本科毕业论文-基于GPSGSM汽车防盗系统设计.doc

摘要随着中国经济的迅猛发展，人民生活水平的提高，购车的家庭越来越多，私人汽车日益增多，治安状况恶化，汽车被盗对有发生，汽车的定位与防盗也成为市场的一大需求。目前汽车防盗系统存在存在功能简单、可靠性低、误报警、报警距离短等缺点。GPS（GlobalPositioningSystem，全球卫星定位系统）提供了一种可靠有效的车辆定位方法，而利用GSM（globalsystemformobilecommunications，全球移动通信系统）无线通信技术可将定位数据信息迅速传递到接收端，两者结合形成GPS/GSM车辆监控系统，为解决以上问题找到了一个很好的解决办法。如果车主有一部收发短消息的GSM手机，防盗系统就可以实现实时报警，并且GPS可确定具体车辆的方位信息，便于查找丢失的汽车。本文在对目前各种常规汽车防盗装置的不足进行分析的基础上研究一种基于GPS/GSM的智能车辆防盗系统的软硬件设计方案及其实现。该系统由STC12C5A60S2单片机、SIM300无线模块、GPS接收机及防盗传感器等组成。微处理器对收集到的信息进行处理，确认后可锁死发动机同时向车主手机或监控中心发出信息，以实现汽车监控，防止被盗。关键词:GSM；GPS；汽车防盗系统AbstractWiththerapiddevelopmentofChina'seconomy,theimprovementofpeople'slivingstandard,theprincipleofmoreandmorefamilies,privatecarsisgrowingandsecuritysituationisworse,carthefthastohappen,carpositioningandsecurityhasbecomeabigmarketdemand.Atpresentguardagainsttheftsystemissimpleandreliabilityhavefunctionallow,false-negatives,alarmshortdistancefromshortcomings.GPS(globalpositioningsystem)providesareliableandefficientvehiclespositioningmethod,anduseGSM(globalsystemformobilecommunications)wirelesscommunicationtechnologycanwilllocatedatainformationquicklypassedtothereceiver,bothunionformGPS/GSMvehiclemonitoringsystem,tosolvetheaboveproblemfoundagoodsolution.IftheownerhaveamobilephoneshortmessagesandsendandreceivetheGSM,guardagainsttheftsystemcanrealizereal-timealarm,andGPScandeterminetheorientationofthespecificvehicleinformation,itiseasytofindthelostcar.InthispaperatpresentvariousconventionallackofguardagainsttheftsystembasedontheanalysisoftheresearchbasedonGPS/GSMintelligentvehiclesecuritysystemhardwareandsoftwaredesignoftheschemeandrealization.ThesystemconsistsofSTC12C5A60S2microcontroller,SIM300wirelessmodule,GPSreceiverandguardagainsttheftsensoretc.Microprocessortocollecttheinformationprocessing,theenginecanbeconfirmedatthecellphoneownerslockedorthemonitoringcentersendsoutinformation,soastorealizethecarmonitoring,preventthetheft.Keywords:GSM;GPS;Guardagainsttheftsystem目录1前言11.1课题背景11.2课题研究的目的和意义12系统组成及工作原理22.1系统组成22.2单片机控制核心32.2.1STC12C5A60S2系列单片机的内部
