A relay network deployment method and a device

Abstract

The invention discloses a relay network deployment method and a device, which relate to the technical field of unmanned aerial vehicle communication. The invention is used for solving the problem thateach unmanned aerial vehicle can not communicate normally in large-scale application due to the communication broadband limitation in the prior art. The method comprises the following steps: when thecontrol center is not located within the communication radius of the unmanned aerial vehicle, and / or the control center is unable to meet the requirement of the communication bandwidth of the unmanned aerial vehicle for executing the task, determining that the unmanned aerial vehicle and the control center are not communicable; determining a relay node located within the communication radius of the unmanned aerial vehicle and satisfying the relay condition as a first relay node of the unmanned aerial vehicle, wherein the relay condition is that the communication bandwidth of the UAV is smaller than the minimum available bandwidth of the relay node, and the number of relay nodes on the link of the UAV to the control center is larger than the number of relay nodes on the link of the relay node to the control center; updating the remaining communication bandwidth available to the first relay node and the control center according to the communication bandwidth of the unmanned aerial vehicle.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicle communication, and more specifically relates to a relay network deployment method and device. Background technique [0002] With the emergence and development of unmanned aerial vehicles, since the last century, unmanned aerial vehicles have been gradually applied to the military field, serving as target drones, performing tasks such as reconnaissance and fixed-point bombing. Entering the 21st century, especially in the past ten years, with the miniaturization of UAVs, the emergence of rotor UAVs, and the investment of domestic and foreign scientific research institutions and technology companies, more and more UAV applications are changing to the civilian field. UAVs are gradually being more and more widely used in police, urban management, agriculture, geology, meteorology, electricity, emergency rescue, video shooting and other fields. In the field of UAV technology, UA...
