Embodiment Construction

[0045] The present embodiment provides a TS-ALOHA-based UAV measurement and control cellular communication method, comprising the following steps:

[0046] S1, build 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 with a positioning and t...

Abstract

The invention discloses a TS-ALOHA-based method for measuring and controlling cellular communication of unmanned aerial vehicles, comprising the following steps: building a hybrid base station, each unmanned aerial vehicle and the hybrid base station are provided with a positioning and timing module; using the hybrid base station to construct a cellular communication network; Allocate a narrow-band frequency band and a broadband frequency band for the cellular communication network; the UAV sends a downlink routing frame, and selects the active base station of the UAV from the mixed base stations; the active base station sends notification information to the UAV, so that the direction of the antenna unit of the UAV Match the direction of the antenna unit of the base station; the drone uses the TS‑ALOHA protocol to broadcast the telemetry frame signal on the narrowband frequency band; the active base station receives the telemetry frame signal and forwards the parsed telemetry frame to the main control station. The invention enables multiple UAVs and hybrid base stations to transmit information in the same frequency band through the time slot-ALOHA protocol, relatively reduces the collision probability of data frames, and solves the problem of multiple access of the UAV 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 TS-ALOHA-based measurement and control cellular communication method for unmanned aerial vehicles. 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...
