Gateway meter with relatively high utilization rate and evaluation method

The invention discloses a gateway meter with a high utilization rate and an evaluation method, and the method comprises the steps: collecting the electric energy of a terminal, carrying out the statistics of the electric energy through an electric energy metering device, and obtaining an electric energy value; classifying and verifying the superior gateway meter and the subordinate electric energy meter, and after verification is completed, performing electric energy collection to obtain an output electric energy value of the superior gateway meter and an input electric energy value of the subordinate electric energy meter; and the main controller is adopted to correct the output electric energy value and the input electric energy value, if a processing result meets an output requirement, the processing result is directly exported, and otherwise, the processing result is corrected until the output requirement is met. The upper-level gateway meter is matched with the lower-level electric energy meter, so that
