Control method of air traffic control system

Abstract

The invention relates to a control method of an air traffic control system. The air traffic control system comprises a data communication module, a monitoring data fusion module, an airborne terminal module and a control terminal module; the monitoring data fusion module is sued for fusing air traffic control radar monitoring data and automatic related monitoring data so as to provide real-time track information to the control terminal control; the control terminal module comprises a preflight conflict-free 4D track generation sub-module, an in-flight short-period 4D track generation sub-module, a real-time flight conflict monitoring and warning sub-module and a flight conflict resolution 4D track optimization sub-module. The air traffic control method of the system is that the flight plan data are processed through the control terminal module, and a 4D track is generated through a hidden markov model, so as to analyze the potential traffic conflict of the air traffic condition; the optimal resolution scheme is provided by the model predictive control theory method. By adopting the control method of the air traffic control system, the flight conflict can be effectively prevented, and thus the safety of air traffic can be improved.

Description

technical field [0001] 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 [0002] 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. [0003] 4D track is a precise description of the ...
