太阳能广告灯箱设计与制作毕业论文.doc

本科毕业论文(设计)论文题目太阳能广告灯箱设计与制作学生姓名所在院系机电学院所学专业应用电子技术教育导师姓名完成时间摘要本设计采用新能源太阳能,用太阳能电池给高亮度LED供电,利用单片机技术实现广告灯箱的光电控制、定时控制和节能控制,克服阴天时不能及时照明灯箱、天亮后不能及时关断灯箱电源的现象,避免人工控制带来的长明灯现象,以节约电能。本设计采用时、光双控电路,时控电路用DS1302芯片,光控电路采用光敏传感器,再与单片机结合实现所需功能,使广告灯箱的工作时间更加合理化,更节约能源。关键词太阳能电池,LED,时控电路,光控电路DevelopmentofsolaradvertisinglightboxAbstractThisdesignusesthenewenergysolarenergy,withthesolarcellforthehighluminanceLEDpowersupply,realizestheadvertisementlamphousephotoelectriccontrolusingthemonolithicintegratedcircuittechnology,thetimedcontrolandtheenergyconservationcontrol,overcomeswhenthecloudydaycannotilluminatepromptlythelamphouse,afterthedawn,cannotshutoffthelamphousepowersourcesphenomenonpromptly,avoidslargeoillamplitdayandnightbeforeBuddhastatusphenomenonwhichthemanualcontrolbrings,bysavestheelectricalenergy.Thisdesignuses,thelightdoublecontrolstheelectriccircuit,whencontrolledtheelectriccircuitwiththeDS1302chip,thelightcontrolstheelectriccircuittousethephotosensitivesensor,realizedagainwiththemonolithicintegratedcircuitunionneedsthefunctioncausestheadvertisementlamphousetheoperatingtimeevenmorerationalize,morefrugalenergy.Keywordssolarbattery,LED,Timecontrolcircuit,Lightcontrolcircuit目录1引言............................................................................................................................12系统原理与结构........................................................................................................13太阳能系统设计........................................................................................................23.1太阳能电池......................................................................................................23.2蓄电池..............................................................................................................33.3太阳能控制器..................................................................................................43.3.1蓄电池充电控制基本原理....................................................................43.3.2蓄电池放电控制基本原理....................................................................53.4太阳能电池板的选用.......................................................................................63.5蓄电池选型.......................................................................................................63.6倾角设计..........................................................................................................74硬件电路设计............................................................................................................74.1时控电路..........................................................................................................74.2光控电路..........................................................................................................84.3恒流电路与负载电路......................................................................................84.4显示电路..........................................................................................................94.5单片机最小系统硬件电路设计....................................................................105主要元器件介绍......................................................................................................105.1单片机............................................................................................................105.2LED.................................................................................................................135.3晶振................................................................................................................135.4DS1302..............................................................................错误未定义书签。6软件部分...................................................................................................................157结束语.......................................................................................................................15致谢..............................................................................................................................16参考文献......................................................................................................................17附录1...........................................................................................................................18附录2...........................................................................................................................19附录3...........................................................................................................................20
