摘要

According to the present invention, in a method of calculating a true wind direction wind speed value by reflecting an error due to inclination of the moving body with respect to a measured value of a wind direction anemometer mounted on a moving body, (a) according to the tilt of the moving body A true wind direction wind speed calculation device including a predetermined electronic compass module installed to be interlocked with the horizontal state of the wind direction anemometer having a horizontal state that changes fluidly, (i) the moving body corresponding to a current point t from the electronic compass module. Gt, which is information about the inclination of,-The Gt is a first XY plane including a Z axis, which is a direction in which gravity acts on the moving object, and a current coordinate corresponding to a predetermined reference point of the moving object perpendicular thereto. Based on the X-axis in the direction and the Y-axis in the second direction, the Zt axis corresponding to the vertical axis of the wind vane at the current point t is θXt, which is an angle rotated from the Z axis in the X axis direction, and the Zt axis The process of obtaining-including θYt, which is an angle rotated from the Z-axis in the Y-axis direction, and (ii) Wmt, which is information on the measured wind measured by the wind vane anemometer at the current point t-the Wmt Is, the measured wind measured by the wind direction anemometer at the current point t is the Xt axis in the third direction and the fourth direction forming the XtYt plane including the current coordinates of the moving body as perpendicular to the Zt axis. Performing a process of obtaining-including measurement values corresponding to each of the Yt axes; And (b) the true wind direction wind speed calculation device performs a first error correction on the Wmt, with reference to the Gt, thereby preventing the correct measurement wind in a space consisting of the X-axis, the Y-axis, and the Z-axis, respectively. Obtaining Wmt', which is information about, and calculating a first true wind direction wind speed value reflecting the inclination of the moving object therefrom; A method comprising a is provided.
