【正文】 基于 51 單片機的智能 LED 照明控制系統(tǒng)設計摘 要 隨著社會的發(fā)展人們對生活質(zhì)量的要求越來越高，照明在能耗中所占的比例日益增加,因而照明節(jié)能也日顯重要?，F(xiàn)在國內(nèi)外普及使用的節(jié)能開關基本有聲控型、觸摸型、感光型等。這幾種開關各有自己的弊端，如聲控型不適合環(huán)境嘈雜場所、感光型開關在無人期間不能自動關閉。本設計通過 AT89C51 單片機結(jié)合 LED 照明技術、紅外傳感技術、光感技術、延時技術、處理等技術來實現(xiàn)對照明設備的智能控制。單片機通過繼電器控制照明設備的打開或者關閉、通過光照檢測電路對照明設備周邊亮度進行檢測，如果亮度不夠則單片機同時檢測 BIS0001 芯片是否采集到了人體熱釋電傳感信號，根據(jù)有無人體熱釋電傳感信號單片機立刻控制照明設備打開或關閉。關鍵詞： 單片機；傳感器；BIS0001；照明控制；節(jié)能 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 energysaving 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 can39。t shut automatically. This design bined 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. Microputer 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 microputer 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.
