系统的抗干扰能力才能够保证PLC控制系统的安全稳定的运行。本文针对单片机PLC控制系统的主要干扰因素进行概述分析,并就如何提高单片机PLC控制系统的抗干扰能力提出一些可行的方法。
With the rapid development of science and technology, PLC control system has been widely used. With the increasing popularization of PLC control system, it becomes very important to improve the anti-interference ability of PLC control system. Although PLC itself has better anti-interference Interference ability, but most of the PLC control systems are in a harsh environment such as strong electrical circuits, so many factors will cause varying degrees of interference to the PLC control system, only by strengthening the anti-interference ability of the PLC control system of the microcontroller can be guaranteed PLC control system safe and stable operation. In this paper, an overview of the main interference factors SCM PLC control system, and how to improve the SCM PLC control system anti-jamming ability to put forward some feasible methods.
