[0027] In this embodiment, two sulfur dioxide concentration monitoring results are obtained through a set monitoring period, and then the difference between the two monitoring results is used to obtain the sulfur dioxide concentration change value, so as to facilitate the grasp of the change of sulfur dioxide concentration during this period of time, and then facilitate the subsequent comparison with the sulfur dioxide concentration change coefficient to determine whether the monitoring result is accurate.

[0028] In the environmental data collection module, the meteorological values ​​within the monitoring range of each monitoring station are obtained, specifically: Step 1: Obtain the current wind speed within the monitoring range of each monitoring station, obtain the wind speed within the monitoring range of each monitoring station one monitoring cycle ago, obtain the wind speed difference by subtracting the current wind speed from the wind speed one monitoring cycle ago, set the wind speed peak preset threshold, and obtain the wind speed reference difference by summing the wind speed peak preset threshold and the wind speed difference; Step 2: Obtain the total rainfall within the monitoring range of each monitoring station within a monitoring cycle up to the current time, and obtain the meteorological value within the monitoring range of each monitoring station through the wind speed reference difference and the total rainfall within the monitoring range of each monitoring station; The calculation method of meteorological values ​​is as follows:

Finally, the meteorological value is obtained by combining the wind speed reference difference and the total rainfall, which facilitates the subsequent calculation of the sulfur dioxide concentration change coefficient based on the meteorological value.

Finally, the total number of fires, the total number of volcanic eruptions and the total coal consumption are used to obtain the impact value within the monitoring range of each monitoring station, so as to facilitate the subsequent calculation of the sulfur dioxide concentration change coefficient based on the impact value.

[0034] In the monitoring data screening module, the overall proportional coefficient is obtained by the sulfur dioxide concentration change coefficient of each monitoring station, the sulfur dioxide concentration change value of the monitoring station and the preset threshold of the sulfur dioxide concentration change, which is: Step 1: Obtain the sulfur dioxide concentration change value of each monitoring station, obtain the preset threshold value of the sulfur dioxide concentration change, subtract the sulfur dioxide concentration change value of each monitoring station from the preset threshold value of the sulfur dioxide concentration change to obtain the sulfur dioxide concentration change reference value of each monitoring station, and sum the sulfur dioxide concentration change reference values ​​of all monitoring stations to obtain the sulfur dioxide concentration change reference sum value; Step 2: Obtain the sulfur dioxide concentration change coefficient of each monitoring station, and sum the sulfur dioxide concentration change coefficients of all monitoring stations to obtain the sulfur dioxide concentration change coefficient; Step 3: Obtain the overall proportionality coefficient by dividing the sulfur dioxide concentration change reference value by the sulfur dioxide concentration change coefficient.

[0035] In this embodiment, the overall proportionality coefficient is obtained by calculating the overall environmental sulfur dioxide concentration change of all monitoring stations, so as to facilitate the subsequent judgment of whether the sulfur dioxide concentration monitoring result of each monitoring station is accurate or not according to the overall proportionality coefficient.

[0036] In the monitoring data screening module, the monomer ratio coefficient of each monitoring station is obtained respectively, which is as follows: Step 1: Obtain the sulfur dioxide concentration change value of each monitoring station and obtain the sulfur dioxide concentration change coefficient of each monitoring station; Step 2: Obtain the monomer proportional coefficient of each monitoring station by dividing the sulfur dioxide concentration change value of each monitoring station by the corresponding sulfur dioxide concentration change coefficient.

[0037] In this embodiment, the monomer proportional coefficient of each monitoring station is obtained by dividing the sulfur dioxide concentration change value of each monitoring station by the corresponding sulfur dioxide concentration change coefficient, so as to facilitate the understanding of the correlation between the sulfur dioxide concentration change value monitored by each monitoring station and the sulfur dioxide concentration change coefficient, and then facilitate the judgment of whether the monitoring result of the monitoring station has a large deviation based on the calculation result.

[0038] In the monitoring data screening module, the monitoring stations to be corrected are marked by the overall proportional coefficient and the individual proportional coefficient of each monitoring station, specifically: Step 1: Obtain the overall proportional coefficient, obtain the monomer proportional coefficient of each monitoring station, set the preset fault tolerance threshold of the proportional coefficient, and respectively subtract the monomer proportional coefficient of each monitoring station from the overall proportional coefficient to obtain the monomer proportional difference coefficient of each monitoring station; Step 2: Compare the relationship between the individual proportional difference coefficient of each monitoring station and the preset threshold of proportional coefficient fault tolerance. If the individual proportional difference coefficient of the monitoring station is greater than the preset threshold of proportional coefficient fault tolerance, mark the monitoring station as a monitoring station to be corrected.

[0039] In this embodiment, by comparing the overall proportional coefficient with the monomer proportional coefficient, it is convenient to judge whether the sulfur dioxide concentration monitoring data of the monitoring station has a large deviation, which is beneficial to judge whether the sulfur dioxide concentration monitoring results of the monitoring station are accurate, and it is beneficial to mark the monitoring stations with large deviations in monitoring results, so as to facilitate subsequent correction of the monitoring results of the monitoring station.

[0040] In the historical data correction module, the sulfur dioxide concentration of the monitoring station to be corrected is corrected by the sulfur dioxide historical concentration data of the monitoring station to be corrected, the sulfur dioxide concentration change coefficient of the monitoring station to be corrected and the overall proportional coefficient, specifically: Step 1: Capture the sulfur dioxide concentration one monitoring cycle before the current sulfur dioxide concentration in the sulfur dioxide historical concentration data to be corrected, and define it as the historical sulfur dioxide concentration, obtain the overall proportionality coefficient, and obtain the sulfur dioxide concentration change coefficient of the monitoring station to be corrected; Step 2: The sulfur dioxide concentration change correction value of the monitoring station to be corrected is obtained by multiplying the sulfur dioxide concentration change coefficient of the monitoring station to be corrected by the overall proportional coefficient. The sulfur dioxide concentration correction value of the monitoring station to be corrected is obtained by summing the sulfur dioxide concentration change correction value of the monitoring station to be corrected and the historical sulfur dioxide concentration. The sulfur dioxide concentration correction value of the monitoring station to be corrected replaces the current sulfur dioxide concentration in the atmosphere monitored by the monitoring station to be corrected.
