基于GSM网络远程家庭智能监控系统

摘要随着GSN网络的迅速普及移动通信技术的飞速发展，新技术和新业务的开发和应用已提到十分重要的位置。将GSM技术运用于实现家庭智能报警具有实际应用价值。该系统以单片机AT89S52为核心作为控制模块，由GSM无线通信模块、传感器数据信息采集模块、液晶显示模块和报警模块组成。通过传感器模块中光电传感器和温度传感器采集相关信号，经A/D转换模块转换成单片机可处理的数字信号，经过语音报警模块发出相关报警信号，将该信号通过GSM短信模块，借助GSM移动网络，以中文短消息，直接把报警地点的情况反映到您的手机屏幕上。该系统具有安全保密性高，又不需要组建专用网络和维护网络，网络覆盖面广，因此与传统的监控系统相比有着其独特的优势。关键词：智能监控;AT89S52单片机；GSM网络；传感器；报警系统；ABSTRACTWiththerapidpopularizationofGSMnetworksandthefastdevelopmentofmobilecommunicationtechnology,newtechnologiesandserviceshavebeensteppeduptoanall-importantposition.GSMtechnologywillbeappliedtoachievepracticalapplicationofintelligentalarmhomevalue.ThesystemisMCUAT89S52thecoreasacontrolmodule,whichisconsistoftheGSMwirelesscommunicationmodule,sensordataacquisitionmodule,LCDmoduleandalarmmodule.Photoelectricsensormodulethroughthesensorandtemperaturesensoracquisition-relatedsignals，throughtheA/Dconvertermoduleintodigitalsignalswhichasinglechipcanhandle,afterissuingtherelevantalarmvoicealarmmodulesignals，thesignalisthroughtheGSMSMSmodule，withGSMmobilenetwork,throughChineseshortmessage,directlytothealarmlocationisreflectedtoyourmobilephonescreen.Thetheoryisverysimpleandhashighsecurity,andthereisnoneedtosetupspecialnetworksandtomaintainthem,moreovertheareaofGSMnetworkscoveringisverywide,sothismethodhasmanyparticularadvantagesoverconventionalmonitoringsystem.KeyWords：Intelligentmonitoring;AT89S52singlechipmicrocomputer;GSMnetworks；Sensor；Alarmsystem1................................................................................................................................引言12............................................................................................................方案选择及论证32.1................................方案1——基于8031单片机的防盗报警监控系统设计53.1.......................核心控制单元AT89S52模块——闪电存储型器件AT89S5263.1.1AT89S52单片机概述...........................................................................63.1.2AT89S52单片机特性...........................................................................73.1.3AT89S52引脚功能与封装...................................................................83.2.........................................................................GSM无线通信模块——TC35i103.2.1AT指令说明.......................................................................................123.2.2PDU编码规则....................................................................................133.2.3单片机与TC35i的软件接口及控制原理.........................................133.2.4RS-232串行接口................................................................................143.3.................................................................................传感器数据信息采集模块173.3.1温度传感器.........................................................................................183.3.2光电传感器.........................................................................................223.4.....................................................................................................液晶显示模块243.4.1方案1——采用LED液晶显示屏....................................................243.4.2方案2——采用点阵式数码管显示.................................................243.4.3方案3——采用1602液晶显示器...................................................2432.2...........................方案2——基于GSM网络的远程家庭智能监控系统设计43....................................................................................................系统硬件电路的设计第3/81页3.5.............................................................................................................报警模块263.5.1蜂鸣器的介绍.....................................................................................273.5.2蜂鸣器方案选择.................................................................................274............................................................................................................系统程序的设计294.1.....................................................................................................主程序流程图335.1.............................................................................................................硬件测试335.1.1静态调试............................................................................................335.1.2联机调试............................................................................................335.2.............................................................................................................软件测试35结论......................................................................................................................36参考文献......................................................................................................................37附录一：电路原理图..................................................................................................38附录二：控制源程序..................................................................................................39致谢......................................................................................................................73345.3.............................................................................................................系统调试346...
