电能计量远程集中抄表系统的建设与应用

基于GPRS等远程无线自动抄表系统在技术争议中不断发展，取得了长足的进步，正在大面积地推广使用。低压电力线载波自动抄表系统采用扩频、跳频、正交频分复用、阻抗适配滤波、转发中继（载波表可以动态地被本地集中器通过电力线设置为路由器或转发器）等技术及专用芯片，不断克服我国电网拓扑复杂、污染严重带来的诸多实际问题，其抄表成功率大为提高。

Electric energy remote concentrated meter reading system construction and Application

GPRS based remote wireless automatic meter reading system in technical disputes in constant development, has made considerable progress, is a large area to promote the use of. Low voltage power line carrier automatic meter reading system based on spread .spectrum, frequency hopping, OFDM, adaptive filtering, impedance relay （ carrier sheet can dynamically be local concentrator via power line is set to a router or tran- sponder） technology and special chip, and constantly to overcome our country power network topology complex, serious pollution brings many actu- al problems, the meter reading success rate is greatly improved.
