[0002] Oxygen-free copper rods are metal materials with high conductivity, high strength and excellent corrosion resistance. They are widely used in many fields such as electricity, electronics, communications, construction and transportation. They are one of the indispensable basic materials in modern industry. In its production process, the quality control of each link is directly related to the performance and market competitiveness of the final product.

[0003] In the prior art, in the production process of oxygen-free copper rods, existing monitoring methods mostly rely on manual inspections and regular sampling tests. This method is not only inefficient, but also difficult to achieve real-time monitoring of the entire production process, and it is easy to miss key quality fluctuation points. Due to the limitations of monitoring and detection methods, quality problems that occur at the production site are difficult to detect in time. Even after they are discovered, it often takes a long time to analyze and solve the causes, which further aggravates the fluctuations in product quality and affects production efficiency. Therefore, the current production process of oxygen-free copper rods is inefficient and quality problems are difficult to detect and solve in a timely manner. Summary of the invention

[0005] In a first aspect, an embodiment of the present application provides a method for controlling the production of an oxygen-free copper rod, comprising:

[0006] Acquire first production data and first process parameters of the oxygen-free copper rod in the current production link; wherein the production link is continuous casting, rolling, annealing, drawing or wire winding, the first production data includes the length, diameter and oxygen content of the oxygen-free copper rod in the current production link, the first process parameter is a process parameter preset by the production equipment of the oxygen-free copper rod in the current production link, and the first process parameter includes at least one of temperature, pressure, tension and speed;

[0007] Determining a state value of the first process parameter; wherein the state value is a sign or code reflecting a current state of the first process parameter;

[0008] Obtaining a second process parameter of an oxygen-free copper rod in a next link of the current production link; wherein the second process parameter is a process parameter preset by a production equipment of the oxygen-free copper rod in the next link, and the second process parameter includes at least one of temperature, pressure, tension and speed;

[0009] In the case where it is determined that the first process parameter is adjusted according to the state value of the first process parameter, second production data is determined based on the first production data and the second process parameter; wherein the second production data includes the length, diameter and oxygen content of the oxygen-free copper rod in the next link;

Once a quality problem is found, the system can immediately trigger the adjustment mechanism to solve the quality problem in time, which is conducive to improving the quality of the oxygen-free copper rod in the subsequent production link.

[0073] In the related technology, in the production process of oxygen-free copper rods, the existing monitoring methods mostly rely on manual inspections and regular sampling tests. This method is not only inefficient, but also difficult to achieve real-time monitoring of the entire production process, and it is easy to miss key quality fluctuation points. Due to the limitations of monitoring and detection methods, quality problems that occur at the production site are difficult to detect in time. Even after they are discovered, it often takes a long time to analyze and solve the causes, which further aggravates the fluctuations in product quality and affects production efficiency. Therefore, the current production process of oxygen-free copper rods is inefficient and quality problems are difficult to detect and solve in a timely manner.

[0074] To solve the above problems, the embodiment of the present application provides a method, system and equipment for production control of oxygen-free copper rods. In the method, by obtaining the first production data and the first process parameter of the oxygen-free copper rod in the current production link, the state value of the first process parameter is determined and the second process parameter of the oxygen-free copper rod in the next link of the current production link is obtained; wherein, the first production data includes the length, diameter and oxygen content of the oxygen-free copper rod in the current production link, and by obtaining the key production data such as the length, diameter and oxygen content of the oxygen-free copper rod, the quality status of the oxygen-free copper rod in each production link can be accurately judged; when the first process parameter is determined to be adjusted according to the state value of the first process parameter, the second production data is determined based on the first production data and the second process parameter; when the production quality of the oxygen-free copper rod in the next link is determined to be unqualified based on the second production data, the second process parameter is adjusted. Therefore, the oxygen-free copper rod production control method provided in the embodiment of the present application uses the state value to monitor the adjustment of the process parameter. Once it is detected that the process parameter is adjusted, the production data of the next link is immediately predicted and determined based on the new production data and the process parameters of the subsequent link, so as to find quality problems in time. Once a quality problem is found, the system can immediately trigger the adjustment mechanism to solve the quality problem in time and ensure the quality of oxygen-free copper rods in subsequent production links. Through real-time monitoring and automatic adjustment of process parameters, it can quickly respond to changes in the production process, avoiding production stagnation and delays caused by untimely manual intervention or misjudgment, thereby significantly improving production efficiency.

[0075] The oxygen-free copper rod production control method provided in the embodiment of the present application can be applied to oxygen-free copper rod production control equipment. At this time, the oxygen-free copper rod production control equipment is the executor of the oxygen-free copper rod production control method provided in the embodiment of the present application. The embodiment of the present application does not impose any restrictions on the specific type of oxygen-free copper rod production control equipment.

[0076] The oxygen-free copper rod production control equipment can be connected to the production equipment of each production link of the oxygen-free copper rod. For example, the oxygen-free copper rod production control equipment can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), a desktop computer, a smart screen, a smart TV, a handheld device with wireless communication function, a computing device or other processing equipment connected to a wireless modem, a vehicle-mounted device, a vehicle networking terminal, a computer, a laptop computer, a handheld communication device, a handheld computing device, a satellite wireless device, etc., but not limited to this.

[0077] In order to better understand the oxygen-free copper rod production control method provided in the embodiment of the present application, the specific implementation process of the oxygen-free copper rod production control method provided in the embodiment of the present application is exemplarily introduced below.

[0078] Figure 1 A schematic flow chart of the oxygen-free copper rod production control method provided in an embodiment of the present application is shown, and the oxygen-free copper rod production control method includes:

[0079] S100, obtaining first production data and first process parameters of the oxygen-free copper rod in the current production link; wherein the production link is continuous casting, rolling, annealing, drawing or wire winding, the first production data includes the length, diameter and oxygen content of the oxygen-free copper rod in the current production link, the first process parameter is a process parameter preset by the production equipment of the oxygen-free copper rod in the current production link, and the first process parameter includes at least one of temperature, pressure, tension and speed.

[0080] It can be understood that the oxygen-free copper rod in the current production link is the oxygen-free copper rod output by the production link after being processed by the production link, rather than specifically referring to the final finished product.

[0081] Exemplarily, the first production data of the oxygen-free copper rod in the current production link can be obtained by real-time monitoring the length of the oxygen-free copper rod on the production line through a laser range sensor, real-time monitoring the diameter of the oxygen-free copper rod on the production line through a laser displacement sensor, and real-time monitoring the oxygen content of the oxygen-free copper rod on the production line through an electrochemical oxygen sensor. Of course, the length, diameter and oxygen content of the oxygen-free copper rod manually input can also be directly received.

[0082] Exemplarily, obtaining the first process parameter of the oxygen-free copper rod in the current production link may be that the oxygen-free copper rod production control equipment directly reads the set parameters on the production equipment of the oxygen-free copper rod. Of course, the first process parameter of the oxygen-free copper rod manually input may also be directly received.

[0083] S200, determining a state value of a first process parameter; wherein the state value is a sign or code reflecting a current state of the first process parameter.

[0084] Exemplarily, the state value of the first process parameter may be acquired in real time.

[0085] By determining the status value of the first process parameter and using the status value to monitor the adjustment of the first process parameter, once it is detected that the first process parameter is adjusted, the production data of the next link is immediately predicted and determined based on the new first production data and the process parameters of the subsequent links, so as to discover quality problems in time.

[0086] S300, obtaining a second process parameter of the oxygen-free copper rod in the next link of the current production link; wherein the second process parameter is a process parameter preset by the production equipment of the oxygen-free copper rod in the next link, and the second process parameter includes at least one of temperature, pressure, tension and speed.

[0087] It can be understood that the oxygen-free copper rod in the next link refers to the oxygen-free copper rod that is processed in the current production link and enters the next production link for further processing and then output.

[0088] Exemplarily, the oxygen-free copper rod production control equipment may query the preset process parameters of the production equipment of the oxygen-free copper rod in the next link.

[0089] S400, when it is determined that the first process parameter is adjusted according to the state value of the first process parameter, second production data is determined based on the first production data and the second process parameter; wherein the second production data includes the length, diameter and oxygen content of the oxygen-free copper rod in the next link.

[0090] It can be understood that after determining that the first process parameter is adjusted according to the state value of the first process parameter being the first state value, the second production data is predicted based on the first production data and the second process parameter.

[0091] For example, it may be determined whether the first process parameter is adjusted based on whether the check state value is a first state value (e.g., the state value is "V1") or a second state value (e.g., the state value is "V2"). When the state value is the first state value, it is determined that the first process parameter is adjusted; when the state value is the second state value, it is determined that the first process parameter is not adjusted.

[0092] For example, the random forest model may be used to predict the second production data based on the first production data and the second process parameters. For example, after the initial random forest model is trained and the performance of the random forest model is verified to be qualified by a cross-validation method, the first production data and the second process parameters are input into the random forest model to output the second production data.

[0093] In one possible implementation, see Figure 2 S400, when it is determined that the first process parameter is adjusted according to the state value of the first process parameter, before determining the second production data based on the first production data and the second process parameter, the oxygen-free copper rod production control method further includes:

[0094] S401, determining whether the first production data is within a preset first standard range.

[0095] It can be understood that judging whether the first production data is within the preset first standard range is judging whether the first production data is within a preset prescribed interval, and the preset prescribed interval can be set by ordinary technicians in the field according to actual needs and is not limited here.

[0096] For example, the first production data can be determined to be within the preset first standard range only when the length, diameter and oxygen content in the first production data all meet their respective corresponding ranges. If any one of the length, diameter and oxygen content does not meet any of its corresponding ranges, the first production data is determined to be not within the preset first standard range. For example, the first standard range is set as:

[0097]

[0098] S402: If the first production data is not within the first standard range, the current production link is controlled to stop production.

[0099] Exemplarily, when the oxygen-free copper rod production control device determines that the first production data is not within the first standard range, it may send a stop signal to the oxygen-free copper rod production equipment to control the current production link to stop production.

[0100] S403, determining first deviation information according to the first production data and the first standard range; wherein the first deviation information is used to indicate the size and direction of the deviation between the first production data and the first standard range.

[0101] For example, the difference or ratio between the first production data and the first standard range (i.e., the difference or ratio of the corresponding parameters between the first production data and the first standard range) can be calculated, and whether it exceeds the highest value or the lowest value of the first standard range is marked. For example, the length of the first production data is 4.95m, the diameter is 11mm, and the oxygen content is 5ppm. The first standard range is The first deviation information can be obtained by subtracting the length, diameter and oxygen content in the first production data from the length, diameter and oxygen content in the first standard range:

[0102]

[0103] S404, adjusting the first process parameter based on the first deviation information; determining difference information based on the first process parameter and the adjusted first process parameter; wherein the difference information is used to indicate the difference between the first process parameter before adjustment and the first process parameter after adjustment.

[0104] Exemplarily, adjusting the first process parameter based on the first deviation information may be adjusting the first process parameter by increasing or decreasing the first process parameter according to the size and direction of the deviation between the first production data and the first standard range. For example, if the length of the oxygen-free copper rod is too short, it may be necessary to increase the stretching speed or reduce the tension to increase the length.

[0105] Exemplarily, determining the difference information based on the first process parameter and the adjusted first process parameter may be calculating the difference or ratio between the first process parameter before and after the adjustment. For example, when the first process parameter includes temperature, pressure, tension, and speed, the difference information is: Among them, ΔT is the temperature difference between the first process parameters before and after adjustment, ΔP is the pressure difference between the first process parameters before and after adjustment, ΔF is the tension difference between the first process parameters before and after adjustment, and ΔV is the speed difference between the first process parameters before and after adjustment.

[0106] S405, when the difference information does not satisfy the first condition, the state value of the first process parameter is changed to the first state value, and the current production link is controlled to continue production; when the difference information satisfies the first condition, the state value of the first process parameter is changed to the second state value; wherein the first condition is used to indicate that the first process parameter has never been adjusted or the adjustment request of the first process parameter is not recorded as the first process parameter being adjusted.

[0107] It can be understood that the first state value is used to reflect that the first process parameter is currently adjusted (for example, the state value is "V1"), and the second state value is used to reflect that the first process parameter is currently not adjusted (for example, the state value is "V2").

[0108] Exemplarily, when the difference information does not meet the first condition, the oxygen-free copper rod production control equipment maintains the operating state of the oxygen-free copper rod production equipment unchanged, and updates the state value of the first process parameter, changing the state value of the first process parameter to the first state value; when the difference information meets the first condition, the oxygen-free copper rod production control equipment changes the state value of the first process parameter to the second state value.

[0109] Optionally, see Figure 3 S405, when the difference information does not meet the first condition, the state value of the first process parameter is changed to the first state value, and before the current production link is controlled to continue production, the oxygen-free copper rod production control method also includes:

[0110] S40501, determining a difference score based on the difference information; wherein the difference score is an indicator for quantitatively evaluating the degree of difference between the first process parameter before adjustment and the first process parameter after adjustment.

[0111] For example, the difference information may be standardized and normalized, and different types of data in the difference information are assigned corresponding weights according to the importance or influence of the data in the difference information (including at least one of the temperature difference, pressure difference, tension difference and speed difference), and the difference score is determined by weighted average. For example, when the first process parameter includes temperature, pressure, tension and speed, the difference information is: According to the weights of different types of data in the difference information, 0.4*10+0.3*2+0.1*5+0.1*2=5.3 is calculated, and the difference score is 5.3 (points).

[0112] S40502, determining whether the difference score exceeds a preset threshold.

[0113] It can be understood that the preset threshold is that the difference score does not exceed a preset specified value. The preset specified value can be set by ordinary technicians in this field according to actual needs and is not limited here.

[0114] For example, a reasonable preset threshold can be determined based on historical data and industry standards. For example, the preset threshold is set to 5 points, the difference score range is 0-10 points, and it is determined whether the difference score exceeds 5 points.

[0115] S40503: If the difference score does not exceed the preset threshold, determine that the difference information meets the first condition.

[0116] For example, when the difference score does not exceed a preset threshold, it can be considered that the difference between the first process parameter before adjustment and the first process parameter after adjustment is within an acceptable range, and it is determined that the difference information satisfies the first condition.

[0117] S40504: If the difference score exceeds a preset threshold, determine that the difference information does not satisfy the first condition.

[0118] For example, when the difference score exceeds a preset threshold, it indicates that the process parameters before and after the adjustment are greatly different, which may have a significant impact on the quality of the oxygen-free copper rod, and it is determined that the difference information does not meet the first condition.

[0119] Through the above steps S40501 to S40504, based on the quantitative evaluation of the difference information, the degree of change of the first process parameter before and after the adjustment is accurately measured. As a key indicator, the difference score can objectively reflect the degree of difference before and after the adjustment, thereby assisting in judging whether the adjustment has achieved the expected effect. This process not only improves the accuracy and controllability of process parameter adjustment, but also provides strong support for the continuous optimization of production processes.

[0120] S406: If the first production data is within the first standard range, the current production link is controlled to continue production, and the state value of the first process parameter is changed to the second state value.

[0121] Exemplarily, the operating state of the oxygen-free copper rod production equipment may be kept unchanged, while the state value of the first process parameter is updated and changed to the second state value.

[0122] S407 , determining whether the first process parameter is adjusted according to the state value of the first process parameter.

[0123] Exemplarily, whether the first process parameter is adjusted may be determined based on whether the checked state value is a first state value (eg, the state value is “ V1 ”) or a second state value (eg, the state value is “ V2 ”).

[0124] Through the above steps S401 to S407, by continuously monitoring the production data and process parameters, it is ensured that the production quality of the oxygen-free copper rod meets the preset standards. Once it is found that the production data does not meet the standards, the production is immediately stopped and adjusted to avoid the continued production of unqualified products. The first process parameter is accurately adjusted according to the first deviation information, and the adjustment effect is evaluated to ensure that the adjusted first process parameter can meet the production requirements. Determine whether the first process parameter has been actually adjusted based on the state value of the first process parameter, thereby providing an important basis for subsequent production analysis and optimization. Through the automated and intelligent adjustment process, manual intervention and downtime are reduced, and production efficiency is improved.

[0125] Optionally, see Figure 4 , S407, determining whether the first process parameter is adjusted according to the state value of the first process parameter, including:

[0126] S4071: If the state value of the first process parameter is the first state value, it is determined that the first process parameter is adjusted.

[0127] Exemplarily, when the oxygen-free copper rod production control equipment determines that the state value of the first process parameter is the first state value, it is considered that the first process parameter is adjusted.

[0128] S4072: If the state value of the first process parameter is the second state value, it is determined that the first process parameter is not adjusted.

[0129] Exemplarily, when the oxygen-free copper rod production control equipment determines that the state value of the first process parameter is the second state value, it is considered that the first process parameter has not been adjusted.

[0130] Through the above steps S4071 to S4072, it is possible to accurately determine whether the first process parameter has been adjusted according to the state value of the first process parameter, and take corresponding measures according to the determination result to ensure the stability of the production process and product quality. The production process continues to operate under careful monitoring, which helps to improve production efficiency, reduce production costs, and enhance the company's control over the production process.

[0131] In one possible implementation, see Figure 5 S400, when it is determined according to the state value of the first process parameter that the first process parameter is adjusted, determining second production data based on the first production data and the second process parameter, including:

[0132] S410, when it is determined that the first process parameter is adjusted according to the state value of the first process parameter, preprocessing the first production data and the second process parameter obtained in real time; wherein the preprocessing includes removing abnormal values ​​and noise and performing normalization processing.

[0133] Exemplarily, when it is determined that the first process parameter is adjusted based on the state value of the first process parameter, abnormal values ​​of the first production data and the second process parameter that may be caused by sensor failure or human operating error are cleaned, and possible noise is removed, and the data after removing the abnormal values ​​and noise is normalized (these data are scaled to a specific range).

[0134] S420, inputting the preprocessed first production data and the second process parameters into a standard model for prediction to obtain second production data.

[0135] It can be understood that the standard model is trained based on historical data and can accurately reflect the input-output relationship in the production process.

[0136] Exemplarily, after the pre-processed first production data and the second process parameters are input into the standard model, the standard model outputs the second production data of the oxygen-free copper rod.

[0137] Through the above steps S410 to S420, when it is confirmed that the first process parameter is adjusted, the second production data can be predicted and determined through the standard model based on the preprocessed first production data and the second process parameter, thereby providing strong support for the optimization and control of the production process.

[0138] Optionally, see Figure 6 , S420, inputting the pre-processed first production data and the second process parameters into the standard model for prediction to obtain the second production data, including:

[0139] S421, selecting characteristic data from historical data; wherein the historical data includes historical production records and quality inspection reports of oxygen-free copper rods, and the characteristic data includes process parameters, length, diameter and oxygen content of each production link in the production process of the oxygen-free copper rods.

[0140] For example, when selecting characteristic data, priority may be given to parameters that have the greatest impact on the quality of the oxygen-free copper rod, such as length, diameter, oxygen content, and process parameters.

[0141] S422, according to the feature data, assigning different weights to different feature data to obtain feature vectors.

[0142] It can be understood that a feature vector is a vector containing all feature data and their corresponding weights.

[0143] Exemplarily, according to the importance of different characteristic data for predicting the production data of oxygen-free copper rod in the next link, weights are assigned to the characteristic data of the corresponding link to obtain a characteristic vector. For example, the characteristic vector is [6×0.2, 10×0.15, 10×0.1, 1200×0.25, 50×0.1, 2000×0.1, 10×0.1], that is, [length (m), diameter (mm), oxygen content (ppm), temperature (°C), pressure (MPa), tension (N)] multiplied by the corresponding weights respectively.

[0144] S423, taking the feature vector as input, training the initial model.

[0145] It can be understood that the initial model is an untrained or only preliminarily trained model.

[0146] Exemplarily, the initial model may be a random forest model, and the feature vectors may be used as training data sets to train the initial model.

[0147] S424, verifying the trained initial model according to a cross-validation method to obtain a standard model. The cross-validation method is to train and test the initial model by repeatedly using a subset of feature data to predict the performance of the initial model.

[0148] It can be understood that the subset of feature data is achieved by dividing the original feature data set into multiple non-overlapping parts (for example, K subsets in K-fold cross validation).

[0149] For example, a 5-fold cross validation may be used to divide the original feature data set into 5 subsets, one of which is used as a test set, and the remaining 4 subsets are used as training sets for 5 iterations. The results of the 5 iterations are averaged to obtain an overall performance evaluation of the model and determine the standard model.

[0150] S425, inputting the preprocessed first production data and the second process parameters into the standard model for prediction.

[0151] For example, the preprocessed first production data and the second process parameter may be combined into a new feature vector, which is then input into the standard model for prediction.

[0152] [length (L_A), diameter (D_A), oxygen content (O_A), temperature (T_B), pressure (P_B), tension (F_B)], where the production data of the current production link A can be a length of 4.95m, a diameter of 11mm, and an oxygen content of 10ppm; the process parameters of the next link B of the current production link can be a temperature of 800℃, a pressure of 50MPa, and a tension of 100N.

[0153] S426, obtaining second production data according to the standard model output.

[0154] Exemplarily, the standard model may make predictions based on the input feature vector and output the prediction results as the second production data.

[0155] Through the above steps S421 to S426, historical data and machine learning technology can be used to establish an accurate prediction model for oxygen-free copper rod production data. The model has good generalization ability and practical application value, thereby providing strong support for quality control and process optimization in the production process.

[0156] S500: When it is determined based on the second production data that the production quality of the oxygen-free copper rod in the next step is unqualified, adjust the second process parameter.

[0157] Exemplarily, when it is determined based on the second production data that the production quality of the oxygen-free copper rod in the next link is unqualified, the production equipment of the oxygen-free copper rod may be controlled to adjust the second process parameter.

[0158] In one possible implementation, see Figure 7 S500, when it is determined based on the second production data that the production quality of the oxygen-free copper rod in the next link is unqualified, before adjusting the second process parameter, the oxygen-free copper rod production control method further includes:

[0159] S501, determining whether the second production data is within a preset second standard range.

[0160] It can be understood that judging whether the second production data is within the preset second standard range is judging whether the second production data is within a preset prescribed interval, and the preset prescribed interval can be set by ordinary technicians in the field according to actual needs and is not the only limitation here.

[0161] For example, the second production data can be determined to be completely within the preset second standard range only when the length, diameter and oxygen content in the second production data all meet their respective corresponding ranges. If any attribute does not meet any of its corresponding ranges, the second production data is determined to be not within the preset second standard range. For example, the second standard range is set as:

[0162] S502: If the second production data is within the second standard range, it is determined that the production quality of the oxygen-free copper rod in the next step is qualified.

[0163] Exemplarily, when the oxygen-free copper rod production control equipment determines that the second production data is within a preset second standard range, it is considered that the production quality of the oxygen-free copper rod in the next link is qualified.

[0164] S503, if the second production data is not within the second standard range, it is determined that the production quality of the oxygen-free copper rod in the next link is unqualified.

[0165] Exemplarily, when the oxygen-free copper rod production control equipment determines that the second production data is not within a preset second standard range, it is considered that the production quality of the oxygen-free copper rod in the next link is unqualified.

[0166] Through the above steps S501 to S503, real-time monitoring and rapid response to production quality can be achieved, so that problems in production can be discovered in time and corresponding measures can be taken to ensure that the produced oxygen-free copper rods meet the established quality requirements. This helps to improve the production efficiency and product quality of the enterprise and enhance its market competitiveness.

[0167] In one possible implementation, see Figure 8, S500, when it is determined based on the second production data that the production quality of the oxygen-free copper rod in the next link is unqualified, adjusting the second process parameter includes:

[0168] S510, when it is determined according to the second production data that the production quality of the oxygen-free copper rod in the next link is unqualified, determine second deviation information according to the second production data and the second standard range; wherein the second deviation information is used to indicate the size and direction of the deviation between the second production data and the second standard range.

[0169] For example, the difference or ratio between the second production data and the second standard range can be calculated, and whether it exceeds the highest value or the lowest value of the second standard range can be marked. For example, the second production data has a length of 5.5m, a diameter of 9.5mm, and an oxygen content of 10ppm, and the second standard range is: Then the second deviation information is:

[0170] S520, adjusting the second process parameter according to the second deviation information.

[0171] For example, the second process parameter may be adjusted based on the size and direction of the deviation between the second production data and the second standard range. For example, if the length of the oxygen-free copper rod is too short, the drawing speed may need to be increased or the tension may need to be reduced to increase the length.

[0172] Through the above steps S510 to S520, it is possible to achieve a quick response and precise adjustment to the unqualified production quality of the oxygen-free copper rod in the next link. This helps to reduce the number of unqualified products, improve production efficiency and product quality, and thus bring greater economic benefits and market competitiveness to the enterprise.
