通信系统是无人机系统中最重要的组成部分之一,为了实现小型无人直升机稳定可靠的全自主飞行控制,设计并实现了基于WIFI并运用UDP协议和SOCKET通信机制的无人机系统实验数据链,在此基础上,基于无线射频模块和WIFI,实现了用于无人机运营阶段的远程飞行数据链;首先介绍无人机的通信系统框架,再对无人机实验数据链和远程飞行数据链的数据通信协议及软硬件实现进行详细说明;该通信系统有充裕的数据载荷,数据下传和上传延迟满足系统实时显示和控制要求,可在无人机平台上稳定可靠运行。
The communication system is one of the most important parts of UAV system.In order to achieve the stability and reliability of small UAV's autonomous flight control,design and implemnet an experimental communication system based on WIFI,which also with the help of UDP protocol and Socket.On this basis,also realize a data link based on WIFI and RF for remote flight in operational phase.After giving a brief introduction of the framework of UAV communication system,making a detailed description of data communication protocol and hardware and software for experimental communication system and remote flight communication system.With enough data payload and acceptable transmission delay for UAV monitoring and controlling,the Communication system for UAV platforms is reliable and stable.
