However, most test benches currently still rely on traditional measurement and control technologies, facing many challenges and limitations.

[0003] The existing test benches mainly remain at the traditional measurement and control technology level, and have not formed an effective collaboration mechanism to link test equipment, test data, operation management, data between test benches, engine component information, and subsequent usage status information; in terms of digital transformation, the digitization of existing test benches only realizes data collection and local storage, and the data between test benches form an island effect, making it impossible to reasonably and maximize the use of data.

[0004] Due to the lack of information and digital management, the daily maintenance and management of the test bench equipment need to rely on operators to manually query and record, which makes it impossible to achieve efficient and unified management, resulting in a large waste of human resources. It may also cause safety accidents due to untimely maintenance and replacement of equipment.

[0005] In addition, when repairing the engine, less attention is paid to engine parts information and replacement and repair information; the existing test bench fails to effectively link engine maintenance with engine test data, so that engine repair and maintenance are more dependent on experience, and a lot of time is required to trace the source, resulting in a large waste of human resources.

[0006] Therefore, it is necessary to provide a data management system for a digital test bench to solve the above technical problems. Summary of the invention

Data cannot be shared between test benches, resulting in the inability to conduct multi-system joint testing or comprehensive judgment; 3. Equipment maintenance and management rely on manual operation and lack of automation and digital management tools; 4.

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] The present invention aims at the problems that the existing test bench relies on traditional measurement and control technology and lacks an effective data collaboration mechanism; the digital transformation is limited, the data island phenomenon is serious, the equipment maintenance relies on manual labor and is inefficient; the engine maintenance and test data are poorly correlated, rely on experience, and waste resources. By establishing a data management platform, the data of different test benches are integrated to achieve unified management; by creating an equipment and spare parts information library, status recording and life tracking are achieved to improve maintenance efficiency; by designing an open data platform, different test bench and equipment information is accepted to achieve data association.

[0034] See also Figure 1The present invention provides a data management system for a digital test bench, including a client and a server system; wherein the server system is arranged based on a service-oriented distributed architecture and provides data application system services for the client;

[0035] The service-oriented distributed architecture includes a device layer, an infrastructure layer, a platform layer and an application layer, and each layer is constrained by an interface protocol;

[0036] The equipment layer is composed of several objects, abstracting each digital test bench into an object, extracting test bench data from each object, and performing standardized processing through a data conversion module;

[0037] The infrastructure layer is used to provide computing, storage and network hardware foundations. The server system is distributedly deployed on the infrastructure layer and provides an operating environment and business processing support for the platform layer and application layer.

[0038] The platform layer is used to collect and uniformly manage the test bench data and provide data management services for the application layer;

[0039] The application layer performs data query, data screening, data capture and data publishing on the platform layer, and cooperates with the functional components to realize the data application system; wherein, the data application system includes a device management system and a report management system;

[0040] The client accesses the web page space of the application layer through a graphical interface (the page space is as follows Figure 2 As shown), and call the corresponding data application system service according to the needs.

[0041] It should be noted that: this system achieves unified data management and customized use by building a highly inclusive, scalable and modular server system; supports data conversion customization through data conversion modules, integrates into the data platform, and has strong inclusiveness for data objects; in addition, by providing a unified interface protocol, users can develop applications such as data analysis, which is highly scalable and flexible.

[0042] As a further solution, the equipment layer extracts test bench data from each digital test bench through offline file transfer and / or data extraction of real-time data transmission.

[0043] The offline file transfer method is mainly suitable for test bench systems that were built a long time ago or do not have data publishing functions.

[0044] In this case, the test bench cannot directly transmit data in real time through the network. Therefore, the following steps are used for data transmission:

[0045] Data collection: During the test run, the test bench will generate various data, which will first be collected and stored locally.

[0046] File generation: After the test run, the data is organized into files, usually in a specific data format such as CSV, Excel, or a custom binary format.

[0047] File Transfer: Operators transfer these data files from the test bench to the data center or server via USB drive, network share or other offline methods.

[0048] Data transcoding: In the data center, the system will convert the data in the file into a unified data format according to the preset transcoding rules for further processing and analysis.

[0049] Data storage: The transcoded data is stored in the database for subsequent query, analysis, and application use.

[0050] Real-time data transmission

[0051] The real-time data transmission method is suitable for test benches with data publishing functions or data publishing interfaces. This method can realize the real-time transmission and processing of data. The specific steps are as follows:

[0052] Data collection: The test bench collects data in real time during the test process.

[0053] Data publishing: The test bench sends the collected data to the network in real time through its data publishing function or interface.

[0054] Data reception: A data receiving module is deployed in the data center or server side, which is responsible for receiving the real-time data stream from the test bench.

[0055] Data transcoding: The received data stream is transcoded as needed and converted into a unified data format for the system.

[0056] Real-time processing: The transcoded data can be used by the real-time monitoring system for real-time analysis and early warning, or it can be directly stored in the database.

[0057] Data storage: For data persistence and subsequent use, real-time processed data also needs to be stored in the database.

[0058] As a further solution, in the digital test bench system, the platform layer is the core data management and service provider layer, which is responsible for storing, processing and providing a large amount of data generated by the test bench. In order to effectively manage this data and support complex query and analysis requirements, the platform layer adopts a hybrid database setting.

[0059] A hybrid database combines two different types of databases: a time-series database (TSDB) and a relational database management system (RDBMS).

[0060] Time Series Database (TSDB): This database is specifically designed to handle time series data, that is, data points recorded in time order. In test bench applications, time series databases are used to store continuous, time-stamped test data such as sensor readings, performance indicators, etc. The advantage of time series databases is that they can efficiently insert, store, and retrieve time series data.

[0061] Relational database management system (RDBMS): A relational database is used to store structured data. It organizes data in the form of tables, rows, and columns and supports complex queries and transaction processing. In the test bench system, the relational database is used to manage non-time series data such as the test bench configuration information, equipment information, and maintenance records.

[0062] As a further solution, in the digital test bench system, the design of data structure is crucial because it is directly related to the efficiency of data organization, storage and retrieval. According to the characteristics of the test bench data, the platform layer organizes the data of each field into corresponding data structures for easy management and application;

[0063] The test information index table creates index records for the test, which is convenient for quickly locating and accessing the test data, including the number of test runs, test date, test configuration parameters, and the associated path index of the steady-state data file; the test transient data table is used to record the transient data during the test, such as the instantaneous readings of the sensor, including the number of test runs, the timestamp of the transient data, the data value, etc.; the fault or troubleshooting record table of the tested device is used to record the faults and troubleshooting information of the tested device detected during the test, including the number of test runs, fault description, troubleshooting measures, fault time, etc.; the equipment or sensor measurement information table is used to record the metering information of the system-related equipment and sensors. The measurement information ensures the accuracy of the data, including equipment and sensor number, measurement time, measurement validity period, calibration coefficient, etc. The important component information table records the key component information on the measured part, and provides retrieval information for testing and maintenance. The spare parts information table records the spare parts information required for the maintenance of the measured part, and provides information for spare parts library retrieval. The parts information table records the information of important engine parts, such as manufacturer, model, supplier, usage cycle, maintenance / replacement records, etc. The engine tracking information table records the use information of the engine after it leaves the factory, including factory information, maintenance records, abnormal usage status records, maintenance records, etc.

[0064] As a further solution, in the digital test bench system, the design and implementation of the platform layer depends on a deep understanding of the test bench characteristics. In order to effectively manage and utilize the large amount of data generated by the test bench, the platform layer needs to create corresponding data models, data tables and data charts, and bind and map them with the test bench data.

[0065] By creating data models, data tables and data charts, and binding and mapping them with test bench data, the digital test bench system can achieve effective data management and utilization. This not only improves the operation and maintenance efficiency of the test bench, but also provides strong support for data analysis and decision-making. At the same time, this flexible data model and mapping mechanism also supports system expansion and customization to meet the needs of different test benches and users.

[0066] As a further solution, the equipment management system is a key component of the digital test bench system. It is responsible for monitoring and managing the equipment status, maintenance records, fault information, etc. of the test bench; it provides comprehensive equipment management capabilities for the test bench, thereby improving the reliability, availability and maintenance efficiency of the equipment. Through digital means, the equipment management system can realize automatic monitoring of equipment, fault warning, maintenance planning and inventory management, providing strong support for the stable operation of the test bench.

[0067] The structure of the equipment management system is as follows Figure 3 As shown, the software management module is used to manage the software used in the test bench system, including operating systems, applications, firmware, etc.; the hardware management module is used to monitor and manage the hardware assets of the test bench, including sensors, actuators, controllers, etc.; the fault information management module records and manages the fault information of the test bench equipment to provide support for fault diagnosis and repair; the spare parts library management module manages the spare parts inventory of the test bench to ensure the timely supply of spare parts; the component life management module monitors and manages the service life of key components in the test bench to prevent failures and extend the life of the equipment; the measurement cycle management module manages the equipment and sensors that need to be calibrated or measured regularly in the test bench to ensure the accuracy of the measurement data.

[0068] Report management system such as Figure 3 As shown in the figure, the report management system provides users with a comprehensive and automated report generation and management system; it not only improves the efficiency and accuracy of report generation, but also enhances the ability of data analysis, making the test results more transparent and easy to understand. In addition, through the document management module, users can easily manage and access all documents related to the test, further improving the operation and maintenance efficiency of the test bench.

[0069] In addition, by reserving the report review and approval process interface in the report management system and the standardized application interface in the application layer, the report management system and the application layer can flexibly adapt to future changes in demand and support the addition of new functions and the expansion of existing functions. This design not only improves the maintainability of the system, but also reduces the cost of future upgrades and expansions. At the same time, it also provides users with more choices and flexibility, allowing them to customize and expand the functions of the system according to their specific needs.

[0070] The above embodiments only express preferred implementation modes, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
