Problems solved by technology
[0004] The technical problem to be solved by the present invention is to provide a fan noise control method, device, terminal equipment and storage medium aiming at the above-mentioned defects of the prior art, aiming at solving the problems caused by the high-frequency output of the fan in the prior art when starting. It will lead to a large overshoot of the speed, so the speed changes sharply when the speed is called back, and it is easy to cause noise problems

Embodiment Construction
[0044] In order to make the objectives, technical solutions and effects of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0045] After research, it is found that after the fan is started, in order to quickly reach the preset target speed, it usually outputs high frequency at the beginning of the start to increase the speed. When the fan speed reaches the target speed, the output will be reduced to reduce the speed, so that the fan speed tends to be stable. In the prior art, in order to avoid speed delay, the speed usually drops rapidly after the speed overshoot (that is, the speed is greater than the target speed). Makes rapid changes in speed and is prone to noise. like figure 2 As mentioned in the...

The invention discloses a fan noise control method, device, terminal equipment and storage medium. The method includes: acquiring data of the recalled rotational speed after the fan is started; and determining whether the recalled rotational speed data satisfies noise reduction according to the data of the recalled rotational speed condition; when the recalled rotational speed data satisfies the noise reduction condition, adjust the rotational speed of the fan from the recalled rotational speed data to the preset target rotational speed data, and run at the target rotational speed data. In the present invention, when the recalled rotational speed data satisfies the noise reduction condition, the recalled rotational speed data is used as a rotational speed recall node. Therefore, after the rotational speed of the fan reaches the recalled rotational speed data, the speed is recalled, and the rotational speed of the blower is changed from The speed data is adjusted to the target speed data, and moves with the target speed data, which avoids the fan noise.
Description
technical field [0001] The invention relates to the technical field of fan noise control, in particular to a fan noise control method, device, terminal equipment and storage medium. Background technique [0002] After the fan is started, in order to quickly reach the preset target speed, it usually outputs high frequency at the beginning of the start to increase the speed. When the fan speed reaches the target speed, the output will be reduced to reduce the speed, so that the fan speed tends to be stable. In the prior art, in order to avoid speed delay, the speed usually drops rapidly after the speed overshoot (that is, the speed is greater than the target speed). Makes rapid changes in speed and is prone to noise. [0003] Therefore, the prior art still needs to be improved. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is to provide a method, device, terminal equipment and storage medium for fan noise control in view of ...
