Fig. 1 shows a schematic diagram of an apparatus 100 for building a digital twin.

As shown in FIG. 1 , the device 100 includes an information mapping unit 110 , an interaction unit 120 and a control unit 130 for user selection.

The information mapping unit 110 is used to obtain the basic data and operating data of the physical entity, build a digital twin based on the basic data, and provide the operating data to the control unit.

The interaction unit 120 is used to obtain operating data from the physical entity and provide the operating data to the information mapping unit, and provide control strategies to the physical entity.

The control unit 130 is used to generate a control strategy according to the operation data provided by the information mapping unit, so as to control the digital twin and the physical entity.

In some embodiments of the present disclosure, each of the information mapping unit 110 , the interaction unit 120 and the control unit 130 may include at least one callable object, and the user may choose whether to use the callable object. For example, a user may invoke a callable object by selecting an image element of the callable object.

In some embodiments of the present disclosure, for example, the information mapping unit 110 interacts with the interaction unit 120 to obtain basic data and operating data of the physical entity. The basic data may include, for example, some appearance information such as the shape and size of the physical entity, and a structural model. Operational data can include, for example, the state of physical entities during operation or historical operational data such as physical index parameters, providing data support for building digital twins. For example, if the physical entity is an aircraft, the operating data may include the flight trajectory of the aircraft, the flight speed of the aircraft, and the like. For another example, if the physical entity is a server, the running data may include the temperature of the server, the running speed of the server, and the like.

Fig. 2 shows a schematic block diagram of the information mapping unit 110 provided by at least one embodiment of the present disclosure.

As shown in FIG. 2 , for example, the information mapping unit 110 includes a storage object 111 configured to store and manage basic data and operating data.

In some embodiments of the present disclosure, for example, a DTRecord object is defined to represent a storage object 111 capable of storing and managing basic data and running data. For example, a user can call a DTRecord object and instantiate it if necessary to store and manage basic and operational data. For example, the device 100 provides a DTRecord image element corresponding to the DTRecord object, and the user selects the DTRecord image element and places the DTRecord image element on the page for building a digital twin, and calls the DTRecord object to store and manage the operation of the digital twin. data. For example, after calling the DTRecord object, the user can instantiate the DTRecord object, and set parameters such as storage space and storage mode of the DTRecord object through instantiation.

As shown in FIG. 2 , the information mapping unit 110 may also include a visualization object 112 in addition to the storage object 111 . The visualization object 112 is configured to generate a visual mirror image of the physical entity as a digital twin based on the underlying data.

Because the digital twins and physical entities have a high degree of consistency in visual presentation. The visualization object 112, as an image rendering entity, is responsible for realizing the visual mirror image of the physical entity in the information world.

In some embodiments of the present disclosure, for example, a DTVisualizer object is defined to represent a visualization object 112 capable of generating a visual mirror image of a physical entity. For example, a user can call a DTVisualizer object, and instantiate it if desired, to generate a visual mirror image of a physical entity based on the underlying data. For example, the device 100 provides the DTVisualizer image element corresponding to the DTVisualizer object, and the user selects the DTVisualizer image element and places the DTVisualizer image element on the page for building a digital twin, and realizes calling the DTVisualizer object to generate a visual image of a physical entity based on the basic data. mirror image. For example, after calling the DTVisualizer object, the user can instantiate the DTVisualizer object, and set the visual parameters of the DTVisualizer object through instantiation. As shown in FIG. 2 , besides the storage object 111 and the visualization object 112 , the information mapping unit 110 may also include an animation simulation object 113 configured to render the digital twin so that the digital twin performs an action.

The animation simulation object 113 is used to reproduce the behavior and state of the physical entity, and is responsible for rendering and presenting the execution actions of the physical entity in the information world, so that the synchronization between the data twin and the physical entity can be maximized.

For example, the digital twin is the twin of the aircraft, and the execution actions can be actions such as U-turn, steering, and acceleration performed by the aircraft. The performed actions represented by the digital twin are consistent with those performed by the physical entity (e.g., an aircraft).

In some embodiments of the present disclosure, the interaction unit 120 may, for example, interact with sensors in the logistics entity to obtain operating data from the sensors.

In addition to obtaining operating data from the physical entity, the interaction unit 120 may also provide a control strategy to the physical entity, thereby optimizing the operation of the physical entity. The control strategy may be provided by the control unit 130 to the interaction unit 120 .

For example, for an aircraft, the control strategy may be the adjustment of the flight trajectory, the adjustment of the speed, and the like.

Fig. 3 shows a schematic block diagram of the interaction unit 120 provided by at least one embodiment of the present disclosure.

As shown in FIG. 3 , the interaction unit 120 includes a perception object 121 and an execution object 122 .

The sensing object 121 is bound to the physical sensors in the physical entity to obtain operating data from the physical sensors.

The execution object 122 is configured to convert the control policy into a control instruction for the physical entity, and provide the control instruction to the execution part of the physical entity, so that the execution part performs an action.

For example, the perception object 121 as a virtual sensor corresponds to a physical sensor in a physical entity, and serves as an entrance for the digital twin to obtain real-time operating data of the physical entity.

In some embodiments of the present disclosure, for example, a DTsensor object is defined to represent a perception object 121 capable of acquiring operating data from a physical sensor. For example, a user can call a DTsensor object to obtain operational data from a physical sensor. For example, the device 100 provides a DTsensor image element corresponding to the DTsensor object, and the user selects the DTsensor image element and places the DTsensor image element on the page for building a digital twin, so as to call the DTsensor to obtain operating data from the physical sensor.

For example, the execution object 122, as a virtual actuator, converts the control strategy into a control command that can be used by the physical entity, and transmits it to the corresponding execution component in the physical entity, so as to complete the feedback control of the digital twin to the physical entity.

In the embodiment of the present disclosure, the execution object 122 can interact with the physical entity through an interface conforming to the interaction protocol, so that the execution object converts the control policy into a control instruction, so that the physical entity can perform corresponding actions according to the control instruction.

In some embodiments of the present disclosure, for example, defining a DTActuator object means having an execution object 122 that converts a control strategy into a control instruction. For example, the user can call the DTActuator object to convert the control strategy into a control instruction. For example, the device 100 provides a DTActuator image element corresponding to the DTActuator object, and the user selects the DTActuator image element and places the DTActuator image element on the page for building a digital twin, and calls the DTActuator to convert the control strategy into a control instruction.

In some embodiments of the present disclosure, the control unit 130, for example, encapsulates relevant intelligent algorithms, calculates a control strategy using the operating data provided by the information mapping unit, and controls the digital twin and the physical entity according to the control strategy.

For example, a DTController object is defined to represent a control unit 130 equipped with an intelligent algorithm. For example, the device 100 provides a DTController image element corresponding to the control unit 130, the user selects the DTController image element and places the DTController image element on the page for building a digital twin, and realizes calling the DTController object to use the DTController object to calculate the control strategy.

In the above embodiments, dynamic interaction and closed-loop control are realized through processes such as perception, control, and execution.

As shown in FIG. 1 , in addition to the information mapping unit 110 , the interaction unit 120 and the control unit 130 , the device 100 may also include a physical stimulus simulation unit 140 for the user to choose. The physical stimulus simulation unit 140 is used to simulate the physical process of the physical entity.

By simulating the physical process of the physical entity through the physical excitation simulation unit, the consistency between the digital twin and the physical entity is further improved.

Fig. 4 shows a schematic block diagram of a physical excitation simulation unit 140 provided by at least one embodiment of the present disclosure.

As shown in FIG. 4 , the physical stimulus simulation unit 140 may include a condition declaration object 141 . Condition statement objects are used to provide information about the environment in which the physical process is located.

The occurrence of any physical process is based on specific prerequisites. Even the same physical process exhibits different characteristic laws under different realistic conditions. Therefore, when simulating the mechanism of physical processes, it is necessary to clarify the occurrence conditions. For example, a DTCondition object is defined as the condition declaration object 141 . For example, the user selects the DTCondition image element and places the DTCondition image element on the page of building a digital twin, and calls the DTCondition object to use the DTCondition object to simulate the environment information of the physical process.

The environmental information includes, for example, the ambient temperature, humidity, wind speed, and wind direction of the physical entity.

As shown in FIG. 4 , besides the condition statement object 141 , the physical stimulus simulation unit 140 may also include an evolution object 142 . The evolution object 142 is used to dynamically fit the physical process of the physical entity.

The physical characteristics of physical entities will change over time, so the simulation of physical mechanisms in digital twins should also keep pace with the evolution of physical entities. For example, the DTEvoler object is defined to represent the evolution object 142 with this evolution property, indicating the dynamic fitting of the data twin to the physical mechanism of the physical entity. For example, the user selects the DTEvoler image element and places the DTEvoler image element on the page of building a digital twin to realize the physical process of calling the DTEvoler object to dynamically fit the physical entity using the DTEvoler object.

It should be noted that each of the information mapping unit 110, the interaction unit 120, and the control unit 130 may include not only the objects mentioned above, but also more or fewer objects, and the objects included in each unit may be determined by this Design by those skilled in the art according to actual needs. Objects contained in each unit in the embodiments of the present disclosure may be expanded or changed by those skilled in the art.

The objects mentioned above can also be instantiated similarly to the DTRecord object and the DTVisualizer object, and the parameters of each object can be set through instantiation, which will not be repeated here.

Fig. 5 shows a schematic diagram of a digital twin architecture 500 provided by at least one embodiment of the present disclosure. The device 100 described above in FIGS. 1 to 4 is proposed based on the digital twin architecture 500 shown in FIG. 5 .

As shown in FIG. 5 , the digital twin architecture 500 includes two parts: a twin world 501 and a physical world 502 .

The twin world 501 includes an information mapping unit 510 , an interaction unit 520 , a control unit 503 and a physical stimulus simulation unit 540 . Physical world 502 includes physical entities 5012 .

Twin world 501 and physical world 502 interact through interaction unit 520 . For example, the interaction unit 520 may include a sensing object 521 configured to connect with a sensor of a physical entity, and obtain interaction information from the sensor of the physical entity in accordance with a communication protocol between the two. The interaction information may include, for example, real-time operation data such as actions and physical evolution of physical entities.

The storage object 511 in the information mapping unit 510 is configured to store and manage the real-time operation data from the perception object 521 and the basic data of the physical entity. The storage object 511 also interacts with the physical evolution simulation unit 540, and stores the simulation data obtained by the physical evolution simulation unit 540, and the like.

The condition declaration object 541 in the physical evolution simulation unit 540 monitors the condition change of the physical entity in real time, for example. When the condition of the physical entity changes, the condition declaration object 541 provides the evolution object 542 with the environment information of the physical process, so that the evolution object dynamically fits the physical process of the physical entity.

The visualization object 512 in the information mapping unit 510 renders the mirror digital twin of the physical entity according to the basic data in the storage object 511, and visualizes the appearance and structure model of the physical entity.

The animation simulation object 513 in the information mapping unit 510 simulates the actions and changes of physical entities, for example, according to the real-time running data in the storage object 511 .

The storage object 511 provides the control unit 530 with simulation data, real-time operation data, and historical operation data, etc., and the control unit 530 uses the intelligent algorithm in the control unit 530 to perform behavior simulation based on these data, so as to obtain an optimal control strategy.

The control unit 530 provides the optimal control strategy to the execution object 522 in the interaction unit 530 . According to the communication protocol with the physical entity 5021, the execution object 522 converts the optimal control strategy into a control instruction that the physical entity 5021 can recognize, and then sends the control instruction to the execution component of the physical entity 5021, so that the execution component performs an action.

The digital twin architecture shown in FIG. 5 is a new architecture proposed by the inventors of the present disclosure, and the device 100 is designed in the present disclosure based on this architecture. The device 100 may include a plurality of graphic entities, each graphic entity corresponds to an object, and is called by a user to construct a digital twin.

In at least one embodiment of the present disclosure, based on the definition of each object of the digital twin, the construction of the digital twin can be carried out. In order to make the modeling process more efficient and the model more intuitive, it is also necessary to image elements of the object (referred to as "image Element") for a good graphical design to get primitives in graphical modeling tools.

Expressing data twin elements with simple and intuitive primitives can allow modelers to improve modeling efficiency during use and reduce the cost of learning and preparation in the early stage of modeling. Due to the characteristics of graphics being intuitive, concise, and rich in meaning, with clear signs, clear rules, and reasonable organizational structure, the graphics form a model file, so that users and sharers who use the model can efficiently obtain model information, and realize physics through the model. object purpose.

In at least one embodiment of the present disclosure, the graphic element may include an icon sub-element and a shape sub-element, the icon sub-element is located in the shape sub-element, and the icon sub-element indicates the function of the object in a diagrammatic manner. For example, the shape child element can be a rectangular box, an oval box, etc. The icon sub-element may be a picture designed according to the object.

For example, two image elements belonging to the same cell have the same color or the same shape subelement. The color or shape sub-elements of two image elements belonging to different elements are different. For example, the DTAnimation primitive, the DTVisualizer primitive and the DTRecord primitive above all belong to the primitives of the information mapping unit 110, so the DTAnimation primitive, the DTVisualizer primitive and the DTRecord primitive have the same color or the same shape sub-elements. For example, DTAnimation primitives, DTVisualizer primitives, and DTRecord primitives are all filled with yellow.

The DTAnimation primitive and the DTCondition primitive are respectively the primitives of the information mapping unit 110 and the physical evolution simulation, so the DTAnimation primitive and the DTCondition primitive are filled with yellow and purple respectively.

Similar shapes or similar colors should be used for the same type of primitives. Modelers and model users can use this external obvious feature to judge highly correlated model elements, which facilitates the unified organization and management of the same type of model elements. .

In at least one embodiment of the present disclosure, the image element is configured to display detailed information of the object represented by the image element in response to a trigger operation.

For example, the triggering operation is a click operation, a double-click operation, and the like.

The area occupied by primitives in the model canvas is limited, so it is necessary to filter the most concerned and representative information of each primitive to be displayed in the canvas, and other detailed information of primitives can be opened by triggering operations such as clicking. view, thus rendered in the detail view. The detailed view is displayed in the form of a hover popup, for example.

In some embodiments of the present disclosure, the icon sub-element in the graphic element is another type of visual element representing the information of the modeling element represented by the graphic element besides the shape and color. Since the icon has simulacrum, it can help Modelers and model users can more accurately and quickly understand the model elements represented by primitives, and the icons have a high degree of association.

In some embodiments of the present disclosure, the data twin model often involves multiple dimensions and multiple physical fields, and the number and types of model elements are more diverse and complex than those of general domain models. If visual elements (shape, color, icon, etc.) are used without restriction to distinguish different primitives, the focus of model information will be disturbed due to too many visual elements. Therefore, when designing primitives, it is necessary to ensure that the visual elements used by primitives presented in the same canvas are as simple as possible.

In some embodiments of the present disclosure, the image element further includes an object name of the object represented by the image element. For example, the name of the DTAnimation primitive is Animation Simulation Object. The object name may, for example, be located outside the shape sub-element, eg near the bottom right corner of the shape sub-element.

In some embodiments of the present disclosure, the device 100 further includes a first connection graphic element, and the first connection graphic element is used to connect at least two first objects selected by the user to indicate that between the at least two first objects logical relationship.

Each of the at least two first objects is an object selected by the user for use from a plurality of objects provided by the device 100 . For example, the at least two first objects include a DTsensor object and a DTRecord object and so on.

A logical relationship may include, for example, a connection or influence between at least two first objects. For example, the real-time data sensed by the DTsensor object is stored by the DTRecord object, so the DTsensor object and the DTRecord object can be connected through the first connection primitive. For another example, the DTCondition object declares single-engine aging, which will cause the DTEvoler object to recalculate the flight curve, that is, the DTCondition object affects the DTEvoler object, so the DTCondition object and the DTEvoler object are connected through the first connection primitive.

In some embodiments of the present disclosure, the device 100 further includes a second connection graphic element, which is used to connect at least two second objects selected by the user to indicate the data between the at least two second objects transitive relationship.

The second connection primitive is different from the first connection primitive. For example, the first connection primitive is a dotted arrow, and the object pointed by the arrow is the object affected by the object at the other end of the dotted arrow; the second connection primitive is a solid arrow, and the object pointed by the arrow is the object receiving data, and the solid arrow The other end of is the object that sends the data.

For example, the DTController object sends the control policy to the DTActuator object, then the DTController object and the DTActuator can be connected through a second connection graphic element (for example, a solid arrow), and the solid arrow points from the DTController object to the DTActuator object.

The relationship between the various objects in the digital twin can be clearly indicated through the first connection primitive and the second connection primitive, making the digital twin concise and easy to understand.

FIG. 6 shows examples of various image elements provided by at least one embodiment of the present disclosure. It should be noted that the image elements shown in the table in FIG. 6 are only an example, and the embodiments of the present disclosure are not limited thereto.

For example, a graphic element of a DTsensor object includes an icon sub-element 601 and a rectangular box (ie, a shape sub-element) 602 , and displays the object name near the lower right corner of the rectangular box or displays the object name below the rectangular box.

In some embodiments of the present disclosure, the object name can be modified by the user, for example, the user can modify the object name to a name related to the digital twin on the construction page of the digital twin. For example, modify the DTCondition object to single engine failure.

For example, if you click on the primitive of the DTsensor object in the canvas, the function of the DTsensor object will be displayed in the pop-up window, that is, the meaning of the primitive is "access to the running information of the physical entity after binding with the physical sensor".

For example, in Figure 6, the shape sub-elements of the DTAnimation primitive, the DTVisualizer primitive and the DTRecord primitive are all filled with yellow, and each icon sub-element is also yellow. The shape sub-element of the DTCondition primitive is filled with purple, and the icon sub-element is also purple.
