【摘要】:自改革开放以来,随着国民经济的持续增长,我国民航事业得到了快速的发展,有限的空域资源与交通流量不断增加之间的矛盾日益突出,在交通较为密集的终端区尤为显著,使得航空器间飞行冲突的可能性大大增加,加重了管制员的工作负荷。为保证航空器间的飞行间隔确保其飞行安全,亟需有效的冲突探测工具,辅助管制员对航空器的间隔进行调配。基于此,本文对冲突探测技术进行系统、深入的研究。 有效的冲突探测基于准确的航迹预测,准确航迹预测是冲突探测的根本。航迹预测方面,首先分析了当前航迹预测的系统模型,建立基于BADA飞行性能模型的航迹预测方法,并利用北京首都机场36L跑道的进场航线进行仿真,将预测结果与实际雷达数据进行对比分析;提出一种新的航迹预测方法:将航空器航迹预测问题就变为混杂系统的状态估计问题,并根据航空器的运行特点和飞行计划信息,建立了状态相关模式转移多模型估计算法。 冲突探测方面,首先详细介绍了终端区航空器安全间隔标准规定、航空器飞行保护区模型,然后对于确定型和概率型的冲突探测算法进行分析,对CTAS系统的Paielli算法的缺陷进行修正,提出了一种适用性更加广泛的短期冲突探测算法。基于前面的航迹预测结果应用此算法进行仿真分析,与目前终端区使用的短期冲突告警工具STCA对比,能够有效降低虚警率,,体现此算法的优越性。 最后,在上述的航迹预测和冲突探测算法的基础上,本文开发了冲突探测系统。该系统满足虚报率低、实时性高的要求,同时界面友好、操作简单,为终端区的短期冲突告警提供了一种切实可行的方法。
[Abstract]:Since the reform and opening up, with the sustained growth of the national economy, the civil aviation industry in China has been developing rapidly. The contradiction between the limited airspace resources and the increasing traffic flow has become increasingly prominent, especially in the transport dense terminal area. Making inter-aircraft flight conflicts much more likely and increasing the workload of controllers. In order to ensure the safety of flights between aircraft, effective conflict detection tools are urgently needed, Based on this, the conflict detection technology is studied systematically and deeply in this paper. Effective conflict detection is based on accurate track prediction, which is the basis of conflict detection. In the aspect of track prediction, firstly, the current system model of track prediction is analyzed, and the method of track prediction based on BADA flight performance model is established. The approach route of 36L runway of Beijing Capital Airport is simulated and compared with the actual radar data. A new route prediction method is proposed: the problem of aircraft track prediction is transformed into a hybrid system state estimation problem. According to the flight plan information and the characteristics of the aircraft, a multi-model estimation algorithm for state dependent mode transfer is established. In the aspect of conflict detection, first of all, the standard of aircraft safety interval in terminal area and the model of aircraft flight protection area are introduced in detail, and then the conflict detection algorithms of certain and probabilistic types are analyzed. In this paper, the defects of Paielli algorithm in CTAS system are corrected, and a more widely applicable short-term conflict detection algorithm is proposed. Compared with the short-term conflict alarm tool STCA which is used in the terminal area, it can effectively reduce the false alarm rate and reflect the superiority of this algorithm. Finally, on the basis of the above algorithms of track prediction and collision detection, a conflict detection system is developed, which meets the requirements of low false report rate, high real-time performance, friendly interface and simple operation. It provides a practical method for short-term conflict alarm in terminal area.
