Middle and small sized no-manned machine reclaiming positioning apparatus

Abstract

The invention discloses a small and medium-sized unmanned aerial vehicle recycling and positioning device, which is applied in the recycling and positioning of the small and medium-sized unmanned aerial vehicles after the parachute landing. The device comprises a vehicle-carrying GPS receiver, a vehicle-carrying wireless mobile communication module, a recycling controller and a parachute landing recycling device which are arranged on an unmanned aerial vehicle and a ground GPS receiver, a ground wireless mobile communication module and a ground processing display module of a ground recycling and poisoning device, as well as a radio beacon on the unmanned aerial vehicle and a radio direction finding device of the ground recycling and positioning device. The small and medium-sized unmanned aerial vehicle recycling and positioning device utilizes the vehicle-carrying wireless mobile communication module and the ground wireless mobile communication module and uses a civil wireless mobile communication network to expand the coverage of the transmission of the recycling and the positioning information; the radio direction finding positioning is adopted to solve the problem that the positioning is unable when the GPS receiver works abnormally after the parachute landing of the unmanned aerial vehicle; the small and medium-sized unmanned aerial vehicle recycling and positioning device can reduce the recycling working amount of the unmanned aerial vehicle, accelerate the recycling speed and have a wide coverage and low cost of the device, which can not only be applied independently, but also be combined with the prior art for application.

Description

technical field [0001] The invention relates to a recovery and positioning device for small and medium-sized unmanned aerial vehicles, which belongs to the technical field of communication. Background technique [0002] Small and medium-sized UAVs are widely used in both military and civilian fields, such as military reconnaissance, oil pipeline inspection, urban planning, atmospheric environment monitoring, etc. Small and medium-sized UAVs are remotely controlled by the ground control station, and the two communicate through a two-way measurement and control link. The ground control station uploads various instructions to control the UAV, and the UAV controls various parameters and mission equipment The obtained data is sent to the ground control station by the onboard computer. The onboard computer on the UAV, the airborne measurement and control station, the ground station computer and the ground measurement and control station of the ground control station constitute the...

Problems solved by technology

However, when the GPS fails to work normally due to the overturning of the fuselage after the UAV is grounded, or it falls outside the communication range of the ground control station after parachute landing, it can only be based on the UAV’s position and opening when the parachute command is issued. The height of the umbrella determines the approximate range of the touchdown, and then it is necessary to arrange for recovery personnel to patrol the area reciprocally to find and recover the drone, which is time-consuming and laborious
