电能表无线射频集抄系统的研究及前景分析

Study and Prospect Analysis of Radio Frequency Centralized Reading System for Watt-hour Meters

介绍了远程自动抄表系统及其3种技术方案:RS-485集抄系统、电力载波集抄系统和无线射频(radio frequency,RF)集抄系统,分析了前两种系统分别存在的问题,认为RF集抄系统可作为前两种集抄系统的有效补充,适用于电能表安装比较分散和铺设线路不方便的小区。详细介绍了RF集抄系统在国内外研究、使用的现状及其优缺点,并对其在设计、应用、推广及试验检测等方面存在的相关问题进行了说明。

The long-distance automatic meter reading（AMR） system is described along with its three technical schemes： RS- 485 centralized reading system, power carrier centralized reading system and radio frequency（RF） centralized reading system. The problems of the first two systems are analyzed, it is held that RF centralized reading system could be an effective supplement to the first two systems, applicable to communities featured by distributed installation of watt-hour meters and inconvenience in laying cables. The research and use actualities of the RF system at home and abroad are introduced in detail besides its merits and faults. Relevant issues in its design, application, promotion and test, etc. are also explained.
