Embodiment Construction
[0039] The present invention is described in further detail below in conjunction with accompanying drawing:
[0040] Such as figure 1 As shown, the present invention first establishes wireless coverage facilities in offshore wind farms. Because offshore wind farms are far away from the coast, ordinary public base stations cannot cover offshore wind farms, so each offshore wind farm will build an independent ring network to connect each wind turbine to the booster station, such as figure 2 As shown, the separate fan ring network is only used to transmit fan signals, and inspection drones cannot be connected to it. For the scenario where UAVs fly in wind farms, deploy AP devices outside the wind turbines, physically label each AP, and connect to the wind farm ring network through switches to complete the coverage of offshore wind farms.
[0041] During the inspection process of the UAV in the wind farm, the AP serving the UAV will continue to change, so in the process of chan...

The invention discloses an unmanned aerial vehicle communication switching method, system and device and a storage medium. The method comprises the steps: S1, determining a switching parameter according to the position and speed of an unmanned aerial vehicle; S2, adjusting the switching parameter by using a nonlinear index DPSO algorithm; S3, judging whether the adjusted switching parameter meets the QoE of video transmission of the unmanned aerial vehicle or not: if not, executing the step S2, and if yes, taking the adjusted switching parameter as a current communication switching parameter of the unmanned aerial vehicle and as an initial value of a next nonlinear index DPSO algorithm. The video transmission QoE index is met, the video transmission efficiency during unmanned aerial vehicle inspection is improved, and the unmanned aerial vehicle inspection efficiency is improved.
Description
technical field [0001] The invention belongs to the field of wireless communication, and relates to a communication switching method, system, equipment and storage medium of an unmanned aerial vehicle. Background technique [0002] Offshore wind farms have a wide range and complex environment, making it difficult to access and choose transportation equipment, which greatly hinders the maintenance of operation and maintenance personnel. At present, operation and maintenance personnel often use drone inspections and other methods to conduct operation and maintenance inspections of wind turbines. UAVs have high requirements for communication bandwidth when performing video inspections. Due to the large distance between wind farms and the long distances traveled by UAVs during inspections, communication links must be switched when UAVs communicate. In the traditional communication switching process, the quality of UAV video communication cannot be guaranteed, resulting in a dec...
