Embodiment 1

[0031] Such as figure 1 As shown, a UAV flight control method provided in the embodiment of the present application, the method includes:

[0032] Step 110: Obtain a first flight state of the drone, where the first flight state includes a first flight speed.

[0033] Specifically, when the UAV is in a flying state, the flight speed of the UAV during normal flight is obtained. The flight state may be the flight state in the case of performing a variety of different tasks, for example: map surveying, forest surveying, emergency rescue and disaster relief, logistics express delivery, high-altitude photography and other situations. Generally speaking, the first flight state of the drone may include a variety of state information, such as flight speed, such as flight altitude, such as the operating conditions of various devices in flight, and the like. In the embodiment of the present application, in step 110, the first flight speed information of the UAV is obtained.

Embodiment 2

[0048] The embodiment of the present application also provides a UAV flight control method, the method also includes:

[0049] judging whether the UAV flies into the safe range; when the UAV does not fly into the safe range, execute the first instruction;

[0050] When the unmanned aerial vehicle flies into the safe range, the second instruction is executed, and the second instruction is used to instruct the unmanned aerial vehicle to fly out of the safe range, specifically, when the unmanned aerial vehicle is executing When the first instruction was completed, it still flew into a safe range. For example, due to the increase in gravity caused by the drone’s load, the buffer range was too small, which made the buffer distance insufficient, causing the drone to fly into a safe distance. Or because the UAV is flying downwind due to climate reasons, it can also cause the UAV to fly into a safe range. Under the above circumstances, it can be determined that when the UAV flies int...

Embodiment 3

[0052] The embodiment of the present application also provides a UAV flight control device, the UAV includes a distance sensor, wherein the device includes:

[0053] A first obtaining unit 11, the first obtaining unit 11 is used to obtain a first flight state of the drone, the first flight state includes a first flight speed;

[0054] A second obtaining unit 12, the second obtaining unit 12 is used to obtain the safety range of the drone;

[0055] A first determination unit 13, the first determination unit 13 is configured to determine the buffer range of the UAV according to the first flight speed;

[0056] A third obtaining unit 14, the third obtaining unit 14 is used to obtain the target distance from the obstacle according to the distance sensor;

[0057] The second determination unit 15 is configured to determine that the UAV executes a first instruction according to the target distance, the safety range, and the buffer range, and the first instruction is used to make T...

Abstract

The present invention provides a flight control method for an unmanned aerial vehicle and belongs to the unmanned aerial vehicle technical field. The unmanned aerial vehicle comprises a distance sensor. The method includes the following steps that: the first flight state of the unmanned aerial vehicle can be obtained, wherein the first flight state contains a first flight speed; the safe range of the unmanned aerial vehicle is obtained; the buffer range of the unmanned aerial vehicle is determined based on the first flight speed; a target distance to an obstacle is obtained according to the distance sensor; and based on the target distance, the safe range and the buffer range, it is determined that the unmanned aerial vehicle performs a first instruction, wherein the first instruction is used for enabling the unmanned aerial vehicle to stop outside the safe range. With the flight control method for the unmanned aerial vehicle provided by the present invention adopted, the defect that the unmanned aerial vehicle tends to land in a safe range in the prior art can be eliminated; and the flight of the unmanned aerial vehicle can be effectively controlled, and the safety of the unmanned aerial vehicle and an operator can be improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a flight control method and device for an unmanned aerial vehicle. Background technique [0002] At present, drones are widely used in map surveying, forest surveying, emergency rescue, logistics express, high-altitude photography and other fields. [0003] With the development of drone technology, in order to ensure the safety of drones or operators in the prior art, a security mechanism for drones is set to ensure the safety of drones or operators. For example, set a safe range for the drone, and operate the drone when the drone detects the safe range. [0004] But, the inventor finds that there are following deficiencies in the prior art in daily work: [0005] When the UAV detects the safe range and executes the corresponding command, because the UAV needs a certain processing time, it often causes the UAV to fall into the safe range, which increases the ri...
