摘要随着科学技术的不断更新和发展，工业生产等各个领域对信息数据的传输有了更高的要求。单单依靠于有线的数据传输方式，已经不能满足目前各种通信应用的需求。这时，GPRS终端通信技术的产生与应用，令远程数据传输的发展得到很大的提升。以GPRS业务为基础的无线通信技术已成为当代通信的研究热点。86068

本课题的研究目的是以GPRS网络为基础，利用模块的收发短信功能，来建立一个实现信息传递和发布的系统。将GPRS模块和单片机系统共同作为此信息发布系统的控制器，通过GPRS网络作为数据的传输通道，来实现LCD显示系统的信息发布功能。本系统设计的主要通信方式是基于短消息的无线数据传输，即经过模块收发短信来实现信息的无线发送。

在系统的设计过程中，通过构建系统的总体结构，来确定硬件器材的型号选择，与各功能模块的软件程序设计。本系统利用STC单片机系统、GPRS模块、液晶显示屏等器件，以及计算机终端和各种软件应用，来实现短信控制、远程数据传输等功能。在软件设计中，将软件部分设计进行分模块设计，给出了整个系统程序设计的总体流程图，阐述了在短消息业务下的整体通信系统设计，在Keil4编译环境下实现工程文件的创建、编辑与烧入。最后，对系统的主要功能进行调试，验证是否达到系统设计的要求。

Abstract With the continuous renewal and development of science and technology, industrial production and other fields have a higher requirement for data transmission。 It already can not meet the current needs of a variety of communication applications only on the wired data transmission mode。 At this time, the production and application of GPRS terminal communication technology make the development of the remote data transmission be greatly improved。 Service of wireless communication technology based on GPRS has become a hot topic of contemporary communication。

The purpose of this research is to establish a system of information transmission and distribution based on the GPRS network and the function of the module。 Through the GPRS network as the data transmission channel, the GPRS module and SCM system are common as the controllers of this information release system to achieve the information release function of the LCD display system。 The main communication mode of the system is based on the short message of the wireless data transmission, that is, by way of sending and receiving text messages to achieve the wireless transmission of information。

In the design process of the system, according to the general structure of the building system, the model selection of hardware equipment and software program designs of each functional module are determined。 This system makes use of STC single-chip microcomputer system, GPRS module, liquid crystal display and other devices, as well as computer terminals and a variety of software applications to implement the message control, remote data transmission and other functions。 In software design, software design is pided into several modules。 The system shows the flow chart of the overall program design, and introduces the whole communication system design in short message service。 It is to realize engineering files to create, edit, and burn-in in the Keil4 compiler environment。 Finally, the main function of the system is debugged, in order to verify whether it can meet the requirements of system design。
