摘要
针对山区复杂环境下无人机巡线面临的多径干扰严重、受山体遮挡、信道环境变化快和大型无人机转场困难等问题,文章提出了采用中继通信的方式来保证无人机测控通信的可靠性,提高无人机的作业范围。首先讨论了无人机选型,并对固定中继、移动中继、空中中继和卫星中继等常用的无人机电力巡线中继方式进行设计与分析,比较各种中继方式的优缺点,对各种中继方式进行经济性分析,最后根据不同的应用场景给出最优中继方式推荐。
Aiming at the problems of UAV（Unmanned Aerial Vehicle, UAV） patrolling in complex mountainous area, such as obstruction of mountain, rapid change of channel environment and difficult transition of large UAVs, a relay communication method is proposed to ensure the UAV telemetry and control reliability. First, the UAV selection is discussed in this paper. Next the relay mode of UAVs power line patrolling including fixed relay, mobile relay, air relay and satellite relay are designed and analyzed. Then, the advantages and disadvantages of various relay methods are compared, and the economics of various relay modes are analyzed. Finally according to different scenarios, the optimal relay modes are recommended.
