▲２００２年５月上旬，一种新颖的远程抄表技术－低压载波集中抄表系统项目通过专家验收，并开始在上海市部分居民小区投入使用。由上海市区供电公司开发研制的该系统是运用低压电力线载波技术，将远端采集器所采集的用电信号传输到集中器，实现远程抄表功能。这一技术能提供
▲ In early May 2002, a novel remote meter reading technology - the project of low-voltage carrier concentration meter reading system was accepted by experts and started to be put into use in some residential districts in Shanghai. Developed by the Shanghai Urban Power Supply Company, the system uses low-voltage power line carrier technology to transmit the power signals collected by the remote collector to the concentrator for remote meter reading function. This technique can provide
