The invention provides an electricity utilization information acquisition system electric energy meter protocol standard conversion method, and relates to the field of electric power system electricity utilization information acquisition. The acquisition system master station requires conversion of two protocols to establish business data connection with the electric energy meter at present, whichlacks equipment interoperability and great extensibility. The concentrator and the electric energy meter are connected through an object-oriented acquisition device, and the electric energy meter andthe acquisition device use the protocol standard of "DL/T 645"; and the acquisition device and the concentrator and the concentrator and the acquisition system master station use the protocol standard of "object-oriented interoperability data exchange agreement". The acquisition system master station requires conversion of the two protocols to establish business data connection with the electricenergy meter, and the two communication protocol standards have equipment interoperability and great extensibility. According to the technical scheme, the interoperability, the compatibility and the extensibility between all the equipment in the acquisition system can be greatly enhanced.
