[0039] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is for explaining specific embodiments only and is not intended to limit the scope of this application.
[0040] The embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.
[0041] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.
[0042] To facilitate understanding of this application, the relevant concepts involved in this application will be explained below:
[0043] Cockpit dashboard: A display system integrating multiple data sources, showcasing key information, charts, metrics, and real-time updates on a large screen to support decision-making and monitor business operations. Managers can gain a comprehensive overview of the company's operations from a single interface, enabling timely adjustments and optimizations.
[0044] Digital twins fully utilize data from physical models, sensor updates, and operational history to integrate multi-disciplinary, multi-physical, multi-scale, and multi-probabilistic simulation processes, completing mapping in virtual space to reflect the entire lifecycle of the corresponding physical equipment. Simply put, a digital twin is creating a digital "clone" based on a single device or system.
[0045] DOM: Document Object Model. Browsers parse HTML documents into a tree structure and define standards for accessing and manipulating HTML documents based on this structure.
[0046] JSON: A lightweight data-interchange format that is based on a subset of ECMAScript and uses a text format that is completely independent of programming languages to store and represent data.
[0047] 3D rendering component: A tool library that further encapsulates and simplifies WebGL, also known as a "3D engine". After encapsulation, all the details of WebGL are hidden, allowing front-end developers to create 3D scenes just like developing normal JS programs.
[0048] Scene: A 3D scene object can be understood as a virtual 3D scene used to represent a simulated real 3D scene in life, or a 3D world.
[0049] Camera: If you want to render a 3D scene onto a web page, you also need to define a virtual camera, just like you need a camera to take a picture in real life.
[0050] Canvas: Just as photos taken with a camera have a specific size, 3D rendering components need to define the size of the canvas (photo) that the camera outputs on the webpage. The result of a 3D rendering component rendering a 3D scene using a virtual camera and displaying it on a webpage in a browser is called a canvas.
[0051] Renderer: The renderer executes the rendering method to generate a canvas (photo) and present the 3D scene on the canvas.
[0052] Controller: Implements rotation, scaling, and preview effects through camera controls.
[0053] IndexedDB is a browser-based NoSQL database used to persistently store large amounts of structured data on the client side.
[0054] Traditional digital twin cockpit screen development solutions struggle to meet the core demands of "agile development and continuous delivery" in internet scenarios. To reduce repetitive work for developers, lower development difficulty and costs, and help business personnel quickly build digital twin cockpit screens and accelerate project delivery cycles, this application provides a dynamic rendering method for a digital twin-based cockpit screen. The following is a detailed description of this dynamic rendering method for a digital twin-based cockpit screen, in conjunction with the accompanying drawings.
[0055] See Figure 1 , Figure 1 This is a flowchart illustrating a dynamic rendering method for a cockpit large screen based on digital twins, provided as an embodiment of this application. Figure 1 As shown in the embodiment of this application, a dynamic rendering method for a cockpit large screen based on digital twins may include steps S101 to S104, which are described in detail below.
[0056] S101 renders structural objects in the target scene using a digital twin visualization editor.
[0057] In this embodiment, the user creates a target scene in the digital twin visualization editor, determines the structural object in the target scene by listening to the drag event of the user's mouse, and renders the structural object onto the visualization canvas.
[0058] In one possible implementation, users can select structure objects from a configured asset library and edit them on a visual canvas. See also Figure 2 , Figure 2 This is a partial flowchart illustrating a dynamic rendering method for a cockpit large screen based on digital twins, provided in an embodiment of this application. Figure 2 As shown in the embodiment of this application, a dynamic rendering method for a cockpit large screen based on digital twin is provided. Step S101, "rendering structural objects in the target scene through a digital twin visualization editor", may include steps S201 to S202. These steps are described in detail below.
[0059] S201, in the digital twin visualization editor, creates a target scene, selects structural objects from the asset library by listening for drag events, and renders them onto the canvas.
[0060] In this embodiment of the application, in the digital twin visualization editor, the user can create a target scene and listen to the drag event of the user's mouse to determine the structural object selected by the user in the asset library, and render the structural object onto the visualization canvas.
[0061] Specifically, the structure object includes 3D model objects and / or 2D component objects; that is, the structure object selected by the user can be one or more of 3D model objects and 2D component objects. In the target scene, by listening to the user's mouse drag events, the 3D model object selected by the user is determined from the 3D model asset library, and then rendered onto the 3D visualization canvas. Similarly, in the target scene, by listening to the user's mouse drag events, the 2D component object selected by the user is determined from the 2D component asset library, and then rendered onto the 2D visualization canvas.
[0062] S202 allows users to edit structural objects on the canvas by listening to input events and stores the edit results in the browser's IndexedDB.
[0063] In this embodiment of the application, in the digital twin visualization editor, the user's input events are listened to to edit the structural object in the canvas, thereby adjusting the attribute parameters of the structural object, and the editing result of the structural object is automatically stored in the browser's IndexedDB.
[0064] Specifically, the structure object includes 3D model objects and / or 2D component objects; that is, the structure object selected by the user can be one or more of these two types. For 3D model objects in the 3D visualization canvas, the overall scene background, environment mode, and relevant attribute data of the 3D model object (such as model position, rotation angle, scaling, shadow, etc.) are adjusted by listening to user input events in the attribute editing panel. Conversely, for 2D component objects in the 2D visualization canvas, relevant attribute parameters of the 2D component object (such as chart name, chart size, position, etc.) are adjusted by listening to user input events in the 2D chart editor.
[0065] In one possible implementation, structural objects in the asset library can be managed through a digital twin management system, supporting the updating and customization of structural objects. To this end, this application provides a dynamic rendering method for a cockpit large screen based on digital twins, which further includes the following steps:
[0066] Manage the asset repository through a digital twin management system.
[0067] In this embodiment of the application, the structure data of the structure objects stored in the asset library may include basic objects and composite objects.
[0068] Taking 3D model objects as an example, basic objects can include boxes, capsules, planes, spheres, parallel lights, point light sources, diffuse lights, etc.; composite objects can be generated using modeling tools, and 3D model files (in .glb format) can be exported from these tools. These files contain model data information (vertex positions, vertex normals, etc.) and model material information (RGB color values, model materials). The 3D model files exported from the modeling tools (such as workstations and desks for smart park scenarios, server racks and servers for smart data center scenarios, and cameras for smart branch scenarios) are stored in the digital twin management system, and the model types are distinguished (such as park, data center, branch, etc.).
[0069] S102, register a data service through the interactive data connector, and configure data mapping relationships for the structure object under the data service to generate configuration items for the structure object.
[0070] In this embodiment, the interactive data connector registers a data service. The registration items for this data service include the data service name, service type, interface URL, interface request method, interface parameters, interface request body, and interface request headers. Under this data service, corresponding data mapping relationships are configured for the structured object based on its type, thereby generating the configuration items for the resulting object. For example, for a two-dimensional component object, specified data content can be bound to it, while for a three-dimensional model object, request parameters and model event mechanisms can be bound to it.
[0071] In one possible implementation, the structure object includes a 3D model object and / or a 2D component object (i.e., the structure object can be one or more of a 3D model object and a 2D component object), wherein step S102, "configuring data mapping relationships for the structure object under the data service to generate configuration items for the structure object," may include the following steps:
[0072] For 3D model objects, bind data services to 3D model objects, and associate trigger events and model states with 3D model objects;
[0073] For two-dimensional component objects, bind the data service to the two-dimensional component object; if the two-dimensional component object is a dynamic object, establish a data mapping between the two-dimensional component object and the response field of the data service; if the two-dimensional component object is a static object, establish a data mapping between the two-dimensional component object and the preset data content.
[0074] In this embodiment, for a 3D model object, an interactive data connector binds the registered data service to the ID of the 3D model object, associating trigger events (such as model click events, model initialization events, etc.) with the model state. When a trigger event is detected, the 3D model object is controlled to enter the corresponding model state. For example, if the 3D model object is a lighting model, this lighting model is associated with model click events and lighting states. When a user clicks on the lighting model, the lighting model is controlled to enter the corresponding lighting state. After completing the association between the trigger event and the model state, the association is stored in the configuration items of the 3D model object.
[0075] For two-dimensional component objects, the registered data services are bound to the ID of the two-dimensional component object through an interactive data connector. If the two-dimensional component object is a dynamic object, the response fields in the response body returned by the data service are mapped to the two-dimensional component object. For example, if the two-dimensional component object is a chart comparing the construction years of buildings in the park, the X-axis of the chart is mapped to the "Building Name" field in the response body, and the Y-axis of the chart is mapped to the "Construction Year" field in the response body. If the two-dimensional component object is a static object, the data mapping can be completed by importing existing data or by customizing data content in the interactive data connector. After the data mapping is completed, the data mapping relationship can be stored in the configuration items of the two-dimensional component object.
[0076] S103: The digital twin configuration builder assembles the registration items, structure objects, and configuration items of the data service into a configuration file for the target scene, and serializes it into a JSON data structure and stores it in the digital twin management system, so that the digital twin management system can generate web page links for the target scene based on the JSON data structure.
[0077] In this embodiment, the digital twin configuration builder categorizes and processes structure objects, data service registration items, structure object configuration items, and system parameters stored in the browser's IndexedDB, assembling them into a complete configuration file for the target scenario. This configuration file is then serialized into a JSON data structure. This JSON data structure is stored in the digital twin management system via periodic requests or manual saving. The digital twin management system then generates webpage links corresponding to the target scenario based on this JSON data structure.
[0078] In one possible implementation, a digital twin management system can be used to manage the version of JSON data structures in different scenarios, supporting comparison of all versions and restoration of any historical version. In this regard, an embodiment of this application provides a dynamic rendering method for a cockpit large screen based on digital twins, which further includes the following steps:
[0079] Version control of JSON data structures is achieved through a digital twin management system.
[0080] In this embodiment, after obtaining the JSON data structure for the target scenario, the digital twin management system compares it with previously stored historical versions of the JSON data structure to determine the differences in the current version, and records the relevant modification time and user. This allows for the management of all versions of the JSON data structure for the target scenario.
[0081] S104 accesses web page links through the digital twin scene parser to download JSON data structures, deserializes them into configuration files, parses the configuration files, and renders and displays the target scene on the large screen page.
[0082] In this embodiment, the digital twin scene parser accesses the webpage link of the target scene via a browser, obtains the application identifier on the page, downloads the corresponding JSON data structure, and deserializes the JSON data structure into a configuration file for the target scene. All content in the configuration file is parsed to form reconfigurable configuration entries. The scene is then fully restored according to these configuration entries. In other words, the JSON data structure is deserialized into registration items, structure objects, and configuration items for a data service. The 3D model objects and 2D component objects within the structure objects are then classified and calculated, thereby enabling the dynamic rendering of the page's 3D model objects, 2D component objects, and other data on a large-screen page.
[0083] Specifically, the two-dimensional component object is treated as a two-dimensional component attribute. The digital twin scene parser performs secondary rendering on the two-dimensional component object according to the two-dimensional component parsing method, and creates the page DOM structure and chart styles through JS. For example, a component tree is constructed using configuration parameters such as component ID and component style. Combined with the style tree, the page is rendered. The interactive data connector sends a request to the data service based on the data service's registration items and the configuration items of the two-dimensional component object to obtain the data content of the data mapping. The digital twin scene parser then populates the two-dimensional component object with this data content.
[0084] The 3D model objects are categorized as 3D component attributes. The digital twin scene resolver initializes the 3D scene, camera, renderer, and controller with 3D rendering components based on the configuration items of the 3D model objects. It defines the canvas size for camera rendering output and inserts the canvas into the specified HTML element to render the 3D model objects. Upon detecting trigger events associated with the 3D model objects, the digital twin scene resolver controls the 3D model objects to enter the corresponding model states.
[0085] In addition, system parameters in the configuration file are classified as system-level attributes, such as application identifiers and page parameters.
[0086] Based on the above description, the embodiments of this application provide a dynamic rendering method for a cockpit large screen based on digital twins. The digital twin visualization editor based on the B / S architecture performs dynamic rendering of 3D model objects and 2D component objects by parsing the configuration file generated by the visualization editor, which reduces the development difficulty and time cost, helps users quickly build a digital twin cockpit large screen, and speeds up the project delivery cycle.
[0087] The above describes a dynamic rendering method for a cockpit large screen based on digital twins provided by embodiments of this application. The following will describe the system that performs the above-described dynamic rendering method for a cockpit large screen based on digital twins.
