【正文】 摘 要 隨著改革的不斷深入 ,社會主義市場經(jīng)濟的不斷繁榮和發(fā)展 ,大中小城市都在進行亮化工程。企業(yè)為展現(xiàn)自己的形象和產(chǎn)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 ,一種是采用霓虹燈管做成的各種形狀和多種彩色的燈管 ,另一種為日光等管或白熾燈管作為光源 ,另配大型廣告語或宣傳畫來達到宣傳的效果，大部分是采用霓虹燈。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(yīng)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(yè)自動化控制特別是順序控制中的方面具有比較突出的優(yōu)勢，在現(xiàn)實中人們也是多通過 PLC 去控制霓虹燈的。 關(guān)鍵詞 ： 西門子 S7200 霓虹燈 發(fā)展?jié)摿?Abstract Ceaselessness reforming subsequently is thorough, the socialist market economy ceaselessness prosperous and develops, big middlesized 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 , bee 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 , antiinterference 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 paratively outstanding advantage, in real gobetweens are also to go to control a neon much by PLC.
