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...

[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 ships, automobiles, and wind farms. The application of wind speed and direction measurement in the environment; and the traditional mechanical anemometer cannot work normally in the northern sandstorm weather due to the sealing problem, and the moving parts will be stuck due to freezing in the low temperature environment; At the same time, due to the shortcomings of mechanical wear and tear, the mechanical anemometer reduces the service life of the instrument; the thermal anemometer is not suitable for measuring slightly higher wind speeds because it is easily affected by environmental temperature changes; the ultrasonic anemometer used in recent years Anemometer, due to the use of 8 / 16-bit and other low-level single-chip microcomputers as microprocessors, the system will cause certain limitations and errors in data processing, communication, and measurement accuracy; Wind can cause large measurement errors
