Description

Technical Field

[0001] The present invention relates to the technical field of solar fans, and particularly to a dynamic wind speed regulation control system for solar fans. Background Art

[0002] A solar fan is a device that uses solar energy as the main energy source. It converts solar energy into electrical energy through a solar panel, and then the electrical energy drives a motor to drive the fan blades to rotate, thereby achieving ventilation and cooling. It combines modern photovoltaic technology and the functions of traditional fans, aiming to provide an energy-saving and environmentally friendly ventilation solution. Solar fans operate independently without the need to connect to an external power source, are easy to install, and have high flexibility. They are particularly suitable for temporarily erected places or mobile devices, such as tents, RVs, fishing boats, etc. In some emergency situations, such as the rescue site after natural disasters, solar fans can be quickly deployed to provide necessary ventilation and cooling functions. In the long run, the use cost of solar fans is relatively low. Although the initial investment may be relatively high, since there is no need to pay electricity bills during operation and the maintenance cost is low, they have a high cost performance. In some commercial applications, such as agricultural greenhouses, farms, etc., solar fans can help reduce energy consumption costs and improve production efficiency. With the continuous progress of photovoltaic technology and the continuous reduction of costs, the application prospect of solar fans will be broader. Future solar fans may integrate more efficient solar panels, more advanced energy storage technologies, and more intelligent control systems to further improve performance and user experience. At the same time, with the continuous enhancement of people's environmental awareness, solar fans are expected to be more widely applied and promoted globally.

[0003] Existing solar fans generally change the wind speed by adjusting the angle of the fan blades. The solar fan is designed with an adjustable fan blade angle mechanism, and users can manually adjust the angle of the fan blades according to their needs to control the magnitude of the wind speed. In some high-end solar fans, there may also be equipped with remote control devices such as a remote controller or a smartphone APP. Users can conveniently adjust the wind speed and other parameters of the fan through these devices. However, with these adjustment methods, users will adjust according to their current feelings, and there is a certain degree of cumbersome inconvenience in operation. Summary of the Invention

[0009] The wind speed evaluation module calculates a comprehensive environmental index ZHhj, a historical average wind speed FSls, and a reference average wind speed FScz based on the collected data sets, calculates an optimal wind speed index ZJfs based on the calculation results, calculates a wind speed regulation difference TJcz based on the optimal wind speed index ZJfs, and determines whether wind speed regulation is required based on the wind speed regulation difference TJcz. In the case where wind speed regulation is required, it sends the regulation difference TJcz to the power evaluation module.

[0010] The power evaluation module calculates the current power supply amount DLgj based on the regulation difference TJcz, and determines whether the power supply and demand are sufficient based on the power supply amount DLgj.
