[0055] In addition, the “plurality” mentioned in the embodiments of the present application should be interpreted as two or more.

[0056] With the idea of ​​improving the testing efficiency of relay protection devices, reducing labor costs, and improving testing accuracy, the inventors have discovered that the test voice can be recognized to obtain the test content, and when the test content is complete, the first model and test action of the relay protection device under test can be determined according to the test content and a preset test case library. Afterwards, when it is determined that the relay protection device test device is correctly connected to the relay protection device under test, the relay protection device under test is tested based on the first model and the test action. In this way, based on the test voice and the preset test case library, automatic testing of the relay protection device under test can be achieved, which improves the testing efficiency and accuracy of the relay protection device, while freeing up manpower and reducing labor costs.

[0057] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0058] First reference Figure 1 , Figure 1 An application scenario of the present application is schematically shown, wherein the application scenario includes a connected relay protection device testing device 101 and a relay protection device 102 to be tested.

[0059] The relay protection device testing device 101 obtains the test voice, inputs the test voice into the trained speech recognition model, obtains the test content, and when it is determined that the test content is complete, determines the first model and test action of the relay protection device under test according to the test content and the preset test case library, and then detects whether it itself is correctly connected to the relay protection device 102 under test. If it is detected that it is correctly connected to the relay protection device 102 under test, the relay protection device under test is tested based on the first model and the test action.

[0060] Combine the following Figure 1 ,refer to Figure 2To describe a relay protection device testing method provided according to an exemplary embodiment of the present application.

[0061] Figure 2 FIG. 1 is a flow chart of a relay protection device testing method provided in an embodiment of the present application. Figure 2 As shown, the method in the embodiment of the present application may include:

[0062] Step 201: Acquire test speech, input the test speech into the trained speech recognition model, and obtain test content.

[0063] In this embodiment, the test voice may be the voice issued by the tester to test the relay protection device under test, for example, the test voice may be "perform PCS-931 line I section protection check of manufacturer A", and the test voice needs to include the manufacturer and device model of the relay protection device under test, so as to clarify the relay protection device under test, and include the protection stage and test items, so as to clarify which test needs to be performed on the relay protection device under test. The test voice of the tester may be obtained by using a microphone or other sound receiving device.

[0064] Exemplarily, the speech recognition model may include an acoustic model and a language model. Among them, the acoustic model inputs the test speech (sound signal) emitted by the tester, parses the sound signal, and outputs a computer-recognizable code. The language model inputs the code corresponding to the sound signal, performs semantic recognition on the code, and outputs the recognized semantic content (i.e., test content). The language model may be a neural network model such as a deep neural network (DNN), a convolutional neural network (CNN), or a recurrent neural network (RNN). The trained speech recognition model is trained based on different test speech samples and test content samples.

[0065] In a possible implementation, before inputting the test voice into the trained speech recognition model to obtain the test content, the present embodiment may also obtain different test voice samples and corresponding test content samples, form a training set with the different test voice samples and the corresponding test content samples, and train the preset speech recognition model based on the training set to obtain a trained speech recognition model.

[0066] Among them, the preset relay protection test professional corpus includes test speech samples and corresponding test content samples. The speech recognition model can be trained based on the preset relay protection test professional corpus to obtain a speech recognition model with good performance.

[0067] Optionally, the test content may include multiple of the manufacturer, device model, protection stage, test items and combination items. The test items include protection type and protection principle, and / or, protection type and protection item. Among them, the manufacturer may include "Manufacturer A", "Manufacturer B" and "Manufacturer C", etc., and the device model may include "PCS-931" and "CSC-281", etc. The relay protection device to be tested can be determined based on the manufacturer and device model. The protection stage may include "Section I", "Section II" and "Section III", etc., indicating the stage at which the relay protection device to be tested needs to be tested.

[0068] Protection types may include "line protection", "busbar protection", "main transformer protection", "circuit breaker protection", "lead protection" and "high-voltage protection", etc., which are used to indicate the type of test that needs to be performed on the relay protection device under test from one dimension. Protection principles may include "longitudinal differential protection", "distance protection", "zero-sequence protection", "overcurrent protection", "re-pressure lockout", "single-phase / three-phase reclosing", etc., which are used to indicate the type of test that needs to be performed on the relay protection device under test from another dimension. Protection items may include "loop check", "setting verification", "protection verification", "network test", "whole group test" and "communication debugging", etc., which are used to indicate the type of test that needs to be performed on the relay protection device under test from another dimension.

[0069] A combination project can include two or more test items, that is, a combination project is a flexible combination of test items, so that the tester only needs to output a simple test voice to perform multiple tests on the relay protection device under test. For example, the test item "longitudinal differential protection of line protection" and the test item "zero sequence protection of line protection" are combined into a combination project and named "line protection configuration test item 1". In this way, the combination project can include "line protection configuration test item 1", etc. The naming of each combination project and the test items included can be pre-set by relevant personnel according to needs.

[0070] It should be noted that, for the test items, the type of test to be performed on the relay protection device under test can be determined based on the protection type and protection principle, or the type of test to be performed on the relay protection device under test can be determined based on the protection type and protection items.

[0071] For example, for the test voice "Perform protection check of PCS-931 line section I of manufacturer A", after being recognized by the voice recognition model, the test content "Manufacturer A (manufacturer)", "Line (protection type)", "PCS-931 (device model)", "Section I (protection stage)" and "Protection check (protection item)" can be obtained. It should be noted that when the trained voice recognition model recognizes the test voice, it can perform keyword recognition. For example, for the "line" in the test voice, the voice recognition model can recognize "line (protection type)" based on "line".

[0072] Step 202: determine whether the test content is complete, and when it is determined that the test content is complete, determine the first model and test action of the relay protection device under test according to the test content and a preset test case library.

[0073] In this embodiment, after the test content is identified, it is first determined whether the test content is complete. If the test content is complete, the steps of determining the first model and test action of the relay protection device under test according to the test content and the preset test case library are executed. If the test content is incomplete, an alarm prompt of incomplete test content is issued to enable the tester to determine the reason for the incomplete test content. If it is determined that the test content is incomplete due to lack of content in the test voice, the tester re-issues the test voice. If it is determined that the test content is incomplete due to the inability of the speech recognition model to recognize it, the tester will split the test voice according to "manufacturer", "device model" and "test item", etc., and add the split corpus and the corresponding test voice to the relay protection test professional corpus, so that the speech recognition model can be better trained in subsequent training.

[0074] In some embodiments, when determining whether the test content is complete, the test content may be determined to be complete when the test content includes the manufacturer, device model, and protection stage, and the test content also includes at least one of a test item and a combination item.

[0075] Exemplarily, from the foregoing, when the test content includes the manufacturer and device model, the relay protection device under test can be determined; when the test content includes the protection stage and test items, and / or includes the protection stage and combined items, it can be determined which type of test is performed on the relay protection device under test.

[0076] In some embodiments, when it is determined that the test content is complete, determining the first model and test action of the relay protection device under test according to the test content and a preset test case library may include steps S1 to S4.

[0077] S1. When it is determined that the test content is complete, determine the first model of the relay protection device to be tested based on the manufacturer and device model.

[0078] S2. If the test content includes test items, and the test items include protection types and protection principles, the test action is determined according to the protection stage, protection type and protection principle, and the first test case in the preset first test case library; the first test case indicates the correspondence between the protection stage, protection type, protection principle and test action.

[0079] S3. If the test content includes test items, and the test items include protection types and protection items, the test action is determined according to the protection stage, protection type and protection items, as well as the second test case in the preset second test case library; the second test case indicates the correspondence between the protection stage, protection type, protection items and test action.

[0080] S4. If the test content includes a combination item, a test action is determined according to the combination item and a third test case in a preset third test case library; the third test case indicates a corresponding relationship between the combination item and a plurality of test actions.

[0081] From the above, it can be seen that according to the manufacturer and device model in the test content, the relay protection device under test can be determined, that is, the first model of the relay protection device under test can be determined. For example, according to the test content including "Manufacturer A" and "PCS-931", the first model of the relay protection device under test is determined to be "Manufacturer A PCS-931".

[0082] Exemplarily, a plurality of first test cases in the preset first test case library are used to indicate the corresponding relationship between the protection stage, the protection type, the protection principle and the test action, wherein the test action is the action performed when the relay protection device under test is tested. According to the protection stage in the test content, the protection type and protection principle included in the test item, and the first test case, the corresponding test action can be determined.

[0083] Optionally, multiple second test cases in the preset second test case library are used to indicate the corresponding relationship between the protection stage, protection type, protection item and test action. According to the protection stage in the test content, the protection type and protection item included in the test item, and the second test case, the corresponding test action can be determined.

[0084] Exemplarily, the plurality of third test cases in the preset third test case library are used to indicate the correspondence between the combination project and the plurality of test actions. Here, since the combination project can generally include two or more test projects, the combination project corresponds to the plurality of test actions. If the test content includes the combination project, the plurality of test actions can be determined according to the combination project and the third test case.

[0085] After that, after determining the first model and the test action, the corresponding relay protection device under test can be tested.

[0086] Step 203: Detect whether the relay protection device test device is correctly connected to the relay protection device under test. If the relay protection device test device is correctly connected to the relay protection device under test, test the relay protection device under test based on the first model and the test action.

[0087] In this embodiment, after determining the first model and test action, it is possible to first detect whether the relay protection device test device and the relay protection device under test are correctly connected to prevent voltage short circuit and / or current open circuit phenomena, which may cause the relay protection device test device and the relay protection device under test to fail to be electrically connected, and thus make it impossible to subsequently test the relay protection device under test.

[0088] In some embodiments, when detecting whether a relay protection device test device is correctly connected to the relay protection device under test, test information can be sent to the relay protection device under test. If feedback information returned by the relay protection device under test is received within a preset time period, it is determined that the relay protection device test device is correctly connected to the relay protection device under test.

[0089] Optionally, if no feedback information is received from the relay protection device under test within a preset time period, it is determined that the relay protection device test device is not correctly connected to the relay protection device under test. At this time, an alarm is issued to allow the staff to reconnect the relay protection device test device and the relay protection device under test.

[0090] In this embodiment, the preset time period can be set as needed.

[0091] In a possible implementation, before testing the relay protection device under test based on the first model and the test action, the present embodiment may also obtain the second model of the relay protection device under test. Accordingly, when testing the relay protection device under test based on the first model and the test action, it may be determined whether the first model is consistent with the second model. If the first model is consistent with the second model, an excitation amount is applied to the relay protection device under test based on the test action, wherein the test action indicates the corresponding excitation amount.

[0092] Exemplarily, in order to further detect whether the relay protection device under test connected to the relay protection device test device is the "relay protection device under test" indicated in the test content, this embodiment can first obtain the second model of the relay protection device under test connected to the relay protection device test device, for example, read the second model. Afterwards, if the first model is consistent with the second model, it indicates that the relay protection device under test connected to the relay protection device test device is the "relay protection device under test" indicated in the test content, and there is no connection error. At this time, the excitation amount is applied to the relay protection device under test based on the test action.

[0093] The excitation quantity may be a test voltage, a test current and / or a switch quantity, etc., which is applied to the relay protection device under test by the relay protection device test device to implement the test of the relay protection device under test. For example, according to the test action, a test current is applied to the relay protection device for a preset test time.

[0094] Exemplarily, the test voice may also include two tests on the relay protection device under test. For example, if the test voice is "perform protection verification and overcurrent protection of PCS-931 line section I of manufacturer A", the test content is identified to include "manufacturer A (manufacturer)", "line (protection type)", "PCS-931 (device model)", "section I (protection stage)", "protection verification (protection item)" and "overcurrent protection (protection principle)". Subsequently, one test action may be determined based on the protection stage in the test content, the protection type and protection principle included in the test item, and the first test case, and another test action may be determined based on the protection stage in the test content, the protection type and protection item included in the test item, and the second test case. In this way, there is one first model and two test actions, that is, the test content actually includes two separate and complete test items.

[0095] In some embodiments, when there is one first model and there are at least two test actions, when applying an excitation amount to the relay protection device under test based on the test action, corresponding excitation amounts can be applied to the relay protection device under test in sequence based on each test action.

[0096] Optionally, when there is one first model and at least two test actions, the relay protection device under test can be tested in steps.

[0097] Optionally, after the relay protection device under test is tested, test feedback data may be obtained, so as to determine whether the relay protection device under test has passed the test based on the test feedback data.

[0098] In some embodiments, before testing the relay protection device under test based on the first model and the test action, configuration data of the relay protection device under test can also be obtained. Correspondingly, after testing the relay protection device under test based on the first model and the test action, test feedback data can also be obtained, and the test result can be determined according to the test feedback data and the configuration data, wherein the test result includes a test pass and a test fail.

[0099] In this embodiment, the configuration data may be the fixed value data of the relay protection device under test, etc. The test result is determined based on the acquired test feedback data and fixed value data, etc. For example, if the fixed value data is 4A, the test is passed if it is greater than 4A, and the acquired test feedback data is 5A, then the test result is determined to be passed. Among them, the relay protection device test device can communicate with the substation background system through the TCP (Transmission Control Protocol) protocol, and this embodiment can obtain the test feedback data of the relay protection device under test from the substation background system.

[0100] Optionally, the test results can be broadcasted using a speaker or other sound playback device so that the tester can know the test results. For example, the voice broadcast content can be "Manufacturer A PCS-931 line I section protection verification is correct, the test passed" etc.

[0101] The relay protection device testing method provided in the embodiment of the present application utilizes a trained speech recognition model to recognize the test speech emitted by the tester to obtain the test content, and when the test content is complete, the first model and the test action of the relay protection device under test are determined according to the test content and the preset test case library. Afterwards, when it is determined that the relay protection device testing device is correctly connected to the relay protection device under test, the relay protection device under test is tested based on the first model and the test action. In this way, based on the test speech, the trained speech recognition model and the preset test case library, automatic testing of the relay protection device under test can be achieved, which improves the testing efficiency and accuracy of the relay protection device, while freeing up manpower and reducing labor costs.

Among them, the automatic test module can be connected to the relay protection device under test through a cable or an optical cable, and can be connected to the substation background system through the TCP protocol.

The voice input module can be a microphone or other sound receiving device, which is used to obtain the test voice of the tester and send the test voice to the voice recognition module.

[0106] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
