[0024] Please refer to Figures 1 - 3 , a blockchain visualization method based on rural data provided by the present invention, includes: S101: Obtain the basic data of the target rural area, classify the obtained data sets according to the fields to which the basic data belongs to obtain several groups of data sets, and generate several target plates to be visualized according to the divided data sets. The target plates include an environmental visualization plate, an economic visualization plate and a people's livelihood visualization plate; In this embodiment, the fields to which the basic data belongs are divided into three major plates, including the environment, the economy and the people's livelihood. Specifically, how to classify can obtain different classification results according to different standards set by those skilled in the art, which is a free choice for those skilled in the art, and the present invention will not describe it in detail.

[0025] Generating the environmental visualization plate includes writing environmental data, and the environmental data includes soil humidity data, soil pH data, meteorological data, PM2.5 data and temperature data; Generating the economic visualization plate includes writing economic data, and the economic data includes per capita GDP data, industrial data, forest land economic evaluation data, foreign investment data and logistics warehousing data; Generating the people's livelihood visualization section includes writing people's livelihood data. The people's livelihood data include population growth rate data, population age structure data, pension data, villagers' credit data and people's livelihood project data. The people's livelihood project data can be rural infrastructure data, rural water and electricity project data, etc.

[0026] S102: Obtaining a request instruction from the user end and the network bandwidth of the user end, establishing a display mode selection model, outputting a selection index through the display mode selection model based on the network bandwidth of the user end and basic attributes of the target plate, and selecting a current visualization display mode based on the selection index, wherein the visualization display mode includes link display or map display in the initial interface; In this embodiment, two visual display methods are provided. One is the common link display, that is, obtaining the keywords of the target section, and displaying the link with the keyword as the title on the initial interface, and establishing a connection between the keyword and the content to be displayed in the target section.

[0027] When reflected to the specific user end, only the keywords are displayed. After clicking the keyword, the content connected with the keyword is transmitted between the server end. The advantage of this display is that it puts less pressure on the network bandwidth of the user end and can be browsed quickly, but it is not intuitive enough.

[0028] Map display includes dividing the target village into regions to create a GIS map, which is displayed in the initial interface in the form of a GIS map. Several blank target blocks are established in each region, and the data sets in each target block are divided according to the region to which they belong. The divided data sets are written into the blank target blocks of the corresponding regions.

[0029] When it comes to the specific user side, by clicking on an area in the GIS map, a target section about that area will appear. Each target section stores the corresponding basic data. If the user wants to read the data of a section, they can directly click to view it. The advantage of this display is that you can more intuitively know the location of the basic data you want to obtain, but the GIS map puts a lot of pressure on the network bandwidth of the user side.

[0030] Therefore, this embodiment provides a display mode selection model, which comprehensively considers the current user terminal situation and provides a more reasonable selection mode.

[0031] S103: If the currently selected display mode is link display, determine whether the current request instruction is the first access, if not, respectively obtain the number of times each target block in the current user terminal is clicked, and display the target blocks in descending order according to the number of times each target block is clicked; In this embodiment, the display method of each target section is analyzed. If the current request instruction is not the first access, the click times of each section can be obtained according to the historical browsing records of the user terminal, so as to intuitively know the browsing preferences of the current user and enable the user to quickly obtain the content they want.

[0032] S104: If so, obtain the data attributes of each target section, establish an evaluation model, output the evaluation value through the evaluation model with the data attributes of each target section, and sort based on the evaluation value of the target section to output the display order of the target section.

[0033] For the user terminal that accesses the background server for the first time, since there is no historical data, it is necessary to evaluate the content of each target section based on the situation of this village, and display the target section starting from the first row of the first page of the user terminal in the order of the evaluation results.

[0034] The method provided by the present invention mainly includes obtaining the basic data of the target village, classifying the basic data according to the fields to obtain several grouped data sets, generating several target sections to be visualized according to the divided data sets, establishing an evaluation model, outputting the evaluation value through the evaluation model with the data attributes of each target section, and sorting based on the evaluation value of the target section to output the display order of the target section. Through the above method, according to the user's operation or the analysis of rural data, a relatively reasonable display method is given, which can enable the user terminal to display the content that the user can quickly reach the content they want to browse, or highlight the content to be displayed, thereby improving the browsing efficiency to a certain extent and obtaining effective information for the user in a timely manner.

[0035] An exemplary implementation manner of the present invention further includes: S201: If the current selected display method is map display, set the retrieval time limit range, and obtain the target text data announced on the government official website of the village within the retrieval time limit range; Among them, the retrieval time range in this solution specifically refers to a range of the announcement release date. For example, in this embodiment, it is necessary to obtain the government official website announcements from October 2024 to January 2025, then October 2024 to January 2025 is the retrieval time limit range of this solution. Regarding obtaining the target text data, technologies such as optical character recognition can be used to obtain the text to be obtained.

[0036] S202: Set keywords for the environmental visualization section, economic visualization section, and people's livelihood visualization section respectively, retrieve based on several keywords in the target text data to obtain the keyword occurrence frequency, and output the total associated frequency of the corresponding target section according to the target section to which the keyword belongs; Among them, for the keywords related to the environmental visualization section, economic visualization section, and people's livelihood visualization section respectively, those skilled in the art can set them by themselves. For example, the keywords related to the environmental visualization section can be temperature, pollution, humidity, etc. Then, count the frequencies of the occurrences of these keywords and summarize and record them separately under each target section to obtain the frequencies of the occurrences of the keywords for the target section, that is, the total associated frequency for each target section.

[0037] S203: Establish a highlighted area judgment model, and based on the total associated frequency of the target section and the basic data within the target section in the area, output the judgment index for each area through the highlighted area judgment model, and sort the judgment indexes. S204: Set the display brightness of different brightness values of the same color for each area according to the sorting result of the judgment index.

[0038] According to the above solution, based on the target text data obtained from the government official website announcements, through keyword statistics, it can be reflected the emphasis of the current rural area on the environment, economy or people's livelihood. Furthermore, through the highlighted area judgment model, a judgment on the emphasis of each area is made, reflecting the strength or weakness of the relevance of each area to the current rural government announcements. Specifically, on the visualization display interface, each area is marked in different brightness values of the same color, highlighting the differences between each area, making it more intuitive for users to the current GIS map visualization interface.

[0039] In an exemplary implementation manner of the present invention, in this embodiment, some data is not convenient to be opened to the public and can only be opened to local users of the current rural area. Therefore, it is necessary to encrypt some data and verify whether to open the permission through the accounts of local users. Specifically, it includes: Encrypt the target data and generate encrypted data. The target data includes soil humidity data and soil pH data for the environmental visualization section, forest land economic assessment data for the economic visualization section, and villagers' credit data for the people's livelihood visualization section. Judge whether the user terminal corresponding to the current request instruction is a local user of the target rural area. If it is a local user, when receiving a request instruction to view encrypted data, record the user information of the current user terminal and display the encrypted data. If it is not a local user, when receiving a request instruction to view encrypted data, refuse access.

[0040] Furthermore, the encryption includes: Process the target data through the AES encryption algorithm to obtain a random encryption sequence, and define the sub-key matrix of all target data.

[0041] In the formula, is the th-order random encryption sequence, is the number of elements contained in the key matrix, is the encryption function.

[0042] Summarize all sub-key matrices to generate a mixed key matrix, and perform operations on the mixed key matrix through the AES encryption algorithm to obtain the ciphertext and the session key; When the client that recognizes the request instruction for viewing encrypted data is a local user, the session key is sent to the current client at the same time, the session key is decrypted through the ECC private key, and the ciphertext is decrypted through the decrypted session key to obtain the target data.

[0043] Secondly, when encrypting and decrypting the AES session key, the receiving end must draw an appropriate elliptic curve and synchronize it with the randomly selected private key to the sender. After combining a random integer, the sender can calculate two points by combining the ECC algorithm.

[0044]

[0045] In the formula, and are respectively two points on the ellipse, , and are respectively three different sub-key matrices, is a known point, is a random integer, is the public key, is the base point on the ellipse.

[0046] In the digital signature stage of the hybrid encryption algorithm, use the secure Hash function to obtain the hash function corresponding to the original data, and then combine the parameters generated based on the elliptic curve, the randomly selected integer, and a large prime number to complete the digital signature.

[0047] An exemplary embodiment of the present invention shows that the display mode selection model includes: Obtain the basic attributes of the target plate, and the basic attributes include the number of basic data in the target plate, the total data size value when the target plate is displayed in a map, and the total data size value when the target plate is displayed in a link; When the total data size value when the target plate is displayed in a map is less than the total data size value when the target plate is displayed in a link;

[0048] Then when , select the initial interface to be displayed in a map, and when When, select the initial interface for link display; In the above model, considering that the environmental visualization section and the economic visualization section will have better effects when displayed on a map, so is added, that is, a floating and changing calculation weight. When and increase in value, the whole will decrease, then it is more inclined to map display, which can be set according to specific situations.

[0049] When the total data size value when the target section is displayed on a map is greater than or equal to the total data size value when the target section is displayed by link, then select the initial interface for map display; Since the display effect through the GIS map is better, if the total data size value when the target section is displayed on a map is greater than or equal to the total data size value when the target section is displayed by link, then directly select map display.

[0050] In the formula, is the network bandwidth value of the user side, is the total data size value when the target section is displayed on a map, is the number of basic data in the environmental visualization section, is the number of basic data in the economic visualization section, is the total number of basic data, is the judgment threshold.

[0051] An exemplary implementation of the present invention, establishing an evaluation model includes: The data attributes include text attributes, image attributes and video attributes, and calculation weights based on the data attributes are set for the environmental visualization section, the economic visualization section and the people's livelihood visualization section respectively;

[0052] In the formula, is the evaluation value, is the calculation weight of the th target section regarding the data attribute as text attribute, is the calculation weight of the th target section regarding the data attribute as image attribute, is the calculation weight of the th target section regarding the data attribute as text attribute, is the th number of the target section regarding the data attribute as text attribute, is the th number of the target section regarding the data attribute as image attribute, is the number of target plates of the type with video attribute in terms of data attributes.

[0053] In this embodiment, if , the first type of target plate is the environmental visualization plate. Considering that the environmental visualization plate may have better display effects through pictures, then , the text effect is secondary, and the video effect is poor. , , and the remaining target plates can be set in this way. Those skilled in the art set calculation weights under a unified standard, and finally obtain an objective evaluation value for comparison.

[0054] Secondly, in this embodiment, sort in descending order according to the size of the evaluation value, and display the target plates row by row starting from the first row of the first page of the user side according to the sorting result.

[0057] Among them, can also be understood as a calculation weight regarding emphasis. The sum of the calculation scores of several target plates in one area outputs the judgment index of the current area.
