摘  要
 隨著人民生活水平的提高和光源的發展，人們對照明的要求越來越高，要求利用光照營造和諧的氣氛,舒適的環境，創造一種動態的效果以及操作上的簡便。我國大部分高校的教室照度都高于標準，加之人為的浪費所造成不必要的支出，從節約資源、對社會貢獻和節省高校經費支出多方面考慮，高校教學樓照明燈的智能化管理改革勢在必行，教室燈光智能控制系統的研發對于公共教室燈光節能具有非常重要的實用意義。
    本課題主要是針對高校教學樓照明管理中電能浪費的現象，設計了教學樓智能照明系統，通過智能化控制實現節電目標。
 本次設計是以教室監控系統為重點，根據目前高校的教學樓電浪費現象,以AT89C52為核心中央處理器設計教室控制器（其中主要包括光敏傳感器，紅外傳感器設計）。有效地對教室里的用電設備、學生人數以及教室的光照強度等進行監控，通過對光線的強弱和室內是否有人的判斷自動實現開關燈,達到節能的目的。

Abstract
 With people's living standards improve and the development of light, people demand more and more lighting, require the use of light create a harmonious atmosphere and comfortable environment and to create one kind of moving effect and operation of the simple. Most colleges and universities in China are higher than the standard classroom illumination, combined with human waste caused by unnecessary expenditure, to save resources and contribution to society and to save many expenses to consider college, university building intelligent lighting management reform momentum must be carried out, the classroom lighting intelligent control system development for energy-saving lights in public classrooms is very important practical significance.
 This topic is mainly for university building lighting energy waste management in the phenomenon, the design of the teaching building intelligent lighting system, intelligent control to achieve energy saving targets through.
 The design is focused on classroom monitoring system, based on current university teaching building electrical waste to AT89C52 core CPU design classroom controller (which include light sensors, infrared sensor). Effectively in the classroom electrical equipment, the number of students and classrooms to monitor the light intensity, light intensity and by whether someone in the judge room automatically switch lights to save energy.
