[0055] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0056] like Figure 1 As shown, a preferred embodiment of the present invention provides a water quality dynamic rendering method, comprising the following contents:

[0057] Step S1: importing water environment monitoring data and river system data into the server, wherein the water environment monitoring data includes location information of monitoring points and water quality monitoring data;

[0058] Step S2: Associating river system data with monitoring points based on location information;

[0059] Step S3: Calculate the water quality category, water quality concentration level and corresponding rendering color of each monitoring point based on the imported water quality monitoring data, and store the data calculation results in the achievement library of the server;

[0060] Step S4: The client loads the river system data file from the server and caches it locally, and retrieves the data calculation results from the server's results library;

[0061] Step S5: Rendering the water quality of the water system according to the correlation between the river system data and the location information of the monitoring points and the data calculation results;

[0062] Step S6: Display the water quality rendering result.

[0063] It can be understood that the execution order of step S2 and step S3 can be swapped.

[0064] It can be understood that in the water quality dynamic rendering method of this embodiment, after the water environment monitoring data and river system data are imported into the server, the river system data is associated with the location information of the monitoring point, so that in the subsequent water quality rendering stage, it is possible to quickly and accurately identify which river systems have monitoring data, which is conducive to improving the efficiency of water quality rendering. Then, based on the imported water quality monitoring data, the water quality category, water quality concentration level and corresponding rendering color of each monitoring point are calculated, and the data calculation results are stored and written into the server's achievement library. When the client needs to perform water quality rendering, it only needs to load the river system data file from the server and cache it locally, and retrieve the data calculation results from the server's achievement library, and then perform water quality rendering on the water system based on the association between the river system data and the location information of the monitoring point and the data calculation results. Finally, the water quality rendering results are displayed. The entire data calculation and processing process is concentrated on the server, with high data processing efficiency, and the data calculation results are packaged and stored in the results library. When the client needs real-time rendering later, it can directly retrieve the corresponding data calculation results from the results library. There is no need to perform a large amount of calculations during the rendering process, and a large amount of data communication with the server. In the subsequent water quality rendering process, the water system data does not need to be repeatedly loaded from the server, which greatly reduces the number of interactions with the server and improves the rendering efficiency. Moreover, in the water quality rendering stage, based on the correlation between the river system data and the location information of the monitoring points, the river system with monitoring data can be quickly and accurately identified, and the river system without monitoring data will not be rendered, which further improves the rendering efficiency. In addition, the entire water quality rendering process is relatively simple, and there is no need to use third-party plug-ins or background systems for processing.

[0065] It can be understood that in step S1, after the environmental monitoring application system is built in the server, water environment monitoring data and river system data are imported into the server, wherein the water environment monitoring data includes the location information of the monitoring points and water quality monitoring data, and the river system data includes the location information of the river system, river direction information, etc. Among them, the way of importing data can be manual import, or access to the monitoring data of the automatic monitoring station through a standard protocol. In addition, after importing the water system data file into the server, the server converts the water system data file into a JSON file and compresses and packages it. When the client loads the water system data from the server, it directly loads the entire JSON file without loading the water system data one by one, which improves the data transmission efficiency and reduces the number of read accesses.

[0066] It is understandable that Figure 2 As shown, in another embodiment of the present invention, the water quality dynamic rendering method further includes the following contents after importing the water environment monitoring data into the server:

[0067] Step S12: using a multi-table multi-point approach to store the imported water environment monitoring data.

[0068] When multiple data sources continuously import data in real time, the server uses a multi-table and multi-point approach to store data, which can speed up the efficiency of data writing and storage.

[0069] It can be understood that in step S2, the river system data is associated with the monitoring points based on the location information, so that each monitoring point can be assigned to a different river system, so that in the subsequent water quality rendering stage, it is possible to quickly and accurately identify which river systems have monitoring data, which is conducive to improving the efficiency of water quality rendering.

[0070] It can be understood that in step S3, the water quality category of each monitoring point can be calculated according to the water quality monitoring data of each monitoring point, for example, it belongs to Class I water or Class II water, and different rendering colors are preset for different water quality categories. There are six colors in total, corresponding to the water quality categories of Class I water, Class II water, Class III water, Class IV water, Class V water and inferior Class V water. At the same time, the water quality concentration level can also be calculated. Similarly, different rendering colors are preset according to different water quality concentration levels. In addition, the data calculation results are assembled and packaged and stored in the results library. When the client needs to render water quality, the data calculation results can be directly retrieved from the results library without frequent data communication with the server, which greatly improves the rendering efficiency. Among them, the calculation method of the water quality concentration level can be to set N levels by custom setting, and then divide N intervals based on the maximum and minimum values ​​of the obtained water quality concentration data. The way of dividing the interval is to divide it into several equal parts by linear interpolation. When the concentration value falls between a certain equal part, it is expressed by this level.

[0071] It can be understood that in step S4, when the client needs to perform real-time rendering and display, the back-end service data interface is called through Ajax, the river system file is loaded from the server and cached locally, and the water system data does not need to be repeatedly loaded from the server in the subsequent water quality rendering process, which greatly reduces the number of interactions with the server and improves the rendering efficiency. At the same time, the data calculation results are directly called from the results library, eliminating frequent data communications with the server, further improving the rendering efficiency.

[0072] It is understandable that Figure 3 As shown, the step S5 specifically includes the following contents:

[0073] Step S51: Filter out river systems with water quality monitoring data based on the correlation between river system data and monitoring points;

[0074] Step S52: Divide each screened river system into multiple river sections;

[0075] Step S53: matching each river section with the associated monitoring point in a manner of the shortest distance;

[0076] Step S54: Rendering the water quality of each river section based on the data calculation results of the successfully matched monitoring points;

[0077] Step S55: splicing the water quality rendering results of each river section into the water quality rendering result of the entire river system.

[0078] Specifically, based on the correlation between the river system data and the monitoring points set in step S2, it is possible to quickly and accurately screen out which river systems have monitoring data, and not to render water quality for those river systems without monitoring data, which is conducive to improving the efficiency of water quality rendering. At the same time, it is also possible to accurately determine the attribution relationship between the monitoring points and the river system, that is, which river system the monitoring point should belong to, thereby ensuring the accuracy of the water quality rendering result. Then, each river system with monitoring data screened out is divided into multiple river sections, and the nearest monitoring point is selected for each river section as a matching point, that is, the distance is calculated according to the river section coordinates and the longitude and latitude coordinates of each monitoring point, and the one with the smallest distance value is selected as the matching point. Then, the data calculation results corresponding to the matching point (i.e., water quality category, water quality concentration level and corresponding rendering color) are used to render water quality for each river section, wherein the river section that is not matched to the point is not rendered. Finally, the water quality rendering results of all river sections are spliced ​​together to form the water quality rendering results of the entire river system.

[0079] It is understandable that Figure 4As shown, in another embodiment of the present invention, the water quality dynamic rendering method further includes the following contents:

[0080] Step S7: When the server identifies that the monitoring data of a certain monitoring point is updated, the updated monitoring data is pushed to the client;

[0081] Step S8: The client renders the river section corresponding to the monitoring point separately.

[0082] During the real-time rendering process, when the server recognizes that the monitoring data of a monitoring point has been updated, it will push the updated monitoring data of the monitoring point to the client. After receiving the updated data, the client only performs a separate rendering update for the river section corresponding to the monitoring point, without the need to render and update the entire river system, thereby achieving minimum request interaction and greatly improving the real-time rendering efficiency.

[0083] Specifically, after the first rendering, in the application scenario of playing by timeline or real-time update of water quality monitoring data, when the water quality monitoring data changes, only the river section with the changed water quality monitoring data needs to be disassembled and then rendered. By flexibly disassembling the river section for rendering, the rendering efficiency of large-area rendering can be effectively improved.

[0084] In addition, if Figure 5 As shown, another embodiment of the present invention further provides a water quality dynamic rendering system, preferably using the above-mentioned water quality dynamic rendering method, the water quality dynamic rendering system comprises:

[0085] A data import module is provided on the server side and is used to import water environment monitoring data and river system data, wherein the water environment monitoring data includes location information of monitoring points and water quality monitoring data;

[0086] The association module is set on the server side and is used to associate the river system data with the monitoring points based on the location information;

[0087] The data calculation module is set on the server side and is used to calculate the water quality category, water quality concentration level and corresponding rendering color of each monitoring point based on the imported water quality monitoring data, and store the data calculation results in the server's achievement library;

[0088] The data loading module is set on the local client and is used to load the river system data file from the server and cache it locally, and retrieve the data calculation results from the server's results library;

[0090] The display module is set on the local client and is used to display the water quality rendering results.

[0091] It can be understood that the water quality dynamic rendering system of this embodiment, after importing water environment monitoring data and river system data into the server, associates the river system data with the location information of the monitoring point, so that in the subsequent water quality rendering stage, it can quickly and accurately identify which river systems have monitoring data, which is conducive to improving the efficiency of water quality rendering. Then, based on the imported water quality monitoring data, the water quality category, water quality concentration level and corresponding rendering color of each monitoring point are calculated, and the data calculation results are stored and written into the server's achievement library. When the client needs to perform water quality rendering, it only needs to load the river system data file from the server and cache it locally, and retrieve the data calculation results from the server's achievement library, and then perform water quality rendering on the water system based on the association between the river system data and the location information of the monitoring point and the data calculation results. Finally, the water quality rendering results are displayed. The entire data calculation and processing process is concentrated on the server, with high data processing efficiency, and the data calculation results are packaged and stored in the results library. When the client needs real-time rendering later, it can directly retrieve the corresponding data calculation results from the results library. There is no need to communicate a lot of data with the server during the rendering process, and in the subsequent water quality rendering process, the water system data does not need to be repeatedly loaded from the server, which greatly reduces the number of interactions with the server and improves the rendering efficiency. Moreover, in the water quality rendering stage, based on the correlation between the river system data and the location information of the monitoring points, the river system with monitoring data can be quickly and accurately identified, and the river system without monitoring data will not be rendered, which further improves the rendering efficiency. In addition, the entire water quality rendering process is relatively simple, and there is no need to use third-party plug-ins or background systems for processing.

[0092] It can be understood that the water quality dynamic rendering system also includes:

[0093] The data storage module is arranged on the server side and is used to store the imported water environment monitoring data in a multi-table and multi-point manner.

[0094] When multiple data sources continuously import data in real time, the data storage module uses a multi-table and multi-point method to store data, which can speed up the efficiency of data writing and storage.
