Abstract

The invention discloses a guard band-based partitioning method of air sector boundaries. On the basis of the clustering of the controller's workload, the present invention first establishes the route protection zone and the airport protection zone according to the minimum distance constraint, then constructs a polygon for each class based on the protection zone, and uses the polygon as a generalized base point in A generalized Vonoroi diagram composed of polygons is generated between each polygon, and finally the edges in the generalized Vonoroi diagram are processed to form the boundary of the airspace sector. The method of the present invention can ensure that the aircraft will not continuously cross the boundary of the airspace sector and cause the occurrence of control failure by setting the protective belt; and the shape of the airspace sector is a polygon with as few sides as possible, so that the airspace sector Zone boundaries do not change too much to affect controller identification.

Description

technical field

[0001] The invention belongs to the technical field of air traffic management, and in particular relates to a method for dividing boundaries of airspace sectors based on guard bands. Background technique

[0002] In air traffic management, airspace sector division plays a vital role in ensuring air traffic safety. Airspace sectorization is generally achieved through controller workload clustering and sector boundary determination. Workload clustering is the division of controller workload within a given airspace into parts, each part called a class. This division is determined according to the principle that the workload of each category does not exceed the maximum value that the controller can bear and that the load among categories is balanced. There are many ways to realize classification, such as quartz growth method, dichotomy method, genetic algorithm and so on. Since the aircraft is flying along the route, the resulting workload of the controller is...

Embodiment Construction

[0020] Attached below Figure 1-7 The present invention is described in further detail.

[0021] In an embodiment of the present invention, a guard band-based airspace sector boundary division method comprises the following steps:

[0022] S101. Establish a square airport protection belt with the airport as the center, and establish a flight protection belt with the boundary parallel to the flight line with the airway as the symmetrical axis. The side length of the airport protection belt and the width of the airway protection belt are both 2d, and d is greater than or equal to the minimum safety zone. distance;

[0023] S102. Take each classification point on each route as the center, draw two straight lines perpendicular to the route where the classification point is located, and intersect the borders of the route protection zone on both sides of the classification point to obtain a square with a side length of 2d 4 intersections of vertices; connect all intersections and ...
