低空任务空域内建筑物与无人机碰撞风险概率研究

Research on the Risk Probability of Collision between Buildings and UAV in Low-altitude Mission Airspace

为研究无人机低空运行时与建筑物的碰撞风险概率,基于二维矩阵模型的ABC分类法将低空空域分为A、B、C三层,建立类胶囊型无人机碰撞盒,并建立无人机与建筑物的碰撞风险模型。通过蒙特卡洛模拟统计不同低空任务空域环境内无人机与建筑物的碰撞风险概率,系统的分析仿真结果,证明该模型具有可行性。当改变任务空域范围或机型尺寸、巡航速度、建筑基地使用面积以及建筑物高度时,建筑物与无人机的碰撞风险会随着改变,且两者具有正比关系。

In order to study the collision risk probability between uav and building during low-altitude operation,ABC classification based on two-dimensional matrix model divides the low-altitude airspace into three layers:A,B and C,and the capsule-like uav collision box is established,and the collision risk model between uav and building is established.Through Monte Carlo simulation statistics of the collision risk probability between UAV and building in different low-altitude mission airspace environments,the systematic analysis and simulation results,to prove that the model is feasible.When changing the mission airspace range or model size,cruise speed,the service area of the building base and the building height,the collision risk between the building and the UAV will change with it,and there is a proportional relationship between the two.
