BRIEF DESCRIPTION OF THE DRAWINGS

[0057] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present invention.

[0058] Figure 1 This is a flowchart of the tobacco warehouse management method based on digital twins. DETAILED DESCRIPTION

[0059] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0060] Figure 1 The figure is a flowchart of a tobacco warehouse management method based on digital twins. In an embodiment of the present invention, a tobacco warehouse management method based on digital twins includes:

[0061] Step S100: Acquire building data of the logistics park, perform three-dimensional modeling on the logistics park, and obtain a park model;

[0062] 3D modelers model 3D models and application scenarios based on data collected on site and existing materials. Determine rendering pipeline with Unity. Model and render the entire logistics park at 1:1 scale using 3D modeling engine. Inform relevant personnel to review and export optimized models as .FBX format scene models and building model files, with textures, materials, and animations. Import the exported .fbx files into Unity and modify the import format as needed. Unity developers use editor tools to adjust and optimize art resources.

[0063] Step S200: acquiring on-site data of the logistics park based on a collection device, converting the on-site data into rendering values, and inserting the data into a park model;

[0064] The detection uses a variety of sensor devices such as thermal imagers, optical sensors, and monitoring cloud platforms to collect real-time information such as temperature, humidity, gas, and light in the warehouse, and reflect these data in real time to the digital model through digital twin technology. This model can reflect various situations in the warehouse, helping managers to quickly understand the operating status of the warehouse and take corresponding measures. For example, when the warehouse inventory is close to the upper limit, the system will send an alarm to the manager so that the logistics plan can be adjusted in time, or it can monitor whether there are goods stranded in the warehouse for a long time, so that the manager can regularly clean up the stranded goods to avoid wasting storage space.

[0065] Step S300: receiving a browsing instruction input by a user, and visually displaying the park model based on the browsing instruction;

[0066] After running, it will automatically enter the non-roaming mode, and you can view the virtual scene model of the entire park system. You can view scene elements from multiple angles through mouse interaction. A first-person perspective roaming system is added to the scene and you can switch out of roaming. In roaming mode, users can experience the entire park in an immersive way. Add pop-up boxes to display information on security, fire protection, vehicles and other facilities and equipment in the scene. You can zoom in, zoom out, rotate, move and other basic operations on the scene through the mouse.

[0067] Step S400: comparing the on-site data with a preset threshold, and when the on-site data reaches the preset threshold, reading and displaying a corresponding pop-up panel;

[0068] Among them, the acquisition equipment includes a thermal imager, an optical sensor and a monitoring cloud platform, and the field data includes temperature, humidity, gas information and light information.

[0069] Through event monitoring, the required pop-up panel information is hidden in each module. The data required by the UI panel needs to be obtained from the relevant interface request. A communication mechanism between UIs is established to avoid the problem of low efficiency of back and forth calls.

[0070] The steps of acquiring the building data of the logistics park, performing three-dimensional modeling on the logistics park, and obtaining the park model include:

[0071] Obtain building data of logistics parks;

[0072] Obtain the shell material of each inherent facility in the logistics park;

[0073] Create a three-dimensional model based on the building data, and simultaneously determine the virtual facilities that correspond to the fixed facilities one by one; the size ratio of the fixed facilities and the virtual facilities is determined by the scale of the three-dimensional model;

[0074] The virtual facilities are inserted into the three-dimensional model, and the virtual facilities are rendered based on the shell material to obtain a park model.

[0075] The above content specifically describes the process of generating the park model. By acquiring the architectural data of the logistics park, a three-dimensional model can be generated. Then, virtual facilities corresponding to the inherent facilities are inserted into the three-dimensional model according to the shell material to obtain the park model.

[0076] Furthermore, the step of acquiring the on-site data of the logistics park based on the acquisition device, converting the on-site data into rendering values, and inserting the data into the park model includes:

[0077] Acquire on-site data with time tags in the logistics park based on collection equipment;

[0078] Input the field data in the same time tag into the preset conversion model to obtain the rendering value;

[0079] Copy the campus model, mark the point corresponding to the acquisition device in the campus model, and insert the rendering value of the same time tag into the point;

[0080] Insert time stamps of rendered values ​​into the campus model.

[0081] Field data refers to data collected by acquisition equipment, which includes thermal imagers, optical sensors and monitoring cloud platforms. Field data includes temperature, humidity, gas information and light information. These data are converted into displayable color values, which are called rendering values. The rendering values ​​at the same time are inserted into the same park model to obtain the park model at that time.

[0082] Furthermore, the step of receiving a browsing instruction input by a user and visually displaying the park model based on the browsing instruction includes:

[0083] Receive browsing instructions input by the user and adjust the display frame; the browsing instructions include zooming in, zooming out, rotating and moving;

[0084] Based on the display frame, the area in the park model is intercepted and visualized.

[0085] The display process is not complicated. The user determines a display frame with size and position, captures the corresponding area in the park model and displays it.

[0086] Furthermore, the step of comparing the field data with a preset threshold value, and when the field data reaches the preset threshold value, reading and displaying a corresponding pop-up panel includes:

[0087] Query the preset threshold value according to the type of field data;

[0088] Compare the field data with the threshold, and when the field data reaches a preset threshold, query the pop-up panel according to the threshold; the corresponding relationship between the threshold and the pop-up panel is preset;

[0089] Display the found pop-up panel.

[0090] The above content provides a pop-up window function. There are many types of field data. It is determined whether each type of field data has reached a threshold. If reached, the corresponding pop-up panel is read and displayed to realize the reminder function.

[0091] As a preferred embodiment of the technical solution of the present invention, the actual application process of the technical solution of the present invention mainly includes the following contents:

[0092] 1). Project preparation:

[0093] Before the project starts, it is necessary to confirm the concept and goal of the application system, formulate a development plan, determine the personnel composition of the development team, etc. It is also necessary to conduct customer demand research to understand the basic situation of the target audience and provide reference for the design and development of the application.

[0094] 2). Product requirements review:

[0095] The product team analyzes and extracts key information based on the existing relevant information of the application system, and organizes and outputs the requirements document. Based on the requirements document, the product is refined and the interactive prototype document is output. The art and development teams are organized to conduct a project requirements review meeting. The specific development cycle and project personnel work allocation are determined through the meeting. The project leader enters the product requirements into ZenTao by function, assigns them to the heads of each functional module, and then the heads of each module assign them to specific heads according to their functions.

[0096] 3). Art production:

[0097] Art production is one of the important links in application development. At this stage, artists will produce art resources according to the requirements of product application design, including UI, models, textures, special effects, etc. Unity supports importing art resources such as pictures, 3D models, textures, animations, etc. This solution can divide art into two parts for design and production.

[0098] a.UX design:

[0099] The UI art designer designs the interactive interface of the entire application system based on the product interactive prototype. After the design is completed, the project leader is notified to organize a UI review meeting, at which relevant project team members can propose modification suggestions for the UI. Finally, the modification plan is summarized and the UI designer improves and optimizes it based on the modified document. Cut the image according to the set resolution and format, upload the image to Blue Lake and synchronize it with the developer. The developer downloads the image and imports it into Unity, and modifies the import settings. According to the renderings and images provided by the artist, the relevant UI interface is built and restored on the Unity side.

[0100] b.3D Modeling:

[0101] 3D modelers model 3D models and application scenarios based on data collected on site and existing materials. Determine rendering pipeline with Unity. Model and render the entire logistics park at 1:1 scale using 3D modeling engine. Inform relevant personnel to review and export optimized models as .FBX format scene models and building model files, with textures, materials, and animations. Import the exported .fbx files into Unity and modify the import format as needed. Unity developers use editor tools to adjust and optimize art resources.

[0102] 4). Application system design:

[0103] a. Scene construction:

[0104] After importing the scene model file into Unity, check whether the texture is complete. If there is any problem, communicate with the modeler and modify the scene model file as needed. Save the modified scene model file as a prefab for subsequent use.

[0105] b. Interface construction:

[0106] Refer to the renderings provided by the UI and use the cutouts provided by the artist to build the 2D interface of the entire system. The restoration degree must reach more than 95%. Save each built interface panel as a prefab for subsequent development logic use, and communicate with the art designer when necessary.

[0107] c. Special effects production:

[0108] After completing the scene production and interface construction, we will find that there is a lack of dynamic elements, the overall appearance is very static, and the visual effect of the art design cannot be achieved. It is necessary to use particle effects and shaders to create certain special effects. Add them to the scene to make the scene visually polymorphic and rich. Save the prepared special effect files separately as prefabs to make subsequent modifications more convenient.

[0109] d. Animation production:

[0110] Through the resources provided by the artist, add the application running import transition animation. The UI is managed through 2D animation. Usually the dotween plug-in is used to design the animation effects of the 2D interface. Such as gradient display and hiding, etc. The virtual camera switching is slowly switched by interpolation motion.

[0111] 5). Programming interaction implementation:

[0112] In Unity, you can use programming languages ​​such as C# and LUA to write application logic and functions. Developers can use the API provided by Unity to implement various functions in the application, such as character control, collision detection, animation effects, etc. In addition, Unity also supports the use of plug-ins. Developers can choose appropriate plug-ins to expand the functions of the application as needed. This solution can be divided into three interactive modules.

[0113] a.Scene module:

[0114] After running, it will automatically enter the non-roaming mode, and you can view the virtual scene model of the entire park system. You can view scene elements from multiple angles through mouse interaction. A first-person perspective roaming system is added to the scene and you can switch out of roaming. In roaming mode, users can experience the entire park in an immersive way. Add pop-up boxes to display information on security, fire protection, vehicles and other facilities and equipment in the scene. You can zoom in, zoom out, rotate, move and other basic operations on the scene through the mouse.

[0115] bUI module:

[0116] Through event monitoring, the required pop-up panel information is hidden in each module. The data required by the UI panel needs to be obtained from the relevant interface request. A communication mechanism between UIs is established to avoid the problem of low efficiency of back and forth calls.

[0117] c. Network interface module:

[0118] When making an interface request in Unity, async and await can be used to make asynchronous requests to the interface. All information about tobacco storage is obtained through the interface and presented on the relevant information display panel. Users can intuitively view the entire storage system in real time. The data is mainly divided into ordinary interface data, which can be obtained through Http requests. In addition, some sensor data needs to be pushed to the Unity end by subscribing to websockets. In Unity, timely response data presentation and model presentation are achieved to achieve a trinity design of data synchronization, data distribution, and data presentation. The timeliness of storage data is the core part of the system, and delays, delays, and no data should be avoided as much as possible.

[0119] 6) Testing and Optimization:

[0120] In the application development project, testing and optimization are important links that cannot be ignored. At this stage, the tester will conduct comprehensive functional and performance tests on the application, submit relevant issues to ZenTao and assign them to specific persons in charge, who will verify and close the issue ticket after modification. This ensures the stability and smoothness of the application. At the same time, developers also need to optimize the application performance to improve the running frame rate and loading speed of the application. Unity provides a series of tools and functions, such as profiler and frame debugger, to help developers test and optimize applications.

[0121] 7). Deployment and launch:

[0122] After the application is developed, it can be deployed and released online. In Unity, you can choose to publish the application to different platforms, such as PC, mobile, Web and other platforms. This solution requires publishing packages for the WebGL platform and the PC platform. Switch to the corresponding platform for packaging, and after packaging, send the application package to the project leader, who will communicate and deploy it online.
