来电显示电话机和对讲机的装配调试（陕西理工学院物理与电信工程学院通信1201班，陕西汉中723001）指导教师：龙光利[摘要]学习对讲机和来电显示电话机的工作原理,了解整机安装的一般步骤,并掌握焊接元件的操作程序.对讲机就是把从天线接收到的高频信号经检波还原成音频信号,送到耳机变成音波。电话通信是实现声能与电能相互转换的用户设备。由送话器、受话器和发送、接收信号的部件组成。发话时，由送话器把话音转换成电信号，沿线路发送到对方；受话时，由受话器把接收到的电信号还原成话音。本次实习完成了对讲机和来电显示功能的电话机的装配，并能正常工作。本次试验通过单人单组装配一台对讲机和来电显示功能的电话机，焊接调试，排除遇到的故障。[关键词]对讲机；显示电话机；焊接[中图分类号]TN858[文献标志码]AAssemblyandcommissioningoftelephonecallerIDandwalkietalkie(Grade12,Class1,MajorofCommunicationEngineering，SchoolofPhysicsandtelecommunicationEngineeringofShaanxiUniversityofTechnology,Hanzhong723001,China)Tutor:LongGuangli[Abstract]LearningradioandtelephonecallerIDworks,tounderstandthegeneralstepstoinstallthemachineandaweldingtorchcomponentofoperatingprocedures.RadioisthehighfrequencyfromtheantennatorestoretheaudiosignalbythedetectorsignaltotheheadphonesintoSoundwaves.Telephonecommunicationistoachievesoundenergyandenergyconversionoftheuserequipment.Bythetransmitter,receiverandtransmit,receivesignalcomponents.Speaker,bythetransmitterconvertsthevoicesignal,issenttoeachotheralongtheway;bywords,bythereceivertorestorethereceivedvoicesignal.TheinternshipcompletedradioandtelephonecallerIDfunctionoftheassembly,andcanworkproperly.Throughthisexperiment,onegroupassembledforasingleradioandtelephonecallerIDfunction,weldtesting,precludethefailureencountered.[Keywords]radio;telephone;welding目录1.绪论............................................................11.1课题背景.....................................................11.2电话机的简介及发展历史.......................................11.3收音机的简介及发展简史.......................................22.焊接技术简介.....................................................42.1焊料与焊剂...................................................42.2焊锡机理.....................................................42.3手工烙铁焊剂技术.............................................53.来电显示和电话机的装配...........................................73.1对比元器件清单核对元器件数目及规格..........................73.2元器件的插装................................................73.3来电显示和电话机的原理.......................................73.4来电显示电话的组装及调试....................................93.4.1来电显示电话机的组装...................................93.5总装.......................................................113.6来电显示电话的调试.........................................114.对讲机的装配....................................................124.1对照元器件清单核对元器件...................................124.2识别各种元器件以及其作用...................................124.3对讲机调频调幅的工作原理...................................134.3.1对讲机原理............................................134.3.2FM工作原理...........................................144.4对讲机的组装...............................................144.5调试.......................................................144.5.1调整静态工作点........................................144.5.2调整中频频率...........................................
