Abstract

The invention discloses an ultrasonic three-dimensional wind measuring method and a three-dimensional ultrasonic anemometer. An ultrasonic three-dimensional wind measurement method, respectively setting three pairs of ultrasonic probes, that is, a first pair of horizontal probes and a second pair of horizontal probes parallel to the horizontal plane, and a pair of vertical probes perpendicular to the horizontal plane; The probe receives the propagation time of the ultrasonic waves sent by the other party; according to the measured propagation time and the distance between the two probes facing each other in three pairs, the three-dimensional wind speed and direction of the natural wind can be obtained. The invention can accurately calculate the three-dimensional wind speed and direction, has no moving mechanical parts, and has a heating device, does not require frequent maintenance, and is applicable to all-weather wind speed and wind direction measurement under severe environmental conditions.

Description

technical field [0001] The invention relates to the field of wind speed and direction measurement, in particular to a three-dimensional ultrasonic anemometer and an ultrasonic three-dimensional wind measurement method. Background technique [0002] At present, the existing anemometers mainly include mechanical anemometers, thermal anemometers and ultrasonic anemometers. Among them, the mechanical anemometer has moving mechanical parts and has relatively high requirements for the measurement environment. It cannot work normally in dusty or low-temperature freezing environments, and its service life is short due to the wear and tear of moving parts. In addition, limited by the mechanical structure and measurement principle, the measurement accuracy of the mechanical anemometer is low. [0003] The basic principle of the thermal anemometer is to heat the object placed in the airflow to a certain temperature, and calculate the wind speed by calculating the heat loss of the obje...
