摘　　要：在电力配网自动化、负荷管理、远程抄表及调度自动化系统中,有一些应用区域存在GPRS信号未覆盖或者GPRS信号不良的情况,部分孤点无法通信,导致数据传输失败,严重影响电力系统生产与管理。本文设计一种解决GPRS信号不良区域数据通信问题的通信装置,使用230MHz电力专网进行通信,达到GPRS信号延长的目的。。In power distribution network automation , power load management , remote meter reahingand power dispatehing automation system. , there are some areas have no GPRS signal or flaky mobile-network coverage. Informationis lands resulting in communication failure , which seriously affected the production and management of electric power system. A communication device which improve data transmission of the poor signals in many areas was developed. The 230 MHz wireless channel of electric power private network was used , which extended the range of data transmission.
