Embodiment Construction
[0032] In order to facilitate the understanding of those skilled in the art, the following description of the present invention will be further described with reference to the drawings, and the contents mentioned in the present invention are not limited.
[0033] Refer figure 1 As shown, a method of monitoring processing based on a grid 5D data model, steps are as follows:
[0034] 1) Method for grid mode and grid digital encoding of airport scenes and nearby air spaces with 3D global latitude and latitude margin mesh (GEOSOT-3D) methods;
[0035] Wherein, step 1) specifically includes: dividing the airport scene and near the nearby null domain into a different scale hierarchy, constructing an airport and airspace grid model, encoding each level of grid, The grid network architecture forming the encoding and mesh is formed, forming a new airport scene and nearby airspace organization description method; at this time, each raster unit property only contains 3-dimensional data (long...

The invention discloses an airport scene monitoring processing method based on a grid 5D data model. The airport scene monitoring processing method comprises the following steps: carrying out grid modeling and digital coding on an airport scene and a nearby approaching airspace by adopting a three-dimensional global latitude and longitude grid subdivision method; performing grid modeling and digital numbering on the airport elements, and establishing a mapping corresponding relation with grid codes; time and service attribute marking assignment is carried out by taking airport elements as units, and then airport element grid attributes are extended from three dimensions to five dimensions; and carrying out fusion optimization processing on the multi-source monitoring data based on the airport grid five-dimensional data. According to the invention, the method achieves the refinement, structuring, accuracy and completeness of airport scene data, achieves the setting automation of partial data, provides more stable, reliable and precise scene target monitoring reference information for control tower controllers, and improves the safety and efficiency of scene operation.
Description
Technical field [0001] The present invention belongs to the field of airport scene control technology, specifically refers to an airport scene monitoring process based on a grid 5D data model. Background technique [0002] In order to ensure airport scene aircraft, vehicle operation safety, efficiency, order, and tower controllers require airport scene control systems to provide accurate, stable, reliable airport scenes, target (aircraft, vehicles) operational monitoring, conflict risk warning, etc. Information for safe and efficient command management, such as advanced scene guidance and control system (A-SMGCS), the airport scene of the tower control automation system monitoring data processing processing accuracy, stability, reliability, except for high quality monitoring source signals To a large extent, depending on the airport scene and the perfect, accuracy, refinement, structured, structured, so that it ensures the accuracy of multi-source monitoring data fusion parameter...
