摘要
本文旨在利用GPRS实现无线传输数据。首先介绍基于通用分组无线业务(GPRS)的无线数据传输技术,然后对应用单片机C51实现GPRS模块串口通信进行研究,给出硬件设计原理图,并且给出程序设计流程图。对基于C51的GPS和GPRS模块进行了仿真,提出用GPRS技术进行无线数据传输的实现方法。实践证明,利用GPRS传输数据与传统的数据传输方式相比,具有耗资小、体积小、分布广、使用灵活等优点。
The research aim of this paper is through GPRS to realize wireless data transmission. This thesis firstly recom-mends the wireless data transmission technology based on GPRS. Then the research is done to implement the serial communi-cation on the GPRS module which combined with the use of the singlechip C51. Its hardware principle chart is given, and the software flow figures are provided. After that,it is necessary to simulate on the GPS/GPRS module combined with C51 and to realize the wireless data transmission based on GPRS technology. Testified by the practice,the method of GPRS is more cheap, little,wide and smart than traditional data transmission.
