Aircraft airspace judgment method and device, electronic equipment and medium

Abstract

The invention discloses an aircraft airspace judgment method and device, electronic equipment and a medium. The method comprises the following steps: determining an airspace boundary and a no-fly zone boundary; making a ray in any direction by taking the position of the current aircraft as an original point, and respectively determining intersection points between the ray and the airspace boundary and between the ray and the no-fly zone boundary; and performing parity judgment according to the number of the intersection points, and determining the airspace where the current aircraft is located. The accuracy of judging whether the aircraft flies in the specified airspace or not and the timeliness of early warning are improved, the accuracy is high, and the application range is wide.

Description

technical field [0001] The present invention relates to the field of aircraft flight control, and more specifically, relates to an aircraft airspace judgment method, device, electronic equipment and medium. Background technique [0002] With the rapid increase in the types and numbers of various types of aircraft such as low-altitude small aircraft, medium-high altitude large UAVs, and near-space airships, UAV operations, civil aviation transportation, and military flights are mixed operations, flight conflicts are intensifying, and the airspace environment is becoming more and more complex. This increases the coordination task of airspace control and reduces the effective utilization of space resources. It is necessary to improve the consciousness of aircraft flying in the specified airspace to avoid air traffic accidents. [0003] Airspace is a certain range of space delineated according to the needs of flight training and combat, and the airspace boundaries and no-fly zon...

AI Technical Summary

Problems solved by technology

The airspace safety boundaries of general aircraft may include national boundaries, civil aviation routes, densely populated areas, mountains, military restricted areas, electromagnetic sensitive areas, bad weather areas, etc. The available airspace and restricted airspace vary from place to place, and any aircraft needs to be combined with local Airspace conditions Plan the flight route in advance, and at the same time, it is necessary to judge the airspace position of the aircraft in real time. If it flies out of the specified airspace or into the no-fly zone, it may have a relatively bad impact, and even lead to international disputes or seriously endanger the safety of people's lives and property.

At present, most aircraft judge whether they are in the specified area through the human-in-the-loop, and the consciousness of the aircraft flying in the specified airspace is completely determined by the aircraft operator; the automatic judgment method is realized by comparing the current position with the boundary coordinates. In a simple single-connected area, when flying in a complex multi-connected area, the existing automatic judgment method cannot accurately judge whether to fly into a no-fly zone, and there is a huge potential risk in the arbitrariness of people in the loop
