Background technique

For a long time, due to the complexity of the geography of the disaster area, the complexity of the disaster situation in the disaster area, and the massive destruction of communications and transportation after the disaster, how to carry out the rescue in the disaster area is a big mountain before the rescuers. Rescue workers are often unable to communicate with the people in the disaster area, and cannot obtain first-hand disaster information; at the same time, due to the limitation of the number of rescuers, they cannot conduct search and rescue in a large area at the same time. At this time, drones have attracted the attention of rescuers due to their portability, lightness, simple operation, unrestricted by ground conditions, and wide inspection range. However, most of the functions of UAVs on the market currently focus on a certain point, more or less, there are problems such as lack of autonomy, lack of information collection modules, and fewer functions, which are not suitable for professional rescue activities. In disaster-stricken areas, cell phone communication base stations often fail to work. CN 107200145 A proposes a flood-fighting and disaster-relief method of unmanned aerial vehicle, which is realized by the following devices, including ground control station, unmanned aerial vehicle, GPS, camera, human body identification device, automatic decoupling device, hook cable and material box. The ground control station can control the operation of the unmanned aerial vehicle and receive information prompts from the unmanned aerial vehicle; the unmanned aerial vehicle includes a power system, a control system, a shaft support, and an intermediate platform; the GPS is located on the upper surface of the intermediate platform, and can Navigate for the drone and facilitate the ground control station to detect the position of the drone; the camera is located on the side of the intermediate platform; the human body recognizer processes the camera to take pictures to identify whether there are victims; the automatic decoupling The device can make the hook cable put down the material box; the hook cable is located in the direction of the vertical line of the middle platform, and is used to hook the material box; the material box is connected with a hook cable, and the material box contains life jackets, water and food, for the purpose of death provide a certain amount of life insurance. When there is a flood in some places, the ground control station controls the drone to search in a scattered manner, and the camera transmits the captured images to the human body identifier, which determines whether there are victims. When encountering victims, the ground control station will receive When prompted by the drone, the location of the drone can be quickly located through GPS, and the ground control station will send a rescue team to the rescue site quickly. Put on a life jacket, use water and food, replenish physical strength, and wait for the rescue team to arrive; when the rescue team rescues the victims, the drone returns to the ground control station to replenish supplies, and then goes to find the next victim. The existing technology is insufficient to make the human body recognizer meet the recognition standard, and communication is also a problem.
