Air pollution tracing method and device, computer equipment and storage medium

Abstract

The invention relates to an air pollution tracing method and device, computer equipment and a storage medium. The method comprises the steps of processing historical air quality data based on a Gaussian process regression algorithm, and determining related air stations corresponding to the air stations and meeting related conditions; carrying out matrix processing on the quality data at the tth moment and the air quality data at the (t-1) th moment to obtain a diffusion matrix of the polluted air station at the tth moment; correcting the diffusion matrix according to the geographic position information of the polluted air station at the tth moment, the geographic position information of the related air station of the polluted air station at the tth moment, the wind speed at the t-1 momentand the wind direction at the t-1 moment; and obtaining a decision matrix of the polluted air station at the t-th moment according to the corrected diffusion matrix, and determining the pollution source air station of the polluted air station at the t-th moment according to the decision matrix, so that the pollution source can be traced back quickly and accurately.

Description

technical field [0001] The present application relates to the technical field of air treatment, in particular to a method, device, computer equipment and storage medium for tracing the source of air pollution. Background technique [0002] With the development of industry, air pollution has become more and more serious, and air pollution control has become one of the environmental problems that need to be solved urgently. At present, the main method of air monitoring is to deploy micro air stations widely in the areas that need to be monitored. The micro-air station monitors changes in air quality, and when the air quality is degraded, preventive measures are taken in time to prevent further deterioration of the air quality. , in the process of implementation, the inventors found that there are at least the following problems in the traditional technology: the traditional technology cannot quickly and accurately find the source of pollution. Contents of the invention [0...
