Problems solved by technology

[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 precise air traffic control intervals for aircraft, which may easily cause congestion in traffic flow tactical management and reduce airspace security; (2) The flight plan-centered air traffic control automation system calculates the flight profile and (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

Embodiment Construction

[0061] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0062] The air traffic control system based on 4D track operation of the present invention, such as figure 1 As shown, it includes an airborne terminal module 101 , a data communication module 102 , a surveillance data fusion module 103 , and a control terminal module 104 . The specific implementation of each part will be described in detail below.

[0063] 1. Airborne Terminal Module

[0064] The airborne terminal module 101 is an interface for pilots to obtain ground control instructions, refer to 4D flight tracks, and input flight intentions, and is also an interface for collecting current aircraft position data.

[0065] like figure 2 As shown, its specific implementation is as follows:

[0066] The airborne terminal module 101 receives the following information input: (1) The ADS-B information collection unit 201 collects the aircraft positio...

Abstract

The invention discloses an air traffic control system for four-dimensional (4D)-trajectory-based operation. 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 the monitoring data of an air traffic control radar and automatic dependent monitoring data, and providing real-time trajectory information for the control terminal module; and the control terminal module comprises a preflight conflict-free 4D trajectory generation sub-module, an in-flight short-term 4D trajectory generation sub-module, a real-time flight conflict monitoring and alarming sub-module and a flight conflict resolution 4D trajectory optimization sub-module. The invention also discloses an air traffic control method for the system. The control terminal module processes flight plan data, generates 4D trajectories, analyzes potential traffic conflicts of air traffic conditions and provides an optimal resolution scheme. By the system and the method, flight conflicts can be effectively prevented, and the safety of air traffic can be improved.
