Conflict detection and resolution method for large-scale airspace usage plan based on grid model

Abstract

The invention provides a large-scale airspace use plan conflict detection and relief method based on a grid model. The method grids the airspace environment according to the airspace use plan, and performs grid discrete and digital coding on continuous airspace; The airspace grid built-in attribute of the primary key digitally describes the airspace occupancy relationship; establishes a grid model-based airspace digital description method to realize the grid representation of the traditional airspace shape; establishes an airspace conflict function and uses the grid built-in attributes to calculate and determine multiple airspaces Use the planned conflict airspace; design a 4-dimensional translational airspace conflict resolution algorithm to achieve dynamic resolution of airspace conflicts. The present invention can not only quickly and effectively detect the airspace conflict position and range of large-scale air use plans, but also can solve the airspace relief method online. The whole process is calculated by grid coding, which reduces the computational complexity and effectively improves the computational efficiency.

Description

technical field [0001] The invention belongs to the technical field of airspace conflict detection and relief, in particular to a large-scale airspace use plan conflict detection and relief method based on a grid model. Background technique [0002] Airspace conflict detection and resolution technology is a key component to ensure the safe operation of my country's airspace and the orderly progress of airspace use plans. As the international situation becomes increasingly tense, my country's military airspace use plans become more frequent, military-civil aviation conflicts and military-service conflicts continue to escalate. How to quickly and accurately identify the conflicting airspace in the airspace usage plan and provide a solution to the conflict in real time is a key issue in the future large-scale collaborative airspace designation. [0003] The research on airspace conflict detection began in the 1940s and 1950s. Many scholars at home and abroad have proposed a vari...

AI Technical Summary

Problems solved by technology

[0003] The research on airspace conflict detection began in the 1940s and 1950s. Many scholars at home and abroad have proposed a variety of related models and algorithms. The edge is crossed to determine whether there is airspace charging. Although this method can accurately calculate the airspace use plan conflict and the range of conflicting airspace, there are problems such as long calculation time and low efficiency for large-scale airspace conflict detection.

Research on airspace conflict resolution currently focuses on the conflict detection and resolution of aircraft flight routes, and there are few research results on airspace conflict and resolution between a large number of airspace use plans
