Abstract

The fan control device comprises a controller mainboard, a switching power supply and a detection load, the positive electrode of the switching power supply is used for being connected with the positive electrode of a fan, the negative electrode of the switching power supply is used for being connected with the negative electrode of the fan, and the negative electrode of the switching power supply is connected with the ground of the controller mainboard; the negative electrode of the switching power supply and the first end of the detection load are used for connecting detection voltage, the second end of the detection load is connected with the ground of the controller mainboard, and the first end of the detection load serves as a detection port. Whether the fan cathode is grounded or not can be detected according to level signals of the detection port, implementation is easy and convenient, detection efficiency is high, in addition, when the fan cathode and the switching power supply cathode are successfully connected with the controller mainboard ground, electromagnetic compatibility of the fan can be improved, output air volume of the fan is stable, working performance of the fan is improved, and the service life of the fan is prolonged. And the use reliability of the fan is improved.

Description

technical field [0001] The present application relates to the technical field of fluid machinery, in particular to a fan control device and fan equipment. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas conveying machinery. Generally speaking, fans include ventilators, blowers, wind generators, etc. The air conditioner fan is a commonly used fan, which can transport gases of different temperatures to the target area and play a role in temperature regulation. [0003] Traditional fans are used under the control of a controller. The controller sends the control signal to the fan through the control signal line, and the fan adjusts its working state according to the control signal. However, at present, the control and wiring requirements of various fans are different, and it is often the ...
