Airport scene operation simulation method based on cellular automaton

Abstract

The invention discloses an airport scene operation simulation method based on a cellular automaton. The airport scene operation simulation method comprises the following steps of setting an aircraft operation simulation module and a display interaction module; collecting environment information; performing information processing: according to various collected information, an aircraft scene operation model is established through an aircraft operation simulation module, the aircraft operation simulation module outputs aircraft simulation operation data through simulation operation and sends theaircraft simulation operation data to a display module, and a system operation process is reproduced or rehearsed; identifying the problem; analyzing and evaluating; performing measure implementation: obtaining a problem solving scheme by analyzing an evaluation result, making a solution measure by referring to the scheme, and then converting the solution measure into input data change; and repeating the previous steps until the analysis and evaluation result meets the requirement. The airport scene operation program of the aircraft is depicted in detail, the mutual influence of the aircraftduring operation is reflected, and the traffic characteristics of position and speed synchronism, slow start, metastable state and the like during movement of the aircraft are shown in reality.

Description

technical field [0001] The present invention relates to a kind of airport surface operation simulation method, relate in particular to a kind of airport surface operation simulation method based on cellular automata. Background technique [0002] With the rapid development of the air transport industry, the traffic volume on the airport surface is constantly increasing, the scale of the airport is larger, the run-slip structure is more complex, the problems of unsafe operation on the surface, frequent accidents and low operation efficiency are gradually becoming prominent, and the airport is becoming more and more restricting aviation. Bottleneck for further development of transport. Aircraft surface operation simulation is the reproduction and rehearsal of airport surface operation conditions. On October 11, 2016, a Category A runway incursion occurred at Hongqiao Airport in China, which sounded the alarm for the safety of air traffic operations. At present, the simulatio...

Problems solved by technology

[0008] 1. The method of overall overall planning and resource use to calculate the aircraft operation process is quite different from the actual operation process. This kind of operation program that focuses on the overall operation situation and plans the time sequence of each aircraft passing through the critical path must rely on surface surveillance equipment, ground guidance and control equipment (such as A-SMGCS, etc.), but in China, only Beijing Capital Airport and Shanghai Pudong Airport have installed corresponding facilities, and they have not been applied in actual operation; at the same time, part of the overall optimization is based on the shortest theoretical time and the shortest theoretical path. function, so there is a large gap between the given aircraft operation process and the actual control scheme

[0009] 2. The description of the aircraft taxiing process is relatively simple in the traditional taxiing simulation modeling, and the simple kinematics model is used to calculate the aircraft taxiing speed change according to the assigned taxiing path and the time to reach the key crossing

[0010] 3. Although the current surface operation simulation method has established the basic model of the apron operation, there are few studies on the aircraft apron operation process, and most of them are aimed at the allocation of apron resources, conflict detection, energy saving and emission reduction, etc., which have not been reflected in the model The detailed operating status such as speed and position changes in the aircraft ramp operation, and most studies discuss the ramp and the maneuvering area separately, without comprehensive consideration of the launch of the aircraft, the continuity of the taxiing process, and the exit of the aircraft and the taxiing process. There is a certain gap between the research results and the actual operation of aircraft conflict avoidance

[0011] 4. The simulation visualization and display tools currently used are complicated to use, the modeling process is long, and some platforms have limited open interfaces. After the road network is established, dynamic changes cannot be realized, and some dynamic random events (control instructions, pilot intentions, etc.) are difficult to reproduce
