一种新型手持式测风装置

A New Hand-Held Measuring Device

介绍了一种手持式测风装置,其内部三轴加速度传感器用来测量船舶的横摇及纵摇摆信息,并通过相关算法来修正测量的风速风向值,利用内部GPS模块中航速、航向信息与测量的合成风通过矢量运算得出真风速、真风向,气压模块与电子罗盘模块可以给用户提供不同的参数信息,为用户的使用提供了极大方便。

This paper introduces a kind of portable wind measuring device, the inner three axis acceleration sensor is used to measure the ship rolling and vertical swing information, wind direction and the real wind speed, wind direction. Through three axis accelerometer to measure the ship roll and pitch information, through the correlation algorithm to correct the measured wind speed and direction value. Within the integrated GPS module, through navigational speed, course information and resultant wind to really true wind speed. The pressure module and electronic compass module can provide different parameter to the user, convenient use of different users.
