随着智能交通运输体系的逐渐完善和无人机应用场景的不断拓展,无人机越来越多地应用于城市低空空域。研究对象上,本文聚焦无人机城市低空运行场景,研究无人机之间、无人机与飞鸟之间的碰撞风险。研究方法上,基于改进Reich模型计算无人机之间的碰撞风险,同时融合城市低空因素建立基于位置误差的碰撞风险模型探究飞鸟与无人机之间的碰撞风险。最后通过设置不同航路场景计算不同航路构型下的碰撞风险。经实例验证,本文提供的计算方法能够有效计算碰撞风险,为无人机的风险管控提供一定思路。

With the gradual improvement of the intelligent transportation system and the continuous expansion of UAV application scenarios,UAVs are increasingly used in urban low-altitude airspace. As for the research object,this paper focuses on the urban low-altitude operation scenario of UAVs and studies the collision risk between UAVs,and between UAV and flying birds. In terms of research methods. A collision risk between UAVs is calculated based on the improved Reich model,and a collision risk model based on position error is established by integrating urban low-altitude factors to explore the collision risk between flying birds and UAV. Finally,the collision risk under different route configurations is calculated by setting different route scenarios. It is verified by an example that the calculation method provided in this paper can effectively calculate the collision risk and provide a certain idea for the risk management and control of UAV.
