[0002] With the deepening of air pollution prevention and control work, the precise supervision and dynamic analysis of pollution sources have become the core demand of the modernization of environmental governance system. At present, although an online monitoring network covering key enterprises has been established in the field of environmental monitoring in China, there are still many technical bottlenecks in the dynamic analysis and visualization decision support of pollution sources.

[0003] The existing visualization platform generally uses the display method of superimposing pollution concentration contour lines on static maps, and the display effect is single. In addition, in the pollution emergency response scene, the existing early warning information is usually published in a static "one-size-fits-all" mode, which cannot be dynamically adjusted according to the situation of the on-site personnel, and the human-computer interaction ability is weak, and the information display effect is deviated.

[0004] Therefore, it is urgent to build a visualization display system for air-related pollution sources that can realize multi-terminal intelligent linkage and improve the information display effect. SUMMARY

[0034] Further details are described below through a specific embodiment:

[0035] Embodiment One

[0036] As shown in the figure, one air pollution source visualization display system of the embodiment includes an information query module, a graph generation module, a scheduling module and a terminal interaction module. Figure 1 The information query module is configured to obtain pollutant diffusion data of the air-related industrial source enterprise from a preset interface; the pollutant diffusion data includes emission data, pollutant distance, pollutant area range information, etc.; the emission data includes pollutant concentration, pollutant emission amount, collection time and information of the air-related industrial source enterprise; the pollutant concentration and the pollutant emission amount are, for example, carbon monoxide concentration, carbon monoxide emission amount, sulfur dioxide concentration, sulfur dioxide emission amount, oxygen, nitrogen oxide concentration, nitrogen oxide emission amount, hydrogen chloride concentration, smoke concentration, smoke emission amount, flue gas pressure, flue gas temperature, non-methane total hydrocarbon concentration, etc.

[0037] The graph generation module is configured to visually render on a GIS map according to the pollutant diffusion data, generate a pollutant diffusion map and store the same; the pollutant diffusion map includes concentration levels of different areas; in the embodiment, the concentration levels include high, medium and low, and the concentration levels are divided by preset concentration range values.

[0038] In the embodiment, a Gaussian plume diffusion model is used to analyze the pollutant diffusion data for visual rendering. The pollutant concentration model equation of any point is as follows:

[0039]

[0040] In the equation, c is the pollutant concentration, mg / m 3 ;

[0041] Q is the source strength, mg / s;

[0042] u is the average wind speed at the exhaust pipe height, m / s; in the embodiment, the wind speed is collected by a wind speed meter installed at a corresponding position and obtained by the information query module;

[0043] y and z are diffusion parameters on the y-axis and the z-axis represented by the concentration standard deviation, respectively.

[0044] H is the effective height of the emission source, m.

[0045] ​

[0046] The Gaussian plume dispersion model is a mature technology and will not be described here.

[0047] The graphic generation module is further configured to generate a pollution source emission statistical chart according to the emission data; the pollution source emission statistical chart includes a line graph of concentration / emission of each pollutant changing over time and a ring chart of proportion of total emission of the same pollutant of different enterprises. For example, the line graph of concentration of each pollutant changing over 1 month.

[0048] The dispatching module is configured to determine a pollution range according to the pollution diffusion map, query display devices within the diffusion range from a preset display device database, and push the pollution diffusion map to the corresponding display devices. In this embodiment, the push range is limited, the dispatching module first filters out the pollution diffusion range with a concentration level higher than a preset level (for example, medium), and based on the determined pollution diffusion range and the position coordinates of each display device in the preset display device database, the display devices located within the determined pollution diffusion range are filtered out, the information push interface of the corresponding display devices is called, and the pollution diffusion map is pushed. The display device database created in advance obtains the information push interface of the display devices within the designated linkage display range, so as to facilitate subsequent information push. The linkage display range is, for example, municipal outdoor display devices within a certain administrative region, economic development zone, or outdoor and indoor display devices within a large factory area such as an industrial park. By integrating the display devices of the pollution diffusion range and linkage displaying the pollution diffusion map, people within the pollution diffusion range can easily understand the current overall pollution situation and how to avoid pollution.

[0049] The terminal interaction module is configured to upload the current positioning information to the dispatching module at startup; the dispatching module is configured to determine whether the user is within a preset distance of the display device according to the positioning information, and if so, push the line graph of concentration / emission of each pollutant changing over time to the terminal interaction module; in this embodiment, the preset distance is 5 meters. The terminal interaction module is an application installed on the user's smart phone. The terminal is usually equipped with relevant management personnel for easy multi-device information query.

[0050] The terminal interaction module is further configured to send a query request to the dispatching module, and the dispatching module is further configured to push the corresponding pollution source emission statistical chart according to the query request, realizing the user's autonomous query.

[0051] This solution precisely matches pollution trends with outdoor display terminals, projecting pollution information in key areas onto corresponding electronic screens in real time, improving the effectiveness of pollution information dissemination. It also establishes an interactive channel between mobile devices and fixed display devices. When users approach display devices near pollution sources, they have a greater demand for relevant information. The terminal automatically displays a line graph showing the daily changes in pollutant concentrations and emissions over time, allowing users to quickly understand the current pollution situation. This is faster and provides a better experience than manual querying.

[0052] Example 2

[0053] The difference between this embodiment and the first embodiment is that, in this embodiment, the information query module is further used to receive air pollution warning information; the air pollution warning information includes blue warning, yellow warning, orange warning or red warning.

[0054] The scheduling module is also used to determine whether the warning level is higher than the preset atmospheric pollution level (for example, orange warning) after receiving the atmospheric pollution warning information. If it is higher, the pollution progress information is created based on the pollution source emission statistical chart. In this embodiment, the pollution progress information is a collection of various pre-set line graphs and ring graphs that reflect the pollutant concentration / emission amount. The specific order and content of the line graphs and ring graphs are preset and laid out by the management personnel. The scheduling module calls the corresponding line graphs and ring graphs and places them at the specified position on the page to form the pollution progress information.

[0055] The information query module is also used to determine whether the user is within the pollutant diffusion range based on the current positioning information of the terminal interaction module after receiving the air pollution warning information; if the user is within the pollutant diffusion range, the user's movement trajectory is determined based on the historical positioning information, the frequency of pushing pollution progress information is determined based on the movement trajectory, and the pollution progress information is pushed to the terminal interaction module;

[0056] Users whose movement trajectory moves from a low-density area to a high-density area will receive push notifications more frequently than users whose movement trajectory moves from a high-density area to a low-density area. For example, users whose movement trajectory moves from a low-density area to a high-density area will receive push notifications once every hour, while users whose movement trajectory moves from a high-density area to a low-density area will receive push notifications once every six hours.

[0057] The solution of this embodiment is based on an adaptive push strategy based on the movement trajectory of personnel. Warning information can be pushed in a graded manner according to the behavioral characteristics of evacuating or approaching the core pollution area, thereby avoiding information overload and ensuring the reach rate of key warnings.

[0058] Example 3

[0059] The difference between the embodiment and the embodiment two is that in the embodiment, the graphic generation module is further configured to synthesize the generated pollutant diffusion maps in a preset time into a pollutant dynamic diffusion map; in the embodiment, an 8-hour pollutant dynamic diffusion map is synthesized, as shown in Figures 2-5

[0060] The scheduling module is further configured to obtain the user identity information from the terminal interaction module.

[0061] The scheduling module is further configured to query the size information of the display device within the diffusion range from the preset display device database, determine the playing speed of the pollutant dynamic diffusion map according to the size information, and push the pollutant dynamic diffusion map to the corresponding display device. In the embodiment, the playing speed is 0.5-1.5 times, wherein the larger the displayable area size of the display device is, the slower the playing speed is. For example, the displayable area sizes of three display devices A, B and C decrease successively, and the corresponding playing speeds are 0.5 times, 1 times and 1.5 times respectively. Generally, the size of the display device has a correlation with the distance of the user's view, and the larger the size of the display device is, the farther the distance of the user's view is generally; for example, a large screen outdoors, the user generally watches from a relatively far distance, and reducing the playing speed can ensure that the user has enough time to understand the relevant information.

[0062] The scheduling module is further configured to detect that the terminal interaction module is within a preset distance of the display device, determine whether the display module is in a state of displaying the pollutant dynamic diffusion map, and if not, adjust to the state of displaying the pollutant dynamic diffusion map. Generally, the display device is a non-dedicated weather information display screen, and it will also play other information cyclically, for example, a display screen in a park plays a park promotional video, enterprise advertisements, pollutant dynamic diffusion maps, weather forecasts and other information cyclically; the scheduling module detects that the terminal interaction module is within a preset distance of the display device, that is, the user opens the corresponding application, at this time, the display of the pollutant dynamic diffusion map is switched, which can ensure that the user views the pollutant dynamic diffusion map in time while minimizing the impact on the normal playing order.

[0063] ​The terminal interaction module is also configured to upload page browsing information to the scheduling module in real time when the display device is within the preset distance; the scheduling module is also configured to determine whether the user drags the page according to the page browsing information, and slow down the playing speed of the dynamic diffusion map of the pollutant of the corresponding display device when the user stops dragging the page. When the playing speed has reached the lowest, it remains unchanged, for example, 0.5 times without adjustment. In the embodiment, when there are multiple users within the preset distance of the display device, the terminal interaction module of the user with the highest position is used as the criterion. When the user stops dragging the page, it may be necessary to analyze the relevant situation in combination with the dynamic diffusion map of the pollutant, at which time the playing speed is reduced to facilitate the user to have sufficient time to understand the diffusion situation. Compared with the user repeatedly switching between various charts and the dynamic diffusion map of the pollutant on the smart phone, the multi-screen display of the dynamic diffusion map of the pollutant and various charts is realized, which facilitates the user to analyze and view on site.

[0064] The scheduling module is also configured to obtain map type switching request information from the terminal interaction module, determine whether there is switching authority according to the user identity information; if there is switching authority, determine whether the terminal interaction module is within the preset distance of the display device, if yes, the graphic generation module re-renders and generates a dynamic diffusion map of the pollutant according to the map type switching request information; the scheduling module is also configured to send the re-generated dynamic diffusion map of the pollutant to the corresponding display module. The user identity information includes the name, position and assigned authority of the user, for example, Zhao XX, an ordinary user, no relevant authority; Qian XX, a park management personnel, has switching authority; the map type includes a standard two-dimensional graphic map, a satellite map and a 3D map. The individualized configuration of the map type can be realized for different display areas.

[0065] The scheduling module is also configured to determine that the user is out of the preset distance of the display device according to the positioning information, and restore the display device to the initial display state after a certain setting time, for example, restore the initial playing speed, restore the initial diffusion frequency of the dynamic diffusion map of the pollutant, etc., to reduce the interference on the normal playing plan.

[0066] Embodiment Four

[0067] The difference between the present embodiment and Embodiment Three is that in the present embodiment, the scheduling module is also configured to count the number of users currently located within the preset distance of the display device through the current positioning information of the terminal interaction module, determine whether the number of users is greater than a preset number, if yes, analyze whether it is a preset action according to the user identity information. In the present embodiment, the preset number is 5, and it is determined to be a preset action, for example, a pollution disposal action, according to the analysis of the personnel of the relevant pollution prevention and control management department.

[0068] If the preset action is performed, the positioning information of the terminal interaction module to which the current user belongs is continuously acquired, the moving track is analyzed, and it is judged whether the current user stays at a preset distance of another display device for more than a set time according to the moving track. If the current user stays at the preset distance of another display device for more than the set time, the display time length of the dynamic diffusion map of the pollutant is increased, and the current user is given the screen projection right of the current display device. In the embodiment, the set time is 3 minutes.

[0069] The scheduling module receives the screen projection request of the terminal interaction module to which the current user belongs, pushes the display content of the terminal interaction module to the current display device, and performs split-screen display. In the embodiment, the left screen displays the content of the terminal interaction module, and the right screen displays the dynamic diffusion map of the pollutant. The embodiment further judges whether the screen projection request is unique. If the screen projection request is not unique, only the screen projection request of the person with the highest position is accepted, and at the same time, the playing speed of the dynamic diffusion map of the pollutant is adjusted to be the highest, so as to facilitate the rapid display of the diffusion situation.

[0070] The scheme of the embodiment can identify the pollution disposal action of the relevant environmental management department on site. Generally, after the action deployment is completed, the relevant work will be started. According to the moving track, it is judged whether the current user stays at a preset distance of another display device for more than a set time. The possibility of temporarily holding a meeting on site is relatively large, which indicates that a sudden event may occur on site, and the plan needs to be temporarily adjusted. At this time, the link is established to start the screen projection right, so that the relevant information can be projected to the display device when the relevant action is deployed. It is difficult to coordinate the establishment of the link for real-time screen projection of various display devices. In the embodiment, the scheme is used in special cases, so that the cost is saved and the resources are saved, and effective support is provided for the on-site disposal work.
