Abstract

The invention discloses an FDMA-based UAV measurement and control cellular communication method, comprising: building a hybrid base station; using the hybrid base station to construct a cellular communication network; allocating a downlink frequency band, an uplink frequency band and a broadband frequency band for the cellular communication network; The man-machine allocates a narrow-band downlink frequency band and a narrow-band uplink frequency band; select the active base station of the drone from the mixed base stations, and adjust the direction of the antenna unit of the active base station; the active base station sends notification information to the drone to make the direction of the antenna unit of the drone Match the direction of the base station antenna unit of the active base station; the UAV broadcasts the telemetry frame signal in the narrowband downlink frequency band; the active base station receives the telemetry frame signal for demodulation, decoding and frame format analysis to obtain the telemetry frame; the active base station forwards the telemetry frame to Main console; the present invention avoids signal interference between drones through FDMA technology, can accommodate multiple drones, and solves the problem of multiple access of the drone measurement and control system.

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...
