Commercial UAVs (Unmanned Aerial Vehicles, or drones) are increasingly being used for various purposes, such as geographic survey, rescue missions, inspection of industrial facilities, traffic monitoring and delivery of cargos and goods. In particular, the drones have great potential for life-saving operations. A missing person, for example, can be rapidly and effectively searched using a drone in comparison with the conventional search operations. However, there is no commercially available rescue UAV until now. The motivation for this study is to design an unmanned aerial vehicle capable of vertical takeoff and landing, while containing a high power propellant apparatus in order to lift a heavy cargo that contains rescue materials (such as water, food, and medicine). We used the EDF (Electric Ducted Fan) technology as opposed to the conventional motor and prop combination. The EDF can produce the power about three times higher than the motor-prop combination. This became suitable for transportation of rescue goods, and can be widely used in rescue operations in natural environments. Based on these results, the UAV for rescue material transport capable of heavy vertical takeoff and landing is developed, including airframe, flight control computer and GCS (ground control station).展开更多
文摘针对无人机频繁闯入禁飞区域,引发安全事故,地理围栏作为一种无人机领域的"新"技术被提出。论文主要研究实现基于Google Earth无人机地面站系统的地理围栏,作为一种在无人机安全中起着重要作用的应用,在地面站Google地图中为无人机划分禁飞区域,防止无人机"黑飞"、"乱飞"事故,提高无人机的安全性能。其中地理围栏算法是关键,论文主要介绍多边形和圆形两种典型的算法,在Visual Studio 2010.NET的开发环境下,利用Google Earth的插件,模拟仿真无人机两种地理围栏的实现效果。后续进一步研究将地理围栏技术应用于无人机的飞行控制系统,用于提高无人机自治水平,不用通知地面站操作人员操控无人机避让禁飞区域,实现自主避让,对无人机的安全应用具有一定的意义。
