Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

Obtain warning information, display it in two dimensions on the structural mechanics information dynamic visualization platform through a pop-up window, and construct a warning information cloud map based on the warning information and display it on the structural mechanics information dynamic visualization platform.

[0059] It can be understood that this embodiment is based on two forms of structural response visualization means, namely dynamic cloud maps and deformation animations, to achieve dynamic visualization of mechanical information time-history cloud maps during the service process of the structure under different loads, proposes a structural engineering parameter visualization method, and builds a complete path for structural engineering parameter calculation, extraction, analysis and display, and achieves dynamic visualization of cloud maps of different engineering parameters of the structure under external loads during the service process of the structure, proposes a structural safety information early warning method, provides a structural early warning information storage, extraction and display method, and achieves real-time safety early warning display of structural mechanical information.

[0060] Preferably, step S1 includes:

[0061] Adopting Vue+Springboot+Flask framework, a dynamic visualization platform for structural mechanics information is built based on B / S model;

[0062] Through the router command under the Vue framework, different routing paths are set for different interfaces of the structural mechanics information dynamic visualization platform;

[0063] MySQL 2019 is used as the historical mechanics information database management system of the structural mechanics information dynamic visualization platform, Navicat is used as the historical mechanics information database visualization interface of the structural mechanics information dynamic visualization platform, and IDEA is used as the historical mechanics information database management and access interface of the structural mechanics information dynamic visualization platform.

[0064] The Reids database is used as the real-time mechanical information database of the structural mechanics information dynamic visualization platform to store real-time information.

[0065] It can be understood that step S1 includes architecture design, system function interaction design, database construction for structural historical mechanical information, and database construction for structural real-time mechanical information.

[0066] The specific architecture design is:

[0067] The visualization platform built in this step is based on a B / S model, specifically a web-based visualization platform. The web architecture is generated using the Vue, Springboot, and Flask frameworks. Vue is used to implement web functionality and information display, while Springboot and Flask are used to build the server module, which stores, processes, and transmits the transmitted structural mechanics information.

[0068] The specific system function interaction design is as follows:

[0069] To achieve click-to-switch between different interfaces, the router command in the Vue framework is used to set different routing paths for different interfaces. By properly configuring routing rules, when the user enters a specific web page path in the browser address bar or clicks a page link, the router can accurately locate and load the corresponding content.

[0070] The construction of a database for structural historical mechanical information is as follows:

[0071] This study uses MySql 2019 as the database management system, Navicat as the database visualization interface, and IDEA as the database management access interface. The data tables included are the mechanical information table and the mechanical information warning table.

[0072] The construction of a database for real-time structural mechanical information is as follows:

[0073] This paper chooses to use the Reids database to store real-time information. The database runs on the Linux operating system of the server port; the data tables included are the mechanical real-time information table and the mechanical real-time warning information table.

[0074] Preferably, step S2 includes:

[0075] Parse the node response data in the Abaqus odb file, determine the structural response data, and transmit the structural response data to the structural mechanics information dynamic visualization platform through the http protocol;

[0076] Obtain the node data processed by Abaqus, and use the node data as a benchmark to associate the node data with the triangular face vertices of the web page model through the establishment of an index mechanism, and establish a mapping relationship between the web page model and the response data;

[0077] Mapping the structural response data to the corresponding nodes of the web page grid model according to the mapping relationship;

[0078] The numerical array of nodes is obtained through Abaqus calculation;

[0079] According to the size of the numerical array, the degree of node deformation is measured by the normalizedDisplacement variable;

[0080] Render different colors for different normalizedDisplacement variable sizes;

[0081] Use the setRGB function to assign color to the node, and use setAttribute to implement patch color rendering to complete patch color cloud rendering;

[0082] Determine the structural response cloud map at the current moment based on the node response mapping results and the patch color cloud map rendering results;

[0083] The structural response cloud maps at different times are superimposed in sequence at preset time intervals to generate a coherent dynamic picture.

[0084] It can be understood that step S2 includes obtaining structural response data, deforming web page components, rendering facet colors, and generating response animations.

[0085] The specific acquisition of structural response data is as follows:

[0086] An automated script is written using Python code to parse the node response data in the Abaqus odb file, where "U" represents node displacement and "A" represents node acceleration. The extracted and processed structural response data is then transmitted to the front-end web interface via the http protocol.

[0087] The web page component deformation is as follows:

[0088] Obtain the node data processed by Abaqus, use it as a benchmark, and establish an indexing mechanism to associate the node data with the triangle patch vertices of the web page model. Then, establish a mapping relationship between the web page model and the response data, and accurately map the grouped node response data to the corresponding nodes of the web page mesh model, such as Figure 2 shown.

[0089] The specific color rendering of the patch is:

[0090] Abaqus calculates the node's numerical array, obtaining its maximum value (Dismax) and minimum value (Dismin). The variable normalizedDisplacement is used to measure the node's deformation. Different color rendering methods are used to describe the structural node's response. The setRGB function is used to assign node colors, and setAttribute is used to render the meshes in color.

[0091] The response animation is generated specifically as follows:

[0092] Through node response mapping and patch color cloud rendering, we can obtain the response cloud map of the structure at a specific moment, which can intuitively present the response distribution of the structure at a specific moment. When constructing a structural response animation, the structural response cloud maps at different moments need to be superimposed in sequence at a predetermined time interval to generate a coherent dynamic picture. In terms of the technical solution for implementing animation, the Tween.js function library can be introduced to take advantage of its advantages in animation control to complete smooth switching between different frames. At the same time, the time interval between frames is reasonably set, and the requestAnimationFrame function is used to perform callback operations between different frames.

[0093] Preferably, step S3 includes:

[0094] Call Openseespy to perform structural analysis, collect operation process and result data with the help of http protocol, and pre-process the operation process and result data;

[0095] Transfer the preprocessed data to the front-end Vue web page module;

[0096] Based on the pre-processed data, the values ​​of the engineering parameter data of the structural components at a specific moment are accurately extracted from the time history data;

[0097] The engineering parameter data is color graded according to the numerical range of the engineering parameter data through the Three.Color function;

[0098] Construct a mapping relationship between structural components and corresponding colors based on the grading results;

[0099] Complete the color rendering of engineering parameter data based on the mapping relationship between structural components and corresponding colors;

[0100] Based on the rendering results, the Tween.js function library is used to achieve smooth switching between different analysis steps, and the engineering parameter response animation is generated through the preset time interval between frames;

[0101] Use the requestAnimationFrame function to perform callback operations between different analysis steps on the engineering parameter response animation;

[0102] The visualization function of echarts controls is used to display engineering parameter response animations in the structural mechanics information dynamic visualization platform.

[0103] It can be understood that step S3 includes engineering parameter data extraction, engineering parameter color rendering, engineering parameter response animation generation and engineering parameter data visualization.

[0104] The specific extraction of engineering parameter data is as follows:

[0105] Structural engineering parameters are obtained through Openseespy, and the server calls Openseespy for structural analysis. The operation process and result data are collected and pre-processed with the help of http protocol, and then the processed data is transmitted to the front-end Vue web page module.

[0106] The specific engineering parameter color rendering is:

[0107] Accurately extract the engineering parameter values ​​of structural components at specific moments from time-history data. Next, use the Three.Color function to assign color grading to the engineering parameter values ​​based on their numerical ranges, mapping different numerical ranges of the engineering parameter to specific color grades. Based on the grading results, a mapping relationship between structural components and corresponding colors is constructed.

[0108] The specific generation of engineering parameter response animation is as follows:

[0109] The Tween.js library is introduced to achieve smooth switching between different analysis steps. At the same time, the time interval between frames is reasonably set, and the requestAnimationFrame function is used to perform callback operations between different analysis steps to achieve the generation of project parameter response animation.

[0110] The specific visualization of engineering parameter data is as follows:

[0111] The engineering parameter data is obtained through step S31, and the node data is extracted in a classified and step-by-step manner using the Python language. The extracted data is transmitted to the web interface through the http protocol, and converted into an array form on the web interface for subsequent visualization processing. With the help of the visualization function of the echarts control, the data is intuitively displayed on the web interface.

[0112] Preferably, step S4 includes:

[0113] Use the menuData function to monitor the monitoring data from Redis in real time;

[0114] Determine early warning information from monitoring data;

[0115] According to the warning information, use the setoutTime function to set the preset time interval to update the warning information dynamic table;

[0116] Use the alert function to display the warning information in a pop-up window and store the warning information in the historical warning information database;

[0117] Analyze the data output by the mechanical simulation software to determine whether the structural mechanical information exceeds the limit;

[0118] A color grading mechanism is used to establish a corresponding color grading mapping system for normal and over-limit states;

[0119] The corresponding structural components displayed on the web page are assigned colors according to the color grading mapping system and the structural mechanics information status.

[0120] It can be understood that step S4 includes two-dimensional display of warning information and cloud map display of warning information.

[0121] The two-dimensional display of early warning information is as follows:

[0122] The webpage display module uses dynamic tables and pop-up windows to present warning information in a two-dimensional format. By writing the menuData function, the system can monitor monitoring data transmitted from Redis in real time and filter out warning information. Furthermore, the setoutTime function is used to set the dynamic table to update every second to ensure data timeliness. An alert function is written to display warning information in a pop-up window and store the warning information in the historical warning information database.

[0123] The early warning information cloud map shows the following:

[0124] Cloud chart construction utilizes a color grading mechanism. Data output from the mechanical simulation software is analyzed to determine if the structural mechanical information exceeds limits. A corresponding color grading mapping system is established for both normal and exceeded data states, and specific colors are assigned to the corresponding structural components displayed on the webpage.
