基于GSM的库房安全报警系统——软件设计.doc

摘要本文详细地叙述了基于西门子公司的TC35i型GSM手机模块的无线库房报警系统的设计过程。文中探讨了利用GSM短消息作为数据传输媒介实现远程监视和控制库房的可行性，给出了采用TC35i模块和AT89S52单片机构成的能够远程监视和控制库房的无线报警系统的设计方案，给出了系统的硬件组成并着重介绍了软件的工作流程。文章重点阐述了AT89S52单片机和TC35i模块的接口、TC35i的特点和主要功能、AT指令的应用、短信PDU编解码在单片机上的实现，无线热释电红外探测器和无线门磁的工作原理等。关键词：GSM模块；RS232串口；单片机；AT命令；无线探测器BasedonGSMsecurityalarmsystemforthedesignoftheTreasury--SoftwareDesignAbstractThisarticledescribesindetailbasedontheSiemensTC35imoduletypeGSMmobilephonewirelesswarehousealarmsystemdesignprocess.ThearticlediscussestheuseofGSMshortmessageasadatatransmissionmediumtoachieveremotemonitoringandcontrolofthefeasibilityoftheTreasury,TC35igiventheuseofsingle-chipmodulesandAT89S52posedtoremotelymonitorandcontrolthetreasuryofthewirelessalarmsystemdesign,Giventhecompositionofthesystem'shardwareandsoftwarefocusedonworkflow.AT89S52articlefocusesonsingle-chipinterfaceandTC35imodules,TC35ifeaturesandmainfunctions,ATcommandapplication,SMSPDUcodecontherealizationofthesingle-chip,wirelesspyroelectricinfrareddetectorsandthewirelessdoor-magnetismsuchastheworkingprinciple.Keywords：GSMmodule；RS232serialport；Single-chip；ATcommand；Wirelessdetectors目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc231222616"1绪论PAGEREF_Toc231222616\h1HYPERLINK\l"_Toc231222617"2方案论证PAGEREF_Toc231222617\h1HYPERLINK\l"_Toc231222618"2.1控制器部分设计方案PAGEREF_Toc231222618\h1HYPERLINK\l"_Toc231222619"2.2GSM模块的选择PAGEREF_Toc231222619\h2HYPERLINK\l"_Toc231222620"3系统结构框图PAGEREF_Toc231222620\h3HYPERLINK\l"_Toc231222622"3.1MCU中央控制部分PAGEREF_Toc231222622\h3HYPERLINK\l"_Toc231222623"3.2LED指示电路部分PAGEREF_Toc231222623\h4HYPERLINK\l"_Toc231222624"3.3无线报警信号接收及解码电路PAGEREF_Toc231222624\h4HYPERLINK\l"_Toc231222625"3.4GSM模块接口部分PAGEREF_Toc231222625\h4HYPERLINK\l"_Toc231222626"3.5报警输出控制部分PAGEREF_Toc231222626\h4HYPERLINK\l"_Toc231222627"3.6系统供电部分PAGEREF_Toc231222627\h4HYPERLINK\l"_Toc231222628"4系统软件设计PAGEREF_Toc231222628\h5HYPERLINK\l"_Toc231222629"4.1GSM常用AT指令PAGEREF_Toc231222629\h5HYPERLINK\l"_T
