Abstract

The embodiment of the invention discloses a method and a device for tracing air pollutants, equipment and a storage medium. The method comprises the following steps: acquiring traceability data collected by a monitoring point, wherein the traceability data comprises air pollutant data, wind direction data and wind speed data; determining a probability distribution diagram of the air pollutants ona preset wind direction interval according to the traceability data; determining a wind direction and wind speed rose diagram corresponding to the preset wind direction interval according to the winddirection data and the wind speed data; and determining the traceability information of the air pollutants based on the probability distribution diagram and the wind direction wind speed rose diagram.According to the embodiment of the invention, the probability distribution diagram of the air pollutants is combined with the wind direction wind speed rose diagram, so that the problems of large data volume requirement and inaccurate prediction are solved, the accuracy and precision of the traceability result of the air pollutants are improved, accurate data support is provided for law enforcement personnel to control the air environment, and then the law enforcement efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of traceability of pollutants, and in particular to a traceability method, device, equipment and storage medium of air pollutants. Background technique [0002] In recent years, due to the rapid development of social economy, environmental and air pollution problems have become increasingly serious. All parts of the country have been repeatedly attacked by smog. In severe cases, the entire city is surrounded by smog, and vehicles and buildings are hard to see. This has caused social concern about air quality and the environment. Pollution is a strong concern. [0003] In order to effectively promote the implementation of environmental supervision work, the Environmental Protection Bureau has continuously strengthened work measures and actively promoted the construction of a grid-based air quality supervision system. The grid-based air quality supervision system (referred to as the ...
