A kind of UAV and UAV search and rescue positioning method

Abstract

The present invention relates to the field of wireless communication technology, in particular to a UAV and a UAV search and rescue positioning method, the UAV includes: 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 To establish a connection with the ground terminal, and receive the signal sent by the ground terminal through multiple directional antennas in different directions, and then determine the signal strength. The main control processing module determines the corresponding movement of the UAV according to the signal strength vectors corresponding to the multiple directional antennas. Vector, and then determine the direction of movement and control the UAV to move according to the direction of movement. The UAV uses its own wireless signal detection module and directional antenna to detect the signal of the ground terminal carried by the searched and rescued person, automatically determine the direction of movement and fly, so that it can automatically adjust the flight route without manual control of the flight. Quickly determine the location of the person being searched and rescued, so it has fast search capability and higher search and 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 are also playing an increasingly important role. For example, in the application of UAVs in field search and rescue, high-altitude aerial photography observations are generally used to search for trapped people. However, this search method using aerial photography still relies on human eyes to be responsible for the search work of the target. Due to the physiological limitations of the human eye, when the environment is harsh such as dark, foggy, rainy and other poor visibility, or when there are many trees in the forest blocking the situation, the trapped people are often d...
