【導(dǎo)讀】管顯示和模擬電梯的升降，采用按鍵假定電梯當前所在樓層。隨著國內(nèi)經(jīng)濟的發(fā)展及人口向都市集中,使都市的建筑物普遍朝高層化發(fā)展。們的生活中起著舉足輕重的作用。電梯已不僅是一種生產(chǎn)環(huán)節(jié)中的重要設(shè)備,更是一種人們。梯控制類型，這種控制使用繼電器數(shù)量大,保護連鎖觸點多。采用單片機構(gòu)成控制系統(tǒng),不但可以大。大降低成本,而且做成專用控制系統(tǒng),程序被固化,加強了保密性,提高了可靠性。實際應(yīng)用時，可以采用精密紅外發(fā)光對管作為檢測。采用8位LED靜態(tài)顯示。電路用來實時顯示轎廂所在的位置，并用74LS164作為顯示電路的驅(qū)動部分。利用交流接觸器控制電動機正反轉(zhuǎn)從而控制電梯的上升與。當電梯到達要求的樓層時，電機停止運行并進行服務(wù)。當電梯上升或下降過程中，只響應(yīng)同方向的呼喚響應(yīng)。為檢測電路對電梯的橋廂位置進行準確定位校驗，實時監(jiān)測電梯所在樓層。線圈通電，則使交流接觸器主觸點KM1閉合，電動機正轉(zhuǎn)。
