The invention relates to an electricity consumption information data processing method, an electricity consumption information acquisition system and an intelligent electric meter, and belongs to the technical field of data distributed computing of electricity consumption information systems. According to the method, the system and the intelligent electric meter, a computing task is decomposed, a simple four arithmetic operation task is screened out, and original centralized computing is changed to distributed computing diverged to the intelligent electric meter, so that part of computing resources of an electricity consumption information acquisition system are released and used for complex computing based on multi-intelligent electric meter data, a large amount of database reading/writing and disk reading/writing during basic computing are reduced, and the computing pressure of the electricity consumption information acquisition system is reduced; and the intelligent electric meter is used for finishing a sent distributed data processing task, so that idle CPU time, network IO and the like of the intelligent electric meter can be used more effectively and the data computing capability of the electricity consumption information acquisition system is improved.
