摘  要
 随着人民生活水平的提高和光源的发展，人们对照明的要求越来越高，要求利用光照营造和谐的气氛,舒适的环境，创造一种动态的效果以及操作上的简便。我国大部分高校的教室照度都高于标准，加之人为的浪费所造成不必要的支出，从节约资源、对社会贡献和节省高校经费支出多方面考虑，高校教学楼照明灯的智能化管理改革势在必行，教室灯光智能控制系统的研发对于公共教室灯光节能具有非常重要的实用意义。
    本课题主要是针对高校教学楼照明管理中电能浪费的现象，设计了教学楼智能照明系统，通过智能化控制实现节电目标。
 本次设计是以教室监控系统为重点，根据目前高校的教学楼电浪费现象,以AT89C52为核心中央处理器设计教室控制器（其中主要包括光敏传感器，红外传感器设计）。有效地对教室里的用电设备、学生人数以及教室的光照强度等进行监控，通过对光线的强弱和室内是否有人的判断自动实现开关灯,达到节能的目的。

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.
 
 Keywords：pyroelectric infrared transducer; illumination control; energy saving; single chip computer
