基于 PLC 控制的流水灯设计【摘要】随着社会经济的发展,城市美化问题越来越引起人们的关注。由于流水灯所具有的特有流动感而广泛应用于广告控制及人们生活中,给人们一种美感,为人们生活带来乐趣。在现代生活中,大型楼宇的轮廓装饰或大型晚会的灯光布景,由于其变化多、功率大,数字电路则不能胜任。实现流水灯闪烁系统的控制方法很多,可以用标准逻辑器件、可编程序控制器 PLC、单片机等方案来实现。其中用标准逻辑器件来实现电路在很大程度上要受到逻辑器件如门电路等的影响,调试工作极为不易,而单片机编程复杂不容易掌握。因此,最终我们选择了用可编程的控制器 PLC 来实现系统功能的设计。可编程序控制器在工业自动化中的地位极为重要,广泛的应用于各个行业。随着科技的发展,可编程控制器的功能日益完善,加上小型化、价格低、可靠性高,在现代工业中的应用更加突出。城市交通灯控制采用的可编程制器具有可靠性高、维护方便,用法简单、通用性强等特点,本文用三菱 FX2N的可编程控制器控制流水灯闪烁来说明可编程控制器硬件、软件的设计。解决好流水灯控制问题将是保障城市美丽、时尚、快节奏生活的重要环节。三菱系列的可编程序控制器技术来实现对流水灯的信号控制。【关键词】PLC;流水灯;程序;控制Light Water Design Based on PLC Control【 Abstract 】 With the development of economy and society, city beautification problems caused by more and more people's attention. , due to water lamp has a unique sense of flow and widely applied in control and the life of people,give people a sense of beauty,to people the life brings fun.In modern life,a large building decorative outline or large Party light background,because of its changes, Big power,digital circuit is not equal to.Realization of road lights flashing system control method a lot of,can use the standard logic devices,programmable logic controller PLC, SCM scheme.The standard logic devices to realize the circuit to a large extent by the logic device such as a gate circuit and so on, debugging is extremely difficult,and the single chip microcomputer programm...
