Description: 目前的智能机在硬件上多采用双cpu的架构，一个是基带处理器，主要处理数字信号、语音信号的编码解码以及GSM通信协议，另一个是应用处理器，运行操作系统和各种应用程序。基带处理器、射频和其它外围芯片作为一个模块，成为GSM/GPRS modem，提供AT命令接口。网络的应用已经是一个需求的热点，而目前的GSM模块大多都能支持GPRS功能。应用处理器通过AT命令集与带GPRS功能的无线通讯模块通信，为实现网络的应用提供了一个最底层的支持。
-Intelligent machines in the current hardware on many dual-cpu architecture of a baseband processor are mainly deal with digital signals, voice signals, and GSM codecs communication protocol, and the other is the application processor, operating system and applications running procedures. Baseband processor, radio frequency and other peripheral chips, as a module, as a GSM/GPRS modem, provided by AT command interface. Application of network needs is a hot spot, and most of the current GSM module can support GPRS function. Application processor through the AT command set and functionality with GPRS wireless communication module, in order to achieve the application of the network provides a bottom support. Platform: |

Description: 本文通过对现代远程通信方式的讨论，提出了利用现有GSM网络的短消息业务实现的远程通信的种种优势，并将这种方式应用于本设计系统。采用先进的GSM通信模块和单片机互连的终端系统，通过AT指令，实现了数据的发送。在PC机端，通过VB编程实现人机友好交互界面，通过连接GSM模块实现接收终端发出的数据的功能。文中论述了GSM系统的组成结构、主要业务，重点介绍了短消息业务的特点、结构等方面，并基于此建立了整个系统。详细介绍了系统主要硬件组成部分及其作用，给出了整个系统软件流程图和部分子程序流程图。介绍了该技术的应用前景和推广价值。而且提出了本系统尚需解决的一些问题，并给出了可能解决这些问题的途径和方法。但是由于利用短消息业务存在时延等问题，本文基于此还提出了另一种基于GPRS的系统方案。介绍了GPRS的业务特点，网络结构等方面，并给出了整个系统设计.-Based on the modern long-distance means of communication to discuss the proposed use of the existing GSM network Short Message Service to achieve the various advantages of long-distance communications, and in this way the system used in this design. The use of advanced single-chip GSM communication module and the interconnection of the terminal system, through the AT command, the realization of the data sent. In the PC-side, through the VB program to achieve a friendly man-machine interface, through the GSM module to connect terminals to receive data sent. In this paper, the structure of GSM system, the main business focuses on the characteristics of SMS, structure, and based on the establishment of the whole system. Details of the hardware components of the system and its role, given the entire system software flowchart flow chart and some subroutines. Introduced the technology and promote the value of prospects. But the system still need to be put forward to solve some of the problem Platform: |
