Filtering method and filtering control device of weighing sensor

The invention provides a filtering method and a filtering control device of a weighing sensor, and the filtering method comprises the steps: carrying out the filtering of first weighing data obtained by the weighing sensor through employing a plurality of filtering units, and obtaining a plurality of second weighing data, wherein the plurality of filtering units have different building times; obtaining a fluctuation index of each piece of second weighing data, and establishing a corresponding relation between the fluctuation index of each filtering unit and the establishment time; a target filtering unit is determined according to the weighing requirement in the corresponding relation, the fluctuation index of the target filtering unit is matched with the target precision in the weighing requirement, and the establishment time of the target filtering unit is matched with the target speed in the weighing requirement. According to the filtering method and the filtering control device provided by the invention,
