卫星通信在大型无人机输电线路巡检测控中的应用

摘要

Aiming at the bottleneck of measurement and control communication technology for large UAV transmission line inspection,this paper proposes a point-to-point satellite communication solution by analyzing and comparing various schemes.In the implementation of the technical scheme,the optimal selection and installation position of the airborne antennas are analyzed.The dual transmission diversity is used for forward transmission while the way of detecting the energy of the receiving signals is used for reverse transmission,which has effectively solved the signal blockage problems of satellite communication system by the helicopter rotors,resulting in the communication link interruption.The proposed method can effectively promote the application of large UAVs in power transmission line inspection,and further expands the use of satellite communication technology in civilian and military purposes.%针对大型无人机输电线路巡检的测控通信技术瓶颈,通过多种方案的分析和比较,提出了直接转发点对点方式卫星通信解决方案.在技术方案实施中分析评估了机载天线最佳选型和安装位置.前向利用双重发射分集的方法,返向利用检测接收信号能量的方式,有效地解决了卫星通信系统信号被直升机旋翼遮挡导致通信链路中断的关键技术问题,有力地推动大型无人机输电线路巡检实用化进程,并进一步拓展卫星通信技术在民用和军用领域的应用范围.
