摘要
随着配网运维对无人机的广泛应用,针对山区等信号弱区域无人机失联及现有无人机黑匣子防丢定位器依赖手机移动通信网络等问题,本文提出一种无手机信号环境下的失联无人机追踪系统,包括定位追踪从机、中继机和主机。利用GPS/北斗定位失联无人机,通过LoRa无线模块传输信息给主机。若有障碍物,由携带中继机的无人机升空搭建三角通信链路,辅助搜寻人员找到失联无人机,为解决无人机失联问题提供新方案。
With the extensive use of unmanned aerial vehicles(UAVs)in distribution-network O&M,loss of contact in mountainous or weak-signal areas has become a critical issue.Existing black-box anti-loss devices relying on mobile communication networks are ineffective in such regions.This paper proposes a UAV tracking system that operates without cellular service,consisting of a positioning/tracking slave unit,relay UAV(s),and a ground master station.GPS/Beidou modules determine the lost UAV’s coordinates,and LoRa transceivers relay the data to the master station.If obstacles block the direct link,a relay UAV carrying a LoRa module is launched to establish a triangular communication path,assisting search personnel in locating the lost aircraft.The system offers a novel solution to UAV loss in no-signal environments.
