Embodiment 1

[0147] Such as 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 i...

Abstract

The invention discloses a mobile time-slot aviation control method based on 4D track, establishes a mobile time-slot model, uses modern computer, network technology and big data processing technology, and performs a large number of calculations and predictions in the flight control work by the computer system to provide a visual mobile time slot model for tower flight controllers, and change the previous control mode that relied on human mental calculation, visual judgment, and manual guidance and command into a global (full flight process) and visualized time slot allocation control model. The use of mobile time slot management methods in military and civil aviation radar control systems can greatly reduce the difficulty of flight deployment, reduce errors caused by human factors, and improve the level of control automation.

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...
