摘要
重点介绍了在用电信息采集设备安装过程中,遇到公网GSM信号不够稳定或信号较弱、缺失等上行通信信道GPRS或SMS的信号质量问题,以及通过有源或无源信号放大装置和技术手段解决这些问题,实现公网GSM信号的增强和信号稳定,使用电信息采集终端通讯速率和稳定性得到提高,以达到提高用电信息采集设备远程采集相关数据的目的。
This article focuses on the several GPRS or SMS signal quality problems in the installation process of electricity infomlation collection devices, such as the public network is not stable enough GSM signal, or the signal is weak or missing, as well as solves these problems through active or passive signal amplification device and technical means, realizes the public network GSM signal enhancement and signal stability, improves the electrical intbrmation collection terminal communication rate and the stability, in order to achieve the purpose of the power infomation acquisition device collecting relevant data in the long distance.
