毕业设计题目：GSM手机短信火灾报警器学院：电气与信息工程学院专业：电气工程及其自动化姓名：学号：指导老师：完成时间：年月日摘要火灾是一种终极型灾害，大多数灾害最后都可能导致火灾。火灾能给人类社会带来巨大的损失。然而，旧时的火灾报警器已经不能满足现代人的要求，有线的火灾报警器具有一定的局限性，经常出现线路故障等问题，而无线火灾报警器能打破局域限制，减少因线路故障引起的不便。同时GSM手机短信火灾报警器，双向通信更能在第一时间满足设计要求，同时实现远程无人控制，做到安全，经济的最优化。系统采用AT89S52,该芯片具有高速、低耗能、功能强、价格低、寿命长，适合运行较为复杂的算法；采用MQ-2烟雾传感器经ADC0832模数转化芯片同时配合DS18B20温度传感器作为探测器，报警系统将传感器输出的电信号送入AT89S52中，得到的数字信号由单片机系统进行处理分析，判断火灾是否发生。当检测信号为火灾发生时，由GSM模块发出火灾给用户手机，检测终端进行声光报警。系统的结构简单，性能稳定，使用方便，智能化程度高。由于采用了温度传感器和烟雾传感器相结合的探测方法，比使用单一的探测器能更加准确报警，降低了误报率。关键词：烟雾传感器MQ-2；GSM模块；DS18B20温度传感器AbstractFireisakindofultimatedisaster,mostdisasterslastmayresultinafire.Firecanbringhugelosstohumansociety.Oldfirealarm,however,havealreadycan'tmeettherequirementsofmodernpeople,cablefirealarmhassomelimitations,oftenappeartheproblemsuchaslinefault,andwirelessfirealarmsystemcanbreakthelocallimit,reducetheinconveniencecausedbythefailuresoftheline.GSMSMSfirealarmatthesametime,thetwo-waycommunicationcanmeetthedesignrequirementsinthefirsttime,atthesametimefortheremotecontrol,security,theoptimizationoftheeconomy.SystemUSESAT89S52,thechiphasahighspeed,lowenergy,strongfunction,lowprice,longservicelife,suitableforrunningmorecomplexalgorithms;WithMQ-2smokesensorADC0832modulusconversionchipwithDS18B20temperaturesensorasthedetectoratthesametime,thealarmsystemwillbethesensoroutputsignaltotheAT89S52andprocessingofdigitalsignalbysinglechipmicrocomputersystemanalysis,todeterminewhetherafirehappened.Whenthesignalisthefire,madebytheGSMmoduletotheusermobilephone,firedetectionterminalforsoundandlightalarm.Systemstructureissimple,stableperformance,easytouse,intelligentizedegreeishigh.Withthecombinationoftemperaturesensorandsmokesensorsdetectmethod,probecanbemoreaccuratethanusingasinglealarm,reducestherateoffalsepositives.Keywords:smokesensorMQ-2;TheGSMmodule;DS18B20temperaturesensor目录摘要..................................................................................................................................IAbstract.............................................................................................................................II1绪论.............................................................................................................................11.1GSM手机短信火灾报警器概述.......................................................................11.2国内外火灾报警器发展及现状........................................................................11.2.1国内无线火灾报警系统的发展现状.....................................................21.2.2国外火灾报警器发展与现状.................................................................21.3未来无线火灾报警系统发展趋势....................................................................31.4课题研究的目的与意义....................................................................................32GSM手机短信火灾报警器的总体...
