摘要随着信息化时代进程的加快，人们对于智能防盗的要求越来越高，一般的防盗措施已经不能满足日常需求，高性能的防盗报警器受到了广大民众的喜爱。本论文讲述了智能化光电防盗报警的研究意义，设计并实现了针对家庭、办公室、仓库、实验室等重要场合的红外防盗报警系统。系统由硬件设计和软件设计两部分构成。硬件系统由红外发射电路、红外接收电路、单片机控制电路、声光报警电路、按键设置模块电路等部分组成。当有人进入监控区域时，热释电红外线传感器会探测到人体发出的红外辐射并转变成为微弱的电压信号，经放大后输入到单片机，启动声光报警系统。软件系统主要使用C语言编写和调试控制程序，给出了相关的程序流程图。该报警系统误报率低，使用安全可靠，成本低廉，具有很强的使用价值。关键词：单片机；热释电红外传感器；报警电路；智能防盗AbstractWiththecontinuousdevelopmentandprogressofsociety,peoplehavemoreandmoreattentiontosecurityissuesontheproperty,nowlifealsohaveawiderangeofsecurityproducts,somecanprotectthepersonalsafetyofotherscanprotectthepropertysafety,thedesignisaccordingtotheshowsetamicrocontrollerbasedintelligentresidentialburglaralarm,canthehousepropertysafety.Intelligentanti-theftalarmsystemofthisdesignismainlyrealizedinthehousewhennoonecansetdon'topen,thehouseisinamonitoringstate,whenasensordetectswhensomeoneentersthethiefintothehouse,thecontrolsystemwillcontrolthealarmdeviceforalarm.Throughsearchingrelatedliteraturesummaryideasinthedesignprocessdesign,thedesignisdividedintotwoparts:hardwaredesignandsoftwaredesigninthedesign:inhardwaredesignismainlybasedonthedesigntaskofthehardwarediagramofthewholesystemdesign,hardwarecircuitdiagramisdesignedaccordingtothediagramofeachmodule,includingtheMCUmodulecircuit,pyroelectricsensormodulecircuit,alarmcircuitandkeymodulesettingmodulecircuitetc..ThesystemmainlyusestheClanguagetechnologytodesignanddebugthesoftwarecontrolprogram.Afterthetestofhardwareandsoftware,thephysicalcircuitboardisdesigned.Thisdesignhastheimportantusevalueinthelife,andthedesigncostislow,thevolumeissmall,mayuseflexibly.Keywords:singlechipmicrocomputer;pyroelectricinfraredsensor;alarmcircuit;intelligentanti-theft目录摘要................................................................................................................................IAbstract..........................................................................................................................II第1章绪论................................................................................................................11.1研究背景..........................................................................................................................11.2防盗报警系统在国内外的发展.......................................................................................11.3本文的主要内容..............................................................................................................21.4论文的组织结构..............................................................................................................21.5本章小结............................................................................................................................3第2章系统整体方案设计........................................................................................42.1系统功能..........................................................................................................................42.2系统总体结构设计..................
