Problems solved by technology
Among them, the flow of airflow on the surface of the barometer will reduce its measurement accuracy, which in turn will lead to inaccurate height estimation and height determination of the drone, affecting the flight of the drone, and even the phenomenon of the drone dropping height.

Embodiment Construction
[0037] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.
[0038] In the present disclosure, unless otherwise stated, the use of directional words such as "inner and outer" refers to the inner and outer parts relative to the contour of the component itself; the purpose of using the words "first, second" and the like It is to distinguish different parts, and it does not have order and importance. Furthermore, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings refer to the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure, and should not be construed as limiting the present discl...

The present disclosure relates to an unmanned aerial vehicle and its flight control device, as well as a voltage stabilization structure for a barometer. The voltage stabilization structure includes a first voltage stabilization part and a second voltage stabilization part both made of opaque materials. Both the first pressure-stabilizing portion and the second pressure-stabilizing portion have a cylindrical shape with a closed end and an open end, and each defines a channel extending between the closed end and the open end, and a useful channel is defined in the channel. In the accommodating space where the barometer is placed, the first voltage stabilizer part and the second voltage stabilizer part are sleeved with each other in such a way that the open end of one of them is located in the channel of the other, and the first stabilizer There is a gap between the pressure-stabilizing part and the second pressure-stabilizing part, so that the accommodating space communicates with the space outside the pressure-stabilizing structure. The voltage-stabilizing structure has a good voltage-stabilizing effect.
Description
technical field [0001] The present disclosure relates to the technical field of barometers, and in particular, to an unmanned aerial vehicle, a flight control device thereof, and a voltage stabilization structure for a barometer. Background technique [0002] The flight control device of the UAV can stabilize the flight attitude of the UAV and control the autonomous or semi-autonomous flight of the UAV. It is the brain of the UAV. The UAV's flight control device obtains data from various sensors mounted on the UAV, and performs arithmetic processing on these data to control the flight of the body. For example, the UAV's flight control device uses the barometer to integrate other sensors to achieve altitude estimation And fixed height, among which, the measurement accuracy of the barometer has a huge impact on the flight control device to control the flight of the body. [0003] The working principle of the barometer is to determine the height of the drone by measuring the s...
