【摘要】：房地产热正不断升温,新建住宅小区的配电设备一般安装在地下室的负一、二层,用于用电信息采集的低压集抄集中器、大客户(专变)/公变采集终端都安装在地下室的配电房内,这些设备的上行通信全部采用GPRS/CDMA无线通讯方式,这种通讯方式存在以下问题:大量采集终端安装在地下室无线信号盲区;加装高增益天线成本高昂,施工较复杂,通讯天线的馈线延长后,效果不理想。为消除通讯信号盲区,实现"全采集、全覆盖、全预付费"的系统建设目标,采用宽带电力线载波通信技术开发GPRS网络信号中继器,其可将安装在信号盲区的终端设备的信号通过电力线转接至信号良好的区域,改善采集终端的通讯信号,提高采集终端在线率和远程抄表成功率等。
[Abstract]:The real estate is heating up constantly. The distribution equipment in the new residential district is usually installed on the negative first and second floors of the basement, which is used for the collection of electricity information by the low voltage concentrator. Major customers (special transformer / public transformer collection terminals are installed in the basement of the distribution room, these equipment uplink communication all adopt GPRS/CDMA wireless communication mode, This communication mode has the following problems: a large number of acquisition terminals are installed in the wireless signal blind area of the basement; the high gain antenna is expensive to install and the construction is more complicated; the effect is not satisfactory after the feeder of the communication antenna is extended. In order to eliminate the blind area of communication signal and realize the goal of "full acquisition, full coverage and full prepayment", the GPRS network signal repeater is developed by using broadband power line carrier communication technology. It can transfer the signal of terminal equipment installed in the blind area of signal to the area with good signal through power line, improve the communication signal of collecting terminal, increase the on-line rate of acquisition terminal and the success rate of remote meter reading, etc.
