Method for identifying wiring state of electric energy metering device

The invention provides a method for identifying the wiring state of an electric energy metering device, and the method comprises the steps: obtaining equipment parameters of a target electric energy metering device, judging whether current daily electric quantity data is empty or not when the target electric energy metering device is identified as a single-phase meter, judging whether the maximum current value of the target electric energy metering device is greater than a preset first current threshold value or not; judging whether the minimum current value is smaller than or equal to a preset second current threshold value and whether the number of times smaller than 0 is larger than or equal to a preset number-of-times threshold value; when the minimum current value is smaller than or equal to a preset second current threshold value and the number of times smaller than 0 is larger than or equal to a preset number-of-times threshold value, whether the daily line loss amounts of multiple consecutive days in
