Embodiment Construction

[0023] In the following description, for the purpose of illustration rather than limitation, specific details such as a specific system structure, interface, technology, etc. are proposed for a thorough understanding of this application. However, it should be clear to those skilled in the art that this application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known devices, circuits, and methods are omitted to avoid unnecessary details from obstructing the description of this application.

[0024] For ease of understanding, an application scenario of the return-to-home control method is described first.

[0025] UAVs are used to fly on set routes such as inspections and information collection. Due to the limited battery power of the drone, the drone may run out of power during the flight without endurance. Therefore, if the drone is flying on the set route, if the battery is found to be insufficient, it n...

Abstract

The invention discloses a return voyage control method and a return voyage control device of an unmanned aerial vehicle, and the unmanned aerial vehicle. The method comprises the following steps: detecting whether the current electric quantity of the unmanned aerial vehicle reaches a first electric quantity threshold value; if the current electric quantity of the unmanned aerial vehicle reaches the first electric quantity threshold value, determining the distance relation between the current position of the unmanned aerial vehicle in a set air line and a set waypoint; and according to the distance relation, controlling the unmanned aerial vehicle to continuously fly according to the set air line until a second electric quantity threshold value and then return or directly controlling the unmanned aerial vehicle to return. By the method, the effective utilization rate of the electric quantity of a battery can be increased.

Description

Technical field [0001] The present invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle's return home control method, device and unmanned aerial vehicle. Background technique [0002] At present, with the rapid development of science and technology, unmanned aerial vehicles have been gradually used in various fields such as aerial photography, exploration, transportation, military, data collection, and forest fire prevention. Usually, drones are set to perform inspections on planned routes to monitor the surrounding environment under the route. [0003] Since the power of the drone is limited, during the inspection process, if the drone detects that its own power is insufficient, it needs to return to the home for charging. The existing detection method is to set a flight control low-power return voltage for the drone. During the inspection, if the battery voltage is found to be lower than the set voltage, the inspection is stoppe...
