The invention discloses a method for generating a geometric structure of a low-altitude airway network for safe distance constraint. The method comprises the following steps: establishing an airway network general model; generating a route structure: on the basis of generating a route basic geometric structure, determining basic structure parameters of each route, and calculating to obtain safetydistance constraint conditions of all routes and corresponding isolation belt widths by taking the purpose that the distance between unmanned aerial vehicles in different channels is greater than an obstacle avoidance distance; and generating an intersection structure: on the basis of generating the basic geometric structure of the intersection, calculating to obtain safe distance constraint conditions and corresponding radiuses of all intersections by taking the distance between unmanned aerial vehicles located in the intersection as a purpose of being greater than an obstacle avoidance distance, and updating isolation strip widths of part of airways. According to the invention, the airway network model composed of a plurality of geometric structural bodies can be automatically generated,the pressure of a low-altitude traffic control system is reduced, and safe and orderly operation of air traffic is facilitated.

    本发明公开了一种面向安全距离约束的低空航路网几何结构生成方法,包括:建立航路网通用模型;生成航路结构:在生成航路基本几何结构的基础上,确定每个航路的基本结构参数,以位于不同航道内的无人机之间的距离大于避障距离为目的,计算得到所有航路的安全距离约束条件和对应的隔离带宽度;生成交叉路口结构:在生成交叉路口基本几何结构的基础上,以位于交叉路口内的无人机之间的距离大于避障距离为目的,计算得到所有交叉路口的安全距离约束条件和对应的半径,以及更新部分航路的隔离带宽度。本发明能够自动生成具有由若干几何结构体组成的航路网模型,减轻低空交通控制系统的压力,有助于空中交通安全、有序运行。
