基于51单片机的智能LED照明控制系统设计

I

摘 要

随着社会的发展人们对生活质量的要求越来越高，照明在能耗中所占的比例日益增加,因而照明节能也日显重要。现在国内外普及使用的节能开关基本有声控型、触摸型、感光型等。这几种开关各有自己的弊端，如声控型不适合环境嘈杂场所、感光型开关在无人期间不能自动关闭。本设计通过AT89C51单片机结合LED照明技术、红外传感技术、光感技术、延时技术、处理等技术来实现对照明设备的智能控制。单片机通过继电器控制照明设备的打开或者关闭、通过光照检测电路对照明设备周边亮度进行检测，如果亮度不够则单片机同时检测BIS0001芯片是否采集到了人体热释电传感信号，根据有无人体热释电传感信号单片机立刻控制照明设备打开或关闭。

Abstract

With the development of society people of the quality of life in demand is higher and higher, lighting in the proportion of energy consumption, thus increasing illumination energy conservation also more and more importantly. Now universal use energy-saving switch at home and abroad have sonic basic type, touch type, photographic type and so on. This several switch have their own disadvantages, such as sonic type is not suitable for environmental noisy places, photographic switch in one period can't shut automatically. This design combined by AT89C51 LED lighting technology, infrared sensing technology, light sensor technology, the delay technique and processing technology to realize the intelligent control of lighting equipment. Microcomputer controls lighting equipment open or closed, by the relay ,through the light detection circuit for lighting equipment testing, if surrounding brightness is not enough then microcomputer detect the BIS0001 chip whether collected to human pyroelectric sensing signals, according to whether have pyroelectric sensing signals microcontroller redirected immediately control lighting equipment open or closed.
