【摘要】：房地產(chǎn)熱正不斷升溫,新建住宅小區(qū)的配電設(shè)備一般安裝在地下室的負(fù)一、二層,用于用電信息采集的低壓集抄集中器、大客戶(專變)/公變采集終端都安裝在地下室的配電房?jī)?nèi),這些設(shè)備的上行通信全部采用GPRS/CDMA無(wú)線通訊方式,這種通訊方式存在以下問(wèn)題:大量采集終端安裝在地下室無(wú)線信號(hào)盲區(qū);加裝高增益天線成本高昂,施工較復(fù)雜,通訊天線的饋線延長(zhǎng)后,效果不理想。為消除通訊信號(hào)盲區(qū),實(shí)現(xiàn)"全采集、全覆蓋、全預(yù)付費(fèi)"的系統(tǒng)建設(shè)目標(biāo),采用寬帶電力線載波通信技術(shù)開(kāi)發(fā)GPRS網(wǎng)絡(luò)信號(hào)中繼器,其可將安裝在信號(hào)盲區(qū)的終端設(shè)備的信號(hào)通過(guò)電力線轉(zhuǎn)接至信號(hào)良好的區(qū)域,改善采集終端的通訊信號(hào),提高采集終端在線率和遠(yuǎn)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.
