FDMA-based unmanned aerial vehicle measurement and control cellular communication method

Abstract

The invention discloses an FDMA-based unmanned aerial vehicle measurement and control cellular communication method. The method comprises the following steps: establishing a hybrid base station; constructing a cellular communication network by using the hybrid base station; allocating a downlink frequency band, an uplink frequency band and a broadband frequency band to the cellular communication network; allocating a narrowband downlink frequency band and a narrowband uplink frequency band to each unmanned aerial vehicle; selecting a movable base station of the unmanned aerial vehicle from thehybrid base stations, and adjusting the direction of an antenna unit of the movable base station; sening notification information to the unmanned aerial vehicle, so that the direction of the unmannedaerial vehicle antenna unit is matched with the direction of the base station antenna unit of the movable base station by the movable base station; broadcasting a telemetry frame signal in a narrowband downlink frequency band by the unmanned aerial vehicle; receiving the telemetry frame signal and performing demodulation, decoding and frame format analysis by the movable base station to obtain atelemetry frame; and forwarding the telemetering frame by the movable base station to a main console. T through the FDMA technology, signal interference between unmanned aerial vehicles is avoided, multiple unmanned aerial vehicles can be accommodated, and the multiple access problem of an unmanned aerial vehicle measurement and control system is solved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle communication, and in particular relates to an FDMA-based unmanned aerial vehicle measurement and control cellular communication method. Background technique [0002] With the development of drone technology, drones are no longer simply used in film and television shooting, miniature selfies, etc., in agriculture, logistics, disaster relief, observing wild animals, monitoring infectious diseases, surveying and mapping, news reports, power inspections, etc. There are applications in various fields, and the problem of medium and long-distance UAV measurement and control has also attracted more and more attention. The UAV measurement and control system includes UAV telemetry, video downlink and UAV remote control. UAV measurement and control is an important means to track and locate UAVs, monitor the working status of UAVs, obtain video data and remotely control UAVs. Through UAV te...
