Problems solved by technology

Need to consume a lot of manpower and material resources
In the communication relay process of the drone group, what kind of relationship should be between multiple drones, and how can multiple drones cooperate with each other and automatically elect relay forwarding points? And in the process of selecting the communication relay point, will there be no oscillation phenomenon of the movement of the drone? These problems are not mentioned in prior art solutions

Embodiment

[0020] This embodiment provides a schematic diagram of constructing a UAV relay topology as follows: figure 2 shown. figure 2 Among them, S is the source point to be relayed, and D is the destination point. The occlusion between S and D does not exceed 100 meters. At this point, the lift-off height of all drones can be set to 100 meters. This avoids all occluders. First, all UAVs obtain the source point S and destination D and related coordinates and height information through the control station or through configuration before taking off (execute T101). UAV No. 1 takes off, and when it reaches an altitude of 100 meters, it will first fly towards point S according to the coordinate information. After arriving at point S, he then flies in the direction of SD towards the coordinates of point D, and the altitude remains unchanged. Measure the transmitted signal and wireless signal strength RSSI value of point S every certain distance m (execute T102). The communication di...

Abstract

The invention provides an unmanned aerial vehicle topology generation method for communication relay. A first unmanned aerial vehicle flies between a source point S and a destination point to find a relay point position after starting from the source point S, if the first unmanned aerial vehicle can establish the communication relay for the source point S and the destination point D, the generation of the relay topology is finished; if the first unmanned aerial vehicle cannot establish the communication relay for the source point S and the destination point D, the first unmanned aerial vehicle firstly establishes the direct communication with the source point S, and then a second unmanned aerial vehicle starts from the source point S and flies between the first unmanned aerial vehicle and the destination point D to find the relay point position until a plurality of unmanned aerial vehicles are used as the relay nodes to establish a communication link. The method disclosed by the invention is free from the artificial intervention, the problem that the communication link is intermittent and repeated in oscillatory movement is avoided.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for generating topology of an unmanned aerial vehicle for communication relay. Background technique [0002] Multi-UAV communication relay is one of the important application scenarios of current UAV swarms. Communication relay is to solve the problem that the two parties cannot communicate directly due to the existence of occlusion distance between two points. If the UAV is used to transfer in the air, it can realize communication between two points across the line of sight. But how to choose these relay points? Especially when there are multiple drones, multiple drones need to cooperate with each other to form a relay topology composed of drones, and how to control and coordinate these drones when a group of drones are used for communication relay , how to make them cooperate to form a fast and accurate communication relay link. It is an urgent pr...
