Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 As shown, the method for quickly detecting flight conflicts based on adjacent grids provided by the present invention includes the following steps carried out in order:

[0019] Step 1. Divide the target airspace: set the abscissa of the boundary point of the target airspace as [x 1 ,x 2 ,...,x n ], the vertical coordinate is [y 1 ,y 2 ,...,y n ], the maximum and minimum values ​​of the abscissa are x max 、x min , the maximum and minimum values ​​of the ordinate are respectively y max 、y min . Then the coordinates of the smallest circumscribed rectangle of the target airspace on the horizontal plane are [x max ,x min ,y max ,y min ]. Further set the specified horizontal separation standard between adjacent aircraft as D h , the vertical separation standard between adjacent aircraft is D v , then the smallest circ...

Abstract

The invention provides a flight conflict fast detection method based on adjacent grids. The flight conflict fast detection method includes the steps that a target airspace is divided; aircraft coordinates are extracted; grid airspaces to which aircrafts belong are determined; adjacent aircraft sets are extracted; and the conflicts of the adjacent aircrafts are detected. The flight conflict fast detection method based on adjacent grids has the beneficial effects that the method based on the adjacent grid airspaces is adopted, the flight conflicts smaller than a specified interval standard can be detected accurately and quickly in large-scale air traffic, the method is not affected by human factors, and an assessment method is simple and easy to use.

Description

technical field [0001] The invention belongs to the technical field of air traffic management, in particular to a method for quickly detecting flight conflicts based on adjacent grids. Background technique [0002] The detection of flight conflicts between aircraft is the basis for ensuring the safety of air transportation. The traditional detection method is to judge all aircraft in pairs, which has low efficiency and slow detection speed, and cannot adapt to the current increasingly busy air traffic situation. After the airspace is divided into grids, the detection of flight conflicts based on adjacent grids has high speed and reliable performance, and it is a fast method suitable for detecting flight conflicts in large-scale air traffic. It can make up for the deficiencies of current technologies and methods, and provide a foundation for the construction of a new generation of air traffic systems. Contents of the invention [0003] In order to solve the above problems...
