[0025] The power system refers to a group of equipment and components used to generate, transmit and control power, including engines, power transmission systems, hydraulic systems, etc. The power system can be a ship power system, which includes subsystems such as condensate feed water system, cooling water system, and lubricating oil system. A test bench is a device or platform used to test the power system, usually used to simulate real working conditions to evaluate the performance, reliability and safety of the system. The test bench test can collect various power system test data.

[0026] Digital twins make full use of physical models, sensor updates, operation history and other data, integrate multi-disciplinary, multi-physical quantity, multi-scale, and multi-probability simulation processes, complete mapping in virtual space, and thus reflect the entire life cycle of the corresponding physical equipment. Digital twins are a concept that transcends reality and can be regarded as a digital mapping system of one or more important and interdependent equipment systems. Digital twins are a universally adaptable theoretical and technical system that can be applied in many fields. They are widely used in product design, product manufacturing, medical analysis, engineering construction and other fields. The most in-depth application in China is in the field of engineering construction, and the field of intelligent manufacturing has received the highest attention and the hottest research.

[0027] In the related art, digital twins can be used in the process of bench testing of ship power systems to simulate the bench operating conditions through virtual simulation. Before simulating the operating conditions of the physical bench based on the simulation bench, it is also necessary to map the components, parameters, and behaviors of the physical bench to the simulation bench. However, in the related art, when faced with multiple physical benches, it is impossible to accurately map the physical bench to the corresponding simulation bench, resulting in low accuracy and efficiency of the mapping process. It can be seen that the method of linking virtual and real data models of ship power systems based on digital twins in the related art has the technical problem of low efficiency of bench mapping.

[0028] In order to at least solve some of the above problems, the following Figure 1-Figure 4 The present invention describes the method for linking virtual and real data models of a ship power system based on digital twins.

[0029] The digital twin-based bench mapping method provided in this embodiment can be applied to the scenario of mapping a physical bench to a simulated bench built based on digital twin technology.

[0030] Figure 1 It is a flow chart of the method for linking virtual and real data models of a ship power system based on digital twins provided by the present invention, such as Figure 1 As shown, including but not limited to the following steps: Step 101, obtaining a universal unique identification code of a physical rack; Step 102, constructing a device mapping parsing rule based on the universal unique identifier, wherein the physical rack includes a plurality of physical components, and the device mapping parsing rule is used to define a mapping logic of the plurality of physical components, component parameters, and component behaviors; Step 103, creating a configuration file based on the device mapping parsing rule, wherein each component in the configuration file includes a universal unique identifier; Step 104 : Mapping the physical bench to the simulation bench based on the configuration file, wherein the simulation bench is a digital twin model corresponding to the physical bench.

[0031] Optionally, the configuration file implements data synchronization between the physical bench and the simulation bench through a target communication protocol.

[0032] Optionally, the target communication protocol includes at least one of the following: TCP Socket transmission protocol, UDP Socket transmission protocol.

[0033] It should be noted that the physical test bench in this embodiment is a real test bench, which is used to simulate real working conditions to evaluate the performance, reliability and safety of the ship power system; the simulation test bench is a digital twin model corresponding to the physical test bench.

[0034] Figure 2 Schematic diagram of the virtual-real data model linkage mapping method of the ship power system based on digital twin provided by the present invention, such as Figure 2 As shown, the software architecture of the test bench mapping method based on digital twins of this embodiment may include a data middle platform, a test bench adapter, a simulation adapter, a visualization page and a database. The above software architecture may be set in a server. The test bench operating condition simulation method based on digital twins of this embodiment may be executed by a server or by a data middle platform.

[0035] In this embodiment, a universally unique identifier of a physical rack is obtained; here, a universally unique identifier (UUID) is a software-built standard for assigning a unique identifier to information or an entity. The purpose of UUID is to ensure uniqueness in space and time, that is, any two UUID values ​​are different (excluding intentional conflicts), and the same UUID value will not be generated in the future without foresight.

[0036] Furthermore, a device mapping parsing rule is constructed based on a universal unique identification code, wherein the physical bench includes multiple physical components, and the device mapping parsing rule is used to define the mapping logic of multiple physical components, component parameters and component behaviors; specifically, the corresponding element of each physical component (such as sensor, actuator, controller, etc.) in the simulation bench is determined; how the component parameters (such as temperature, pressure, speed, etc.) are represented in the simulation bench is specified; and the mapping logic of the component behavior is formulated, for example, how a certain action on the physical bench is simulated in the simulation bench.

[0037] Furthermore, a configuration file is created based on the device mapping parsing rule, wherein each component in the configuration file includes a universal unique identifier; specifically, the configuration file may be in XML (eXtensible Markup Language), JSON (JavaScript Object Notation) or YAML (YAMLAin't Markup Language) format, which includes mapping rules; in the configuration file, a unique identifier (such as UUID) is assigned to each physical component, and its corresponding virtual element is defined.

[0038] Furthermore, the physical bench is mapped to the simulation bench based on the configuration file, wherein the simulation bench is a digital twin model corresponding to the physical bench.

[0039] Furthermore, the method of this embodiment may also include a data synchronization step, that is, through a real-time data synchronization mechanism, it is ensured that the state change of the physical rack can be reflected in the simulation rack in a timely manner. Appropriate communication protocols (such as TCP, UDP (User Datagram Protocol) etc.) may be used to transmit data, and an application programming interface (API) may be developed and used to facilitate interaction and data exchange between systems.

[0040] After completing the mapping process, the operating conditions of the physical test bench can be simulated based on the mapped simulation test bench. Specifically, the data middle platform, as a data storage and processing center, undertakes the management and analysis of a large amount of data. By processing, analyzing and storing the received data, the data middle platform provides real-time data support and decision-making basis for the system. The data middle platform extracts historical data into the middle platform through extraction, conversion, and loading processes, or stores operation data in the data middle platform through the HyperText Transfer Protocol Interface (HTTP). The data middle platform also classifies, summarizes and aligns the stored data, and provides a data application programming interface (Application Programming Interface, API) for system use.

[0041] The test bench adapter is used to connect the physical test bench with other systems. The test bench adapter can transmit the operation data collected by the sensor (which may include box pressure data, pump speed data, valve opening data, etc.) through the TCP Socket (Transmission Control Protocol Socket) transmission protocol, and serialize and encode the data generated by the sensor of the physical test bench to obtain a byte sequence. The test bench adapter decodes the byte sequence into JSON (JavaScript Object Notation, a lightweight data exchange format) format and stores it in Rabbit MQ and Redis for visualization system calls. In addition, the test bench adapter encodes the control data serialization JSON model in Rabbit MQ into binary format and sends it to the test bench middleware system to perform test bench operations. It also generates JSON data by decoding the test bench data and puts it into the corresponding Rabbit MQ (Rabbit MessageQueue) queue to realize real-time calls with the gateway, synchronizes information such as pressure, speed, opening to the simulation system according to specific test operations, and stores the sensor pressure, speed, and opening data in the test database. Through the relevant queues of Rabbit MQ, the bench adapter obtains control signal data to ensure effective communication and collaborative work between systems. The bench adapter not only realizes data transmission and conversion, but also ensures data quality and communication protocol adaptation, promoting efficient and stable operation of the system.

[0042] It should be noted that RabbitMQ in this embodiment is an open source message queue system that implements the Advanced Message Queuing Protocol and a distributed protocol for message transmission. It is a middleware used to decouple different services or components in a distributed system, allowing them to communicate by sending and receiving messages without directly calling each other or knowing each other's existence.

[0043] The simulation adapter is responsible for connecting the simulation model with other systems in the display system. Its main functions include dynamically adjusting the simulation input parameters through the REST API (Representational State Transfer Application Programming Interface) of the HTTP interface and the JSON format to achieve flexible configuration of simulation parameters. The simulation adapter can dynamically modify the simulation parameters according to the module name and submodule number to meet the needs of real-time changes. The results calculated by the simulation software will be returned to the message queue and database according to the calculation time frame. The simulation parameter feedback data will be placed in the relevant queue of Rabbit MQ. The simulation results in the queue will be extracted and inserted into the database, or directly used by the visualization system to send the simulated PID (Proportional-Integral-Derivative Controller) adjustment parameters to the test bench system. The simulation adapter not only realizes the real-time transmission and conversion of data, but also ensures the adaptation of data quality and communication protocols, and promotes the effective synchronization and sharing between simulation data and systems.

[0044] The visualization page displays the model working conditions and operation data instruments, and provides interactive functions for users. It is a direct window for providing services to users. Through the virtual display interface, users can watch the actual scene on the visualization page and send practical commands to the physical entity, which will be reflected in real time on the physical bench, realizing efficient collaboration between the simulation software and the physical bench. The virtual display interface uses HTTP REST API and simulation input cards in JSON format for interaction: through REST API, users can communicate through standard HTTP requests to achieve data transmission and control with the simulation software and the physical bench; JSON format is used to transfer data between requests and responses, providing a lightweight and easy-to-parse data exchange format. This combined use method makes the interface flexible and scalable, can meet the needs of different scenarios, and improve the smoothness of visualization page display. At the same time, the operation process data is stored in Redis (Remote Dictionary Serve, in-memory database) to speed up the comparison.

[0045] The database records the twin data such as simulation history data, simulation real-time data, test bench operation real-time data, test bench operation history data, control parameters, etc., which is the basis for the digital twin system to conduct data analysis and provide services. In order to optimize data management, the fields in the database have been set up with rules, and simulation data and real data, historical and real-time data, data from different test benches, etc. can be clearly distinguished, recorded, queried, and read.

[0046] Through the embodiments provided in the present application, a universal unique identification code of a physical test bench is obtained; a device mapping parsing rule is constructed based on the universal unique identification code, wherein the physical test bench includes multiple physical components, and the device mapping parsing rule is used to define the mapping logic of multiple physical components, component parameters, and component behaviors; a configuration file is created based on the device mapping parsing rule, wherein each component in the configuration file contains a universal unique identification code; the physical test bench is mapped to a simulation test bench based on the configuration file, wherein the simulation test bench is a digital twin model corresponding to the physical test bench; the technical problem of low efficiency of test bench mapping in the method for linking virtual and real data models of a ship power system based on digital twins in the related art is solved, thereby improving the efficiency of test bench mapping.

[0047] As an optional solution, the simulation bench includes multiple simulation components, which map the physical bench to the simulation bench based on the configuration file, including: S11, correspondingly associating multiple physical components with multiple simulation components based on the configuration file; S12, synchronizing component parameters of multiple physical components with virtual parameters of multiple simulation components based on the configuration file; S13, defining behaviors of multiple simulation components by using component behaviors of multiple physical components based on the configuration file.

[0048] In this embodiment, multiple physical components are associated with multiple simulation components based on the configuration file; that is, each component of the physical bench is associated with its virtual counterpart in the simulation bench, for example, physical sensor A is mapped to virtual sensor a.

[0049] Furthermore, component parameters of multiple physical components are synchronized with virtual parameters of multiple simulation components based on the configuration file; that is, the consistency between the physical parameters and the virtual parameters is ensured. If the physical sensor in the physical test bench measures temperature, the virtual sensor in the simulation test bench should also simulate the same temperature range and accuracy.

[0050] Furthermore, the component behaviors of multiple physical components are defined based on the configuration file to define the behaviors of multiple simulation components; specifically, it is defined how the physical behaviors are simulated in the virtual system, for example, the movement of the physical actuator may need to be converted into corresponding animations or numerical changes in the virtual environment.

[0051] Through this embodiment, the physical test bench is mapped to the simulation test bench based on the configuration file, which can improve the accuracy of the mapping process, thereby improving the reliability of the virtual-real data model linkage mapping method of the digital twin-based ship power system of this embodiment.

[0052] As an optional solution, after mapping the physical bench to the simulation bench based on the configuration file, the method further includes: S21, obtaining physical bench operation data and simulation bench operation data; S22, determining the parameters to be corrected of the simulation bench based on the performance curves of the physical bench operation data and the simulation bench operation data; S23, updating the parameters of the simulation bench based on the parameters to be corrected.

[0053] Optionally, updating the parameters of the simulation bench based on the parameters to be corrected includes: S31, acquiring historical stability data of the test bench, wherein the historical stability data of the test bench is data corresponding to the parameter to be corrected; S32, updating the flow parameters, speed parameters, lift parameters, and valve opening parameters of the simulation test bench based on the historical stability data of the test bench.

[0054] In this embodiment, after the physical bench is mapped to the simulation bench based on the configuration file, data correction may be performed based on the physical bench operation data and the simulation bench operation data.

[0055] Specifically, the step of correcting the data of the simulation bench by the physical bench in this embodiment may include: modifying the scene simulation card, such as the water tank pressure and water level, pump speed and valve opening and other parameters. The specific work of correcting the data mainly involves the establishment of system model simulation cards, data collection and processing, and parameter consistency comparison and analysis. By comparing the consistency of the performance curves of the actual bench system and the simulation model data, the accuracy and reliability of the simulation system model are ensured; the flow rate, pump speed and pump head of the pump under the historical stable state of the bench are obtained, and the data is transmitted to the data mapping module. After the conversion of the data mapping module is completed, the JSON file is output and sent to the simulation adapter, and the simulation adapter then transmits the data to the simulation bench.

[0056] It should be noted that the simulation card is a hardware device, which is usually used to simulate the behavior of a specific system or environment so as to perform testing, training or research without the need for actual physical equipment. In this embodiment, the simulation card is used to build a simulation bench.

[0057] Through this embodiment, by adding a data correction process, the accuracy of the simulation bench parameters can be improved, thereby improving the reliability of the virtual-real data model linkage mapping method of the digital twin-based ship power system of this embodiment.

[0058] As an optional solution, the digital twin-based gantry mapping method in this embodiment may include the following steps: Step 1: Create a new rack entity. The rack entity contains information such as rack name, rack UUID, rack description, etc. The rack UUID is a unique number generated by the system and sent to the visualization module. When the visualization module accesses it through the interface, it must carry the UUID. The integrated system identifies the rack by the UUID. Therefore, the UUID constructed by the rack system can only be pseudo-deleted and cannot be truly deleted. The UUID must follow the given naming conventions.

[0059] Step 2, select the rack built in the first step, fill in the device table, including the database field, field number, field description, label and automatically generated UUID of the device. The device UUID is the unique number of the rack device, which cannot be modified and is used for mapping later.

[0060] Step 3: In the selected rack, enter the name, description, label and other information of the visualization device, and the system will automatically generate a UUID. The twin UUID is the unique number of the twin and cannot be modified. It is used for mapping later.

[0061] Step 4, select the test bench built in the first step, and fill in the device mapping analysis rules, which include changing the simulation card, obtaining simulation data, analysis type, automatically generated unique UUID, description and remarks. The simulation UUID is the unique number of the simulation build, which cannot be modified and is used for mapping later. The main fields are given by the preset list.

[0062] Step 5: The simulation software can theoretically simulate all test bench behaviors, return simulation data based on the simulation construction model, and unify the fields and units of the simulation data into the same sensor fields of the test bench by mapping subscripts and parsing rules.

[0063] Step 6: The power test bench virtual-real mapping table can be used to output the test bench and simulation sensor comparison parameters to achieve flexible test bench simulation comparison.

[0064] Step 7, by binding the test bench sensor parameters to a simulation card data, realize the data synchronization, remote control and automatic control of the test bench sensor physical quantity and the simulation test bench operation parameters, and realize the control of the virtual with the real.

[0065] Step 8, simulate the behavior of the test bench by launching the simulation software multiple times, and send the PID parameters of the best result to the test bench to achieve virtual control of the real.

[0066] Step 9, based on the configured mapping relationship, open service interfaces such as data synchronization, simulation return, data comparison, remote control, automatic control, optimization control, online correction, and historical data playback, and obtain service data by passing the test bench number and simulation card number.

[0067] It can be understood that in this embodiment, the constructed software configuration bench generates a unique number for each bench, which is similar to the user's unique ID. Through this ID, the bench can be given sensor attributes and a mapping relationship with the simulation system can be established. By using a configuration file to manage the mapping relationship between the bench and the virtual system, the hard-coded method is avoided. This method improves the flexibility of the system, enables the mapping relationship to be quickly accessed and modified, and is easy to maintain and update, especially in long-term use, which helps to trace and record the implementation method at the time, thereby improving the traceability and transparency of the system. At the same time, the system supports the ability to configure multiple benches, allowing users to establish a docking relationship with new simulation software through a simple configuration file. This design significantly speeds up the integration process of the new bench, reduces development time, reduces development costs, and improves the scalability of the system and the flexibility to adapt to different project requirements. For the bench that has been docked, the system allows the user to fine-tune the mapping relationship and display fields through the configuration relationship without changing the code. The method of this embodiment not only improves the user's operating experience, but also provides a higher flexibility for the project team, which can quickly respond to changes in demand and optimize data display and interaction effects.
