[0001] The present invention relates to the field of smart meters, and in particular, to a smart meter data recognition device. Background Art

[0002] A smart meter is one of the basic devices for data collection in a smart grid (especially a smart distribution network), undertaking the tasks of collecting, measuring, and transmitting original electrical energy data, and is the basis for realizing information integration, analysis optimization, and information display. In addition to the basic power consumption measurement function of a traditional electricity meter, in order to adapt to the smart grid and the use of new energy, a smart meter also has intelligent functions such as two-way multi-rate metering function, user-side control function, two-way data communication function with multiple data transmission modes, and anti-stealing electricity function.

[0003] However, due to manufacturing process deviations, it is difficult for each of the same type of smart meters produced on a smart meter production line to meet the expected size requirements.
