For example, if the maximum rotation speed of the fan is 5000 revolutions, the minimum unit of the duty ratio of the fan to be controlled is 1%, and the maximum unit is 100%, the rotation speed of the corresponding fan to be controlled is 0-5000 revolutions, and when the current duty ratio of the fan to be controlled is adjusted, the corresponding rotation speed of the fan is increased or decreased by 50 revolutions every time the current duty ratio of 1% is increased or decreased, and the rotation speed of the fan is controlled by adjusting the current duty ratio of the fan to be controlled.

In one embodiment, the fan speed control method further includes:
and judging whether other fans to be controlled need to be adjusted, and if so, adjusting the current duty ratios of the other fans to be controlled according to the current rotating speeds of the other fans to be controlled.
Specifically, after the rotating speed of the fan to be controlled is adjusted, whether other fans to be controlled need to be adjusted is judged, and the judging method also judges whether the current rotating speeds of the other fans to be controlled meet a preset rotating speed range or not and judges whether the current duty ratios of the other fans to be controlled meet a maximum adjustable duty ratio range or not. If other fans to be controlled need to adjust the current rotating speed, the current duty ratios of the other fans to be controlled are adjusted according to the current rotating speeds of the other fans to be controlled, and the adjusting method is also used for adjusting the current duty ratios of the other fans to be controlled by operating a pulse width modulation method so as to adjust the rotating speeds of the other fans to be controlled. And when the rotating speeds of all the fans to be controlled are adjusted, ending the control flow.
In this embodiment, after the adjustment of the fan to be controlled is completed, whether other fans to be controlled need to be adjusted is determined, and if the other fans to be controlled need to be adjusted, the current duty ratios of the other fans to be controlled are adjusted according to the current rotating speeds of the other fans to be controlled, so that the rotating speed adjustment of the multiple fans is realized, and the adjustment precision of the fan to be controlled is improved.

If the current rotating speed of the fan to be controlled does not meet the preset rotating speed range, judging whether the current duty ratio of the fan to be controlled meets the maximum adjustable duty ratio range: if the current rotating speed of the fan to be controlled does not meet the preset rotating speed range and the current duty ratio of the fan to be controlled does not meet the maximum adjustable duty ratio range, not adjusting the current rotating speed of the fan to be controlled; and if the current rotating speed of the fan to be controlled does not meet the preset rotating speed range and the current duty ratio of the fan to be controlled meets the maximum adjustable duty ratio range, adjusting the current duty ratio according to the current rotating speed. When the fan to be controlled is adjusted, if the current rotating speed of the fan to be controlled is greater than the preset current gear rotating speed, the current duty ratio of the fan to be controlled is reduced; and if the current rotating speed of the fan to be controlled is less than the preset current gear rotating speed, increasing the current duty ratio of the fan to be controlled. And after the fan to be controlled is adjusted, judging whether other fans to be controlled need to be adjusted, if so, adjusting the current duty ratios of the other fans to be controlled according to the current rotating speeds of the other fans to be controlled, and if not, ending the whole control flow.
