基于AT89S51和RE200B的教室照明节能控制系统设计

为了实现对教室照明系统的智能控制和节约用电,设计了基于单片机和热释电红外传感器的教室照明节能控制系统.该系统以AT89S51单片机作为主控芯片,利用人体的恒温特性,采用热释电红外传感器RE200B探测人体的存在,用光敏电阻检测当前环境的光照强度,对教室照明灯实行分区控制的策略,从而实现了对教室照明系统的智能和节能控制.

Design of Classroom Lighting Energy-Saving Control System Based on AT89S51 and RE200B

In order to control the classroom lighting system intelligently and save electrical energy,a classroom lighting control system based on microcontroller and pyroelectric infrared sensor is proposed.In this system,microcontroller AT89S51 is adopted as the control kernel,and pyroelectric infrared sensor RE200B is adopted to detect the existence of human body by the constant temperature of human body,and photoconductive resistance is used to measure the environment temperature.At the same time,the strategy of district control is adopted.At last,the intelligent control and energy saving are realized by this control system.
