基于单片机GSM的家居智能防盗控制系统设计

I本科毕业设计(论文)开题报告题目：基于单片机的家居智能防盗控制系统设计院系：控制工程专业：自动化学号：1209101003姓名：崔小雄指导教师：张开生2015年11月西京学院毕业设计II摘要本系统采用嵌入式技术,主要由STC89C51单片机和GSM短信模块组成，借助最可靠、最成熟的GSM移动网络发信息的数据融合与处理,以最直观的中文短消息形式，直接把报警地点的情况反映到您的手机屏幕上。它采用主动式红外传感器进行检测，变有形的传统防盗网防盗窗为无形。GSM短信息模块执行发送短信息给用户手机和接收用户手机的短信息从而建立用户手机和单片机控制系统的远程通信功能。系统主控模块主要完成解释、发送短信息，并实现对各功能子模块的控制。该系统软件采用C语言编制，基本实现了各系统功能。关键词：单片机SIM900A模块传感器嵌入式技术数据融合西京学院毕业设计IIIAbstractTheSystemadoptstechnologyofinlay,ItismadeupofMCUandGSMModem.ItwilldisplaythealarmcontentinChinesedirectlyatyourmobilescreen,anditrecurstothemostreliableGSMmobilenetworkdatacombinationandprocessionofshortmessageofreceptionandsending..Thesystemadoptedinitiativeinfraredsensortodetect,anditturnedthetraditionalalarmnetandalarmwindowstoimmateriality.Besides,thesystemequippedthesmogsensorandleakinesssensorofgasandguardedagainstfireandgasleakiness.WirelessmoduletransitsSMStouser’smobilephoneandreceivesSMSfromuser’smobilephone，soconnectingwithtelecommunicationfunctionbetweenuser’smobilephoneandmicro—controlsystem．Andthecommunicationbetweenthehostcontrolandseveralsubfunctionmodulesisrealizedthroughthepowerlinecarrierwave．ThehostmodulemainlyfulfilsthefunctionofsendingSMSandreceivingSMSandinterpretingSMS，andthencontrollingthesubmodules．Inthepaper,thesystemsoftwareisfinishedusingtheassemblelanguage，andthefunctionofthesystemisrealized．Keywords：MCUSIM900AmodemSensorTechnologyofinlayCombinationofdata西京学院毕业设计IV目录摘要.......................................................................................................................................................II第1章绪论...........................................................................................................................................11.1课题背景..........................................................................................................................................11.2家庭安防的发展与现状..................................................................................................................11.3设计的目的和意义...............................................................................................................................3第2章系统功能及总体设计方案.........................................................................................................42.1系统功能...............................................................................................................................................42.2总体方案设计.......................................................................................................................................4第3章硬件系统设计..............................................................................................................................63.1主控芯片的选择....................................................................................................................................63.1.1STC89C51的功能特性简述..........................................................................................................63.1.2STC89C51最小系统.................................................................................................................73.2GSM无线通讯模块SIM900A.................................................................................................................93.2.1GSMModem的主要功能.............................................................................................................113.2.2GSMModem的硬件电路.............................................................................................................113.3电源电路设计......................................................................................................................................143.3.15V电源设计................................................................................................................................143.3.2传感器选型.................................................................................................................................143.7键盘与显示.........................................................................................................................................153.7.14*4矩阵键盘..............................................................................................................................153.7.2LCD1602.......................................................................................................................................16第4章家庭防盗报警系统的软件设计..................................................................................................184.1主程序流程图......................................................................................................................................184.2外部中断0中断服务子程序流程图.................................................................................................194.3串口通信的软件设置.........................................................................................................................204.4热释电红外HC-SR505的软件设计...................................................................................................214.6液晶显示的软件设计....................................
