摘　　要：针对学校教室照明用电浪费现象,设计基于AT89C52智能照明控制系统,本系统通过AT89C52单片机,首先通过传感器检测教室内是否有人活动,然后通过光强检测电路检测光照强度,其检测信号经过ADC0809转换为可供单片机直接处理的数字信号,根据数字信号自动执行对LED的恒光控制,以实现照明的节能控制.A novel smart lighting control strategy is proposed based on the MCU of AT89C52 for saving electrical energy, especially aiming the severe lighting waste in the classroom. During the whole system operation, the light intensity detection circuit will not be generated unless the system has detected the people＇ s activity via the sensor. The detection signal can be transformed into the digital signal that can be processed directly by ADC0809, and MCU can control the constant LED light automatically by the digital signal. Finally, the purpose of the lighting energy conservation control can be realized.
