Embodiment Construction

[0039] In order to understand the characteristics and technical content of the present invention in more detail, the implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the present invention.

[0040] In the related art, in order to transfer the heat generated by the electronic equipment to the air in time, it is necessary to control the rotational speed of the fan. For example, the rotation speed of the fan of the electronic device may be controlled by using the rotation speed adjustment curve of the fan in combination with the current ambient temperature of the electronic device. Here, taking the electronic device as an example, based on an open loop control (open loop) method, the air inlet temperature of the fan of the server is used as the control variable, and the fan speed is used as the controlled variable to es...

Abstract

The embodiment of the invention discloses a control method and device and a storage medium, and the method comprises the steps: obtaining the current rotating speed of a fan of electronic equipment and the current environment temperature; determining a first corresponding relation based on the current rotating speed and the current environment temperature; wherein the first corresponding relationis related to the altitude of the current position of the electronic equipment; and adjusting the rotating speed of the fan by utilizing the first corresponding relation and combining the current environment temperature, so that the fan can meet the heat dissipation requirement of the electronic equipment at the altitude.

Description

technical field [0001] The present invention relates to the field of fan control, in particular to a control method, device and storage medium. Background technique [0002] At present, electronic equipment generates heat during operation. Usually, the heat generated by the electronic equipment can be transferred to the air through a fan installed on the electronic equipment. In practical applications, in order to transfer heat generated by electronic devices to the air in a timely manner, it is necessary to control the speed of the fan. For example, the current ambient temperature of the electronic device may be used to control the rotational speed of the fan of the electronic device. [0003] In the above method, the rotational speed of the fan is controlled according to the current ambient temperature, and the altitude of the fan at the current location of the electronic device may not be able to meet the cooling requirements of the electronic device.
