AI Technical Summary

Technical Problem

In air traffic control, as the number of aircraft increases, it is difficult for the existing technology to quickly and effectively detect and eliminate route conflicts, resulting in inefficient airspace control. Especially when large batches of aircraft influx, conflict dissipation takes too long to form a conflict-free aircraft planning scheme within a limited time.

Method used

Consistent spatiotemporal analysis is used to establish a conflict detection model, build an experience knowledge base for conflict resolution, combine Monte Carlo tree search and focus branch reduction method, search for feasible solutions through Monte Carlo tree search and focus branch reduction method, quickly locate core conflicts and cut conflict tree nodes, and realize conflict-free planning between routes.

Benefits of technology

It realizes rapid conflict detection and dissolution of aircraft routes under the established road network structure, reduces the search scale while ensuring the optimality of results, and improves airspace control efficiency and flight safety.

Abstract

The present invention discloses a method for detecting and quickly resolving aircraft route conflicts under a given road network structure. The method can be based on the given road network structure, through a consistent spatiotemporal analysis method, taking into account the constraints within the road network, and establishing a conflict detection model from several aspects such as same-direction pursuit, reverse intersection, and channel saturation, thereby achieving the qualitative detection of conflicts between multiple aircraft routes; and based on the conflict detection results, a conflict tree is constructed, and through a Monte Carlo tree search and focused branch reduction method, a feasible solution for the route conflict resolution adjustment scheme is searched, thereby achieving the generation of conflict-free route adjustments for multiple aircraft. The present invention detects the routes planned between aircraft, discovers possible collision risks in advance, and provides a fast and feasible route adjustment scheme to resolve conflict risks, thereby achieving conflict-free route planning for a large number of aerial aircraft under a given road network structure.
