[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] In one exemplary embodiment, such as Figure 1 As shown, a testing device for instruments in a valve cooling system is provided, including an instrument testing unit 100, a test cable 200, and a display unit 300;

[0032] At least one end of the test cable 200 includes a connector 201 that mates with the interface terminal of the valve cooling system instrument.

[0033] The test cable 200 is connected to the interface terminal through the connector 201, and the test signal of the instrument under test is transmitted to the instrument test unit 100 through the test cable 200.

[0034] The valve cooling system refers to a system used for cooling the converter valve, comprising multiple valve cooling system instruments responsible for real-time monitoring of the converter valve's operating status and other key parameters. Test cable 200 is used to connect the valve cooling system instruments to the instrument testing unit 100. For example... Figure 2 As shown, the connector 201 of the test cable 200 is matched with the interface terminal of the valve cooling system and is used to connect to the interface terminal of the valve cooling system. The interface terminal can establish a connection with the valve cooling system instrument, thereby transmitting the test signal of the valve cooling system instrument from the interface terminal to the instrument test unit 100 for analysis through the connector 201.

[0035] For example, once the test cable 200 is successfully connected to the interface terminal of the valve cooling system via connector 201, the transmission of test signals from the valve cooling system instruments will begin. These test signals may include current, voltage, or other signal formats, depending on the configuration of the valve cooling system and the testing requirements. The test signals are stably transmitted to the instrument testing unit 100 via connector 201.

[0036] Exemplarily, the test cable 200 can be connected to the valve cooling system instrument via a direct connection or a connection through a connector 201. In one optional embodiment, the test cable 200 is connected to the instrument under test via the connector 201, thereby transmitting the test signal of the valve cooling system instrument and performing testing on the instrument without reconfiguring the test cable 200. In another optional embodiment, the test cable 200 is directly connected to a measuring instrument, thereby transmitting the test signal of the valve cooling system instrument and performing testing on the instrument even when the measuring instrument is not connected to the valve cooling system.

[0037] The instrument testing unit 100 is used to analyze the test signal, obtain the instrument test result, and send the instrument test result to the display unit 300.

[0038] The instrument testing unit 100 is an integrated signal analysis and processing module that can receive test signals from the test cable 200 and analyze and process them. Optionally, the instrument testing unit 100 can detect the signal status, determine the current connection status of the instrument under test, and determine whether the instrument under test is connected to the valve cooling system. The instrument test results may include the instrument's operating status, abnormal information of the test signal, or other diagnostic information related to system operation.

[0039] For example, after the test signal is transmitted to the instrument testing unit 100 via the test cable 200, the instrument testing unit 100 begins to analyze the signal and generate corresponding instrument test results. Specifically, the instrument testing unit 100 extracts useful information from the test signal through methods such as decoding, signal filtering, and numerical calculation. Optionally, the instrument testing unit 100 can verify the test signal according to a preset standard to determine whether the test signal is within a predetermined operating range. If the signal exceeds the predetermined range, the instrument testing unit 100 will mark the test signal as abnormal. After processing the test signal and generating the instrument test results, the instrument testing unit 100 sends the instrument test results to the display unit 300 through the communication interface.

[0040] Display unit 300 is used to visualize the instrument test results.

[0041] The display unit 300 can be a device for receiving and displaying the processing results from the instrument testing unit 100. It is responsible for converting the data and results analyzed by the instrument testing unit 100 into graphics, text, or warning information that is easy for operators to understand and interpret. In some embodiments, the display unit 300 is equipped with a display screen, which can be a touchscreen or other form of visualization device.

[0042] For example, after receiving the instrument test results, the display unit 300 will convert and process the instrument test results.

[0043] Optionally, for numerical results, the display unit 300 converts them into a format suitable for display, which can be displayed as a table or chart through a graphical interface; for waveforms of test signals, the display unit 300 displays waveform diagrams or trend charts.

[0044] Optionally, the display unit 300 is equipped with a touchscreen, allowing operators to interact with it to view more detailed test data or adjust display parameters. For example, operators can zoom in on the data waveform over a specific time period or select to display different types of measurement results.

[0045] In this embodiment, the test cable 200 is connected to the interface terminal of the valve cooling system via connector 201, enabling rapid access to test signals and shortening the test circuit setup time. Simultaneously, the high-quality design of connector 201 ensures stable signal transmission, preventing data loss or errors caused by poor contact or loose cables, thus ensuring signal accuracy and reliability. The instrument testing unit 100 can analyze signals in real time and quickly generate instrument test results, ensuring timely feedback of various monitoring data from the valve cooling system. Furthermore, the test results are visualized through the display unit 300, allowing operators to intuitively understand the system's real-time operating status, thereby improving the efficiency of instrument testing for the valve cooling system.

[0046] In an exemplary embodiment, there are multiple test cables 200; each of the multiple test cables 200 is connected to multiple instruments under test, and is used to transmit the test signals corresponding to the multiple instruments under test to the instrument test unit 100; the instrument test unit 100 is used to compare the multiple test signals to obtain the instrument data comparison result, and send the instrument data comparison result to the display unit 300; the display unit 300 is used to visualize the instrument data comparison result as the instrument test result.

[0047] Specifically, multiple test cables 200 are connected to multiple instruments under test (DUTs) via connectors 201. The DUTs can be backup instruments, and the selection of backup instruments ensures that in the event of a failure of an online instrument, it can be promptly replaced and the operating status of the valve cooling system can continue to be monitored. Each test cable 200 is connected to a different backup instrument and transmits its corresponding test signal to the instrument test unit 100.

[0048] After receiving test signals from multiple backup instruments, the instrument testing unit 100 compares these signals. The testing unit analyzes each test signal and calculates the data differences, generating instrument data comparison results. By comparing the signals from backup instruments with those from other instruments, operators can determine whether the backup instruments are functioning correctly and whether they can replace faulty instruments, ensuring the system's normal operation after instrument replacement. The instrument testing unit 100 sends the data comparison results to the display unit 300, which presents the instrument data comparison results to the operator in a visual format.

[0049] In this embodiment, by using multiple test cables 200 to connect multiple backup instruments, real-time monitoring and signal detection of the backup instruments can be achieved. The instrument testing unit 100 can quickly detect anomalies in the backup instruments by comparing data from multiple test signals, and the visualization provided by the display unit 300 improves the efficiency of fault diagnosis.

[0050] In one exemplary embodiment, the device includes an integrated housing that integrates an instrument testing unit 100, multiple test cables 200, and a display unit 300 within the same housing.

[0051] In this embodiment, the instrument testing unit 100, multiple test cables 200, and display unit 300 are all installed in an integrated housing. The integrated housing design not only improves the portability of the equipment but also reduces the connection complexity caused by the dispersed components. The entire testing process, from signal analysis by the instrument testing unit 100 to data display by the display unit 300, can be completed by carrying only one housing.

[0052] In an exemplary embodiment, the display unit 300 includes an instrument range control. The instrument test unit 100 is configured to convert the instrument test result according to the range set by the instrument range control, obtain the converted instrument test result, and send the instrument test result to the instrument range control. The instrument range control is configured to visualize the converted instrument test result according to the range.

[0053] For example, the operator sets the desired range using the instrument range control on the display unit 300. This range control can be provided in the form of a numeric input box, a slider, or a preset button, allowing the operator to flexibly adjust the range in different testing scenarios. After the range is set using the instrument range control, the instrument testing unit 100 performs range conversion on the received test signal based on these range parameters. For example, if the set range is a larger or smaller range, the instrument testing unit 100 will automatically adjust the original test results to the new range range to ensure that the test results meet the requirements of the selected range. After the instrument testing unit 100 completes the range conversion, the display unit 300 will visually display the converted test results.

[0054] In this embodiment, the instrument testing unit 100 automatically switches according to the range to ensure that the test results are always within the correct range, thereby improving the adaptability of the equipment. The adjustability of the range control and the real-time update mechanism of the display unit 300 enable operators to quickly adjust and obtain test results during the testing process, thus improving operational efficiency.

[0055] In an exemplary embodiment, the instrument testing unit 100 is used to perform real-time analysis of the test signal and send the instrument test results to the display unit 300 while the test cable 200 remains connected to the instrument under test; the display unit 300 is used to visualize and record the real-time analyzed instrument test results.

[0056] Specifically, during the testing process, the test cable 200 maintains a connection with the instrument under test. This continuous connection allows the instrument testing unit 100 to perform real-time analysis of the test signals, whether during preliminary testing or monitoring. During real-time analysis, the instrument testing unit 100 verifies, filters, and calculates the test signals using signal processing algorithms to generate instrument test results. After completing the signal analysis, the instrument testing unit 100 transmits the real-time analyzed instrument test results to the display unit 300. Upon receiving the instrument test results, the display unit 300 prepares for visualization. Simultaneously, the display unit 300 also records the test results for the corresponding time period to ensure data integrity and historical tracking. The recorded data can be viewed, analyzed, and archived by operators later.

[0057] In this embodiment, the instrument testing unit 100 analyzes the signal and generates test results in real time, ensuring the consistency and accuracy of the data during the test; the display unit 300 visualizes the test results, updates them in real time, and records the updated data, thereby enhancing the reliability of the test and the traceability of the data, and improving the test efficiency.

[0058] In one example embodiment, the display unit 300 includes an ammeter; the ammeter is used to display the instrument test results or to display the current signal value of the test signal.

[0059] Optionally, the test signal is transmitted from the instrument under test (DUT) to the instrument test unit 100 via the test cable 200. During this process, a current signal is transmitted to the instrument test unit 100 as part of the test signal. The current signal can represent the workload or state change of a certain part of the valve cooling system. The instrument test unit 100 analyzes the received current signal and generates a current analysis result. The ammeter in the display unit 300 displays the current analysis result in the form of numbers, graphs, or indicator dials.

[0060] In some embodiments, the ammeter of the display unit 300 can display the current signal value of the test signal to determine the connection status of the instrument test unit 100.

[0061] In this embodiment, the current analysis results or the current value of the test signal are visualized by the ammeter of the display unit 300, which enables the operator to quickly understand the data and improves the operating efficiency.

[0062] In one exemplary embodiment, the display unit 300 includes a warning control; the display unit 300 is configured to highlight the warning control when the instrument test result indicates that the current instrument is in an abnormal state.

[0063] Specifically, test signals are transmitted to the instrument testing unit 100 via test cable 200. The instrument testing unit 100 analyzes these signals in real time and generates test results for the instrument. If the instrument test results show that the signal exceeds the normal range or other abnormalities exist, the testing unit will mark the instrument as being in an abnormal state. When the instrument testing unit 100 detects that the instrument is in an abnormal state (e.g., excessive current, excessive voltage fluctuations), it will immediately trigger a warning mechanism. The warning mechanism alerts the operator to the abnormal state of the instrument by activating a warning control in the display unit 300. After an abnormal state is detected, the warning control will be highlighted in the display unit 300. The display method may include changing the background or font color of the display unit 300 to red to highlight the abnormal instrument state.

[0064] In this embodiment, the display unit 300 provides clear visual prompts to operators when an anomaly occurs by promptly displaying warning controls. This enables anomalies to be detected and addressed in the first instance, thereby improving the efficiency of fault response.

[0065] In one exemplary embodiment, the device includes a device power acquisition interface.

[0066] Specifically, such as Figure 2 As shown, the test device is equipped with a power acquisition interface (L, N), which can be connected to an external current source. This interface provides the power required by the device to ensure the normal operation of the test power supply 101.

[0067] In this embodiment, the device can obtain a stable power supply through an external power connection interface, ensuring the stable operation of the test power supply 101.

[0068] In an exemplary embodiment, the instrument testing unit 100 includes a test power supply 101; the test power supply 101 is used to form a test current loop when the device is connected to the instrument under test.

[0069] Specifically, such as Figure 2 As shown, when the device is connected to the instrument under test (DUT), the test power supply 101 starts working, providing the necessary current to the DUT. The DUT and the various units of the test device form a test current loop. Once the loop is successfully established, the instrument test unit 100 can stably receive the test signal from the DUT and begin analyzing it. Optionally, the output current of the test power supply 101 is adjusted by the instrument test unit 100 according to the requirements of the DUT to ensure that the current is suitable for the current measurement conditions.

[0070] In this embodiment, the current loop provided by the test power supply 101 ensures the accurate transmission of the instrument's test signal. A stable current supply avoids signal fluctuations, guarantees data accuracy, and thus improves the reliability of the test results.

[0071] In an exemplary embodiment, the instrument testing unit 100 includes a data conversion unit 102; the data conversion unit 102 is used to convert the data format of the test signal.

[0072] In one example, such as Figure 3 As shown, the input interface of the data conversion unit 102 in the testing device is identified by AI+, and the output interface is represented by AI-. Optionally, the test signal of the instrument under test is input by AI+, which converts the analog form of the data into digital form, and outputs it to other modules through AI-.

[0073] Specifically, the test signal is transmitted to the instrument testing unit 100 via the test cable 200. The data conversion unit 102 of the instrument testing unit 100 first receives the test signal and prepares to convert it. The data conversion unit 102 converts the received test signal into a data format suitable for further analysis and processing. This process includes, but is not limited to, encoding conversion, unit conversion, and format standardization of the test signal. After the data conversion unit 102 completes the data conversion, the converted signal can be transmitted to other processing modules of the instrument testing unit 100.

[0074] In this embodiment, by converting the data format of the test signal, compatibility between different signal forms can be achieved, ensuring that the system can process signal data from different types of instruments, and ensuring the accuracy and reliability of the test signal.

[0075] To enable those skilled in the art to better understand the above-described apparatus, the following example illustrates the embodiments of this application, but it should be understood that the embodiments of this application are not limited thereto.

[0076] In one exemplary embodiment, a testing device for valve-cooled system instruments includes multiple test cables 200, a display unit 300, an instrument testing unit 100, and a device power acquisition interface. The multiple test cables 200, display unit 300, instrument testing unit 100, and device power acquisition interface are integrated into a... Figure 4 The integrated housing shown includes: a test cable 200 with a connector 201 that matches the interface segment of the valve cooling system; a display unit 300 with an ammeter, a range control, and a warning control; and an instrument testing unit 100 with a data conversion unit 102 and a test power supply 101. When the instrument under test is not connected to the valve cooling system, the above-described testing device for valve cooling system instruments can be configured to perform the following steps:

[0077] A stable power supply is obtained from the device's power acquisition interface to the test power supply 101. The test power supply 101 forms a current loop to provide the necessary current to the instrument under test, ensuring the accuracy of the test signal. The test current loop ensures stable current flow, avoiding unstable test results due to current fluctuations.

[0078] Multiple test cables 200 are connected to the instrument under test (DUT). Each test cable 200 is matched with the interface terminal of the valve cooling system via a connector 201 to ensure a stable connection. Each test cable 200 is connected to a different DUT, and these instruments can be backup instruments.

[0079] The test signal transmitted by the instrument under test is transmitted to the instrument test unit 100 via the test cable 200. The test signal can be in the form of current, voltage, etc. The instrument test unit 100 transmits the received signal to the data conversion unit 102 for processing. The data conversion unit 102 converts the data format of the test signal into a data format suitable for subsequent processing.

[0080] The instrument testing unit 100 performs real-time analysis of the test signals from the instrument under test after data conversion and processing. When multiple instruments are tested simultaneously, the instrument testing unit 100 compares multiple test signals and generates instrument data comparison results. By comparing signals from different instruments laterally, the testing unit can detect any anomalies, helping to determine whether there are faults or other problems in the valve cooling system.

[0081] The display unit 300 includes an instrument range control, which allows the operator to set the range of the test signal. The instrument testing unit 100 will perform range conversion on the test signal according to the set range to ensure that the test results are within the set range, thereby guaranteeing the accuracy and consistency of the test data.

[0082] The display unit 300 visualizes the instrument test results, presenting them in the form of charts, numbers, etc., and records the results for subsequent data analysis and report generation. If the instrument test results indicate an abnormality (e.g., current exceeding the normal range), the display unit 300 will highlight a warning message through a warning control to alert the operator to the abnormal state of the instrument. The warning control can be displayed using methods such as red highlighting, flashing icons, or pop-up warning boxes.

[0083] In an exemplary embodiment, a test process is provided for a test apparatus applied to a valve cooling system instrument as described above. In this embodiment, the process includes the following steps:

[0084] The test device receives test signals from the instrument under test (DUT) via test cable 200. Test cable 200 is connected to the interface terminals via connector 201 that matches the interface terminals of the valve cooling system. Exemplarily, the test device connects to the DUT via test cable 200 and receives test signals from the DUT via test cable 200, providing basic data for subsequent signal analysis. Test signals include, but are not limited to, current and voltage signals, determined by the operating state of the DUT.

[0085] The test signal is analyzed to obtain the instrument test result. For example, when the test signal is transmitted to the test device via test cable 200, the test device analyzes the received signal in real time. The test device decodes, filters, and processes the signal according to a preset algorithm or standard, identifies valid data in the test signal, eliminates interference, and finally obtains the instrument test result, which reflects the working status of the instrument under test.

[0086] The instrument test results are visualized. For example, the instrument test results are visualized using a testing device. Specifically, the testing device presents the analyzed instrument test results in the form of graphics, numbers, or charts to help operators intuitively understand the test results.

[0087] In this embodiment, the testing device can quickly receive and analyze test signals from the instrument under test, quickly establish a connection with the instrument signal loop of the valve cooling system, shorten the test loop setup time, and realize visualized signal loop diagnosis and data reading, thereby improving testing efficiency.

[0088] In an exemplary embodiment, a test process is provided for the test apparatus for the instrument used in the valve cooling system described above. In this embodiment, the test process includes: analyzing the connection status of the test signal to obtain an instrument test result indicating the connection status of the instrument under test; the connection status includes whether the instrument under test is connected to the valve cooling system and whether the instrument under test is not connected to the valve cooling system; when the instrument under test is connected to the valve cooling system, the signal loop switch of the valve cooling system indicates that the switch is closed; when the instrument under test is not connected to the valve cooling system, the signal loop switch of the valve cooling system indicates that the switch is open.

[0089] For example, the testing device receives the test signal from the instrument under test (DUT) via test cable 200. The testing device performs preliminary analysis of the test signal to identify its connection status, thereby obtaining the corresponding instrument test result. Based on the instrument test result, the testing device determines the connection status of the DUT. Figure 2 As shown, if the test signal comes from an instrument connected to the valve cooling system, the testing device will detect that the switch state of the signal loop is closed, i.e., switches S1 and S2 are closed; if the test signal comes from an instrument not connected to the valve cooling system, the testing device will detect that the switch state of the signal loop is open, i.e., switches S1 and S2 are open. Based on the analysis of the connection status, the testing device generates instrument test results, which are displayed visually to help operators understand the instrument's connection status and signal transmission.

[0090] In this embodiment, through the above steps, the instrument under test no longer needs to be connected to the valve cooling system before testing. The testing device can directly perform circuit loop testing on the instrument under test, thus improving the testing efficiency.

[0091] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least a portion of the steps or stages of other steps.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.
