step S310, determining whether the first check code is the same as the second check code.
In this embodiment, according to the first check code obtained in step S100 and the second check code obtained in step S200, whether the first check code and the second check code are the same is compared inside the smart meter.
And step S320, judging that the smart electric meter is successfully verified.
