The working principle is as follows:
1. autonomous aerial inspection: a patrol path is set by the command center information platform 1, a patrol area is automatically changed according to the modified path, and maneuvering flight capability according to a given path in the air is provided through a rotor wing and a flight control system of the amphibious aircraft 3.
2. Aerial overlooking: through the double-light infrared thermal imaging sensor 12, the infrared and visible light pairs are combined to accurately find out the persons in distress on the shore and the persons in distress on the water surface.
3. Intervention on the personnel involved: by using an intelligent image detection and recognition algorithm (a convolutional neural network technology), the target of the teenager on the bank side is detected and found in real time in the air cruising process, and the early-warning is carried out through a built-in voice system to prevent the teenager from getting ill or getting out of the way. And if the user does not listen to the block, the related information is shared to the police department through the 4G network system.
4. Rescue drowning personnel: if the ship is in a drowned state, calling for help through a voice system and calling 110 and 120 through an information management platform to request police service and medical departments to intervene, the aircraft enters water for rescue at the same time, a target tracking system is started, the ship-borne rescue floating body is inflated after the ship-borne rescue floating body reaches a target in danger or drowned, the target is guided to hold the floating body or even a ship body through the voice system, life safety is guaranteed, if the ship-borne pull ring can be grasped and the ship body does not overturn, an underwater local path planning and navigation program is started, the aircraft drags the target to the shore, and if the ship-pull ring cannot be grasped or the ship body overturns (the probability is very low but the probability exists), buoyancy is enough to guarantee target safety, and further rescue is waited. After rescue is finished, if the aircraft runs normally, patrol is continued until patrol is finished or energy reaches a return requirement, and if the aircraft overturns, the aircraft is recovered and processed by a management department according to positioning information.
