Grading method for atmospheric pollutants above road

Abstract

The invention discloses a method for grading atmospheric pollutants above roads. The method comprises the following steps: S1, collecting atmospheric pollutant data above each road in real time; s2, calculating distribution values of various atmospheric pollutants above each road within a set time; s3, dividing atmospheric pollutants of the same type in a certain area into N levels according to the size of atmospheric pollutant data; and S4, enabling the atmospheric pollutant data above each road to correspond to the data range of each grade to obtain the final grade of the atmospheric pollutants above each road, and storing related data. According to the invention, the grade data range is dynamically set, accurate positioning of pollutants and pollution sources is realized, and a basis isprovided for timely pollution treatment.

Description

technical field [0001] The invention relates to the technical field of air pollutant monitoring, in particular to a method for grading air pollutants above roads. Background technique [0002] At present, there are roughly two types of pollution monitoring of particulate matter (PM2.5\PM10\TSP) in the air above roads on the market. The first fixed station mode, that is, the micro station and standard station mode, is based on the fine management mode of the atmospheric grid. Fixed stations need to be densely distributed, but standard stations are expensive, and micro stations are difficult to cover all parts of the city. The second vehicle-mounted navigation mode, vehicle-mounted navigation generally uses large-scale equipment, which is expensive and directly restricts the number of urban navigation equipment. [0003] According to the national pollutant discharge standard, the classification of pollutants is based on the average value of pollutants, which belongs to the da...

[0003] According to the national pollutant discharge standard, the classification of pollutants is based on the average value of pollutants, which belongs to the data range of the discharge standard. In this way, the heavily polluted area and the lightly polluted area may be averaged to the moderately polluted area, which cannot be accurately located. pollution source
