Remote embedded power measurement system based on global network

Abstract

A remote embedded power measuring and supervising system is developed based on the global network. The electric signal such as voltage, current and power for a single-phase two-wire circuit or a three-phase three-wire circuit can be measured by the power measurement device. The center embedded server composed of the embedded Linux OS (Operation System) called as TimeSys [1] and embedded framework with Hitachi microcomputer [2], works as the bridge between users and power measurement devices. RS485 communication bus is designed to connect at most 31 measurement devices to the center server. The web access service based on the network communication interface is provided to enable remote data supervising, comparing, downloading, and so on. The whole system achieves remote supervision and abundant data analysis for energy conversation. © 2007 IEEE.
