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

The present application provides a U2X communication mode selection and trajectory design method, device, equipment and storage medium of a cellular UAV, which relate to the field of UAV sensing technology. This application mainly proposes the MIMO mode and the relay mode, and determines the distance between the data collected by the UAV and the data transmitted according to the preset data transmission index, and then calculates the multiple data in the cellular network based on the specific data collection task received. The time it takes for UAVs to transmit data in MIMO mode or relay mode is used as a cooperation mode for multiple UAVs to complete the current data collection task in a less time-consuming cooperation mode, and the UAVs are planned in this cooperation mode. The flight trajectory, through the U2X communication of the UAV, enables multiple UAVs in the cellular network to cooperate to complete the task of collecting and transmitting the data of the ground sensor to the base station, so as to ensure the quality of communication services and reduce the effect of transmission delay.
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...
