Abstract: The invention relates to a protection device for protecting the connection between a detachable wired drone (1) and the wire (5) thereof. This device enables the plug (3) to be reused even when it has fallen many times from a great height and limits the risk of injury and electrocution of people. The device consists of a non-conductive envelope surrounding the electrical contacts of the plug (3), a procedure or a mechanical system that cuts off the power when the plug (3) is detached from the drone (1), a system for mechanical protection against impacts, which can be an energy-dissipating envelope, a parachute-like system (4) for slowing down the fall, or the separation of the plug into a plurality of parts connected by a flexible element. The device according to the invention is particularly applicable to wired drones (1) in order to speed up movement outside the perimeter defined by the wire (5).

Abstract: A system including a drone, a wire and a docking station allowing the autonomous landing of the drone in degraded conditions. The docking station including a landing platform. The landing procedure includes stopping the automatic position control of the drone, producing a motor thrust higher than the weight of the drone, the automatic control of the attitude of the drone, and pulling upon the wire in order to bring the drone back to the platform. This system makes emergency landings possible, or landings under violent winds, or when the docking station is in movement on a vehicle, reducing material breakage.

Abstract: The present invention relates to a device for supplying electrical power to a wired system for a drone (1). The device according to the invention includes at least one power converter (4) on the ground and one power converter (2) at the level of the drone (1), regulation at the level of the converter on the ground ensures that the output voltage of the power converter (4) on the ground increases when the output current of the power converter (4) on the ground increases. The method according to the invention is intended for all wired drones, the wire (3) of which is used to supply electrical power to the drone (1).
