Abstract

The invention discloses a reversible wind driven generator with a display function and a control method of the reversible wind driven generator. Information such as characters, pictures and animations can be displayed through wind energy, a motor is switched to a motor mode when the rotating speed of fan blades is too small so that stable display can be achieved, and high application value is achieved. The content needing to be displayed is subjected to modulus taking, data obtained after modulus taking are transmitted to a controller in a wireless transmission mode, LEDs installed on the fan blades of the wind driven generator are controlled to display the content, and when the fan blades of the wind driven generator rotate and reach a certain speed, the LEDs installed on the fan blades can display complete information such as images or animations in the air. The motor is set to be in two working modes according to the current rotating speed of the fan blades: (1) a generator mode; and (2) a motor mode. According to the display control method, display parameters are jointly adjusted through rotating speed feedback control and position feedback control, and the LED display brightness is adjusted through external environment light intensity information so that stable and effective display can be achieved.

Description

technical field [0001] The invention belongs to the technical field of LED light display, and in particular relates to a system and a control method for realizing rotating LED display on a fan blade of a wind power generator by utilizing the persistence of vision effect. Background technique [0002] When the object is moving fast, when the image seen by the human eye disappears, the human eye can still retain the image for about 0.1 to 0.4 seconds. This phenomenon is called the persistence of vision (POV) phenomenon. have a property. At present, the phenomenon of persistence of vision is widely used in the field of LED lighting display, and has been widely used. This design combines the POV display technology with the wind turbine. Due to the uncertain and unstable speed of the wind turbine, the final display effect will be greatly affected. These problems still need to be solved. Contents of the invention [0003] The purpose of the embodiments of the present invention...
