Serial Bus Utilization For Smart Meters In Home Area Network

Abstract

This paper focuses on possibilities of using data from smart meters for home area network applications. Data communication between a smart meter and a consumer for home area network can be done directly witout dedicated communication channel for remote data acquisition. The seriál interface can be used for user data readout, depending on the support of the meters. This paper demonstrates experimental measurements of RS-485 serial bus, with the main objective to find a comparison of different bus configurations and different distances. The main contribution is recommendation of the best RS-485 setup of resistors configuration for home area networks.
