摘要
隨著改革的不斷深入,社會主義市場經濟的不斷繁榮和發展,大中小城市都在進行亮化工程。企業為展現自己的形象和產品,一般都會采用通過霓虹燈廣告屏來這種廣告手法，所以當我們夜晚走在大街上,馬路兩旁各色各樣的霓虹燈廣告隨處可見。這就涉及到如何去控制霓虹燈的亮滅、閃爍時間及流動方向等諸多控制問題，如何去快捷、可靠、簡單的去控制，成為人們考慮的重點，在這我認為PLC最適合去解決這些問題，因為PLC具有通用性強、使用方便、適應面廣、可靠性高、抗干擾能力強、編程簡單等特點。并且PLC在工業自動化控制特別是順序控制中的方面具有比較突出的優勢，在現實中人們也是多通過PLC去控制霓虹燈的。

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 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.
