Abstract

A fan detector comprises fan circuits of a plurality of fans, a vibrator circuit, a controller circuit and a state indicator circuit. The vibrator circuit comprises vibrators as many as the fans; each vibrator is used for sensing corresponding fan states; each vibrator is further used for outputting a vibration signal. The controller circuit is used for receiving the vibration signals output by the vibrators; the controller circuit judges whether or not the corresponding fans fully stop according to the vibration signals; when the corresponding fans fully stop, the controller circuit outputs a low-level vibration signal; when the low-level vibration signal output by a controller chip is received, indicative information about stopping of the fans is output. The fan detector is capable of indicating whether or not the fans fully stop rotating; changing the fans is facilitated for users.

Description

technical field [0001] The invention relates to a fan detection device. Background technique [0002] In current server designs, hundreds of fans are used to cool each server. However, when there is an error in these fans that needs to be replaced or taken off, since the fan to be replaced or taken off may not have completely stopped rotating, if it is forcibly taken off at this time, it may affect the operation. cause a certain risk of injury. Contents of the invention [0003] In view of the above, it is necessary to provide a fan detection device that can indicate the rotation status of the fan. [0004] A fan detection device, comprising: [0005] a fan circuit including at least one fan; [0006] A vibrator circuit, including vibrators corresponding to the number of these fans, each vibrator is used to sense the operating state of a fan, and each vibrator is also used to output a vibration signal corresponding to the sensed fan; [0007] A controller circuit, inc...
