全自动电子迎宾机器人设计毕业论文.doc

河南科技学院2009届本科毕业论文（设计）论文（设计）题目全自动电子迎宾机器人设计学生姓名：曹晓丽所在院系：机电学院所学专业：应用电子技术教育导师姓名：田泽正完成时间：2009-5-27摘要本电路可安装在商场、宾馆、舞厅等营业场所的门口，利用红外线检测技术自动识别顾客的进、出方向。客人进门时它会说欢迎光临，同时模特会做出弯腰和伸手的示意动作。客人出门时它又会说谢谢光临，同时做出和上述相同的动作。语音电路发出的语音能给人以愉悦、亲切的感觉。该装置不受情绪和天气冷热的影响，对顾客热情如一。增强顾客对该部门的好感，提高该部门的声誉。它将成为一个无人值守的自动迎宾礼仪小姐。用该装置来代替迎宾小姐，不仅经济，而且十分有趣。自动电子迎宾电路工作原理如附图所示。它由红外振荡器IC1、红外接收器D5及D6、互锁单稳态触发器U12A及U12B和语音存储器IC6和IC7等构成。IC1是一片单时基集成电路NE555，接成无稳态多谐振荡器模式，其振荡频率由R11、R9、C1确定，一般可按f=1.443/(R9+R10+R11)C1。关键词：电子迎宾，语音模块，红外线发射，红外线接收AbstractThiscircuitcanbeinstallentranceinthemarket,hotel,dancehallandsoon.Ituseinfraredexaminetechnologytodistinguishthedirectionofguestcomingandcomingoutautomatic.Whengustcomesin,itsayswelcomepresence,meanwhile,themodulecanmakeactionofbentwaistandputouthand.Whengustcomesout,itwillsaythankpresence,meanwhile,abovemakingsameaction.Thepronunciationcircuitsendingoutvoicecangivepersonjoyfulandcordialimpression.Moreover,moodandweathertemperaturecantaffecttheequipment.Itgivesamecordialtogust.Strengthenthefavorableimpressionofcustomertodepartment.Andimprovesthedepartmentreputation.Itwillbecomeaautomaticwelcomingguestladywithnopersononduty.Usingthisequipmenttoreplacewelcomeguestlady,itisnotonlyeconomicbutalsointeresting.Theworkprincipleofautomaticelectronwelcomingguestcircuitisshowninattacheddiagram.ItconsistsofinfraredoscillatorIC1,infraredreceiverD5andD6,mutuallylockssinglestablestatetriggerU12AandU12B.andpronunciationstorageIC6,IC7IC1isasingletimeintegratecircuitNE555.Connectasnon-stablestatemultivibratorpattern,itsoscilationfrequencydeterminedbyR11,R9,C1generallyaccordingtof=1.443/(R9+R10+R11)C1.Keywords:welcominggustsofelectron,Thepronunciationmodule,Emissionofinfraredradiation,Theinfraredreceive目录1绪论.52方案论证.63系统框图.84电路的工作原理.85模块介绍.105.1电源模块.105.2检测模块.75.2.1红外信号发射模块.75.2.2红外信号接收模块.85.3互锁控制模块.95.3.1电压比较器LM324.95.3.2双四位加法计数器CD4518.105.4语音控制模块.115.4.1主要特性.155.4.2封装形式.165.4.3引脚描述.16
