Method for judging wrong wiring after meter replacement based on data medium station

The invention belongs to the technical field of electric energy meter detection under big data, and particularly relates to a method for judging wrong wiring after meter replacement based on a data medium station, and the method comprises the steps: obtaining user meter replacement information from the data medium station, and obtaining evaluation index data before and after meter replacement within a preset time range based on the user meter replacement information; calculating the index fluctuation ratio of each evaluation index according to the evaluation index data before and after the meter replacement, comparing each index fluctuation ratio with the corresponding fluctuation threshold, and determining whether the meter wiring of the user is abnormal or not according to the comparison result; if the meter wiring of the user is abnormal, determining a meter wrong wiring estimated value according to the fluctuation rate of each index of the target user and the weight of each evaluation index; and judging w
