Abstract

A clustering device is provided, comprising: an acquisition unit configured to acquire monitoring data of monitoring points, the monitoring data being spatiotemporal data; a dividing unit configured to select target data from the acquired monitoring data, and to The selected target data is divided into levels; a construction unit is configured to construct a clustering parameter according to the divided target data; and a determination unit is configured to determine the category of the monitoring point according to the clustering parameter. A clustering method is also provided. By adopting the present invention, the correlation of temporal and spatial changes between monitoring points can be obtained. As far as air pollution monitoring data is concerned, pollution nodes with similar pollution transmission links can be obtained, thus realizing pollution source traceability.

Description

technical field [0001] The present application relates to the field of data analysis, and in particular to a clustering device and method. Background technique [0002] The formation of air pollution is affected by factors such as emissions, diffusion conditions, and geographical environment, and its causes are complex and diverse, which makes it difficult to accurately analyze the distribution and diffusion trends of air pollution in a certain area. Especially for the traceability of pollution sources, there is a lack of effective data analysis methods. SUMMARY OF THE INVENTION [0003] The present invention comprehensively considers influencing factors such as atmospheric pollutants, weather, geography, etc., excavates the temporal and spatial correlation characteristics between air pollution monitoring points, and aggregates monitoring points with the same characteristics of pollution changes and diffusion trends. The present invention can be applied not only to air po...
