Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to a method for constructing a digital twin scenario of a low-carbon park, a computer device, a medium and a product. Background Art

[0002] The digital twin scenario is an extension of the information data of the physical world. It is a virtual model technology that builds a digital world corresponding to the physical world. Usually, the devices, device data, and analysis trends of device data managed on the AIoT (Artificial Intelligence Internet of Things) platform can be analyzed and displayed more intuitively through the digital twin scenario.

[0003] In the real world, there are objectively low-carbon parks in different business scenarios, such as low-carbon parks for industry, commerce or residential areas. The construction of digital twin scenarios corresponding to low-carbon parks needs to meet the needs of specific business scenarios and show different business effects for different business scenarios.

[0004] In this regard, the construction of common low-carbon park digital twin scenes requires modeling, importing the model into the development tool to build the scene, and calling the data interface to bind and display data. The above operations require technicians with certain professional knowledge to complete, and the development process is complicated; when the same model is used in different low-carbon park scenes, it is necessary to repeat the complicated work of importing and building; when the displayed data is modified, it may be necessary to rebuild it. This brings inconvenience to the construction of digital twin scenes in low-carbon parks. Summary of the invention

[0005] The first purpose of the present invention is to provide a method for constructing a digital twin scene of a low-carbon park that can be constructed without professional knowledge.

[0006] The second object of the present invention is to provide a computer device for implementing the above-mentioned digital twin scene construction method.

[0007] The third object of the present invention is to provide a computer-readable storage medium for implementing the above-mentioned digital twin scene construction method.

[0008] The fourth object of the present invention is to provide a computer program product that implements the above-mentioned digital twin scene construction method.

[0009] In order to achieve the above-mentioned first purpose, the present invention provides a digital twin scene construction method for a low-carbon park, which is applied to the browser side, and includes the following steps: obtaining a scene creation instruction, creating a scene instance, and the scene instance includes a canvas; obtaining descriptions of multiple digital components from an external model library and displaying the descriptions of the multiple digital components in a visual manner; obtaining description information of multiple object models from an external Internet of Things platform and displaying the description information of the multiple object models in a visual manner, and the description information of the object model includes the object model code; obtaining a drag instruction, and introducing the first digital component corresponding to the drag instruction into the canvas; obtaining a style configuration instruction, and setting the style of the second digital component corresponding to the style configuration instruction; the second digital component is one of the multiple first digital components; obtaining a first data binding instruction, and binding the object model code corresponding to the first data binding instruction to the third digital component corresponding to the first data binding instruction; the third digital component is one of the multiple first digital components; publishing the target digital twin scene according to the scene instance.

[0010] It can be seen from the above scheme that the present invention can directly operate the three-dimensional digital twin scenes of low-carbon parks in different business scenarios through the visual interface provided on the browser side based on the external Internet of Things platform and model library, dynamically drag the digital components to build the scene, dynamically configure the scene style, and dynamically configure the binding data for the digital components in the scene, thereby realizing the rapid and convenient construction of the three-dimensional digital twin scenes of the low-carbon park. For operators who do not have the background knowledge of modeling, the present invention can quickly build a complete low-carbon park scene on the visual interface through intuitive operations that conform to the average person, that is, selecting clicks, dragging and other operations, without considering professional operations such as interface calls. Since the digital twin scenes corresponding to different low-carbon parks are relatively similar, the present invention can reduce the complexity of the digital twin scenes of general low-carbon parks and reduce the repeated implementation of some common scenes.

[0011] A further solution is to obtain a second data binding instruction, bind the static data corresponding to the second data binding instruction to the fourth digital component corresponding to the second data binding instruction, the fourth digital component is one of the first components, and the fourth digital component is different from the third digital component.

[0012] It can be seen that the present invention can bind static data to the fourth digital component to meet diverse construction requirements.

[0013] A further solution is to obtain multiple digital components from an external model library, and display the multiple digital components in a visual way and by distinguishing different business scenario classifications.

[0014] This shows that it is convenient for operators to make choices based on different business scenarios, further reducing the knowledge requirements for operators.

[0015] A further solution is to set the style of the second digital component corresponding to the style configuration instruction, including setting the color, brightness or contrast.

[0016] It can be seen that the scene style can be modified at any time according to actual needs.

[0017] In order to achieve the above-mentioned second purpose, the present invention provides a computer device, including a processor and a memory, wherein: a computer program is stored in the memory, and when the computer program is executed by the processor, the above-mentioned method for constructing a digital twin scene of a low-carbon park is implemented.

[0027] The digital twin scene construction method of the low-carbon park of the present invention is based on digital mirroring, and quickly builds microservices of the digital twin scene of the low-carbon park on the Web application, realizes dynamic drag and drop construction, dynamic configuration of scenes, and configuration binding data in the visual configuration interface on the browser side, thereby realizing the rapid construction of the digital twin scene of the low-carbon park.

[0028] Example of a method for constructing a digital twin scenario for a low-carbon park:

[0029] See also Figure 1 The digital twin scene construction system for implementing this embodiment includes an Internet of Things platform 11, a browser end 12, and a cloud model platform 13. The Internet of Things platform 11 is connected to the browser end 12, and the browser end 12 is connected to the cloud model platform 13.

[0030] The Internet of Things platform 11 includes multiple object models, and one object model corresponds to a device in the real world. The description information of the object model is used to describe the characteristics of the object model, including the object model code, the object model name, etc. Among them, each object model code is unique, and the corresponding object model can be uniquely determined based on the object model code.

[0031] The cloud model platform 13 includes a model library, which includes multiple digital components and descriptions of the digital components. Digital components are the basic elements required to build a digital twin scene, and are the digital representation of the real world in the virtual space. Digital components include maps, white models, three-dimensional models, data tags, etc. The description of the digital component is used to represent the information of the digital component, including name, size, preview image, etc.

[0032] In this embodiment, the Internet of Things platform 11 and the cloud model platform 13 are a whole, integrated in the AIoT platform, and the AIoT platform is connected to the browser end 12 to realize data transmission. In other embodiments, the Internet of Things platform 11 and the cloud model platform 13 can also be separately set up.

[0033] This embodiment is specifically implemented by executing a computer program through the browser 12. The browser 12 obtains user input events (user input events are events triggered by a user's mouse click operation or keyboard input operation), obtains different instructions according to different user input events, and executes corresponding steps according to specific instructions to realize the rapid construction of the digital twin scene of the low-carbon park, which specifically includes the following steps:

[0034] S1: Get the scene creation instruction and create a scene instance.

[0035] Among them, the scene instance provides necessary support for building the digital twin scene of the low-carbon park, such as the resources required to render digital components and the canvas for visual display.

[0036] S2: Obtain descriptions of multiple digital components from an external model library and display the descriptions of the multiple digital components in a visual manner.

[0037] Among them, see Figure 3 , Figure 3 A description including a plurality of digital components is shown. Each digital component is classified according to a classification list of a catalog, for example, the classification list includes three-dimensional maps, buildings, plant landscapes, and the like.

[0038] In other embodiments, the descriptions of multiple digital components are also displayed according to different business scenarios, such as the descriptions of the digital components required to build a digital twin scene of a low-carbon park under business scenarios including industry, commerce, and residential areas.

[0039] S3: Obtain description information of multiple object models from an external IoT platform and display the description information of multiple object models in a visual manner.

[0040] Among them, see Figure 4 , Figure 4 The description information of multiple object models is shown, wherein the "device code" corresponds to the object model code of this embodiment, and the "device name" corresponds to the object model name of this embodiment.

[0041] S4: Obtain a drag instruction, and introduce a first digital component corresponding to the drag instruction into the canvas.

[0042] When a first digital component is introduced into the canvas, the user operates the mouse on Figure 3 In the interface shown, drag one of the preview images of the description of the specified multiple digital components to the canvas, and the dragging operation generates a drag command as a user input event, so that the corresponding first digital component is introduced from the external model library to the canvas according to the drag command. Then continue the operation to introduce the next required first digital component to the canvas.

[0043] S5: Obtain a style configuration instruction, and set a style for the second digital component corresponding to the style configuration instruction.

[0044] The second digital component is one of the first digital components, and the style settings include viewing angle, color, brightness, contrast, etc. The style settings of the digital twin scene are realized through the style configuration instructions. Figure 5 , Figure 5The interface of the canvas is shown, and the setting can be made directly by clicking the corresponding digital elements on the canvas.

[0045] S6: Obtain a first data binding instruction, and bind the object model code corresponding to the first data binding instruction to the third digital component corresponding to the first data binding instruction.

[0046] S7: Obtain a second data binding instruction, and bind the static data corresponding to the second data binding instruction to the fourth digital component corresponding to the second data binding instruction.

[0047] Among them, the third digital component is one of the above-mentioned first digital components. The first data binding instruction is used to bind the third digital component to a physical model code, so that when the physical model corresponding to the physical model code is updated, the third digital component in the digital twin scene is updated synchronously, and the physical model is updated when the corresponding device status is updated, so that the device data changes in the real world are synchronized to the corresponding third digital component. The second data binding instruction is used to bind the fourth digital component to static data, that is, the fourth digital component is unchanged in the digital twin scene. The third digital component is different from the fourth component.

[0048] S8: Publish the target digital twin scenario based on the scenario instance.

[0049] See also Figure 6 , Figure 6 The generated target digital twin scenario is shown.

[0050] In other embodiments, operations of adding, deleting or modifying the model library may be performed by obtaining upload management instructions from the user.

[0051] In summary, the present invention can directly operate the three-dimensional digital twin scenes of low-carbon parks in different business scenarios through the visual interface provided on the browser side based on the external Internet of Things platform and model library, dynamically drag digital components to build scenes, dynamically configure scene styles, and dynamically configure binding data for digital components in the scene, thereby realizing the rapid and convenient construction of three-dimensional digital twin scenes of low-carbon parks. For operators who do not have background knowledge in modeling, the present invention can quickly build a complete low-carbon park scene on the visual interface through intuitive operations that are consistent with ordinary people, that is, selecting clicks, dragging and other operations, without considering professional and operations such as interface calls. Since the digital twin scenes corresponding to different low-carbon parks are relatively similar, the present invention can reduce the complexity of digital twin scenes of general low-carbon parks and reduce the repeated implementation of some common scenes.
