[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] Before engaging or disengaging the voltage plates inside the substation protection panel, voltage measurements are required. However, to determine if the voltage value is correct, it needs to be compared with the standard value. Only after verification can the voltage plate be engaged. Typically, different protection models, different circuits, and different switch states will cause variations in the standard value, which is difficult for operators to remember.

[0025] The existing technology involves printing all standard values ​​and posting them inside the cabinet, then manually checking the interval status on-site and finding the corresponding standard value in the standard value table for verification. However, because there are many pressure plates in the cabinet, this method requires manual comparison with the table for each voltage measurement, resulting in low efficiency in substation pressure plate potential detection. Furthermore, since each verification requires changing the original operating position, it may lead to the incorrect pressure plate being put in after verification. In addition, there is the problem that standard values ​​may change dynamically, and the posted values ​​cannot be updated in time. Moreover, if the posted tables for some cabinets are damaged or fall off, the data on which the verification is based will be lost during the operation.

[0026] To address the aforementioned issues, this application provides relevant solutions, which are detailed below.

[0027] According to an embodiment of this application, a method for detecting the voltage of a substation pressure plate is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0028] The method embodiments of this application can be operated in a smart voltmeter. In the above operating environment, the embodiments of this application provide a substation voltage detection method. Figure 1 This is a schematic diagram of a method for detecting the voltage of a substation pressure plate according to an embodiment of this application, as shown below. Figure 1 As shown, the method includes the following steps:

[0029] Step S102: In response to the first voice command, determine the identification information corresponding to the pressure plate to be tested. The first voice command is triggered when the target button of the smart voltmeter is pressed and then released. When the target button is in the pressed state, the smart voltmeter is used to collect voice data, and the voice data is used to generate the first voice command.

[0030] Step S104: Determine the preset voltage values ​​corresponding to the upper and lower terminals of the pressure plate under test based on the identification information of the pressure plate under test.

[0031] Step S106: Obtain the actual voltage values ​​corresponding to the upper and lower terminals of the pressure plate to be tested, and compare the actual voltage values ​​with the preset voltage values;

[0032] Step S108: If the difference between the actual voltage value and the preset voltage value exceeds the preset ratio threshold, a voltage alarm message is sent. The voltage alarm message is used to indicate that there is an abnormality in the voltage of the test plate.

[0033] Through the above steps, the current pressure plate is located by intelligent voice input, and the preset standard voltage value corresponding to the pressure plate is automatically obtained and compared with the current measured voltage value. This achieves the goal of improving the detection efficiency of pressure plates in substations, and solves the technical problem of low detection efficiency of pressure plate potential in substations caused by the need for manual comparison with tables and standard values ​​for each voltage measurement in related technologies.

[0034] The substation pressure plate potential detection method in steps S102 to S108 of the embodiments of this application will be further described below.

[0035] In this embodiment, the smart voltmeter includes: two voice input buttons (i.e., the target button), one reset button, two probe ports, and an AC / DC switching button, which can be used to measure DC or AC voltage. The meter dial menu includes information such as the substation used, smart measurement, ordinary measurement, and voltage plate potentiometer library.

[0036] The target button can be located on the side of the meter and includes a first button and a second button, which correspond to the closed and open positions of the interval switch, respectively. When pressed, voice input is performed. That is, when the first voice command is triggered by the first button, it indicates that the interval switch corresponding to the pressure plate under test is in the closed state, and when the first voice command is triggered by the second button, it indicates that the interval switch corresponding to the pressure plate under test is in the open state.

[0037] Before each substation voltage test, you can first select the substation to use on the meter, and then input the subsequent information via voice using the target button, as follows.

[0038] When the operator performs the voice input, the cabinet name can be extracted. For example, if the voice input is "22P 110kV training line 1210 line protection panel", the key information (cabinet identifier) ​​can be extracted and displayed on the voltmeter as: Cabinet number: 22P, Cabinet name: 110kV training line 1210 line protection panel. Simultaneously, the pressure plate double number (pressure plate identifier) ​​can also be extracted. For example, if the voice input is "Measure the ground potential at both ends of the 1LP1 protection outlet pressure plate, normal", the voltmeter will display: Pressure plate number: 1LP1, Pressure plate name: Protection outlet pressure plate.

[0039] In addition, the status of the interval switch can be obtained by pressing the button when the operator makes a voice input.

[0040] After extracting the identification information from the input voice data through speech recognition, the fuzzy algorithm can be used to correctly select the device in the library based on the identified identification information, obtain the preset voltage value corresponding to the pressure plate, and display it on the dial. The specific steps are as follows.

[0041] In some embodiments of this application, the identification information includes: cabinet identification, pressure plate identification, and interval switch status, wherein the interval switch status includes: closed state and open state; determining the preset voltage values ​​corresponding to the upper and lower terminals of the pressure plate under test based on the identification information corresponding to the pressure plate under test includes the following steps: identifying the cabinet identification and pressure plate identification in the voice data collected by the smart voltmeter, wherein the cabinet identification includes: cabinet number and cabinet name, and the pressure plate identification includes: pressure plate number and pressure plate name; obtaining the preset voltage values ​​of the upper and lower terminals corresponding to the cabinet identification, pressure plate identification, and interval switch status in the database corresponding to the substation where the pressure plate under test is located, wherein the database includes multiple data items, each data item being used to characterize the preset voltage values ​​of the upper and lower terminals corresponding to a pressure plate of a cabinet in a certain interval switch status; and sending the identified cabinet identification, pressure plate identification, interval switch status, and preset voltage values ​​to the display interface of the smart voltmeter for display.

[0042] Specifically, in this embodiment, an Excel spreadsheet of voltage meters at the upper and lower ends of each pressure plate of each station and each cabinet can be prepared in advance and transmitted to the meter via computer to form a voltage meter library (i.e., the aforementioned database) as a retention criterion.

[0043] In addition, in this embodiment, the preset voltage values ​​corresponding to the upper and lower terminals of each pressure plate in the database can also be viewed or modified by a smart voltmeter. The specific steps are as follows.

[0044] In some embodiments of this application, the method further includes the following steps: in response to a data query instruction, obtaining data items from the database according to the filtering conditions in the data query instruction, and sending the data items to the display interface of the smart voltmeter for display; in response to a data modification instruction, updating the preset voltage values ​​of the upper and lower terminals corresponding to the data items in the database; in response to an overall update instruction, updating all data items in the file corresponding to the overall update instruction to the database of the smart voltmeter, wherein each data item is used to characterize the preset voltage values ​​of the upper and lower terminals corresponding to a pressure plate of a cabinet in a certain interval switch state.

[0045] To avoid errors in pronunciation or speech recognition during vote counting, as an optional implementation, the method further includes the following steps: obtaining the cabinet name corresponding to the cabinet number in the database, and sending a first alarm message if the cabinet name stored in the database is inconsistent with the cabinet name obtained by speech recognition, wherein the first alarm message indicates that the cabinet number or cabinet name is entered incorrectly; if the cabinet name stored in the database is consistent with the cabinet name obtained by speech recognition, determining whether the pressure plate number obtained by speech recognition exists in the pressure plate data corresponding to the cabinet number in the database, and sending a second alarm message if the pressure plate number obtained by speech recognition does not exist in the pressure plate data, wherein the second alarm message indicates that the pressure plate number does not correspond to the cabinet number; if the pressure plate number obtained by speech recognition exists in the pressure plate data, obtaining the pressure plate name corresponding to the pressure plate number in the database, and sending a third alarm message if the pressure plate name stored in the database is inconsistent with the pressure plate name obtained by speech recognition, wherein the third alarm message indicates that the pressure plate number or pressure plate name is entered incorrectly.

[0046] After obtaining the preset voltage values ​​corresponding to the upper and lower terminals of the pressure plate under test, the actual voltage values ​​corresponding to the upper and lower terminals of the pressure plate under test can be obtained, and the actual voltage values ​​can be compared with the preset voltage values. The specific steps are as follows.

[0047] In some embodiments of this application, comparing the actual voltage value with a preset voltage value includes the following steps: in response to a second voice command, obtaining the actual voltage value corresponding to the upper terminal of the pressure plate under test, and determining the deviation ratio between the actual voltage value corresponding to the upper terminal and the preset voltage value corresponding to the upper terminal; if the deviation ratio is greater than a preset ratio threshold, sending a first voltage alarm message, wherein the first voltage alarm message is used to indicate that the voltage of the upper terminal of the pressure plate under test is abnormal; in response to a third voice command, obtaining the actual voltage value corresponding to the lower terminal of the pressure plate under test, and determining the deviation ratio between the actual voltage value corresponding to the lower terminal and the preset voltage value corresponding to the lower terminal; if the deviation ratio is greater than a preset ratio threshold, sending a second voltage alarm message, wherein the second voltage alarm message is used to indicate that the voltage of the lower terminal of the pressure plate under test is abnormal.

[0048] Specifically, the operator can voice input: "Measure the upper voltage" (i.e., the second voice command mentioned above). Then, the preset voltage value of the upper terminal and the measured actual voltage value of the upper terminal will be compared. If the difference is within the preset percentage threshold (taking 20% ​​as an example), it will be reported as normal; otherwise, it will be reported as abnormal and a first voltage alarm message will be sent. And, the operator can voice input: "Measure the lower and upper voltages" (i.e., the third voice command mentioned above). Then, the preset voltage value of the lower terminal and the measured actual voltage value of the lower terminal will be compared. If the difference is within the preset percentage threshold (taking 20% ​​as an example), it will be reported as normal; otherwise, it will be reported as abnormal and a second voltage alarm message will be sent.

[0049] The actual voltage values ​​and preset voltage values ​​obtained from the upper and lower terminals of the pressure plate under test can be displayed in the format shown in the table below:

[0050]

[0051] In addition, it is necessary to detect the polarity of the voltages between the upper and lower terminals. The specific steps are as follows.

[0052] In some embodiments of this application, after obtaining the actual voltage value corresponding to the lower terminal of the pressure plate under test, the method further includes: determining whether the polarity of the actual voltage value corresponding to the upper terminal of the pressure plate under test is the same as the polarity of the actual voltage value corresponding to the lower terminal; if the polarities are different, sending a third voltage alarm message, wherein the third voltage alarm message is used to characterize the presence of an abnormal polarity in the pressure plate under test.

[0053] Specifically, the upper and lower measured values ​​are compared to determine whether there is polarity. If there is, an anomaly is determined and a third voltage alarm message is sent. In this embodiment, the actual voltage value of the lower terminal can be automatically compared with the preset voltage value of the lower terminal and the actual voltage value measured at the upper terminal each time the actual voltage value of the lower terminal is measured.
