Problems solved by technology

[0002] The protection of the out-of-control state of the rotor UAV has always been a hot issue in the research field of the rotor UAV. The rotor UAV has the characteristics of multi-variable, nonlinear, strong coupling, etc., and it is difficult to control, and the UAV is in flight. It is easy to encounter various uncertain and unexpected failures such as wind disturbance and motor vibration. If any part of the drone fails or makes mistakes, the consequences will be unimaginable
The existing out-of-control return-to-home protection method can only protect UAVs in the presence of GPS signals, and cannot meet the protection requirements for rotary-wing UAVs

Embodiment 1

[0052] Embodiment 1. An intelligent out-of-control protection system for a rotor-type UAV, including a power supply, a control chip, an attitude sensor, a height sensor, a first steering gear, a second steering gear, a catapult, a self-throwing parachute, and shock-absorbing automatic inflation Air cushion and automatic inflation device.

[0053] The power supply is used to supply power to the control chip, the attitude sensor, the height sensor, the first steering gear, the second steering gear and the catapult. Such as figure 1 A specific implementation method is given. The 6V power supply is composed of four 1.5V rechargeable batteries, which are responsible for supplying power to the entire system. In practice, any power supply that can supply power to the system can be used. In this embodiment, in order to ensure The system uses a separate power supply.

[0054] The attitude sensor and height sensor are used to obtain the attitude data and height data of the rotor UAV, ...

Embodiment 2

[0074] Embodiment 2, a kind of rotor type unmanned aerial vehicle intelligent out-of-control protection method, comprises the following steps:

[0075] The first step: set up the intelligent out-of-control protection system of the rotor type unmanned aerial vehicle as described in embodiment 1;

[0076] The second step: According to the flight motion law of the rotor UAV, through the actual flight test, obtain the threshold information of the attitude data of the rotor UAV during flight, including the threshold information of angle, angular velocity and acceleration;

[0077] Such as Figure 12 It is the determination of the out-of-control threshold of the rotor UAV angle, and then it can be obtained that when the rotor aircraft is flying normally, its pitch angle and roll angle are between -40 degrees - +40 degrees, so the out-of-control threshold angle is determined as 40 Spend.

[0078] Such as Figure 13 It is the determination of the angle out-of-control threshold of t...

Abstract

The present invention disclosed a rotor -type drone intelligent outlet protection system, including the following devices: the power supply is used to control the chip, attitude sensor, height sensor, first steering gear, second steering gear, and projector power supply;The height sensor is used to obtain the gesture data and height data of the rotor -type drone, and sends the posture data and high data to the control chip; the control chip is used to analyze the attitude data and high data, and issue a control signal to the first rudder to the first rudderThe aircraft and the second steering gear; the first steering gear controls the opening and shutdown of the maggots; the second steering gear controls the automatic inflatable device to reduce the air cushion inflatable;; The ejaculation is fixed at the top of the rotor -type drone; the self -throw parachute is installed inside the rebounder.

Description

technical field [0001] The invention belongs to the field of control and protection of a rotary-wing unmanned aerial vehicle, and relates to an intelligent out-of-control protection system and a method thereof for a rotary-wing unmanned aerial vehicle. Background technique [0002] The protection of the out-of-control state of the rotor UAV has always been a hot issue in the research field of the rotor UAV. The rotor UAV has the characteristics of multi-variable, nonlinear, strong coupling, etc., and it is difficult to control, and the UAV is in flight. It is easy to encounter various uncertain and unexpected failures such as wind disturbance and motor vibration. If any part of its drone fails or makes mistakes, the consequences will be unimaginable. The existing out-of-control return-to-home protection methods can only protect UAVs in the presence of GPS signals, and cannot meet the protection requirements for rotary-wing UAVs. [0003] The self-throwing parachute and shoc...
