The server may be implemented by an independent server or a server cluster composed of a plurality of servers.

In one embodiment, the environmental variables include, but are not limited to, a position vector between the incineration site and a detection point, a wind direction vector between the incineration site and the detection point, a wind speed, and an average time for the incineration contaminants to diffuse from the incineration site to the detection point. Wherein, the diffusion time of the incineration pollutants is influenced by the environmental humidity and temperature.

In one embodiment, the detection point comprises a plurality of detection points. It can be understood that for each detection point, the current environment variable between the waste incineration site and the detection point needs to be acquired, and correspondingly, each detection point is provided with an atmospheric pollution detection device for detecting the pollutant detection concentration of the corresponding detection point in real time.

Preferably, the garbage incineration site is used as a center, the detected region, for example, shenzhen, is divided into a plurality of space minimum calculation units with equal areas, and an atmospheric pollution detection device corresponding to the detection point is arranged in the space minimum calculation unit and is used for detecting the pollutant concentration in the space unit in real time.

Further, the geographic space may be partitioned into spatial minimum computation units by using a grid of regular hexagons having a side length of, for example, 500 meters or 1000 meters. The regular hexagon grid has the advantages that the regular hexagons can only divide the geographic space, the distances between the geometric center points of any adjacent regular hexagons are equal, and in the process of representing the geographic space relationship, the difference that the detection point position is influenced by the diffusion rate of the atmospheric pollutants can be reduced to the maximum extent.

And S102, calculating a pollutant diffusion influence value of a corresponding detection point according to the current environment variable.

It is understood that the current environmental variable represents an environmental variable between the waste incineration site and the detection point at the current time, and the pollutant diffusion influence value represents a magnitude of influence of the atmospheric pollutants by the environmental variable, for example, when the wind speed is small, the influence of the atmospheric pollutants generated by the waste incineration site on a region at a certain distance from the waste incineration site is small, whereas when the wind speed is large, the influence of the atmospheric pollutants generated by the waste incineration site on a region at a certain distance from the waste incineration site is large. The influence of the current environmental variable on the pollutant diffusion can be quantified by calculating the pollutant diffusion influence value.

Further, the environmental variables include a position vector between the refuse burning place and the detection point, a wind direction vector, a wind speed, and an average time for burning pollutants to diffuse from the refuse burning place to the detection point, the pollutant diffusion influence value is proportional to a product of the wind speed and the average time, and the pollutant diffusion influence value is inversely proportional to a product of the position vector and the wind direction vector.

Specifically, the pollutant diffusion influence value of the corresponding detection point is calculated by the following formula:

wherein d represents the wind speed, t_nRepresents the average time for the incinerated pollutants to diffuse from the incineration site to the detection point,the position vector is represented by a vector of positions,and the wind direction vector between the incineration place and the detection point is represented.

Further, the pollution monitoring index is calculated by the following first formula:

wherein, J_nExpressing standard coefficient, K expressing the concentration value of the international standard atmospheric pollutant exceeding standard, Y_nThe pollutant diffusion influence value of the detection points n is shown, and x represents the total number of the detection points.

In one embodiment, the step of comprehensively determining whether the atmospheric pollution at the corresponding detection point exceeds the standard or not according to the pollutant detection concentration, the pollution monitoring index and the basic detection value further includes:

confirming the overproof condition of the detection point n by the following second formula:

M_n＝H_n-C_n-S_n (2)

wherein H_nIndicating the actual detected concentration of the pollutant, C, detected by an atmospheric pollution detection device located at detection point n_nIndicating a pollution-monitoring indicator, S, corresponding to a detection point n_nA base detection value, M, representing a detection point n_nThe sign of (1) indicates the superscalar condition of the detection point n, a positive sign indicates superscalar, and a negative sign or 0 indicates no superscalar.

(3) And obtaining the conditional probability distribution of the atmospheric pollution detection devices in the detection points in a preset time period according to the first result and a second result of whether the waste incineration ground emission exceeds the standard or not.

In one embodiment, the conditional probability distribution of the atmospheric pollution detection device in any detection point can be represented by the following table (1).

	The waste incineration ground discharge does not exceed the standard	Waste incineration ground emission exceeds standard
			Detection point validation exceeds standard	Xn	Zn
Check point confirms that the standard is not exceeded	X′n	Z′n

Watch (1)

Wherein, X_n、X′_n、Z_nAnd Z'_nAll represent the number of times, X_nNumber of times Z representing that discharge of refuse incineration site does not exceed standard but detection point confirms that it exceeds standard_nThe emission of the waste incineration site exceeds the standard, the detection point is confirmed to exceed the standard, and the like. Further, whether the emission of the waste incineration site exceeds the standard or not can be detected by a pollution emission monitoring device arranged on the waste incineration site. And the detection point determines whether the emission of the waste incineration site exceeds the standard or not, and the emission is obtained through comprehensive judgment.

(4) And calculating the probability that the emission of the waste incineration site exceeds the standard and the corresponding detection points exceed the standard through comprehensive judgment according to the conditional probability distribution.

(6) And when the emission of the waste incineration site exceeds the standard and the maximum probability of exceeding the standard is confirmed by calculating the corresponding detection point, the standard coefficient corresponding to the maximum probability is obtained, and the obtained standard coefficient is determined as the standard coefficient of the corresponding detection point.

The learning process of the standard coefficients in the embodiment is completed, the atmospheric pollution detection devices distributed at all detection points can share parameter information of other atmospheric pollution detection devices, based on the parameter information, position replacement can be carried out among any atmospheric pollution detection devices, comprehensive judgment on whether the atmospheric pollutants generated in the garbage incineration site exceed the standard or not can be realized only by acquiring the standard coefficients of the corresponding detection points, and the atmospheric pollution detection devices at a certain detection point can be directly replaced when the atmospheric pollution detection devices are in fault.

And S104, calculating a pollution monitoring index of a corresponding detection point according to the pollutant diffusion influence value, the concentration value of the international standard atmospheric pollutant exceeding the standard and the standard coefficient of the detection point.

It is understood that the pollution monitoring indicator is calculated by the first formula:

wherein, J_nThe central processing device automatically adjusts the probability map model according to the probability map model, and the default value of the probability map model is 1. It will be appreciated that the standard factor J for different detection points_nAre generally different, and J of the same detection point under different environment variables_nThe values are generally different.

And S105, acquiring a basic detection value of the detection point under the current environment variable when the waste incineration site has no emission.

When the basic detection value is obtained, after the operation of burning the garbage by suspending the garbage burning is continued for a certain time (for example, one week or one month), the atmospheric pollutant monitoring device arranged at each detection point is used for monitoring and recording the basic atmospheric pollutants, and the atmospheric pollutants in a period of time (for example, one month) are continuously recorded, wherein the atmospheric pollutants use AOI (Automated Optical Inspection) as a main monitoring index, and the monitored atmospheric pollutants include: sulfur dioxide, nitrogen dioxide, PM10, PM2.5, carbon monoxide and ozone, which is automatically recorded by machine learning and a linear regression is completed.

In one embodiment, the step of obtaining a basic detection value of the detection point under the current environmental variable when the refuse incineration is free of emission further comprises:

acquiring all environment variables of detection points and pollutant detection concentrations under the corresponding environment variables when no emission exists in the waste incineration site;

taking each environmental variable as an x value, taking the pollutant detection concentration under the corresponding environmental variable when the waste incineration site is free of emission as a y value, and solving to obtain an a value and a b value in a linear regression formula to obtain a linear regression formula, wherein the linear regression formula is expressed as:

y＝ax+b；

and substituting the current environment variable into the linear regression formula to obtain a basic detection value of the detection point under the current environment variable when the waste incineration site has no emission.

In one embodiment, when the waste incineration site is free of emission, the environmental variables of the detection point comprise wind direction, wind speed, humidity, temperature and altitude.

In one embodiment, in order to make the basic detection value of the detection point under the current environmental variable more accurate when the waste incineration is emission-free, the step of taking the pollutant detection concentration under the corresponding environmental variable when the waste incineration is emission-free as the y value further comprises:

acquiring the detection concentration of each first pollutant of different detection points under the same environmental variable when no emission exists in the waste incineration site;

acquiring the detection concentration of each second pollutant of the same detection point under the same environmental variable at different time periods;

and taking the average value of the detection concentration of each first pollutant and the detection concentration of each second pollutant as the detection concentration y value of the pollutant under the corresponding environmental variable when the waste incineration site does not discharge.

When the waste incineration site is free of emission, the detection concentrations of the first pollutants at different detection points under the same environmental variable are obtained, the detection concentrations of the first pollutants at different detection points under different time periods and the detection concentrations of the first pollutants under the environmental variable can be recorded, and the detection concentrations of the first pollutants corresponding to the same environmental variable are compared in recorded data to obtain the detection concentrations of the first pollutants. Correspondingly, the detection concentrations of the second pollutants at the same detection point under the same environmental variable at different time periods can also be obtained by recording the environmental variable at the same detection point at different time periods and the detection concentrations of the second pollutants at different environmental variables in real time, and comparing the detection concentrations of the second pollutants corresponding to the same environmental variable according to the recorded values.

And S106, acquiring the detection concentration of the pollutants detected in real time by the atmospheric pollution detection device arranged at the detection point.

It will be appreciated that the detection point at which the atmospheric pollution detection device is provided may comprise several. Further, the central processing unit (i.e., the server) synchronizes all the atmospheric pollution detection devices, each of the atmospheric pollution detection devices receives geographic position information (GPS/beidou positioning) of the central processing unit, the waste incineration site is used as an origin of a spatial reference coordinate system, the atmospheric pollution detection devices at all the detection points calculate and store spatial position information relative to the waste incineration site, fig. 5 is a schematic diagram of arranging the atmospheric pollution detection devices at the detection points in one embodiment of the present invention, as shown in fig. 5, the first preset value is 1.5 kilometers, as shown in a rectangular planar coordinate system shown in fig. 5, the relative coordinate positions of the atmospheric pollution detection devices are (2, 2), and both the X-axis value and the Y-axis value are 2 kilometers.

S107, comprehensively judging whether the atmospheric pollutants generated in the waste incineration site at the detection point exceed the standard or not according to the pollutant detection concentration, the pollution monitoring index and the basic detection value.

In one embodiment, the step of comprehensively determining whether the atmospheric pollutants generated at the waste incineration site at the detection point exceed the standard or not according to the pollutant detection concentration, the pollution monitoring index and the basic detection value specifically includes:

calculating a difference value between the pollutant detection concentration and the pollution monitoring index according to the pollutant detection concentration detected in real time by an atmospheric pollution detection device arranged at the detection point to obtain a first difference value;

calculating a difference value between the first difference value and the basic detection value to obtain a residual value;

and when the residual value is a positive number, judging that the atmospheric pollution of the waste incineration site exceeds the standard at the corresponding detection point, and when the residual value is a negative number or zero, judging that the atmospheric pollution generated by the waste incineration site does not exceed the standard at the corresponding detection point.

It can be understood that the detected pollutant concentration is the actual concentration of the gas detected in real time by the atmospheric pollution detection device arranged at the detection point, the pollution monitoring index is calculated by the first formula, and the pollution monitoring index represents the gas concentration correction value of the detection point which is definitely corresponding to the gas diffusion after the gas diffusion is influenced by the diffusion of the environmental variable. Because the relative positions of each detection point and the waste incineration site are different and are influenced by wind direction and wind speed, the pollution monitoring indexes of different detection points are generally different. Taking the wind speed as an example, the larger the wind speed is, the smaller the value of the pollution monitoring index is, the smaller the value which needs to be corrected after the actual concentration of the gas (i.e. the pollutant detection concentration) is detected at the detection point is, and conversely, the smaller the wind speed is, the larger the calculated value of the pollution monitoring index is, the larger the value which needs to be corrected after the pollutant detection concentration is detected at the detection point is.

Further, whether the atmospheric pollution of the atmospheric pollutants generated in the waste incineration site at the corresponding detection point exceeds the standard or not is calculated through the first formula. And the standard coefficient in the first formula is the optimal standard coefficient obtained by enumeration and screening.

In one embodiment, the method further comprises:

acquiring an atmospheric pollution concentration value of a corresponding waste incineration site sent by a pollution emission monitoring device, wherein the distance between the pollution emission monitoring device and the corresponding waste incineration site is smaller than a second preset value;

judging whether the atmospheric pollution of the waste incineration site exceeds the standard or not according to the concentration value of the international standard atmospheric pollutants exceeding the standard and the magnitude of the atmospheric pollution concentration value;

and when the atmospheric pollution of the waste incineration site does not exceed the standard and the atmospheric pollution of the atmospheric pollutants generated in the waste incineration site at the corresponding detection point exceeds the standard, judging that the pollution emission monitoring device arranged in the waste incineration site breaks down.

Wherein the second preset value is, for example, 10 meters, and optionally, the pollution emission monitoring device is set up within 10 meters of the vicinity of the waste incineration site for synchronously monitoring the atmospheric pollution condition of the waste incineration site.

It can be understood that, when the air pollution concentration value of the waste incineration site detected by the pollution emission monitoring device is greater than the value that the international standard atmospheric pollutants exceed, it indicates that the air pollution of the waste incineration site exceeds, and when the air pollution concentration value of the waste incineration site detected by the pollution emission monitoring device is less than or equal to the value that the international standard atmospheric pollutants exceed, it indicates that the air pollution of the waste incineration site does not exceed.

In one embodiment, when the atmospheric pollution of the waste incineration site is judged to be excessive, the method further comprises the following steps:

and sending out early warning reminding, and recording the hours when the atmospheric pollution of the waste incineration site exceeds the standard.

In one embodiment, when the atmospheric pollution of the atmospheric pollutants generated in the waste incineration place at the corresponding detection point is judged to be out of standard, the method further comprises the following steps:

sending out an early warning prompt;
