利用GSM模块SIM100开发短信收发系统利用GSM模块SIM100开发短信收发系统一.引言在开发远程通讯控制系统时，利用现有的GSM网络是一个很不错的选择。这里利用PC串口控制GSMSIM100模块进行收发短消息来实现远程通讯。二.SIM100通讯协议1.COM1或COM2以9600,N,8,1格式通讯2.DTR和RTS须置有效。3.打开监控软件后，须对TE(terminalequipment)初始化。ATCR(0x0d),LF(0x0a) 反馈：xxOKxxATE0CR(0x0d),LF(0x0a) 反馈：xxOKxxATS0=0CR(0x0d),LF(0x0a) 反馈：xxOKxxAT+COPS?(0x0d),LF(0x0a) 反馈：中查到CHINAMOBILEAT+CSCS=GSMCR(0x0d),LF(0x0a) 反馈：xxOKxxAT+CMGF=1CR(0x0d),LF(0x0a) 反馈：xxOKxxAT+CCLK=05/08/23,17：34：59+02CR(0x0d),LF(0x0a) 反馈：xxOKxx4.发送短消息发送：AT+CMGSR(0x0d),LF(0x0a) 反馈中查0X3E(,再发：CNT28SET193022301935224519402255,0X1A,0X0D,0X0A 反馈：xxOKxx5.接收短消息xxxCMTI,SM,Nxxx，并在X的位置查到N，AT+CMGR=NCR(0x0d),LF(0x0a)反馈：+CMGR,SM,1,30,+8613912345678,05/08/03.15:34:32+02MESSAGEOK6.删除短消息AT+CMGD=NCR(0x0d),LF(0x0a) 反馈：xxxxOKxx三.PC上位机例程1.初始化CMainInfoView:OnInitUpdate()m_MSComm.Create(NULL,0,CRect(0,0,0,0),this,78313);m_MSComm.SetCommPort(nCom+1);m_MSComm.SetInBufferSize(2048);m_MSComm.SetOutBufferSize(1024);m_MSComm.SetInputMode(1);m_MSComm.SetSettings(9600,n,8,1;m_MSComm.SetRThreshold(0);m_MSComm.SetSThreshold(0);m_MSComm.SetHandshaking(0);m_MSComm.SetInBufferCount(0);m_MSComm.SetRTSEnable(true);m_MSComm.SetDTREnable(true);pFrame-m_wndStatusBar.SetPaneText(2,strCOM+:没有打开!; if(!m_MSComm.GetPortOpen() m_MSComm.SetPortOpen(true); m_bPortOpen=true;pFrame-m_wndStatusBar.SetPaneText(2,strCOM+:已就绪!;2.读缓冲区长度shortCMainInfoView:GetBufferSize(void)returnm_MSComm.GetInBufferCount(); 3.读缓冲区内容CStringCMainInfoView:GetBufferString(void)VARIANTvariant_inp; COleSafeArraysafearray_inp;LONGlen,k;BYTErxdata2048;variant_inp=m_MSComm.GetInput();safearray_inp=variant_inp;len=safearray_inp.GetOneDimSize();for(k=0;klen;k+)safearray_inp.GetElement(&k,rxdata+k);CStringstrTmp,strRecv;for(k=0;klen;k+)BYTEbt=*(char*)(rxdata+k);strTmp.Format(%c,bt);strRecv+=strTmp;returnstrRecv;4.发送短消息boolCMainInfoView:SendShortMessage(CStringstrNum,CStringstrMsg)inti,j;CStringstrReceive;charch110=0x0d,0x0a,0x00;CStringstrNumCR=CString(ch1);charch210=0x1a,0x0d,0x0a,0x00;CStringstrMsgCR=CString(ch2);CStringstrSend;strSend=AT+CMGS=+strNum+strNumCR;m_MSComm.GetInput();m_MSComm.SetOutput(COleVariant(strSend);Sleep(100);for(i=0;i0)Sleep(100);strReceive=GetBufferString();if(-1!=strReceive.Find()strSend=strMsg+strMsgCR;m_MSComm.GetInput();m_MSComm.SetOutput(COleVariant(strSend);Sleep(500);for(j=0;j=2)Sleep(200);strReceive=GetBufferString();if(-1!=strReceive.Find(OK)/发送短消息成功! returntrue;elsebreak;elsecontinue;/发送短消息失败：没有OKreturnfalse;elsebreak;elsecontinue;/发送短消息失败：没有 returnfalse;5.阅读短消息boolCMainInfoView:ReadShortMessage(CString&strReceived,intnLocation) if(nLocation9)MessageBox(Error:ReadShortMessage:nLocationerror!;returnfalse;CMainFrame*pFrame=(CMainFrame*)AfxGetMainWnd(); charchCMGR20=A,T,+,C,M,G,R,=,0,0x0d,0x0a,0x00; CStringstrTemp; chCMGR8=0+nLocation;CStringstrSend=CString(chCMGR);m_MSComm.GetInput();m_MSComm.SetOutput(COleVariant(strSend); Sleep(400);for(inti=0;i=2)Sleep(500);strReceived=GetBufferString(); if(-1!=strReceived.Find(CMGR&-1!=strReceived.Find(OK/读短消息成功!else/读短消息失败：空信息! returntrue; /读短消息失败:没有回应！ returnfalse;6.删除boolCMainInfoView:eleteShortMessage(intnLocation)if(nLocation9)MessageBox(Error:ReadShortMessage:nLocationerror!;returnfalse; charchCMGD20=A,T,+,C,M,G,D,=,0,0x0d,0x0a,0x00;CStringstrReceive; chCMGD8=0+nLocation;CString strSend=CString(chCMGD);m_MSComm.SetOutput(COleVariant
