基于STC89C52单片机的门禁锁设计EntranceGuardCombinationLockDesignControlBasedonSTC89C52摘要根据现代人对生活中安保问题的追求，我所选择的方案是基于单片机的门禁指纹密码锁系统。以STC89C52单片机为主模块，经过指纹模块完成读取指纹、存储指纹、对比指纹，并通过液晶显示信息结果，同时增加直流继电器与发光二极管模拟开锁的动作再加上GSM模块短信通知以此来实现门禁的系统设计。在科技飞速发展的今天，生活中有很多密码需要人们记忆，这对于大多人来说是十分不方便再加之各种入室抢劫按键发生，普通的门禁设计已经完全不符合人们的要求。而根据每个人都是一个不同的个体以及拥有不同的生理特征可以帮助我们解决这个问题。本系统具有稳定、操作方便、体积较小而且安全性能更优，适合家庭及规模较小部门使用。关键词：指纹电子密码；GSM；STC89C52AbstractAccordingtothemodernpeople'spursuitofthesecurityproblemsinourdailylife,theschemeIchooseistheaccesscontrolfingerprintcodelocksystembasedonsinglechipmicrocomputer.ThemainmoduleisSTC89C52singlechipmicrocomputer,andthefingerprintisread,storedandcomparedthroughthefingerprintmodule.ThesystemdesignofaccesscontrolisrealizedbyLCDdisplayinformationresult,atthesametimeaddingtheactionofDCrelayandlight-emittingdiodeanalogunlockingandGSMmoduleshortmessagenotificationtorealizethesystemdesignofaccesscontrol.Today,withtherapiddevelopmentofscienceandtechnology,Therearealotofpasswordsinlifethatpeopleneedtoremember,whichisveryinconvenientformostpeople,coupledwithallkindsofburglarybuttonoccurrence,commonentranceguard.Thissystemisstable,easytooperate,andcanhelpussolvethisproblemaccordingtothefactthateveryoneisadifferentindividualandhasdifferentphysiological-I-characteristics.Smallsizeandbettersafetyperformance,suitableforhomeandsmall-scaleuse.Keywords:Intelligentdesklamp;pyroelectricity;STC89C5-II-目录摘要..............................................................................................................................................IAbstract.......................................................................................................................................I1序言............................................................................................................................................11.1指纹密码锁研究背景及意义..................................................................................................11.2指纹密码锁的发展前景..........................................................................................................12毕业设计内容............................................................................................................................22.1毕业设计内容及实现功能......................................................................................................22.2系统分析.................................................................................................................................23系统硬件设计............................................................................................................................33.1单片机最小系统......................................................................................................................33.1.2复位电路..............................................................................................................................53.2液晶显示模块.....................................................................................................
