摘要随着信息技术的飞速发展以及人们生活水平的大幅度提高，人们对住宅的需求已从追求简单的生存空间向着追求质量、功能、服务等多重需求过渡。本文介绍了住宅智能化中的防盗防火报警系统。智能化住宅防盗防火报警系统集防盗防火功能于一体，可实现自动检测与自动电话拨号报警。自动检测是指由红外探测与微波探测器构成的双鉴探测器实现盗情检测，同时由温度探测器、光电感烟探测器和一氧化碳探测器集为一体的复合式火灾探测器完成火情检测。多传感器的应用实现了低误报率，增强了系统可靠性。自动电话拨号报警是指通过电话网络自动向相关部门发出语音求救信号。当防盗、防火探测器检测到险情的时候，向单片机发出中断申请，再由单片机控制电话接口电路，实现模拟摘机，根据险情类别，自动拨打相关部门的电话号码如小区管理中心电话。本系统通过密码来识别主人身份，系统开启后只有输入正确的密码才能关闭系统。系统从硬件方面进行了抗干扰设计，使其具有较好的抗干扰能力，完成系统可靠工作。关键词：智能报警系统；防盗防火；自动拨号；语音报警AbstractIIAbstractWiththerapiddevelopmentofcommunicationtechniqueandgreatimprovementofstandardofpeople'sliving,theneedofhousehasbeenchangedfromonlythelivingspacetomultiformneedsofquality,function,service,andsoon.Akindofintelligentalarmsystemforresidentialareaisintroduced.Itincludesthefunctionsoftheft-proofandfireproof,performingautomaticdetectionandautomaticdial.PyroelectricinfraredsensorandMicrowavesensorcombinedareusedfortheft-proofsoastorealizeautomaticdetection.Temperaturesensor,PhotoelectricsmokesensorandCOsensorareintegratedtoacompounddetectorforfireproof.Multi-sensorsmaketheleastfalsealarmandenhancethereliabilityofsystem.Automaticdialmeansthatitcansendhelpvoicethroughpublictelephoneswitchnetworktothebureau.Whenthesensoroffireproofingorburglarproofdetectsanyoffnormalsignal,aninterruptrequestissenttotheMCU.NexttheMCUcontroltheinterfacemoduleoftelephonetoaccomplishoffhook.Accordingthekindofdangerous,thedialingmodulewillautomaticallydialtherightphonenumbersuchasthephonenumberofsurveillantcenter.Thesystemdiscernsthemasterbythesecretcode.Onlyimputedcorrectsecretcode,couldsystembeclosed.Thesystemisdesignedbyconsideringtheanti-interferenceinthesideofthehardware.Itcanworkwithhighreliability.KeyWords：intelligentalarmsystem;theft-proofandfireproof;automaticdial;phoneticalarm目录III目录摘要........................................................................................................................IAbstract..........................................................................................................................II1前言...........................................................................................................................11.1序言.................................................................................................................11.2国内外研究概况.............................................................................................11.3我国住宅智能安全防范系统展望..................................................................41.4论文主要工作概述..........................................................................................52系统总体方案设计.................................................................................................62.1智能报警系统的总体构成.............................................................................62.2报警系统的功能及工作过程..........................................................................73用户端探测器设计.................................................................................................83.1防盗探测器电路设计......................................................................................83.1.1热释电红外线探测器............................................................................93.1.2微波探测器..........................................................................................123.2防火探测器电路设计....................................................................................143.2.1温度探测器..........................................................................................163.2.2光电感烟探测器..................................................................................163.2.3CO气体探测器....................................................................................184用户端自动报警器设计.......................................................................................194.1用户端自动报警器总体设计.......................................................................194.2自动报警器电路设计....................................................................................204.2.1AT89C51单片机简介.........................................................................204.2.2自动报警器电路设计..........................................................................224.3串行EEPROM-X25045.................................................................................244.3.1X25045简介........................................................................................244.3.2X25045的工作原理：........................................................................255自动拨号及语音报警电路设计...........................................................................28目录IV5.1拨号电路.......................................................................................................285.1.1拨号电路的主要功能..........................................................................285.1.2MT8888芯片简述...............................................................................285.1.3MT8888外围电路............................................................................325.2语音电路........................................................................................................335.2.1ISD1420芯片简述...........
