基于北斗短报文通信的无人机安控系统

UAV Safety Control System Based on Beidou Short-message Communication

针对某大型无人机现有安控系统的不足,利用北斗短报文通信技术研制了地面北斗便携站和机载BD安控器,实现了北斗短报文指令被动安控功能和安控区域自判断主动安控功能;采用独立的单片机板卡作为笔记本电脑故障的应急备份,实现了一键发送安控指令功能,提高了指令发送的可靠性;采用多个地面北斗便携站同时工作的方式可有效提高短报文指令发送频度。经实际使用验证,其工作正常,运行可靠。验证结果表明,该无人机安控系统设计合理可行,可推广应用于其他无人机安控系统。

To overcome the shortcomings of the existing safety control system of a large Unmanned Aerial Vehicle（ UAV）,we designed a portable Beidou ground station and an airborne BD safety controller by using Beidou short-message communication technology,which realized the passive safety control of Beidou shortmessage instructions and the self-judgment based active safety control of the safety control region. An independent MCU board was used as emergency backup device when the laptop failed,which could send control instructions by pressing a button and improve the reliability of instruction transmission. The mode of multiple portable Beidou ground stations working at the same time could effectively increase the frequentness of short-message sending. It is proved by practical application that its operation is smooth and reliable. The results show that the design of the UAV safety control system is reasonable and feasible,which can be applied to other UAV safety control systems.
