Abstract

The present application provides a method and a device for adjusting the speed of a fan. In this application, the network device periodically detects its own temperature, and determines the temperature change trend in each cycle, and at the end of each cycle, determines the temperature of the continuous cycle that matches the temperature change trend of this cycle and is adjacent to this cycle. number. If the total number of consecutive cycles matching the temperature change trend exceeds the preset threshold, the fan speed is adjusted according to the total temperature change trend of the continuous cycle and the current fan speed information. Therefore, the network device can determine the change trend of the device temperature when the temperature change of the device is stable, and adjust the fan speed according to the temperature change trend, which can not only avoid the waste of power caused by always adjusting the fan speed to the highest, but also avoid the temperature change caused by the device temperature. Frequent fan speed adjustments caused by fluctuations.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and device for fan speed regulation. Background technique [0002] When network equipment is running, a large number of internal components heat up. In order to prevent abnormal device temperature from occurring, network devices usually use fans to dissipate heat. A common fan includes multiple gears, and each gear corresponds to a different fan speed, so the network device can adjust the fan speed by setting the fan gear. [0003] Network equipment generally has 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 fan speed, the more power is consumed, so this method consumes a lot of power and causes unnecessary waste. [0005] In the second method, the network device presets multiple temperature thresholds to determine multiple temperature int...
