1. A radio frequency interference processing method, the method comprising:

  • the method comprises the steps that when a terminal carries out communication and charging, the downlink communication frequency of the terminal is obtained, wherein the downlink communication frequency currently used by the terminal belongs to a low-frequency band;

    acquiring the working frequency of a charging adapter connected with the terminal, wherein the charging adapter comprises a frequency conversion device;

    determining higher harmonic frequencies of preset orders of the working frequency, wherein the numerical value of the preset order is less than 50, and calculating the frequency interval between each higher harmonic frequency and the downlink communication frequency;

    determining the frequency interval with the minimum value as a target frequency interval, and judging whether the target frequency interval is smaller than a preset interval threshold value;

    if the target frequency interval is smaller than a preset interval threshold value, determining that the harmonic wave of the working frequency has interference with the downlink communication frequency;

    if the target frequency interval is judged to be larger than or equal to a preset interval threshold value, determining that no interference exists between the harmonic wave of the working frequency and the downlink communication frequency;

    and if the working frequency and the downlink communication frequency are interfered, sending a frequency conversion instruction to the charging adapter, wherein the frequency conversion instruction carries a preset variation value so as to reduce the interference of the working frequency of the charging adapter on the downlink communication frequency, and the frequency conversion instruction is used for indicating the charging adapter to use the frequency conversion device to reduce or improve the working frequency according to the preset variation value.
