Problems solved by technology

During the flight of a small UAV, any abnormality of any part or link may cause the aircraft to lose control and crash, thereby causing damage to the airframe itself and onboard equipment. Philippines, crash could cause huge property value if it happens
The parachute in the existing UAV protective equipment also plays a certain protective role, but because the existing parachute unfolds slowly or cannot be deployed, it cannot achieve the proper protective effect

Abstract

The invention relates to an unmanned aerial vehicle crash protection system and a control method and belongs to the technical field of unmanned aerial vehicles. The system is specifically characterized in that an inertial sensor is installed on a body of the unmanned aerial vehicle; a crash and slow descent device is arranged on the top of the body; and a crash protection controller as well as anemergency power supply and a parachute are arranged in a shell of the crash and slow descent device. When weightlessness of the unmanned aerial vehicle is detected, the parachute is rapidly inflated by a high-pressure helium bottle, so that the parachute can be rapidly unfolded to form. Moreover, by utilizing the characteristic of low helium density, crashing impact force of the unmanned aerial vehicle can be greatly buffered, so that the unmanned aerial vehicle can smoothly land, and damage of the unmanned aerial vehicle can be effectively avoided.

Description

technical field [0001] The invention relates to a drone fall protection control system and control method, belonging to the technical field of drones. Background technique [0002] At present, small drones at home and abroad have been widely used in civilian and military fields, such as disaster monitoring in disaster areas, aerial photography of TV stations, power line inspection, weather detection, target detection, etc. During the flight of a small UAV, any abnormality of any part or link may cause the aircraft to lose control and crash, thereby causing damage to the airframe itself and onboard equipment. Philippines, once a crash occurs, it will cause huge property value. The parachute in the existing UAV protection equipment also plays a certain protective effect, but because the existing parachute is slow to expand or cannot be deployed, it cannot have the proper protective effect. Contents of the invention [0003] In order to solve the technical problems existing...
