Capacitance adjusting method, device, equipment and medium

Abstract

The invention provides a capacitance adjusting method and device, equipment and a medium, and the method comprises the steps: determining a preset variable quantity of an adjusting unit according to a current capacitance value and a target capacitance value of an adjustable capacitor, and controlling the adjusting unit to change the preset variable quantity in a first adjustment direction, so as to adjust the capacitance value of the adjustable capacitor; when the adjusting unit stops adjusting the capacitance value of the adjustable capacitor, the accumulated variable quantity of the adjusting unit within the time from the time when the adjusting unit starts adjusting the adjustable capacitor to the time when the adjusting unit stops adjusting the adjustable capacitor is obtained, and the calibration variable quantity is determined according to the accumulated variable quantity when adjusting is stopped and the preset variable quantity; and according to the relationship between the calibration variable quantity and the first threshold value, the adjustment unit is controlled again by the calibration variable quantity to adjust the capacitance value of the adjustable capacitor in the first adjustment direction, or the adjustment of the capacitance value of the adjustable capacitor is stopped, or the adjustment unit is controlled to adjust the capacitance value of the adjustable capacitor in the second adjustment direction. According to the invention, the adjustable capacitor can be adjusted to obtain a required capacitance value.
