Problems solved by technology

At present, some unmanned aerial vehicles are used for aerial photography or agricultural operations. The underside of the unmanned aerial vehicles is equipped with loads such as precision pan / tilts, expensive cameras, or heavy sprayers. Once the unmanned aerial vehicles lose power or part Power, in the process of forced landing, often UAV and load will be greatly damaged, and may threaten the safety of people or property on the ground

Embodiment approach

[0163] As a specific implementation manner, the motion state includes the speed of the load;

[0164] The processor 802 is specifically configured to issue a control command to open the parachute when the speed of the load is greater than or equal to a preset speed threshold after the load is separated from the UAV.

[0165] As a specific implementation manner, the motion state includes the acceleration of the load;

[0166] The processor 802 is specifically configured to issue a control command to open the parachute when the acceleration of the load is greater than or equal to a preset acceleration threshold after the load is separated from the UAV.

[0167] In some embodiments, the processor 802 is specifically configured to issue a control command to open the parachute after the load falls a preset distance or after the load falls for a preset time.

[0168] In some embodiments, the processor 802 is configured to control the power system of the unmanned aerial vehicle, and...

Abstract

The invention provides an apparatus, a method and a piece of equipment for controlling forced landing. The method for controlling forced landing comprises the following steps: obtaining a signal for indicating power loss or partial power loss of an unmanned aerial vehicle; when the signal for indicating power loss or partial power loss of an unmanned aerial vehicle is obtained, separation of a load which is mounted on the unmanned aerial vehicle and the unmanned aerial vehicle is controlled according to a preset strategy, so that the load and the unmanned aerial vehicle are separately landed in forced landing. According to the mode, during forced landing, the weight at the side of the unmanned aerial vehicle is reduced, in order to increase success rate of forced landing of the unmanned aerial vehicle, and on the other hand, damage on the load due to spinning of the unmanned aerial vehicle is prevented, winding of parachute cords of a parachute due to propeller of the unmanned aerial vehicle is prevented, and the load can be effectively protected.

Description

technical field [0001] The invention relates to the field of control of unmanned aerial vehicles, in particular to a device, method and equipment for controlling forced landing. Background technique [0002] When the unmanned aerial vehicle cannot continue to fly in an unexpected situation, it needs to make an emergency landing on the ground or water to reduce the falling speed of the unmanned aerial vehicle. This process is called forced landing. At present, some unmanned aerial vehicles are used for aerial photography or agricultural operations. The underside of the unmanned aerial vehicles is equipped with loads such as precision pan / tilts, expensive cameras, or heavy sprayers. Once the unmanned aerial vehicles lose power or part Power, in the process of forced landing, often UAV and load will be greatly damaged, and may threaten the safety of people or property on the ground. Contents of the invention [0003] Embodiments of the present invention provide a device, met...
