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2009527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f1.443/R9R10R11C1。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.Connectasnonstablestatemultivibratorpattern,itsoscilationfrequencydeterminedbyR11,R9,C1generallyaccordingtof1.443/R9R10R11C1.Keywordswelcominggustsofelectron,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............................................................................................165.4.4录放音的操作方式............................................................................175.4.5应用线路图.........................................................................................185.4.6TDA2822功放集成电路...................................................................186模特动作控制模块..................................................................................................207整体电路图..............................................................................................................208印刷电路板..............................................................................................................229结束语......................................................................................................................19谢辞..............................................................................................................................20参考文献......................................................................................................................21
