基于GPRS网络的配变监控终端TTU的设计

The Study of Transformer Terminal Unit(TTU) Based on GPRS Network

本文阐述了配变监控(TTU)在配电网中的作用及其功能,介绍了一种基于ARM处理器实现利用GSM网络的GPRS网络通信技术来进行远程数据采集和传输控制、以及数据图像的处理。该系统由于GPRS的永远在线、按量收费等优点与ARM和单片机的控制计算强大功能相结合保证了整个系统能稳定、经济运行。

The paper describes the functions of TrU（Transformer Terminal Unit） for electricity-distributing net, and introduces a Terminal Unit based on the technique of GPRS network that makes the transmission of the remote data,control information and data of images become possible. The GPRS that has the advantages such as always on-line,charging on quantity and so on and the combination of ARM and SCM prove the system running steadily and economically.
