proteus:教室自動感應(yīng)照明控制系統(tǒng)

教室自動感應(yīng)照明控制系統(tǒng)是基于單片機對學(xué)校教室照明設(shè)備進行控制和管理，教室亮度的調(diào)節(jié)、自動與手動狀態(tài)的切換。整個系統(tǒng)由紅外對管電路、光線檢測電路、獨立按鍵操作電路組成。單片機可以實現(xiàn)對教室內(nèi)的教室檢測控制元件所采集到的信息的接收、處理，從而可以很輕松的通過自習(xí)學(xué)生人數(shù)對教室光照強度進行實時調(diào)節(jié)。
教室照明節(jié)電控制部分采用STC89C52單片機作為核心控制芯片。教室入口裝有兩個激光傳感器通過高低電平判斷人數(shù)輸出信號。樓道和洗手間采用熱釋電傳感器觸發(fā)電路使LED燈發(fā)亮。
系統(tǒng)實現(xiàn)的主要功能有：
1）紅外對管電路，也是人數(shù)檢測電路，可以對進入教室的人數(shù)進行統(tǒng)計，然后在光線黑暗的條件下，根據(jù)教室的人數(shù)決定照明燈的亮度。
2)光敏電阻檢測光線強度，對照明現(xiàn)場的亮度進行檢測，如果現(xiàn)場亮度符合照明要求，系統(tǒng)應(yīng)關(guān)閉照明設(shè)備實現(xiàn)智能控制。
3)獨立按鍵操作電路，可以切換自動狀態(tài)和手動狀態(tài)。手動狀態(tài)就是可以手動控制教室的照明燈。
4)樓道部分采用熱釋電傳感器檢測該區(qū)域是否有人通過，控制LED燈的開關(guān)。
