Flight conflict early warning method for air traffic control system

Abstract

The invention relates to a flight conflict early warning method for an air traffic control system. The air traffic control system comprises a data communication module, a monitor data fusion module, an airborne terminal module and a control terminal module. The monitor data fusion module is used for realizing fusion between air traffic control radar monitor data and automatic related monitor 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, an in-flight short-term 4D flight path generation submodule and a real-time flight conflict monitor and alarm submodule. According to the flight conflict early warning method for the air traffic control system, flight planning data are processed through the control terminal module, a 4D flight path is generated through a hidden Markov model, and potential traffic conflicts of airspace traffic situations are analyzed. The flight conflict early warning method for the air traffic control system can effectively and early warn flight conflicts and improve safety of air traffic.

Description

technical field [0001] The invention relates to an air traffic control system and method, in particular to a method for predicting aircraft trajectories and pre-warning flight conflicts by an air traffic control system 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 tr...

Problems solved by technology

[0004] The air traffic operation mode based on trajectory operation needs to calculate and optimize the flight path of a single aircraft at the strategic level, coordinate and adjust the traffic flow composed of multiple aircraft; trajectory to solve the congestion problem, and to ensure the operational efficiency of all aircraft in the traffic flow; and to predict the conflict and optimize the relief plan at the tactical level, it is very dependent on the ability to accurately predict the trajectory of the aircraft and analyze the flight conflict. Early warning, at present, it is impossible to accurately predict the trajectory of the aircraft in real time, and the real-time performance is particularly poor
