智能楼宇照明控制系统设计

Design of lighting control system for intelligent building

文章把单片机技术和脉宽调制技术(PWM)结合起来,设计一套智能化楼宇照明控制系统,实现灯光光强的自动调节,即在不改变PWM方波周期的前提下,利用单片机控制PWM的占空比,来改变电压的大小实现照明亮度的调节。该系统可以实现自动调节亮度和异常报警等功能,提高照明系统的节能性和智能性,进而提高智能楼宇自动化水平。

A multi-functional intelligent building lighting control system is designed by combining the single-chip microcomputer technology and PWM dimming technology in this paper, which can realize the automatic adjustment of light intensity. That is, on the premise of not changing the PWM square wave period, using the single-chip microcomputer to control the duty cycle of PWM to change the voltage to realize the adjustment of lighting brightness. The system can realize the functions of automatic adjustment of brightness and abnormal alarm, improve the energy saving and intelligence of lighting system, and then improve the automation level of intelligent buildings.
