Abstract

[Problem] To provide a crash detection device, a flying body crash detection method, a parachute or paraglider deployment device, and an airbag device capable of improving safety reliability. [Solution] This flying body crash detection device comprises: a detection unit capable of detecting the flight state of a flying body; a calculation unit capable of determining, on the basis of the flight state data for the flying body obtained by the detection unit, whether the flight state of the flying body is abnormal; and an abnormality signal output unit capable of outputting an abnormality signal to the outside if the calculation unit determines that the flight state of the flying body is abnormal. The calculation unit acquires data from the detection unit at a sampling frequency of 1 kHz or more and if the data is at least a certain preset threshold value, determines whether the data is indication of an abnormal flight state for the flying body or noise constituting unnecessary data. If the calculation unit determines the former, then the flight state of the flying body is determined to be abnormal.

Description

technical field [0001] The invention relates to a fall detection device mounted on an aircraft, a method for detecting the fall of the aircraft, a parachute or paraglider deployment device and a safety air bag device. Background technique [0002] In recent years, along with the development of autonomous control technology and flight control technology, the industrial use of aircraft with multiple rotors called unmanned aerial vehicles, for example, has been accelerated. For example, the UAV rotates a plurality of rotors in a balanced manner at the same time, ascends and descends by increasing and decreasing the number of rotations of the rotors, and advances and retreats by tilting the body by increasing and decreasing the number of rotations of the rotors. It can be predicted that this kind of aircraft will develop in the world in the future. [0003] On the other hand, the risk of crash accidents of the above-mentioned aircraft is considered to be very dangerous, which h...
