Embodiment 1

[0023] figure 1 It is a flow chart of a UAV flight control method provided in Embodiment 1 of the present invention, which can be applied to the automatic return control of UAVs near the no-fly area. The flight control device can be implemented by means of software and / or hardware, and can generally be integrated into the flight control computer of the drone.

[0024] Wherein, the execution timing of the flight control method of the UAV can be during the entire flight process of the UAV, or when the flight area of ​​the UAV meets the set conditions, for example, when the UAV flies to After the geographic location is set (there is a no-fly area near the geographic location), the flight control method of the drone is executed, which is not specifically limited in this embodiment.

[0025] Such as figure 1 As shown, the method of this embodiment specifically includes:

[0026] S110. If it is determined that the real-time remaining fuel volume of the drone cannot meet the real-...

Embodiment 2

[0046] figure 2 It is a flowchart of a flight control method for a UAV provided in Embodiment 2 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiment, wherein, the current flight route of the UAV will be searched for and the The safe return point adjacent to the current position is used as the target safe return point, specifically:

[0047] Find the safe return point adjacent to the current position on the current forward route and the current reverse route of the drone respectively; use a safe return point with a shorter total voyage of the safe return route as the target safe return point.

[0048] Further, before using a safe return point with a shorter safe return route as the target safe return point, it also includes: calculating the total voyage of the safe return route from the current position of the drone to the landing segment via the safe return point.

[0049] Such as figure 2 As shown, the method of this embodim...

Embodiment 3

[0075] Figure 4 It is a schematic structural diagram of a flight control device for a drone provided in Embodiment 3 of the present invention, which is applicable to the automatic return control of the drone near the no-fly area, and the device can be realized by software and / or hardware. And generally can be integrated in the flight control computer of the UAV. Such as Figure 4 As shown, the flight control device of the UAV specifically includes: a safe return point acquisition module 410 and an automatic return control module 420 . in,

[0076] The safe return point acquisition module 410 is used to obtain the target safe return point according to the current position of the drone if it is determined that the real-time remaining fuel quantity of the drone cannot meet the real-time remaining range;

[0077]The automatic return control module 420 is configured to control the UAV to automatically return via the target safe return point according to the safe return route co...

Abstract

An embodiment of the invention discloses a UAV flight control method, a UAV flight control device, equipment and a storage medium. The UAV flight control method comprises the steps of: acquiring a target point of safe return according to a current position of a UAV when determining that the real-time remaining oil quantity of the UAV cannot satisfy the real-time range-to-go; and controlling the UAV to return automatically by means of the target point of safe return according to a safe return route corresponding to the target point of safe return. The UAV flight control method and the UAV flight control device guarantee the flight safety of the UAV when the UAV automatically returns, and effectively avoid the problem that the UAV enters a no-fly zone accidentally.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of unmanned aerial vehicles, and in particular to a flight control method, device, equipment and storage medium of an unmanned aerial vehicle. Background technique [0002] A drone is an unmanned aerial vehicle operated by a radio remote control device or its own program control device. When the UAV is flying in the air, the flight control computer needs to monitor the remaining fuel of the UAV at all times to avoid the situation that the remaining voyage cannot be met due to the low remaining fuel. [0003] At present, when the flight control computer detects that the remaining fuel is not enough to support the remaining voyage, it controls the UAV to return automatically. The automatic return strategy is usually to control the UAV to fly directly to the landing segment according to the shortest path for landing. However, the flight route of the UAV during the automatic return pro...
