Problems solved by technology
In May 2017, drones were found at Shuangliu Airport and the waterway in Sichuan Province many times, causing many planes to make forced landings at nearby airports, resulting in multiple flight delays and losses of tens of millions of yuan
The patent "A Method and System for Airspace Management" proposes an airspace management method to solve UAV airspace application and flight filing, which is only for application and filing, and cannot solve the problem of availability of airspace for application

Embodiment 1
[0053] This embodiment provides a method for retrieving directional available airspace based on resource tags and priorities, such as figure 1 shown, including:
[0054] 1. Add resource labels for gridded airspace resources
[0055]The airspace resources are gridded, and the gridding method can adopt the previously applied invention patent CN 109559567A, specifically: calculate the smallest rectangular bounding box of the airspace to be managed; take a vertex of the smallest rectangular bounding box as the starting point; take the Draw a line along the latitude direction with the longitude translation points obtained after the starting point is translated with the minimum distance each time, and draw a line along the longitude direction with the latitude translation points obtained after the starting point is translated with the minimum distance each time, and the intersection points of the lines are divided in the airspace to be managed All the drawn rectangles are used as t...

The invention discloses a directional available airspace retrieval method and device based on resource tags and priorities, and the method comprises the steps: carrying out airspace resource griddingon an airspace, and then carrying out the following steps: S1, adding resource tags to gridded airspace resources; s2, describing an airspace use demand; step S3, determining a current airspace use demand, and carrying out available airspace retrieval by adopting an availability checking method, wherein the availability checking method comprises the following steps: mapping the airspace use demandand the resource tag, and determining whether the airspace resource meets the current air demand or not through the matching judgment of the current air demand and the resource tag. According to themethod and device, the available airspace of the current demand can be determined before the airspace planning is started, and the adjustment caused by unavailability after the planning is avoided.
Description
technical field [0001] The invention relates to the technical field of airspace management, in particular to a method and device for directional available airspace retrieval based on resource tags and priorities. Background technique [0002] According to data from the Civil Aviation Administration of China, my country's civil aviation has achieved a total of 552 million passenger trips in 2017, a year-on-year increase of 13%. In 2017, the total passenger turnover of my country's civil aviation was 951.28 billion person-kilometers, a year-on-year increase of 13.5%. This is the 13th year in a row that the scale of my country's civil aviation transportation ranks second in the world. [0003] It is estimated that by 2020, the volume of my country's general aviation industry will more than double that of 2015, with flight time increasing by 156.7%, fleet size expanding by 123.7%, the number of general integrations increasing by 66.7%, and the number of private pilot licenses i...
