Embodiment Construction

[0080] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0081] Fans are usually used for heat dissipation of electronic equipment, and the air volume of the fan is a factor that directly affects the heat dissipation effect. The fan includes the fan and the fan blades. The fan rotates according to the control signal, and then drives the fan blades to rotate, thereby generating wind. The fan's speed dire...

Abstract

The embodiment of the invention provides a fan, a fan controller, electronic equipment and a fan identification method. The fan identification method comprises the following steps: receiving an identification request message sent from the fan controller; and sending fan information to the fan controller to cause the fan controller to identify the fan according to the fan information. The fan, the fan controller, the electronic equipment and the fan identification method, which are provided by the embodiment of the invention, are used for automatically identifying the fan.

Description

technical field [0001] The embodiments of the present invention relate to automatic control technology, and in particular to a fan, a fan controller, electronic equipment, and a fan identification method. Background technique [0002] With the improvement of the performance of electronic equipment, the integration level is getting higher and higher, and the power consumption is also increasing. The problem of heat dissipation in the equipment has become particularly prominent. There are many ways to solve the heat dissipation problem of the equipment, among which the use of fans for forced air cooling is an effective means. [0003] At present, the most widely used fan is a pulse-width modulation (PWM) fan. The PWM fan can control the rotational speed through the PWM signal to achieve the effect of energy saving and noise reduction. However, since there are many types of fans, the control signals for controlling different PWM fans are also different. If a dedicated fan cont...
