Description

[0001] technical field

[0002] The invention relates to the technical field of wind speed and direction measurement, in particular to a mobile ultrasonic anemometer and a method for measuring wind speed and direction under mobile conditions by using ultrasonic waves combined with speed and direction measuring components. Wind speed and direction measuring instruments in mobile or fixed situations such as on-site gas monitoring. Background technique

[0003] At present, the existing anemometers are mainly fixed anemometers; and in the fields of environmental detection, navigation, industrial air duct detection, measurement of dangerous gases and construction of mobile weather stations, due to the direction and speed of the detection system itself etc. are always moving, and the traditional fixed anemometer does not measure and correct the direction and speed. Therefore, the fixed anemometer cannot meet the requirements of the mobile system in the application environment of s...
