基于RFID应用的IC卡设计-毕业设计

基于RFID应用的IC卡设计系（部）：信息科学与技术系专业班：电子信息工程0602班姓名：李俊杰学号：20061186044指导教师：胡长阳2010年4月II基于RFID应用的IC卡设计ICCard-basedRFIDApplicationDesignI摘要近年来，自动识别技术发展迅速，尤其是随着电子技术的高速发展和制造技术的不断进步，采用无线电和雷达技术实现的射频识别技术发展极为迅速，在物流系统、商业贸易、门禁防盗、识别技术和医学应用等领域中得到了极为广泛地支持和应用。本文绪论部分描述了IC卡的发展和现状，第一章说明了本次设计的主要工作和任务。明确了任务之后，第二章首先介绍了IC卡系统，即IC卡和读卡器的工作原理，然后进行了设计方案的选择与论证，决定采用AT89C2051单片机作为系统控制器而非FPGA，接着描述了本次非接触式IC卡的设计方案并给出了IC卡硬件结构图。在第三章依次介绍了IC卡系统硬件部分的设计，即天线的制作、整流电路、稳压电路、微处理器电路、开关电路。第四章介绍了IC卡系统软件部分的设计，首先就本次设计所要用到的单片机基础知识做了详细的介绍，这其中包括定时控制寄存器、工作方式寄存器、中断允许控制寄存器、串行口寄存器以及串行通信控制寄存器，然后具体阐述了IC卡上的单片机编程思想，最后是本次设计所用应答器发码程序。关键词：非接触式IC卡阅读器AT89C2051射频识别IIAbstractInrecentyears,automaticidentificationtechnologydevelopedrapidly,especiallywiththerapiddevelopmentofelectronictechnologyandmanufacturingtechnologycontinuestoprogress,usingradioandradartechnologytoachieverapiddevelopmentofRFIDtechnologyinlogistics,commerceandtrade,accesscontrolsecurity,identificationtechnicalandmedicalfieldsofapplicationareextremelybroadsupportandapplications.IntroductionThissectiondescribesthedevelopmentandcurrentstatusofICcards,thefirstchapterdescribesthedesignofthismajorworkandtasks.Definedthemission,thesecondchapterintroducestheICcardsystem,thatis,ICcardandcardreaderworks,thenthedesignchoicesandarguments,decidedtouseAT89C2051MCUasasystemcontrollerratherthantheFPGA,andthendescribeofthisnon-contactICcardandthedesignofICcardsaregiventhehardwarechart.Inthethirdchapterintroducesthehardwareofthesystemfollowedbythedesign,thatis,theproductionoftheantenna,rectifiercircuits,voltageregulatorcircuits,microprocessorcircuits,switchcircuits.Thischapterdescribesthedesignofsoftwarecomponents,firstofallusethisdesigntothebasicknowledgeofSCMmadeadetailedintroduction,whichincludestimingcontrolregister(TCON),workregister(TMOD),interruptedtoallowcontrolregister(IE),serialcommunicationserialportregistersandcontrolregisters,andthenexpoundsontheICcardmicrocomputerprogrammingideasand,finally,thisdesignmadewithtranspondercodeprogram.Keyword:non-contactICcardreaderAT89C2051radiofrequencyidentificatio2目录摘要...........................................................................................................................ⅠAbstract:.....................................................................................................................Ⅱ绪论...........................................................................................错误!未定义书签。1.本课题设计的主要工作和任务................................................................................42．IC卡系统方案设计与实现....................................................................................52.1IC卡介绍................................................................................................................52.2读卡器基本原理......................................................................................................52.3总体方案论证..........................................................................................................62.3.1各模块方案的选择与论证..................................................................................62.3.2总体方案设计......................................................................................................63系统硬件设计与实现................................................................................................83.1天线的制作..............................................................................................................83.1.1天线的类型...........................................................................................................83.2整流电路..................................................................................................................93.3稳压电路................................................................................................................103.3.1电路原理.............................................................................................................103.3.2元件资料.............................................................................................................103.4微处理器电路........................................................................................................113.5开关电路................................................................................................................143.5.1元件资料............................................................................................................143.5.2电路原理.............................................................................................................143.6IC卡系统完整电路图...........................................................................................154软件设计..................................................................................................................164.1单片机基础知识介绍............................................................................................164.1.1定时控制寄存器（TCON）..............................................................................164.1.2工作方式寄存器（TMOD）............................................................................164.1.3中断允许控制寄存器（IE）..............
