Application of Patrol Against Mountain Fire in Transmission Channels Based on UAV Relaying Cooperative Technology

针对现有输电通道防山火巡视监测方法时效性差、精度低、可视化不足等问题,结合无人机高效、灵活等特点,提出一种基于两架无人机中继协同作业开展输电线路通道山火巡视的方法。无人机协同巡查模式可通过中继技术维持无人机数据链路,实时回传无人机采集的视频数据,便于第一时间开展防灾决策部署,解决输电通道复杂地形遮挡数据链路信号、火势实时监测等难题。实践结果表明:于山火高发期针对重要输电通道开展高频次无人机中继协同防山火巡视作业,在发现初期山火隐患方面效果显著,为输电通道差异化防山火巡视提供了新的技术手段。

In view of poor timeliness,low accuracy and insufficient visualization of existing methods of mountain fire prevention inspection and monitoring in transmission channels,the paper proposes a method based on relaying cooperative operation of two UAVs to carry out mountain fire inspection in transmission channels in combination with the characteristics of UAVs such as high efficiency and flexibility.The cooperative inspection mode of UAV can maintain the UAV data link through relaying technology and transmit back the video data collected by the UAV in real time,which facilitates to timely carry out disaster prevention decision and deployment and solves the problems of complex terrain-blocked data link signal and real-time monitoring of fire in transmission channels.The practical results show that the high-frequency UAV relaying cooperative fire prevention inspection operation for important transmission channels during the period of a high incidence of mountain fires is effective in discovering the fire hazards at the initial stage and provides a new technical means for the differentiated fire prevention inspection of transmission channels.
