Specific embodiment
The application is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining related invention, rather than the restriction to the invention.It also should be noted that for just
Part relevant to related invention is illustrated only in description, attached drawing.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
For the ease of being preferably illustrated to method involved in the application, " grid " is illustrated first below.
To achieve the purpose that Regional Atmospheric Pollution prevents and treats fine-grained management, according to different monitoring demand and environmental characteristic by mesh
Mark region is divided into different grids and carries out point arrangement, carries out real-time monitoring, referred to as net to concentration contaminants associated in each grid
It formats monitoring.The emphasis Polluted area that urban grid supervision is divided is known as " hot spot grid ".Highdensity gridding
Monitoring network Reasonable Arrangement types of functionality monitoring site, the air quality for being able to reflect emphasis Polluted area should become in region
Change, meets the needs of regional environment air monitoring, objectively evaluate the air quality of emphasis Polluted area.
Pollutant distribution situation can be assessed, in conjunction with resource and warp according to the diffusion of local pollutant, migration and transformation rule
The feasibility of Ji determines reasonable monitoring site, keeps data obtained representative.
In the reasonable monitoring site of the determination, gridding monitoring device can be set.Gridding monitoring device, which refers to, adopts
The detection method of scattering is used up, small in size, light-weight, the equipment for pollutant situation in automatic monitor for continuously surrounding air.
In a website, generally there is a standard monitoring device (alternatively referred to as state's control equipment or saving control equipment), at this
In a certain range of website, at least 3 gridding monitoring devices can be installed, this 3 gridding monitoring devices are known as Quality Control and set
Standby, this three Quality Control equipment constitute a Quality Control point.
Outside the Quality Control point, gridding monitoring device can also be equipped in multiple points.By a bigger region
After being divided into grid, which can also be divided into multiple sub-grids, which can also be divided into multiple small sub-grids, with
Improve the precision of pollutant monitoring.
It is understood that the concept of grid is opposite.For example, the city X can be divided into 36 grids, but by this 36
Each grid dividing in a grid is 36 small grids.Then grid involved in the application, can be 36 grids,
Be also possible to 36 small grids, as specifically any, it should be determined in practical applications, the application to this not
It limits.
The equal number of first and second hereinafter, it is only for distinguish, have no physical meaning.
Fig. 1 is the determination method flow schematic diagram for the pollutant concentration that the embodiment of the present invention one provides.The application of this method
Scene is gridding monitoring network, and the executing subject of this method can be the equipment with computing function, for example, computer, hand
The determining device of the machine perhaps computer such as determining device of pollutant concentration, mobile phone or pollutant concentration can be with grid
Change monitoring device to be connected, which can carry out by way of wirelessly or non-wirelessly communicating, and the application does not limit this.Such as
Shown in Fig. 1, method includes the following steps:
Step 101, the first point information and the first pollution object for obtaining at least three first equipment in the first grid are dense
Degree evidence.
Wherein, in order to get more accurate pollutant concentration data, region can be carried out to the division of gridding,
In first grid, including at least three the first equipment, the gridding monitoring device which can be Quality Control point (can also be with
Referred to as Quality Control equipment), example and it is non-limiting, the first equipment be 4.
Gridding monitoring device is launched to after Quality Control point, gridding monitoring device can obtain the pollution of the point in real time
Object concentration data, the pollutant concentration data may include the type and the concentration values of pollutant under the type of pollutant.This
When, " real-time " can be set in gridding monitoring device, can according to need, set, example and it is non-limiting, can
To be set as getting within one minute 60 pollutant concentration data, the data got in one minute are more, and subsequent first point
The pollutant concentration data of position are more accurate.
Example and it is non-limiting, pollutant can be fine particle (PM2.5), pellet (PM10), nitrogen dioxide
(Nitrogen dioxide, NO2), sulfur dioxide (Sulfur dioxide, SO2), carbon monoxide (Carbon monoxide,
CO), ozone (Ozone, O3) and total volatile organic compounds (Total Volatile Organic Compounds, TVOC)
In any one.
It is understood that pollutant can be any combination of above-mentioned pollutant in subsequent research, can pass through
Normalization method handles the unit of different pollutants, normalized pollutant concentration data is obtained as a result, to normalized
After pollutant concentration data carry out comprehensive descision, the pollutant concentration data of grid are calculated.
It is understood that pollutant concentration data herein and pollutant concentration data hereafter, refer to effectively
Data, for invalid data, meeting default setting is -999.
Step 102, the second point information and the second pollutant concentration data of the second equipment are obtained.
Step 103, the third point information and third pollutant concentration data of third equipment are obtained.
Wherein, the second equipment is to save control equipment, and third equipment is that equipment is controlled in state.Second equipment and third equipment can be located at
In first grid, it can also be located at outside the first grid, position of the application for the second equipment and third equipment and the first grid
Relationship is not defined.
Step 104, the whole subnet lattice information of the first grid, each sub-grid information in whole subnet lattice information are obtained
Location information including the sub-grid.
Specifically, the first grid may include certain amount sub-grid, example and it is non-limiting, the first grid includes 36
Sub-grid.
Step 105, the first data of first area are obtained, wherein the first data include first area location information and
The pollutant concentration data of first area.
Wherein, the first data can be wrfnc data, be the data obtained using preset model, training, the data
Storage is in the database.First area is region bigger than each small grid, but smaller than the first grid.
Wrfnc data include the location information of first area and the pollutant concentration data of first area.The location information
It can be longitude and latitude data, the pollutant concentration data of first area can be multiple.
Step 106, according to the location information of first area, the pollutant concentration data of first area and each sub-grid
Location information calculates the original pollutant concentration data of each sub-grid.
Wherein, step 106 specifically includes: firstly, being believed according to the position of the location information of first area and each sub-grid
