Abstract

In order to ensure the long-distance, low-delay and high-rate reliable transmission of civil UAV video signals and control signals, and solve practical application problems, this paper studies and designs a real-time transmission system for UAV video signals and control signals based on 5G network. The onboard computer uses Nvidia Jetson Nano, and the 5G module uses Huawei MH5000 module. In addition, the H.265 encoding method is improved for the characteristics of UAV video, and the MAVLink protocol is used as the control signal transmission protocol. The system has the characteristics of wide application range, high reliability and low delay. At the same time, a physical platform was set up to conduct experiments. After a large number of repeated experiments, the end-to-end transmission delay of the video signal was measured to be 1.2s, the transmission rate was 97Mb/s, and the control signal response delay was 30ms. This performance fully meets the application requirements of civilian UAVs.

基于5G网络的无人机视频与控制信号实时传输系统设计

为了保证民用无人机视频信号和控制信号的远距离、低时延、高速率可靠传输，解决实际应用问题，本文研究设计了一种基于5G网络的无人机视频信号和控制信号实时传输系统。板载机采用英伟达Jetson Nano, 5G模块采用华为MH5000模块。此外，针对无人机视频的特点，改进了H.265编码方法，采用MAVLink协议作为控制信号传输协议。该系统具有适用范围广、可靠性高、时延低等特点。同时搭建物理平台进行实验。经过大量重复实验，测得视频信号端到端传输延迟为1.2s，传输速率为97Mb/s，控制信号响应延迟为30ms。该性能完全满足民用无人机的应用需求。
