摘 要
 本論文主要介紹一種由可編程序控制器（PLC）、紅外傳感器、電動機(jī)為主要器件構(gòu)成的新型廣告發(fā)布裝置——滾動畫布廣告控制系統(tǒng)。這種新型滾動畫布廣告控制裝置是將五幅畫面連接起來裝在露天燈箱中，畫布用電動機(jī)拖動，可上下進(jìn)行循環(huán)顯示，信息量大，動態(tài)效果好，可以對多種商品進(jìn)行介紹或宣傳，在街頭構(gòu)成一道風(fēng)景線的同時也適用于大商場中對商品信息以及銷售情況進(jìn)行介紹。畫布可以定期更換，方便不同商品需要。
 在畫布循環(huán)運行過程中，各個畫布畫面出現(xiàn)的時間都保持一致，展示一定的時間后再改變到下一序號的畫面。PLC靠軟件程序?qū)?幅畫面的運動進(jìn)行控制，并克服了自動運行中會遇到的各種問題，保證畫布按要求正確運行。此外，該控制裝置還具有手動/自動切換、定時開/關(guān)機(jī)、斷電保持及故障診斷并報警等功能。
關(guān)鍵詞：滾動畫布廣告；可編程序控制器（PLC）；自動運行；故障報警

Abstract
 The thesis introduces one kind of the canvas rolling from the programmable controller (PLC) , infrared sensor , electric motor for new model advertisement that the main component composes announces a device advertisement control device mainly. That advertisement is equipped with this new model rolling canvas under the control of is in open-air lamp case with five tableaux link dress , canvas uses electric motor to drag moving , may carry out circulation display , amounts big , dynamic information effect about well, simultaneous being able to carry out the line introducing or propagating the scenery composing one, in street on diversified commodities introduces that in being unable to apply to market big to being in progress as well as merchandise news selling condition. Canvas is not bad change at the regular intervals , be unlike conveniently commodity need.
 Circulation work process is middle in canvas, each canvas tableau the time appearing all keeps the tableau changing again to time as soon as serial number after showing certain time consistently. And PLC is in progress to 5 tableaux motion by the software program under the control of, have overcome an automation running middle various problem that can come across , have ensured that canvas works according to demanding correctly. Besides, should control a device having hand movement/ the automation changes shut-down , interruption of power supply by all means , holds at the regular time/ to keep functions such as reaching the malfunction diagnose and giving an alarm.
Keywords: Canvas rolling advertisement; Programmable Logic Controller(PLC); The automation works; Malfunction give an alarm
