危险天气下的实时动态改航策略研究

Research on Real-time Dynamic Rerouting Strategy in Dangerous Weather

为提高危险天气下的飞行安全性,降低管制员雷达引导绕飞危险天气区域的工作负荷,优化航空器在危险天气下的改航路径,首先构建编码空域信息矩阵,用栅格化的方法表示危险天气区域,定义危险天气区域的移动方向和速度,明确区域内危险天气区域对航路航线的安全威胁;进而针对移动的危险天气区域对空域内航路航线的影响,提出基于改进人工势场法的实时动态改航策略,让航班能够尽快绕过动态危险天气区域,从而提高空域的利用率。结果表明:基于改进人工势场法的实时动态改航策略,能够完成在动态环境下的最优路径选取的任务,快速高效地规划并选取出一条路径,并随环境的变化相应地改变,具有一定的稳定性和较强的适应能力。

In order to improve flight safety in dangerous weather,reduce the workload of the controller’s radar guidance around the dangerous weather area,and optimize the aircraft’s diversion path in dangerous weather,a coded airspace information matrix was built and a rasterized method was used to represent the danger Weather area,define the moving direction and speed of the dangerous weather area,and clarify the safety threat of the dangerous weather area in the area to the air route;and then,for the impact of the moving dangerous weather area on the air route in the airspace,a real-time method based on the improved artificial potential field method is proposed.The dynamic diversion strategy allows flights to bypass the dynamic dangerous weather area as soon as possible,thereby ensuring the utilization rate in the airspace.The results show that the real-time dynamic diversion strategy based on the improved artificial potential field method can complete the task of selecting the optimal route in a dynamic environment,plan and select a route quickly and efficiently,and change accordingly with the change of the environment,with certain stability and strong adaptability.
