摘要
针对用户电能表的抄表由传统人工方式转变为综合应用电子技术、数字通信技术及计算机网络技术的远程自动抄表系统方式的现状,介绍了电能表远程抄表系统的基本构成。重点分析了几种电能表远程抄表系统的组成结构、工作原理及主要优缺点,并对其进行了应用比较。总结得出,GPRS远程抄表系统正逐步成为电能表远程抄表应用的主流。
Aiming at the status that meter reading had been transformed from traditional manual mode to automatic remote meter reading system mode, which comprehensively applied electronic technology, digital communication technology and computer network technology, the basic components of remote electrical energy meter reading system were introduced. The composition of structure, working principle and relative merits and dismerits of several remote electrical energy meter reading systems were analyzed, as well as made some application comparisons among them. It was concluded that GPRS remote meter reading system was becoming the main tendency of remote electrical energy meter reading application.
