基于51单片机智能LED照明控制系统设计摘要伴随社会发展人们对生活质量要求越来越高，照明在能耗中所占百分比日益增加,因而照明节能也日显主要。现在国内外普及使用节能开关基本有声控型、触摸型、感光型等。这几个开关各有自己弊端，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。本设计经过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智能控制。单片机经过继电器控制照明设备打开或者关闭、经过光照检测电路对照明设备周围亮度进行检测，假如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，依照有没有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。关键词：单片机；传感器；BIS0001；照明控制；节能AbstractWiththedevelopmentofsocietypeopleofthequalityoflifeindemandishigherhigher,lightingintheproportionofenergyconsumption,thusincreasingilluminationenergyconservationalsomoreandmoreimportantly.Nowuniversaluseenergy-savinswitchathomeandabroadhavesonicbasictype,touchtype,photographictypeandThisseveralswitchhavetheirowndisadvantages,suchassonictypeisnotsuitabenvironmentalnoisyplaces,photographicswitchinoneperiodcan'tshutautomaticaThisdesigncombinedbyAT89C51LEDlightingtechnology,infraredsensingtechnology,lightsensortechnology,thedelaytechniqueandprocessingtechnologytorealizetheintelligentcontroloflightingequipment.Microcomputercontrolslightingequipmentopenorclosed,bytherelay,throughthelightdetectioncircuitforlightingequipmenttesting,ifsurroundingbrightnessisnotenoughthenmicrocomputerdetecttheBIS0chipwhethercollectedtohumanpyroelectricsensingsignals,accordingtowhetherpyroelectricsensingsignalsmicrocontrollerredirectedimmediatelycontrollightingequipmentopenorclosed.Keywords:microcontroller;sensor;BIS0001;lightingcontrol;energy-saving目录摘要................................................................IABSTRACT............................................................III前言................................................................11概述................................................................21.1课题研究背景....................................................21.2课题研究目标与意义............................................21.2.1良好节能效果和延长灯具寿命................................21.2.2改进工作环境，提升工作效率..................................21.2.3提升管理水平................................................31.2.4很好投资收益效果.........................................
