用于地下停车库的智能照明电路

Intelligent Lighting Circuit for Underground Parking

随着社会经济的不断发展,人们越来越重视节能和环保。传统的照明方式能耗高、资源浪费严重,不利于节能环保。本文以智能控制及节能技术为基础,利用光敏电阻、红外传感器和声控传感器检测环境信息,采用STC89C52作为处理器,利用BTN7971全桥驱动驱动LED灯,利用AD转换获取光照强度后转化为LED灯相应的亮度,达到照明电路智能控制的目的。

With the continuous development of the social economy,people pay more and more attention to energy conservation and environmental protection. The traditional lighting methods have high energy consumption and serious waste of resources,which is not conducive to energy conservation and environmental protection. This article is based on intelligent control and energy saving technology,using photoresistance,infrared sensor and sound control sensor to detect environmental information,using STC89 C52 as a processor,using BTN7971 full bridge drive to drive LED lights,using AD conversion to obtain light intensity and convert to the corresponding brightness of LED lamp,achieves the purpose of intelligent control of lighting circuit.
