Problems solved by technology

When the multi-rotor drone is hovering in the air, its main power is used to generate lift to overcome its own gravity, and the control torque in the horizontal direction is very small. If it encounters the push-off torque generated by a sudden horizontal shock wave at this time, The UAV cannot immediately eliminate the disturbance moment by tilting the fuselage, and most of the fire-fighting UAVs are connected to the ground connection pipeline. Under the traction of the pipeline, the UAV can lose its stable state instantaneously, causing it to lose control or crash. cause damage to people and property

Embodiment 1

[0051] A protective device applied to fire-fighting drones, such as figure 1 , 3 As shown, it includes an air pressure monitoring device 1, a control device 2 and a correction device 3; the air pressure monitoring device 1 is connected to the control device 2 with a signal, and the correction device 3 is connected to and controlled by the control device 2; the air pressure monitoring device 1 The air pressure data value of the environment where the UAV is located can be collected, the control device 2 receives the data value and judges the shock wave state that the UAV is currently facing according to the data value, and the control device 2 can control the correction device 3 to generate The reaction force against the shock wave. Specifically, it can effectively detect the state of the shock wave that the UAV is currently facing, and generate a reaction force relative to the shock wave through the correction device 3, assisting the UAV to maintain a stable attitude in the fa...

Embodiment 2

[0056] Embodiment 2 is a further improvement to Embodiment 1; further description, the same parts will not be repeated here, such as figure 1 , 2 As shown, a time acquisition device 8 is also included, and the time acquisition device 8 is connected to the control device 2 in signal; the time acquisition device 8 can collect the time T1 when the shock wave front reaches the first air pressure sensor 401, and the time T1 when the shock wave front reaches the second air pressure The time T2 of the sensor 501; the control device 2 obtains the time difference ΔT based on the time T1 when the shock wave front reaches the first air pressure sensor 401 and the time T2 when the shock wave front reaches the second air pressure sensor 501, and based on the pressure difference ΔP and the time difference ΔT Judge the shock wave status that the drone is currently facing. Specifically, by setting the time acquisition device 8, the accuracy of shock wave judgment is improved.

Abstract

The invention discloses a protection device applied to a fire-fighting unmanned aerial vehicle and a protection device control method, and relates to the field of unmanned aerial vehicle equipment. According to the protection device applied to the fire-fighting unmanned aerial vehicle and the protection device control method provided by the invention, the characteristic of high directivity during operation of the fire-fighting unmanned aerial vehicle is utilized, and the correction device is controlled to generate counter-acting force opposite to shock waves by monitoring the facing shock wave state of the unmanned aerial vehicle; the unmanned aerial vehicle is assisted to keep a stable posture when facing shock wave rapid disturbance, and the influence of explosive shock waves on the unmanned aerial vehicle is reduced.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle equipment, in particular to a protective device applied to a fire-fighting unmanned aerial vehicle and a control method for the protective device. Background technique [0002] Multi-rotor drones are favored by various industries due to their low requirements for take-off and landing conditions, simple control, and flexible maneuverability. Especially in the field of firefighting, firefighting drones have achieved outstanding results in the application of high-rise building fire extinguishing, firefighting equipment delivery, and personnel search and rescue. However, the use of fire-fighting drones has also exposed a series of disadvantages and shortcomings. Fire-fighting drones will inevitably face high temperature, strong convection, and shock waves generated by the explosion of explosives during the mission. . For the high temperature generated by the fire, most drones have adopted more...
