Problems solved by technology
[0007] The main purpose of the present invention is to provide a fan control system and its control method to solve the problem that the existing fan system continuously generates a large amount of noise, which causes inconvenience to users, and the method of reducing the fan speed when the noise is to be reduced or stopped is likely to cause safety problems. Concerns about the problem, as well as shortcomings such as the user must establish rules to control the fan and may input improper control parameters to the fan system

The invention discloses a fan control system which comprises fans, power source conversion devices, a control device and a human-machine interface. Each power source conversion device is connected with the corresponding fan, the control device is connected with the power source conversion devices and comprises a storage module which is provided with a first database, first control data are stored in the first database, the human-machine interface is connected with the control device and is provided with a graphical interface, and second control data are set through the graphical interface of the human-machine interface and stored in the first database of the storage module to enable the control device to automatically control the fans to run at first rotating speed in a first time period and run at second rotating speed in a second time period according to the first control data and the second control data.
Description
technical field [0001] The present invention relates to a fan control system, in particular to a fan control system and its control method integrating hardware and software interfaces and methods. Background technique [0002] With the development of science and technology, various fan systems, such as small wind power generation systems, have been widely used in ordinary households to obtain energy through wind power generation. [0003] Generally speaking, the speed of a small wind power generation system changes with the external wind speed. The ratio of the speed to the wind speed is determined by the matching of the generator torque of the wind turbine and the fan blades. Therefore, the speed of wind turbines of different designs will be different. When the external wind speed increases, the speed of the fan increases accordingly, accompanied by wind shear noise from fan blades and low-frequency vibration noise from towers on the structure, etc., which often affect the ...
