红外遥控密码锁的设计(自)

毕业设计(论文)论文题目遥控密码锁的设计姓名学号专业班级所在学院指导教师完成时间I遥控密码锁的设计摘要先前的锁具都是机械式的，可是由于时代的进步，机械式的锁具已经慢慢被淘汰，取而代之的是新一代的高科技锁具，具有密码功能的锁具。然而为了革新，同时也为了使锁具多样化，具有实用性，遥控密码锁便应运而生，这不仅是锁具的一个巨大变革，同时预示着人类生活已进入信息化时代。目前遥控密码锁分为两大类：一个是通过无线遥控来远程控制密码锁，另一类是通过红外遥控来远程控制密码锁，这两类密码锁的设计一方面满足了人们对于安全的需求，所以目前很多都用到了遥控密码锁作为门锁、仓库锁，和一些安保行业的锁具。另一方面通过远程控制可以让人们不用到达一个地方就可以实现开锁，这一方面主要都是运用到一些像化学行业因为短时间没有安全措施，但是无法到达并且需要打开某一些门或者机关类的锁具。由此，遥控密码锁在人类生活中产生了巨大的作用，而红外遥控密码锁更优于无线遥控密码锁，作为成本相对较低，而且不容易受到干扰而被人们喜爱。关键词：单片机红外遥控红外接收密码锁IIDesignofintelligentelectroniclightingdevicehenhouseAbstractPreviouslocksaremechanical,butduetotheprogressofTheTimes,mechanicallockhasgraduallybeeliminated,replacedbyanewgenerationofhigh-techlock,whichhasthefunctionofthepasswordlock.Toinnovation,however,atthesametimeinordertomakethediversificationoflocks,practical,remotecontrolcombinationlockthenarisesatthehistoricmoment,itisnotonlythelockofahugechange,atthesametimeindicatesthehumanlifehasenteredtheinformationera.Currentremotecontrolcombinationlockisdividedintotwocategories:oneisthroughthewirelessremotecontrolremotecontrolcombinationlock,anotherkindisthroughtheinfraredremotecontrolremotecontrolcombinationlock,thesetwokindsofcombinationlockdesignontheonehand,meettheneedsofthepeopleforsafety,sonowmanyareusedtoremotecontrolcombinationlockasthelock,lockwarehouse,andsomeofthesecurityindustrylocks.,ontheotherhandthroughtheremotecontrolcanmakepeopledon'thavetoreachaplacecanbeachievedthelock,whicharemainlyappliedtosomeshorttimenosecuritymeasureslikechemicalindustry,butcannotreachandneedtoopensomeclassesorauthoritylocksthedoor.Thus,remotecontrolcombinationlockhasahugeroleinhumanlife,andtheinfraredremotecontrolcombinationlockismorebetterthanthatofthewirelessremotecontrolcombinationlock,asthecostisrelativelylow,andnotsusceptibletointerferenceandlovedbypeople.Keywords:MCUinfraredremotecontrolinfraredreceivingcombinationlockIII目录1绪论........................................................................................................................11.1项目背景...........................................................................................................11.2项目的主要任务............................................................................................11.3国内外研究现状............................................................................................11.4项目设计功能................................................................错误!未定义书签。2硬件电路设计........................................................................................................32.1系统硬件原理图...............................................................................................32.2单片机系统....................................................................................................32.2.1主要特性.....................................................................................................42.2.2管脚说明.....................................................................................................42.2.3振荡器特性.................................................................................................62.2.4芯片擦除.....................................................................................................62.2.5复位电路.....................................................................................................62.2.6振荡电路.....................................................................................................72.3红外接收电路...................................................................................................72.4矩阵键盘...........................................................................................................82.4.1矩阵键盘原理.............................................................................................82.4.2矩阵键盘按键识别方法.............................................................................92.5显示电路...........................................................................................................92.5.1LCD1602引脚连接....................................................................................92.5.2指令集.......................................................................................................112.6开锁电路.........................................................................................................112.6.1电磁继电器的工作原理和特性...............................................................132.6.2电磁式继电器的主要参数.......................................................................132.7报警电路.........................................................................................................133软件设计..............................................................................................................143.1主机接收部分程序设计.................................................................................143.1.1主程序设计...............................................................................................143.1.2中断服务程序...........................................................................................143.1.3解码子程序..............................................
