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。
Aiming at the bottleneck of the monitoring and control communication technology for the inspection of large UAV transmission lines, this paper proposes a solution of direct forwarding point-to-point satellite communication through the analysis and comparison of various schemes. In the implementation of the technical program, the best selection and installation position of the airborne antenna is analyzed and evaluated. The method of forward transmit diversity is used to detect the energy of the received signal and the signal of the satellite communication system is effectively blocked by the helicopter rotor The key technical issues that lead to the interruption of the communication link effectively promote the practical application of inspection of transmission lines for large-scale UAVs and further expand the application range of satellite communication technologies in civil and military fields.
