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ABSTRACTNeonThe neon ad screen is one of the means the company advertises its own image and product. Strong mobility, low energy consumption, economical utility, long life span, good effect, flexible manufacturing, and variety of colors.In this paper, the screen structure and operation principle of neon advertisement are described, and the general-purpose of the programmable controller is high, the program control is easy, and the application range is wide, the strong interference prevention ability, and the high reliability, etc. are controlled, and the control system of the screen of the advertisement of the neon advertisement is described The design of the temp based on the PLC control system is well suited for neon switch adjustments, resolving time and direction of scintillation, and how fast, reliable, and convenient operation. In the paper, we first proposed a design for the neon ad screen. Next, soft hardware design of neon ad screen control system was completed. The hardware portion includes the I / O layout and the PLC option, and the software portion contains flow charts and program trapezoidal diagrams. Fin...
