摘要本题设计一个光照强度自动检测、显示、报警系统，实现对外界三种不同条件下光强的分档指示和报警（弱、适宜、强）。使用光敏电阻光照强度的测量并进行显示，采取单片机对光敏电阻输出变化进行处理转换成数字量再使用数码管进行显示。在单片机上加外围器件三个LED，通过采样到的光照射强度选择，在数码管上显示电压的大小。本设计具有有线路简单、结构紧凑、价格低廉、性能优越等特点。关键词：光照亮度；光敏电阻；单片机；数码管器AbstractSubjecttodesignalightintensitytobeautomaticdetection,display,alarmsystem,therealizationontheoutsidethreedifferentconditionsoflightintensityFenDanginstructionsandalarm(weak,appropriate,stronger).Usephotoconductiveresistanceoflightintensitymeasurementthattakethemonolithicintegratedcircuittochangephotoconductiveresistanceoutputprocessingconvertedintodigitalquantitytousedigitaltubedisplayed.InthesingleperipheraldeviceswiththreeLED,bysamplingthelighttoilluminateintensitychoice,indigitaltubedisplayvoltagesize.Thisdesignhasasimplelines,compactstructure,lowprices,superiorperformanceetc.Characteristics.Keywords:lightbrightness;Photoconductiveresistance;Singlechipmicrocomputer;Digitalpig桂林电子科技大学实训（论文）报告用纸第1页共13页目录引言..............................................................................................................................................................11系统概述............................................................................................................................................11.1设计要求.............................................................................................................................................11.2方案设计.............................................................................................................................................11.2.1方案说明............................................................................................................................11.2.2方案论证............................................................................................................................22硬件电路设计与分析.................................................................................................................32.1单片机最小系统................................................................................................................................32.2光敏电阻的主要特性及参数..............................................52.3光敏电阻接入电路图....................................................62.4数码管显示电路........................................................72.5报警电路..............................................................73软件设计............................................................................................................................................73.1主程序................................................................83.2安装调试及测量数据分析................................................94实训的心得体会............................................................................................................................9致谢.........................................................11参考文献.......................................................12附录.........................................................13桂林电子科技大学实训（论文）报告用纸第1页共13页引言光照强度自动检测显示系统，该系...
