| 摘 要： | 无人机曾发生UHF上、下行链路和C链路陆续中断,全程持续约20 min。从视距链路系统功能原理出发,定位故障原因,分析故障机理,确定中断原因分别为区域内存在干扰信号、任务管理处理机中OFP软件存在缺陷和应急处置错误选择了定向天线的伺服方式。最后采取了针对性改进措施,彻底解决了视距链路主备全断故障。该故障解决进一步完善了应急处置体系,对于预防危险性故障,提高系统整体可靠性具有重要意义。

| Abstract: | Interruption exception occurred to the uplink and downlink of UHF and C link of an unmanned aircraft. The failure cause and mechanism were analyzed based on the working principle of the stadia line. It is found that the failure causes include the existence of regional interference signal, the defection of OFP software of task management system, the wrong use of directional antenna servo in emergency disposal. Finally, improvement measures were taken to solve the problem of the interruption exception of the stadia link, and the emergency disposal system was perfected. |
