Airport surface road network model and airport surface collision detection critical alarm algorithm

Abstract

The invention provides an airport surface road network model, wherein an airport aircraft ground moving path is divided into fork components, taxi track components, runway components and taxi track component ports. The invention further provides an airport surface collision detection critical alarm algorithm which comprises the following steps of: for each aircraft, firstly computing the time when the aircraft enters into and leaves away from all the components according to the ground path of the aircraft and the speed of the aircraft; and for each fork component and each taxi track component, determining whether or not the component has a collision risk. After the airport surface road network model and the airport surface collision detection critical alarm algorithm provided by the invention are used, the safety detecting efficiency of an airport can be observably improved, the running instantaneity can be guaranteed, so that the airport surface road network model and the airport surface collision detection critical alarm algorithm provided by the invention are better in stability and robustness.

Description

technical field [0001] The invention belongs to the field of software algorithms, and relates to an airport scene road network model and an airport scene conflict detection critical alarm algorithm. Background technique [0002] The composition of the airport surface traffic system is very complex. There are not only the launching, driving, taxiing, takeoff, and landing of a large number of aircraft, but also the activities of a large number of special service vehicles, equipment and personnel providing ground support operations for aircraft. In order to prevent conflicts and collisions between aircraft operating on the ground, and between aircraft and special vehicles, equipment, and personnel, it is necessary to effectively partition the airport and establish a unified guidance and control of ground activities. The venues available for aircraft operation at the airport include: runways, rapid exit taxiways, taxiways, contact roads, aprons, and low-altitude airspace adjacen...

AI Technical Summary

Problems solved by technology

[0004] Using the collision detection method to study the conflict problem of aircraft on the runway and taxiway, it is easy to ignore the influence of the airport configuration and road network on the trajectory and spatial distribution. Traction regulations and road safety traffic management rules in airport activity areas, etc. Existing technologies cannot handle situations such as rival taxiing deadlocks, and false alarms are prone to occur when waiting to give way at intersections; support from high-precision monitoring signals is required, and the accuracy of conflict detection is too high Rely on the accuracy of surveillance target positioning, poor system stability and robustness
