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