Abstract

ICAO has emphasized that aeronautical information agencies should provide digitized aeronautical data and information, and realize that aeronautical data exchanging internationally in AIM. The AIXM structured aeronautical information dataset will be the main source of aeronautical basic data in the aeronautical information exchange network. In this article, the authors first analyze the spatio-temporal attributes of AIXM dataset and design the query method of AIXM structured obstacle data based on the research of AIXM coding specification. Secondly, the helicopter path planning is taken as the research scenario. Using the AIXM obstacle dataset and route dataset, combining the helicopter performance constraints to construct the envelope frame for collision judgment, and a new path planning method with improving the classical A* algorithm based on the AIXM dataset is proposed. The proposed method is validated and visualized. The validation results show that the proposed method reduces the frequency of helicopter turning, and ensures the safe distance between the flight path and the obstacles.
基于AIXM数据集的直升机路径规划方法
国际民航组织强调,航空情报机构应提供数字化的航空数据和信息,并在AIM中实现航空数据的国际交换。AIXM结构化航空信息数据集将成为航空信息交换网络中航空基础数据的主要来源。本文首先分析了AIXM数据集的时空属性,在研究AIXM编码规范的基础上,设计了AIXM结构化障碍物数据的查询方法。其次,以直升机路径规划为研究场景。利用AIXM障碍物数据集和航线数据集,结合直升机性能约束构造包络框架进行碰撞判断,提出了一种基于AIXM数据集改进经典a *算法的路径规划新方法。对该方法进行了验证和可视化。验证结果表明,该方法降低了直升机转弯频率,保证了飞行路径与障碍物之间的安全距离。
