A Boundary Division Method of Airspace Sectors Based on Guard Bands

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...

Problems solved by technology

The research results of the papers "Effect of Dynamic Sector Boundary Changes on air Traffic Controllers" and "Sector Design and Boundary Change Considerations for Flexible Airspace Management" show that the accuracy of sector boundary division directly affects the cognition and identification ability of controllers. In particular, the relationship between the position and distance between the route and the sector boundary and the shape of the sector have a particularly strong impact on the controller, which in turn affects the safety of airspace operations to a large extent
