Design and Implementation Prepaid Energy Meter Supported by RFID and GSM Technologies

摘要

this paper introduces a modified management system for smart electrical energy meter. The proposed smart meter has feature to inform the consumer about energy consumption, this feature serves energy consumption reduction by self-awareness of real consumption. The other important feature is to eliminating the difficulties by direct contact by employee and consumer to getting the reading of the conventional meter and also reduction of error in bill. The proposal system consists of two parts: client's side part (the prepaid meters in consumer houses) and server side (electrical sub-station). The client part consists of an RFID reader, credit cards, GSM network, Arduino microcontroller and electronic meter. The system operates with high accuracy which could tell the user the amount of energy consumed at any moment and these results the user will be urged to rationalize energy consumption.
