中继系统在无人机电力巡视中的应用

Application of Relay System in Unmanned Aerial Vehicle Power Patrol

随着无人机技术的飞速发展,各种类型的无人机在电力线路巡视中的应用越来越多,但目前无人机在超视距飞行方面存在颈项。输电线路大多分布在崇山峻岭之间,无人机作为在电力系统巡线中的一个重要应用,传统的"点对点"通信模式无法满足无人直升机在巡线时的通信要求。重点分析了目前主要的中继方式结构及其特点,重点就其应用对象特性进行了分析,以方便根据不同的应用场合选择最佳的中继方式。

With the rapid development of unmanned aerial vehicle （UAV） technology, various types of UAV have be widely applied in the electric power line patrol, but there exists a bottleneck in drone over-the-horizon flight. Because transmission lines are mostly distributed among the high mountains, the traditional ＂point to point＂ communication mode cannot meet the communication requirements of UAV in power system patrol. This paper analyzes the structure and characteristics of the main relay modes, emphatically the application subject properties, providing reference for choosing the best relay mode according to different application conditions.
