基于中心节点的无人机集群通信架构设计及验证

Design and Verification of UAV-based Cluster Communication Architecture Based on Central Node

传统无人机集群通信架构受地面基站的限制影响,抗干扰能力较弱,同时通信方式不灵活也使其自主协同能力较差。为了应对在动态不确定性环境下执行任务的能力,摆脱地面基站对无人机集群的限制,提出一种基于中心节点控制的无人机集群通信架构模式。该通信架构模式总体为一种多级分层结构,基于中心节点负责集群成员调度和任务发布的特性,避免了传统GSC模式远距离发布指令带来的集群分布式决策能力较弱的问题。采用图形化模型检测工具ISPIN对上述通信架构的可靠性进行了验证。验证结果表明,该通信架构采用动态调整布局,提高了通信性能,降低了对地面基站的依赖,整体提高了无人机集群协同作战的抗干扰能力及协同执行效率。

The traditional unmanned aerial vehicle(UAV)cluster communication architecture is limited by the ground base station,resulting in weak anti-interference ability.At the same time,the inflexible communication mode also makes its autonomous coordination ability poor.In order to cope with the ability of executing tasks in dynamic uncertain environment and get rid of the restriction of ground base station on UAV cluster,a communication architecture mode of UAV cluster based on central node control is proposed.The communication architecture mode is a multi-level hierarchical structure based on the characteristics of the central node responsible for cluster member scheduling and task release and it avoids the problem of weak distributed decision making ability of the cluster caused by the traditional GSC mode.The reliability of the communication architecture is verified using the graphical model detection tool ISPIN.The verification results show that the communication architecture adopts dynamic adjustment layout,which improves the communication performance,reduces the dependence on the ground base station,and improves the anti-interference ability and collaborative execution efficiency of the UAV cluster cooperative combat as a whole.
