AI Technical Summary
Existing three-dimensional anemometers use a vertically orthogonal transducer array design, which ignores the influence of turbulence interference, resulting in reduced wind measurement accuracy and making drones prone to loss of control in strong wind environments.
The design employs a non-positive exchanger array, with four ultrasonic probes distributed at the vertices of a regular tetrahedron. Wind speed and direction are calculated using the time difference method, while two additional sets of probes provide data compensation. Furthermore, in the event of a probe fixing rod breakage, a flexible thin rod and a fixed chassis structure are used to retrieve the probe, preventing objects from falling from heights.
It improves the accuracy of wind speed and direction measurement, reduces the impact of turbulence on wind measurement, protects the safety of drones in strong wind environments, prevents loss of control, and facilitates the recovery and reuse of the probe.
