为了提高输电线路巡检无人机群的动态调度能力,提出基于通信连通性的输电线路巡检无人机群动态调度方法。融合输电线路巡检无人机调度参数,构建通信信道均衡模型,采用网格分块区域规划方法进行无人机动态调度的参数寻优与路径规划。建立输电线路巡检无人机群飞行空间的三维空间规划模型,采用模糊状态寻优控制方法进行无人机群路径规划和调度的参数识别和路径寻优,构建输电线路巡检无人机群调度的通信连通性参数分析模型。通过自适应寻优算法,结合码间干扰抑制方法进行调度过程中的抗干扰设计和通信连通性设计,实现输电线路巡检无人机群智能调度。仿真结果表明,方法对输电线路巡检无人机群动态调度结果准确性较高,误码率最低为3.3%,抗干扰能力较强。

In order to improve the dynamic dispatching ability of drone clusters in transmission line patrol,a dynamic dispatching method based on communication connectivity was proposed.A communication channel equalization model was constructed by integrating the dispatching parameters of drones for transmission line patrol inspection.The parameter optimization and path planning for drone dynamic dispatching were carried out by using the grid block area planning method.A three-dimensional spatial planning model of drone cluster flight space for transmission line patrol was established,and a fuzzy state optimization control method was used for parameter identification and path optimization of drone cluster path planning and dispatching,and a communication connectivity parameter analysis model for drone cluster dispatching in transmission line patrol was built up.The adaptive optimization algorithm and the inter-symbol interference suppression method were used to design the anti-interference and communication connectivity in the dispatching process,so as to realize the intelligent dispatching of drone clusters in transmission line patrol.The simulation results show that the accuracy of the proposed method for dynamic dispatching of drone clusters is high,the bit error rate is at least 3.3%,and the anti-interference ability is strong.
