Problems solved by technology

[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 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

specific Embodiment 1

[0037] A method for grading air pollutants above roads in this application uses adaptive color scales to mark the distribution of pollutants, such as figure 1 shown, including the following steps:

[0038] S1. Real-time collection of air pollutant data over each road;

[0039] S2. Calculate the distribution value of various air pollutants over each road within the set time;

[0040] S3. Divide the air pollutants of the same type in a certain area into N levels according to the size of the air pollutant data;

[0041] S4. Corresponding the data of air pollutants above each road with the data ranges of each level, obtaining the final classification of air pollutants above each road, and storing relevant data.

[0042] In step S1, the vehicle-mounted air quality sensing equipment is used to monitor the air pollutant data over each road in real time.

[0043] In step S3, N is a positive integer greater than or equal to 2.

[0044] In a specific embodiment of the present applic...

specific Embodiment 2

[0061] A detection and alarm system for particulate pollutants in the air above the road of the present invention, such as figure 2 As shown, including at least one vehicle-mounted air quality sensing device, fixed micro-station detection device, data processing center, and display device, the data processing center collects air quality data detected by all vehicle-mounted air quality sensing devices, public air quality data, Meteorological data and fixed micro-station data are processed to obtain the range of pollutant data, combined with the location of the vehicle-mounted air quality sensing equipment and the location of the fixed micro-station, the distribution of pollutants is displayed in real time to realize dynamic monitoring of air quality.

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.
