Note that the air bottle 21 is provided inside the body 1. When the water sensor 22 detects water, it indicates that the unmanned aerial vehicle has landed on water, and then the main control board 8 controls the electromagnetic valve 23 to open, so that the air in the air inflation bottle 21 is input into the life buoy 24 through the air delivery pipe, and the life buoy 24 is full of air. In order to make the life buoy 24 sufficiently inflated, the electromagnetic valve 23 can be a flow electromagnetic valve 23, and a pressure gauge can be arranged on a gas transmission pipe to ensure the volume of input air.
After the personnel in the water seize the life buoy 24, the unmanned aerial vehicle navigates back to carry the personnel in the water to the ground by pressing the button switch 25.
As shown in fig. 1 to 5, an embodiment of the present invention further provides a rescue method of the above detection, positioning and lifesaving integrated unmanned aerial vehicle, including the following steps:
firstly, the unmanned aerial vehicle flies in the air through the propelling device 3, and the photoelectric pod 4 sends the acquired water area photos to a ground command center through the main control board 8. And the ground command center judges whether the person falling into water exists or not according to the water area photo.
In this embodiment, in the first step, the concrete steps of the ground command center determining whether there is a person falling into water according to the photograph of the water area include: when the ground command center judges the suspected person falling into the water, the flight height of the unmanned aerial vehicle is firstly reduced, and the photo of the suspected person falling into the water is obtained through the photoelectric pod 4. And the ground command center judges whether the person falling into water exists or not according to the photo of the suspected person falling into water.
It should be noted that, initially, the unmanned aerial vehicle performs a large-scale investigation with a high altitude, and then continuously sends the acquired water area photos to the ground command center through the main control board 8 by the photoelectric pod 4. The method can improve the investigation efficiency, and avoid the problem that the investigation efficiency is lower due to the fact that the height is consistent during investigation, the water area photos are too large in acquisition amount or the resolution ratio of the water area photos is limited, and the investigation efficiency is low
Step two, if the person falling into the water is found, calculating the coordinates of the person falling into the water through the main control board 8, wherein the coordinate calculation steps of the person falling into the water are as follows:
as shown in fig. 4, coordinates (x1, y1, z1) of the drone are obtained from the GPS module, where x1 is geographical latitude, y1 is geographical longitude, and z1 is elevation.
The distance L from the photoelectric gondola 4 to the person falling into the water is obtained by a laser range finder on the photoelectric gondola 4.
And acquiring an included angle alpha between a connecting line of the photoelectric pod 4 and a person falling into the water and the vertical direction through an angle sensor on the photoelectric pod 4.
The distance between the unmanned aerial vehicle and the person falling into the water in the vertical direction is h ═ L × cos α, so that the elevation z coordinate of the person falling into the water is z 1-h.
And (3) setting the projection of a connecting line of the unmanned aerial vehicle and the person falling into the water in the vertical direction as a projection line, wherein the length of the projection line is L × sina, and acquiring the included angle beta between the projection line and the meridian of the earth through an angle sensor on the photoelectric pod 4.
The distance between the unmanned aerial vehicle and the person falling into the water in the geographic latitudinal direction is L x sina x sin beta. The distance between the unmanned aerial vehicle and the person overboard is L plus sina plus cos beta in the geographic longitude direction.
Thus, the geographical latitude x coordinate of the man overboard is: x1-L sina sin beta. The geographical longitude y coordinate of the man overboard is: x1-L sina cos β.
And step three, the unmanned aerial vehicle is landed to the position near the personnel falling into the water according to the coordinates (x, y, z) of the personnel falling into the water. Falling to the vicinity of the man who falls into the water can prevent the propeller 5 from easily hitting the man who falls into the water.
And step four, automatically inflating after the inflatable life buoy 2 on the unmanned aerial vehicle detects falling into water. Unmanned aerial vehicle floats on the surface of water. Propulsion unit 3 truns into the low-speed operation, promotes unmanned aerial vehicle through propulsion unit 3 and goes on water to make unmanned aerial vehicle be close to the personnel of falling into water.
The water sensor 22 on the inflatable lifebuoy 2 can detect whether the unmanned aerial vehicle is floating on the water surface, at which point the fuselage 1 of the unmanned aerial vehicle is already fully located in the water. When the unmanned aerial vehicle is close to the person falling into the water, the high-definition camera on the photoelectric pod 4 can be used for navigation, the thrust difference can be achieved by controlling the rotating speed of the two propellers 5 or the rotor wings 6, and the unmanned aerial vehicle can be driven to the side of the person falling into the water under the correction of the staff.
And step five, after the unmanned aerial vehicle detects that the personnel falling into the water grasps the inflatable life buoy 2, the unmanned aerial vehicle conveys the personnel falling into the water to the shore.
The drone is triggered to know and return by the man falling into the water manually pressing the button switch 25. Still can send through long-range staff and control the instruction and make unmanned aerial vehicle return voyage.
In this embodiment, when unmanned aerial vehicle drove the personnel of falling into water and travel to the bank, unmanned aerial vehicle passed its real-time coordinate back ground command center.
The GPS module on the unmanned aerial vehicle transmits the real-time coordinate of the unmanned aerial vehicle back to the ground command center, so that the workers can acquire the positions of the unmanned aerial vehicle and the personnel falling into the water, and the rescue can be organized in time.
The unmanned aerial vehicle can focus detection, positioning and rescue on one unmanned aerial vehicle, and can find and position people falling into water in the shortest time. The high-efficiency and timely rescue is realized, and the lives of people are saved to the greatest extent.
The embodiments in the present specification are described in a progressive manner, and the same or similar parts among the embodiments may be referred to each other, and each embodiment focuses on the differences from the other embodiments. The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
