无人机遥感组网冗余容错的研究

Redundancy and fault tolerance of unmanned aerial vehicle remote sensing network

针对无人机在遥感遥测领域组网过程中存在的随机故障,进而导致无人机在任务执行过程中任一约束的及时响应缺失,将会影响任务总体结果或导致整个任务部分及完全失败的问题,论文提出无人机遥感组网冗余容错方法。该方法采用领航—跟随的无人机编队飞行模式,多台组网无人机稳定可靠完成指定的飞行任务,验证了冗余容错方法,解决了无人机遥感组网冗余容错技术中的有和无的问题。

The random failure of the unmanned aerial vehicles(UAVs)in performing the task of remote sensing will result in the lack of timely response in the mission execution process,affecting the overall result of the mission or causing partial or complete failure of a mission.To address the failure issues,a redundant and faulttolerant method for UAV remote sensing networking were proposed.With this method,the lead-follower drone group flight mode is used.Multiple networked drones can complete the designated flight tasks stably and reliably.The simulation result verifies the efficacy of the redundant fault-tolerant method,which can help solve the problem of missing data or task failure in the remote sensing of UAV.
