www.yanziedu.com天津师范大学本科生毕业论文（设计）题目IC卡电子门锁控制系统硬件设计与实现学号02509075姓名胡帼欣专业计算机科学与技术年级2002级学院计算机与信息工程学院完成日期2006年6月指导教师李骊www.yanziedu.comIC卡电子门锁控制系统硬件设计与实现摘要随着科技的进步，以单片机为核心的自动门锁控制系统已经开始进入了人们的生活。本论文着重阐述了以MCS51系列单片机为核心，通过可编程并行接口8255直接控制LCD液晶显示器模块及键盘扫描，并与接触式IC卡读写技术相结合的系统。为保证门锁使用的安全性，系统自动比较IC卡密码和用户输入密码，若输入的密码与系统读出的IC卡密码相同，门锁自动开启若连续输入三次错误的密码，系统自动停止此卡的使用，并及时将报警信号通过RS485串行通信总线传往主控台。本设计的优点是硬件电路简单，软件功能完善，控制系统可靠，具有一定的实用价值。该系统拓展后，可用于其他智能家电的控制，具有好的应用前景。关键词MCS51单片机，接触式IC卡，LCD显示器，电子门锁www.yanziedu.comThehardwaredesignandrealizationofICcardelectronicdoorlockscontrollingsystemAbstractWiththeprogressoftechnology,theautomaticdoorlockscontrolsystemwhichtakesthetheSingleMicroChipComputerasthecoreissteppingintopeopleslives.ThispaperfocusesonthesystemwhichtakestheseriesSingleMicroChipComputerMCS51asthecore,whichcontrolsLiquidCrystalDisplaymodulesandkeyboardscanningthroughthe8255chipdirectly,andcontactstheICcardreadwritetechnology.Inordertoguaranteethesecurityofthedoorlocksuse,thesystemdesignoffersancomparisionbetweentheICcardpasswordandthepasswordwhichtheuserinput.IfinputedpasswordandtheICcardpasswordreadoutonthesystemreadoutaresame,thedoorlockwillbeopenedautomaticly.Ifyouinputwrongpasswordthreetimescontinuously,thesystemwillautomaticallystoptheuseofthecard,andthealarmwillbetransmitedtothekeystationpromptlythroughtheRS485serialtelecommunicationsbusstbus.Theadvantageofthisdesignissimpleinthehardwarecircuits,softwarefunctionalimprovements,thecontrolsystem′sreliablily,andhascertainpractical.Afterthissystemisdeveloped,itcanbeusedinotherintelligentelectricalappliancescontrolandhasagoodapplicationprospect.KeywordsSingleChipMicroComputer,ICcards,LiquidCrystalDisplay,Electronicdoorlockswww.yanziedu.com目录1系统分析............................................................................................................................11.1系统研究的可行性.....................................................................................................11.2需求分析.....................................................................................................................11.3系统整体设计方案.....................................................................................................21.4系统集成.....................................................................................................................32系统硬件整体设计方案....................................................................................................32.1所需功能模块.............................................................................................................32.2外围互连的资源分配示意图.....................................................................................33MCS51系列单片机..........................................................................................................43.1MCS51单片机简介...................................................................................................43.2MCS51单片机的基本结构.......................................................................................43.2.1MCS51单片机的基本组成................................................................................43.2.2MCS51单片机硬件结构特点............................................................................53.3MCS51单片机的引脚及片外总线结构...................................................................63.3.1MCS51单片机芯片引脚描述............................................................................63.3.2MCS51单片机外总线结构................................................................................63.4MCS51与直接控制的外围功能模块互连的资源分配...........................................64接触式IC卡模块的设计与实现......................................................................................64.1IC卡概述.....................................................................................................................64.2IC卡的分类.................................................................................................................64.3接触式IC卡说明.......................................................................................................74.4接触式IC卡引脚图...................................................................................................74.524C01芯片引脚图及介绍..........................................................................................84.6接触式IC卡的应用...................................................................................................94.7IC卡读写的调试.........................................................................................................958255芯片与LCD液晶显示、键盘模块的设计与功能实现........................................115.18255芯片的设计及功能...........................................................................................115.1.18255芯片的引入................................................................................................11
