Clock correction method of intelligent electric energy meter and related device

The invention discloses a clock correction method of an intelligent electric energy meter and a related device, and the method comprises the steps: collecting the clock information of the intelligent electric energy meter when an operation and maintenance module is powered on, and carrying out the comparison and correction of the clock information with a clock of the operation and maintenance module, so as to enable the intelligent electric energy meter to be synchronous with the clock of the operation and maintenance module; when the operation and maintenance module receives the broadcast clock of the HPLC module, the broadcast clock and the clock of the operation and maintenance module are compared and analyzed to obtain a correction clock, so that the intelligent electric energy meter is corrected according to the correction clock; when the operation and maintenance module does not receive the broadcast clock within the preset time, state analysis is carried out according to the operation parameters of the
