摘要
针对目前输电线路巡检中无人机只能在视距范围飞行的问题,按照电力巡线对数据传输的要求,提出了利用无人机中继拓展通信覆盖范围的方法;分析了带均衡的空间分集接收技术、低密度奇偶校验码(LDPC)编码技术等关键技术,设计了无人机通信中继系统方案;最后给出了该方案的通信中继效能分析.效能分析结果表明,该方案能有效解决无人机超视距巡检信息传输中的传输距离和可靠性问题,对无人机在电力系统的推广应用具有重要价值.
In view of the problem that the UAV could only fly in the horizon range for the current lineinspection of the power transmission, according to the requirement for the data transmission of power lineinspection, this paper proposes to extend the coverage of communication by using the UAV relay, analyses the keytechnologies of spatial diversity receiving with equalization, low density parity check (LDPC) coding and etc., andthen designs the scheme of the relay system of UAV communication, and presents the performance analysis of theproposed communication relay scheme. The results of the performance analysis show that the proposed schemecan effectively solve the problem of the transmission distance and reliability for the information transmission ofthe UAV routing inspection over the horizon, and is of great value for the application of UAV to the electric powersystem.
