Device and method for detecting obstruction degree of dustproof mesh, and electronic equipment thereof

Abstract

An embodiment of the invention provides a dust-proof net plugging degree detection device, a method and an electronic equipment, adaptable to different environments to detect the plugging degree of the dust-proof net. The device comprises a wind speed detection unit, a data conversion module and a plugging detection unit; the method comprises the following steps: collecting the rotating speed of a fan, and the wind speed parameters at the rotating speed; obtaining the wind resistance characteristic parameters, according to the rotating speed of the fan and the wind speed parameters at the rotating speed; and determining the plugging degree of the dust-proof net based on the wind resistance characteristic parameters and the alarm threshold value. The device in the embodiment of the invention can adapt to various environments and different dust-proof nets, which can give an alarm directly based on the dust-proof net plugging degree determined by the wind speed so as to notify the user to timely clean or replace the dust-proof net.

Description

technical field [0001] The invention relates to a detection technology, in particular to a device and method for detecting the clogging degree of a dust-proof net, and electronic equipment. Background technique [0002] At present, most of the heat dissipation of electronic equipment is realized by air cooling, and the performance of the air cooling system is very important for the stable operation of the equipment. In order to effectively dissipate heat and reduce the corrosion of electronic equipment caused by accumulated dust, most air-cooled heat dissipation systems will be equipped with dust filters, especially for electronic equipment that requires high reliability. The dust accumulation state of the dust-proof net will directly affect the air-cooling performance of the electronic equipment. The dust accumulation of the dust-proof net will reduce the heat exchange efficiency of the electronic equipment and affect the safe and stable operation of the electronic equipmen...

AI Technical Summary

Problems solved by technology

Using the deformation detection method requires high sensitivity of the detection switch, which is easily affected by the outside world and leads to false detection

In addition, because this solution is not suitable for the dust-proof net with high strength and small area and the dust-proof net with reinforced grid, etc., its scope of application is limited.
