Description

technical field

[0001] The invention belongs to the technical field of wind force detection, in particular to an ultrasonic wind sensor with a heating function. Background technique

[0002] Wind energy is the kinetic energy generated by air flow. The quality of the wind resources in the wind field always affects the operation of the wind turbine. Wind speed and wind direction are important factors in the wind field. The accuracy of the measurement directly affects the research on the characteristics of the wind field. The commonly used measurement methods of wind speed and direction mainly include wind vane, wind cup, wind wheel, ultrasonic wave, etc. At present, the measurement methods of wind speed and direction at home and abroad are mainly based on ultrasonic measurement method. Because of the advantages of simple installation, convenient maintenance, and It has the characteristics of high measurement accuracy and is widely used in industrial production and scientific e...
