Automatic identification system and identification method for atmospheric pollution emission source

Abstract

The invention discloses an atmospheric pollution emission source automatic identification system, which comprises a system platform, and is characterized in that the system platform comprises a data storage module, a timing task scheduling module, a data downloading module, a data pre-processing module, a meteorological numerical prediction model, an atmospheric pollution air mass diffusion impression prediction model, a data post-processing module and a judgment control module; the data storage module is in interactive connection with the data post-processing module and the judgment control module. According to the system and method, efficient and automatic forecasting of the atmospheric pollution air mass source is achieved, spatial analysis is automatically carried out on the atmospheric pollution air mass source and the emission source information, the emission source which plays a leading role in atmospheric pollution events is quickly and automatically screened and identified, accurate identification of key pollution sources is achieved, and automatic control suggestions are output; faults generated in the manual operation process are avoided, the work intensity of evidence obtaining and source control is reduced, and scientific bases and decision support are provided for ecological environment and meteorological departments to formulate scientific countermeasures.

Description

technical field [0001] The invention relates to the research field of air pollution source identification technology, in particular to an air pollution emission source automatic identification system and identification method. Background technique [0002] In recent years, my country's rapidly developing urban agglomerations have entered a new stage of comprehensive prevention and control of air pollution. It is necessary to further accelerate the transformation of my country's air pollution prevention and control strategies, and put forward new technical requirements for regional air pollution control and continuous improvement of air quality. . The sources of air pollutants mainly include local emission and exogenous transportation. Under unfavorable diffusion meteorological conditions, air pollutants can accumulate at low altitudes, resulting in air pollution events. Quickly screening and identifying emission sources that play a leading role in the occurrence of air pollu...

Problems solved by technology

[0004] At present, the numerical model method based on the theory of atmospheric physics and atmospheric chemistry is applied to the identification method of air pollution emission sources by scholars at home and abroad. Although this type of method can reduce the scope of surveying enterprises of polluting on-site surveying personnel to a certain extent, it still requires more manpower and time investment to find the source of pollution due to its massive output results.
