Abstract
The present invention provides a wind measurement apparatus based on 3D (three dimensional) non-orthogonal ultrasonic sensor array, the ultrasonic sensor array is composed of two group of ultrasonic sensors, which are centrosymmetrically located at opposite sides, and the angle formed by connecting any two ultrasonic sensors at a side to the symmetry point O is less than 90°, the arrangement of 3D non-orthogonal ultrasonic sensor array reduces the generation of turbulence, thus, the accurate wind speed and wind direction is obtained. In the mean time, the central channel is employed to obtain a reference wind speed v. Comparing the speed component valong central channel of the wind under measurement with the reference wind speed v, if the difference is less than a present threshold, then computing module outputs the measurement results, or discards them, thus the wind measurement accuracy is further improved.
