However, when the rolling time-domain strategy is used in this study, the setting of parameters has great variability. Only by selecting appropriate and appropriate parameters can an optimized path be obtained, which makes the results of this study contingent, and the algorithm needs to be strengthened The stability of [Clare G, Richards A, Sharma S.

Embodiment Construction

[0037] Please refer to figure 2 As shown, in view of the increasingly complex status of airport surface operations, in the process of aircraft taxiing, the implementation process of seeking the optimal taxiing path with the shortest taxiing path and avoiding conflicts can be divided into the following five steps:

[0038] step 1:

[0039] (1) Analyze the airport surface operation mechanism and simplify the network structure of the aircraft taxiing system

[0040]The taxiway plays an important role in the surface operation system. It connects the runway system and the parking stand system, and is one of the important resources of the airport movement area. Carry out initial planning and path optimization for the taxiway path planning system, mainly formulate and optimize the taxiing strategy of aircraft operating on the airport activity area including the runway system, taxiway system and parking stand system as the main body. Now these three systems are abstracted into a ge...

Abstract

The invention discloses a taxiway path optimizing method based on collision detection. In the sliding process of an aircraft, possible cross point collisions, butt collisions and rear-end collisions are detected, and a sliding path is optimized through an improved A* algorithm on the basis of avoiding the collisions. According to the method, the collision problems possibly happening to the aircraft in the sliding process are fully considered, the collisions are avoided, on the premise of guaranteeing safety, the aim of the shortest sliding path is achieved, and then the airport surface running efficiency is improved.

Description

Technical field: [0001] The invention relates to a taxiway path optimization method based on conflict detection, which belongs to the technical field of civil aviation. Background technique: [0002] With the rapid development of my country's civil aviation industry, the number of airport runways has increased, and the path of aircraft ground operations has become increasingly complex. Taxiways are key resources for airport surface operations. Reasonably planning the taxiing path of the aircraft and avoiding possible conflicts during the taxiing process are of great significance to ensure the safety of the aircraft taxiing and the smooth take-off and landing of the flight. Therefore, taxiway path optimization based on conflict detection is one of the important contents of airport surface operation planning. [0003] The current research on airport surface operations is mostly biased towards the optimal scheduling of runways and reasonable allocation of parking spaces, using...
