Flight conflict warning method of air traffic control system

Abstract

The invention relates to a flight conflict warning method of an air traffic control system. The air traffic control system comprises a data communicating 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 traffic control radar monitoring data and relevant automatic monitoring data and providing real-time tracking information for the control terminal module; the control terminal module comprises three sub-modules such as a preflight conflict-free 4D track creating sub-module, an in-flight short-term 4D track creating sub-module, and a real-time flight conflict monitoring and warning sub-module; the flight conflict warning method of the system is characterized in that flight planning data is treated by the control terminal module and 4D tracks are generated by a hidden Markov model, so that potential traffic conflicts under airspace traffic conditions can be analyzed. The flight conflict can be effectively warned by the flight conflict warning method and the security of the air traffic is also improved.

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 t
