Protection control method of air vehicle, device and air vehicle

Abstract

The present invention provides a protection control method of an air vehicle, a device and an air vehicle, wherein the method comprises the steps of detecting the flight state of the air vehicle (S101); when the flight state of the air vehicle is detected to be a recycle state, generating a recycle trigger signal, and sending the signal to an external protection device for the air vehicle, thereby triggering the external protection device to start the safety protection to the air vehicle (S102), wherein the flight state detection of the air vehicle comprises analyzing the flight data of the air vehicle, detecting a ground control signal received by the air vehicle, if the analysis result to the flight data is abnormal, or the detected ground control signal is a recycle trigger signal, determining the flight state of the air vehicle as the recycle state. The method can avoid an error starting of a safety device in the air vehicle more effectively, better guarantees the normal flight of the air vehicle, and reduces the damage to the air vehicle and the outside world when the air vehicle falls down rapidly due to the system failure or other reasons.

Description

technical field [0001] The invention relates to the technical field of aircraft safety, in particular to an aircraft protection control method, device and aircraft. Background technique [0002] With the continuous development of flight technology, various types of aircraft with different functions have been widely used in military and civilian fields, and small unmanned aerial vehicles have been widely used in geological disaster monitoring, forestry, etc. Fire prevention, aerial surveying and mapping, environmental monitoring and target detection and other fields. [0003] During the flight, the aircraft may crash due to weather conditions, terrain environment, component failure of the aircraft itself, and insufficient power. In order to prevent the aircraft from crashing and being damaged, in the prior art, a parachute is generally used to ensure the safe landing of the aircraft. [0004] In the existing UAV parachute control technology, the aircraft can use information...

AI Technical Summary

Problems solved by technology

[0004] In the existing UAV parachute control technology, the aircraft can use information such as airspeed and ground speed to estimate the horizontal wind speed, wind direction and possible other weather conditions in the air, so as to determine the location and timing of parachute opening. However, this situation is vulnerable to The instantaneous strong wind that does not affect the flight leads to misjudgment, causing the normal flying aircraft to open the parachute by mistake
