Child drowning prevention monitoring method and system based on unmanned aerial vehicle and unmanned aerial vehicle

Abstract

The invention discloses a child drowning prevention monitoring method and system based on an unmanned aerial vehicle and the unmanned aerial vehicle. The monitoring method comprises an early warning stage and a rescue stage. The early warning stage comprises the steps that the server informs the unmanned aerial vehicle of arriving at a target position according to the battery endurance state of the nearby unmanned aerial vehicle and the distance from a monitoring site; the unmanned aerial vehicle plans an event shortest path to reach a target position according to the map information and the current wind direction information; the monitored real-time video is uploaded to a server at the target position, and the real-time video is sent to a guardian terminal by the server; the rescue stagecomprises the steps that if a human body enters water, the unmanned aerial vehicle uploads video information of the human body entering water to a server in real time, the server carries out behavioranalysis on the video information, and if it is judged that the human body is drowning, the server remotely commands the unmanned aerial vehicle to implement rescue; the unmanned aerial vehicle reaches the human body position and releases the rescue device. The invention further comprises a child drowning prevention monitoring system based on the unmanned aerial vehicle and the unmanned aerial vehicle. The method system have the advantages of high rescue efficiency, high rescue speed and the like.

Description

technical field [0001] The present invention relates to the technical field of intelligent rescue, in particular to a drone-based child drowning prevention monitoring method, system and drone. Background technique [0002] Outdoor drowning accidents often occur. Due to limited conditions, in many cases, the drowning person cannot be rescued in time because the drowning person is too far away from the shore, or there is no person on the shore who can provide rescue, resulting in danger. [0003] In 2016, the patent with the application number [2016112684434] designed a drone rescue equipment that can be used for rescue. The equipment includes a wearable monitoring and rescue terminal and a drone monitoring terminal. The patent specifically designed a wearable The structure of the equipment, after the human body drowns, on the one hand, the wearable device broadcasts the location information to the lifeguard and releases the airbag at the same time; Among them, it supports co...

Problems solved by technology

[0007] However, the above-mentioned patented technologies have the following defects: (1) the existing anti-drowning system of the UAV that can implement direct rescue lacks autonomy, and requires human manipulation to achieve positioning return and rescue; (2) some UAVs only monitor (Manual remote control monitoring, online self-identification monitoring) drowning behavior, and broadcast the location and real-time environment to relevant personnel for help, instead of directly implementing rescue such as lowering the lifebuoy or life-saving rope; (3) some patents that can directly implement rescue, It does not take into account the fact that the drowning person has sunk into the water and cannot touch the surface rescue tools (such as lifesaving ropes and lifebuoys); (4) The rescue route of the drone is not optimally planned, which is easy to delay the rescue time; (5) currently It is generally judged whether drowning is based on the video of the water surface, and the drowning person on the water surface is searched by flying in the air, without considering that the drowning person may have sunk into the water. In this case, it is impossible to determine the location of the drowning person only by searching the water surface in the air
