Wind speed and direction sensor and method for kilometer-level marine wind energy unmanned aerial vehicle

Abstract

The invention discloses a wind speed and direction sensor and a method for a kilometer-level marine wind energy unmanned aircraft. During the submersion process with the aircraft, the wind speed and direction sensor is subjected to seawater pressure by a pressure chamber and passed through a sealing ring. Prevent water from entering the sealed chamber, so that the parts inside the sealed chamber are protected; the components outside the sealed chamber of the wind speed and direction sensor are all mechanical parts, and there is no damage when soaked in seawater. During the process of the ocean wind-driven unmanned aerial vehicle coming out of the water and floating on the sea surface, the wind speed and direction sensor measures the wind speed by calculating the frequency of the wind cup driving the pulse gear to cut the light beam of the photoelectric sensing component; by detecting the light beam of the photoelectric sensing component passing through the crack of the gray code disc Angular deflection is generated to perform wind direction measurement.
