Abstract

The present invention discloses a three-dimensional wind field measurement system applicable to an unmanned aerial vehicle and a use method of the three-dimensional wind field measurement system. The three-dimensional wind field measurement system comprises a data acquisition device and a control system; the data acquisition device comprises a plurality of wind speed measuring devices and a wind speed acquisition support; each wind speed measuring device includes wind speed sensors and a wind speed sensor fixing mechanism; the wind speed acquisition support includes a base main body, upright columns and a top cover; the base main body includes an upper-layer base and a lower-layer base; the top surface of the upper-layer base is provided with the plurality of upright columns which are distributed circumferentially; the upright columns are provided with the wind speed measuring devices; the lower-layer base is provided with a rotation driving device for driving the upper-layer base to rotate; and the top surface of the upper-layer base and the bottom surface of the top cover are both provided with the wind speed measuring devices. With the three-dimensional wind field measurement system of the invention adopted, the measurement of a three-dimensional space wind field at a specific area around the unmanned aerial vehicle can be realized. The three-dimensional wind field measurement system has the advantages of simple structure, convenient operation, easiness in arrangement and high applicability.

Description

technical field [0001] The invention relates to the field of meteorological monitoring equipment for unmanned aerial vehicles, in particular to a three-dimensional wind field measurement system suitable for unmanned aerial vehicles and a method for using the same. Background technique [0002] UAVs are simple in structure and low in cost, and are now widely used in agricultural purposes such as pesticide spraying and flower pollination. Although UAVs are flexible and maneuverable and have incomparable advantages over traditional agricultural machinery, since the height of agricultural UAV operations is generally 3-10 meters away from the crop canopy, the rotor wind field will inevitably directly affect the crops in the field. On the canopy, the coverage width of the wind field, the size of the wind speed in each direction in the wind field, and the distribution of the wind field will directly affect the field operation effect of agricultural drones. The research on aerodynam...
