针对传统测风仪器无法直接用于移动条件下（如车载或船载时）的风速风向测量的问题，设计了一种可以在移动平台上应用的超声波风速风向测量系统。该系统使用超声波时差法测量平面内二维风向风速，同时使用霍尔传感器和电子罗盘测量基座的移动速度和方向，通过微处理器对测得的风速风向进行修正，得到实际风速和风向。系统采用 ARM 作为核心控制器，提高了时差的测量精度，并降低了功耗。

Traditional anemometer can′t get correct results when it is placed in a moving base , such as a car or a ship . This paper introduces a new ultrasonic anemometer which can measure wind velocity , wind direction and it can be placed in a moving base . This instrument gets velocity and direction of wind using ultrasonic transit-time difference measurement and gets velocity and direction of base using hall sensor and electronic compass . The microcontroller analyses and calculates these data to get correct wind velocity and direction . This instrument takes ARM controller as it core , which improves measurement accuracy and reduces power dissipation .
