Embodiment 1

[0049] An embodiment of the present invention provides a method for identifying an abnormal area of ​​air pollution, such as figure 1As shown, the method includes:

[0050] S1: The area to be monitored is divided into grids according to a certain size.

[0051] This step divides the grid according to a certain size according to the air pollution grid supervision requirements. Taking Beijing as an example, the whole city of Beijing is divided into grids of 500m×500m, and a grid mapping relationship data set is established, including the grid number, the latitude and longitude information of the four corners of the grid, the grid position, the grid number of the hotspot it belongs to, and the area it belongs to Counties, streets and townships to which the grid belongs, satellite remote sensing data and pollution source distribution data sets in the grid, etc.

[0052] S2: Calculate the hourly pollutant concentration of each grid.

[0053] Taking the pollutant PM2.5 as an exam...

Embodiment 2

[0073] An embodiment of the present invention provides a device for identifying an abnormal area of ​​air pollution, such as image 3 As shown, the device includes:

[0074] The grid division module 1 is used for grid division of the area to be monitored according to a certain size.

[0075] The pollutant concentration calculation module 2 is used to calculate the hourly pollutant concentration of each grid.

[0076] The short-term peak alarm grid identification module 3 is used to calculate the emission characteristics of each grid according to the hourly pollutant concentration of each grid, and compare the emission characteristics of each grid with the pre-established pollution emission characteristic information database Matching is performed to identify short-duration peak alarm grids.

[0077] The hourly peak factor calculation module 4 is used for each hour of each grid to calculate the difference between the pollutant concentration of the grid in this hour and the po...

Embodiment 3

[0092] The method described in the above-mentioned embodiment 1 provided in this specification can implement business logic through a computer program and record it on a storage medium, and the storage medium can be read and executed by a computer to achieve the effect of the solution described in embodiment 1 of this specification. Therefore, the present invention also provides a computer-readable storage medium for identifying abnormal air pollution areas, including a memory for storing processor-executable instructions. When the instructions are executed by the processor, the air pollution abnormal area described in Embodiment 1 is realized. Identify the steps of the method.

[0093]The storage medium may include a physical device for storing information, and usually digitizes the information and then stores it using electrical, magnetic or optical media. The storage medium may include: devices utilizing electric energy to store information, such as various types of memory,...

Abstract

The invention discloses an atmospheric pollution abnormal area identification method and device, a storage medium and electronic equipment, and belongs to the field of atmospheric monitoring. The method comprises the following steps: performing grid division on a to-be-monitored area; calculating the pollutant concentration per hour of each grid, calculating the emission characteristics of each grid, and recognizing a short-time peak value alarm grid according to the emission characteristics; for each hour of each grid, calculating the sum of difference values between the pollutant concentration of the grid in the hour and the pollutant concentration of each surrounding adjacent grid in the hour, calculating the ratio of the sum of the difference values to the pollutant concentration of the grid in the hour, and obtaining a peak coefficient of the grid in the hour; accumulating the peak value coefficients of each grid in all hours within a period of time to obtain the peak value coefficient of the grid; and obtaining a regional peak value alarm grid by taking the grids with the peak value coefficients from large to small by a certain percentage. According to the invention, accurate and real-time identification of the atmospheric pollution abnormal area is realized, and scientization and precision of atmospheric pollution identification are improved.

Description

technical field [0001] The present invention relates to the field of atmospheric monitoring, in particular to a method, device, storage medium and electronic equipment for identifying abnormal areas of atmospheric pollution. Background technique [0002] Air pollution refers to the phenomenon that the concentration of pollutants in the atmosphere reaches a harmful level, so as to destroy the ecological system and the conditions for the normal survival and development of human beings, and cause harm to people and things. Its causes include natural factors (such as volcanic eruptions, forest disasters, rock weathering, etc.) and human factors (such as industrial waste gas, fuel, automobile exhaust and nuclear explosions, etc.). The impact of air pollution on the human body is firstly the feeling of discomfort, followed by a reversible physiological reaction, and further symptoms of acute harm. [0003] Air pollution is very harmful to industrial and agricultural production. T...
