摘 要

在现实生活中，大多数人们更加希望使用PLC去控制霓虹灯。随着社会的不断发展，霓虹灯拥有效率高、使用寿命长、功耗低等特点。霓虹灯的工作温度很低，使用过程中受环境影响小，并且霓虹灯的制作设计简易，能够呈现多种颜色，霓虹灯的控制过程及方法比较简易，霓虹灯设计能够有很强烈的动感呈现，宣传效果突出，经济实用。

因此，霓虹灯控制系统工程的发展拥有非常巨大的发展空间。在日新月异的今天，霓虹灯行业也如火如荼的发展着，霓虹灯更加趋近发展更加环保绿色，其质量也更加持久耐用，并且能够展现出的颜色也更加多样。霓虹灯市场的激烈竞争，其控制系统也变得更加重要。

本次课程设计配以图文，针对霓虹灯控制系统进行了着重介绍其基于PLC系统平台，并对PLC硬件展开说明，PLC由于使用便捷，可靠性强，抗干扰强，编程容易等特点使得其应用广泛。霓虹灯能够给予广告更好的宣传，当其能够基于PLC的时候，能够实现其自动控制，生活中的交通灯也是可以基于这一原理，应用广泛。

Abstract: In our daily life, people frequently make use of PLC to control the neon lights.With the rapid development of society, neon lights has many advantages ,which can work efficiently and have long life with less energy. The working temperature of PLC can be very low, and it is hard to make PLC be bothered by the surrounding. The neon lights can be produced easily, and also show many different colors. There are many ways to control the actions of neon lights .The neon lights can show many dynamic pictures causing the great advertising consequence with low consumptions.

Therefore, the development of the neon lights controlling projects has foreseeing future. with the industry of neon lights becoming more mature, the neon lights tend to the green side ,and keep long life and show more colors. When it comes to aggregate competition and the trend of marketing changes, the technology of neon lights plays more important role .

This project is about to talk about the system of PLC’s controlling neon lights, and the keys to introduce the combination of its parts .PLC can work in different surroundings, and it can be very convenient to use, which can be programmed, so it can be used widely. The neon light can provide better advertising effects. If the neon lights can be based on PLC technology ,the traffic lights are an application of this theory.

Key words: plc,neon lights,controlling system
