基于STM32的智能安防系统的设计学生专业：电子信息科学与技术学生姓名：王正辉指导教师：康辉I摘要随着社会的发展，人们的生活质量越来越高，家用电器和厨房设施也随之增多,家庭存在的安全隐患相应增加,同时整个社会正处于转型期，家庭的安全问题也引起了人们的关注。传统的安全防范措施已无法适应现代化社会的需求。因此，将智能化引入住宅小区已成为一种趋势，并且在智能化住宅的家庭智能管理系统中，安防报警已经成为民用建筑领域，向信息化和网络化发展的一个重要组成部分。基于将最新的通信技术融合到传统产业中的考虑，本文综合了单片机、无线数据通信、数据采集等技术，研究并设计了以STM32单片机基于GSM短信模块作为信息传输的家庭安防系统。此系统由主控制器、显示模块、信息传输模块和防盗模块，防火模块，声光报警模块等组成，可解决传统安防系统存在的隐患，让家庭防盗更及时、使用更方便。它不再依赖有线电话执行报警，而是借助最可靠、最成熟的GSM移动网络，以最直观的中文短消息形式，直接把报警情况反映到用户的手机屏幕上，并发出声音报警，可以防范一定的险情，用户可以通过无线遥控对该系统进行布防和解防。该系统具有用户投资小，运营费用少的优点，并且操作简单。关键词安防系统；防火；STM32；GSMIIAbstractWiththedevelopmentofthesociety,ThequalityofpeoplelifebecomemoreAndmoregood，Accordingly,ThenumberofhouseholdelectricalappliancesAndkitchenfacilitiesalsobecomemore，Sothesafehiddentroubleinsecurityfamilyisincreasing,atthesametimethewholesocietyisintransitionperiod,thefamilysecurityproblemhascausedtheattentionofpeople.Traditionalsecuritymeasureshavebeenunabletomeettheneedsofmodernsociety.Therefore,ithasbecomeatrendtotheintroductionoftheintelligentresidentialdistrict,AndSecurityalarmhasbecomeanimportantpartofthefieldandcivilconstruction,theinformationAndnetworkdevelopment.Inconsiderationofbasedonthelatestcommunicationstechnologyintegratedintotraditionalindustries,thisarticlecombinationtheknowledgeofthemicro-controller,wirelessdatacommunication,dataacquisitiontechnology.Thenresearchanddesignthehomesecuritysystem，basedonGSMmoduleastheinformationtransmissionandSTM32micro-controller.Thissystemconsistsofmaincontroller,displaymodule,informationtransmissionmoduleandalarmmodule,fireprotectionmodule,soundalarmmodule.Thesecuritysystemcansolvethehiddendangerexistedinthetraditionalsecuritysystem，makethefamilysecuritymorequickly,moreconveniently．Itisnolongerdependonthecabletelephone,butwiththehelpofthemostreliableandmostmatureGSMmobilenetwork,usethemostintuitiveformofChinesemessage,thealarmsituationreflectstotheuser．Thissystemcanpreventsomedangeroussituations;userscancontrolthesystemforprotectionorreconciliationbythewirelessremote.Thesystemhasadvantagesthattheuserhasasmallcostandoperatingexpenses.KeywordsSecuritysystem；Fireprevention；STM32；GSMIII目录摘要..........................................................................................................................IAbstract..................................................................................................................II第1章绪论...........................................................................................................11.1课题背景和意义..........................................................................................11.2国内发展现状..............................................................................................11.3智能安防系统的发展前景..........................................................................3第2章系统方案设计...........................................................................................42.1设计任务与要求..........................................................................................42.2方案的比较..................................................................................................42.3系统总体设计思路......................................................................................62.4本章小结......................................................................................................7第3章系统硬件设计...........................................................................................83.1主控模块的设计..........................................................................................83.1.1STM32最小系统...................................................................................83.1.2SD卡电路的设计................................................................................103.1.3字库Flash接口电路..........................................................................113.2防火监控的设计........................................................................................113.2.1烟雾传感器的电路设计.....................................................................123.2.2天然气体浓度监测的电路设计.........................................................123.2.3电流传感器的工作原理和电路设计.................................................133.2.4火焰传感器的电路设计.....................................................................143.3防盗监控的设计........................................................................................153.4环境监控模块............................................................................................163.4.1温湿度传感器的电路设计.................................................................163.4.2CO传感器的工作原理和电路设计....................................................173.5报警模块的设计........................................................................................183.5.1声音报警.............................................................................................183.5.2GSM模块短信报警............................................................................19IV3.6人机交互显示模块的设计........................................................................223.7电源模块...................................................................
