The terms used herein are for the purpose of describing the embodiments of the present application only.

[0022] The present application embodiment provides a surface polishing control system for a carbon dioxide cylinder, such as Figure 1 As shown, the system comprises:

[0023] The data acquisition module 11 is used to execute step 1: read the predetermined characteristic dimension, and collect multi-dimensional features of the cylinder material based on the predetermined characteristic dimension to obtain target material characteristic data, wherein the cylinder material is the raw material of the carbon dioxide cylinder.

[0024] The optimization space construction module 12 is used to execute step 2: randomly obtain a first polishing strategy in the polishing optimization space, wherein the polishing optimization space is a polishing control optimization space formed based on a predetermined polishing parameter threshold of a predetermined polishing indicator.

[0025] The surface temperature prediction module 13 is used to execute step three: using the first polishing strategy as input information of a surface temperature prediction model to obtain a first predicted surface temperature, wherein the surface temperature prediction model is trained by machine learning based on data from the historical polishing control records of the cylinder material.

[0026] Read the predetermined characteristic dimensions, which include the chemical composition, physical properties, surface roughness, etc. of the material. Based on these predetermined characteristic dimensions, collect multi-dimensional features of the raw materials of the carbon dioxide cylinder to obtain the target material characteristic data. Subsequently, randomly obtain the first polishing strategy in the polishing optimization space, wherein the polishing optimization space is a polishing control optimization space formed based on the predetermined polishing parameter threshold of the predetermined polishing index, the predetermined polishing index includes polishing particle size, polishing pressure, polishing speed and polishing direction, and the predetermined polishing parameter threshold is the control parameter threshold range corresponding to each polishing index, and the predetermined polishing parameter threshold is obtained based on the target material physical characteristic data in the target material characteristic data. Randomly obtain the polishing strategy of each polishing index in the corresponding polishing parameter threshold in the polishing optimization space to obtain the first polishing strategy. Step three: Use the first polishing strategy as the input information of the surface temperature prediction model to obtain the first predicted surface temperature, wherein the surface temperature prediction model is trained by machine learning the data in the historical polishing control record of the cylinder material. When constructing the surface temperature prediction model, a large number of historical polishing control records are collected from the production line and laboratory. These records should include specific cylinder materials and corresponding polishing strategies, i.e., polishing indicators and specific polishing parameters, and include real-time measured surface temperatures of cylinders under different polishing strategies. Training data is constructed based on the data in the historical polishing control records. The artificial neural network in the machine learning algorithm is selected to conduct supervised training of the model based on the training set, and the accuracy is judged based on multiple predicted surface temperature results output by the model. When the accuracy of the model output meets the preset accuracy, the model training is completed, and the trained surface temperature prediction model is obtained.

[0027] like Figure 2As shown, the optimization space construction module 12 is further used to: extract the physical property data of the target material from the target material property data, analyze the physical property data of the target material to obtain a first parameter threshold of the first indicator in the predetermined polishing indicator, and construct the predetermined polishing parameter threshold based on the first parameter threshold.

[0028] The step 2 includes: extracting the target material physical property data from the target material property data, the target material physical property data including but not limited to the hardness, density, yield strength, tensile strength and toughness of the material. Analyzing the target material physical property data to obtain the first parameter threshold of the first indicator in the predetermined polishing index, and constructing the predetermined polishing parameter threshold based on the first parameter threshold. For example, if the predetermined polishing index includes polishing speed and polishing pressure, then the appropriate polishing speed and polishing pressure ranges can be determined based on the physical properties of the material such as hardness and density, and the parameter threshold of the indicator is constructed based on the polishing speed and polishing pressure ranges. Finally, construct the predetermined polishing parameter threshold based on the obtained parameter thresholds.

[0029] The detection signal acquisition module 14 is used to execute step four: when the first predicted surface temperature is at the surface temperature limit, the ultrasonic detection equipment is activated to perform dynamic detection on the first grinding test of the carbon dioxide cylinder based on the first grinding strategy to obtain a first grinding detection signal, and the surface temperature limit is determined by analyzing the target material chemical characteristic data in the target material characteristic data.

[0030] The comparison and analysis module 15 is used to execute step five: call the polishing fitness evaluation function to compare and analyze the first polishing detection signal with a predetermined signal to obtain a first polishing fitness.

[0031] The loop execution module 16 is used to execute step six: repeating steps two to five to obtain a second grinding adaptability of a second grinding strategy, where the second grinding strategy is different from the first grinding strategy.

[0032] The optimization module 17 is used to execute step seven: when the second polishing fitness is greater than the first polishing fitness, the second polishing strategy is used as the optimal polishing strategy; when the second polishing fitness is less than the first polishing fitness, the first polishing strategy is used as the optimal polishing strategy.

[0033] The polishing control module 18 is used to execute step eight: continue to iterate until the iteration number limit is reached, and perform surface polishing control on the carbon dioxide cylinder based on the optimal polishing strategy at that time.

[0034] Specifically, after completing the temperature prediction of the target material characteristic data polishing strategy to obtain the first predicted surface temperature, it is determined whether the first predicted surface temperature is within the surface temperature limit. The surface temperature limit is determined by analyzing the target material chemical characteristic data in the target material characteristic data, and is a temperature parameter value that does not affect the performance of the cylinder, ensuring that the material is not damaged by overheating during the polishing process. When it is greater than the temperature surface temperature limit, the shutdown operation is performed. When the first predicted surface temperature is less than or equal to the surface temperature limit, the polishing temperature has no effect on the performance of the cylinder, and the ultrasonic detection device is activated to dynamically detect the first polishing test of the carbon dioxide cylinder based on the first polishing strategy to obtain a first polishing detection signal. The first polishing detection signal includes ultrasonic detection receiving signals at multiple angles. At the 0° position, the ultrasonic transmission signal passes through the cylinder at the 0° position and its two opposite cylinder surfaces, transmits a signal at the 0° position, and receives a signal at the 180° position opposite to the 0° position of the cylinder. Further, the polishing fitness evaluation function is retrieved to compare and analyze the first polishing detection signal with the predetermined signal to obtain the first polishing fitness.

[0035] The first detection signal is compared with the predetermined signal according to the grinding fitness evaluation function to obtain the first fitness of the first detection angle, and the first grinding fitness is calculated based on the first fitness. The expression of the grinding fitness evaluation function is as follows:

[0036]

[0037] Wherein, l(x) refers to the first fitness of the first detection angle x, refers to the total deviation between the first detection signal and the signal time domain features of the predetermined signal at the first detection angle x, i refers to the i-th time domain feature among the m signal time domain features, α i refers to the weight coefficient of the i-th time domain feature, refers to the total deviation between the first detection signal and the signal frequency domain characteristics of the predetermined signal at the first detection angle x, j refers to the jth frequency domain feature among the n signal frequency domain features, β jRefers to the weight coefficient of the jth frequency domain feature, a and b are the first coefficient and the second coefficient respectively, and the sum of a and b is 1. Step 6: Repeat steps 2 to 5 to obtain the second polishing fitness of the second polishing strategy, the second polishing strategy is different from the first polishing strategy, and the acquisition method of the second polishing strategy is the same as the acquisition method of the first polishing strategy. Step 7: After processing the second polishing strategy in steps 3 to 5, obtain the corresponding second polishing fitness. When the second polishing fitness is greater than the first polishing fitness, the second polishing strategy is used as the optimal polishing strategy, and when the second polishing fitness is less than the first polishing fitness, the first polishing strategy is used as the optimal polishing strategy. Step 8: Continue to iterate until the iteration number limit is reached, the iteration number limit is the preset iteration number, and when the iteration number limit is reached, the optimization iteration is completed, and the current optimal polishing strategy is obtained to control the surface polishing of the carbon dioxide cylinder. The technical problems of low polishing efficiency, unstable polishing quality, inaccurate surface temperature control and lack of intelligent control in the surface polishing process of carbon dioxide cylinders in the prior art are solved. By introducing intelligent control and machine learning algorithms, the grinding efficiency is improved, the stability of the grinding quality of CO2 cylinders is ensured, the surface temperature is accurately controlled, and intelligent control of the grinding process is achieved.

[0038] The optimization space construction module 14 is also used to: obtain a first detection time. Combined with a predetermined detection trajectory, obtain a first detection angle of the ultrasonic detection device at the first detection time. Traverse the first detection time in the first grinding detection signal to obtain a first detection signal. Generate a first detection visual graph based on a first correspondence between the first detection angle and the first detection signal, and visually monitor the first grinding strategy through the first detection visual graph. Among them, the predetermined detection trajectory is a semicircular trajectory with the carbon dioxide cylinder as the center.

[0039] During the grinding test, the current detection time is recorded as the first detection time. This time point is the starting time for ultrasonic detection. The first detection angle of the ultrasonic detection device at the first detection time is obtained in combination with the predetermined detection trajectory. The predetermined detection trajectory is a semicircular trajectory with the carbon dioxide cylinder as the center. Based on the first detection time, the first grinding detection signal is traversed to obtain the first detection signal. The first detection signal is the signal received by the ultrasonic receiver at the first detection time. Furthermore, a first detection visual graph is generated based on the first corresponding relationship between the first detection angle and the first detection signal, and the first grinding strategy is visually monitored through the first detection visual graph.

[0040] The polishing control module 18 is also used to: obtain a first thickness of a first point of the carbon dioxide cylinder and match a first predetermined stress of the first thickness. Generate a stress distribution visual graph according to a second corresponding relationship between the first point and the first predetermined stress. Visually monitor the polishing quality of the carbon dioxide cylinder through the stress distribution visual graph.

[0041] During the grinding process, a key point on the carbon dioxide cylinder is selected and recorded as the first point. The thickness of the point is measured in real time using a thickness measuring device (such as an ultrasonic thickness gauge) to obtain the first thickness of the first point. According to the pre-established stress-thickness correspondence table, the first predetermined stress corresponding to the first thickness of the first point is matched, and the first predetermined stress at this time does not consider the physical properties of the specific material. The predetermined stress is obtained through experimental data and theoretical analysis based on the stress distribution law of the material at different thicknesses. Further, according to the correspondence between the first point and the first predetermined stress, a stress distribution visual graph is generated. The stress distribution visual graph graphically displays the stress distribution on the surface of the cylinder, reflecting the stress changes and distribution laws of the material during the grinding process. Finally, the carbon dioxide cylinder is visually monitored for grinding quality through the stress distribution visual graph. During the monitoring process, the stress state of each point on the surface of the cylinder can be intuitively understood through the stress distribution graph, and the stress concentration or excessive stress area that may occur during the grinding process can be discovered and handled in time. During the grinding process, the first point of the cylinder is selected, and the thickness of the point is measured using an ultrasonic thickness gauge. For example, the thickness of the first point is measured to be 15 mm. According to the measured thickness of 15mm, the corresponding predetermined stress is matched from the stress-thickness correspondence table. For example, the predetermined stress corresponding to the thickness of 15mm is 150MPa. The first point and the corresponding predetermined stress are input into the stress distribution generation module to generate a stress distribution visual graph, and multiple points and the corresponding predetermined stresses are acquired in a loop and displayed in the stress distribution visual graph. The visual graph shows the stress distribution at different points on the surface of the cylinder, and intuitively displays the stress state of the material during the grinding process. Through the stress distribution visual graph, the grinding quality can be monitored in real time, which helps to detect stress concentration or excessive stress areas during the grinding process, and timely adjust the grinding position to ensure uniform stress on the surface of the cylinder and guarantee the grinding quality.

[0042] The grinding control module 18 is also used to: read predetermined physical properties, and traverse the physical property data of the target material based on the predetermined physical properties to obtain predetermined physical property data. Feedback adjustment is performed on the first predetermined stress based on the predetermined physical property data. The predetermined physical properties include yield strength, tensile strength and toughness.

[0043] Read the predetermined physical properties, which are parameters in the target material property data, including yield strength, tensile strength and toughness, to obtain the predetermined physical property data. Since the acquisition of the first predetermined stress is based on the thickness-stress correspondence of the general material and does not take into account the specific material properties. By acquiring the predetermined physical property data, the first predetermined stress is feedback-adjusted based on the predetermined physical property data. When performing the feedback adjustment, a preset adjustment factor is obtained based on the parameter difference between the material properties of the general material and the predetermined physical property data, and the differences generated by the physical property data correspond to specific adjustment factors. Feedback adjustment of the first predetermined stress is performed based on the adjustment factor. For example, if the first predetermined stress is 150MPa and the adjustment factor is 1.05, the adjusted predetermined stress is 157.5MPa.

[0044] The embodiment of the present application performs step 1: reading a predetermined characteristic dimension, and collecting multi-dimensional characteristics of the cylinder material based on the predetermined characteristic dimension to obtain target material characteristic data, wherein the cylinder material is the raw material of the carbon dioxide cylinder. Step 2: randomly obtaining a first polishing strategy in the polishing optimization space, wherein the polishing optimization space is a polishing control optimization space formed by a predetermined polishing parameter threshold based on a predetermined polishing index. Step 3: using the first polishing strategy as input information of a surface temperature prediction model to obtain a first predicted surface temperature, wherein the surface temperature prediction model is obtained by machine learning data training in the historical polishing control record of the cylinder material. Step 4: when the first predicted surface temperature is at the surface temperature limit, activating an ultrasonic detection device to dynamically detect the first polishing test of the carbon dioxide cylinder based on the first polishing strategy, and obtaining a first polishing detection signal, wherein the surface temperature limit is determined by analyzing the target material chemical characteristic data in the target material characteristic data. Step 5: calling a polishing fitness evaluation function to compare and analyze the first polishing detection signal with a predetermined signal, and obtaining a first polishing fitness. Step six: Repeat steps two to five to obtain a second polishing fitness of a second polishing strategy, where the second polishing strategy is different from the first polishing strategy. Step seven: When the second polishing fitness is greater than the first polishing fitness, the second polishing strategy is used as the optimal polishing strategy; when the second polishing fitness is less than the first polishing fitness, the first polishing strategy is used as the optimal polishing strategy. Step eight: Continue to iterate until the iteration limit is reached, and perform surface polishing control on the carbon dioxide cylinder based on the optimal polishing strategy at that time. The technical problems of low polishing efficiency, unstable polishing quality, inaccurate surface temperature control and lack of intelligent control in the surface polishing process of carbon dioxide cylinders in the prior art are solved. By introducing intelligent control and machine learning algorithms, the polishing efficiency is improved, the stability of the polishing quality of carbon dioxide cylinders is ensured, the surface temperature is accurately controlled, and intelligent control of the polishing process is realized.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application. In some cases, the actions or steps recorded in the present application can be performed in an order different from that in the embodiment and can still achieve the desired results.
