Cellular unmanned aerial vehicle U2X communication mode selection and trajectory design method and device

Abstract

The invention provides a cellular unmanned aerial vehicle U2X communication mode selection and trajectory design method and device, equipment and a storage medium, and relates to the technical field of unmanned aerial vehicle sensing. According to the invention, an MIMO mode and a relay mode are provided; the distance between collection data and transmission data of an unmanned aerial vehicle is determined according to a preset data transmission index; further, a received specific data acquisition task is used as a basis, time consumed by a plurality of unmanned aerial vehicles in the cellularnetwork for transmitting data in an MIMO mode or a relay mode is calculated; a cooperation mode consuming less time is used as a cooperation mode for multiple unmanned aerial vehicles to complete thecurrent data acquisition task, a flight path of the unmanned aerial vehicles is planned in the cooperation mode, and through U2X communication of the unmanned aerial vehicle, a plurality of unmannedaerial vehicles in the cellular network cooperate to complete the task of collecting data of a ground sensor and transmitting the data to a base station. Thus, the effect of reducing transmission delay is achieved while the communication service quality is guaranteed.

Description

technical field [0001] The present application relates to the field of drone sensing technology, in particular to a cellular drone U2X communication mode selection and trajectory design method, device, equipment and storage medium. Background technique [0002] With the development of science and technology, in the fields of atmospheric environment monitoring and address survey, it is more and more applied to UAV sensing tasks. In the UAV sensing task, the ground sensor is responsible for collecting data such as temperature, air quality, and pictures, and the UAV is responsible for transmitting the data collected by the ground sensor to the base station for data processing. [0003] Under the prior art, a single UAV is generally used to complete the entire task of transmitting data collected by ground sensors to the base station. When the ground sensor is far away from the base station, it is difficult for a single UAV to communicate with the base station to ensure high tra...

AI Technical Summary

Problems solved by technology

When the ground sensor is far away from the base station, it is difficult for a single UAV to communicate with the base station to ensure high transmission QoS and low communication delay at the same time

[0004] Moreover, when multiple drones are set up in the network, multiple drones will perform the same part of the task of transmitting the data collected by ground sensors to the base station, resulting in duplication of data transmitted by multiple drones, thereby wasting time in the network. limited transmission resources
