In order to measure the wind speed and direction of natural wind accurately, a wind speed and direction measurement method is proposed based on the principle of wind pressure difference. According to the surface pressure distribution curve of subcritical flow around the cylinder, the circumferential array distribution of six cylindrical pipes is designed. The dynamic pressure of six cylindrical pipe orifices is measured by six high-precision differential pressure sensors, and the maximum value and the maximum value of the adjacent pipe are selected to calculate the wind speed and direction. In addition, the measurement results of anemometer, cup anemometer and ultrasonic anemometer are compared in the natural environment. The results show that the anemometer designed in this paper has the advantages of fast response, high precision, large range, intelligence and long working time, which is suitable for the measurement of heavy wind direction in the field test environment.
