Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Implementation Method of Data Acquisition and Control Test System for Intelligent Converged Terminals This embodiment provides a technical solution for a data acquisition and control testing system for intelligent fusion terminals. This system allows for the replacement of testing equipment only by modifying the testing equipment files, without the need to rebuild the testing environment. This reduces the testing preparation work for testing personnel, shortens the testing cycle, and uses relatively standard virtual data, ensuring that the reliability of the test results is not affected by the actual testing environment.

[0029] The system specifically includes various functional modules, including a client, a testing module, a database, and a communication module. The testing module contains various types of virtual test devices used to simulate the functions of corresponding equipment. It is used to select the appropriate virtual test device based on the test device file and generate virtual test data. The test device file contains the selected test device type and operating conditions. The client is used to conduct tests based on test cases; the database is used to store test equipment files, virtual test data, and test cases. The communication module includes a protocol conversion submodule and different types of hardware ports; each hardware port is used to connect to the downlink data acquisition port of the intelligent fusion terminal; the protocol conversion submodule is used to convert virtual test data into test equipment data of the corresponding format according to the test equipment file, and call the corresponding hardware port to interact with the intelligent fusion terminal for data acquisition by the intelligent fusion terminal.

[0030] Therefore, this intelligent fusion terminal data acquisition and control testing system, through its communication module, testing module, and database designed to simulate a test environment, allows the intelligent fusion terminal to acquire data from virtual test equipment. Changing the virtual test equipment only requires modifying the test equipment file; there's no need to rebuild the test environment. The testing process relies on test cases, reducing the test preparation work for testers and shortening the testing cycle. Furthermore, this fully automated data acquisition and control testing system uses virtual test equipment provided by the testing module, eliminating the need for actual equipment. This ensures high consistency of test equipment and avoids data discrepancies caused by different actual equipment, which could affect test results. Simultaneously, as long as the virtual equipment's parameter configuration is consistent, repeated testing is possible, facilitating the reproduction and analysis of difficult problems. Based on this, when setting up test environments for different types of testing equipment, complex wiring is unnecessary; simply connect the intelligent fusion terminal's data acquisition port to the corresponding port in the system's communication module. Adding test equipment also does not require changing the intelligent fusion terminal's wiring, further reducing the workload for testers and completely eliminating cumbersome and redundant wiring.

[0031] Specifically, in this embodiment, the client conducts testing based on test cases by: issuing control commands to the intelligent fusion terminal according to the test cases, parsing the collected data reported by the intelligent fusion terminal, comparing it with the virtual test data stored in the database, judging the accuracy of the data collection by the intelligent fusion terminal, and obtaining the test results.

[0032] In existing technologies, determining the accuracy of data collection from intelligent fusion terminals typically takes up more than 40% of the entire testing cycle. However, in this embodiment, the collected data reported by the intelligent fusion terminal is converted from virtual test data stored in the database. Based on this, the accuracy of the data collection is determined by directly comparing the collected data reported by the intelligent fusion terminal with its standard data source (i.e., the virtual test data stored in the database). This eliminates the need for manual data verification, significantly reduces the overall testing cycle, and improves testing efficiency. It also avoids the uncertainties introduced by manual data verification, ensuring the accuracy of the test results.

[0033] In one specific embodiment, the client conducts fully automated testing based on test cases, issues control commands to the intelligent fusion terminal, parses the collected data reported by the intelligent fusion terminal, compares it with the virtual test device data (i.e., virtual test data) in the database, judges the accuracy of the data collection by the intelligent fusion terminal, and automatically generates a test report in a specified format.

[0034] Additionally, refer to Figure 2 The client includes a human-computer interaction interface for users to configure test equipment files containing the selected test equipment type and operating conditions; the client also allows users to add, modify, or delete test cases for data acquisition and control functions, as well as configure parameters for the communication module.

[0035] Furthermore, referring to Figure 3 The functional modules also include a topology module; Reference Figure 4 The communication module also includes a topology identification circuit; the topology identification circuit is used to store the acquired topology identification signals into a database for the topology module to call for calculation and analysis. The topology module is used to calculate the topology and hierarchical relationship based on the test equipment files obtained from the database, and combined with the topology identification signal in the database, to calculate and generate characteristic current data in real time. The communication module is also used to send the characteristic current data calculated by the topology module to the intelligent fusion terminal via the topology identification circuit.

[0036] Therefore, the topology module can calculate the topology and hierarchical relationship based on the test equipment file, and analyze the characteristic current signal obtained by the topology identification circuit of the communication module, and generate characteristic circuit signal data accordingly.

[0037] And, similarly refer to Figure 4 The hardware ports include at least two of the following: virtual carrier module, low-power wireless module, Bluetooth module, LoRa, CAN and RS485 ports. Test device data for the corresponding interfaces are sent to each hardware port via USB Hub to call the corresponding hardware port to interact with the smart fusion terminal.

[0038] In a preferred embodiment, the communication module mainly consists of two parts: hardware and software. The hardware part mainly comprises a USB hub and virtual carrier module, a topology identification circuit, a low-power wireless module, a Bluetooth module, LoRa, CAN, RS485, etc.; each hardware port is connected to the corresponding downlink data acquisition port of the intelligent fusion terminal. The software part mainly undertakes protocol conversion functions, matching and converting data in the database into test equipment data of the correct format based on the test files, and calling different hardware interfaces to interact with the intelligent fusion terminal. The topology identification circuit stores the topology identification signal (i.e., the topology identification signal emitted by the topology identification module of the fusion terminal) into the database for the topology module to call for calculation and analysis; and sends the calculation results of the topology module to the fusion terminal via the topology identification circuit.

[0039] Specifically, refer to Figure 5 The topology module is also used to calculate the topology and hierarchical relationship based on the test cases, generate the existing topology diagram, and send it to the topology display page in the human-computer interaction interface for real-time display of the topology during the test process. The topology module is also used to send various test devices as icons to the topology display page in the human-computer interaction interface, allowing users to add or delete test devices by dragging and dropping, and manually draw the topology network; it is also used to automatically add or delete the corresponding test device files to the database based on the user's addition or deletion of test devices.

[0040] In a preferred embodiment, the topology module primarily undertakes real-time topology calculation and characteristic current data generation functions. On one hand, it can generate existing topology diagrams based on test cases and display them in real-time through the topology display page in the human-machine interface, thereby showing the topology status during the test process. For example, when a smart circuit breaker trips, the circuit breaker and its subordinate devices in the topology diagram turn gray, indicating a change in the branch topology structure. On the other hand, the topology display page displays various test devices in the form of icons. Users can add or delete test devices by dragging, pulling, and dropping, and manually draw the topology network. At the same time, the topology module can obtain the user's operation of adding or deleting test devices and automatically add or delete test device files to the database, achieving real-time file updates and facilitating the rapid construction of a simulation test environment.

[0041] In this embodiment, the client provides a human-computer interaction interface, data processing, control command issuance, and topology display functions. The client's human-computer interaction interface allows configuration of other functional modules (such as the status, type, parameters, and variables of the communication module, topology module, and testing module); the client can also add, modify, delete, and archive test cases for the data acquisition and control functions.

[0042] In this embodiment, refer to Figure 3 and Figure 6 The virtual test equipment in the test module includes: A virtual distribution transformer status sensor used to simulate data on oil temperature, oil pressure, oil level, and gas protection status of oil-immersed transformers; A virtual meter used to simulate the real-time usage or historical data of the metered objects, including electricity, water, gas and heat; This is used to simulate a virtual charging pile, including data on the output voltage, charging output current, and current charging status of the charging pile. A virtual distributed power access unit used to simulate data including voltage, current, active power, reactive power, power factor, basic information of photovoltaic power plants, and inverter operating status of distributed photovoltaic inverters; A virtual fuse used to simulate voltage, current, and temperature data of the fuse; A virtual smart circuit breaker used to simulate the circuit breaker's open / closed status, residual current value, voltage, current, and event alarm data; A virtual three-phase imbalance control device used to simulate voltage, current, three-phase imbalance and commutation status data including commutation switches; A virtual line regulator used to simulate voltage, current, power factor, and tap data at both the input and output terminals of the regulator; A virtual static var compensator used to simulate data including voltage, current, power factor, and switching status of the compensation device; A virtual intelligent capacitor device used to simulate capacitor capacitance, switching status, and common and individual compensation voltage data; Virtual station power environment equipment used to simulate temperature, humidity, water level, and smoke detection data, including those from distribution boxes or distribution rooms; A virtual image acquisition device that stores images of abnormal operation conditions inside the power distribution station room for intelligent fusion terminals to acquire images; Each virtual testing device contains corresponding virtual testing device information. These virtual testing devices can simulate various commonly used testing devices, thereby broadening the scope of testing, increasing applicability, and making the testing items more comprehensive.

[0043] Reference Figure 7 Virtual test data includes real-time data, frozen data, and event logs from the virtual test equipment; The virtual test equipment information includes basic information about the virtual test equipment and communication parameters. The basic information includes the type, quantity, serial number, and communication address of the virtual test equipment. The communication parameters include the communication protocol and required parameters for communication.

[0044] In practice, the database categorizes and archives data from all functional modules of the test system, managing it uniformly. Specifically, in a preferred embodiment, the database is responsible for the following storage functions: 1) Responsible for storing the client configuration test device files, test cases, and data and interaction messages reported by the intelligent fusion terminal; 2) Responsible for storing the characteristic current information (i.e., topology identification signal) received by the communication module; 3) Responsible for storing the real-time topology and hierarchical relationships of the transformer area calculated by the topology module, as well as the generated characteristic current data information; 4) Responsible for the type, quantity, number, communication address, communication protocol, communication parameters, operating conditions, real-time data, frozen data, event logs, etc. of virtual test equipment in the storage area.

[0045] Reference Figure 3 The data acquisition and control test system of the intelligent fusion terminal in this embodiment has a built-in MQTT message queue. The data interaction between each functional module is realized through the subscription and publication of relevant messages in the MQTT message queue. Each functional module subscribes to other functional modules. The database is also used to store MQTT data exchange messages between various functional modules within a set time window, which facilitates problem tracing and analysis.

[0046] Implementation Methods for Data Acquisition and Control Testing of Intelligent Converged Terminals This embodiment provides a technical solution for a data acquisition and control testing method for intelligent fusion terminals.

[0051] In addition, the client includes a human-computer interaction interface for users to configure test equipment files containing the selected test equipment type and operating conditions; the client also allows users to add, modify, or delete test cases for data acquisition and control functions, as well as configure parameters for the communication module.

[0052] Furthermore, the functional module also includes a topology module; the communication module also includes a topology identification circuit; the topology identification circuit is used to store the acquired topology identification signals into a database for the topology module to call for calculation and analysis; The topology module is used to calculate the topology and hierarchical relationship based on the test equipment files obtained from the database, and to generate characteristic current data in real time by combining the topology identification signals in the database.

[0056] Specifically, the topology module is also used to calculate the topology and hierarchical relationships based on the test cases, generate an existing topology diagram, and send it to the topology display page in the human-computer interaction interface for real-time display of the topology during the test process. The topology module is also used to send various test devices as icons to the topology display page in the human-computer interaction interface, allowing users to add or delete test devices by dragging and dropping, and manually draw the topology network; it is also used to automatically add or delete the corresponding test device files to the database based on the user's addition or deletion of test devices.

[0057] In a preferred embodiment, the topology module primarily undertakes real-time topology calculation and characteristic current data generation functions. On one hand, it can generate existing topology diagrams based on test cases and display them in real-time through the topology display page in the human-machine interface, thereby showing the topology status during the test process. For example, when a smart circuit breaker trips, the circuit breaker and its subordinate devices in the topology diagram turn gray, indicating a change in the branch topology structure. On the other hand, the topology display page displays various test devices in the form of icons. Users can add or delete test devices by dragging, pulling, and dropping, and manually draw the topology network. At the same time, the topology module can obtain the user's operation of adding or deleting test devices and automatically add or delete test device files to the database, achieving real-time file updates and facilitating the rapid construction of a simulation test environment.

[0058] In this embodiment, the client provides a human-computer interaction interface, data processing, control command issuance, and topology display functions. The client's human-computer interaction interface allows configuration of other functional modules (such as the status, type, parameters, and variables of the communication module, topology module, and testing module); the client can also add, modify, delete, and archive test cases for the data acquisition and control functions.

[0059] In this embodiment, the virtual testing equipment in the testing module includes: A virtual distribution transformer status sensor used to simulate data on oil temperature, oil pressure, oil level, and gas protection status of oil-immersed transformers; A virtual meter used to simulate the real-time usage or historical data of the metered objects, including electricity, water, gas and heat; This is used to simulate a virtual charging pile, including data on the output voltage, charging output current, and current charging status of the charging pile.

These virtual testing devices can simulate various commonly used testing devices, thereby broadening the scope of testing, increasing applicability, and making the testing items more comprehensive.

[0060] Virtual test data includes real-time data, frozen data, and event logs from the virtual test equipment; The virtual test equipment information includes basic information about the virtual test equipment and communication parameters. The basic information includes the type, quantity, serial number, and communication address of the virtual test equipment. The communication parameters include the communication protocol and required parameters for communication.

[0061] In practice, the database categorizes and archives data from all functional modules of the test system, managing it uniformly. Specifically, in a preferred embodiment, the database is responsible for the following storage functions: 1) Responsible for storing the client configuration test device files, test cases, and data and interaction messages reported by the intelligent fusion terminal; 2) Responsible for storing the characteristic current information (i.e., topology identification signal) received by the communication module; 3) Responsible for storing the real-time topology and hierarchical relationships of the transformer area calculated by the topology module, as well as the generated characteristic current data information; 4) Responsible for the type, quantity, number, communication address, communication protocol, communication parameters, operating conditions, real-time data, frozen data, event logs, etc. of virtual test equipment in the storage area.

[0062] The data acquisition and control test system of the intelligent fusion terminal involved in this embodiment has a built-in MQTT message queue. The data interaction between each functional module is realized through the subscription and publication of relevant messages in the MQTT message queue. Each functional module subscribes to other functional modules. The database is also used to store MQTT data exchange messages between various functional modules within a set time window, which facilitates problem tracing and analysis.

[0063] It should be understood that the above-described specific embodiments of the present invention are merely illustrative or explanatory of the principles of the present invention, and do not constitute a limitation thereof.
