摘要：本文提出了利用现有GSM(Global System of Mobile Communication)网络的短消息业务实现远程通信的种种优势，并将这种方式应用于远程检测系统。整个系统以GSM网络作为远程信号的传输平台，对数据进行远程传输，数据的传输方式主要采用短消息方式和PDU编码模式。文中对GSM系统的组成和结构进行了详细的介绍，分析了基于GSM网络的数据传输方式的原理和一些基本特性，并对GSM的主要AT指令和PDU编码方式进行了研究。在此基础上，对TC35i模块和MSP430F149单片机及其外围电路设计进行了论述，进而完成了数据传输的硬件部分电路设计；并且运用IAR公司为MSP430系列单片机开发的C430集成开发环境和C语言调试器作为程序开发工具，实现数据的远程无线传输，给出了整个系统的软件流程图和部分子程序流程图。最后提出了系统尚需解决的一些问题，并给出了一些可能解决这些问题的方法。

Study in Wireless Communication System of GSM SMS
Abstract：This paper presents variety advantages in long-distance communication by using short message service of GSM (Global System of Mobile Communication) network and applies this technique in remote monitoring system. In this system, GSM network is a medium for transmitting data whose mode is most SMS (Short Message Service) and PDU mode. First, the paper presents the constitution and structure of GSM, and analyses the principle of data transmitting mode based on GSM network. It presents the main AT command and PDU mode. In this paper, TC35i, microchip MSP430F149 MCU and peripheral circuit are introduced, and then the design of transmission circuit board is completed. Using C-language debugger and C430 integration developing environment that IAR designed for MSP430 single chip, the long-distance data communication is accomplished, and both the main program and the transmitting subprogram flow sheets are provided also. At last, some problems which are need to solve and corresponding suggestion are presented.
