Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

The pollutant control scheme provided by the embodiment of the application is mainly divided into two parts of prediction control and real-time control. The prediction control refers to controlling pollutant emission in a future period of time in a target area according to the prediction of the pollutant concentration; real-time control refers to controlling the current real-time pollutant emission according to the pollutant concentration observed in real time. The following describes the prediction control and the real-time control in sequence.

Referring to fig. 1, fig. 1 is a flowchart of a prediction control method according to an embodiment of the present application, where the prediction control method may include the following:

step S101: and acquiring the transmission contribution concentration and the local contribution concentration of the target national control station.

Step S102: and judging the transmission contribution concentration and the local contribution concentration.

Step S103: if the transmission contribution concentration is smaller than the local contribution concentration, providing a global management and control scheme; otherwise, a neighborhood management and control scheme is provided.

Specifically, for a preset area range, the area range can be divided into a plurality of grids (the size of the grids can be determined according to actual conditions), wherein a national control station (the number and the position of the national control station can be determined according to actual conditions) is arranged in part of the grids, and the national control station is used for observing the pollutant concentration, the wind speed and other data of the grids. That is, for a predetermined area, the data relating to the contaminant may include two parts: pollutant observation data observed by the national control station and pollutant emission amount of each grid obtained by statistics and coordinates of the grids.

As an embodiment, the preset area range may have various implementations, for example: one city is a preset regional range; or, an administrative area is a preset area range, etc., which is not particularly limited in the embodiment of the present application.

Among other things, it is understood that there are various ways for the electronic device to obtain the above-mentioned data related to the contaminant, for example: receiving data sent by other devices; or directly reading the stored data from the cloud database, etc., which is not particularly limited in the embodiment of the present application.

After obtaining the data related to the pollutants, the pollutant concentration of a certain national control station (named as a target national control station for convenience of description) in a future period of time can be predicted according to the data, so as to obtain a pollutant concentration prediction result corresponding to the target national control station. The target national control station may then be analyzed for pollution source contribution based on the pollutant concentration prediction.

It will be appreciated that, in the prior art, the method for predicting the concentration of the pollutant and analyzing the contribution of the pollutant may be adopted, and those skilled in the art may appropriately select the method according to the actual situation, which is not particularly limited in the embodiment of the present application.

In the process of carrying out pollution source contribution analysis, the electronic equipment can acquire the transmission contribution concentration and the local contribution concentration of the target national control station, and judge the magnitude relation of the transmission contribution concentration and the local contribution concentration. The transmission contribution concentration refers to the concentration of pollutants discharged by other grids when the pollutants are transmitted to the target national control station, and the local contribution concentration refers to the concentration of pollutants discharged by the grid where the target national control station is located.

It will be appreciated that, similar to the above embodiments, there are also a plurality of ways in which the electronic device obtains the transmission contribution concentration and the local contribution concentration, for example: receiving data sent by other devices; or, directly reading the stored data from the cloud database, etc., which is not limited in the embodiment of the present application.

If the electronic equipment judges that the transmission contribution concentration of the target national control station is smaller than the local contribution concentration, the influence of the locally discharged pollutants on the target national control station is larger, so that a global control scheme can be provided for the grid where the target national control station is located; correspondingly, if the electronic equipment judges that the transmission contribution concentration of the target national control station is larger than the local contribution concentration, the influence of pollutants discharged by other grids on the target national control station is larger, so that a neighborhood management and control scheme can be provided for the grid where the target national control station is located.

The global control refers to controlling pollutant discharge amounts of grids in a preset area range, and the neighborhood control refers to controlling pollutant discharge amounts of grids in a partial area corresponding to a target national control station. It should be noted that, in the following embodiments, specific implementations of global control and neighborhood control will be described in detail, and thus will not be described herein.

In the scheme, through contribution analysis on the pollution source, a global management and control scheme or a neighborhood management and control scheme can be selected to be provided for the target area, so that a more suitable prediction management and control scheme can be determined according to actual conditions.

Next, referring to fig. 2, fig. 2 is a flowchart of a real-time management and control method according to an embodiment of the present application, where the real-time management and control method may include the following:

step S201: and acquiring current observation data of the target national control station.

Step S202: judging whether preset conditions are met or not according to the current observation data and the prediction data.

Step S203: and when the preset condition is met, providing a neighborhood management and control scheme.

Specifically, the electronic device may acquire the current observation data and the prediction data of the target national control station, where the manner of acquiring the current observation data and the prediction data has been described in the foregoing embodiments, which are not described herein again. Then, the electronic device can judge whether the preset condition is met according to the current observation data and the prediction data, and provide a neighborhood management and control scheme when the preset condition is met.

Wherein, the preset condition may include one of the following: firstly, the current observed data is larger than a first preset threshold value; secondly, the current observed data is smaller than a first preset threshold value and larger than a second preset threshold value; thirdly, the difference value between the current observed data and the predicted data is larger than a third preset threshold value; fourth, the difference between the current observed data and the predicted data is smaller than a third preset threshold, and the pollutant data at the next moment determined according to the current observed data and the predicted data is larger than the first preset threshold. That is, when the current observed data and the predicted data satisfy any one of the four conditions described above, a neighborhood management and control scheme may be provided, otherwise, regardless of control or the next judgment step is performed.

For example, the electronic device may determine whether the current observed data is greater than a first preset threshold, and if the current observed data is greater than the first preset threshold, provide a neighborhood management and control scheme; if the current observed data is smaller than the first preset threshold, the electronic device can further judge whether the current observed data is larger than the second preset threshold. If the current observed data is smaller than a second preset threshold value, no pollutant control is needed; if the current observed data is greater than the second preset threshold, the electronic device may provide a neighborhood management and control scheme, and may further determine whether a difference between the current observed data and the predicted data is greater than a third preset threshold. If the difference value between the current observed data and the predicted data is larger than a third preset threshold value, the electronic equipment can provide a neighborhood management and control scheme, wherein the abnormal situation (such as the situation of illegal emission) possibly exists; if the difference between the current observed data and the predicted data is smaller than the third preset threshold, the electronic device may further determine whether the contaminant data at the next time determined according to the current observed data and the predicted data is greater than the first preset threshold. If the probability that the pollutant data at the next moment determined according to the current observation data and the prediction data is larger than the first preset threshold value is larger, the electronic equipment can provide a neighborhood management and control scheme; if the probability that the pollutant data at the next moment determined according to the current observation data and the prediction data is larger than the first preset threshold value is smaller, the emission of pollutants is not required to be controlled.

It can be understood that the above solution is only an example provided by the embodiments of the present application, and those skilled in the art may flexibly adjust the real-time control process in combination with practical situations, and the embodiments of the present application are not limited in particular. In addition, the magnitude relation among the first preset threshold, the second preset threshold and the third preset threshold is not particularly limited in the embodiment of the present application.

In the scheme, whether the target area needs to be managed and controlled in real time can be determined according to the current observation data of the target national control station, and a neighborhood management and control scheme is provided when the target area needs to be managed and controlled, so that the influence of pollutants is timely reduced.

The global management scheme and the neighborhood management scheme in the above embodiments are sequentially described in detail below.

Referring to fig. 3, fig. 3 is a flowchart of a method for global control of contaminants according to an embodiment of the present application, where the method for global control of contaminants may include the following:

step S301: and acquiring pollutant observation data of the target national control station and grid data corresponding to grids in a preset area range corresponding to the target national control station.

Step S302: and determining the predicted pollution time of the target national control station according to the pollutant observation data.

Step S303: and determining pollutant discharge amounts of the re-arranged grids in all grids in the preset area range and grid coordinates in the predicted pollution time according to the grid data.

Step S304: and determining a first pollution contribution ratio of each re-emission grid to the target national control station according to the pollutant emission amount of each re-emission grid, the grid coordinates, the target national control station coordinates and the meteorological element data, so as to control the target national control station according to the first pollution contribution ratio.

Specifically, the pollutant observation data of the target national control station may include: the historical and real-time pollutant observation data of the target national control station can comprise pollutant concentration, wind speed at each past moment, whether the target national control station exceeds standard, a control range, an influence range and the like. The mesh data may include: pollutant discharge amount of the grid and coordinates of the grid. The pollutant observation data are observation data obtained by observing the national control station, and the grid data are statistical data obtained by statistics.

It should be noted that, the manner in which the electronic device obtains the pollutant observation data of the target national control station and the grid data of all grids within the preset area where the target national control station is located is similar to the manner in which the data related to the pollutant is obtained in the above embodiment, and will not be repeated here.

According to the pollutant observation data of the target national control station, the predicted result of the pollutant concentration of the target national control station can be determined, and according to the predicted result, the predicted pollution time of the target national control station is [ t1, t2] and the duration is Deltat. That is, the target national control station observes the phenomenon that the concentration of the pollutant exceeds the standard between the time t1 and the time t 2.

The electronic device may then determine, based on the grid data, the pollutant discharge amounts of the re-placed grids in all grids within the preset area within the predicted pollution time, and the grid coordinates. The step S303 may specifically include the following:

and traversing the grid data of all grids at each moment in a preset time period before each pollution moment aiming at each pollution moment in the predicted pollution time.

And determining a re-emission grid corresponding to each moment in a preset time period according to the grid data, and pollutant emission quantity and grid coordinates of each re-emission grid.

That is, for each contamination timing T between [ T1, T2], the discharge amounts of all the grids at each observation timing within a time range (i.e., [ T1-T, T1 ]) of a length of a preset time period T before the contamination timing T is traversed, and the re-discharge grid corresponding to each timing is determined.

The preset time period T may be a constant, and the size of the preset time period T may be determined according to the size of the preset area range and the weather element data. As an embodiment, the meteorological element data may include a wind speed, and the preset time period T may be obtained according to the size of the preset area range and the wind speed, so that pollutants discharged by all grids at the boundary of the preset area range may reach the target national control station within the preset time period T.

It will be appreciated that in calculating the pollutant transport, attenuation factors may be added due to the existence of phenomena of dry sedimentation (caused by gravity, brownian motion, etc.) and wet sedimentation (caused by rainfall, etc.), thus making the calculated preset time period T more accurate.

After the traversal is completed, a four-dimensional array (Δt, N, T, 2) is obtained. Wherein the value range of Deltat is t1 to t2, which represents each time between t1 and t 2; the value range of N is the number of rearrangement lattices at the current moment, for example: the number of the rearrangement grids at the time t1 is 100, and the value range of the N at the time t1 is 1 to 100, which means that the 1 st rearrangement grid to the 100 th rearrangement grid; t is a constant and represents a preset time period in the above embodiment; and 2 is the coordinate of the current heavy-emission grid, and comprises two data of an x-axis coordinate and a y-axis coordinate.

It will be appreciated that since the pollutant emissions for each grid may be different at different times, it may be possible for one grid to belong to the re-emission grid at some times, not at some times, and the number of re-emission grids corresponding to each time is not necessarily the same.

For example, assuming T1 is 6 months, 5 days, 10 points, T2 is 6 months, 5 days, 12 points, each pollution time T is 1 hour apart, and T is 72 hours, the pollutant discharge amounts of all grids are traversed at intervals of one hour in a period from 6 months, 2 days, 10 points to 6 months, 5 days, 10 points; if the pollutant discharge amount of a certain grid at the current moment exceeds a preset threshold value, the grid at the moment is regarded as a rearrangement grid; then traversing the pollutant discharge amounts of all grids every one hour in the period from 11 points on 6 months and 2 days to 11 points on 6 months and 5 days; and finally traversing pollutant discharge amounts of all grids every one hour within a period from 12 points on 2 days of 6 months to 12 points on 5 days of 6 months.

The resulting four-dimensional array can be expressed as: (6 month 5 day 10 point, 1, 72 hours, (x 1, y 1)), (6 month 5 day 10 point, 2, 72 hours, (x 2, y 2)), … …, (6 month 5 day 12 point, 1, 72 hours, (x 3, y 3)), (6 month 5 day 12 point, 2, 72 hours, (x 4, y 4)), … ….

After obtaining the four-dimensional array in the above embodiment, that is, after determining the pollutant discharge amounts of the re-discharge cells and the cell coordinates in all the cells within the preset area within the predicted pollution time, the electronic device may determine the first pollution contribution ratio of each re-discharge cell to the target national control station based on the above data.

As an embodiment, the step S304 may specifically include the following:

and determining the position reached by the pollutant transmission of the re-emission grid in a preset time period according to the grid coordinates of each re-emission grid and the meteorological element data.

And determining the pollutant emission amount in a preset range of the target national control station transmitted at each pollution time according to the position reached by the pollutant transmission and the target national control station coordinates.

And determining the concentration of the pollutant in a preset range which is transmitted to the target national control station in the predicted pollution time according to the pollutant emission amount.

A first pollution contribution ratio is determined based on the concentration of the pollutant and the pollutant discharge amount.

First, the electronic device may calculate to which location the contaminants discharged by all the re-discharge grids determined in the above embodiments may be transferred within the preset time period T.

For example, also assume that T1 is 6 months 5 days 10 points, T2 is 6 months 5 days 12 points, each contamination moment T is 1 hour apart, and T is 72 hours. Taking a heavy discharge grid as an example for a period from 10 points on 6 months 2 days to 10 points on 6 months 5 days, the pollutant discharged from 10 points on 6 months 2 days can be considered to be transmitted 72 times when the pollutant is discharged from 10 points on 6 months 5 days, and the current position of the pollutant discharged from 10 points on 6 months 2 days can be obtained; the pollutant discharged from the point 11 on the 2 th month is transmitted 71 times at the point 10 on the 5 th month of 6 months, and the current position of the pollutant discharged from the point 10 on the 2 nd month of 6 months can be obtained at the moment; similarly, 72 positions of 72 pollutants discharged by the rearrangement network between the 10 th day of 6 months and the 10 th day of 5 days of 6 months can be obtained.

The other re-emission grids at other moments can be calculated in the above manner, and the final position of the pollutant transmission of each re-emission grid at each moment in the preset time period T can be finally obtained. According to the final position of the pollutant transmission calculated by the embodiment, whether the final position of the pollutant transmission is within the preset range (for example, three kilometers, ten kilometers and the like) of the target national control station can be judged.

Then, calculating how much pollutant (i.e., pollutant emission amount) is transmitted to a preset range of a target national control station in a preset time period T in the past by a certain re-emission grid at a certain moment; then, calculating how much pollutant (namely pollutant concentration) of a certain heavy emission grid is transmitted to a preset range of a target national control station between [ t1, t2 ]; finally, multiplying the pollutant concentration by the initial pollutant discharge amount of the rearrangement unit to obtain a value, and combining the values of all the rearrangement units to convert the value into a sum of 1 percent to obtain a first pollution contribution ratio of each rearrangement unit to the target national control station.

Based on the first pollution contribution ratio, the pollutant discharge amount required to be controlled in the whole preset area range is combined, and the pollutant discharge amount required to be controlled in each grid can be determined, so that the purpose of global control is achieved.

Therefore, according to pollutant observation data obtained by the observation of the target national control station and grid data obtained by statistics, specific time and area of pollutant emission and emission quantity of each grid which is specifically required to be controlled can be directly predicted, so that overall control of pollutants is realized, the cost for determining a control scheme is reduced, and the accuracy of the control scheme is improved.

Next, referring to fig. 4, fig. 4 is a flowchart of a method for managing a contaminant neighborhood according to an embodiment of the present application, where the method for managing a contaminant neighborhood may include the following steps:

step S401: and acquiring pollutant observation data of the target national control station and grid data corresponding to grids in a preset area range corresponding to the target national control station.

Step S402: and determining the predicted pollution time of the target national control station according to the pollutant observation data.

Step S403: and determining pollutant discharge amounts of the re-arranged grids in all grids in the preset area range and grid coordinates in the predicted pollution time according to the grid data.

Step S404: and determining a first pollution contribution ratio of each re-emission grid to the target national control station according to the pollutant emission amount, the grid coordinates, the target national control station coordinates and the meteorological element data of each re-emission grid.

Step S405: and determining a plurality of neighborhoods corresponding to the target national control station.

Step S406: and determining a second pollution contribution ratio of each neighborhood to the target national control station according to the first pollution contribution ratio so as to control the target national control station according to the second pollution contribution ratio.

Specifically, the steps S401 to S404 are similar to the specific implementation manners of the steps S301 to S304 in the foregoing embodiments, and are not repeated herein.

After the above step S404, a plurality of neighborhoods of the target national control station may be determined, wherein the neighborhood of the target national control station refers to an area within a certain range around the target national control station. As an implementation manner, the area within 30 km of the target national control station can be divided into 24 areas by taking the target national control station as the center of a circle, and the division manner is as follows: firstly, dividing the area into three concentric circles with the radius of 10 km, the radius of 20 km and the radius of 30 km, and dividing each concentric circle into eight parts on average, 24 polygonal areas can be obtained. It will be appreciated that these 24 polygonal areas may be considered as 24 neighbors of the target national control station.

Then, from the re-emission meshes within the 24 neighborhood regions, a second pollution contribution ratio for each neighborhood region may be determined from the area it occupies within each neighborhood region and the first pollution contribution ratio for each re-emission mesh.

For example, if a neighborhood is exactly a heavy discharge grid, then the second pollution contribution ratio of the neighborhood is equal to the first pollution contribution ratio of the heavy discharge grid; a neighborhood comprises half of one re-arrangement grid and half of the other re-arrangement grid, the second pollution contribution ratio of the neighborhood is equal to half of the first pollution contribution ratio of the first re-arrangement grid plus half of the first pollution contribution ratio of the second re-arrangement grid.
