Unmanned aerial vehicle and search and rescue positioning method for unmanned aerial vehicle

Abstract

The invention relates to the technical field of wireless communication, in particular to an unmanned aerial vehicle and a search and rescue positioning method for the unmanned aerial vehicle. The unmanned aerial vehicle comprises a wireless signal detection module, a main control processing module and a plurality of directional antennas, wherein the wireless signal detection module can be used for building connection with a ground terminal and receiving signals sent by the ground terminal through the multiple directional antennas in the different directions, and accordingly the intensity of the signals is determined; the main control processing module determines the motion vector corresponding to the unmanned aerial vehicle according to the signal intensity vector corresponding to the multiple directional antennas, accordingly, the motion direction is determined, and the unmanned aerial vehicle is controlled to move in the motion direction. The unmanned aerial vehicle can detect a signal of a ground terminal carried on a searched and rescued person, automatically determine the moving direction and fly through the self-contained wireless signal detection module and the self-contained directional antennas, thus, the unmanned aerial vehicle can automatically adjust the flight path and quickly determine the position of the searched and rescued person without being controlled to fly manually, and the unmanned aerial vehicle has quick search capacity and higher rescue efficiency.

Description

Technical field [0001] The invention relates to the technical field of wireless communication, in particular to an unmanned aerial vehicle and an unmanned aerial vehicle search and rescue positioning method. Background technique [0002] In recent years, the rapid development of drone technology has made it more and more widely used in various fields. Especially in the field of earthquake relief, drones have also played an increasingly important role. For example, in the field of search and rescue applications, UAVs generally use high-altitude aerial observations to search for trapped persons. But this search method using aerial aerial photography still relies on the human eye to be responsible for the search for the target. Due to the physical limitations of the human eye, when the environment is bad, such as dark, heavy fog, rain and other poor visibility, or when there are more trees in the forest, the trapped people are often difficult to be found. Increase the difficulty o...
