基于单片机的教室照明控制系统设计 摘 要
随着电子技术的飞速发展，基于单片机的控制系统已经广泛应用于各个邻域。另外，由于楼宇智能化的发展和成熟，基于单片机的教室照明控制系统得到了广泛的普及。
本文根据教室灯光智能控制方面的发展现状，分析了有效的节电控制方案，提出了基于AT89S51单片机的教室照明控制系统。系统采用热释红外人体传感器检测人体的存在，以此来控制照明灯的开启和关闭；利用光敏电阻来检测环境光的强度，以此来调节灯具的亮度；另外，系统还带有键盘及液晶显示，键盘用于输入密码及设置时间参数，液晶显示屏用于显示当前时间及系统提示；系统还可以自主设置教室灯具的开启及关闭时间，关灯前可利用蜂鸣器发出警告。通过对人体存在信号及环境光信号的识别和判断，完成对教室灯具的智能控制，以达到节能的目的。本系统软件采用C语言编制，采用模块化结构设计，条理清晰，便于修改。

The Design of Classroom Lighting Control System Based on Single-chip Microcomputer Abstract
With the rapid development of electronic technology, the system of control based on MCU is widely applied in various fields. What's more,due to the development and maturation of the intelligent building,the control system for classroom lighting based on single-chip microcomputer has been widely popular.
According to the development status of intelligent lighting control in the classroom, analysis of effective power-saving control solution,proposed classroom lighting control system which is based on AT89S51 MCU.This system can control the lamp switch by test and process the signal of human body that illuminates the back track exists;It can adjust the brightness of light by test and process daylight signal; In addition, the system also has a keyboard and LCD,keyboard use to enter passwords and set time parameters, LCD displays the current time and the system prompts;This system also can Independently set up the turn on and off time of lights,it can generate warnings by buzzer before turn off the lights. According to identify and judge the human body existence signal
and the daylight signal, completion of classroom lighting intelligent control to save energy.The microcontroller software was developed based on C language, C language adopts building bloke design,its corporality is very good and easy to change.
