摘要：The measurement of wind speed and wind direction is an important part for marine meteorological big data, which provides support for national key marine laboratory. Aiming at the measurement error, which is caused by the relative motion of the ship, and improving its measurement accuracy, this paper proposes a true wind measurement method based on mobile sensor. Since the movable sensor measures the relative wind, we use the electronic compass module and the GPS module to measure the direction and speed of the ship's motion respectively. Calculate the wind speed and direction of the true wind through vector synthesis. In order to overcome the influence of ship sway and other factors, we add a gyroscope and use the fourth-order Runge-Kutta method to solve the quaternion differential equation to obtain the attitude angle of the ship. On this basis, the extended Kalman filter algorithm is used to fuse the collected data and attitude angle. The results show that under the condition of different wind speeds, the error value of wind speed is stable below 0.6m/s, and the error value of wind direction is below 0.5°. The accuracy of real wind speed is improved well.
