摘要
风速风向仪主要有两种,一种是风杯式风速风向仪,存在的缺点是体积大,旋转部件长期会造成磨损,另一种就是超声波风速风向仪,存在的缺点就是成本高,技术复杂,国内技术被国外所垄断,摇杆式风速风向仪优化了结构,采用球形铰链机构,缩小了体积,设计原理简单,成本低,可以在恶劣天气工作等优点。
There are mainly two kinds of wind speed and direction meter: one is the wind cup type wind speed and direction meter, with its disadvantage being that the volume is large and the rotating parts will cause wear for a long time; the other is the ultrasonic wind speed and direction meter, the shortcomings of which are high cost and complex technology, and the domestic technology is monopolized by foreign countries. The rocker wind speed and direction meter has been optimized in structure, with a spherical hinge mechanism, a reduced volume, a simplified design principle, and low cost, and it can work in bad weather.
