Embodiment 1

[0147] like Figure 5 As shown, a certain aircraft takes off from the airport P 5 To landing airport P 0 There are 6 fixed points on the route, and the fixed points of the route are numbered in sequence from the landing airport to the departure airport: P L ={P 0 ,P 1 ,P 2 ,P 3 ,P 4 ,P 5}. These 6 fixed points divide the route L into 5 flight segments.

[0148] P i point to P 0 The point time is:

[0149]

[0150] Where: s is P i point to P 0 point distance; V i is P i point to P 0 the corrected velocity of the point;

[0151] with P 0 point at T t The mobile time slot node is generated at any time as the reference, and the calculation of P i The timing of point generation mobile slot node is:

[0152] T i =T t +E i modΔt (2)

[0153] P i point at T i The 6-digit identifier of the mobile slot node generated at any time is:

[0154]

[0155] Among them, T t is the current moment, E i for P i Point reaches P 0 point time; Δt is the time inte...

Abstract

The invention discloses a moving time slot air traffic control method based on a 4D flight path. A moving time slot model is established; modern computer, network technology, big data processing technology and the like are applied; a large amount of calculation and prediction in flight control work are realized by a computer system, a visual moving time slot model is provided for a tower flight controller, and a previous control mode depending on artificial mental calculation, visual inspection judgment and manual guidance command is changed into a global (whole flight process)-oriented visualtime slot allocation control mode. When the mobile time slot management method is used in a military and civil aviation radar control system, the flight deployment difficulty can be greatly reduced,errors caused by human factors are reduced, and the control automation level is improved.

Description

technical field [0001] The invention belongs to the technical field of air traffic control methods, and relates to a mobile time slot air traffic control method based on 4D track. Background technique [0002] The 4D track is an accurate description of the spatial position (longitude, latitude, altitude and time) of each point of an aircraft in the form of space and time, and it is the four-dimensional space coordinates of all sequential points experienced by the aircraft. formed collection. Trajectory based operation (TBO--Trajectory based Operation) refers to the use of "controlled arrival time" on the waypoints of the 4D trajectory, that is, the "time window" for controlling the aircraft to pass through a specific waypoint. [0003] With the continuous development of 4D trajectory prediction technology, various trajectory prediction systems have come out one after another and successfully conducted verification flight tests. CTAS (Center-TRACON Automation System, Approa...
