2009届本科毕业论文（设计）论文题目：基于GSM的门控及SMS报警系统设计与实现摘要本文详细地叙述了基于西门子公司的TC35i型GSM手机模块的门控及SMS报警系统的软件设计过程。给出了采用TC35i模块和单片机构成的门控控制及SMS报警系统的设计方案，并详细介绍了该系统的软件的工作流程。文章重点阐述了单片机和TC35i模块的通信过程、AT指令的应用、短信PDU编解码在单片机上的实现，程序模块的构成等。该系统单片机通过标准串口经电平变换与TC35i模块相连，完成对TC35i模块的初始化和短消息的数据收发功能，完成单片机与TC35i模块的信息传递，根据传递的信息，去驱动执行机构做出相应的动作。关键词：TC35i模块，SMS报警，AT指令，PDU编解码GatedbasedontheGSMandSMSalarmsystemdesignAbstractThispaperdescribesthesoftwaredesignprocessofalarmsystembasedontheSiemensTC35imoduletypeGSMmobilephoneandSMSgateindetail.Thepapergivesthegatedsingle-chipcontrolandSMSalarmsystemdesignanddetailsofthesystemsoftwareworkflowbyinguseofTC35imodules.Thepaperfocusesondescribingthecorrespondprocessbetweetsingle-chipinterfaceandTC35imodules,TC35ifeaturesandmainfunctions,ATcommandapplication,therealizationofSMSPDUinthesingle-chipcodec,suchasprogrammodules.Thesingle-chipofsystemassociatedwiththeTC35imodulethroughastandardserialporttocompletetheTC35imoduleinitializationandthefunctionofsendingandreceivingshortmessage,tocompletetheimpressionofinformationbetweetsingle-chipandTC35imodule,accordingtothemessage,thesystemdrivetheimplementationtodothecorrespondingaction.Keywords:TC35imodule,SMSalarm,ATcommands,PDUcodec目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc230950177"1引言PAGEREF_Toc230950177\h1HYPERLINK\l"_Toc230950178"1.1课题的背景及意义PAGEREF_Toc230950178\h1HYPERLINK\l"_Toc230950179"1.2课题的应用前景PAGEREF_Toc230950179\h3HYPERLINK\l"_Toc230950180"1.3未来发展方向展望PAGEREF_Toc230950180\h3HYPERLINK\l"_Toc230950181"2方案论证PAGEREF_Toc230950181\h3HYPERLINK\l"_Toc230950182"2.1总体方案选择PAGEREF_Toc230950182\h3HYPERLINK\l"_Toc230950185"2.2无线数据传输模块PAGEREF_Toc230950185\h4HYPERLINK\l"_Toc230950186"2.3GSMModem的选择PAGEREF_Toc230950186\h5HYPERLINK\l"_Toc230950187"3系统总体设计要求PAGEREF_Toc230950187\h8HYPERLINK\l"_Toc230950188"4系统总体设计框图PAGEREF_Toc230950188\h8HYPERLINK\l"_Toc230950190"5端口分配5HYPERLINK\l"_Toc230950191"6软
