【摘要】：随着航空运输量以及航班量的不断增加，管制员、飞行员的工作负荷的不断增大，使得跑道侵入事件日益增多，严重威胁着航空安全。在日常航空运行中，跑道是航空器地面运动中最重要的场所之一，，因为超过一半的飞行事故发生在航空器起飞和降落阶段，因此，加强跑道安全管理，深入跑道侵入探测及告警的研究尤为重要。我国关于跑道侵入的研究与国外相比起步较晚，因此我国关于防止跑道侵入的技术和措施并不是很成熟。在本文中我们详细的论述了跑道侵入的原因、以及目前常用的防止跑道入侵的技术与手段；并在此基础上确定了由升降带、滑行道等待位置、跑道端安全区、仪表着陆系统保护区以及空中保护区组成的三维立体结构下的跑道侵入保护区；并根据保护区和航空器的多边形结构，通过计算机语言，利用API函数实现了航空器外形与保护区的模拟仿真，并采用两个多边形相交算法确定了航空器与保护区之间的位置关系；然后运用射线法对闯入保护区的航空器之间的冲突实施探测；最后，通过计算机编程，建立了机场跑道冲突探测及告警（软件）系统。在该系统中我们生动的显示了各种跑道冲突类型，及时的为管制员提供视觉和听觉上的告警。本文所研究的防止跑道侵入冲突探测及告警系统简单、易懂并且具有较好的实用性，可以推广到各个未安装高级地面监控设备的中小型机场，用来降低跑道侵入的概率,增强空中交通管理部门的综合保障能力。
[Abstract]:With the increase of air traffic volume and flight volume, the workload of controllers and pilots is increasing, which makes the runway intrusions increase day by day, which seriously threatens the aviation safety in the daily aviation operation. Runway is one of the most important places in aircraft ground movement, because more than half of flight accidents occur in the take-off and landing stages of aircraft, therefore, runway safety management should be strengthened. It is very important to study the detection and warning of runway intrusion. The research on runway intrusion in our country started relatively late compared with foreign countries, so the technology and measures to prevent runway intrusion in our country are not very mature. In this paper, we discuss the reasons of runway intrusion in detail. And the commonly used technology and means to prevent runway intrusion; On this basis, the runway intrusion protection area under the three-dimensional structure is determined, which is composed of landing belt, taxiway waiting position, runway terminal safety zone, instrument landing system protection area and air protection zone. According to the polygonal structure of the protected area and the aircraft, the simulation of the aircraft shape and the protected area is realized by using the API function through the computer language. The position relationship between aircraft and protected area is determined by the algorithm of intersection of two polygons. Then the conflict between the aircraft intruding into the protected area is detected by ray method. Finally, through computer programming, an airport runway conflict detection and alarm (software) system is established, in which we vividly display various types of runway conflict. Provide visual and auditory alarms to controllers in a timely manner. The system of preventing runway intrusion conflict detection and warning is simple, easy to understand and has good practicability. It can be extended to the small and medium-sized airports without advanced ground monitoring equipment. It is used to reduce the probability of runway intrusion and enhance the integrated support capability of air traffic management department.
