Embodiment Construction

[0044] In order to make the purpose, technical solution and advantages of the present invention clearer, the content of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0045] The shape of airspace in the horizontal dimension is divided into four categories: convex polygon, circle, sector and runway. The shape of airspace in the horizontal dimension does not have concave polygon, because concave polygon airspace is very inconvenient for aircraft to move in the airspace. So the shape of the airspace in the horizontal dimension does not include concave polygons.

[0046] In one embodiment of the present invention, the projections of all airspaces in a certain area on the horizontal dimension are placed in the same two-dimensional plane Cartesian coordinate system, the horizontal axis of the coordinates is the X axis, and the vertical axis of the coordinates is the Y axis. Conflict detection in the ho...

Abstract

The invention provides a horizontal dimension airspace conflict detection method. The method comprises the steps of constructing direction bounding boxes, performing intersection detection on the direction bounding boxes, and performing convex polygon intersection detection and horizontal safety interval detection on the intersected direction bounding boxes. According to the method, the direction bounding boxes are constructed, intersection detection of the direction bounding boxes is carried out firstly, airspace pairs needing refined conflict detection are screened out more accurately, the screening effect is good, the operand of subsequent polygon intersection detection can be reduced, and the overall operation efficiency is improved. When polygon intersection detection is carried out, the shortest distance of the projection polygon of the airspace on the horizontal plane is calculated, and has advantages that, compared with the horizontal safety interval between the airspaces, missed detection is prevented, and the accuracy of airspace conflict detection on the horizontal dimension is improved.

Description

technical field [0001] The invention belongs to the technical field of air traffic management, in particular to an airspace conflict detection method. Background technique [0002] The speed, heading, and altitude of civil aviation aircraft do not change much during flight. Therefore, the position of the aircraft in the future can be predicted based on the current position of the civil aviation aircraft and the navigation parameters, so as to detect flight conflicts in advance. However, in addition to civil aviation aircraft, there are also military aviation aircraft in the sky. In addition, all types of unmanned aerial vehicles, artillery shells, and missiles must be launched with empty space. The elements of navigation change extremely fast, and the flight status and position are extremely difficult to predict; in wartime, there will be thousands of pieces of weaponry and equipment operating together in the same time unit and limited battlefield space, so it is impossible ...
