[0033] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Please see the attached Figure 1 and attached Figure 2 The embodiment of the present invention provides a method for detecting water leakage at the spindle center of a direct-drive swing head, comprising the following steps:

[0035] S1. Sensor placement: Sensors are set at different locations inside the water outlet channel;

[0036] S2, data monitoring and recording: add timestamps to the sensor's collected data and store the data in the database;

[0037] S3. Dynamic real-time monitoring: When the direct-drive swing head is running, infrared thermal imaging equipment is used to monitor the temperature distribution at the water outlet in real time;

[0038] S4. Data processing and judgment: Compare the sensor data with the normal working threshold to determine whether it exceeds the normal threshold range, and determine the water leakage location based on the temperature distribution at the water outlet;

[0039] S5. Online alarm and feedback: When a water leakage is detected and reaches the preset alarm threshold, the system immediately sends an online alarm signal and generates a report with the sensor data recorded with the timestamps before and after the alarm occurs.

[0040] Specifically, S1 can achieve real-time and accurate monitoring of physical parameters in the water outlet channel by arranging sensors in the water outlet channel. Sensors at different locations can fully capture changes in the channel, and can detect possible water outlet leakage problems in the early stages of equipment operation. This reduces the limitations and errors of single-position detection and greatly improves the accuracy and reliability of detection, thereby buying valuable time for taking preventive and repair measures, avoiding equipment damage and production interruptions caused by undetected leakage problems, and ensuring the stable operation of the direct-drive swing head spindle center water outlet system.

[0041] S2 adds precise time stamps to the collected sensor data, which can reflect the chronological order of data generation and facilitate subsequent data analysis and tracing. At the same time, these time-stamped data are stored in the database, achieving effective management and preservation of large amounts of data and reducing the risk of decision-making errors caused by data loss or confusion.

[0042] In the S3, infrared thermal imaging equipment is used to continuously monitor the temperature distribution at the water outlet. Real-time detection ensures immediate understanding of the equipment's operating status, enabling problems to be discovered as soon as they occur, preventing further deterioration of potential faults. The intuitive presentation of temperature distribution helps pinpoint abnormal areas, shortening troubleshooting time and reducing downtime losses caused by faults. This improves the safety and stability of equipment operation and ensures production continuity and efficiency.

[0043] By comparing data with preset normal operating thresholds, S4 can identify abnormal situations and promptly discover potential problems. At the same time, combined with infrared thermal imaging equipment to comprehensively judge the temperature distribution at the water outlet, it can more accurately locate the specific location of water leaks, thereby improving the accuracy and reliability of judgments, preventing problems from escalating, and ensuring the stable and efficient operation of the spindle center water outlet system of the direct-drive swing head.

[0044] The sensors in S5 can promptly issue warnings to relevant personnel when they detect that water leakage has reached a dangerous level, making it easy to take quick measures to deal with the water leakage problem and avoid more serious consequences caused by the leakage. They also generate sensor data reports containing timestamp records, providing detailed and accurate basis for subsequent fault analysis and processing, minimizing the losses that may be caused by leakage, improving the efficiency and accuracy of problem handling, and enhancing the safety and reliability of the entire direct-drive swing head water outlet system.

[0045] The sensors include a flow sensor, a pressure sensor and a humidity sensor. The flow sensor is used to detect changes in water flow, the pressure sensor is used to detect changes in pressure in the water outlet channel, and the humidity sensor is used to detect changes in humidity in the channel.

[0046] Specifically, the flow sensor can detect changes in water flow and sensitively perceive abnormal fluctuations in water flow, which helps to detect possible blockages or leakages; the pressure sensor is used to detect pressure changes in the water outlet channel, which can promptly reflect changes in resistance inside the channel and effectively warn of pipe damage or blockage; the humidity sensor detects changes in humidity in the channel and can capture abnormal increases in moisture, thereby accurately detecting early signs of leakage. The sensor groups cooperate with each other to achieve all-round and high-precision monitoring of the water outlet channel, ensuring the stable operation of the system, reducing the risk of failures, and improving the reliability and safety of the equipment.

[0047] In S2, the corresponding detection data is extracted by searching the database for the timestamp.

[0048] Specifically, by retrieving the corresponding test data from the database based on timestamps, data from a specific time point or time period can be quickly and accurately located within a large amount of test data, thereby improving the efficiency and accuracy of subsequent data analysis, helping to identify problems more promptly and summarize water leakage patterns. This provides strong support for optimizing equipment operation, predicting potential failures, and formulating maintenance strategies, thereby improving the performance and reliability of the entire system.

[0049] Dynamic real-time monitoring includes the following steps:

[0050] S31: Use infrared thermal imaging equipment to scan and photograph the water outlet location;

[0051] S32: Receive infrared rays emitted by the object through the infrared detector and convert them into electrical signals;

[0052] S33: Through image processing and analysis, the electrical signal is converted into a visible thermal image.

[0053] Specifically, the S31 uses infrared thermal imaging equipment to scan and capture temperature changes at the water outlet in real time, ensuring that no possible abnormal areas are missed. This provides rich raw data for subsequent analysis, ensuring continuity and completeness in monitoring the water outlet, and facilitating early detection of potential problems.

[0054] In S32, infrared rays are converted into electrical signals for subsequent processing, laying the foundation for subsequent image processing and analysis;

[0055] In S33, the electrical signal is processed to generate an intuitive and visible thermal image, thus presenting the complex electrical signal in the form of an intuitive and easy-to-understand thermal image, allowing operators to easily identify abnormal temperature areas and make quick judgments and decisions, thereby improving the efficiency and accuracy of monitoring;

[0056] In S4, the threshold range for normal operation of the direct-drive swing head is set based on the standard of the water outlet system of the direct-drive swing head spindle center.

[0057] Specifically, the threshold range for normal operation is set based on the standards of the direct-drive swing head spindle center water outlet system, which provides a clear reference basis for judging the operating status of the system. By establishing these thresholds, it is possible to distinguish between the parameter range during normal system operation and the range where abnormalities or failures may occur, thereby conducting targeted monitoring and analysis.

[0058] When the humidity sensor detects an abnormal increase in the humidity in the channel location area in S4, the infrared thermal imaging device is used to detect the temperature distribution of the area and its surroundings.

[0059] Specifically, when the humidity sensor detects an abnormal increase in humidity in the channel location area, the infrared thermal imaging equipment will use the initial abnormal humidity indication to start a more accurate temperature distribution detection in a targeted manner, which can more accurately locate the possible leakage location, avoiding the waste of resources and inefficiency caused by indiscriminate temperature detection of the entire channel, improving the targetedness and accuracy of the detection, and being able to more quickly and effectively detect potential leakage problems, reducing the time and cost of troubleshooting, ensuring the stable operation of the direct-drive swing head spindle center water outlet system, and reducing the risk of equipment damage and production accidents caused by failure to detect leaks in time.

[0060] Online alarm signals in S5 include but are not limited to mobile devices and fixed monitoring terminals, and the report includes sensor data with timestamps from 2 minutes before the alarm to 0 to 2 minutes after the alarm;

[0061] Specifically, online alarm signals covering mobile devices and fixed monitoring terminals are designed to ensure that alarm information can be conveyed to relevant personnel through multiple channels and in an all-round manner. Regardless of whether they are on-site through fixed monitoring terminals or at other locations through mobile devices, they can receive water leakage alarms in a timely manner, shortening the time interval from alarm to action, and effectively reducing the losses and risks that may be caused by delayed response. Including sensor data with timestamps for specific time periods before and after the alarm in the report can provide key time series data for analyzing the development process and severity of water leakage, helping technicians analyze the evolution process of the fault and providing quantitative data support for evaluating the overall performance and stability of the system.

[0063] Sensor module: used to install the sensor group in the water outlet channel;

[0064] Data acquisition and recording module: used to add timestamps to the data collected by the sensor and store it in the database

[0068] Specifically, the sensor module installs a sensor group in the water outlet channel to achieve comprehensive monitoring of key locations. The data acquisition and recording module adds timestamps to the collected data and stores it in the database, ensuring the integrity and traceability of the data. The infrared thermal imaging monitoring module detects the temperature of the water outlet in real time and can keenly capture temperature anomalies. The data processing and judgment module accurately judges water leakage and location by comparing thresholds and analyzing temperature distribution, thereby improving the accuracy and reliability of detection. The alarm and feedback module sends a signal and generates a report in time when the alarm threshold is reached, enabling relevant personnel to respond quickly and take measures, effectively reducing losses caused by leakage and ensuring the stable operation of the system and the safety of production.
