[0024] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0026] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0027] This embodiment is mainly based on the 3D visualization scene of Unreal Engine, and encapsulates the 3D dynamic visualization of the elevator into a general elevator monitoring blueprint component. It publishes control functions such as elevator display, elevator shutdown, elevator movement, and elevator data setting; and provides parameters such as elevator shaft size, elevator car size, floor height, elevator consumption time per floor, number of floors, and elevator data window position. The elevator blueprint function can be called and the elevator parameters can be set through C++ to achieve the purpose of dynamically controlling the elevator for 3D visualization.

[0028] See also Figure 1 As shown, this embodiment provides a three-dimensional dynamic visualization method for elevator monitoring, including:

[0029] Step S101: construct a three-dimensional elevator building model through 3DMAX modeling software according to the building data, and export the data of the three-dimensional elevator building model to obtain a DataSimth file.

[0030] Specifically, in this embodiment, building data is obtained, including elevator shaft parameters, elevator car parameters, floor heights, number of floors, and window positions. The parameters required for the three-dimensional elevator building model are determined by obtaining the above-mentioned building parameters. The basic units and proportions of the modeling project are set in the 3DMAX software to ensure that all geometric shapes, sizes, and proportions are consistent with the actual building. The basic skeleton of the building is constructed, including the floor distribution and the positioning of the elevator shaft, to ensure that the size and position of the elevator shaft can adapt to the elevator car.

[0031] Install and configure the DataSmith plug-in in 3DMAX. The DataSmith plug-in is used to efficiently and seamlessly export 3DMAX models to Unreal Engine. This step ensures the correct conversion of materials and textures, as well as the preservation of model properties. Use DataSmith to export the complete building model into a format file suitable for Unreal Engine. After importing, adjust the position and orientation of the model in Unreal Engine to ensure that it is displayed correctly in the virtual environment.

[0032] Step S102: Create an elevator visualization operation level based on Unreal Engine, import the operation level into a DataSimth file, set elevator parameters, and reconstruct the elevator dynamic model through a blueprint.

[0033] Specifically, in this embodiment, an elevator visualization operation level is created based on Unreal Engine, which serves as the basic scene of the elevator model and the ring. The elevator visualization operation level exported from 3DMAX is imported into the DataSimth file using the DataSimth plug-in.

[0034] Create an elevator blueprint class in Unreal Engine. Blueprint is a visual scripting system of Unreal Engine that allows developers to write logic and functions through a graphical interface. The elevator blueprint class will encapsulate all elevator behaviors and properties, such as movement, door opening and closing, etc.

[0035] Design the 3D model of the elevator and create appropriate materials for the elevator. This includes the interior decoration, buttons, and display screens of the elevator, etc. Use the Unreal Engine material editor to adjust the glossiness, reflectivity and other properties of the elevator material to ensure the visual authenticity and attractiveness of the elevator.

[0036] Write an elevator blueprint function in the elevator blueprint class to control the movement logic of the elevator, such as ascending and descending to a specified floor. The function can calculate the moving distance and time according to the input target floor, and control the animation and speed of the elevator. This function is a conventional technical means well known to those skilled in the art. This application does not involve technical improvements to this step, and will not be described in detail here.

[0037] Set configurable parameters in the elevator blueprint, such as the elevator's maximum speed, stop floors, delayed door opening time, etc. These parameters can be dynamically adjusted while the game is running to adapt to different usage scenarios and performance requirements.

[0038] Add the created elevator blueprint instance to the created running level. This step involves placing the elevator in the correct position in the building model and ensuring that the elevator shaft is aligned with the elevator blueprint.

[0039] Package the running level into an exe file, and publish the Web video stream address through Node.js, such as WebRTC or WebSocket and other technologies to transmit video data in real time.

[0040] Through the above steps, a complete elevator dynamic model and visual operating environment can be realized, which can not only be executed locally but also displayed in real time through the network.

[0041] Step S103: Using the C++ data management program as a data bridge, the acquired real-time operation data of the elevator is pushed to the blueprint, and a Web video streaming service is published to dynamically display the real-time operation status of the elevator.

[0042] Specifically, in this embodiment, the elevator sensor data logger pushes the real-time operation data of the elevator to the C++ data management program, and the C++ data management program receives and parses the real-time operation data of the elevator to obtain the parsed elevator parameters (such as elevator ID, name, target floor, operation status, etc.). In Unreal Engine, an interface is created to receive the data sent from the C++ program, which can be extended by using HTTP requests, WebSocket connections, or directly from C++ to Unreal's custom plug-in.

[0043] The parsed elevator parameters are passed to the blueprint to update the elevator blueprint function, call the updated elevator blueprint function (including updating the current position and operating status of the elevator), and push the elevator parameters to the published Web video stream address. The address is accessed through a browser for real-time dynamic visualization.

[0044] It should be noted that in this embodiment, the real-time operation data of the elevator monitoring mainly comes from the data acquisition instrument or the sensor data collected by the Internet of Things platform. The data transmission protocol can be defined to push the real-time operation data of the elevator to the interface specified by C++. C++ then interacts with the blueprint to make a three-dimensional building model, which can show the elevator effect more intuitively and realistically, and restore the real elevator operation environment one by one. The dynamic visualization effect of the elevator is shown in the figure. Figure 2 shown.

[0045] The method described in this embodiment encapsulates the three-dimensional visualization function of the elevator into a blueprint component, which has universality and portability, and can also support expansion or transformation. It is finally published as a Web video stream address based on the server and can be accessed through a Web browser. Only an ordinary computer, tablet or mobile terminal is needed to connect to the network at any time and any location to monitor the elevator in real time, ensure the safe and smooth operation of the elevator, and greatly ensure the personal safety of the elevator passengers.
