1、摘要車庫門全自動門控裝置，其特征在于設(shè)有置于車庫內(nèi)和車庫外的主控制器以及安裝在車輛內(nèi)的密碼標(biāo)識器，主控制器由單片機(jī)、315M無線接收器、解碼器、鍵盤、數(shù)碼管和紅外對管組成，密碼標(biāo)識器由無線發(fā)射器和編碼器。PT2262與PT2272地址和數(shù)據(jù)狀態(tài)一模一樣，PT2262電源端平時斷開，若快到了車庫門則按下按鈕通電，編碼器PT2262將地址和數(shù)據(jù)通過無線發(fā)射模塊發(fā)射，同時無線接收器的輸出端接解碼器的輸入端，解碼器的輸出端VT接單片機(jī)的P3.3，若數(shù)據(jù)完全正確則車庫內(nèi)的單片機(jī)啟動電機(jī)開啟車庫門，同時紅外對管感應(yīng)次數(shù)計數(shù)，出車庫門后門自動下降，也可以通過按鈕屏蔽紅外對管，實現(xiàn)手動放下車庫門。之
