AI Technical Summary

Technical Problem

Existing technologies struggle to achieve unified fusion and accurate perception and prediction of multi-source data on low-altitude micro-meteorology, resulting in poor spatiotemporal interpretability and low prediction accuracy in low-altitude flight safety risk assessments, failing to meet the refined requirements at the meter and minute levels.

Method used

A refined low-altitude micro-meteorological sensing and prediction method is adopted. By constructing a spatiotemporal code, and combining the underlying surface data and building elevation data of the specified GeoSOT level for grid identification and modeling, grid cells are formed to associate meteorological data and topographic data. The rule-based decision function is used to predict micro-meteorological events, and the influence of neighboring grids is calculated to construct a low-altitude meteorological grid knowledge graph model.

Benefits of technology

It enables rapid and precise forecasting of low-altitude micro-meteorology, improves the efficiency of spatiotemporal data positioning and calculation, enhances the accuracy of meteorological impact calculation and prediction accuracy, and meets the needs of low-altitude flight safety assessment.

Abstract

The invention discloses a low-altitude micrometeorology refined perception prediction method, which relates to the technical field of meteorological perception, adopts space-time integrated 4D coding, can perform unit meteorological grid indexing on time and space positions of grids in near real time, can perform rapid grid element merging, and can greatly improve time and latitude positioning and calculation efficiency. On the basis of 4D space-time coding algebra, meteorological time sequence evolution influence changes are rapidly calculated through time coding; through spatial coding, the spatial neighborhood, position and orientation relation between the low-altitude meteorology and the airspace is rapidly calculated; the low-altitude meteorological grid chart can be subjected to discretization expression based on low-altitude meteorological elements and topographic data in a space-time grid, and perception prediction of low-altitude micrometeorology is carried out based on meteorological rules; through three-dimensional dynamic meteorological expression of time coding, each meteorological related element is associated with a 4D space-time grid, and rapid prediction of low-altitude micrometeorology is realized based on binary operation advantages of time coding and space coding.
