Problems solved by technology
The multi-airport terminal area has remarkable characteristics such as intricate airspace structure, coupling and correlation between airports, dense air traffic flow, diverse control and operation rules, and dynamic and changeable operating environment. At present, air transport managers are still unable to conduct scientific research on their huge airspace network. Topological processing makes it difficult to simplify the classification and specific measurement of its complex network structure characteristics, and the cognitive level of airspace ontology attributes is relatively low, which directly increases the difficulty of operation and management of multi-airport terminal areas
[0006] At present, there are very few technical achievements in multi-airport route network topology modeling at home and abroad, and there are still some gaps in the field.

The invention discloses a topological modeling method of a multi-airport terminal area course network. Resource characteristics of the multi-airport terminal area course network are analyzed scientifically, structural parameters of the course network are measured accurately, course common reference points including runways, intermediate leg points, disperse leg points, gathering cross points of legs and approaching / departure points are integrated in a classified manner, key nodes are extracted from the common reference points, topology analysis, abstraction and simplification of the multi-airport terminal area course network are realized, and significant technical supports are provided for constructing a digital spatial-domain model of multi-airport terminal areas rapidly, identifying physical structural features of the course network accurately, and optimizing the spatial-domain structure of the multi-airport terminal areas scientifically. The method can be used to enhance the digital modeling capability of the terminal area course network, and effectively solve the technical problems that spatial-domain network abstract modeling of the multi-airport system is extremely complex and the spatial-domain and the spatial-domain structural characteristic are hard to measure.
Description
[0001] Technical field: [0002] The invention relates to a multi-airport system airspace modeling method, in particular to a multi-airport terminal area route network topology modeling method, which belongs to the field of complex airspace system resource management and control. [0003] Background technique: [0004] With the continuous increase in the number of airports, the continuous expansion of construction scale and the continuous concentration of geographical distribution, the strategic layout of "one city with two airports" or "one city with multiple airports" has begun to take shape, and the trend of coordinated development of multi-airport systems has become more and more obvious . Especially in the three major regions of my country's Yangtze River Delta, Pearl River Delta and Beijing-Tianjin-Hebei, the airport cluster effect is having a very important impact on airport operation command and air traffic management. As the key bottleneck resource of multi-airport sy...
