摘要
在地震现场应急通信中,为满足无线图传系统等通信设备在复杂地形进行大范围和远距离通信作业的需求,提出利用系留式无人机中继通信系统保障无线电(超短波)的远距离传输。目前,对该系统的研究还处于理论分析和试验阶段,尚未在地震应急中得到大范围的推广应用。本研究利用多次试验的数据,分析验证系留式无人机供电系统的可行性及实用性,定量计算中继通信系统的升空效益,并形成一套完整的、可操作性强的系统实施方案。在城区、郊区以及起伏较低的山地、丘陵等地区,实现了移动图传系统在距离通信车5—10km范围内稳定、实时、快速的数据传输。
In the emergency communications of earthquake site, wireless mapping system equipment needs to adapt to complex terrain and long distance communication operations. The tethered UAV Relay system is currently in the theoretical analysis and experimental stage, and has not yet been a wide range of practical promotion in the earthquake emergency site. Based on multiple experimental studies, we analyzed and verified its feasibility and practicability. At the same time, we quantitatively estimated its ability raising the height increases the effect. The results of this experimental study can be used to provide a reliable basis and pre-prepared in the application of the system in the earthquake site. Meanwhile, it can used to improve the existing earthquake site emergency communication system.
