[0004] Moreover, the current trajectory design scheme for cellular network-connected drones mainly focuses on the trajectory design problem in the scenario of communication between the drone and the base station and the scenario of communication between drones. In the actual drone system, there is no The data sensed by the human-machine needs to be directly transmitted to the mobile device, but the current trajectory design scheme for the cellular network-connected UAV lacks the direct communication (that is, U2D: UAV-to-Device, the communication between the UAV and the mobile device) ) scenario, which makes the existing schemes unsuitable for the trajectory design problem in this scenario

The embodiment of the invention relates to the technical field of unmanned aerial vehicle area monitoring, in particular to a cellular network connected unmanned aerial vehicle trajectory design and interference management method and device. The method is applied to two or more unmanned aerial vehicles, each unmanned aerial vehicle synchronously executes a task in a periodic form, each period comprises a plurality of frames, and the method comprises the steps that each unmanned aerial vehicle performs intensive training on a track algorithm of the unmanned aerial vehicle; the base station broadcasts all initial information to each unmanned aerial vehicle; in each frame, each unmanned aerial vehicle obtains the current states of all the unmanned aerial vehicles through the base station; when each period starts, the unmanned aerial vehicle calculates a sensing point and a transmission point in the period where the unmanned aerial vehicle is located through a trajectory algorithm according to the latest states of all the other unmanned aerial vehicles; and the unmanned aerial vehicle directly flies to the sensing point for data acquisition and then directly flies to the transmission point for data transmission. According to the invention, a plurality of unmanned aerial vehicles are allowed to work synchronously, the integrity is stronger, and the timeliness is higher; and the mutual interference is alleviated.
Description
technical field [0001] The embodiment of the present application relates to the technical field of UAV area monitoring, and in particular, relates to a method, device, storage medium and equipment for trajectory design and interference management of a cellular networked UAV. Background technique [0002] Drones are powerful IoT-aware devices that can be widely used in various fields such as industry, agriculture, commerce, and military. In existing UAV systems, UAVs transmit sensing data to mobile devices through unlicensed frequency bands (such as: ISM frequency bands). Due to the random access characteristics of unlicensed spectrum, drones will be subject to uncontrollable interference, so the service quality of perception services is difficult to guarantee. In order to solve this problem, an effective solution is to provide support for UAV perception services through terrestrial cellular networks, which is also known as cellular network-connected UAVs. [0003] In some ...
