Description

Technical Field

[0001] The present invention relates to the technical field of DCS operation and maintenance systems, and in particular to a DCS operation and maintenance system and method based on a large model. Background Art

[0002] The DCS operation and maintenance system based on large models is a system that uses large models and data analysis technology to monitor, diagnose and predict equipment. It combines functions such as data acquisition, real-time monitoring, fault diagnosis, and predictive maintenance to improve the reliability, safety and performance of equipment.

[0003] In terms of laser cutting machines, the DCS operation and maintenance system based on large models can conduct all-round detection of laser cutting machines. First, the operating data of the laser cutting machine, including temperature, pressure, vibration and other parameters, is collected in real time through sensors and instruments. Then, the system compares and analyzes these data with the pre-built large model to determine whether the equipment is operating normally.

[0004] When the system detects an abnormality in the laser cutting machine, such as increased temperature or vibration, it will immediately sound an alarm and automatically diagnose the problem. By analyzing the historical data in the model and the behavioral characteristics of similar equipment, the system can quickly locate the possible cause of the failure and provide corresponding solutions. At the same time, the system can also predict the life and maintenance needs of the equipment, and provide users with optimized and planned maintenance suggestions;

[0005] When the DCS operation and maintenance system of the laser cutting machine is in use, it is unable to detect the metal being cut. Different metals have different maximum cutting thicknesses. If the thickness of the metal being cut exceeds the maximum cutting thickness of the laser cutting machine when the laser cutting machine is used to cut metal, it will not only seriously affect the cutting effect, but also cause the laser to overheat and be damaged, resulting in property loss. At the same time, when the laser cutting machine is used to cut metal, it is necessary to manually adjust the cutting parameters of the laser cutting machine according to different cutting metals, such as laser power, cutting speed and focusing depth, etc. At the same time, workers are required to adjust the cutting template according to the metal being cut. If the cutting parameters or cutting template are adjusted incorrectly due to negligence of the staff, it will not only seriously affect the cutting effect, but even cutting errors may cause the metal sheet to be scrapped, resulting in property loss.

The infrared rangefinder sensor 912 is used here to detect the distance between the infrared rangefinder sensor 912 and the top end of the laser cutting machine 1, thereby judging the thickness of the metal plate 18.

[0039] Working principle: When in use, start the hydraulic rod 11, use the hydraulic rod 11 to pull the lifting plate 12 to drive the pressing plate 15 to move downward, wait for the second roller 17 to contact the top of the metal plate 18, and then use the metal plate 18 to push the pressing plate 15 to move upward along the inner cavity of the lifting plate 12 until the pressing block 16 contacts the pressure sensor 14, and use the pressure sensor 14 to detect the extrusion force applied by the first roller 3 and the second roller 17 to the metal plate 18 until the extrusion force reaches a certain value. When the first roller 3 rotates, the extrusion force applied by the first roller 3 and the second roller 17 to the metal plate 18 is used to prompt the metal plate 18 to move, start the second motor 914, and use the output end of the second motor 914 to drive the worm 915 to rotate, and the worm 915 The rotation causes the worm gear 913 to rotate. The rotational force generated by the rotation of the worm gear 913 causes the screw 96 to drive the spectrometer sensor 910 to move downward through the sleeve 97. At the same time, due to the shielding of the metal plate 18 by the support frame 91, the infrared rangefinder sensor 912 cannot detect the metal plate 18. As the spectrometer sensor 910 moves downward, the infrared rangefinder sensor 912 is used to monitor the distance between it and the top of the laser cutting machine 1 in real time. After the bottom end of the spectrometer sensor 910 contacts the metal plate 18, the sleeve 97 continues to move downward, causing the spectrometer sensor 910 to move upward in the inner cavity of the sleeve 97 and squeeze the spring 99 to undergo elastic deformation. At this time, although the sleeve 97 is still moving, the spectrometer sensor The positions of the spectrometer sensor 910 and the infrared rangefinder sensor 912 have not changed. When the infrared rangefinder sensor 912 detects that the output end of the second motor 914 is rotating, and the distance between the infrared rangefinder sensor 912 and the top of the laser cutting machine 1 has not changed, it means that the spectrometer sensor 910 is in contact with the top of the metal sheet 18, and then the second motor 914 is automatically turned off at this time, and the spectrometer sensor 910 is used to detect the material of the metal sheet 18, and the infrared rangefinder sensor 912 is used to detect the distance between it and the top of the laser cutting machine 1, so as to judge the thickness of the metal sheet 18, and pass the information to the data analysis module, and use the data analysis module to pass it to the DCS operation and maintenance control module through the metal detection module. The DCS operation and maintenance control module then transmits the information to the database module, and uses the matching module to determine the thickness of the metal cut by the laser cutting machine 1 according to the material of the detected metal sheet 18. If the thickness of the metal sheet 18 detected by the infrared rangefinder sensor 912 exceeds the thickness of the metal cut by the laser cutting machine 1, a reminder is sent to the DCS operation and maintenance control module, and the hydraulic rod 11 is started to push the lifting plate 12 to return to the initial position, and subsequent work is stopped. If the thickness of the metal sheet 18 detected by the infrared rangefinder sensor 912 does not exceed the thickness of the metal cut by the laser cutting machine 1, the information is transmitted to the DCS operation and maintenance control module through the metal detection module, and the cutting parameter setting module is used to set the cutting parameters required for cutting the metal sheet 18.At the same time, the color recognition sensor 93 is used to detect the color of the color coating mark 19 to pass the information to the data analysis module, and then the information is passed to the DCS operation and maintenance control module through the metal detection module, and the cutting template setting module is used to set the cutting template of the laser cutting machine 1. After the setting is completed, the output end of the second motor 914 is used to rotate in the opposite direction, thereby prompting the screw 96 to drive the spectrometer sensor 910 to move upward to the initial position through the sleeve 97, and the first motor 8 is started. The output end of the first motor 8 drives the first roller 3 located in the middle to rotate, and at the same time, the cooperation between the first sprocket 4, the first chain 5, the second sprocket 6 and the second chain 7 is used to prompt The three first rollers 3 rotate synchronously clockwise, thereby causing the metal sheet 18 to move to the right until it moves to a suitable position, and the hydraulic rod 11 is activated to push the lifting plate 12 back to the urged position. The laser cutting machine 1 uses the set cutting parameters and cutting template to cut the metal sheet 18. When the device is in use, it can automatically detect the material and thickness of the metal sheet 18, thereby avoiding the situation where the thickness of the cut metal sheet 18 exceeds the maximum cutting thickness of the laser cutting machine 1. At the same time, the device can also provide accurate cutting parameters and template suggestions through data analysis and model comparison, thereby avoiding or reducing losses caused by human operation and avoiding property losses.

2. A DCS operation and maintenance system based on a large model according to claim 1, characterized in that: The distance between the pressure block (16) and the pressure sensor (14) is smaller than the distance between the top of the pressure plate (15) and the top of the lifting plate (12).

3. The working method of a DCS operation and maintenance system based on a large model according to claim 2 is characterized in that: The following steps are involved: Step 1: Using a hydraulic rod (11) to pull the lifting plate (12) to drive the pressing plate (15) to move downward, and wait until the second roller (17) contacts the top of the metal plate (18). At this time, using the metal plate (18) to push the pressing plate (15) to move upward along the inner cavity of the lifting plate (12) until the pressing block (16) contacts the pressure sensor (14). Using the pressure sensor (14) to detect the extrusion force applied by the first roller (3) and the second roller (17) to the metal plate (18) until the extrusion force reaches a certain value, when the first roller (3) rotates, using the extrusion force applied by the first roller (3) and the second roller (17) to the metal plate (18) to cause the metal plate (18) to move; Step 2: Start the second motor (914), and use the output end of the second motor (914) to drive the worm (915) to rotate. The rotation of the worm (915) causes the worm wheel (913) to rotate. The rotational force generated by the rotation of the worm wheel (913) causes the screw (96) to drive the spectrometer sensor (910) to move downward through the sleeve (97). At the same time, due to the shielding of the metal plate (18) by the support frame (91), the infrared rangefinder sensor (912) cannot detect the metal plate (18). As the spectrometer sensor (910) moves downward, the infrared rangefinder sensor (912) is used to monitor the distance between it and the top of the laser cutting machine (1) in real time. After the bottom end of the spectrometer sensor (910) contacts the metal plate (18), the sleeve (97) continues to move downward, causing the spectrometer sensor (910) to move downward in the sleeve (97). The inner cavity moves upward and squeezes the spring (99) to undergo elastic deformation. Although the sleeve (97) is still moving at this time, the positions of the spectrometer sensor (910) and the infrared rangefinder sensor (912) do not change. When the infrared rangefinder sensor (912) detects that the output end of the second motor (914) is rotating, the distance between the infrared rangefinder sensor (912) and the top of the laser cutting machine (1) does not change, indicating that the spectrometer sensor (910) and the top of the metal plate (18) are in contact. At this time, the second motor (914) is automatically turned off, the spectrometer sensor (910) is used to detect the material of the metal plate (18), and the infrared rangefinder sensor (912) is used to detect the distance between it and the top of the laser cutting machine (1), thereby determining the thickness of the metal plate (18) and transmitting the information to the data analysis module; Step 3: Use the data analysis module to pass the information to the DCS operation and maintenance control module through the metal detection module, and the DCS operation and maintenance control module then passes the information to the database module, and uses the matching module to determine the thickness of the metal cut by the laser cutting machine (1) according to the material of the detected metal plate (18). If the thickness of the metal plate (18) detected by the infrared rangefinder sensor (912) exceeds the thickness of the metal cut by the laser cutting machine (1), a reminder is sent to the DCS operation and maintenance control module, and the hydraulic rod (11) is started to push the lifting plate (12) back to the initial position, and subsequent work is stopped. If the thickness of the metal plate (18) detected by the infrared rangefinder sensor (912) does not exceed the thickness of the metal cut by the laser cutting machine (1), the information is passed to the DCS operation and maintenance control module through the metal detection module, and the cutting parameter setting module is used to set the cutting parameters required for cutting the metal plate (18), and the color recognition sensor (93) is used to detect the color coating mark. (19) to transmit information to the data analysis module, and then transmit the information to the DCS operation and maintenance control module through the metal detection module, and use the cutting template setting module to set the cutting template of the laser cutting machine (1). After the setting is completed, the output end of the second motor (914) is used to rotate in the opposite direction, thereby prompting the screw (96) to drive the spectrometer sensor (910) to move upward to the initial position through the sleeve (97), and the output end of the first motor (8) is used to drive the first roller (3) located in the middle to rotate. At the same time, the cooperation between the first sprocket (4), the first chain (5), the second sprocket (6) and the second chain (7) is used to prompt the three first rollers (3) to rotate synchronously clockwise, thereby prompting the metal plate (18) to move to the right until it moves to a suitable position, and the hydraulic rod (11) is started to push the lifting plate (12) back to the prompting position. The laser cutting machine (1) cuts the metal plate (18) using the set cutting parameters and cutting template.
