Wherein PM10And PM2.5The analytical precision of (a) is as fine as 0.001mg/m3The monitoring precision of sulfur dioxide, nitrogen oxide and ozone can reach 1ppb, and the monitoring precision of carbon monoxide reaches 0.1 ppb; the big data platform supporting module is arranged on the monitoring vehicle and used for calculating pollutant discharge amount of pollutants according to a prestored expansion model, the meteorological data and the pollutant ground concentration so as to calculate the pollutant diffusion range; and the data transmission and display module is arranged on the monitoring vehicle and is used for displaying the obtained video image, the ground concentration value of the pollutant and the pollutant diffusion range.
It should be noted that the video image collected by the video collection module can also be transmitted to the data transmission and display module through the wireless data transmission system, in this case, the data transmission and display module becomes the "display module" actually.
In a first embodiment, an environment monitoring module of the invention first performs analog-to-digital conversion on an analog signal of the ground concentration of the pollutant obtained by a sensor to obtain data of the ground concentration of the pollutant; then, inputting the data into a diffusion model in a big data platform module so as to calculate the pollutant discharge amount; the extent of contaminant diffusion can then be obtained by taking measurements at different locations.

Fig. 7 shows the structure of the highest contamination concentration unit, which includes: the detection module is used for detecting the ground concentration of the pollutants output by the current environment monitoring module to obtain a detection value when the ground concentration of the largest pollutants is known; and the storage module is used for storing the detection value when the detection value is greater than the known maximum pollutant ground concentration and taking the detection value as the next known maximum pollutant ground concentration.
The detection module of the highest pollutant concentration unit detects the current pollutant ground concentration by using the known maximum pollutant ground concentration, and continuously updates the known maximum pollutant ground concentration, namely, the latest maximum pollutant ground concentration replaces the past value, so that the highest pollutant ground concentration is always stored.
Typically, the big data platform support module utilizes the average wind speed U at the original discharge height on the ground, the horizontal lateral spread parameter σ perpendicular to the average wind direction, obtained from the meteorological monitoring moduleyInitializing the lateral spread parameter sigmayVertical spread parameter sigmazEffective height H without tissue contaminationeAnd calculating the pollutant discharge amount Q from the pollutant ground concentration value C obtained by the environment monitoring module.

The synthesis unit adds the pollutant ground concentration value extracted from the environment monitoring module and the geographic data to the video image collected by the video collection module.

The built-in algorithm module can perform traceability analysis on pollutant diffusion, and obtains information such as pollutant diffusion basic conditions and the like by performing reverse thrust on the model, and the method takes a Gaussian diffusion model as an example for explanation:
the Gaussian diffusion mode is the atmospheric pollutant diffusion mode which is most widely applied, most fully verified and most deeply expanded at present. The core idea is that in the process of transmitting the atmospheric pollutants along the wind direction, the atmospheric pollutants are subjected to Gaussian statistical distribution in the vertical direction and the horizontal direction. According to the basic form of the Gaussian model, under windy weather conditions, the concentration of the surface pollutant in the downwind direction of the non-point source can be calculated according to the following formula:
performing reverse-pushing on the formula (1), namely taking the concentration C as an independent variable and taking the pollutant discharge Q as a dependent variable; meanwhile, the concentration C is considered to be on the average wind direction axis, i.e., Y is 0. The gaussian back-stepping mode is obtained as follows:
in the formula: c-ground concentration of contaminants, mg/m3；
Q is the pollutant discharge amount per unit time, mg/s;
y is the vertical distance m between the ground concentration point and the average wind direction axis passing through the pollution source on the horizontal plane;
