Embodiment

[0048] Step 1: Obtain the position information of the aircraft through surveillance radar, GPS, ADS-B and other technologiesp i

[0049] Step 2: Track and filter each aircraft to obtain the filtered position P of the aircraft i and speed V i , the filtering method can use the common α-β filtering or Kalman filtering or interactive multi-mode (IMM) filtering method to obtain a relatively accurate and stable velocity vector.

[0050] Step 3: Calculate the Euclidean distance between any two track pairs: D ij = | P i - P j | = ( x i - x j ) 2 + ( y ...

Abstract

The invention provides a technical method for reducing air control automatic system short term conflict alarm false alarm rate, including the following procedures that: air position parameters of each aircraft are acquired by the navigation monitoring system and projected on a displaying plane of the air traffic control system; the position vector (Pi) and the speed vector(Vi) of the aircraft are acquired; the distance between a pair of aircrafts is calculated, if the distance is less than the short term conflict alarm threshold, following steps are carried out, otherwise aircrafts are considered to be under a safety condition; the position vector difference and the speed vector difference of a pair of aircrafts and the inner product of the position vector difference and the speed vector difference are calculated, if the inner product is less than 0, the conflict alarm is reported, otherwise the two aircrafts are considered have no conflict. The relation of the current ongoing flight and the flight position of the aircraft are comprehensively considered in the invention, thereby lowering the short term conflict alarm false alarm rate and improving the control efficiency of the control system.

Description

technical field [0001] The invention relates to a management method for aircraft flight in an air traffic control automation system, in particular to a technical method for reducing the false alarm rate of short-term conflicts between two or more aircraft. Background technique [0002] In the current field of air traffic control, in order to maintain the flight order of aircraft and ensure flight safety, the decision-making department has formulated strict flight separation standards (State Council / Central Military Commission Air Traffic Control Committee, "Flight Separation Regulations", Civil Aviation Press of China, 2003.3 ): When the flight altitudes of the aircraft flying on adjacent routes are the same or less than the specified altitude difference, the lateral separation shall not be less than 20 kilometers; In case of poor weather, a lateral separation of not less than 10 kilometers should be maintained from the air route boundary. This kind of mandatory regulation ...
