Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, an application method for tracing a pollution source influencing the deterioration of the environmental air quality in a certain area comprises the following steps: (1) manual inspection is used, however, the method is low in efficiency, and the inspection result is easily unreliable due to time lag and professional lack of personnel; (2) the method has the advantages that the spatial distribution of the pollutant concentration in a certain area is obtained by utilizing various monitoring devices, the pollution source investigation range is reduced, and the method for manpower analysis and inspection is assisted, however, the rapid tracing of the pollutant can not be realized by the method. In order to realize accurate and rapid tracing of the atmospheric pollution source, the azimuth and the distance of different potential pollution sources in a monitoring site area need to be associated with the monitoring site position in the atmospheric pollution rapid tracing implementation process, and as the potential pollution sources influencing pollution in a certain area are various, the association relationship between the pollution sources and the monitoring site is difficult to determine, so that the efficiency of tracing the pollution sources is influenced. Based on the method, the device and the terminal equipment for determining the pollution source associated information, the associated information between the pollution source and the monitoring site can be reliably determined, and therefore the efficiency of tracing the pollution source is remarkably improved.
To facilitate understanding of the present embodiment, first, a method for determining relevant information of a pollution source disclosed in the present embodiment is described in detail, referring to a flowchart of the method for determining relevant information of a pollution source shown in fig. 1, where the method mainly includes the following steps S102 to S108:
and step S102, determining a target monitoring site and a target pollution source to be associated. The target pollution source may be a linear pollution source, and the linear pollution source may be a linearly distributed pollution source such as road dust. In practical application, it is assumed that a plurality of monitoring stations (including a master station and/or a micro station) are arranged in a certain area, and when any monitoring station detects that a pollutant which meets preset linear pollution source characteristics reaches the monitoring station, the pollutant can be determined as a target pollution source, wherein the linear pollution source characteristics can be set based on actual requirements, such as when PM2.5 of the pollutant exceeds a preset threshold, the pollutant is determined as the target pollution source, and optionally, the target monitoring station can be selected from the plurality of monitoring stations based on location information of the target pollution source.
And step S104, calculating the monitoring angle of the target monitoring station relative to the target pollution source based on the station coordinates of the target monitoring station and the position information of the target pollution source. In one embodiment, a first azimuth angle of the starting point relative to the target monitoring station and a second azimuth angle of the ending point relative to the target monitoring station may be respectively determined based on the station coordinates, the starting point coordinates and the ending point coordinates, and an absolute value of an angle difference between the first azimuth angle and the second azimuth angle is the monitoring angle.
And step S106, dividing a plurality of angle sections according to preset wind direction groups. Wherein, wind direction group can include four wind directions, eight wind directions, sixteen wind directions etc to including sixteen wind directions as an example (refer to wind direction sixteen azimuth graph), the angle of every wind direction is 22.5 degrees, can obtain a plurality of angle intervals through making up the wind direction with different quantity, for example, the angle interval that the division obtained includes: 180 °, 157.5 ° to 180 °, 0 ° to 157.5 °.
And S108, determining the associated information between the target monitoring station and the target pollution source based on the angle interval of the monitoring angle. Wherein the associated information comprises an associated distance and/or an associated position. In practical application, if the monitoring angle is less than or equal to 180 °, the angle interval in which the monitoring angle is located may be directly determined, and if the monitoring angle is greater than 180 °, the difference between the monitoring angle and 360 ° needs to be calculated, so that the angle interval in which the monitoring angle is located is determined as the angle interval in which the monitoring angle is located based on the absolute value of the difference. In one embodiment, a calculation rule may be configured for each angle interval, so that the association information between the target monitoring station and the target pollution source is determined based on the calculation rule corresponding to the angle interval where the monitoring angle is located.
According to the method for determining the incidence relation of the pollution sources, provided by the embodiment of the invention, the angle section where the monitoring angle is located can be calculated based on the site coordinates of the target monitoring site and the position information of the target pollution sources, and the incidence information between the target monitoring site and the target pollution sources can be determined efficiently and reliably, so that the efficiency of tracing the pollution sources is obviously improved.
In practical applications, for example, the oil smoke pollution sources are point pollution sources distributed in a point shape, and the road dust pollution sources are line pollution sources distributed in a line shape, wherein the position and distance of the point pollution sources relative to the monitored site are fixed, and the associated information of the line pollution sources relative to the monitored site cannot be determined. Based on the above, the embodiment of the present invention provides the method for determining the pollution source associated information, so as to efficiently and reliably determine the associated information between the linear pollution source and the target monitoring station.
In an embodiment, the method for determining the pollution source associated information may be applied to a terminal device, and a graphical user interface is provided by the terminal device, and when the terminal device performs the step of determining the target monitoring station and the target pollution source to be associated, the following steps 1 to 4 may be referred to:
And 2, determining the associated area based on the starting point coordinate and the end point coordinate. Wherein, the monitoring sites contained in the association area need to be associated with the target pollution source. In one embodiment, the area within the preset radius range may be determined as the associated area based on a center point of a connection line between a start point corresponding to the start point coordinate and an end point corresponding to the end point coordinate. And assuming that the preset radius is 5km, taking the midpoint coordinate of a connecting line between the starting point and the ending point as the center of a circle, and taking 5km as the radius to determine an associated area, wherein the associated area should include at least one candidate monitoring station. In practical applications, the preset radius may be set based on actual requirements, which is not limited in the embodiment of the present invention.
And 3, displaying the candidate monitoring sites in the associated area through a graphical user interface. In practical application, the map of the associated area can be displayed through a graphical user interface, and all candidate monitoring sites located in the associated area are marked.
And 4, responding to the selection operation aiming at the candidate monitoring sites, and determining the target monitoring site. In practical application, when a user clicks a candidate monitoring site on a graphical user interface, the candidate monitoring site can be determined as a target monitoring site. For example, after determining the association information between one candidate monitoring site and the target pollution source, the candidate monitoring sites located in the association area may be continuously displayed through the graphical user interface, so that the user may continuously select the target monitoring site for association. Optionally, when the candidate monitored sites are subsequently displayed through the graphical user interface, the candidate monitored sites for which the corresponding association relationship is determined may be marked with a special mark so as to avoid repeated operations on the candidate monitored sites.
To facilitate understanding of the foregoing step S104, an embodiment of the present invention provides an implementation manner for calculating a monitoring angle of a target monitoring station relative to a target pollution source based on station coordinates of the target monitoring station and location information of the target pollution source:
(1) respectively determining a first azimuth angle of the starting point of the target pollution source relative to the target monitoring station and a second azimuth angle of the ending point of the target pollution source relative to the target monitoring station based on the station coordinates of the target monitoring station, the starting point coordinates of the target pollution source and the ending point coordinates of the target pollution source. For example, the target monitoring station is marked as a, the starting point is marked as B, and the end point is marked as C, the station coordinates of the target detection station a, the starting point coordinates of the starting point B, and the end point coordinates of the end point C are known, and the three points of the target detection station a, the starting point B, and the end point C may be connected to obtain a triangle, such as a schematic connection diagram shown in fig. 2, where fig. 2 illustrates a side a corresponding to the target detection station a, a side B corresponding to the starting point B, and a side C corresponding to the end point C, and in addition, fig. 2 also illustrates a first azimuth angle α 1 of the starting point B relative to the target detection station a, and a second azimuth angle α 2 of the end point C relative to the target detection station a.
In addition, please continue to refer to fig. 2, a first distance between the target monitoring station and the start point, a second distance between the target monitoring station and the end point, and a third distance between the start point and the end point may be respectively determined based on the station coordinates of the target monitoring station, the start point coordinates of the target pollution source, and the end point coordinates of the target pollution source. Wherein the first distance is the length of side c, the second distance is the length of side b, and the third distance is the length of side a.
(2) And determining the absolute value of the angle difference value between the first azimuth angle and the second azimuth angle as the monitoring angle of the target monitoring station relative to the target pollution source. Referring to fig. 2, the first azimuth angle α 1 is subtracted from the second azimuth angle α 2 to obtain an angle difference, and since the angle intervals are all between 0 ° and 180 °, if the angle difference is a negative value, a positive operation is required to be performed to obtain an absolute value of the angle difference, which is the monitoring angle, and if the angle difference is greater than 180 °, a calculation result obtained by subtracting the angle difference from 360 ° is required to be the monitoring angle.
In one embodiment, the angular interval includes a first interval, a second interval, and a third interval, for example, the first interval may be 180 °, the second interval may be 157.5 ° to 180 °, and the third interval may be Wie0 ° to 157.5 °. Based on this, the embodiment of the present invention provides an implementation manner for determining association information between a target monitoring station and a target pollution source based on an angle interval in which a monitoring angle is located, including the following three conditions:
and (I) if the monitoring angle belongs to the first interval, determining that the association distance is 0 and the association orientation is the relative orientation of the starting point and the ending point. For example, when the monitoring angle is 180 °, it is determined that the monitoring angle belongs to the first interval, that is, the target monitoring station is located on the connecting line between the starting point and the ending point, and at this time, it may be determined that the association distance is 0. For the associated orientation, the above-mentioned relative orientation is used to characterize the moving orientation of the target pollution source that can pass through the target monitoring station, for easy understanding, see fig. 3 for a schematic diagram of the target pollution source and the target monitoring station, fig. 3 illustrates that when the moving angle of the target pollution source is 0 to β 1 or β 2 to 360, the target pollution source can pass through the target monitoring station, and when the moving angle of the target pollution source is β 1 to β 2, the target pollution source cannot pass through the target monitoring station. Since the target pollution source needs to be traced by using the target monitoring station, the relative position can be determined as the associated position, that is, the associated position should be 0 to β 1 or β 2 to 360.
And (II) if the monitoring angle belongs to a second interval, calculating an associated distance based on the first distance, the second distance and the third distance, wherein the associated direction is the relative direction of the starting point and the ending point. For example, when 157.5 ° < monitoring angle <180 °, it is determined that the monitoring angle belongs to the second interval. For the correlation distance, the correlation distance can be calculated according to the following formula:
wherein M isaIndicating the association distance, a indicating the third distance, b indicating the second distance, c indicating the first distance. For the associated angle, refer to the above case (a), which is not described again in the embodiment of the present invention.
And (III) if the monitoring angle belongs to a third interval, calculating the association distance based on the first distance, the second distance and the third distance, and determining the association direction based on the number of the wind direction groups between the starting point and the ending point. For example, when 0 ° < monitoring angle <157.5 °, it is determined that the monitoring angle belongs to the third interval. For the associated distance, reference may be made to the aforementioned case (ii), which is not described again in the embodiments of the present invention. For the association angle, the wind direction groups can be obtained from the starting point B to the end point C and from the end point C to the starting point B clockwise, and the corresponding directions with small number of wind direction groups are obtained. The embodiment of the invention provides an implementation mode for determining the associated azimuth based on the number of wind direction groups between the starting point and the ending point, which is shown in the following steps a to d:
step a, determining a first central angle and a second central angle based on connecting lines of the starting point and the ending point with a target monitoring station respectively. With reference to fig. 2, a first central angle from the start point B to the end point C is determined to be γ 1, and a second central angle from the end point C to the start point B is determined to be γ 2.
And b, comparing the first number of the wind direction groups contained in the fan-shaped area corresponding to the first central angle with the second number of the wind direction groups contained in the fan-shaped area corresponding to the second central angle. Assuming a sixteen azimuth wind direction map, the angle of each wind direction is 22.5 °. For example, the first central angle γ 1 is 90 °, which contains the first number of wind direction groups to be 4; the second central angle γ 2 will be 270 °, which contains a second number of wind direction groups of 12. Or, for example, the first central angle γ 1 is 270 °, which contains the first number of wind direction groups to be 12; the second central angle γ 2 will be 90 °, which contains a second number of wind direction groups of 4.
And c, if the first number is smaller than the second number, determining the first central angle as the associated azimuth. Assuming that the first number is 4 and the second number is 12, the associated orientation may be determined to be a first central angle γ 1.
And d, if the second number is smaller than the first number, determining the second central angle as the associated azimuth. Assuming a first number of 12 and a second number of 4, the associated orientation may be determined to be a second central angle γ 2.
In summary, the embodiments of the present invention can determine the associated distance and the associated position between the linear pollution source and the monitored site. When the pollutants according with the preset linear pollution source characteristics reach the monitoring station, the starting point coordinates and the end point coordinates of the linear pollution source are detected through the monitoring station, and the associated distance and the associated direction are determined according to the method provided by the embodiment, so that the pollution source can be quickly locked, or the linear pollution source is listed as a highly suspected pollution source list, quick and effective tracing data are provided, and a basis is provided for a related department to quickly process pollution events.
