[0023] The present application is described in detail below with reference to specific embodiments.

[0024] Next, combine Figure 1 , taking the terminal executing the building visualization based on UE5 and BIM as an example, the building visualization system based on UE5 and BIM provided by the embodiment of the present application is introduced. For details, please refer to Figure 1 , including 3D twin model construction module, 3D twin model driving module and business data display module;

[0025] The 3D twin model construction module constructs a 3D twin model of the cell through UE5. The 3D twin model can be a 1:1 restoration of the real-time scene of the cell, and the time operation logic of the cell can be reproduced in real time in the 3D twin model, so as to display the real situation of the cell in real time in the 3D twin model.

[0026] The three-dimensional twin model driving module controls the actions and parameters of the three-dimensional twin model through a blueprint based on the data acquired in real time, thereby driving various parts of the three-dimensional twin model and updating the three-dimensional twin model in real time.

[0027] The 3D twin model driving module controls the actions and parameters of the 3D twin model through a blueprint based on the data acquired in real time, thereby driving various parts of the 3D twin model and updating the 3D twin model in real time;

[0028] Furthermore, the three-dimensional twin model includes residential buildings, garden vegetation, guard booths, community walls, parking lots, community monitoring equipment, sketches (sculptures, flower beds, rockery, fountains, seats, pavilions, pergolas, lamps, lamp posts, etc.), internal roads in the community, public transportation network around the community, and white film of buildings around the community.

[0029] Let's further describe the process of making white film:

[0030] Collect city base map remote sensing images and city building shp vector data, download high-precision city remote sensing images through BigMap or Shuijingzhu, and download city building shp vector data through OpenStreetMap; high-precision city base map remote sensing images are used to determine the building location and geographic coordinate alignment when building the digital twin city scene, and calculate the center position coordinates and scene size of the scene to create the scene base plate; city building shp vector data are used to quickly create urban white film.

[0031] Processing of urban base map remote sensing images Use GIS software to import urban base map remote sensing images, check the data source information, and record the projection coordinate system ESPG and geographic coordinate system ESPG labels of the urban base map remote sensing images; the range data in the data source information is displayed by the lower left corner coordinates (X0, Y0) and the lower right corner coordinates (X1, Y1), and the scene center point coordinates (Xp0, Yp0) are calculated using these two sets of coordinates; where Xp0 = (X0 + X1) / 2, Yp0 = (Y0 + Y1) / 2; the scene size is represented by width W and height H: H = |Y1 Y0|, W = |X1 X0|; according to the 3D modeling software, create a plane of corresponding size according to the calculated scene size (W, H), and set the plane center coordinates to the (0, 0) coordinate origin, and then export it as FBX data.

[0032] Processing urban building shp vector data Use GIS technology to produce urban building data, first import it into Blender software, then model the urban building data as a whole, so as to obtain urban building model data; import the generated urban building data and urban plane data into the Unreal Engine project file.

[0033] Furthermore, the operations performed by the three-dimensional twin model driving module include: obtaining sensor data; creating a blueprint in UE5 to control the actions and parameters of the three-dimensional twin model; configuring input nodes in the blueprint, selecting protocols and ports to ensure that the three-dimensional twin model driving module can correctly receive external data, configuring output nodes in the blueprint, packaging the data to be fed back into a preset format, and sending it to the Internet of Things through a preset protocol; analyzing the sensor data according to changes in the sensor data and updating the three-dimensional twin model based on the analysis results.

[0034] Furthermore, the parts driven by the three-dimensional twin model driving module include: community vehicle gates, indoor smoke alarms in buildings, house fire warnings, abnormal water and electricity usage equipment monitoring, community lighting systems, electric vehicle elevator entry monitoring alarms, and warnings for dogs not being leashed when walking.

[0035] Specifically, the three-dimensional twin model construction module, for example, uses UE5 to build a three-dimensional twin model that restores the real-time scene of a cell in 1:1, including equipment management, equipment component disassembly, weather scenes and time scenes.

[0036] Equipment management: quickly locate the equipment and display relevant data, such as pedestrian and vehicle flow information, equipment operating parameters, fault information, etc.

[0037] Floor disassembly: split the unit building and extract a specific floor for display.

[0038] 1. Cut the model into floors. The model of each floor must be independent.

[0039] 2. Group each layer of the model into a group with the following naming rules:

[0040] floor Naming convention B1 -1F First floor 1F Second floor 2F Third floor 3F Rooftop Roof

[0041] 3. If there are many types of models in each floor, such as detailed indoor models and floor indoor partition color blocks.

[0042] The functions that need to be performed can be grouped separately and included in the floor group.

[0043] For example, if the color blocks in the indoor area are grouped, the visibility of this group can be controlled separately in UE in the future.

[0044] The same is true for detailed indoor models. If there are many indoor models, it will consume a lot of performance. You can hide the models before layered display, and then display the detailed indoor models during layered display, etc.

[0045] The indoor floor naming rules are:

[0046] Indoor Model Group Naming convention Color blocks of the area on the negative 1 floor -1F_Area Area color blocks on the 1st floor 1F_Area

[0047] 4. After the model's hierarchy is processed, export the entire building as a DataSmith file.

[0048] The name should be the English name of the building or its full Chinese spelling.

[0049] 5. Naming and hierarchy rules examples

[0050] By default, when you left-click on the roof, the floors will rise up and be displayed in layers.

[0051] In the layered state, click on a floor and it will be pulled out for display. Click again to push it back.

[0052] In the layered state, click on the roof to restore to the default state. If there are floors that have not been pushed back in the layered state, the program will automatically reset the position of the floors and then restore to the default state of the building.

[0053] If you want to modify the click key, open the BP_SMBD_Manager blueprint, find the LineTrace area, and modify the key.

[0054] Fill in the BP_SMBD_Manager in the scene and the TestSMBDActor in the details panel with the model you want to test.

[0055] Open the BP_SMBD_Manager blueprint and find the Anykeys area and API area

[0056] The API area is a fixed API interface in the BP_SMBD_Building blueprint that can be called by the Manager.

[0057] You can connect the Anykeys pin to the corresponding API, play, and press the button to trigger the test. After the building layering function is completed, if you want to make art in the building and add details, you can make it directly in the scene. After making it, place the newly added objects in the corresponding floor Actor.

[0058] After the building layering function is completed, if you want to create art in the building and add details, you can do it directly in the scene. After production, place the newly added objects in the corresponding floor Actor.

[0059] Weather scenes: simulate and restore the effects of the real world in a natural environment (such as sunny days, cloudy days, rainy days, snowy days, etc.); and intervene through professional artistic means to make the digital twin have a better look and feel and artistic improvement based on the restoration of the real world.

[0060] Time scene: 1:1 real-time reproduction of the real-world time calculation logic, restoring the night lighting atmosphere of the community's surrounding environment, and being able to have real scene performances in different time periods during the day and night.

[0061] The 3D twin model includes: residential buildings, shops around the community, IoT devices, ground, architectural pieces, vegetation and surrounding environment, which make up the community. It has the following functions:

[0062] (1) Using the twin scene engine UE5 base, it supports basic functions such as zooming in and out, rotating the twin scene, and can present advanced scene effects;

[0063] (2) Detailed display: Through carousel or manual selection, some areas can be enlarged for partial display;

[0064] (3) Based on the basic information provided, including CAD, oblique photography, BIM and other data;

[0065] (4) The rendering effect requires the use of a next-generation real-time rendering engine to display the most realistic images;

[0066] (5) Different levels of scenes can be loaded according to the distance to control the overall rendering budget, making the entire experience process very smooth.

[0067] The three-dimensional twin model driving module drives each part of the three-dimensional twin model through the blueprint based on the real-time data. The organic connection and operation of the digital twin technology model requires the support of various production data. Including the realization of equipment functions, signal processing, guidance of model behavior, constraints of operation rules, etc. The operation and maintenance management of the community digital twin is mainly reflected in the two aspects of equipment action and spatial position. The three-dimensional structure model is linked to the physical equipment structure, and the physical space positioning and processing action data of the physical space are obtained by the positioning / action data interface. The activity monitoring service is used to drive the action of the three-dimensional twin model and the update of the three-dimensional twin model.

[0068] This system establishes the communication mechanism of the Internet of Things platform. In order to realize data interaction between models and real-time data driving, the three-dimensional twin model must establish a communication signal interface based on the operation drive data. The digital space has a flexible signal communication mechanism, which uses PLC, RFID, and TCP / IP interfaces to communicate with entities in real time.

[0069] The 3D twin model driver module performs the following operations to drive and refine the 3D twin model:

[0070] (1) Obtaining sensor data: First, using IoT technology requires obtaining sensor data and importing it into UE5

[0071] (2) Create a blueprint: Create a blueprint in UE5 to control the actions and parameter management of the corresponding model. Users can write their own logic code or modify and adjust it based on the existing blueprint template;

[0072] (3) Configure input and output nodes: Configure input and output nodes in the blueprint to connect sensor data and data fed back to the IoT. When configuring input nodes, you need to select the corresponding protocol and port to ensure that external data can be received correctly; when configuring output nodes, you need to package the data to be fed back into a specified format and send it to the IoT system through the specified protocol;

[0073] (4) Analyze feedback data and update model status: According to the changes in sensor data, analyze the data and update the relevant model status.

[0074] The parts of the model that are driven include:

[0075] 1) Community vehicle gate: When a vehicle passes by, it can automatically identify the license plate number, automatically distinguish between owners and visitors, and record the entry and exit time;

[0076] 2) Indoor smoke alarm: If there is thick smoke in the residential building, the warning will be triggered immediately

[0077] Reels, etc.

[0078] 3) Fire warning: trigger the warning immediately when a fire occurs;

[0079] 4) Equipment monitoring of abnormal water and electricity usage: For elderly people living alone who are not at home all year round, if there is abnormal water and electricity usage, an alarm can be triggered to avoid accidents;

[0080] 5) Community lighting system: All lighting facilities are automatically turned on at night, and the corridor elevator lighting is turned on according to the induction of people;

[0081] 6) Electric vehicle entering the elevator monitoring alarm: Electric vehicles entering the elevator are identified by AI and the elevator door cannot be closed

[0082] 7) Warning for dogs walking without a leash: Identified by camera;

[0083] 8) Objects thrown from high places: Identified by cameras;

[0084] The business data display module displays the data required for each dimension in the form of statistical charts, which is convenient for quickly understanding the overall and module operating status. When switching modules, the corresponding charts of the modules are also switched. In addition, the corresponding parameters and model changes can be displayed on the corresponding entity models.

[0085] The business data display module implements the above functions by connecting to the following business systems:

[0086] 1) Video surveillance system

[0087] 2) Community public safety monitoring system

[0088] 3) Community actor governance

[0089] 4) Governance of key places

[0090] 5) Community Risk System

[0091] 6) Internet of Things System

[0092] 7) Face recognition system

[0093] 8) Video surveillance system

[0094] The system also has the following functions:

[0095] 1) Promotional billboard: introduction to the community’s vision and planning, basic information such as the area’s berthing capacity, cargo capacity, transportation advantages, surrounding facilities, annual productivity, etc.

[0096] 2) One-click navigation: One-click navigation of the community area, with relevant language introduction or animation demonstration, supports multi-route and multi-dimensional navigation, and can introduce different modules in a targeted manner in the form of pop-up boxes.

[0097] 3) Multi-terminal applications: support handheld terminals, computers, as well as streaming and docking with large screens.

[0098] Here, we focus on the pixel stream display method. After setting the call information of the cell pixel stream display scene, it is packaged to form a cell display access program; the call information includes the call port number, codec format and signaling server.

[0099] Preferably, the encoding and decoding format of the cell pixel stream display scene is H264, and the signaling server adopts a remote signaling server.

[0100] The specific process is: load the Pixel Streaming plug-in;

[0101] Open the editor preferences, find "Additional startup parameters" in the "Playback" section menu, and enter AudioMixerPixelStreamingIP=localhost PixelStreamingPort=8888 to set the calling port number.

[0102] Start the signaling server, use the remote signaling server, and select H264 as the codec.

[0103] Package to form a community display access program.

[0104] Set the running information of the cell display access program. The running information includes the signaling server, running parameters and the unique access port number. The running parameters include the port number of the signaling server, program resolution and whether the program runs in full screen, etc.

[0105] The specific process includes:

[0106] Set the access port number of the cell display access program. The specific method is:

[0107] (1) Find the config.json file in the package path. Generally, the file path is X:\Package Folder\Windows\Project Name\Samples\PixelStreaming\WebServers\SignallingWebServer;

[0108] (2) Change "HttpPort" in the config.json file to "8000" and save the file to avoid port conflicts.

[0109] Set up the signaling server by finding and running the run_local.bat file.

[0110] Create a shortcut for the packaged cultural relics display access program, and add running parameters in the properties, specifically: AuditMixerforceresResX=1920ResY=1080PixelStreamingIp=localhostPixelStreamingPort=8888RenderOffScreen.

[0111] After the program is accessed according to the access port number, the cell display access program calls and displays the cell pixel flow display scene according to the calling port number, and the viewing angle can be switched freely.

[0112] From this, we can see that the display of the community model is only pushed to the personal device through the pixel stream. The community owners can check the flow of people and vehicles in the community anytime and anywhere, and make predictions in advance for their own travel conditions or abnormal conditions of their family members.

[0113] Cross-screen support: The digital twin platform needs to support cross-screen callback parameter definition to meet cross-screen parameter transmission and data linkage switching scenarios. For example, the change of a certain ID on the A screen can be monitored on the B screen. When the ID changes, the AB screens can change accordingly.

[0114] Handheld terminal support: The digital twin platform must support the direct creation of a terminal interface for remote control of handheld terminals, and the control interface can be quickly accessed by scanning a QR code. After communication between the two ends, the large visualization screen can be directly controlled.

[0115] like Figure 2 As shown, an embodiment of the present invention also provides a cell visualization method based on the system provided in Example 1, including: step S1, constructing a three-dimensional twin model of the cell through UE5, and replicating the time operation logic of the cell in the three-dimensional twin model in real time according to a preset ratio, so as to display the actual situation of the cell in real time in the three-dimensional twin model; step S2, based on the data obtained in real time by the Internet of Things, controlling the actions and parameters of the three-dimensional twin model through a blueprint, so as to drive each part of the three-dimensional twin model, and updating the three-dimensional twin model in real time to realize the dynamic simulation operation of the three-dimensional twin model; step S3, receiving data from various business systems in cell governance for analysis and integration, and transmitting the analyzed and integrated data to the three-dimensional twin model driving module in the form of statistical charts, and displaying the data of each business system in the three-dimensional twin model.
