Embodiment Construction

[0038] The present invention will be further elaborated and described below in conjunction with the specific embodiments. of the various embodiments of the present invention

[0051]

[0052] Secondly, the ADS-B information report includes a target status report (TS) and a track change report (TC). TS contains fly

[0060] For example, there are waypoints such as P1, P2, P3... in the original plan. Assuming a combination of flight models based on the flight plan

[0067] When the track is calculated, the model changes of the three dimensions are integrated to form a transition model. Leverage motion models, trends

[0071] Further, in a preferred embodiment of the present invention, considering that the aircraft maneuver is also subject to pilot operation,

[0072] Since the aircraft is constrained by control during flight, the altitude change is relatively stable during cruise. So just assume

Abstract

The invention discloses a grid flight conflict detection method based on flight trend reasoning in space-time probability distribution. Aiming at the problem that various uncertain factors such as meteorological changes, route dynamic adjustments, and pilot operations interfere with aircraft movement, the present invention reveals the time-varying law of air traffic flow on the basis of obtaining current air state estimation, combined with trend reasoning and dynamics theory , and further by constructing the space-time probability distribution calculation of the grid-controlled airspace, the efficient detection between multiple aircraft and between aircraft and airspace in the complex airspace environment is realized. The method of the present invention realizes the advantages of the traditional dead reckoning model Complementary, it improves the stability and robustness of the refined representation of the trajectory under the joint disturbance of uncertain multi-factors, which is of great significance for improving the efficiency of air traffic operations and ensuring the safety of air operations.

Description

A Grid Flight Conflict Detection Method Based on Flight Trend Reasoning technical field The invention belongs to aircraft flight trend judgment and conflict detection field, be specifically related to a kind of based on flight trend push A rational space-time probability distribution grid-flight collision detection method. Background technique With the continuous improvement of economic and social level, air transportation is not required to be demanded because of its flexible, efficient and convenient characteristics. stop improving. The growing demand for air transport has brought about a continuous increase in air traffic flow, which on the one hand has increased the impact of aircraft. On the other hand, it also leads to more congested flight routes and more serious flight delays, thereby reducing the air traffic system operating efficiency. Therefore, the application of new technologies and new methods in air traffic management is continuously explored, and th...
