Description

Technical Field

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

[0002] Solar fans are devices that use solar energy as the main energy source, convert solar energy into electrical energy through solar panels, and then use electrical energy to drive the motor to drive the fan blades to rotate, thereby achieving ventilation and cooling. It combines modern photovoltaic technology with the functions of traditional fans to provide an energy-saving and environmentally friendly ventilation solution. Solar fans operate independently, do not need to be connected to an external power supply, are easy to install, and have high flexibility. They are particularly suitable for temporary sites or mobile devices, such as tents, RVs, fishing boats, etc. In some emergency situations, such as rescue sites after natural disasters, solar fans can be quickly deployed to provide necessary ventilation and cooling functions. In the long run, the cost of using solar fans is low. Although the initial investment may be high, it has a high cost-effectiveness because it does not need to pay electricity bills during operation and has low maintenance costs. In some commercial applications, such as agricultural greenhouses and farms, solar fans can help reduce energy consumption costs and improve production efficiency. With the continuous advancement of photovoltaic technology and the continuous reduction of costs, the application prospects of solar fans will be broader. In the future, solar fans may integrate more efficient panels, more advanced energy storage technologies, and more intelligent control systems to further improve performance and user experience. At the same time, as people's awareness of environmental protection continues to increase, solar fans are expected to be more widely used and promoted around the world.

[0003] Existing solar fans generally change the wind speed by adjusting the angle of the fan blades. Solar fans are designed with an adjustable fan blade angle mechanism. Users can manually adjust the angle of the fan blades as needed to control the wind speed. Some high-end solar fans may also be equipped with remote control devices such as remote controls or smartphone apps. Users can use these devices to easily adjust the fan's wind speed and other parameters. However, these adjustment methods are all adjusted by users based on their current feelings, and there is a certain degree of cumbersomeness and inconvenience in operation. Summary of the invention

[0045] By analyzing the data set composed of multiple historical current fan wind speed data in the current area and the data set composed of multiple other fan wind speed data in the same area, it is easy to understand the historical wind speed data in the current area and the reference data of other fans, so as to achieve a comprehensive and multi-angle analysis of the most suitable wind speed. At the same time, through multiple data sets, data errors can be reduced and data quality can be improved;

[0046] The wind speed assessment module calculates the comprehensive environmental index ZHhj, the historical average wind speed FSls, and the average wind speed FScz according to the collected data set, and calculates the optimal wind speed index ZJfs according to the calculation result. The wind speed assessment module calculates the wind speed adjustment difference TJcz according to the optimal wind speed index ZJfs, and determines whether wind speed adjustment is required according to the wind speed adjustment difference TJcz.

[0062] The power evaluation module calculates the current power supply DLgj according to the adjustment difference TJcz, and determines whether the power supply and demand are sufficient according to the power supply DLgj. If the power supply is sufficient, it sends a wind speed adjustment signal to the wind speed adjustment module, and if the power supply is insufficient, it sends a power shortage signal to the feedback module.
