基于ARM的智能门禁系统设计

攀枝花学院本科毕业设计（论文）摘要I摘要门禁系统作为安防系统中的一个重要部分，随着人们的生活水平和工作的质量的提升，其技术要求也得到了相应的提升。同时在楼宇自动化中门禁系统也得了很多的重视。它以计算机技术为主体，涉及了电子、机械、光学、通讯技术、生物技术等多种技术用来有效的对出入口进行控制，并且限制出入人员的权限。计算机系统通过门禁锁实现对出入口的控制，而最多只需要一个人在中心监控室实现有必要的人为控制。本课题就是以ARM为主控制器，将嵌入式技术和射频识别技术应用到门禁系统中，利用嵌入式系统丰富的控制器资源、对实时多任务有很强的支持能力、可扩展的处理器结构方便以后功能的完善，同时射频技术来检测IC卡，通行的人用IC卡来获得进入的权限。关键字：门禁系统，嵌入式技术，身份识别技术攀枝花学院本科毕业设计（论文）ABSTRACTIIABSTRACTAccesscontrolsystemasanimportantpartofthesecuritysystem,withtheenhancementofpeople'slivingstandardsandthequalityofwork,technicalrequirementshasalsobeenacorrespondingincrease.Accesscontrolsystemsinbuildingautomationalsogotalotofattention.Computertechnologyasthemainbodyinvolvedintheelectronic,mechanical,optical,communicationstechnology,biotechnologyandothertechnologiesusedtocontroltheimportandexport,andtolimitaccesspermissions.Computersystemtocontroltheimportandexportthroughaccesscontrollockuponlyonepersoninacentralcontrolroomtoachievethenecessaryhumancontrol.Thesubjectisthecontroller,ARM-basedembeddedtechnologyandradiofrequencyidentificationtechnologytotheaccesscontrolsystem,embeddedsystemcontroller,astrongabilitytosupportreal-timemulti-tasking,scalableprocessorsstructuretofacilitatefutureimprovethefunctionoftheradiofrequencytechnologytodetectICcard,ICcardaccesstogetpermissiontoenter.Keywords:Accesscontrolsystem，embeddedtechnology，IDtechnology攀枝花学院本科毕业设计（论文）目录目录摘要.................................................................................................................................IABSTRACT....................................................................................................................II第一章绪论.....................................................................................................................11.1课题背景和意义.....................................................................................................11.2门禁系统的发展和国内外现状...............................................................................11.3论文研究的内容和工作...........................................................................................2第二章门禁系统技术的介绍.........................................................................................42.1RFID射频识别技术的介绍......................................................................................42.2基于ARM平台的嵌入式系统的介绍.........................................................................52.2.1ARM技术的介绍........................................................................................................52.2.2嵌入式系统概述.......................................................................................................6第三章总体设计和软硬件平台的选择.........................................................................93.1系统总体设计.........................................................................................................93.2硬件平台的选择.....................................................................................................93.2.1S3c6410芯片介绍......................................................................................93.2.2MFRC500射频读写芯片...........................................................................113.3软件平台的选择...................................................................................................133.3.1选择Linux操作系统的理由.......................................................................143.3.2bootloader的选择....................................................................................153.3.3文件系统的选择........................................................................................16第四章系统详细设计与实施.......................................................................................184.1嵌入式Linux开发环境的搭建.............................................................................184.2主机开发环境的搭建和系统的移植......................................................................184.2.1搭建主机的开发环境.................................................................................184.2.2U-boot的编译...........................................................................................184.2.3内核的定制...............................................................................................194.2.4文件系统的制作........................................................................................22第五章应用软件的设计...............................................................................................245.1软件设计的总体思路...........................................................................................245.2通过协议编写程序...............................................................................................26结论.............................................................................................................................28参考文献.........................................................................................................................29附录...............................................................................................................................30致谢..........................................................................................
