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。关键词　PLC；霓虹灯；单片机；三菱仿真器FXGPWIN 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 controlling rapid , reliable , simple , become the priority that 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, in real go-betweens are also to go to control a neon much by PLC.
