Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0027] Figure 2 A schematic flow chart of a method for monitoring the quality of pole flange connections provided in one embodiment of the present application. DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] In an exemplary embodiment, Figure 1 As shown, a pole flange connection quality monitoring system is provided, including a pressure sensor 102 and a data processing device 103.

[0031] The data processing device 103 may be, but is not limited to, various desktop computers, laptop computers, smart phones, tablet computers, IoT devices, and portable wearable devices. The IoT devices may be smart speakers, smart TVs, etc. The portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc.

[0032] The pressure sensor 102 is installed at the connection of the pole flange 101 to be tested and connected to the data processing device 103. The pressure sensor 102 is used to collect the pressure value during the connection process of the pole flange 101 to be tested in real time and send the pressure value to the data processing device 103 in real time.

[0033] The pressure value is expressed in standard units (such as Pascal), and the pressure value collected by the pressure sensor 102 represents the pressure applied at the connection of the pole flange 101 to be tested. Each pressure value is associated with a timestamp, indicating the exact time when the pressure value was collected, and the timestamp can be accurate to milliseconds to ensure that the time series is correctly sorted.

[0034] In an exemplary embodiment, the pressure sensor 102 is connected to the data processing device 103 via wired or wireless communication.

[0035] The pressure sensor 102 is mounted on the outer surface of the connection contact surface of the pole flange 101 to be tested.

[0036] There are multiple pressure sensors 102 ; the multiple pressure sensors 102 are respectively installed at different positions of the connection of the pole flange 101 to be tested, so as to collect the pressure values ​​of different positions during the connection process of the pole flange 101 to be tested in real time.

[0037] The data processing device 103 is used to generate a pressure variation curve according to the received pressure value, and monitor the connection quality of the pole flange 101 to be tested in real time according to the pressure variation curve.

[0038] Specifically, the data processing device 103 continuously monitors the output of the pressure sensor 102 to ensure that all pressure changes during the connection process are captured. The monitoring frequency can be adjusted as needed, usually in units of several times per second.

[0039] The data processing device 103 displays the real-time measured pressure value on a monitor so that relevant personnel can understand the pressure change during the connection process at any time, usually in a graphical form, such as a curve chart of pressure change.

[0040] In an exemplary embodiment, the data processing device 103 determines the connection stability of the pole flange 101 to be tested according to the fluctuation of the pressure change curve to determine the connection quality of the pole flange 101 to be tested. A stable connection should be manifested as a small pressure fluctuation and a stable stage of longer duration. By analyzing the amplitude of the pressure value in the pressure change curve, it is determined whether the connection has reached the expected tightness. Too low pressure may indicate a loose connection, while too high pressure may cause the connection to be overstressed. If there are abnormal fluctuations or mutations in the pressure change curve, there may be loose connection, unevenness or other problems, which require further inspection and adjustment.

[0041] The data processing device 103 is also used to determine whether the pressure at different parts of the pole flange 101 to be tested is uniform according to the pressure values ​​at different parts during the connection process of the pole flange 101 to be tested, so as to determine the connection quality of the pole flange 101 to be tested. Uneven pressure distribution may indicate that the connection of the pole flange 101 to be tested is offset or asymmetric, and further adjustment or calibration is required.

[0042] The data processing device 103 is also used to determine in real time whether the pressure value during the connection process of the pole flange 101 to be tested is greater than the preset pressure threshold, and to trigger an alarm when the pressure value during the connection process of the pole flange 101 to be tested is greater than the preset pressure threshold, and to diagnose the cause of the alarm to prompt relevant personnel to take response measures in time. Specifically, an alarm condition can be set during the monitoring process, and an alarm is triggered when the pressure value exceeds the preset pressure threshold to help relevant personnel to promptly discover potential problems and take measures. Take appropriate measures according to the severity and frequency of the alarm, including stopping the connection process, adjusting the connection parameters, or conducting further inspections and maintenance. Further diagnose the pressure changes when the alarm occurs to determine the possible causes, which may involve checking the position, tightening condition, environmental conditions and other factors of the connecting components.

[0043] The data processing device 103 is also used to store the pressure value during the connection process of the pole flange 101 to be tested in a database and / or export it to an external storage device. All real-time monitored pressure values ​​and related information are recorded, including connection stability, pressure changes, alarm processing, etc., for subsequent analysis and review. The recorded data can be stored in the database of the data processing device 103 or exported to an external file for future reference and analysis.

[0044] The data processing device 103 is also used to calibrate the pressure sensor 102 and obtain the status information of the pressure sensor 102 in real time. That is, the status information of the pressure sensor 102 itself, such as connection status, battery power, sensor failure, etc., is recorded in real time and displayed on a display to help determine the reliability of the pressure value and the working status of the pressure sensor 102.

[0045] Based on the same inventive concept, Figure 2 As shown, the embodiment of the present application further provides a pole flange connection quality monitoring method based on the pole flange connection quality monitoring system involved above, comprising the following steps 201 to 203.

[0046] Step 201 , installing a pressure sensor 102 at the connection of the pole flange 101 to be tested, and establishing a communication link between the pressure sensor 102 and the data processing device 103 .

[0047] In an exemplary embodiment, the process of installing the pressure sensor 102 is as follows:

[0048] (1) Determine the installation position: Carefully select a suitable position at the connection of the pole flange 101 to be tested to install the pressure sensor 102. The pressure sensor 102 is usually installed near the connection contact surface of the pole flange 101 to be tested to ensure that the pressure change can be accurately measured.

[0049] (2) Prepare installation equipment: Prepare the equipment and tools required for installation, including screwdrivers, wrenches, fasteners, etc. Make sure these equipment are clean to avoid contaminating the pressure sensor 102 or connecting parts.

[0050] (3) Clean the installation area: Clean the work area around the installation location to ensure that there is no debris or dirt. Use an appropriate cleaning agent to wipe the connection surface of the pole flange 101 to be tested to ensure that the pressure sensor 102 can fully fit and accurately measure the pressure.

[0051] (4) Install the pressure sensor 102: Gently place or fix the pressure sensor 102 at the selected position. According to the model and design of the pressure sensor 102, use screws to fix the pressure sensor 102 to the connecting outer surface of the pole flange 101 to be tested, ensuring that the installation fasteners will not damage the pressure sensor 102 or the connecting parts, and the pressure sensor 102 is in a stable position.

[0052] (5) Connecting the pressure sensor 102: Connect the power line or signal line of the pressure sensor 102 according to the instructions or instructions of the pressure sensor 102, and ensure that the connection is correct and firm so that the pressure sensor 102 can work normally and transmit data.

[0053] (6) Test installation: After installation, perform a simple test to ensure that the pressure sensor 102 is correctly installed and working properly. Check whether the pressure sensor 102 is firmly fixed on the pole flange 101 to be tested and whether it can accurately measure pressure changes.

[0054] (7) Record installation details: Record the location, fixing method, connection method and any other important details of the pressure sensor 102. These records will help with future maintenance and troubleshooting.

[0055] Step 202 , collecting the pressure value of the pole flange 101 to be tested during connection in real time through the pressure sensor 102 , and sending the pressure value to the data processing device 103 in real time.

[0056] Step 203: Generate a pressure variation curve according to the received pressure value by the data processing device 103, and monitor the connection quality of the pole flange 101 to be tested in real time according to the pressure variation curve.

[0057] In an exemplary embodiment, the pole flange connection quality monitoring method further includes step 204 .

[0058] Step 204, determining in real time through the data processing device 103 whether the pressure value during the connection process of the pole flange 101 to be tested is greater than the preset pressure threshold, triggering an alarm when the pressure value during the connection process of the pole flange 101 to be tested is greater than the preset pressure threshold, and diagnosing the cause of the alarm to prompt relevant personnel to take response measures in time.

[0059] The present application first installs a pressure sensor 102 at the connection of the pole flange 101 to be tested. Then, the pressure sensor 102 and the data processing device 103 are operated to monitor the pressure changes during the connection process of the pole flange 101 to be tested in real time. Then, according to the real-time monitored pressure changes, the connection quality of the pole flange 101 to be tested is evaluated by computer algorithm or manually. Finally, necessary measures are taken according to the evaluation results to improve the connection quality of the pole flange 101 to be tested.

[0060] In an exemplary embodiment, the operation process of the data processing device 103 is as follows:

[0061] (1) Device startup: Start the data processing device 103 and ensure that it is operating normally. This may involve starting a computer or dedicated data processing device 103 and verifying that the device software and hardware are in normal working order.

[0062] (2) Calibration of the pressure sensor 102: Before running the data processing device 103, the pressure sensor 102 is calibrated to ensure that the pressure sensor 102 can accurately measure the pressure value. The calibration process may include connecting the pressure sensor 102 to a calibration device with a known pressure value and adjusting the settings of the pressure sensor 102 to ensure its accuracy.

[0063] (3) Setting parameters: Setting parameters in the data processing device 103, such as sampling frequency, data storage format, etc. These parameters will affect how the system records and stores pressure data, as well as the subsequent data processing method.

[0064] (4) Start data collection: Once the data processing device 103 is set up, start data collection. The data processing device 103 will start to monitor the output of the pressure sensor 102 in real time and record the pressure value. The collected data can be a continuous time series or can be triggered according to preset conditions.

[0065] (5) Data processing and analysis: During the data acquisition process, the data will be transferred to a computer or monitoring device for processing and analysis. Data processing may include operations such as filtering, denoising, or data compression to prepare the data for further analysis. The data is then analyzed using specialized software or algorithms to extract useful information, such as the trend and magnitude of pressure changes.

[0066] (6) Real-time monitoring and feedback: During the data collection and processing process, the data processing device 103 can monitor the pressure changes in real time and provide real-time feedback based on preset thresholds or conditions, so that relevant personnel can understand the status of the pole flange connection process at any time and take necessary measures in a timely manner.

[0067] (7) Data storage and reporting: After data collection is completed, the data will be stored in the data processing device 103 or exported to an external storage device. These data can be used to generate reports or analysis to provide relevant personnel with connection quality assessment information to evaluate the quality of the connection of the pole flange 101 to be tested. The report may include connection quality assessment results, pressure change charts, problem diagnosis results, recommended improvement measures and other information for subsequent recording and analysis.

[0068] This application is used in the acceptance stage of pole flanges at the factory. A connection test is carried out when the pole flanges are not put into formal use. Advanced sensor technology and data acquisition systems are used to monitor the pressure changes during the pole flange connection process in real time, thereby evaluating the connection quality of the pole flanges. This makes the test process simpler and more efficient, and the test results more reliable and accurate, to ensure the stability and safety of the pole flanges in actual applications, which is of great significance to improving the reliability and safety of the power transmission system.
