摘要随着科技与生活质量的提升，现代生活的节奏加快，盗窃、入室抢劫、火灾等事件也随之增加，这毫无疑问地对社会的安定和人民的生活带来了很大的影响。人们在繁忙的生活中，不只是追求能有一个舒适的生存环境，更重视自己的生命和财产安全。因此，选择一种科学而又安全的方式来保护自己显得尤为重要，防火防盗报警器便成为目前需求量最大也最为实用的一种防护装置。本次课题是基于智能住宅安全防护设计的一款具有误报率低、可靠性高、使用方便、性价比高的防火防盗报警器。在本设计中，使用的是MCS-51系列单片机，具体的型号是AT89S51，利用热释电红外探测器HC-SR501和雷达式微波探测器XYC-WB-DC双重监测盗情，在放火方面，主要从温度和气体浓度及烟雾方面进行入手，分别使用DS18B20和MQ-2来实现所需要的功能，并结合数字语音录放电路、GSM电路、LCD显示电路以及其他一些辅助电路实现火情盗情的实时语音拨号报警，相较于传统防火防盗报警器，大大提高了监测的准确度以及防护效率，而具有更高的实时性、可靠性。关键词：智能报警；防火防盗；AT89S51；传感器；语音拨号ABSTRACTWiththegradualimprovingofthescienceandtechnology,thequalityoflifehasbeenbetter,andtherhythmofmodernlifeisgettingfasterandfaster.Atthesametime,thetheft,robbery,fireandotherincidentsarebecomingmoreandmore.Thereisnodoubtthattheseeventshavebroughtagreatimpactonthestabilityofpeople'slives.Inthisbusysociallife,peopleshouldnotbesatisfiedwiththecurrentsituation,acomfortableenvironment,buttheypaymoreattentiontotheirownsecurityoflivesandproperty.Therefore,itisveryimportanttochooseascientificandsafewaytoprotectyou.Thefirealarmsystemwillbecomethebiggestdemandandmostpracticalkindofprotection.Thisdesignisanalarmwithlowfalserate,highreliability,andeasytouse.Thiscost-effectivefireproofandtheftproofalarmsystemwasbasedonintelligentresidentialsecurityprotection.ThecoreisMCS-51seriesmicrocontroller(AT89S51),andthesystemusesapyroelectricinfraredsensors(HC-SR501)andaradarmicrowavedetector(XYC-WB-DC)tomonitorthetheft,andusesthesmokesensors(MQ-2)andtemperaturesensors(DS18B20)tomonitorthefire.Atthesametime,itcombinedwithdigitalvoicerecordingcircuit,andGSMcircuit,alsotheLCDdisplaycircuitandotherauxiliarycircuitcanachievethefirealarmvoicedialing.Comparedwithtraditionalfireandtheftalarmsystem,thisdesignhasimprovedtheaccuracyofmonitoringandtheefficiency,alsothealarmsystemhashigherreliability.Keywords:IntelligentAlarm;FireproofandTheftproof;AT89S51;Sensor;VoiceDial目录第一章绪论...............................................................................................51.1研究的目的和意义..........................................................................................51.2国内外研究现状..............................................................................................61.3我国家庭报警系统的发展趋势与展望..........................................................71.4论文主要工作..................................................................................................81.5本章小结..........................................................................................................8第二章系统整体方案的分析与设计.......................................................92.1智能语音报警系统的要求..............................................................................92.2系统整体设计思路..........................................................................................92.2.1传感器的选择.......................................................................................92....
