Description

Digital twin implementation system and digital twin implementation method {Digital twin implementation system and digital twin implementation method}

The present invention relates to a digital twin implementation system and a digital twin implementation method. More specifically, the present invention relates to a digital twin agent based on the discrete event system formalism, which allows objects in physical space to be registered as digital objects in virtual space more easily and quickly. It relates to a possible digital twin implementation system and digital twin implementation method.

Recently, the term digital twin has been used in daily life and various industrial fields such as ports, transportation, buildings, energy, and shipbuilding. As digital twins are used in the process of building and operating smart cities, they are exposed to citizens in their daily lives and appear on subway and highway billboards to reach people.

The surface form of the digital twin turns a real object in the real world into a twin virtual object in the virtual world, and makes the movements and actions of the real object a performance role model for the twin virtual object, allowing the real world to be copied and simulated in the virtual world. It appears that

Digital twins have been partially used in the manufacturing field since the concept was first introduced in 2002, and there are likely several reasons why they have recently gained attention in many industries.

First, the basic technology has been accumulated to the point where the digital twin concept can be specified and applied even in new fields. You can create a 3D shape for the physical object for which you want to create a digital twin model, visualize it through augmented reality and virtual reality, and create a virtual model of the object's function and operation.

The point is that data can be collected while monitoring the actual operation status of the object in real time and analyzed through big data, artificial intelligence, etc. Through the digital twin system, which is created like a twin in each application field, it becomes possible to verify simulations in advance for planning, operation, management, maintenance and early response, perform optimization during system operation, predict future situations, and analyze problems after the fact. It is starting to be widely adopted.

The second reason is because of the intuitive name that anyone can quickly understand.

For an unfamiliar concept to survive and spread in the business ecosystem, a virtuous cycle of acceptance and investment must be created, and digital twin is a name that can be easily understood by anyone, including investors with a humanities background.

Because digital twins provide people with images of twins facing mirrors, what you want to deal with appears in cyberspace and can be manipulated as you like. Even if you cannot drive a car in the real world, it provides the experience of driving the same car in cyberspace. It can be understood that the familiar, close, and pretty sensuous names called twins all work together to attract people's attention.

However, in order to digitally twinize objects in physical space, the process is performed by highly skilled technicians, enabling even unskilled people to easily and simply implement digital twins of objects or systems in physical space in virtual space. The development of the system is urgently needed.

In addition, in the present application, terms such as "comprise" or "have" are intended to designate the presence of features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, but are not intended to indicate the presence of one or more other It should be understood that this does not exclude in advance the presence or addition of features, numbers, steps, operations, components, parts, or combinations thereof.

Figure 1 is a block diagram schematically showing the internal configuration of a digital twin implementation system according to an embodiment of the present invention.

Referring to the drawings, the digital twin implementation system 1000 according to an embodiment of the present invention largely includes a system structure DB 200 storing at least one modularized system structure based on the discrete event system formalism, and A system model DB 300 in which at least one system model, which is a software model for controlling the system structure, is stored, and the system structure DB 200 based on target information about the object in the received physical space. ) and a digital twin agent (100) that requests the system structure and system model corresponding to the object from the system model DB 300, and generates an executable digital object by synthesizing the system structure and system model received according to the request. ) includes.

Here, the digital twin agent 100 is equipped to convert a specific object in physical space into a digital object in virtual space and register it, as described above. This digital twin agent 100 digitally converts the object into a digital object. To twinize, this is done by selecting and synthesizing system structures and system models based on the discrete event system formalism.

For example, instead of using the system in physical space directly, the digital twin agent 100 uses a mathematical model to model the system so that various virtual simulations can be performed in virtual space, and various virtual experiments are performed through the modeling. It can be said to be a digital twin synthesis framework that allows.

Below, before explaining the digital twin agent 100 of the present invention, virtual simulation and simulation based on the discrete event system formalism for the same will be described.

As mentioned above, the reason for performing virtual simulation is to significantly save time, manpower, and cost by using a computer model instead of using a real system, and at the same time, in the case of systems that may be exposed to hazardous environments, various experiments can be conducted without physical or physical risk. This is because there is an advantage in being able to do so.

Because of these advantages, computer simulations are widely used in various fields such as engineering, science, and military science.

In virtual factory simulation, instead of actually constructing factories scattered in various locations, a computer model is used to predict the expected production volume under given human and material resources and utilize these resources optimally to maximize production. A method can be developed.

In the field of business reengineering, instead of actually reorganizing the company's organization, the process in which the organization and internal personnel move cooperatively is modeled on a computer and the results are evaluated through simulation to provide reliable management innovation without financial risk. A conclusion can be drawn.

These simulations can be classified into continuous time simulations that numerically analyze differential equation models and discrete time simulations that analyze finite state mechanical models. The digital twin implementation system (1000) according to the present invention In , the discrete time simulation model is executed at regular time intervals (time driven).

Simulation using this discrete event system model does not proceed with the simulation over time, but only executes the model when an event occurs outside or inside the system.

Additionally, in discrete event simulation, an event refers to an abstract signal that occurs outside or inside the system, and a discrete event refers to an event that occurs irregularly at a random time.

Therefore, discrete event simulation is more efficient than continuous-time or discrete-time simulation because no calculations are performed on the model at times when no event occurs, and can be used to design and analyze parallel/distributed computer systems, communication systems, production systems, and transportation systems. It can also be used in simulated electronic warfare and electronic entertainment games.

In addition, the method of modeling and simulating such a discrete event system is to use simulation languages/environments specially developed for discrete event simulation, such as GPSS, SIMSCRIPT, SLAM, SIMAN, etc., and the second method is to implement mathematical formalism in a general-purpose computer language. There is a way to use a simulation environment.

The advantage of the above simulation languages is that the system can be modeled relatively easily using the grammar and semantics provided by the language without relying on difficult mathematical formalism, but these languages must be learned anew and, furthermore, the semantic ambiguity of these languages ( The disadvantage is that confusion occurs during the modeling process due to ambiguity.

In addition, using a simulation environment that implements the mathematical formalism using a general-purpose computer language not only overcomes the disadvantages of using a simulation language, but also has various advantages.

In other words, the role of mathematical formalism in modeling is to provide a framework or semantics that formally describes the behavior of the system.

In this mathematical formalism, the operation of the system is expressed as a set of parameters and constraints between these sets. For example, in the DEVS (Discrete EVent System Specification) formalism, which is a representative mathematical formalism of discrete event systems, the discrete event system continues to be hierarchically decomposed into several sub-models, and then when these models can be easily and accurately described, Does not disassemble

At this time, the smallest unit model that can no longer be decomposed is called an atomic model, and models other than the atomic model are called coupled models.

The atomic model expresses and combines three parameter sets, that is, an input event set, an output event set, a state set, and the constraints between them, with four characteristic functions: external state variation function, internal state variation function, output function, and time forward function. A model specifies the connection relationships between multiple atomic (bond) models.

In this way, specifying the system model for each component that corresponds to an existing system and then specifying the entire system through their connection relationships is called object-oriented modeling.

A good simulation environment must be convenient for users at each stage of the simulation and efficient throughout the entire simulation process. The core technologies required to develop such a simulation environment should be divided into modeling, simulation engine, input/output analysis, real-time processing, and user interface.

Modeling tools should be able to develop models easily and quickly while avoiding the use of difficult mathematical equations or computer algorithms if the user fully understands the system they wish to simulate. In fact, many commercial simulation environments support user interfaces that develop models using pictorial shapes that resemble the actual appearance of the system. However, in order to shorten the overall simulation cycle, reuse and effective maintenance of simulation models are essential.

For this purpose, a hierarchical object oriented modeling technique that expresses objects in a modular hierarchical structure and specifies them as object-oriented is desirable.

Therefore, the digital twin agent 100 according to the present invention organizes objects in physical space into a system structure (SS; System Structure) and a system model (SM; System) in a modularized hierarchical structure based on the discrete event system formalism as described above. Model) is registered and synthesized to create an executable digital object.

Here, the system structure (SS) is the target information about the object in the physical space that the user wants to convert into an executable digital object, for example, the object's objective information, hardware specification information, and requirements information (Requirements) corresponding to the virtual object. It is structural information about a system in the form of individual hardware or a combined model in space, and the system model (SM) refers to a software model for controlling and managing such a system structure.

Therefore, when the digital twin agent 100 receives target information of an object for converting it into a digital object and registering it in a virtual space from the user, the system structure (SS) corresponding to the target information and a system model for controlling it ( SM) is received from the system structure DB 200 and the system model DB 300, they are synthesized, and registered as an executable digital object.

Here, an interface unit 110 is provided to receive target information from the user, and through this interface unit 110, in addition to receiving target information, a two-way interface with the user is performed in various forms.

Of course, the digital twin agent 100 may be configured to directly receive the user's input information for two-way interface with the user through the interface unit 110, but as shown in FIG. 1, the two-way interface is performed between the user and a remote location. A separate user terminal 400 may be provided to enable this.

In addition, if at least one of the system structure (SS) and system model (SM) corresponding to the target information is not in the system structure DB 200 and the system model DB 300, the digital twin agent 100 The system structure (SS) and system model (SM) corresponding to the target information are separately created and used to create a digital object, and the separately created system structure (SS) and system model (SM) are stored in the system structure DB (200). and can be stored in the system model DB (300).

Such system structure (SS) and system model (SM) are generated by the digital twin agent 100 by receiving system structure creation information and system model creation information through the interface unit 110. The information includes name information, interface information, hardware specification information, and requirements information of the system structure to be created, and examples of the system model creation information include simx, binary, lib, dll, .a, and .so. A software model, etc. may be applied.

Meanwhile, even when the digital twin agent 100 receives the system structure (SS) corresponding to the target information from the system structure DB 200, if system structure supplementation information is received from the user through the interface unit 110, The system structure (SS) can be modified based on the system structure supplementary information.

Here, in order to determine that the system structure (SS) received by the digital twin agent 100 requires supplementation, two types of judgment criteria can be set. First, as described above, the received system structure (SS) The digital twin agent 100 can be configured to determine that supplementation is necessary depending on whether the user requests supplementation or system structure supplementation information is received through the interface unit 110, and secondly, the received target information and A separate judgment standard may be set in advance for the degree of discrepancy between the system structures (SS) received as corresponding ones, and it may be determined that supplementation is necessary based on that judgment standard.

Of course, after modification, the modified system structure (SS) can be registered as an executable digital object based on the modified system structure (SS) and at the same time, the modified system structure (SS) can be stored in the system structure DB 200.

According to an embodiment of the present invention, executable digital objects are divided into sensors, processors, and actuators, and each module can be synthesized, and the system structure (SS) and system are integrated in an integrated form. It may be stored on the model (SM).

In addition, the digital twin agent 100 can create an executable digital object, process it in the sensor signal and processor generated in the process of performing simulation, and transmit it to the actuator. The actuator identifies and analyzes signals received periodically and Able to perform specified movements.

Figures 2 and 3 are diagrams showing a system structure creation process for creating an executable digital object according to an embodiment of the present invention.

Referring to the drawing, as shown in FIG. 2, the executable digital object is a disaster notification system, and the hierarchical structure that constitutes it is first classified into a fire notification system and an earthquake notification system.

These fire notification systems and earthquake notification systems are currently stored in the system structure DB 200, and these system structures are essential system structures (ESS) that must be connected to form the system structure of the upper layer. Wow, it can be classified as a selective system structure (SSS) that can be selectively connected.

In Figure 2, the essential system structure (ESS) may include Sensor HW, Network HW, Processor, and guidance service, and the optional system structure (SSS) may include a fire notification system, earthquake notification system, and fire alarm.

This essential system structure (ESS) is selected together when the system structure of the upper layer is selected, and the selection of the selection system structure (SSS) is determined based on user selection information through the interface unit 110.

In Figure 2, the essential system structure (ESS) is indicated by And, and the optional system structure (SSS) is indicated by OR.

Of course, the system model (SM) for the corresponding system structure (SS) is not illustrated in FIG. 2, but examples of the system model (SM) are shown in FIGS. 5 and 6, which will be described later.

In addition, in the case of the autonomous driving kit of FIG. 3, a selection system structure (SSS) such as a basic kit and an advanced kit can be provided to the user through the interface unit 110, and when the user's selection information selects the basic kit, the sensor Essential system structures (ESS) such as HW, Network HW, Motor, Camera, and Wheels are specified and connected.

Additionally, as shown in Figure 3, the user can select between Bluetooth or WIFI as the system structure (SS) that constitutes the Network HW.

In this way, when a digital object is created in the digital twin implementation system according to the present invention, the digital twin agent 100 creates the corresponding system structure (SS) based on target information about the object in physical space into the system structure DB 200. After selecting the system structure (SS), the system model (SM) corresponding to the selected system structure (SS) is requested from the system model DB 300 so that the user can easily select the system model as well. Provided so that you can

Once the selection of the system structure (SS) and system model (SM) is completed, the digital twin agent 100 synthesizes them, and through this, registration of executable digital objects in the virtual space is completed.

As such, the digital object according to the present invention can be synthesized by combining various types of modularized system structures and system models based on the discrete event system formalism by the digital twin agent 100, resulting in various resulting forms of the desired simulation. You can obtain result information according to .

Figure 4 is a flow chart showing the digital object creation process according to an embodiment of the present invention.

Referring to the drawing, in the digital object creation process according to this embodiment, the digital twin agent 100 first receives target information on the object in the physical space that is to be created as a digital object (S10), identifies it (S11), and The corresponding system structure (SS) is requested from the system structure DB 200 (S12).

If a corresponding system structure (SS) exists, the digital twin agent 100 requests the system model DB 300 to check whether there is a corresponding system model (S20).

If there is no corresponding system structure (SS), confirmation is requested whether a system structure similar to the corresponding system structure exists (S14), and if so, the corresponding system structure is received and provided to the user through the interface unit 110, and the system structure is received from the user. When structural supplementation information is received, the system structure is supplemented (S15).

Additionally, if there is no similar system structure (SS), the user is notified of this through the interface unit 110, and when system structure creation information is received from the user, the system structure is created based on this (S15).

Accordingly, the supplemented or created system structure (SS) is registered (selected) as a system structure in the digital twin agent and stored in the system structure DB 200 (S17).

Meanwhile, when system structure registration (selection) is completed, the system proceeds to step S20 described above and requests the system model DB 300 to check whether there is a system model (SM) corresponding to the system structure (SS) (S20).

If there is a system model, select the system model (S21). If not, notify the user and request system model creation information. When the system model creation information is received, create a system model (SM) (S22) and register it. It becomes (S23).

Accordingly, it is checked whether the selection of the system model has been completed (S24), and if it is determined to be complete, the corresponding system structure and system model are synthesized (S25), and the creation of an executable digital object is completed (S26).

Figures 5 and 6 are diagrams exemplarily showing the hierarchical structure in the digital object creation process according to the present invention.

Referring to the drawings, selection of the system structure (SS) and system model (SM) is performed as shown in Figures 5 and 6 to create executable digital objects in the digital twin implementation system 1000 according to the present invention. As described above, the system structure (SS) and system model (SM) are composed of the required system structure (ESS), the selected system structure (SSS), the required system model (ESM), and the selected system model (SSM).

Figure 5 shows the hierarchical structure of the digital object to be created, and Figure 6 shows the digital twin implementation system 1000 that performs the process of providing, selecting, and creating a system structure and system model with this hierarchical structure.

As described above, the provision of such a system structure (SS) and system model (SM) is provided when the digital twin agent 100 receives target information from the user terminal 400 and creates a system structure DB 200 and a system model based on this. The system structure (SS) and system model (SM) are requested and received from the DB (300) and provided to the user terminal (400).

If there is a selection system structure (SSS) or selection system model (SSM) in the system structure (SS) or system model (SM), the digital twin agent 100 receives selection information from the user terminal 400 and selects the system. You will choose either a structural (SS) or a systemic model (SM).

In addition, if there is no system structure (SS) corresponding to the target information, this is notified to the user terminal 400, and when system structure supplementation information or system structure creation information is requested and received, the system structure is supplemented or created. .

A step of requesting a corresponding system structure (SS) (S200), a step of receiving a system structure (SS) corresponding to the object from the system structure DB (S300), and the system structure received in the system model DB ( A step of requesting a system model (SM) corresponding to SS (S400), a step of receiving the system model (SM) corresponding to the system structure from the system model DB (S500), and the received system structure (SS) ) and synthesizing the received system model (SM) and registering it as an executable digital object (S600).

In addition, in step S200, the digital twin agent 100 requests the system structure (SS) corresponding to the object to the system structure DB, and if the system structure exists in the system structure DB, it is received (S300).

If the digital twin agent 100 determines in step S300 that there is no corresponding system structure (SS) or that there is a similar system structure but needs to be supplemented, this is notified to the user through the interface unit 110, and the user receives system structure creation information or When system structure supplementation information is received, the system structure (SS) is created or supplemented based on it.

Of course, the generated system structure (SS) or the supplemented system structure (SS) can be used in the conversion process of the digital object to be registered, and at the same time, the corresponding system structure (SS) can be registered in the system structure DB 200.

Meanwhile, when the digital twin agent 100 receives, creates or supplements the system structure, it requests the system model DB 300 for a system model (SM) corresponding to the system structure (SS) (S400) , if there is a corresponding system model (SM), the system model is received from the system model DB 300 (S500).
