Description

Technical Field

[0001] The present invention relates to the technical field of air pollution control, and in particular to a method and system for achieving directional transmission targets of air monitoring sites based on a map. Background Art

[0002] Since atmospheric transmission has no spatial restrictions, in the scenario of air pollution control and prevention, multiple air monitoring stations are generally set up in a control area. Atmospheric monitoring stations in different directions can better reflect the air pollution values ​​in the control area.

[0003] At present, the atmospheric pollution control platform is usually used to visualize the atmospheric pollution values ​​in the control area, so that the control personnel can view the atmospheric pollution values ​​in the control area. However, when an atmospheric pollution value exceeds the standard warning at a certain atmospheric monitoring station or multiple atmospheric monitoring stations on the atmospheric control platform, it is difficult for the control personnel to determine the atmospheric pollution transmission path, and thus it is impossible to locate the next transmission target along the way, resulting in the control personnel being unable to implement effective atmospheric control measures. Summary of the invention

[0004] The purpose of the present invention is to provide a method and system for realizing directional transmission targets of atmospheric monitoring sites based on maps. The method mainly orients the atmospheric pollution transmission path where the atmospheric monitoring site is located based on the atmospheric management platform, and locates the next transmission target along the way in different directions of the atmospheric monitoring site, so as to facilitate the control personnel to view it on the atmospheric management platform, thereby implementing effective atmospheric control measures.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions:

[0006] A method for achieving directional transmission targets of an atmospheric monitoring site based on a map, the method specifically comprising the following steps:

[0007] S1: Get the layer mask a corresponding to the current atmospheric monitoring site on the map;

[0008] Each layer mask a takes the coordinate position of the atmospheric monitoring station as the center point, and the layer mask a is divided into four transmission areas by the horizontal and vertical lines where the center point is located;

[0009] S2: Obtain the current air pollution index corresponding to the current air monitoring site, and compare the current air pollution index with the pollution threshold. If the current air pollution index is greater than the pollution threshold, go to step S3; if the current air pollution index is less than or equal to the pollution threshold, go to step S4;

[0010] S3: obtaining the current meteorological data of the current atmospheric monitoring site on the layer mask a, and searching for the target site on the layer mask a according to the current meteorological data, and obtaining the transmission targets respectively located in the four transmission areas;

[0011] S4: Search for similar sites on layer mask a according to the coordinate position of the current atmospheric monitoring site, and obtain transmission targets located in four transmission areas respectively.

[0012] Furthermore, in S3, the process of searching for a target site on layer mask a according to the current meteorological data specifically includes the following steps:

[0013] SA1: Calculate the wind direction according to the current meteorological data, obtain the wind direction line corresponding to the current atmospheric monitoring station on the layer mask a, and obtain the corresponding upwind direction and downwind direction on the layer mask a according to the wind direction line;

[0014] SA2: Search for target sites in the upwind direction and the downwind direction respectively, and obtain the corresponding transmission targets in the upwind direction and the corresponding transmission targets in the downwind direction, that is, obtain the transmission targets in the transmission area where the upwind direction is located and the transmission targets in the transmission area where the downwind direction is located respectively;

[0015] SA3: Exclude the transmission area in the upwind direction and the transmission area in the downwind direction to obtain the remaining two transmission areas. Search for similar sites in the remaining two transmission areas according to the coordinates of the current atmospheric monitoring site to obtain the transmission targets located in the remaining two transmission areas.

[0016] Furthermore, in SA2, the specific process of searching for the target site in the upwind direction and the downwind direction is as follows:

[0017] Taking the center point of layer mask a as the center of the circle, from the center of the circle outward, the atmospheric monitoring stations in the upwind direction and the downwind direction are judged in turn to determine whether the current atmospheric pollution index corresponding to the atmospheric monitoring station is greater than the pollution threshold. If so, the atmospheric monitoring station is used as the corresponding transmission target in the upwind direction or the downwind direction.

[0018] Further, in SA2, after judging the atmospheric monitoring stations in the upwind direction in sequence, if the current atmospheric pollution indexes corresponding to all atmospheric monitoring stations in the upwind direction are less than or equal to the pollution threshold, the atmospheric monitoring station closest to the current atmospheric monitoring station among all atmospheric monitoring stations is used as the corresponding transmission target in the upwind direction;

[0019] Similarly, after judging the atmospheric monitoring stations in the downwind direction in turn, if the current atmospheric pollution indexes corresponding to all atmospheric monitoring stations in the downwind direction are less than or equal to the pollution threshold, the atmospheric monitoring station closest to the current atmospheric monitoring station among all atmospheric monitoring stations will be used as the corresponding transmission target in the downwind direction.

[0020] Furthermore, the process of searching for similar sites on layer mask a according to the coordinate position of the current atmospheric monitoring site is as follows:

[0021] In layer mask a, take the center point as the center of the circle, search outward from the center of the circle to obtain the atmospheric monitoring station closest to the current atmospheric monitoring station, and use the transmission area where the atmospheric monitoring station is located as the transmission target in the corresponding transmission area.

[0022] Furthermore, on the layer mask a, with the center point as the center of the circle, starting from the north, the entire circle is equally divided into 16 wind direction positions, and the wind direction indicator line on the layer mask a indicates that the wind blows from one wind direction position to another wind direction position, then the wind direction position that the wind blows first is the upwind direction position, and the wind direction position that the wind blows later is the downwind direction position.

[0023] Furthermore, step S0 is included, which is before step S1. Step S0 is specifically:

[0024] S0: Obtain the site information of all atmospheric monitoring sites, substitute the longitude and latitude coordinates in the site information into the unified coordinate correction calculation, obtain the atmospheric monitoring sites located in the same coordinate system, and establish a map based on the atmospheric monitoring sites located in the same coordinate system.

[0025] Furthermore, in S2, the air pollution index is generated based on the monitoring data of the current air monitoring site, and the monitoring data include PM2.5 concentration, PM10 concentration, CO concentration, NO2 concentration, SO2 concentration, and O3 concentration. The IAQI calculation is performed on each of them to obtain the corresponding air pollution index, and the largest air pollution index is used as the current air pollution index corresponding to the current air monitoring site.

[0027] Layer mask acquisition module: obtain the layer mask a corresponding to the current atmospheric monitoring station on the map. Each layer mask a takes the coordinate position of the atmospheric monitoring station as the center point, and the layer mask a is divided into four transmission areas by the horizontal and vertical lines where the center point is located;

[0030] The second transmission target orientation module: according to the coordinate position of the current atmospheric monitoring site, a search for similar sites is performed on the layer mask a to obtain transmission targets located in four transmission areas.

[0031] Furthermore, the first transmission target orientation module includes the following modules:

[0032] Wind direction calculation module: calculate the wind direction according to the current meteorological data, obtain the wind direction line corresponding to the current atmospheric monitoring station on the layer mask a, and obtain the corresponding upwind direction and downwind direction on the layer mask a according to the wind direction line;

[0033] Wind direction target search module: Search for target sites in the upwind direction and downwind direction respectively, and obtain the corresponding transmission targets in the upwind direction and the corresponding transmission targets in the downwind direction, that is, obtain the transmission targets in the transmission area where the upwind direction is located and the transmission targets in the transmission area where the downwind direction is located respectively;

[0063] Taking the center point of layer mask a as the center of the circle, from the center of the circle outward, the atmospheric monitoring stations in the upwind direction and the downwind direction are judged in turn to determine whether the current atmospheric pollution index corresponding to the atmospheric monitoring station is greater than the pollution threshold.

[0067] In layer mask a, take the center point as the center of the circle, search outward from the center of the circle to obtain the atmospheric monitoring station closest to the current atmospheric monitoring station, and use the transmission area where the atmospheric monitoring station is located as the transmission target in the corresponding transmission area.

[0068] Preferably, on the layer mask a, the center point is taken as the center of the circle, starting from the north, and the entire circle is equally divided into 16 wind direction positions, and the wind direction indicator line on the layer mask a indicates that the wind blows from one wind direction position to another wind direction position, then the wind direction position that the wind blows first is the upwind direction position, and the wind direction position that the wind blows later is the downwind direction position.

[0069] Preferably, the method further includes step S0, which is before step S1. The specific steps of step S0 are:

[0070] S0: Obtain the site information of all atmospheric monitoring sites, substitute the longitude and latitude coordinates in the site information into the unified coordinate correction calculation, obtain the atmospheric monitoring sites located in the same coordinate system, and establish a map based on the atmospheric monitoring sites located in the same coordinate system.

[0071] Preferably, in S2, the air pollution index is generated based on the monitoring data of the current air monitoring site, and the monitoring data include PM2.5 concentration, PM10 concentration, CO concentration, NO2 concentration, SO2 concentration, and O3 concentration, and the IAQI calculation is performed on each of them to obtain the corresponding air pollution index, and the largest air pollution index is used as the current air pollution index corresponding to the current air monitoring site.

[0072] Based on the above principles, the present invention is further described:

[0073] The present invention is mainly applied to an intelligent atmospheric monitoring and governance platform (Alpha MAPS), which is based on static and dynamic urban data and combines mobile monitoring methods to build an urban ecological brain. Through the artificial intelligence learning framework, closed-loop learning is carried out with pollution control and governance cases as samples to conduct all-round supervision of the atmospheric environment in key areas; analyze atmospheric pollution phenomena, explore atmospheric pollution sources, identify responsible entities, and push and handle pollution problems in the first place, which helps improve and enhance the quality of urban atmospheric environment and provide decision-making support for atmospheric environmental management.

[0074] Based on the above-mentioned intelligent atmospheric monitoring and governance platform (Alpha MAPS), control personnel can monitor the atmospheric pollution values ​​in the control area through multiple atmospheric monitoring stations on the intelligent atmospheric monitoring and governance platform. However, the intelligent atmospheric monitoring and governance platform is currently only used to visualize the atmospheric pollution values ​​of the monitored atmospheric monitoring stations, thereby facilitating control personnel to view the atmospheric pollution values ​​in the control area.

[0075] However, when an atmospheric pollution value exceeding the standard warning appears at a certain atmospheric monitoring station or multiple atmospheric monitoring stations on the intelligent atmospheric monitoring and management platform, it is difficult for control personnel to directly observe the atmospheric pollution transmission path through the intelligent atmospheric monitoring and management platform, and thus cannot directly locate the next transmission target along the way, resulting in the inability of control personnel to quickly and effectively implement atmospheric control measures.

[0076] Therefore, the present invention provides a method for realizing directional transmission targets of atmospheric monitoring sites based on maps, which can be applied to intelligent atmospheric monitoring and governance platforms. The intelligent atmospheric monitoring and governance platform will monitor the atmospheric pollution values ​​of atmospheric monitoring sites through maps. Based on the above map, the atmospheric pollution transmission path where the atmospheric monitoring site is located is directional processed, and the next transmission target along the way is positioned in different directions of the atmospheric monitoring site. The atmospheric pollution transmission path where the atmospheric monitoring site is located and the next transmission target along the way can be directly displayed on the map, which is convenient for management and control personnel to view on the intelligent atmospheric monitoring and governance platform, thereby implementing effective atmospheric control measures.

[0077] In this embodiment, a plurality of atmospheric monitoring sites are mapped on the map for display on the intelligent atmospheric monitoring and governance platform, wherein the atmospheric monitoring sites can be mapped to the map through the longitude and latitude coordinates of the atmospheric monitoring sites. Specifically, it is first necessary to correct the longitude and latitude coordinates of all atmospheric monitoring sites, and determine the coordinate system of the longitude and latitude coordinates of all atmospheric monitoring sites. If they are BD02 or WSG84, they are transmitted to the unified coordinate correction calculation service. Through encryption and offset calculation, it is ensured that the coordinate system of all points is GCJ02, and then they can be mapped to the map. Figure 2 shown.

[0078] In addition, the map can be depicted in detail based on the site information characteristics of the atmospheric monitoring station, and the site information includes: the altitude of mountains in the area, the altitude of super-high buildings in the area, the distribution and area of ​​green spaces, contour data, etc.

[0079] Since there is a lot of data on the atmospheric monitoring stations on the map, in order to facilitate the management and control personnel to conduct detailed observations of the atmospheric monitoring stations and make the atmospheric pollution transmission path where the atmospheric monitoring stations are located based on the map generated and the next transmission target along the way clearer, the present invention chooses to generate a layer mask a corresponding to the atmospheric monitoring stations on the map, so that the management and control personnel can achieve a directional transmission target for an atmospheric monitoring station based on the layer mask a.

[0080] Specifically, Figure 3 As shown, in the map, a layer mask a is formed with the atmospheric monitoring site X, and the layer mask a takes the coordinate position of the atmospheric monitoring site as the center point, and the layer mask a is divided into four transmission areas, namely the first area, the second area, the third area, and the fourth area, by the horizontal line and vertical line where the center point is located.

[0081] Then, based on the above layer mask a, the monitoring data of the atmospheric monitoring station X can be obtained in real time, and the current atmospheric pollution index can be calculated according to the monitoring data of the station.

[0082] In this embodiment, the monitoring data includes PM2.5 concentration, PM10 concentration, CO concentration, NO2 concentration, SO2 concentration, and O3 concentration. The above 6 monitoring data are respectively transmitted to the IAQI calculation service, and the IAQI calculation is performed with reference to the national standard file to obtain respective IAQI values, which can be numbered as {IAQI1, IAQI2, ..., IAQI6}. Then, AQI calculation is performed based on the IAQI value, AQI=max{IAQI1, IAQI2, ..., IAQI6}, and AQI is used as the air pollution index. Based on the AQI and the preset pollution threshold, it can be determined whether the air pollution index of the current air monitoring site exceeds the standard. When it exceeds the standard, an early warning will be issued.

[0083] Specifically, the pollution threshold is preset to 50. When AQI>50, it means that the current air pollution index of the air monitoring station X exceeds the standard, and the target station is searched on the layer mask a according to the current meteorological data; when AQI<=50, it means that the current air pollution index of the air monitoring station X does not exceed the standard, and a similar station is searched on the layer mask a according to the coordinate position of the current air monitoring station.

[0084] Based on the above, since the current air pollution index of the air monitoring site X exceeds the standard, it means that the air monitoring site X has pollution transmission, and the air pollution will be transmitted following the atmospheric wind direction. Therefore, when searching for the target site for the air monitoring site X with pollution transmission, it is necessary to search according to the current wind direction of the air monitoring site X, wherein the wind direction is calculated according to the meteorological data, and the wind direction is divided into upwind and downwind directions, so a wind direction line with an arrow pointing can be formed on the layer mask a, and the wind direction line is a diagonal line, then the transmission area pointed by the arrow of the wind direction line is the transmission area where the downwind direction is located, and the transmission area pointed by the tail of the wind direction line is the transmission area where the upwind direction is located, such as Figure 4 As shown, forming a wind direction indicator line on layer mask a can help control personnel understand the current wind direction and the target sites that the current wind direction may transmit.

[0085] In addition, layer mask a is divided into 16 area blocks according to the 16 wind directions, that is, 360° is divided into 16 parts, due north = 0° (360°), due east = 90°, due south = 180°, due west = 270°, and each area block corresponds to a wind direction, such as Figure 5As shown, based on the layer mask a, the area block corresponding to the downwind direction and the area block corresponding to the upwind direction can be obtained, and then, the upwind direction and the downwind direction are respectively searched for other atmospheric monitoring stations with AQI>50 and the nearest along the way, and they are used as the transmission targets in the transmission area; the two transmission areas where the upwind direction and the downwind direction are not located are searched for other nearest atmospheric monitoring stations, and they are used as the transmission targets in the transmission area. Then, there is one transmission target in the first area, the second area, the third area, and the fourth area, respectively, as shown in FIG. Figure 6 As shown, the present invention judges targets along the way in four directions, so that it can more comprehensively analyze and orient the atmospheric pollution transmission path where the atmospheric monitoring station is located and the next transmission target along the way, which is convenient for control personnel to implement control.

[0086] In another embodiment, since the current air pollution index of the air monitoring site X does not exceed the standard, it means that the air monitoring site X does not currently have pollution transmission, and a search for a nearby site can be performed on the layer mask a according to the coordinate position of the current air monitoring site, and the site closest to the air monitoring site X is searched according to the longitude and latitude coordinates of the site in the first area, the second area, the third area, and the fourth area, such as Figure 7 As shown, they are respectively used as transmission targets in the first area, the second area, the third area, and the fourth area. Because the air pollution values ​​of the air monitoring stations with similar distances are most likely to pollute the air pollution index of the air monitoring station X at the next time point, they are used as transmission targets.

[0087] In summary, the present invention takes into account the diffusion characteristics of atmospheric transmission, and searches for transmission targets in different directions according to the wind direction and distance of atmospheric transmission, making the present invention more comprehensive in targeting directional transmission targets of atmospheric monitoring stations.

[0088] In addition, the present invention establishes a layer mask a related to the atmospheric monitoring site on the intelligent atmospheric monitoring and management platform. When the control personnel want to monitor the atmospheric monitoring site, they only need to click on the atmospheric monitoring site on the intelligent atmospheric monitoring and management platform, and the layer mask a corresponding to the atmospheric monitoring site will be displayed. In the present invention, the layer mask a is not only used to display the atmospheric pollution value of the atmospheric monitoring site, but also used to display the atmospheric pollution transmission path corresponding to the atmospheric monitoring site and the next transmission target along the way, so as to facilitate the control personnel to carry out effective atmospheric control.

[0089] In another embodiment, the atmospheric monitoring sites can also be numbered, with the number being the key, and the corresponding 4 point sets being the location written as the value, which are serialized and combined into a JSON format string J, and an isPollution field is added to the value to mark whether the pollution exceeds the standard. The value is true for the site exceeding the standard, otherwise it is false. When isPollution is true, a passage field is added to store the corresponding upwind (up) and downwind point marks (down). An example of the J string structure is as follows: {P1:{"location":{k1,k2,k3,k4},"isPollution":true,"passage":{up:k1,down:k3}}, P2:{"location":{k1,k2,k3,k4},"isPollution":false}.......}.

[0090] According to the number of the atmospheric monitoring station, the corresponding information can be displayed on the layer mask a, and information windows can be drawn on both sides of the layer mask a to prompt the detailed information of the point, so as to improve the information acquisition efficiency of the user on a single screen; pollution can also be marked in the corresponding transmission area according to the character string, specifically: if the isPollution mark in the J string corresponding to the point is true, the passage field content is read, and a red background highlight is added to the corresponding quadrant bx area corresponding to kx of up and down, and an information window is drawn for the up area to mark that there is a pollution point in the upwind direction, and an information window is drawn for the down area to mark that there is a pollution point in the downwind direction. When the control personnel triggers and clicks on the layer mask a, the station information corresponding to the atmospheric monitoring station and the transmission target of the atmospheric monitoring station in different transmission areas can be displayed according to the associated information. According to the transmission target, the atmospheric pollution transmission path corresponding to the atmospheric monitoring station and the next transmission target along the way can be indicated.
