基于多路GSM通道的JAVA短信群发系统的设计与实现

-I-基于多路GSM通道的JAVA短信群发系统的设计与实现摘要:本文使用Java串口通信技术和JSP技术，并应用于Windows平台下的Web系统中，在对GSM移动通讯系统的短信息(SMS)业务通信中AT指令的介绍，以及短信格式、编码与解码等分析的基础上，介绍了一种使用GSM短信传送任意格式文件的方法，将文件压缩并分割封装成适合短信传送的数据包，通过GSM短信发送给接收方，接收方接收之后将数据包还原、解压得到原始文件，从而实现了通过GSM网络在两台计算机之间传送文件.在办公自动化领域，基于短信平台的办公自动化有助于提高办公效率。针对现有管理信息系统信息发布缺乏实时性的缺点，笔者提出了建立基于GSMModem的短信辅助办公系统的信息发布平台，即构建一个移动短信信息发布平台，为办公自动化系统提供短信功能支持，从而提高办公效率和节约办公成本。平台设计的目标是通过网络在平台上发布信息并同时用短信的功能及时通知员工。把GSMModem与计算机终端连接进来，实现串口通信，通过GSMModem向指定用户手机发送短信消息，实现移动办公，提高办公信息化水平。关键词：串口通信；GSM移动通讯；AT指令-II-ThedesignandimlentationofJAVASMSbasedonmultipleGSMchannelsAbstract：ThisarticleusestheJavaserialcommunicationtechnologyandJSPtechnology,andappliedtothewebsystemfortheWindowsplatform,theintroductionoftheATcommandintheGSMsystemformobilecommunicationsshortmessage(SMS)businesscommunications,andmessageformat,encodinganddecodinganalysisonthebasisofaGSMSMSsendanyfileformat,filecompressionandsplitthepackageintoapacketfortextmessagessentviaGSMtextmessagessenttotherecipient,therecipientreceivesthepacketrestoresolutionpressuretogettheoriginalfile,inordertoachievethroughtheGSMnetworktotransferfilesbetweentwocomputersinthefieldofofficeautomation,officeautomationbasedontheSMSplatformtohelpimproveofficeefficiency.Releasedtothelackofreal-timeshortcomingsofexistingmanagementinformationsystem,theauthorproposestheestablishmentofinformationpublishingplatformbasedonGSMModemSMS-officesystem,thatistobuildamobilemessaginginformationreleaseplatform,SMSfunctionsupportforofficeautomationsystem,whichtoimproveofficeefficiencyandtoreducethecostofoffice.TheplatformdesigngoalistopromptlynotifytheemployeesthroughtheinformationnetworkontheplatformandatthesametimeusetheSMSfunction.GSMModemandcomputerterminalsconnectedcometorealizetheserialcommunicationtothedesignatedmobilephoneuserstosendSMSmessagesviaGSMModem,mobileoffice,toimprovethelevelofofficeinformation.Keywords：Serialcommunication;GSMmobilecommunications;ATcommands-III-目录1.绪论.............................................................................................................................................11.1移动通讯的应用背景..................................................................................................11.2GSM模块简介..................................................................................................................21.3GSM发展前景..................................................................................................................31.4本论文的设计思想........................................................................................................42.基于多路GSM通道的JAVA短信群发系统的设计.........................................................62.1系统功能需求...............................................................................................................62.2系统整体框架的设计..................................................................................................72.3数据库结构的设计......................................................................................................82.4AT指令简介和和短信发送介绍...............................................................................82.4.1短信透明发送...................................................................................................82.4.2W5360模块短信接收.....................................................................................162.4.3其他AT指令...................................................................................................113.系统实现..................................................................................................................................123.1收发短信......................................................................................................................123.2定时功能的实现.........................................................................................................144.系统的测试和运行结果......................................................................................................164.1登录界面......................................................................................................................164.2管理员密码设置界面................................................................................................164.3发短信主界面.............................................................................................................164.4发短信成功后界面....................................................................................................174.5常用短语界面.............................................................................................................175.总结...........................................................................................................................................18[参考文献]..................................................................................................................................19附录...........................................................................................................................................20致谢...........................................................................................
