摘 要

随着改革的不断深入,社会主义市场经济的不断繁荣和发展,大中小城市都在进 行亮化工程。企业为展现自己的形象和产品,一般都会采用通过霓虹灯广告屏来 这种广告手法?所以当我们夜晚走在大街上,马路两旁各色各样的霓虹灯广告随 处可见。这就涉及到如何去控制霓虹灯的亮灭、闪烁时间及流动方向等诸多控制 问题?如何去快捷、可靠、简单的去控制?成为人们考虑的重点?在这我认为 PLC最适合去解决这些问题?因为 PLC具有通用性强、使用方便、适应面广、可 靠性高、抗干扰能力强、编程简单等特点。并且 PLC在工业自动化控制特别是顺 序控制中的方面具有比较突出的优势?在现实中人们也是多通过 PLC去控制霓虹 灯的。

Abstract

Ceaselessness reforming subsequently is thorough , the socialist market economy

ceaselessness prosperous and develops, big middle-sized and small cities spend a

project all in the light being in progress. Enterprise is to display self image and the

product , the general city is adopt to do this advertisement by neon sign screen

therefore gimmick, thinking that we walk in night on the main street, the

miscellaneous neon sign of both sides of the street can be seen everywhere. This deals

with a lot of control problems such as go out , evasive bright time and the direction

being on the move how to go to control a neon right away , how to go and go and

Keywords? siemens S7-200; Neon;developing controlling rapid , reliable , simple , become the priority that potential people considers, I think

that PLC is be fit to go and resolve these problems , strong , use face to go to the

lavatory , adapt to because of PLC has General Availability most broad , the high ,

anti-interference ability of reliability is strong , the programming waits for a

characteristic simplely in this. And PLC controls aspect in controlling especially in

proper order in the industrial automation having comparatively outstanding advantage,

2

in real go-betweens are also to go to control a neon much by PLC.
