毕业设计题目智能垃圾桶系统的设计姓名许志兴学号20119811系部理工系年级专业2011级电子信息工程指导教师徐丽莎年月日摘要本文设计了一种基于STC89C52RC的多功能垃圾箱控制系统。该系统主要由超声波测距电路、光电感应模块、电机驱动模块和语音报警模块等功能模块组成，以超声波传感器、RPR220光电传感器和单片机为核心，通过传感器采集距离信息，再经过A/D转换让单片机发出指令，如果超声波传感器检测到人与垃圾箱的距离小于设定距离，则垃圾箱自动翻盖，如果RPR220光电检测到垃圾箱已满，系统就会进行语音提示。本系统具有结构简单、性能稳定、操作方便、低成本、智能化等优点，为进一步隔离人与垃圾，防止人感染细菌找到了一个可行的解决方法。关键词:单片机，超声波传感器，RPR220光电传感器，垃圾箱TitleAMultifunctionalBinControlSystemAbstract:ThispaperdesignsamultifunctionalbincontrolsystembasedonSTC89C52RC.Thecoresofthissystemareultrasonicsensor,RPR220photoelectricsensorandsinglechipmicrocomputer(SCM).Itconsistsofpowercircuit,sensorcircuit,clockcircuitandvoicealarmmodule,etc.Usingthesensortocollectdistanceinformation,thentheinformationistobeconversedbyA/D,causestheSCMissuesaninstruction.Iftheultrasonicsensordetectsthatthedistancebetweenpeopleanddustbinissmallerthansetdistance,dustbinlidwouldopenautomatically.IfRPR220photoelectricdetectsthatdustbinischock-full,thesystemwouldissueavoicemessage.Thissystemhasadvantagesofsimplestructure,stableperformance,convenientoperation,lowcostandintelligentization.Andwouldrealizeautomaticflipofdustbin,voicepromptofdustbinbeingchock-fullandregularsprayingdisinfectant.Thusitisafeasiblemethodtocompletelyisolatepeopleandrubbish,andpreventpeoplefrominfectingwiththebacteriaongarbage.Keyterms:singlechipmicrocomputer,Ultrasonicsensors,RPR220photoelectricsensors,dustbin目录TOC\o"1-3"\h\uHYPERLINK\l_Toc123121引言PAGEREF_Toc123124HYPERLINK\l_Toc123001.1选题的依据及意义PAGEREF_Toc123004HYPERLINK\l_Toc196051.2我国垃圾处理现状PAGEREF_Toc196056HYPERLINK\l_Toc207961.3垃圾处理建议PAGEREF_Toc207967HYPERLINK\l_Toc261642系统整体实现PAGEREF_Toc261648HYPERLINK\l_Toc269962.1系统整体实现PAGEREF_Toc269968HYPERLINK\l_Toc226412.2单片机最小系统PAGEREF_Toc226419HYPERLINK\l_Toc91342.2.1STC89C52RC单片机简介PAGEREF_Toc91349HYPERLINK\l_Toc196592.2.2复位电路PAGEREF_Toc1965910HYPERLINK\l_Toc105702.2.3晶振电路PAGEREF_Toc1057011HYPERLINK\l_Toc21189
