Abstract

The invention applies to the field of communication devices, and discloses a fan control system, a system management device and fans. The fan control system comprises the system management device, one or more fan interfaces and one or more fans, wherein the system management device is connected with one fan through one fan interface and comprises a system controller; each fan comprises a drive circuit, which is used for driving a motor, and a fan controller. Therefore, the system controller can send a specification selection command to the fan controller according to the heat dissipation requirements of different communication devices so as to switch to a matched fan specification; under the fan specification, the system controller sends a speed regulation command to the fan controller to further control the fan rotating speeds, so as to realize accurate control. According to the invention, the heat dissipation requirements of different communication devices are effectively satisfied; the fan rotating speed can be further regulated according to work environments at different temperatures; the practicability is high; humanization is achieved.

Description

technical field [0001] The invention belongs to the field of communication equipment, and in particular relates to a fan control system, a system manager and a fan. Background technique [0002] Communication networks have penetrated into daily life and work, and have become an indispensable existence. The communication network is mainly composed of communication equipment such as mobile communication equipment and Internet communication equipment, so as to realize data transmission between communication equipment and realize business functions such as telephone and web browsing. [0003] With the increase of communication traffic, the load of communication equipment increases, and it is often necessary to use fans to dissipate heat inside the communication equipment. Due to the different power consumption of different communication devices, the amount of heat required to be dissipated is also different, so the fan specifications selected are also different; thus, matching ...
