[0066] figure 1 It is a flow chart of the airspace sector division method, and the specific implementation is as follows:
[0067] Step 1, extract the static structure information of the airspace, the method is as follows:
[0068] (1) According to the location information of key points (airports, waypoints, and conflict points) in the airspace, a key point coordinate database is established.
[0069] figure 2 It is to establish the static structure information flow chart of the airspace, figure 2 The key point coordinate database contains key point numbers and their corresponding coordinates, and the coordinates in the database are Cartesian coordinates converted from actual latitude and longitude coordinates.
[0070] (2) According to the route connections between key points, establish a route topology database.
[0071] figure 2 The airway connection in China can be described as whether there is an airway connection between two key points. If there is, the correspon...

The invention belongs to the field of air traffic management, and discloses a method for dynamically dividing a sector based on airspace traffic characteristics, which aims to confirm a sector division matched with airspace traffic changes according to airspace traffic change control, so as to realize optimal utilization of airspace resources. The method comprises three aspects, namely airspace information extraction, airspace modeling and sector optimized division algorithm. First, databases such as an airspace topological structure are constructed on basis of airspace static structural information and airspace dynamic information; then, a complicated network model is used for describing an airspace structure through regarding key points as nodes and air routes as sides; third, similarity of associated nodes in the complicated network model is calculated according to airspace dynamic information, a complicated weighing network is established, and an airspace convex cell model is established by utilizing the K-Means algorithm based on the complicated weighing network; and finally, the airspace convex cell model is combined with the hybrid coding genetic algorithm to obtain the final sector division result.
Description
technical field [0001] The invention belongs to the technical field of air traffic management, and relates to a method for extracting traffic characteristics by using airspace traffic information and dividing and adjusting the airspace sector structure based on the traffic characteristics. Background technique [0002] An important method in current air traffic control is to divide the airspace into several sectors, and each sector is controlled by one or more controllers. The division of airspace sectors directly determines the workload of each controller. Reasonable division of sectors is the key to ensuring traffic safety and efficiency. [0003] Airspace sector division is to divide the airspace into several control areas on the basis of ensuring control safety and flight safety, and distribute the workload of controllers in each sector in a balanced manner to ensure that the workload of each sector is within a reasonable threshold. The dynamic division of airspace is b...
