Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] Aiming at the problem that when the rotor of a multi-rotor aircraft is broken, the motor corresponding to the broken rotor will fail or the rotor will be damaged, and the aircraft will fall and cause damage to the aircraft and expensive equipment mounted. The present invention proposes a multi-rotor A method and system for maintaining a safe and stable flight and landing of an aircraft after a propeller breaks.

[0025] see figure 1 as shown, figure 1 It is a flow chart of the propeller breaking protection control method of the multi-rotor aircraft of the present invention.

[0026] The p...

Abstract

The invention provides a protection method and system for propeller breakage of multi-rotor aircrafts. When any rotor of a multi-rotor aircraft is detected to be abnormal, the power limits of the multi-rotor aircraft in the pitch and roll directions are increased, and thus, the output power limits of the other normal rotors in the flight height direction and the flight yaw direction can be reducedunder the condition of fixed total power. Therefore, the normal posture of the aircraft can be temporarily stabilized, there is enough time for forced landing or other control of the aircraft, and damage to the aircraft itself or other damage caused by direct falling of the aircraft is avoided.

Description

technical field [0001] The invention relates to a multi-rotor aircraft, in particular to a method and a system for protecting a multi-rotor aircraft against broken propellers. Background technique [0002] At present, multi-rotor aircraft are widely used in various fields. Multi-rotor unmanned aerial vehicles can be mounted with professional gimbals, high-definition camera equipment and emergency rescue equipment, and can be used in professional aerial photography, rescue, electric cruise, sports live broadcasting and other fields. market demand. [0003] Each rotor of the existing multi-rotor aircraft is driven by a motor to provide power. When the motor of a certain rotor fails or the rotor is damaged, the aircraft will fall, which will cause damage to the aircraft and expensive equipment mounted, and even cause harm to people. harm. [0004] Therefore, after the multi-rotor aircraft loses the power of a certain rotor, it is particularly important that it can still conti...
