民航机场运动目标实时运动仿真

Real-time Motion Simulation of Moving Targets in Civil Aviation Airport

对机场地面保障过程中的地面运动目标实时运动过程建立数据关联模型和运动仿真数学模型,基于GIS地理数据与图形设备接口(GDI+),结合多线程技术与并发同步机制对仿真程序加以改进;仿真过程中利用改进的A~*算法确定机场运动目标行驶最佳路径,结合数据可视化技术实时监测目标运动状态,最终利用复演法进行多次试验对仿真结果进行统计分析.该仿真模型现已应用于机场地面保障流程推演、机场应急预案验证、机场航班运输决策等多个领域,对提高机场航班过站保障能力具有重要意义.

A data association model and a mathematical motion simulation model are built for the real-time motion process of ground moving targets in ground support of airports.The simulation program is improved on the basis of the GIS geographic data,graphics device interface(GDI+),multithreading technology,and concurrent synchronization mechanisms.In the simulation process,the improved Aalgorithm is used to determine the best driving path of moving targets at airports,and the moving states of the targets are monitored in real time using data visualization technology.Finally,the repetition method is employed to carry out multiple tests for statistical analysis of the simulations.The simulation model has been applied to many fields,such as the deduction of the ground support process of airports,airport emergency plan verification,and flight transportation decision-making.It is of great significance to improve the ability of airports to support flight transit.
