矢量风速仪的设计

Design of 3D vector anemometer

为了解决机械式风速仪对方向测量的局限性,使用了单向叶轮传感器的矢量三维风速仪,风速传感器采用叶轮带动空心杯电机的结构,通过单片机对三维组合单向速传感器进行采集和风速矢量合成,实现了对风的大小和方向的测量.实验结果表明:该设计在对风速矢量的二维测量上,风速大小和方向的测量均具有很高的可靠性;在对风速矢量的三维测量上,风速大小的测量值也比较精确,风速方向的测量值误差比较小.

To overcome the limitations of direction measurement in common mechanical anemometer, a 3D vector anemometer with unidirectional impeller wind velocity sensor was designed. The wind velocity sensor used impeller driving eoreless motor. Using single chip computer to collect and analyze the data from the wind velocity sensor, the wind velocity and direction could he measured. The exper- imental results showed that our device had a high precision.
