Wind measuring device, wind measuring method, and wind measuring program

Abstract

To provide a wind measuring device that can accurately measure wind speed by eliminating the influence of an obstacle arranged near emitting units that emit ultrasonic waves and receiving units that receive the emitted ultrasonic waves.SOLUTION: A wind measuring device 10 comprises: ultrasonic sensors 11a, 11b, 11c, 11d; a wind microcomputer 18; and a foundation part 15. The ultrasonic sensors 11b, 11d receive ultrasonic waves emitted from the ultrasonic sensors 11a, 11c. A measurement area A1 is surrounded by the ultrasonic sensors 11a, 11b, 11c, 11d. The wind microcomputer 18 measures the wind speed in the measurement area A1 on the basis of a change in the reception timing of the ultrasonic waves. The foundation part 15 is provided near the ultrasonic sensors 11a, 11b, 11c, 11d, and is resistance against the wind directed to the measurement area A1. The wind microcomputer 18 corrects a measurement result by using a correction coefficient that changes according to the direction of the wind so as to eliminate the influence of the foundation part 15 on the measurement of the wind in the measurement area A1.SELECTED DRAWING: Figure 3
