摘 要
随着无线通信和片上技术的快速发展,远程通信的解决方案也在不断发生着变化。以此为研究背景，主要讨论和设计了一种基于GPRS网络通信的远程数据采集与传输系统的实现方案。选取AD22100温度传感器进行数据采集；利用C8051F020单片机对数据进行控制和处理；同时，单片机通过UART口和内含TCP/IP协议栈的GPRS模块（MC35i）相连，用AT命令实现对GPRS模块的初始化和控制；最后通过GPRS网络和因特网将数据传输至远端的监控中心。这其中主要涉及到了终端硬件设计和传输协议转换等问题。根据GPRS通信技术在中低速率数据传输方面的突出优势，使系统具有一定的高可行性和高性价比。该方案还具有通用性，可用于工业控制、金融、交通等行业，具有很广阔的发展前景。

Title  The Design Of the Remote Data Acquisition And Transmission System
  Based On GPRS Network                                

Abstract
Along with the fast development of wireless communication and the microcontroller technology, the long-distance communication solution is also having the change unceasingly. Take this as the research background，mainly discussed and designed one  realization plan of the remote data acquisition and transmission system based on GPRS network communication .We select the AD22100 temperature sensor to carry on the data acquisition; use the C8051F020 microcontroller to control and process the data ;At the same time, the microcontroller connects with the GPRS module (MC35i) which contains TCP/IP stack through the UART ,and uses the AT orders to realize the initialization and the control of GPRS module; Finally, dates are transferred to the far-end monitoring center through GPRS network and Internet .It mainly involved the design of terminal hardware and the transformation of the transport protocols. For the remarkable advantage of GPRS communication technology applied to middle and low speed rate date transmission, GPRS wireless data acquisition system is of high feasibility and high performance price ratio. The scheme is all-purpose and can be applied to many fields, such as industry control, finance industry and transportation .etc. The design of remote data acquisition system based on GPRS service will be of vast prospect of development.
