摘　　要：风是气象预报中的一个重要的要素,准确地预报风速,对人们的生产生活都有一定的影响。二维超声风传感器是气象与工业中最重要的风速测量方式之一,在传统的超声波测风仪器的基础上,通过测量空气温湿度来进行准确的调节,补偿了雨雾等环境因素的影响,设计一种基于STM32处理器的200 k Hz全天候超声测风仪,通过实验证明:该装置可以实现全天候精确测量风速风向,测量误差小。Wind speed is an important factor meteorological forecast,accurate forecasting of wind speed,has certain influence on people＇s production and living. Two-dimensional ultrasonic wind speed sensor is one of the most important way of wind speed measurement in meteorology and industry,on the basis of traditional ultrasonic wave anemometer,accurately adjust by measuring temperature and humidity of air,compensate influence of environmental factors such as rain and fog,design a 200 k Hz ultrasonic anemometer all-weather based on STM32 processor,it is proved through experiment that the device can realize accurate wind speed and wind direction measurement,all-weather measurement error is small.
