Air traffic control method based on 4D flight path operation

Abstract

The invention relates to an air traffic control method based on 4D flight path operation. The method is implemented through an air traffic control system, and the air traffic control system comprises a data communication module, a monitoring data fusion module, an airborne terminal module and a control terminal module, wherein the monitoring data fusion module is used for fusing air control radar monitoring data with automatic related monitoring data and providing real-time flight path information for the control terminal module; the control terminal module comprises a preflight conflict-free 4D flight path generation submodule, a flight medium and short term 4D flight path generation submodule, a real-time flight conflict monitoring and alarming submodule and a flight conflict resolution 4D flight path optimization submodule. According to the air traffic control method based on 4D flight path operation of the system, the control terminal module is used for processing flight plan data and generating 4D flight paths through a hidden Markov model to analyze potential traffic conflicts of airspace traffic conditions, and a model prediction control theoretical method is adopted to provide the optimal resolution scheme. The method can effectively prevent flight conflicts and improve air traffic safety.

Description

[0001] This application is a divisional application of the invention patent application with the application number: 201510008164.3, the title of the invention is "A Control Method for Air Traffic Control System", and the application date is: January 7, 2015. technical field [0002] The present invention relates to an air traffic control system and method, in particular to an air traffic control system and method based on 4D track operation. Background technique [0003] With the rapid development of the global air transport industry and the increasingly prominent contradiction between the limited airspace resources, in the complex airspace with dense air traffic flow, the air traffic management method that still adopts flight planning combined with interval allocation gradually shows its backwardness, as shown in: ( 1) The flight plan does not configure accurate air traffic control intervals for aircraft, which may easily cause congestion in the tactical management of traff...

[0003] With the rapid development of the global air transport industry and the increasingly prominent contradiction between the limited airspace resources, in the complex airspace with dense air traffic flow, the air traffic management method that still adopts flight planning combined with interval allocation gradually shows its backwardness, as shown in: ( 1) The flight plan does not configure accurate air traffic control intervals for aircraft, which may easily cause congestion in the tactical management of traffic flow and reduce airspace security; (3) Air traffic control still focuses on maintaining a safe separation between individual aircraft, and it is difficult to upgrade to strategic management of traffic flow
