教室燈光自動控制系統(tǒng)設(shè)計與實現(xiàn)

1、 本科生畢業(yè)設(shè)計（論文）教室燈光自動控制系統(tǒng)設(shè)計與實現(xiàn)Design and Implementation of Automatic Control System ofClassroom Lights教室燈光自動控制系統(tǒng)設(shè)計與實現(xiàn)[摘 要] 本設(shè)計通過對教室燈光自動控制方法的研究，分析了教室燈光自動控制的原理和實現(xiàn)方法，提出了教室燈光自動控制系統(tǒng)的設(shè)計思路，并在此基礎(chǔ)上開發(fā)了智能控制系統(tǒng)的硬件裝置和相應(yīng)軟件。該設(shè)計以 AT89C51 單

2、片機為控制核心，采用光敏三極管作為探頭對環(huán)境光線強度進行檢測，采用熱釋電紅外傳感器檢測教室有無人進出；根據(jù)此控制系統(tǒng)對環(huán)境光信號和人體存在信號的智能判斷，以及對教室合理開燈的條件，完成對教室照明回路的自動控制，從而達(dá)到節(jié)約電能的目的。另外，采用液晶顯示器顯示教室內(nèi)的人數(shù)，還提供超時報警模塊電路，方便管理人員對教室進行管理等等。采用模塊化結(jié)構(gòu)設(shè)計，具有體積小，控制方便，可靠性高，專用性強，性價比合理等優(yōu)點，可以滿足各類學(xué)校教室燈光控制的要
