Embodiment 1
[0028] The invention provides a method for correcting the clock of an electric meter based on the average difference, such as figure 1 As shown, the method for correcting the clock of the electric meter includes:
[0029] 11. Network the meter group including the target meter to obtain the meter timing network;
[0030] 12. Regularly extract the meter error value in the meter timing network, and calculate the average difference of all meter error values;
[0031] 13. Obtain the mean value of the factory error of all types of meters in the meter calibration network, and combine the average difference to obtain the calibration mean value;
[0032] 14. Broadcast the calibration mean value in the meter time calibration network, so that the received power meter calibrates its own clock based on the calibration mean value.
[0033] In the implementation, in order to realize the calibration of the clock in the meter, this embodiment proposes a method based on the networking of the ...
