Embodiment Construction

[0021] see figure 1 , figure 2 It can be seen that a method for realizing ACAS conflict detection in an air traffic control ATC system includes a communication data processing server, a monitoring data processing server, a flight data processing server, a seat workstation and a network device of a support system; the method comprises the following steps:

[0022] (1) Obtain radar real-time surveillance data;

[0023] (2) Carry out tracking filtering, smoothing and interpolation to the position of the acquired monitoring data;

[0024] (3) Select an aircraft, determine its flight range, and select a threat target within the flight range; calculate the slant distance, relative speed, altitude difference, and horizontal distance of the threat target relative to the selected aircraft; generally, the threat is within 50 nautical miles. target selection flight target;

[0025] (4) Threshold value selection, according to the height of the threat target, use the threshold value ta...

Abstract

A method for realizing ACAS conflict alert in a blank pipe ATC system is disclosed. A system is supported by a communication data processing server, a monitoring data processing server, a flight data processing server, a seat work station and network equipment. The method comprises the following steps: (1) acquiring real time radar monitoring data; (2) carrying out tracking filtering, smoothing and interpolation to a position of the obtained monitoring data; (3) selecting an aircraft, determining a flight scope and selecting a threat object in the flight scope; (4) selecting a threshold, using a threshold table to obtain the three thresholds of corresponding reserved time, a horizontal spacing and a vertical spacing according to a height of the threat object; (5) calculating a conflict alert parameter, which comprises an approach speed calculation and a reserved time calculation; (6) calculating alarm. In the invention, through the ATC system, ACAS alarm means encountered by a pilot can be know. A relief measure which is not consistent with the ACAS can be timely corrected. Therefore, hidden troubles can be eliminated and security of air traffic can be increased.

Description

technical field [0001] The invention relates to the field of air traffic management, in particular to a method for realizing ACAS conflict detection in an air traffic control ATC system. Background technique [0002] In air traffic management, the automatic ATC system of air traffic control obtains the real-time monitoring information of the aircraft through radar and other monitoring means, so that the controllers on the ground can judge and grasp the air traffic situation in time. Vertical, horizontal and longitudinal separation to avoid potential collision hazards between airborne aircraft. The potential danger between aircraft in the air is also called flight conflict, and the technology to judge whether there is a conflict between aircraft is called conflict detection; after the conflict occurs, the measure to make the aircraft out of the danger of collision is called conflict resolution. [0003] Collision detection can usually be realized by air traffic control autom...
