Currently, the demand of precise and lean energy consumption service for residents is growing constantly. Aiming at this situation, according to the principles of IR 46 (International Recommendation 46), an electricity meter for load identification based on multi-core modularity is designed to improve the level of detailed electric data analysis. With metering module, general function module and load analysis module embedded separately, the intelligent identification analysis for type, turn-on/off time and electricity consumption of household appliances is realized in triple cores management mode by load data acquisition, feature extraction, load identification, and record results upload. Meanwhile, a remote update scheme relying on electricity information acquisition system is proposed to ensure online update for load identification algorithm and load sign database.
