[0002] The statements in this section are provided only as background information in connection with this disclosure and may not constitute prior art.

[0003] The operational examination for metrology personnel certification is a core mechanism for ensuring the technical level and quality safety of the metrology industry. Traditional methods of operational training and assessment for metrology personnel mainly rely on physical equipment, which has problems such as expensive equipment, high costs due to the number of sets required for training, limited training content for specific equipment models, inefficient and subjective assessment processes relying on manual evaluation, and complex setup of physical operation environments.

[0004] While some virtual simulation training systems exist, most are single-function and cannot achieve a complete closed-loop process from setting exam data to presenting virtual devices and reviewing exam records. They lack a comprehensive assessment of the correctness of electrical connections of equipment and have poor scalability, making it difficult to adapt to the assessment needs of different types of measuring equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a virtual simulation system and method for training and assessing the operational skills of metrology personnel, thereby solving the technical problems existing in the prior art, such as high equipment cost, low training efficiency, strong subjectivity in assessment, and poor system scalability.

The modular verification training program runs on the virtual simulation base and is used to train and assess trainees' metrological operation skills. The AI-assisted review module uses OCR technology and AI algorithms to automatically identify and analyze students' operation records.

[0007] Furthermore, the examination process management platform and the virtual simulation base for measurement operations adopt a C / S architecture combined with dynamic libraries and data bus technology, or a B / S architecture combined with microservice technology to achieve high scalability.

[0008] Furthermore, the modular reusable connector simulation panel consists of a reusable panel, a controller, a housing, and quick-installation bolts; the housing and controller have unified installation and electrical interfaces, the reusable panel is customized according to the requirements of the verification project, and is quickly connected to the controller through connectors, and the structure is fixed by quick-installation bolts.

[0009] Furthermore, the modular verification training program includes: The exam data configuration module is used to configure exam environment information, equipment information, and assessment item content, and to generate verification record templates in batches. The assessment module for verification standards and basic knowledge is used to assess trainees' mastery of basic verification knowledge. The verification item selection assessment module is used to assess trainees' ability to select verification ranges and verification points. The device connection assessment module supports two connection methods: software simulation connection and physical connector panel connection.

[0010] Furthermore, the device connection assessment module simulates a real wiring environment through virtual wiring software, supports the free selection and combination of various cables and connectors, and is jointly developed using C++ and QML, with C++ responsible for the algorithm and QML responsible for the interface implementation.

[0011] Furthermore, the AI-assisted review module uses OCR technology to identify the verification record data submitted by trainees and automatically compares it with preset standard values ​​to complete batch review.

[0012] Furthermore, the system uses an SQLite database to store assessment project data, virtual wiring data, and unit conversion data; the database includes an assessment project database, a virtual wiring database, and a unit conversion database.

[0013] This invention also proposes a virtual simulation method for training and assessing the operational skills of metrology personnel.

[0014] Furthermore, in step S2, device connection and operation can be completed through virtual connection via software interface or through physical connector simulation panel, and the system collects physical wiring status in real time through serial communication.

[0015] Furthermore, the auxiliary review module uses artificial intelligence algorithms for OCR recognition and data analysis to achieve automatic review of assessment results.

[0016] Compared with existing technologies, the advantages of this invention are: 1. Through the highly scalable virtual simulation base design, the system can flexibly adapt to various metrological verification projects, supports both C / S and B / S architectures, and facilitates the expansion and maintenance of system functions; 2.

Detailed Implementation

[0018] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0019] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0020] Example 1 like Figure 1 As shown, the virtual simulation system provided in this embodiment of the invention mainly consists of three core parts: a highly scalable virtual simulation base, a modular verification and training program running on it, and an artificial intelligence-assisted review module.

[0021] The highly scalable virtual simulation platform adopts a modular design, supporting both C / S and B / S architectures. In the C / S architecture, dynamic libraries and data bus technology are used to achieve communication between modules; in the B / S architecture, microservice technology is used to break down system functions into multiple independent microservices that communicate via APIs. This design gives the system excellent scalability and maintainability.

[0022] like Figure 2As shown, the modular, reusable connector simulation panel consists of a reusable panel, a controller, a housing, and quick-installation bolts. The housing and controller use standardized mechanical and electrical interfaces. The reusable panel is customized according to specific metrological verification projects, and various connectors corresponding to the interfaces of real equipment are installed on it. When a specific project assessment is required, simply select the corresponding customized panel, quickly connect it to the controller via connectors, and use the quick-installation bolts to fix the panel to the housing to rapidly build the required equipment interface simulation environment.

[0023] The modular verification training program includes multiple functional modules: the examination data configuration module provides a graphical interface, allowing instructors to configure various parameters required for the assessment; the verification specifications and basic knowledge assessment module presents theoretical questions in the form of multiple choice and true / false questions to examine trainees' mastery of relevant verification procedures, safety regulations, and basic metrological knowledge; the verification item selection assessment module allows trainees to select verification items, ranges, and verification points in a virtual simulation environment; the equipment connection assessment module supports two assessment modes: pure software simulation and physical connection mode; the equipment operation module provides a highly realistic virtual instrument interface that records all trainees' operational actions and timing; and the behavior detection algorithm analyzes trainees' operational sequences, operation intervals, and whether key steps are missing or incorrectly ordered to provide real-time evaluation and scoring of the standardization, proficiency, and compliance of their operation process.

[0024] like Figures 3a-3c As shown, the virtual wiring module is jointly developed using C++ and QML. C++ is used to develop the algorithm, while QML is used to develop the interface. The virtual wiring software simulates a real wiring environment, providing connection methods for standard devices and devices under test. It supports various types of cables and connectors, and trainees can complete device connections by dragging and dropping. The system automatically detects whether the connection is correct and will provide a prompt message if an error is found.

[0025] like Figures 4a-4k As shown, the physical wiring module consists of two parts: hardware and software. The hardware includes a controller, a junction box, and a wiring panel; the software is developed based on the Qt framework and utilizes the serial communication library provided by Qt to exchange data with the control board in real time via a serial port. The module employs data verification and processing technology to ensure the accuracy and reliability of the data.

[0026] The system uses an SQLite database to manage three types of data: the assessment project database stores the multiple-choice questions, answers, practical projects, and selection data for each project; the virtual wiring database manages information on equipment, connectors, and interface types; and the unit conversion database is used for data unit conversion.

[0027] The AI-assisted review module first uses OCR technology to automatically identify handwritten or printed data in the electronic record sheets or scanned paper record sheets submitted by students. Then, it automatically compares the identified data with the standard values ​​and allowable error ranges set by the teacher. Through preset judgment rules, it quickly and objectively completes the batch evaluation of the correctness of all test point data.

[0028] Please see Figure 5 and Figure 6 The present invention also provides a method for training and assessing the operational skills of metrology personnel based on the above system, comprising the following steps: the teacher configures the assessment parameters through the examination data configuration module; the trainee completes the basic knowledge assessment, verification item selection, equipment connection and operation in a virtual simulation environment; the system scores the trainee's operation process in real time through a behavior detection algorithm; after the trainee completes the operation, the auxiliary review module automatically identifies and analyzes the recorded data and generates the assessment results.

[0029] This invention effectively solves the problems of high cost, low efficiency, poor versatility, and strong subjectivity of traditional methods by using a highly scalable base design, modular assessment items, virtual-physical connection assessment, and artificial intelligence-assisted evaluation. It provides an efficient, economical, and reliable solution for the training and assessment of metrology personnel.

[0030] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.

[0031] This background section is provided to generally present the context of the invention. The work of the currently named inventors, the work to the extent described in this background section, and aspects of this section that did not constitute prior art at the time of application are neither expressly nor impliedly acknowledged as prior art to the invention.
