Problems solved by technology

However, the existing UAV airborne fire extinguishing bomb launching devices are all fixedly connected to the UAV, and the launching device cannot isolate the disturbance caused by the UAV attitude, so the fire extinguishing bomb can only be launched in the hovering state, and there is no Fire control calculations can only be used to launch fire extinguishing bombs at a relatively short distance. There is no guarantee of the accuracy of the fire extinguishing bombs, the hit rate is low, and it is impossible to accurately aim and launch moving targets; at the same time, the launch of fire extinguishing bombs is mostly controlled manually. Launch mode, less intelligent

Embodiment 1

[0029] like figure 1 As shown, the UAV airborne fire extinguishing bomb device in the present invention includes: N-mounted launcher unit 1 (such as triple-mounted launcher unit 1), which is mounted on the drone body 100, and the N-mounted The launcher unit 1 contains at least one fire extinguishing bomb, and N is a positive integer; the three-axis servo stabilization unit 2 is connected to the N-mounted launcher unit 1, and is used to isolate the attitude disturbance when the body is flying or hovering, ensuring The stability of the N-mounted launcher unit 1 in the inertial space; the fire control unit 3, which generates the coordinates of the impact point of the fire-extinguishing projectile under the current flight attitude condition in real time through the received fire control information, and sets the launch gate at the same time. When the bomb point falls into the launch wave gate, the fire extinguishing bomb automatic launch signal is generated according to the set la...

Embodiment 2

[0035] This embodiment improves a kind of fire-fighting unmanned aerial vehicle (preferably fire-fighting unmanned helicopter), such as Figure 3-4 As shown, it includes: a drone body 100, and the drone body 100 is equipped with a flight control system, a power system, an electrical system, a transmission system, a communication system, etc., to complete the autonomy or Manually controlled flight; the UAV airborne fire extinguishing bomb device 200 described in Embodiment 1, which is connected to the UAV body 100; the flight control unit 6, which is used to obtain environmental information, and control according to the environmental information The flight attitude and / or trajectory of the drone body 100 in the air, in this embodiment, as Figure 5 As shown, the flight control unit 6 includes: an obstacle avoidance sensor 61, which includes one or more of a visual obstacle avoidance sensor, a radar obstacle avoidance sensor, and a sonar obstacle avoidance sensor, for obtaining ...

Embodiment 3

[0044] This embodiment also provides the emission control method described in Embodiment 1, which is characterized in that it includes the following steps:

[0045] S1. Install an N-mounted launcher unit, a three-axis servo stabilization unit, a fire control unit, a fire extinguishing bomb launch controller, and a photoelectric pod on the drone body, and carry out the pod optical axis and fire extinguishing bomb when leaving the factory. The electrical zero position calibration of the bomb shaft makes the included angle between the bomb shaft of the fire extinguishing bomb and the optical axis of the photoelectric pod be 0-0.1°;

[0046] After the UAV is lifted into the air, the image information and / or audio information of the fire scene and / or the distance information from the fire scene can be obtained in real time through the photoelectric pod, and the automatic image tracking of the fire point of the fire scene and the flight or hovering of the UAV body can be carried out....

Abstract

The invention discloses an airborne fire-extinguishing bomb device for an unmanned aerial vehicle, a fire-fighting unmanned aerial vehicle, and a launching control method. The airborne fire-extinguishing bomb device for the unmanned aerial vehicle comprises an N-linked launching canister unit, a three-axis servo stabilization unit, a fire control unit, and a fire-extinguishing bomb launching controller, wherein the N-linked launching canister unit is mounted on an unmanned aerial vehicle body; the three-axis servo stabilization unit is used for isolating attitude disturbance during the flightor hovering of the unmanned aerial vehicle body, so that the stability of the N-linked launching canister unit is ensured; the fire control unit generates the coordinates of impact points of fire-extinguishing bombs under a current flight attitude condition, meanwhile, a launching wave gate is arranged, and when the impact points fall into the launching wave gate, automatic launching signals for the fire-extinguishing bombs are generated according to a set launching sequence; and the fire-extinguishing bomb launching controller is used for generating fire-extinguishing bomb ignition launchingaction according to the automatic launching signals for the fire-extinguishing bombs, so that launching for the fire-extinguishing bombs is realized. According to the airborne fire-extinguishing bombdevice for the unmanned aerial vehicle, the fire-fighting unmanned aerial vehicle, and the launching control method, the disturbance is isolated through the three-axis servo stabilization unit, so that the aiming and firing accuracy, and the intelligent degree are increased.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle-mounted fire extinguishing bomb device, a fire-fighting unmanned aerial vehicle and a launch control method. Background technique [0002] UAVs are now widely used in the field of firefighting. UAVs carry fire extinguishing bombs filled with fire extinguishing agents, and are fired at the fire source through the sighting device to complete the fire extinguishing task. However, the existing UAV airborne fire extinguishing bomb launching devices are all fixedly connected to the UAV, and the launching device cannot isolate the disturbance caused by the UAV attitude, so the fire extinguishing bomb can only be launched in the hovering state, and there is no Fire control calculations can only be used to launch fire extinguishing bombs at a relatively short distance. There is no guarantee of the accuracy of the fire extinguishing bombs, the hit rate is ...
