Embodiment Construction

[0059] This embodiment provides a DA-TDMA-based UAV measurement and control cellular communication method, such as Figure 4 shown, including the following steps:

[0060] S101, building M hybrid base stations B 0 , B 1 , B 2 ,...,B M-1 , and each hybrid base station is equipped with a base station antenna unit, and each UAV is equipped with a UAV antenna unit to realize communication between the hybrid base station and the UAV. The hybrid base station and the main control station can pass through any link Road communication, such as the use of relay satellites, 3G / 4G / 5G networks or optical fibers, to solve the communication between the UAV and the main console. Both the base station antenna unit and the UAV antenna unit include an omnidirectional antenna and a MIMO antenna, the omnidirectional antenna is used for transmitting telemetry and remote control data, and the MIMO antenna is used for transmitting video stream data. Each UAV and hybrid base station is equipped wi...

Abstract

The invention discloses a DA‑TDMA-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 narrowband frequency band and a broadband frequency band for the cellular communication network; Routing time slots and uplink routing time slots; hybrid base stations obtain downlink routing time slots and uplink routing time slots; in the downlink routing time slot stage, select active base stations for UAVs; in the uplink and downlink routing protection time slot stage, unmanned The UAV dynamically allocates the available time slice; in the uplink routing time slot phase, the UAV adjusts the direction of its own UAV antenna unit; in the telemetry time slice, the UAV broadcasts the telemetry frame signal; forwarded to the console. The invention uses time division multiple access technology to distinguish different drones by using different time slots and time slices, avoids interference between signals of each drone, and solves the problem of multiple access 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 a DA-TDMA-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. [0003] 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. Thr...
