PAGE\*MERGEFORMATI摘要随着互联网技术带动下的物联网的发展，智能家居逐渐开始迅猛发展。照明作为家庭用电中的重要部分，智能照明也拥有广阔的发展前景。而且随着人们对能源节约的越来越深入人心的认识，设计一种可以随着光照强度的变化来调节自身亮度的照明设备显得很有必要。针对这一问题，本设计采用光照传感器模块采集环境光照强度，然后利用STC89C51单片机对灯光亮度进行控制，完成了光照强度的实时检测与显示，同时可对灯光进行相应的亮度调节，完成了各功能模块的硬件电路设计和软件程序编写，最后用Proteus进行了模拟仿真。仿真结果表明该设计实现了光照强度的实时检测与显示并能对灯光亮度进行适当调节。关键词：智能照明；光照强度检测；STC89C51；灯光自动控制；PAGE\*MERGEFORMATIIAbstractWiththedevelopmentofInternettechnology,thesmarthomeisbeginningtodeveloprapidly.Asanimportantpartofthehousehold,intelligentilluminationalsohasahugedevelopmentprospect.Andastheunderstandingofenergysavingisdeeplyrootedinpeople’smind,designingakindoflightwhichcanchangeitslightintensitywiththesurroundingisverynecessary.Inordertosolvethisproblem,thisdesignusesthelightsensormoduletocollectenvironmentallightintensityandthenuseSTC89C51microcontrollertocontrolthelightbrightness.Completedthereal-timedetectionanddisplayforthelightintensity,andtoadjustthebrightnessofthelightingaccordinglyasystemofthedesignofthehardwaresystemandsoftwareprogram.AfterthesimulationwiththeProteus.Thesimulationresultsshowthatthedesignrealizesthereal-timedetectionanddisplayofthelightintensityandcanadjustthebrightnessofthelight.Keywords：Intelligentlighting；Lightintensitytest；STC89C51；AutomaticlightingcontrolPAGE\*MERGEFORMATIII目录TOC\o"1-3"\h\uHYPERLINK\l_Toc12988摘要PAGEREF_Toc12988IHYPERLINK\l_Toc24462目录PAGEREF_Toc24462IIIHYPERLINK\l_Toc224071绪论PAGEREF_Toc22407-1-HYPERLINK\l_Toc94011.1课题研究的背景及意义PAGEREF_Toc9401-1-HYPERLINK\l_Toc232991.2国外研究现状PAGEREF_Toc23299-2-HYPERLINK\l_Toc169221.4本设计主要内容PAGEREF_Toc16922-3-HYPERLINK\l_Toc103482方案分析PAGEREF_Toc10348-4-HYPERLINK\l_Toc267262.1光照传感器的方案分析PAGEREF_Toc26726-4-HYPERLINK\l_Toc160262.2调光方式的方案分析PAGEREF_Toc16026-4-HYPERLINK\l_Toc278443硬件设计PAGEREF_Toc27844-6-HYPERLINK\l_Toc139233.1硬件选型及电路设计PAGEREF_Toc13923-6-HYPERLINK\l_Toc271083.1.1单片机PAGEREF_Toc27108-6-HYPERLINK\l_Toc1
