Abstract

The invention provides a method and a device for fan speed regulation. The method comprises the steps that a network device periodically detects the temperature of the network device, determines the temperature change trend in each period, and determines the number of continuous periods which are matched with the temperature change trend of the period and are adjacent to the period at the end of each period; and if the total number of the continuous periods matched with the temperature change trend exceeds a preset threshold value, the rotating speed of a fan is regulated according to the total temperature change trend of the continuous periods and current rotating speed information of the fan. Through the method, the network device can determine the temperature change trend of the networkdevice when the temperature change of the network device is stable, and the rotating speed of the fan is regulated according to the temperature change trend so that electric energy waste caused by always adjusting the rotating speed of the fan to the maximum can be avoided, and the frequent speed regulation, caused by the network device temperature fluctuation, of the fan can be avoided.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for adjusting the speed of a fan. Background technique [0002] When network equipment is running, a large number of internal components will generate heat. In order to prevent abnormality due to excessive temperature of the device, network devices usually use fans to dissipate heat. A common fan includes multiple gears, and each gear corresponds to a different fan speed, so that the network device can adjust the fan speed by setting the fan gear. [0003] Network devices generally have two ways to adjust the fan speed. [0004] The first way, if the network device is on, always set the fan speed to the maximum. However, the higher the speed of the fan, the more power it consumes, so this method will consume a lot of power and cause unnecessary waste. [0005] In the second method, the network device presets multiple temperature thresh...
