Hardware and software implementation of an embedded metering webserver

Abstract

Our work presents an embedded webserver that can retrofit electronic electricity meters by transforming them into smart meters. The webserver receives data from up to 8 electronic electricity meters on UART and 1 meter on RS-232, then displays the information on a webpage. This device aims to update an Elster A100C electronic electricity meter in order to comply with Automatic Meter Reading requirements and any RS-232 enabled meter with Advanced Metering Infrastructure. The proposed solution is effective from the point of view of the cost and energy consumption.
