[0002] Laser processing equipment is a device that uses a high-power-density laser beam to process materials, and it is widely used in manufacturing, electronics, medical, and other fields. During operation, laser processing equipment generates a significant amount of heat; if this heat is not dissipated in a timely manner, it may lead to equipment damage or a decrease in processing accuracy. Therefore, the cooling system of laser processing equipment is particularly important.

[0003] However, the cooling system itself can also malfunction. In related technologies, manual inspection and handling are carried out after the cooling system malfunctions. This is not only time-consuming and labor-intensive, but also requires the laser processing equipment to be shut down for inspection, resulting in high overall costs. Summary of the Invention

[0004] Therefore, it is necessary to provide a cooling system anomaly monitoring method, device, computer equipment, computer-readable storage medium, and computer program product that can reduce the cost of cooling system anomaly monitoring in response to the above-mentioned technical problems.

[0005] In a first aspect, this application provides a method for monitoring abnormalities in a cooling system, wherein the cooling system is applied to laser processing equipment, and the method includes:

[0006] The operating status of the cooling system is verified when the laser processing equipment is in the startup preparation stage;

[0007] Under the condition that the operation status of the cooling system has been verified and the laser processing equipment is in the laser processing stage, the medium monitoring data is acquired and verified. The medium monitoring data is collected from at least one monitoring point in the cooling system.

[0008] If at least one medium monitoring data fails verification, the failed medium monitoring data is identified as abnormal medium monitoring data. Based on the abnormal medium monitoring data and the monitoring points corresponding to the abnormal detection data, the anomaly of the cooling system is located.

[0009] In one embodiment, the operating status includes system start / stop status and pipeline flow status; verifying the operating status of the cooling system includes:

[0025] Obtain the difference between the outlet medium temperature and the inlet medium temperature, and determine the difference as the medium temperature rise value;

[0026] Check whether the temperature rise of the detection medium exceeds the preset temperature rise limit.

[0027] In one embodiment, the method further includes:

[0028] After the cooling system is initialized, the cooling circuit flow direction of each cooling module in the laser processing equipment is verified.

[0029] If the cooling circuit flow direction verification of at least one cooling module fails, the cooling module that fails the verification is identified as a circuit abnormal cooling module, and a circuit abnormal alarm is output. The circuit abnormal alarm is used to prompt the switching of the circuit input terminal and the circuit output terminal corresponding to the circuit abnormal cooling module.

[0030] Secondly, this application also provides a cooling system anomaly monitoring device, wherein the cooling system is applied to laser processing equipment, and the device includes:

[0031] The first verification module is used to verify the operating status of the cooling system when the laser processing equipment is in the power-on preparation stage.

[0032] The second verification module is used to acquire and verify the medium monitoring data when the cooling system's operating status verification is passed and the laser processing equipment is in the laser processing stage. The medium monitoring data is collected from at least one monitoring point in the cooling system.

[0033] The positioning module is used to identify the failed medium monitoring data as abnormal medium monitoring data when at least one medium monitoring data fails verification, and to locate the abnormality of the cooling system based on the abnormal medium monitoring data and the monitoring point corresponding to the abnormal detection data.

[0034] Thirdly, this application also provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to perform the following steps:

[0035] The operating status of the cooling system is verified when the laser processing equipment is in the startup preparation stage;

[0036] Under the condition that the operation status of the cooling system has been verified and the laser processing equipment is in the laser processing stage, the medium monitoring data is acquired and verified. The medium monitoring data is collected from at least one monitoring point in the cooling system.

[0037] If at least one medium monitoring data fails verification, the failed medium monitoring data is identified as abnormal medium monitoring data. Based on the abnormal medium monitoring data and the monitoring points corresponding to the abnormal detection data, the anomaly of the cooling system is located.

[0038] Fourthly, this application also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, performs the following steps:

[0039] The operating status of the cooling system is verified when the laser processing equipment is in the startup preparation stage;

The medium monitoring data is collected from at least one monitoring point in the cooling system.

[0041] If at least one medium monitoring data fails verification, the failed medium monitoring data is identified as abnormal medium monitoring data. Based on the abnormal medium monitoring data and the monitoring points corresponding to the abnormal detection data, the anomaly of the cooling system is located.

[0042] Fifthly, this application also provides a computer program product, including a computer program that, when executed by a processor, performs the following steps:

[0046] The aforementioned cooling system anomaly monitoring method, apparatus, computer equipment, computer-readable storage medium, and computer program product refer to a cooling system applied to laser processing equipment. First, while the laser processing equipment is in the startup preparation phase, the operating status of the cooling system is verified to ensure its normal operation during laser processing. Then, after the cooling system's operating status verification is passed and the laser processing equipment is in the laser processing phase, medium monitoring data is acquired and verified. The medium monitoring data is collected from at least one monitoring point in the cooling system. During laser processing, the cooling requirements of the laser processing equipment are high. The cooling system's performance is fully demonstrated. During this process, the collection and verification of media monitoring data improves the effectiveness of the verification. Then, if at least one media monitoring data fails verification, it is identified as abnormal media monitoring data. Based on the abnormal media monitoring data and the corresponding monitoring points, the cooling system is located for anomalies. This achieves synchronous anomaly monitoring of the cooling system during laser processing. If an anomaly exists, it can be accurately and promptly captured and located. If no anomaly is found, the cooling system ensures the normal operation of the laser processing equipment, thus avoiding resource waste and ensuring uninterrupted operation. In this way, while ensuring accurate and timely capture and location of cooling system anomalies, the cost of anomaly monitoring for cooling systems used in laser processing equipment is effectively reduced.

[0053] 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.

[0054] In one exemplary embodiment, such as Figure 1 As shown, a method for monitoring cooling system anomalies is provided. This embodiment illustrates the application of this method to a terminal, where the terminal can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, projection devices, etc. Portable wearable devices can include smartwatches, smart bracelets, head-mounted devices, etc. Head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. It is understood that this method can also be applied to servers, and can also be applied to systems including terminals and servers, and implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps S10-S30.

[0055] In this embodiment, the method includes the following steps S10-S30. Wherein:

[0056] Step S10: When the laser processing equipment is in the power-on preparation stage, verify the operating status of the cooling system.

[0057] A cooling system refers to a device or system used to remove heat generated by laser processing equipment during operation. During laser processing, the high-energy-density laser beam interacts with the material, and the laser itself, along with other optical components, can generate significant heat due to continuous energy conversion. If this heat is not removed in time, it can lead to decreased laser performance, shortened lifespan, or even equipment damage. Cooling methods can include at least one of liquid cooling, air cooling, and thermoelectric cooling. The cooling system can operate synchronously with the laser processing equipment to remove the heat generated during operation. If the cooling system malfunctions and fails to provide timely cooling, heat accumulation in the laser processing equipment can occur, potentially leading to decreased laser performance, shortened lifespan, or even equipment damage. Therefore, monitoring the cooling system for abnormalities is also a way to protect the laser processing equipment.

[0058] The startup preparation phase can refer to the period of time between starting up the laser processing equipment and the start of formal processing. During the startup preparation phase, the laser processing equipment can perform at least one of the following preparatory activities: startup detection, equipment self-test, optical path calibration, parameter setting, preheating, and trial operation.

[0059] The operating status of a cooling system can refer to the state of the cooling system and its various functional modules, as well as the series of functions and activities performed to maintain a suitable operating temperature. The operating status of a cooling system can include at least one of the following: the start / stop status of the cooling system, and the operating status of each functional module within the cooling system.

[0060] For example, the cooling system can be started synchronously with the laser processing equipment. Then, while the laser processing equipment is preparing, the cooling system can also perform its own preparation activities. These preparation activities include at least verifying the cooling system's operating status, and may also include at least one of the following: power-on detection, equipment self-test, and parameter settings. Passing the cooling system's operating status verification indicates that the cooling system is functioning normally and has begun operation; failing the verification indicates that the cooling system is not functioning normally or has not yet begun operation.

[0061] During the startup preparation phase of laser processing equipment, the operating status of the cooling system is simultaneously verified. Firstly, this ensures the cooling system is functioning correctly and operational before the laser processing equipment begins operation. This avoids situations where an overheating alarm occurs after the laser processing equipment has started, only to discover later that the cooling system is not running or malfunctioning. This improves the synchronization between the cooling system and the laser processing equipment, reduces the likelihood of the equipment shutting down due to overheating, and enhances the cooling system's heat dissipation effect, thereby improving the processing stability of the laser processing equipment. Secondly, since the operating status of the cooling system typically remains unchanged during the laser processing phase, verifying its operation before the laser processing equipment starts eliminates the need for further verification should any abnormalities occur. This reduces the monitoring burden on the cooling system during the laser processing phase, effectively saving resources.

[0062] Step S20: When the cooling system's operating status verification is passed and the laser processing equipment is in the laser processing stage, acquire medium monitoring data and verify the medium monitoring data. The medium monitoring data is collected from at least one monitoring point in the cooling system.

[0063] The laser processing stage can refer to the time period after the start-up preparation activities are completed, during which the laser processing equipment performs laser processing operations such as cutting, welding, marking, and engraving on the material according to the preset parameters and paths.

[0064] Cooling medium refers to the substance used in a cooling system to absorb and transfer heat. Its main function is to remove heat from the heat source and transfer it to the environment, thereby maintaining the operating temperature of the laser processing equipment within a safe range. Medium monitoring data refers to data obtained by monitoring the temperature, flow rate, pressure, and other parameters of the cooling medium in the cooling system.

[0065] For example, if the cooling system passes the operation status verification, the cooling system can send a verification pass message to the laser processing equipment. After the laser processing equipment completes the start-up preparation activities and receives the verification pass message from the cooling system, it can start to enter the laser processing stage and perform laser processing operations on the material. After determining that the laser processing equipment has entered the laser processing stage, the cooling system can collect medium monitoring data of the cooling medium at regular intervals or in real time through sensors deployed at various monitoring points, and verify the collected medium monitoring data at regular intervals or in real time.

[0066] If the cooling system's operational status verification fails, the system can automatically attempt to change its operating status. For example, if the cooling system is detected to be stopped, it can be turned on; if a valve in the cooling system is detected to be closed, that valve can be opened. The system then returns to the steps of verifying its operational status until the verification passes or the number of cycles reaches a preset threshold. If the verification still fails after reaching the preset threshold, an operational status anomaly alarm can be triggered to alert relevant personnel to address the anomaly in the cooling system's operational status promptly.

[0067] In some feasible implementations, the method of verifying the media monitoring data may include: comparing the media monitoring data with a preset threshold; if there is media monitoring data exceeding the preset threshold, the verification is deemed to have failed; if there is no media monitoring data exceeding the preset threshold, the verification is deemed to have passed.

[0068] In other feasible embodiments, the verification of media monitoring data may also include: inputting the media monitoring data into a preset anomaly monitoring model, determining whether the media monitoring data verification passes through the preset anomaly monitoring model, and outputting the verification result. The anomaly detection model can be a statistical model, a neural network model, etc., and can be determined according to actual needs; this embodiment does not impose any limitations on this.

[0069] Step S30: If at least one medium monitoring data fails verification, the failed medium monitoring data is identified as abnormal medium monitoring data. Based on the abnormal medium monitoring data and the monitoring points corresponding to the abnormal detection data, the abnormality of the cooling system is located.

[0070] For example, if one or more media monitoring data fail verification, the failed media monitoring data is identified as abnormal media monitoring data. Then, the monitoring sites where abnormal media monitoring data was detected are queried. Based on each abnormal media monitoring data and its corresponding monitoring site, the anomaly of the cooling system is located. For instance, if the temperature of the cooling medium at a certain monitoring site is found to be too high, the anomaly can be located within a section of pipeline before and after that monitoring site, so that relevant personnel can quickly troubleshoot and handle the anomaly based on the anomaly location. If the temperature and pressure of the cooling medium at a certain monitoring site are both too high, it may be due to a blockage in the downstream section causing heat and water pressure to accumulate at that monitoring site. Therefore, the anomaly can be located within a section of pipeline after that monitoring site, so that relevant personnel can quickly troubleshoot and handle the anomaly based on the anomaly location.

[0071] If all media monitoring data passes verification, it indicates that there is no abnormality in the current cooling system. Therefore, there is no need to locate the abnormality or issue an alarm, and the monitoring of the cooling system can continue.

[0072] In some feasible implementations, an anomaly alarm can be triggered if at least one medium monitoring data verification fails, prompting relevant personnel to promptly investigate and handle the anomaly. After anomaly localization, the anomaly localization results can be generated and displayed to facilitate rapid anomaly investigation and handling by relevant personnel. It is understood that anomaly alarms and anomaly localization can be performed simultaneously, or anomaly localization can be performed first followed by anomaly alarms. Since it may take some time for relevant personnel to discover an anomaly alarm, the simultaneous approach of anomaly alarm and anomaly localization can alert relevant personnel to the existence of an anomaly as early as possible. By the time relevant personnel actually conduct anomaly investigation and handling, anomaly localization is usually also complete, thus providing information for anomaly localization and investigation.

[0073] In the aforementioned cooling system anomaly monitoring method, the cooling system refers to the cooling system applied to the laser processing equipment. First, while the laser processing equipment is in the startup preparation phase, the operating status of the cooling system is verified to ensure its normal operation during laser processing. Then, after the cooling system's operating status verification is passed and the laser processing equipment is in the laser processing phase, medium monitoring data is acquired and verified. This medium monitoring data is collected from at least one monitoring point within the cooling system. During laser processing, the laser processing equipment has high cooling requirements, and the various performance characteristics of the cooling system are fully demonstrated. During this process, the collection and verification of medium monitoring data can improve the effectiveness of the verification. Then, if at least one medium monitoring data fails verification, the failed data is identified as abnormal. Based on the abnormal monitoring data and the corresponding monitoring points, the cooling system is located for anomalies. This achieves synchronous anomaly monitoring of the cooling system during laser processing. If an anomaly is found, it can be accurately and promptly captured and located. If no anomaly is found, the cooling system ensures the normal operation of the laser processing equipment, thus avoiding resource waste and ensuring uninterrupted operation. In this way, while ensuring accurate and timely capture and location of cooling system anomalies, the cost of anomaly monitoring for cooling systems used in laser processing equipment can be effectively reduced.

[0074] In an exemplary embodiment, the operating status includes system start / stop status and pipeline flow status; verifying the operating status of the cooling system includes steps S11-S14, wherein:

[0075] Step S11: Check whether the system start / stop status of the cooling system is in the on state;

[0076] Step S12: If the system start-stop state of the cooling system is in the on state, determine that the system start-stop state verification of the cooling system has passed.

[0077] The system start / stop status can refer to the on or off state of the cooling system.

[0078] For example, the system start-stop status information of the cooling system can be obtained, and it can be determined whether the system start-stop status information indicates that the cooling system is in the on state; if it is determined that the cooling system is in the on state, the system start-stop status verification of the cooling system is passed; if it is determined that the cooling system is not in the on state, the system start-stop status verification of the cooling system is failed.

[0079] In some feasible implementations, if the system start-stop status verification of the cooling system fails, the operation of starting the cooling system can be automatically executed. Then, the process returns to the step of checking whether the system start-stop status of the cooling system is in the on state, until the system start-stop status verification of the cooling system passes, or the number of loops reaches a preset threshold. If the start-stop status verification still fails after reaching the preset threshold, an abnormal start-stop status alarm can be issued to remind relevant personnel to handle the abnormal start-stop status of the cooling system in a timely manner.

[0080] Step S13: If the system start-stop status verification of the cooling system passes, check whether the pipeline flow status of the cooling system is in a flow state.

[0081] Step S14: If the cooling system piping is in a flow state, the cooling system piping flow state verification is confirmed to be passed.

[0082] The pipeline flow status refers to the flow state of the cooling medium within the pipes of the cooling system. In some feasible implementations, the pipes in the cooling system can be segmented, and the pipeline flow status can include the flow status of each segment. It is understood that when the cooling system is stopped, the lack of driving force or other factors may cause the pipeline flow status to be falsely detected as non-flowing. Therefore, detecting the pipeline flow status only after confirming that the cooling system is on can reduce unnecessary false detections and mishandling.

[0083] For example, after determining that the cooling system is in the on state, the pipe flow status information of the cooling system can be obtained, and it can be determined whether the pipe flow status information indicates that the pipes in the cooling system are in a connected state; if it is determined that the pipes in the cooling system are in a connected state, the pipe flow status verification of the cooling system is determined to be passed; if it is determined that the pipes in the cooling system are not in a connected state, the pipe flow status verification of the cooling system is determined to be failed.

[0084] In some feasible implementations, the flow status of the cooling system can be determined by detecting the on / off status of each valve in the pipeline.

[0085] In some feasible implementations, if the cooling system's pipe flow status verification fails, a pipe connection operation can be automatically executed. Then, the process returns to the step of verifying the cooling system's pipe flow status until the verification passes, or the number of cycles reaches a preset threshold. If the preset threshold is reached and the pipe flow status still fails, a pipe flow status anomaly alarm can be triggered to alert relevant personnel to address the anomaly in the cooling system's pipe flow status promptly.

[0086] In this embodiment, the system start-up / shutdown status and pipeline flow status of the cooling system usually do not change after the laser processing equipment starts working. Therefore, if the system start-up / shutdown status and pipeline flow status of the cooling system are verified to be valid before the laser processing equipment starts working, there is no need to verify the system start-up / shutdown status and pipeline flow status of the cooling system again if any abnormality occurs later. This can reduce the monitoring burden of the cooling system on the laser processing stage of the laser processing equipment and effectively save resources.

[0087] In one exemplary embodiment, detecting whether the cooling system's piping is in a flow state includes:

[0088] The system detects the target functional modules activated by the laser processing equipment in the next laser processing stage, and checks whether the target valves corresponding to each target functional module are in the open state. If all target valves are in the open state, the system determines that the cooling system pipeline is in the flow state. If at least one target valve is not in the open state, the system determines that the cooling system pipeline is not in the flow state.

[0089] The laser processing equipment may include multiple functional modules, such as at least one of a laser, galvanometer, rotating mirror, and aperture. The laser may be further divided into a light source, laser head, etc. The specific division of functional modules can be based on actual conditions, and this embodiment does not impose any limitations on this. Functional modules can be divided into non-essential functional modules and essential functional modules. Essential functional modules refer to those that must be activated in each laser processing process; non-essential functional modules refer to those that are not required to be activated in each laser processing process. For essential functional modules, pipelines can be deployed in series; for non-essential functional modules, pipelines can be deployed in parallel. Opening or closing any parallel pipeline will not affect the flow of the entire pipeline. Therefore, valves can be installed on each parallel pipeline for individual control, thereby cooling the working functional modules without wasting resources cooling inactive functional modules, thus improving resource utilization. For example, a laser processing equipment may be equipped with multiple laser heads. In actual laser processing, only some laser heads may need to be activated. Therefore, it is sufficient to ensure that the pipelines corresponding to the activated laser heads are in a flowing state. As another example, a laser processing equipment may be equipped with multiple optical deflection devices such as galvanometers and rotating mirrors. In actual laser processing, only some of them may be activated according to the actual requirements of processing accuracy. Therefore, it is sufficient to ensure that the pipelines corresponding to the activated optical deflection devices are in a flowing state.

[0090] For example, the working information of the laser processing equipment can be obtained first, and the target functional module to be activated in the next laser processing stage can be determined based on the working information. Then, it can be detected whether the valve corresponding to each target functional module is in the open state. If each target valve is in the open state, it can be determined that the pipeline of the cooling system is in the flow state. If at least one target valve is not in the open state, it can be determined that the pipeline of the cooling system is not in the flow state.

[0091] In some feasible implementations, if it is determined that the cooling system's piping is not in a flow state, the target valve can be opened automatically. Then, the process returns to checking whether the target valves corresponding to each target functional module are open, until the cooling system's piping is in a flow state, or the number of cycles reaches a preset threshold. If, after reaching the preset threshold, at least one target valve is still not open, a valve opening anomaly alarm can be triggered to remind relevant personnel to promptly address the valve opening anomaly in the cooling system.

[0092] In this embodiment, by detecting the opening status of the target valve corresponding to the target functional module activated in the next laser processing stage, it can be ensured that the target functional module in the working state in the laser processing equipment can be cooled, reducing unnecessary abnormal detection and processing operations and improving resource utilization.

[0093] In one exemplary embodiment, the medium monitoring data includes at least one of a medium temperature value, a medium flow rate value, and a medium pressure value; acquiring the medium monitoring data and verifying the medium monitoring data includes at least one of the following:

[0094] The temperature of the cooling medium in the cooling system is collected by a temperature sensor, and it is detected whether the medium temperature is higher than the preset lower temperature limit and lower than the preset upper temperature limit.

[0095] The flow rate of the cooling medium in the cooling system is collected by a flow meter, and it is detected whether the flow rate is higher than the preset lower limit and lower than the preset upper limit.

[0096] The flow meter collects the pressure value of the cooling medium in the cooling system and detects whether the medium pressure value is higher than the preset lower pressure limit and lower than the preset upper pressure limit.

[0097] For example, the cooling system may be equipped with at least one temperature sensor and at least one flow meter. When the cooling system's operating status verification is passed and the laser processing equipment is in the laser processing stage, the temperature sensor can collect the temperature value of the cooling medium in the pipeline in real time or periodically. The collected medium temperature value is compared with preset lower and higher temperature limits. If the medium temperature value is higher than the preset lower limit but lower than the preset higher limit, the medium temperature value verification is considered passed. If the medium temperature value is less than or equal to the preset lower limit, or greater than or equal to the preset higher limit, the medium temperature value verification is considered failed. The flow meter can collect the medium flow rate value of the cooling medium in the pipeline in real time or periodically, and compare the collected medium flow rate value with a preset flow rate value. The flow rate is compared with the preset low flow rate limit and the preset high flow rate limit. If the flow rate value is higher than the preset low flow rate limit but lower than the preset high flow rate limit, the flow rate value verification is considered successful. If the flow rate value is less than or equal to the preset low flow rate limit, or greater than or equal to the preset high flow rate limit, the flow rate value verification is considered unsuccessful. Alternatively, the flow meter can collect the pressure value of the cooling medium in the pipeline in real time or at regular intervals, and compare the collected pressure value with the preset low pressure limit and the preset high pressure limit. If the pressure value is higher than the preset low pressure limit but lower than the preset high pressure limit, the pressure value verification is considered successful. If the pressure value is less than or equal to the preset low pressure limit, or greater than or equal to the preset high pressure limit, the pressure value verification is considered unsuccessful.

[0098] In this embodiment, temperature sensors and flow meters can be used to comprehensively monitor the temperature, pressure and flow rate of the cooling medium, so as to detect cooling system abnormalities in a timely manner and reduce the risks caused by cooling system abnormalities.

[0099] In one exemplary embodiment, the laser processing equipment includes multiple cooling modules; the cooling system includes pipes connected to each cooling module; temperature sensors are deployed at the inlet and outlet of each cooling module; the medium monitoring data also includes the medium temperature rise value; the medium temperature value includes the inlet medium temperature value and the outlet medium temperature value; after acquiring the medium temperature value of the cooling medium in the cooling system through the temperature sensors, the system further includes:

[0100] The difference between the outlet medium temperature and the inlet medium temperature is obtained, and the difference is determined as the medium temperature rise value; the medium temperature rise value is detected to see if it is higher than the preset temperature rise limit.

[0101] The cooling system can employ liquid cooling. The laser processing equipment includes multiple cooling modules, which can be configured with pipes or other conductive devices tailored to the structure and requirements of different functional modules. The cooling system's pipes can sequentially connect the inlet and outlet of each cooling module, forming a cooling medium loop. The cooling medium flows into the cooling module, carrying away the heat generated by the corresponding functional module. Therefore, there will be a temperature difference between the cooling medium entering and exiting the cooling module. A significant temperature difference may affect the cooling effect of the cooling medium on subsequent functional modules.

[0102] For example, after collecting the inlet and outlet medium temperature values ​​of each cooling module through temperature sensors, the outlet medium temperature value can be subtracted from the inlet medium temperature value, and the calculated difference can be determined as the medium temperature rise value of the cooling module. Then, the medium temperature rise value can be compared with the preset temperature rise limit. If the medium temperature rise value is lower than the preset temperature rise limit, the medium temperature rise value verification can be determined to be successful; if the medium temperature rise value is higher than the preset temperature rise limit, the medium temperature rise value verification can be determined to be unsuccessful.

[0103] In some feasible implementations, if the medium temperature rise value verification fails, the medium temperature rise value can be reduced by increasing the flow rate or decreasing the medium temperature. The process then returns to the step of checking if the medium temperature rise value exceeds a preset temperature rise limit, continuing until the medium temperature rise value verification passes or the number of cycles reaches a preset threshold. If the medium temperature rise value verification still fails after reaching the preset threshold, an abnormal medium temperature rise alarm can be issued to remind relevant personnel to promptly address any abnormal medium temperature rise in the cooling system.

[0104] In this embodiment, monitoring the temperature rise of the medium can detect anomalies earlier than monitoring the temperature value, thereby improving the timeliness of anomaly monitoring and handling and reducing the risks caused by cooling system anomalies.

[0105] In one exemplary embodiment, such as Figure 2 As shown, the method also includes:

[0106] Step S100: After the cooling system is initialized, the cooling circuit flow direction of each cooling module in the laser processing equipment is verified.

[0107] It should be noted that during the inspection, maintenance, or replacement of parts in laser processing equipment or cooling systems, the pipeline connection between the cooling system and the laser processing equipment may be disconnected and then reconnected after the inspection, maintenance, or replacement of parts is completed. In this case, the flow direction of the cooling circuit may be abnormal. For example, the inlet and outlet of the cooling module in the laser processing equipment may be reversed. Since the laser processing equipment generates a lot of heat during operation, the cooling module in the laser processing equipment may be equipped with a one-way valve. If a one-way valve is installed, the abnormal flow direction of the cooling circuit will cause the cooling circuit to be disconnected, and subsequent functional modules will not be cooled.

[0108] For example, after each initialization of the cooling system, the flow direction of the cooling medium at at least one of the inlet and outlet of the cooling module can be detected by a flow meter, and the detected flow direction can be verified to be consistent with the preset flow direction. If the detected flow direction is consistent with the preset flow direction, the cooling circuit flow direction verification is determined to be successful; if the detected flow direction is inconsistent with the preset flow direction, the cooling circuit flow direction verification is determined to be unsuccessful. For instance, if the cooling medium at the inlet flows into the inlet, the cooling circuit flow direction verification at that location is determined to be successful; if the cooling medium at the outlet flows into the outlet, the cooling circuit flow direction verification at that location is determined to be unsuccessful. The flow direction of the cooling medium can be determined based on the sign of the flow velocity.

[0109] Step S200: If the cooling circuit flow direction verification of at least one cooling module fails, the cooling module that fails the verification is identified as a circuit abnormal cooling module, and a circuit abnormal alarm is output. The circuit abnormal alarm is used to prompt the switching of the circuit input terminal and the circuit output terminal corresponding to the circuit abnormal cooling module.

[0110] For example, if the cooling circuit flow direction verification of at least one cooling module fails, the cooling module that fails the verification is identified as a circuit abnormal cooling module, and a circuit abnormal alarm is output. The circuit abnormal alarm can be in any form such as text, voice, or image, and is used to prompt the switching of the circuit input terminal and circuit output terminal corresponding to the circuit abnormal cooling module. If the cooling circuit flow direction verification of all cooling modules passes, no processing is required and no abnormal alarm is required.

[0111] In this embodiment, since the cooling system needs to be initialized after the pipeline connection between the cooling system and the laser processing equipment is disconnected and reconnected, by verifying the cooling circuit flow direction after each initialization of the cooling system, abnormal cooling circuit flow direction can be effectively captured, and the detection frequency of abnormal cooling circuit flow direction can be effectively reduced, thereby improving resource utilization.

[0112] In some feasible implementations, such asFigure 3 As shown, the laser processing equipment can be a laser drilling machine, which includes a laser, a galvanometer, an aperture, and optical path lenses. The cooling system includes a coolant supply device, a liquid distribution device, a liquid collection device, a temperature sensor, a flow meter, and pipelines. The coolant supply device is a frequency converter-enabled cooling device that can send control commands to the laser drilling machine to start, stop, adjust speed, and adjust temperature, supplying coolant to the laser, galvanometer, aperture, and optical path lenses within the laser drilling machine. After flowing out of the cooling supply device, the coolant flows to temperature sensor 1. Temperature sensor 1 monitors whether the temperature of the coolant is within the range of 21℃±0.1℃. When the coolant temperature reaches the set value, the cooling supply device controls the temperature change of the coolant within the range of ±0.1℃. If the temperature is abnormal, an abnormal signal is sent to the laser drilling machine. When the coolant flows from temperature sensor 1 to flow meter 1, flow meter 1 provides real-time feedback on the flow rate to the laser drilling machine. If the flow rate is >15L / M and the flow rate value is negative, an alarm signal is sent to the laser drilling machine to remind that the pipeline of the cooling supply device or flow meter 1 is reversed and the direction of coolant inflow and outflow needs to be reversed. The laser drilling machine calculates the coolant pressure based on the diameter of the supply pipeline. The pressure must be maintained between 0.4 MPa and 0.6 MPa. When the flow rate or pressure does not meet the requirements, the laser drilling machine controls the cooling supply device to adjust the speed. If the speed adjustment fails to meet the requirements after more than 5 adjustments, the machine is stopped for inspection to check for malfunctions in the cooling supply device or blockages in the supply circuit. After the coolant reaches the distributor, the distributor is equipped with cooling interfaces of different diameters according to the flow rate required by the laser, galvanometer, etc. The coolant then flows back to the cooling supply device through the collection device to re-cool the coolant.

[0113] The process involves the coolant flowing from the distributor into the laser to remove heat generated during laser operation. Temperature sensor 2 monitors the temperature of the coolant flowing out of the laser. When the coolant temperature exceeds 25°C, the flow rate of the coolant supply device is adjusted based on the data from flow meter 1 to meet the laser's cooling requirements. If the requirements are not met after five adjustments, an alarm is triggered, and the machine is shut down for maintenance. When the coolant flows from temperature sensor 2 into flow meter 2, flow meter 2 sends the flow rate information to the laser drilling machine in real time. The laser drilling machine calculates the pressure value based on the flow rate information and determines whether it meets the laser's required pressure of 0.4 MPa and flow rate of 9.5 L / min. If these values ​​are lower, the laser drilling machine sends a command to the coolant supply device to adjust the flow rate to meet the laser's cooling requirements. If the requirements are not met after five adjustments, an alarm is triggered, and the machine is shut down for maintenance. If the flow rate is negative, an alarm signal is sent to the laser drilling machine, indicating that the laser or flow meter 2's piping is reversed and the coolant inlet / outlet direction needs to be reversed.

[0114] The system involves the coolant flowing from the distributor into the galvanometer to remove the heat generated during operation. Temperature sensor 3 monitors the temperature of the coolant flowing out of the galvanometer. When the coolant temperature exceeds 21.5℃, the flow rate of the cooling supply device is adjusted based on the data from flow meter 1 to meet the galvanometer's cooling requirements. If the requirements are not met after five adjustments, an alarm is triggered and the system is shut down for maintenance. When the coolant flows from temperature sensor 3 into flow meter 3, flow meter 3 sends the flow rate information to the laser drilling machine in real time. The laser drilling machine calculates the pressure value based on the flow rate information and determines whether the pressure value of 0.4 MPa and the flow rate of 3 L / min required by the galvanometer are met. If these values ​​are lower, the laser drilling machine sends a command to the cooling supply device to adjust the flow rate to meet the laser's cooling requirements. If the requirements are not met after five adjustments, an alarm is triggered and the system is shut down for maintenance. If the flow rate is negative, an alarm signal is sent to the laser drilling machine, indicating that the pipes of the galvanometer or flow meter 2 are reversed and the coolant inlet / outlet direction needs to be reversed.

[0115] The coolant flows from the distributor into the aperture to carry away the heat generated when the aperture is working. The temperature of the coolant flowing out of the aperture is monitored by the temperature sensor 4. When the temperature of the coolant exceeds 25°C, the flow rate of the coolant supply device is adjusted by checking the data of the flow meter 1 to meet the cooling requirements of the aperture. If the requirements are still not met after 5 adjustments, an alarm is triggered and the machine is shut down for maintenance.

[0116] The coolant flows from the liquid distribution device into the optical path lens to carry away the heat generated when the optical path lens is working. The temperature of the coolant flowing out of the optical path lens is monitored by the temperature sensor 5. When the temperature of the coolant exceeds 25°C, the flow rate of the coolant supply device is adjusted by checking the data of the flow meter 1 to meet the cooling requirements of the optical path lens. If the requirements are still not met after 5 adjustments, an alarm is triggered and the machine is shut down for maintenance.
