Problems solved by technology

[0004] However, the above existing technologies are applicable to five-wire fans, while the industry’s common application interfaces for four-wire fans, PWM, FG, and steering control bus can only choose two out of three, and cannot be compatible with all functions, so they cannot be used in live network products. Smooth upgrade, compatible with both positive and negative air ducts without changing the fan design

Abstract

The embodiment of the invention discloses a fan control method, device and system, which are used to realize the speed regulation and steering control of a four-wire forward and reverse fan interfaced with a conventional four-wire fan through a PWM control bus. The method in the embodiment of the present invention includes: receiving the first fan regulation signal sent by the system control module, converting the first fan regulation signal into a forward steering control signal according to the duty ratio interval of the first fan regulation signal and the current steering direction of the fan, Reversing the steering control signal or switching the steering control signal, and sending the converted control signal to the fan drive module, so that the fan drive module drives the fan to run according to the converted control signal.

Description

technical field [0001] The present invention relates to the field of communication technology and computer technology, and in particular, to a fan control method, device and system. Background technique [0002] In communication equipment and information technology (IT, Information Technology) equipment systems, fans are usually used to assist in cooling the equipment. With the increase of network traffic, the power consumption of communication equipment is increasing, and the performance of the fan is required to be stronger. The rotation speed of the fan reaches tens of thousands of revolutions. In order to prevent dust from being sucked into the equipment and affecting the life of the fan, the fan is required to be reversed, so as to realize the automatic dust removal function; The temperature difference between day and night varies greatly, which will also affect the life of the fan and indirectly affect the reliability of the equipment. Therefore, in this system, the ...
