A conflict-free trajectory planning method, device and system based on reachable space-time domain

Abstract

The embodiment of the invention discloses a conflict-free track planning method, device and system based on the reachable space-time domain, which relates to the technical field of air traffic management and planning, and helps to improve the flight safety of aircraft in the four-dimensional track operation mode and reduce the controller workload. The invention includes: collecting the flight data of the aircraft in the cruising operation stage, and recording the real-time position and planned track of the aircraft in the cruising operation stage in the three-dimensional space-time coordinate system; The aircraft’s accessible space-time domain and the intruding aircraft’s oblique cylinder protection zone; the intersection of the accessible time-space domain and the intruding aircraft’s oblique cylinder protection zone is projected onto a two-dimensional plane to obtain a set of conflict diversion points; the conflict diversion point The set of is removed from the reachable space-time domain projected by the main aircraft on the two-dimensional plane, and a set of conflict-free diversion points and a conflict-free feasible diversion track can be generated. The invention is applicable to air traffic management.

Description

technical field [0001] The invention relates to the technical field of air traffic management and planning, in particular to a conflict-free track planning method, device and system based on reachable space-time domain. Background technique [0002] With the rapid development of my country's air transport industry, the contradiction between the increasing demand for airspace utilization and the shortage of real airspace resources has become increasingly prominent, and the phenomenon of airspace congestion and flight delays has become increasingly serious. The operating mode can no longer meet the needs of future development. [0003] In order to solve the problem of shortage of airspace resources and improve the utilization rate of existing airspace resources, our country has begun to turn its attention to the new operation mode based on trajectory, and has carried out successful test flights. Facing future large-scale and high-density trajectory operations, it is urgent to ...

Problems solved by technology

[0004] At present, in the theoretical research based on trajectory operation, the research results of trajectory prediction and trajectory uncertainty are relatively rich, but the existing results are mainly biased towards the pre-tactical level, and there is no real-time and effective solution to solve the actual flight problems in the airspace method

In addition, the existing track models have defects such as complex modeling process, difficult mathematical solution, and low degree of visualization, and it is difficult to integrate them into a system tool that can provide auxiliary decision-making for controllers to resolve conflicts.

[0005] As a result, controllers still mainly rely on manual experience when making trajectory tactical allocation decisions, which requires high skill requirements and heavy workload, which is especially likely to affect the safety and efficiency of dense trajectory operations.
