为消除无人机在高速公路巡检中的安全隐患,避免由于碰撞而导致的坠地等风险,基于对无人机巡检防碰撞体系及其自主防碰撞执行过程的研究,采用三维动态碰撞预测与最优问题动态碰撞规避算法,提出一种适用于三维空间的无人机动态碰撞避让技术,并借助5G通信技术搭建空中与地面通信网络,保证无人机在遇到随机障碍物时可保持最小安全间距。经仿真,本文无人机防碰撞技术在算法运行效率、航路代价以及航路质量3方面均优于最优几何分析无人机防碰撞技术,避让策略行之有效。

In order to eliminate UAV potential safety hazard in expressway patrol, and avoid the crash risk because of collision, the paper uses 3 D dynamic collision prediction and optimal problem dynamic collision avoidance arithmetic to propose an UAV dynamic collision avoidance technology that is appropriate for three-dimensional space. And then, it uses 5 G communication technology to construct communication network, when UAV meet random obstacle, it can make it maintain smallest safety clearance. Simulation results show that, paper’s technology is better than the technology based on optimal geometric in algorithm efficiency, route cost and route quality 3 aspects, the collision avoidance strategy is useful.
