[0031] Embodiment One

[0032] Figure 1 A structural schematic diagram of a test system of a relay protection device according to Embodiment One of the present application is provided, as shown in Figure 1 The system includes a test platform module 110, a data forwarding module 120, and a device test module 130.

[0033] The device test module 110 is connected with the data forwarding module 120, and is configured to collect initial test data fed back by a relay protection device in executing at least one test task, and upload the initial test data to the data forwarding module 120; the data forwarding module 120 is connected with the test platform module 130, and is configured to receive the initial test data, perform data conversion processing on the initial test data to obtain to-be-analyzed test data, and send the to-be-analyzed test data to the test platform module 130; and the test platform module 130 is configured to perform data analysis on the to-be-analyzed test data received based on a multi-task processing mechanism to obtain a data analysis result, and determine a test result corresponding to the relay protection device based on the data analysis result.

[0034] The test task can be understood as a test task of the relay protection device issued by the interactive interface. The initial test data can be understood as the to-be-analyzed test data. The to-be-analyzed test data can be understood as original data directly generated by the device under test (such as the relay protection device) in executing a specific test task in the device test process without any processing or conversion. The to-be-analyzed test data can be understood as test data waiting for data analysis after data processing.

[0035] Specifically, the device test module collects initial test data fed back by the relay protection device after executing a series of test tasks. The initial test data is uploaded to the data forwarding module. The initial test data can include current, voltage, switch state, and fault indication, and other key information. The data forwarding module is responsible for receiving the initial test data from the device test module, and performing a series of preprocessing operations such as data cleaning, format conversion, data verification, etc. on the initial test data to obtain to-be-analyzed test data. The test platform module starts a data analysis process based on a multi-task processing mechanism, which can include multiple steps such as data preprocessing, feature extraction, model training, prediction analysis, etc. The target information related to the performance, state or behavior of the relay protection device is extracted for subsequent evaluation and decision-making. After in-depth analysis, the test platform module generates a data analysis result. The data analysis result can be presented in the form of charts, reports, and logs, and contains detailed information about device performance, fault mode, potential risks, etc. Based on the data analysis result, a test result corresponding to the relay protection device is further determined. The test result can include the qualified / unqualified state of the device, the performance level, the fault type and location, etc.

[0036] Optionally, the test platform module comprises a priority determination unit, a data division unit, a data analysis unit and a test result determination unit, wherein the priority determination unit is configured to determine a time priority corresponding to each test task respectively in a case where the test data to be analyzed fed back by the relay protection device in executing a plurality of test tasks is received; the data division unit is configured to divide the test data to be analyzed fed back by the plurality of test tasks into first test data to be analyzed and second test data to be analyzed based on the time priority and a preset time priority division threshold; the data analysis unit is configured to analyze the first test data to be analyzed based on a first processor core to obtain a first data analysis result, and analyze the second test data to be analyzed based on a second processor core to obtain a second data analysis result; and the test result determination unit is configured to determine a test result corresponding to the relay protection device based on the first data analysis result and the second data analysis result.

[0037] Among them, the first test data to be analyzed can be understood as the test data to be analyzed of non-real-time tasks, and the second test data to be analyzed can be understood as the test data to be analyzed of real-time tasks.

[0038] Specifically, the priority determination unit determines a time priority for each test task when receiving the test data to be analyzed fed back by the relay protection device after executing a plurality of test tasks. The time priority can be set based on the urgency, importance, expected completion time, and other factors of the test task. Each test task is evaluated based on a preset priority evaluation rule and assigned a corresponding priority value. The priority value can be a number, level, or category for subsequent data division and processing. The data division unit divides the test data to be analyzed fed back by the plurality of test tasks into first test data to be analyzed and second test data to be analyzed based on the time priority provided by the priority determination unit and a preset time priority division threshold. It ensures that high-priority test data can be processed and analyzed first. Compare the time priority of each test task with the preset threshold. If the time priority is higher than or equal to the threshold, the corresponding test data is divided into first test data to be analyzed; if the time priority is lower than the threshold, the corresponding test data is divided into second test data to be analyzed. The data analysis unit uses different processor cores to analyze the divided test data to be analyzed. For the first test data to be analyzed, a first processor core is used for analysis and a first data analysis result is obtained; for the second test data to be analyzed, a second processor core is used for analysis and a second data analysis result is obtained. It ensures that high-priority tasks can be processed faster. The data analysis unit can include multiple data processing channels or threads, each associated with a specific processor core. When receiving test data to be analyzed, the unit will assign it to the corresponding processing channel or thread for processing according to the category of the data (first or second test data to be analyzed). The test result determination unit determines the test result corresponding to the relay protection device based on the first data analysis result and the second data analysis result provided by the data analysis unit. Finally, a test result report is generated, which lists the results of each test task and the overall evaluation in detail.

[0039] In the embodiments of the present application, the test platform module can efficiently process and analyze data from a plurality of test tasks of the relay protection device, ensure that high-priority tasks are processed first, and optimize resource utilization and improve analysis efficiency.

[0040] Optionally, the first processor core and the second processor core are integrated in one processor. The first processor core and the second processor core interact with each other based on an asymmetric multiprocessing framework.

[0041] Optionally, the test platform module includes a report display unit, wherein the report display unit is configured to generate a test report based on the test result after determining the test result corresponding to the relay protection device, and display the test report.

[0042] Specifically, after the test platform module completes data analysis on all test tasks and determines the test results corresponding to the relay protection device, the report display unit automatically generates a test report according to the test results. The report can include test tasks, test data, data analysis results, and test result summaries, etc. The generated test report is displayed to the user through the interactive interface.

[0043] In the embodiment of the application, the report display unit is responsible for generating and displaying the test report, so that the user can clearly and intuitively view the results of the test process, and the user's use experience is improved.

[0044] Optionally, the system further comprises a time calibration module.

[0045] The time calibration module is configured to determine initial acquisition time data corresponding to the initial test data, and calibrate the initial acquisition time data based on a time calibrator to obtain target acquisition time data corresponding to the initial test data.

[0046] The initial acquisition time data can be understood as the time data of acquiring the initial test data. The target acquisition time data can be understood as the time data of acquiring the initial test data after calibration.

[0047] Specifically, the time calibration module obtains initial acquisition time data associated with the initial test data from the device test module or the data forwarding module. The initial acquisition time data records the specific time when the test data is acquired. The initial acquisition time data is calibrated based on the built-in time calibrator. The time error caused by device clock deviation, network delay or other factors is eliminated, so as to ensure the accuracy and consistency of the time data. After calibration, the time calibration module generates target acquisition time data corresponding to the initial test data. The time calibration module can include one or more time calibrators for providing a standard time reference. These calibrators can maintain their accuracy by periodically synchronizing with an external time source (such as a network time server).

[0048] In the embodiment of the application, the time calibration module can eliminate the time error caused by device clock deviation or other factors, thereby improving the accuracy of the time data. The calibrated time data can be consistent throughout the system, which helps to ensure the accuracy and reliability of data analysis, test report generation and other tasks. The time calibration module provides necessary time reference and calibration functions.

[0049] Optionally, the test platform module comprises an instruction set processor, and the data forwarding module comprises an FPGA logic processor; the instruction set processor and the FPGA logic processor are connected through a PCIe communication bus.

[0050] The instruction set processor is configured to process preset instructions, and further configured to process instructions with a length less than or equal to a preset length.

[0051] Optionally, the device testing module comprises a power amplifier, the power amplifier is integrated with a current power device and a voltage power device; the data forwarding module further comprises a digital-to-analog converter and an analog-to-digital converter; the power amplifier is connected with the digital-to-analog converter and the analog-to-digital converter respectively.

[0052] The technical scheme of the embodiment of the application is characterized in that the device testing module is connected with the data forwarding module, and is configured to collect initial test data fed back by a relay protection device during execution of at least one test task, and upload the initial test data to the data forwarding module; the initial test data generated during execution of a test task is collected in real time, so that the accuracy and timeliness of the data are ensured; then, the data forwarding module is connected with the test platform module, and is configured to receive the initial test data, perform data conversion processing on the initial test data to obtain test data to be analyzed, and send the test data to be analyzed to the test platform module; the initial test data is converted to obtain test data to be analyzed which is uniform in format and easy to analyze, thereby providing convenience for subsequent data analysis; finally, the test platform module is configured to perform data analysis on the test data to be analyzed received based on a multi-task processing mechanism, to obtain a data analysis result, and determine a test result corresponding to the relay protection device based on the data analysis result. The test data to be analyzed can be processed simultaneously, so that the efficiency and throughput of data analysis are improved. The problems of low test efficiency and low accuracy of the relay protection device are solved, and the beneficial effects of improving the test efficiency and accuracy of the relay protection device are achieved.

[0053] Embodiment two

[0054] Figure 2a A structure diagram of a test system of a relay protection device is provided for the embodiment two of the application, the embodiment is optimized on the basis of the above-mentioned embodiment, and the test system of the relay protection device provided by the embodiment comprises a test platform module 210, a data forwarding module 220, a transmission strategy determination module 230 and a device testing module 240.

[0055] The transmission strategy determination module 230 is configured to acquire first network state data, determine a data type of the test data to be analyzed for each test data to be analyzed, determine a transmission priority corresponding to the test data to be analyzed based on the data type, and determine an initial data transmission strategy corresponding to the test data to be analyzed based on the transmission priority and the first network state data, wherein the network state data comprises at least one of network delay, packet loss rate and bandwidth utilization rate.

[0056] The transmission priority can be understood as a strategy level of setting different transmission priority levels according to the importance and urgency of the test data to be analyzed. The first network state data can be understood as historical network state data.

[0057] Specifically, the transmission strategy determination module obtains network state data in real time from a network monitoring system or a network state data source, including key indicators such as network delay, packet loss rate and bandwidth utilization. For each test data to be transmitted, identify its data type, such as binary files, etc. Different data types have different requirements for network performance, so the transmission strategy needs to be formulated according to the data type. Based on the data type and business requirements, each test data to be analyzed will be assigned a transmission priority. The priority may be determined based on factors such as data real-time, importance, file size, and user requests. Combined with the transmission priority and the first network state data, an initial data transmission strategy is formulated. The initial data transmission strategy includes transmission rate adjustment, data compression use, transmission protocol selection, data segmentation and parallel transmission, etc.

[0058] In the embodiments of the present application, by dynamically adjusting the transmission strategy, network resources are more effectively utilized, ensuring the priority transmission of critical data, while reducing network congestion and bandwidth waste. By selecting appropriate transmission rate, compression method and transmission protocol, the delay and bandwidth occupancy of data transmission can be reduced, and the overall efficiency of data transmission can be improved.

[0059] Optionally, the system further comprises a transmission strategy adjustment module, wherein,

[0060] The transmission strategy adjustment module is configured to obtain second network state data, and adjust the initial data transmission strategy based on the second network state data to obtain a target data transmission strategy corresponding to the test data to be analyzed.

[0061] The second network state data can be understood as real-time network state data. The target data transmission strategy can be understood as the adjusted data transmission strategy.

[0062] Specifically, according to the real-time situation of network bandwidth, the rate of data transmission is dynamically adjusted to avoid network congestion and data loss. According to the size of the data packet and the network delay situation, it is determined whether to split the data into smaller data packets for transmission to reduce the packet loss rate and improve the transmission efficiency. When data packet loss occurs, the retransmission strategy is adjusted according to the real-time state of the network, such as the number of retransmissions, the retransmission interval, etc., to ensure the integrity of the data. According to the urgency and importance of the data, different transmission priorities are set for different data packets to ensure that critical data can be transmitted in priority.

[0063] In the embodiment of the present application, by comprehensively considering real-time network state data and initial data transmission strategy, the transmission strategy adjustment module can generate a target data transmission strategy corresponding to the test data to be analyzed. The optimization of data transmission in the current network environment helps to improve the efficiency and reliability of data transmission, and reduce the risk of network congestion and data loss.

[0064] The technical scheme of the embodiment of the present application, through the transmission strategy determination unit, acquires the first network state data, determines the data type of each test data to be analyzed, determines the transmission priority corresponding to the test data to be analyzed based on the data type, and determines the initial data transmission strategy corresponding to the test data to be analyzed based on the transmission priority and the first network state data. Through the transmission strategy determination unit, the first network state data is acquired, and the data type, transmission priority and initial data transmission strategy of each test data to be analyzed are determined, which can optimize the data transmission efficiency, improve the network resource utilization rate, and enhance the reliability and stability of data transmission.
