摘 要霓虹灯广告屏是企业宣传自身形象和产品的手段之一，因其具有强运动性、低能耗、经济实用、寿命长、效果好、制作灵活、色彩多样等特点，广泛应用在生产生活中。本文在阐述霓虹灯广告屏结构和工作原理的基础上，利用可编程控制器通用性强、编程控制容易且广泛、广泛的适用范围、较强的抗干扰能力、高可靠性等特点,设计了霓虹灯广告屏控制系统，基于 PLC 的控制系统较好地解决了霓虹灯开关的调节、闪烁时间和方向，以及如何快速、可靠、操作方便等问题。在论文中首先提出了有关霓虹灯广告屏的设计方案；其次我完成了霓虹灯广告屏控制系统的软硬件设计。硬件部分包括 I/O 分配表和 PLC 选型，软件部分包括绘制流程图和程序梯形图；最后通过系统对所设计的控制系统进行测试，满足了设计要求。关键词：霓虹灯广告屏；PLC；控制系统ABSTRACTNeon advertising screen is one of the means for enterprises to publicize their own image and products. Because of its characteristics of strong sports, low energy consumption, economic and practical, long life, good effect, flexible production and various colors, it has been widely used in production and life.On the basis of expounding the structure and working principle of neon advertising screen, this paper makes use of the features of PLC, such as strong universality, easy to program and control, wide application range, strong anti-interference ability and high reliability, The control system of neon advertising screen is designed. The control system based on PLC solves the problems of neon switch adjustment, flashing time and direction, and how to operate quickly, reliably and conveniently. In this paper, the design scheme of neon advertising screen is proposed firstly;Then the hardware and software design of the neon advertising screen control system is completed. The hardware part includes I / O distribution table and PLC selection, and the software part includes drawing flow chart and program ladder diagram....
