Abstract
In order to solve the problem that the existing volunteer ship true wind measurement is not accurate enough, this paper studies the ship motion compensation technology and the ship true wind measurement method, and proposes a ship true wind measurement technology based on RT-Thread. A measurement system is built with STM32 single chip microcomputer as the main control core, RT-Thread operating system as the basis, supplemented by various acquisition sensors, The hardware and software of the measurement system are introduced in detail. Combined with the five indexes of wind direction, wind speed, bow direction, speed and heading, the compensation of ship motion is realized, the influence of ship rolling, pitch and other motions is eliminated, and the true wind value is obtained to help users master the true wind data of the ship in time.
