Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0047] 1. Principle of the present invention

[0048] Firstly, the airspace resources to be allocated are discretely divided into several "three-dimensional small squares", and the size of the "three-dimensional small squares" is equal to the size of the aircraft safety interval space, and the airspace resource model is constructed. Then use the theoretical knowledge of petri nets to model the operation process of aircraft in the airspace resource model, and construct the airspace resource operation model; The flight track in the model is predicted, and the "small three-dimensional cube" occupied by each aircraft and the occupied time are predicted. Finally, according to the airspace conflict judgment rules and detection algorithms, the aircraft with conflicts in the use of airspace resources and the conflict areas of airspace resources are deduced . ...

Abstract

The invention discloses an airspace conflict detection method and system based on aircraft track prediction. According to the aircraft use plan of each airspace user, the longitude, latitude and altitude track information of each aircraft at each time in the future is predicted, combined with the planning Allocate the size of airspace resources, propose an airspace resource allocation plan that meets the needs of each airspace user as much as possible, avoid the compromise of airspace range and time for each airspace user, and maximize airspace utilization.

Description

technical field [0001] The invention relates to the technical field of airspace management, in particular to an airspace conflict detection method and system based on aircraft trajectory prediction. Background technique [0002] With the increasing development of the civil aviation transportation industry, the use of airspace is increasing. At the same time, there are more and more airspace users such as launch vehicles, artillery, and low-altitude aircraft. The air traffic system in our country is facing more and more serious airspace congestion. situation. How to effectively utilize airspace resources has become an urgent problem faced by airspace management departments. Usually, the airspace management department will use some technical aids to plan and manage airspace resources to ensure the safety and stability of airspace operations. Among them, airspace resource use conflict detection is an important content of airspace resource planning. It mainly refers to organiz...
