In an optional example, in a case that the time difference is greater than or equal to a preset threshold, the target electric energy meter is controlled to enter a programming state, and after the calibration operation is performed on the date information and the clock information of the target electric energy meter in the programming state, the method further includes: controlling a preset motor to rotate to release a programming key of the target electric energy meter; and under the condition that the programming key is released, the control target electric energy meter exits the programming state.
According to the method, after the date and time of the electric energy meter are calibrated, the motor of the clock management module is controlled, the motor drives the pressing rod when rotating, the programming key of the electric energy meter is pressed down through the pressing rod, the programming state is exited, and other misoperation in the programming state is prevented.
In an optional example, in a case that the time difference is greater than or equal to a preset threshold, the target electric energy meter is controlled to enter a programming state, and after the calibration operation is performed on the date information and the clock information of the target electric energy meter in the programming state, the method further includes: and recording and storing the date information and the clock information of the calibrated target electric energy meter.
