Abstract

The invention discloses an autonomous safety anti-falling device for an unmanned aerial vehicle and a control method of the autonomous safety anti-falling device. The device comprises a fixing frame, a shell, an MEMS nonmetal mass block, a metal contact, a spring, a gas generation device, a safety airbag, a fixing device, a resistor, a button switch, an electric ignition head, an internal power source and a control circuit. A mechanical structure is adopted, the influence of a circuit of the unmanned aerial vehicle is small, and the reliability is high; during normal use on the ground, the safety anti-falling device is in a safe state, so that the fault-tolerant rate of operation of ground workers is increased; in the normal flight process, the safety anti-falling device is in a to-be-operated state, and the safety anti-falling device can quickly pop up the safety air bag when a flight control system fails, so that on one hand, the safety of personnel in a flight path is protected, and on the other hand, the safety of the unmanned aerial vehicle body is protected; and if no situation occurs and safe landing occurs, the safe anti-falling device is protected again, and use next time is facilitated.

Description

technical field

[0001] The invention relates to the field of drone safety devices, in particular to an autonomous safety anti-drop device for drones and a control method thereof. Background technique

[0002] With the rapid development of the current drone industry, people have increased the research on drone technology, making it widely used in aerial photography, urban freight, national defense and security and other fields. Although the UAV flight control technology has gradually matured, it can fly for a long time and long distance, and the application scenarios and functions are more diversified, but the safety problem of UAVs has not been effectively solved, whether it is a well-known manufacturer or an OEM. Assembling, crashes have occurred due to technical failures and other reasons. As drones are increasingly used in crowded scenes, crashes caused by equipment failures, emergencies and other reasons have greatly threatened the surrounding population. Causing person...
