Example Embodiment

[0038] The present invention will be further elaborated and described below in combination with specific embodiments. The technical features of the various implementations in the present invention can be combined accordingly on the premise that there is no conflict with each other.

[0039] like figure 1As shown, the overall process of the present invention is: obtain current flight state estimation based on satellite-based monitoring information, and perform flight trend reasoning, based on the flight trend model and flight flight plan obtained by reasoning, use flight dynamics theory to obtain uncertain multi-factor conditions The flight track of the aircraft in the future will be refined and characterized, and then the rasterized airspace grid will be designed to mark the grids with obstacles, dangerous weather, and other special airspace with time and space restrictions. The prediction result of aircraft flight path calculates the space-time probability distribution in th...

Abstract

The invention discloses a space-time probability distribution grid flight conflict detection method based on flight trend reasoning. Aiming at the problem that various uncertain factors such as meteorological change, air route dynamic adjustment, pilot operation and the like interfere with the movement of an aircraft, the method disclosed by the invention reveals an air traffic flow time-varying rule in combination with trend reasoning and dynamics theories on the basis of obtaining current air state estimation; and furthermore, space-time probability distribution calculation is performed on a rasterized controlled airspace through construction, so that efficient detection among multiple aircrafts and between the aircrafts and the airspace in a complex airspace environment is realized. The stability and robustness of track refinement characterization under uncertain multi-factor common disturbance are improved, and the method has important significance in improving air traffic operation efficiency and guaranteeing air operation safety.

Description

technical field [0001] The invention belongs to the field of aircraft flight trend judgment and conflict detection, and in particular relates to a flight conflict detection method based on flight trend reasoning and space-time probability distribution grid. Background technique [0002] With the continuous improvement of the economic and social level, the demand for air transport continues to increase due to its flexible, efficient and convenient features. The ever-increasing demand for air transportation has brought about a continuous increase in air traffic flow. On the one hand, it increases the risk of aircraft conflicts. On the other hand, it also leads to more congested flight routes and more serious flight delays, which in turn reduces the operational efficiency of the air traffic system. Therefore, it is always the development of the aviation industry to constantly explore the application of new technologies and methods in air traffic management, to detect potential ...
