The digital twin model of measurement and control equipment needs a reliable and effective calling method to support the service platform in providing external services. The method disclosed in this invention includes the design of a model parameter acquisition module, a model-driven module, a data integration module, and an interface encapsulation module. First, the model parameter acquisition module analyzes the digital twin model of the measurement and control equipment to obtain parameter files for model management. Then, the model-driven module addresses the problems of long model simulation time and difficulty in managing multi-software collaborative simulation, while the data integration module addresses the problems of non-standard data formats and difficulty in transmitting scattered data. This invention can be used by the digital twin service platform to call the digital twin model and, to a certain extent, maintain the normal operation of the digital twin model, improving the usability of the digital twin model of measurement and control equipment.

[0038] The structural block diagram of the present invention is as follows: Figure 1 As shown, the specific implementation method is as follows:

[0039] Step (1): Search for controllable parameters in the files of the digital twin model of the measurement and control equipment, and organize them into a structured model parameter file. The controllable parameters refer to parameters that can be adjusted externally before the model runs without affecting the model's functionality and correctness. The model parameter file is a file written using markup languages ​​such as XML and HTML, used to describe the controllable parameter's name, associated statement, adjustable range, adjustment method, and other attributes. The specific implementation is as follows:

This validity validation refers to the initialization condition set. Do the elements satisfy the model parameter file? Requirements. If the initialization condition set If an invalid element is found, an error message is returned and step (2) ends; in all initialization condition sets When an element is valid, it is configured into the digital twin model of the measurement and control equipment one by one;

[0045] Step (2.3): For single-platform simulation models, directly run the driver; for multi-platform co-simulation models, first check if the model call request specifies the model startup order. If it does, start the model according to the requirements. If not, start the model in descending order of model files and record the startup order. The platform refers to the software, programs, etc., on which the model relies during operation. It monitors the computing resources used by the model during runtime to prevent errors due to insufficient resources.

[0046] Step (3): During and after the model's operation, the results are collected, formatted, and integrated to obtain standardized data files. The operation results refer to the output files obtained by each part of the model after completing its task, and the formatting refers to the process of organizing the output files into a specified, uniform format. Specific implementation is as follows: Figure 3 As shown, the steps are as follows:

[0047] Step (3.1): Obtain the model execution results: Based on the output content during and after the model execution, classify the models into those capable of outputting in file formats. A model that lacks file format output capability but possesses data stream output capability. A model that lacks both file format output capability and data stream output capability. .against Collect the model's output files after the model finishes running. common 1, forming a set of output files . Each data stream output is sequentially stored in the database according to its timing relationship, resulting in... Data files , forming a data file collection ,against The design monitoring program converts the data from the model simulation process into... Each data stream is output and stored sequentially in the database according to its timing relationship. Data files , forming a data file collection ;

[0048] Step (3.2): Format the output results in both the file format and the output results stored in the database. Extract each output file.

[0049] Step (3.3), Integration of running results: according to the model calling order Based on the requirements in the model call request, the standard format file set obtained in step (3.2) is... Perform uniform naming and compression operations to obtain the output file. The unified naming refers to... The data is named in a standardized format: "Number-Model Name-Run Completion Time" for easy sorting. Compression is performed to facilitate data file transfer and reduce bandwidth consumption.

[0050] Step (4) Encapsulate the interface of the digital twin model of the measurement and control equipment: Encapsulate the interface functions of steps (1) to (3) to construct an interface method for receiving model call requests and sending model call results, thereby obtaining an interface that can be remotely or locally called by the digital twin service platform. The specific process is as follows:

The input to the function in the encapsulated implementation step (3) is the model startup sequence. The digital twin model call request outputs as follows: ;

[0052] Step (4.2), Constructing the External Interface: Based on the functional functions encapsulated in Step (4.1), design the model's URL, HTTP method, request parameters, request body, and response body. The request parameters must include the identifier of the digital twin service platform initiating the call; the request body must include a JSON-formatted model call request describing the model's initial parameters, call order, and output order; the response body must include a JSON-formatted directory of the model's execution results files. Files are transferred via SFTP, SCP, or other methods.
