Recycling and releasing device applied to child-mother unmanned aerial vehicle and control method of recycling and releasing device

Abstract

The invention discloses a recycling and releasing device applied to a child-mother unmanned aerial vehicle and a control method. In the device and the method, the relative position relation between the child unmanned aerial vehicle and the mother unmanned aerial vehicle is accurately positioned through mutual cooperation of an infrared receiving panel and an infrared light-emitting diode, and a mechanical claw is driven to move horizontally through a horizontal moving platform to find a grabbing position, so that the child unmanned aerial vehicle can be quickly grabbed through the mechanical claw, and the recovery operation of the child unmanned aerial vehicle is completed; when the child unmanned aerial vehicle is released, a rotor wing of the child unmanned aerial vehicle is started in advance, so that the child unmanned aerial vehicle basically achieves self hovering, then the mechanical claw is released. The device is high in grabbing speed, high in automation degree, stable and reliable.

Description

technical field [0001] The present invention relates to a four-rotor UAV recovery control device and a corresponding recovery method, in particular to a four-rotor UAV recovery and release device applied to a mother-child UAV and a control method thereof. Background technique [0002] The mother-child UAV system is a system in which a large UAV carries one or more small UAVs to fly, and can realize the capture and release of large UAVs to small UAVs. The recovery and release device is a bridge connecting the sub-machine and the main machine. It is installed on the main machine and can track, recover and release the sub-machine. In order to meet the needs of rapid search, large-scale search, effective treatment, and reduced collateral damage for battlefield rescue, the mother-child drone needs to have the characteristics of long battery life, high mobility, and strong adaptability to complex environments. The design of the recovery and release device needs to fit the charact...

Problems solved by technology

[0003] However, in some existing Alphabet UAV systems, when the sub-machine and the main machine are all rotor-type UAVs, its open structure is greatly affected by wind force and oscillation, which is not conducive to the stability of the platform's attitude and high-speed forward flight. In addition, the open platform structure is only applicable to the parent-child UAV whose parent aircraft is a quadrotor UAV. If the parent aircraft is changed to a fixed-wing UAV, it will no longer be applicable.

[0004] In addition, the recovery and release structure of the parent-child drone system has low recovery efficiency, and generally only 4 drones can be recovered within 30 minutes; some recovery targets are large in size, such as the weight of the "elf" drone. Between 250-500kg, only suitable for recovering fixed-wing drones, not suitable for recovering quadrotor drones with a battery life of only about 20 minutes and a weight of only about 3kg
