[0034] The data generated during the experiment is stored. Experiment reports are automatically generated based on the structured data.

[0035] Test Management System Architecture: The test management system described in this invention adopts a layered architecture design. The overall architecture consists of four layers: presentation layer, application service layer, data persistence layer, and external system integration layer. Each layer communicates with the others through standard interfaces, together forming a complete data management and business processing platform.

[0036] (1) Presentation layer The presentation layer serves as the interface between the system and the user, employing cross-platform technology to support access via both web browsers and mobile devices. The web management interface provides administrators with comprehensive management functions such as data dashboards, equipment management, test task monitoring, and quality issue tracking; the mobile app provides field personnel with on-site operational functions such as instrument connection, test execution, data acquisition, and task reception. This layer utilizes responsive design to adapt to display devices of different sizes, providing a consistent user experience.

[0037] (2) Application service layer The application service layer is the core of the system's business logic. It adopts a microservice architecture, dividing system functions into multiple independent service modules. The test task management service is responsible for the formulation, allocation, and execution tracking of test plans; the equipment management service maintains the ledger information and technical parameters of the tested equipment; the data intelligent analysis service automatically analyzes and determines the compliance of collected data based on preset rules; the quality problem closed-loop management service realizes the entire process tracking of quality problem recording, distribution, processing, and verification; and the test report service automatically generates standardized reports based on structured data.

[0038] (3) Data persistence layer The data persistence layer is responsible for the system's data storage and management, employing a hybrid storage solution combining relational and NoSQL databases. The relational database stores structured data such as device information, experimental tasks, and user permissions; the time-series database specifically stores the large amounts of real-time data collected during the experiment; and the document database stores unstructured data such as experimental reports and images. This layer provides a unified data access interface, enabling efficient reading, writing, and access control for different types of data.

[0039] (4) External system integration layer The external system integration layer is responsible for data exchange and business collaboration with external systems. It interfaces with the State Grid data platform through standardized data interfaces to enable the uploading and sharing of test data; integrates with material management systems such as ECP to automatically acquire equipment procurement information and technical parameters; and interfaces with production management systems to achieve collaboration between test tasks and production plans. This layer uses message queue tools to ensure reliable data transmission and format conversion, guaranteeing data consistency between systems.

[0040] This architecture, through a four-layer separation design concept, achieves high cohesion and low coupling in the system, ensuring its scalability, maintainability, and reliability, and providing a solid technical foundation for the digital management of UHV handover tests.

[0041] System function implementation plan: The system's functional architecture is logically divided into three core layers: the field data acquisition layer, the mobile operation layer, and the cloud management layer. These three layers work together to form a complete functional loop from data source to management decision-making.

[0042] (1) Field data acquisition layer: test instruments + test relay equipment This layer is responsible for interacting with physical devices at the forefront, and its core function is to achieve automatic data collection and standardization.

[0043] Test instrument function: Performs standardized high-pressure tests and generates raw, non-standard measurement results.

[0044] Core functions of the test relay equipment: Multi-source acquisition: Data can be read directly via wired connection or captured by interfaceless instruments via OCR visual recognition.

[0045] Protocol Conversion: Through the built-in protocol library, the proprietary protocol data output by various testing instruments is parsed and converted into unified, structured data within the system.

[0046] This layer unifies the heterogeneous and complex data sources on-site into a regular and usable standardized data stream.

[0047] (2) Mobile operation layer: mobile APP It serves as a bridge connecting the field and the back end, and its core function is to realize the digitalization and control of field operations.

[0048] Bluetooth connection and data reception: The APP connects to the Bluetooth signal of the test relay device and receives standard format test data uploaded by the field acquisition layer in real time.

[0049] On-site operation guidance and control: Show the test task to the test personnel and send control commands to the relay equipment.

[0050] Preliminary data review and upload: Provides a human-computer interaction interface for test personnel to confirm the automatically collected data and submit the complete and confirmed data package (including equipment information, test data, environmental parameters, etc.) to the cloud management layer via mobile network with one click.

[0051] This level empowers on-site personnel with digital tools, enabling them to collect and transmit data instantly, and solidifies work processes within the system.

[0052] (3) Cloud-based management layer: Experimental management system This level is the brain of the system, responsible for data aggregation, processing, and value mining. Its core function is to achieve comprehensive digital management of the experimental business.

[0053] Data Hub and Storage: Receives and stores test data uploaded from all mobile apps, and links it with equipment ledgers and factory test data automatically obtained from material systems such as ECP to form a complete digital archive of equipment.

[0054] Intelligent assessment and alarm: Based on preset procedures and algorithms, the system automatically assesses the compliance of test results and compares them with factory data. Once abnormal or exceeding data is detected, it automatically triggers quality problem recording and generates an alarm.

[0055] End-to-end closed-loop management: Unified scheduling and management of test tasks, personnel, and equipment. In particular, it enables full-process online tracking and closed-loop management of discovered quality issues.

[0056] Automatic report generation and decision support: Based on all structured data, it automatically generates standardized handover test reports with a single click. Simultaneously, it provides managers with a holistic perspective through data dashboards to support decision-making.

[0057] This level achieves the ultimate goal of improving quality, efficiency, and standardization through the digital transformation of the entire process.

[0058] The main functions implemented by the test management system are: (1) Automatic acquisition of physical parameters of main equipment: Through data integration, the physical parameter information of main equipment is obtained from the material procurement process, including equipment type, physical ID, rated voltage, rated capacitance, etc. (2) Standardized management of test templates: In accordance with relevant standards and specifications, standardized customization and management of test templates are carried out, and the measurement part information of the tested equipment is maintained. The UHV substation main equipment is refined to the part level during the handover test stage. Each measurement part of the test equipment is created in the test management system. (3) Test work plan management based on test tasks: Establish a test task review and transfer mechanism at the project manager-test team leader-test personnel level to ensure that test tasks are carried out according to the test plan. Create test tasks: Create test tasks according to the test plan requirements and specify the parameters that need to be measured for each part; (4) Automatic comparison and analysis of test data: Automatically obtain factory test data from the manufacturing process, automatically compare and analyze it with the handover test data of similar tests, and analyze the deviation of test parameters before and after the equipment and the reasons.

[0059] (5) Automatic calculation and analysis of test data: Built-in test analysis rules support configuration and switching of analysis rules for different specifications. After the data acquisition terminal obtains test data from the test instrument, it automatically fills in the data and calculates the formula according to the test template, and automatically analyzes the data according to the analysis rules, and issues warnings for exceeding the threshold. Based on the analysis results, it automatically assigns test conclusions.

[0060] (6) Automatic generation of test reports: The system automatically compiles and generates test reports according to the test tasks, test items and test templates, and automatically formats the test reports according to the test order to generate standardized test report results.

[0061] (7) Closed-loop management of quality issues: Quality issues collected by testing instruments are automatically collected as test reports are generated, and tracked by the on-site team until the loop is closed. The data are then summarized and analyzed to form a quality case library to support the distribution analysis of quality issues.

[0062] (8) Full-process sharing of test data: The handover test data is automatically connected to the engineering operation and material links, supporting the comparative analysis of the handover test data by routine tests in the operation and maintenance links, and the feedback of equipment quality status is fed back to the material links, supporting the evaluation and selection of equipment suppliers.

[0063] This invention adopts Figure 5 and Figure 6 Two methods are used to automatically acquire time instrument data: for test instruments with wired interface communication capabilities, the wired interface method is used for data acquisition; for test instruments without data transmission capabilities, OCR image recognition technology is used for data acquisition.

[0064] The data communication link between the acquisition system and the test management system is as follows: Figure 2 As shown.

[0065] The preferred embodiment of the present invention is applied to the voltage ratio test scenario of the main transformer in an ultra-high voltage substation, and is described in detail below.

[0066] (1) System composition In voltage ratio tests, the traditional method relies on testers to manually record the transformation ratio measurement value displayed on the instrument screen, which has problems such as low efficiency and easy error.

[0067] In this embodiment, the test object is a 1000kV ultra-high voltage main transformer, and the test instrument used is the Baoding Jinyuan JYT(A) type voltage ratio tester. This instrument is connected to the test relay equipment involved in this invention through an RS232 serial interface to realize automatic data acquisition and forwarding.

[0068] (2) Automatic data acquisition workflow The overall process is as follows Figure 3 As shown, the process includes: Data preparation stage: Test personnel create the equipment to be tested in the test management system, entering basic information such as equipment name, manufacturer, and physical ID. The test system retrieves physical parameter data of the equipment from the power grid ECP system based on the physical ID, such as rated capacity and rated transformation ratio. The physical parameter information will be automatically populated into the subsequently generated test report. Test personnel create test tasks in the test management system, which include the equipment to be tested and the test items (including test locations and measured values).

[0069] Test relay equipment configuration phase: The test personnel first select the model of the test instrument to be connected on the test relay equipment. This selection operation activates the corresponding preset data parsing protocol in the equipment, completing the equipment initialization configuration.

[0070] Test execution phase: The test personnel operate the voltage ratio tester to measure the voltage ratio at each tap position under the current winding of the main transformer in sequence. Once the instrument screen displays a stable reading, the single measurement is considered complete.

[0071] Data parsing and storage phase: The test relay equipment reads the raw data output by the instrument in real time via the RS232 interface and converts the raw data into a unified standardized format according to the data parsing logic corresponding to the selected instrument model. The parsed data is temporarily stored in the local storage space of the test relay equipment.

[0072] Data extraction phase: The test personnel launch the mobile app, scan and connect to the test relay device via Bluetooth. In the app, they select the corresponding test project created in the test management system and send a real-time data request command to the device. Upon receiving the command, the test relay device encapsulates the parsed standard data into a Bluetooth communication message and sends it to the app, completing one full data acquisition process.

[0073] (3) Data analysis and quality problem closed loop The process is as follows Figure 4 As shown, during the test, the transformer polarity measurement result was opposite to the factory setting. The automatic judgment function detected the error by comparing the test result with the factory value and alerted the test personnel. The test personnel recorded the problem and found that the cause was an incorrect test wiring, which led to the opposite measurement result. After correcting the wiring and re-measuring, the data was normal, and the test problem was automatically closed.

[0074] (4) Report generation and data integration After the test is completed, the test personnel select the test items in the test management system, and the system automatically generates a test report. The test project manager reviews the test report and related quality issue records in the test management system and integrates the data with the power grid data platform.

[0075] (5) Effect verification To verify the beneficial effects of the present invention, a comparison was made with traditional manual recording methods in the scenario described in this embodiment. The results are as follows:

[0076] The present invention provides a data acquisition system for the handover test of main equipment in high-voltage substation projects, which has the following technical advantages: (1) Comprehensive data acquisition coverage, building a complete data foundation. This invention achieves comprehensive acquisition coverage of all types of data from UHV handover tests by constructing multimodal data acquisition and fusion technology. The system not only integrates industrial interfaces such as RS-232, RS-485, and LAN to directly parse real-time binary messages output by the instruments, but also supports automatic reading and parsing of dedicated data files (such as CSV and DAT formats) generated by the instruments via USB and file interfaces. For closed instruments where data cannot be transmitted externally, the system innovatively introduces machine vision (OCR) assisted acquisition technology. By capturing images of the instrument screen and using dedicated algorithms to accurately identify and extract numbers, characters, and waveform information on the screen, it converts them into structured data. This integrated acquisition scheme of "message parsing, file reading, and image recognition" completely eliminates data blind spots caused by differences in instrument functions, closed interfaces, or security restrictions on-site, achieving truly comprehensive data acquisition without blind spots and providing a solid guarantee for building a high-quality test data foundation.

[0077] (2) Flexible instrument adaptation for efficient ecosystem expansion. Addressing the pain points of diverse instrument models and inconsistent protocols in the field, this invention provides a protocol stack editing function, supporting user-defined communication parameters and data frame parsing rules, enabling rapid adaptation to new equipment. This technology shortens the instrument adaptation cycle from weeks in the traditional development model to hours, significantly reducing system deployment and maintenance costs. Through modular design and protocol template reuse, the system possesses strong ecosystem compatibility and scalability, enabling continuous integration of new instruments as technology evolves, providing key technical support for the large-scale promotion of the solution across multiple regions and organizations.

[0078] (3) Seamless integration of test data across the entire process, with shared access across multiple stages. This invention constructs a two-way integrated data flow from equipment information acquisition to test data upload, enabling unmanned management of test data handover. At the front end of the process, the system automatically acquires complete ledger information, physical parameters, and factory test data of the tested equipment through data interaction with material management systems such as ECP, eliminating the need for test personnel to manually enter equipment information. During test execution, the system automatically completes the test data collection and, based on the structured data from the entire process, integrates the data with the State Grid Corporation's data platform or other subsequent application stages for in-depth data utilization. This two-way integrated model realizes an end-to-end automated data flow from material information to test results and then to advanced applications, breaking down data barriers and laying a solid foundation for equipment lifecycle management and in-depth value mining.

[0079] (4) Quality problem recording and traceability to strengthen precise quality control. The system constructs an automatic quality problem identification and closed-loop management mechanism to achieve traceable and accountable full lifecycle control of UHV equipment testing quality problems. When the intelligent analysis engine detects data anomalies, it automatically requires on-site personnel to create quality problem records, fully record the on-site problem situation, and drive the digital process of "discovery-processing-archiving". This mechanism ensures that the handling process of each quality problem is transparent and the results are traceable, providing a complete data chain for equipment defect analysis and quality management decisions, and strengthening the quality defense line before UHV equipment is put into operation.
