摘  要
本研究针对教室灯光的控制方法，尤其是教室灯光的智能控制方面的发展现状，分析了教室灯光智能控制的原理和实现方法，提出一种用热释电红外传感器和光照检测相结合的智能照明控制系统。
    本系统以AT89C52单片机作为教室灯光控制器的核心，采用热释电红外人体传感器检测人体存在，采用光敏电阻构成的电路检测环境光的强度，根据实际条件，系统通过对室内是否有人和光线强弱的识别和智能判断，以完成对教室灯光的智能自动控制，实现教室用电设备的合理控制和管理，节约电能以及改善教学管理。系统还有报警、准确的时间和日期显示等功能。
本系统软件设计采用C语言编制，运用模块化结构设计、条理清晰、通用性能良好，便于使用者改进和扩充。

Design of Automatic Controller to Classroom Light
Based on Single Chip Computer

Abstract
Currently light intelligent control systems are not efficiently used in the classroom ,In order to improve the system ,based on the theory of the light control and current methods of how to keep control ,a project of intelligent–illuminating control combined pyroelectric infrared transducer with illumination detection is provided .
     This classroom light intelligent control system is developed country ,which machine of AT89C52 is a core part ,and the environment of development is better than before .This system can satisfy the following functions ,such as controlling the circuit of illumination ,testing and processing daylight signal ,testing and processing the signal of human body that illuminates the back track exists ,reporting to the warning devices ,etc. In order to satisfy these functions ,the system adopted the homologous methods respectively ,and to the gearing of the system ,analyzing how to install ,test and run the system .achieve the realization of Colleges and Universities classroom equipment ,the rational use of electricity ,saving energy and improving teaching and learning management purposes .System also has the additional functionality, For example, alarm, accurate shows the time and date.
     This system software was developed based on C language ,Its corporality is very good and easy to improve and expand .It could be used to develop larger-scale system with more prefect performance .
