Problems solved by technology

The multi-aircraft problem is much more complex in terms of calculation than two aircrafts, and it also has higher requirements for computational complexity. For the distance change between aircrafts caused by aircraft speed differences and route angles during flight Relevant research is still lacking

Embodiment Construction

[0089] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0090] like figure 1 As shown, the present invention mainly includes: initialization module, pairing of adjacent targets in airspace segmentation, calculation of collision factor based on ray intersection, calculation of route collision factor based on minimum time, calculation of route collision factor based on minimum distance, calculation of collision factor based on height, Establish a route collision model based on time-space correlation, and calculate route collision results. Combined with the flow chart, the specific implementation steps are as follows:

[0091] Step 1: Initialization.

[0092] The spatial range of the area is [0,P]×[0,Q], there are N targets, and the spatial rectangular coordinates are (x i ,y i ,z i ) (i＝1...N) ;

[0093] Step 2: Divide the area space, calculate the grid where each target is located, and all targets in a...

Abstract

The invention discloses a space-time correlation airway collision solving method based on airspace splitting, and aims to solve the problem of airway collision warning in a large-scale air traffic control system. A region splitting algorithm is adopted to reduce the ultra-large calculated amount of the whole airspace; a space is divided into several grids, the airway collision possibility betweenadjacent grids is calculated, an airway collision factor based on airway intersection, an airway collision factor based on minimum time, an airway collision factor based on minimum distance and a collision factor based on height are calculated, an airway collision model based on space-time correlation is established, and an airway collision index is calculated. According to the method, calculationcomplexity of airway collision for airplanes in the whole airspace is overcome, and multiple collision factors are introduced to rapidly and effectively solve problems of airway collision in the airtraffic control system.

Description

technical field [0001] The invention relates to the field of air traffic control, and more specifically, relates to a method for solving collisions of time-space associated routes based on airspace splitting. Background technique [0002] In recent years, the rapid development of the air transport industry in various countries has led to an increasing flow of air traffic, and the problem of flight conflicts has become increasingly serious. In order to ensure flight safety, research on collision risk has become an urgent problem to be solved. [0003] Ensuring safe flight of aircraft in the air and preventing aircraft collisions are the main tasks of air traffic control. In order to make effective use of airspace resources, increase traffic to the greatest extent and improve economic benefits while ensuring air traffic safety, it is necessary to plan rationally for airspace. Collision risk studies are an important part of the airspace planning process. In order to provide ...
