In its production process, the quality control of each link is directly related to the performance of the final product and market competitiveness.

[0003] In the prior art, in the production process of oxygen-free copper rod, the existing monitoring means relies on manual inspection and periodic sampling detection. This way is not only inefficient, but also difficult to realize real-time monitoring of the whole production process, and it is easy to miss the key quality fluctuation point. Due to the limitation of monitoring and detection means, it is difficult to find the quality problems in the production site in time. Even if it is found, it often takes a long time to analyze the causes and solve them, which further aggravates the fluctuation of product quality and affects the production efficiency. Therefore, there are problems of low efficiency, difficult to find and solve quality problems in time in the production process of oxygen-free copper rod. SUMMARY

[0070] As used in the specification and in the claims, the term “if’ can be interpreted as meaning “when” or “upon” or “in response to a determination” or “in response to a detection” depending on the context. Similarly, the phrase “if it is determined” or “if [a described condition or event] is detected” can be interpreted as meaning “upon a determination” or “in response to a determination” or “upon a detection of [a described condition or event]” or “in response to a detection of [a described condition or event]” depending on the context.

[0071] In addition, in the description and the accompanying claims of the application, the terms “first”, “second”, “third”, etc. are used only to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0072] Reference in the specification to “one embodiment” or “some embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrase “in one embodiment” or “in some embodiments” in various places in the specification are not necessarily all referring to the same embodiment, although it can. The terms “including,” “containing,” “having,” and variations thereof are meant to encompass the terms “including but not limited to” unless otherwise indicated.

[0073] In the related art, in the production process of oxygen-free copper rods, the existing monitoring means relies on manual inspection and periodic sampling detection. This way is not only inefficient, but also difficult to realize real-time monitoring of the whole production process, and it is easy to miss the key quality fluctuation point. Due to the limitations of monitoring and detection means, it is difficult to discover the quality problems in the production site in time. Even if it is discovered, it often takes a long time to analyze the causes and solve them, which further aggravates the fluctuation of product quality and affects the production efficiency. Therefore, there are problems of low efficiency, difficult to discover and solve quality problems in time in the production process of oxygen-free copper rods.

[0074] To solve the above problems, the embodiment of the present application provides a method, system and device for producing and controlling oxygen-free copper rods. In the method, first production data and first process parameters of the oxygen-free copper rods in the current production link are obtained, the state value of the first process parameters is determined, and second process parameters of the oxygen-free copper rods in the next link of the current production link are obtained. The first production data includes the length, diameter and oxygen content of the oxygen-free copper rods in the current production link. By obtaining the length, diameter and oxygen content of the oxygen-free copper rods, the quality of the oxygen-free copper rods in each production link can be accurately determined. In the case that the first process parameters are adjusted according to the state value of the first process parameters, the second production data is determined based on the first production data and the second process parameters. In the case that the production quality of the oxygen-free copper rods in the next link is determined to be unqualified based on the second production data, the second process parameters are adjusted. Therefore, the method for producing and controlling oxygen-free copper rods provided by the embodiment of the present application monitors the adjustment of the process parameters by using the state value. Once the process parameters are detected to be adjusted, the production data of the next link is predicted and determined based on the new production data and the process parameters of the subsequent link, so that the quality problem can be found in time. Once the quality problem is found, the system can trigger the adjustment mechanism in time to solve the quality problem and ensure the quality of the oxygen-free copper rods in the subsequent production link. By real-time monitoring and automatic adjustment of the process parameters, the production process can be quickly responded to the changes, and the production stagnation and delay caused by the untimely or misjudged manual intervention can be avoided, thereby significantly improving the production efficiency.

[0075] The method for producing and controlling oxygen-free copper rods provided by the embodiment of the present application can be applied to an oxygen-free copper rod production and control device. At this time, the oxygen-free copper rod production and control device is the execution subject of the method for producing and controlling oxygen-free copper rods provided by the embodiment of the present application, and the specific type of the oxygen-free copper rod production and control device is not limited in the embodiment of the present application.

[0076] The oxygen-free copper rod production control device can be in communication connection with the production devices of each production link of the oxygen-free copper rod. For example, the oxygen-free copper rod production control device can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a handset, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), a desktop computer, a smart large screen, a smart television, a handheld device with wireless communication function, a computing device or other processing device 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, and the like, but is not limited thereto.

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

[0078] Figure 1 A schematic flowchart of the oxygen-free copper rod production control method provided by the embodiments of the present application is shown, and the oxygen-free copper rod production control method comprises:

[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 take-up, the first production data comprises the length, diameter and oxygen content of the oxygen-free copper rod in the current production link, the first process parameters are process parameters preset by the production device of the oxygen-free copper rod in the current production link, and the first process parameters comprise 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, obtaining the first production data of the oxygen-free copper rod in the current production link can be real-time monitoring the length of the oxygen-free copper rod on the production line by a laser ranging sensor, real-time monitoring the diameter of the oxygen-free copper rod on the production line by a laser displacement sensor, and real-time monitoring the oxygen content of the oxygen-free copper rod on the production line by an electrochemical oxygen sensor. Of course, the length, diameter and oxygen content of the oxygen-free copper rod can also be directly received by manual input.

[0082] Exemplarily, the first process parameter of the oxygen-free copper rod in the current production link can be a set parameter of a production device of the oxygen-free copper rod directly read by the oxygen-free copper rod production management and control device. Of course, the first process parameter of the oxygen-free copper rod can also be directly received by manual input.

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

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

[0085] By determining the state value of the first process parameter, the adjustment of the first process parameter is monitored by using the state value. Once it is detected that the first process parameter is adjusted, the production data of the next link is predicted and determined based on the new first production data and the process parameter of the subsequent link, so that the quality problem can be found in time.

[0086] S300, acquire 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 a production device 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 which is processed in the current production link and then output after further processing in the next production link.

[0088] Exemplarily, the oxygen-free copper rod production management and control device can query the process parameter preset by the production device of the oxygen-free copper rod in the next link.

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

[0090] It can be understood that after the first process parameter is determined to be 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] Exemplarily, whether the first process parameter is adjusted can be determined according to whether the state value is the first state value (for example, the state value is “V1”) or the second state value (for example, 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] Exemplarily, the second production data can be predicted according to the first production data and the second process parameter by using a random forest model. For example, an initial random forest model is trained, and after the performance of the random forest model is verified to be qualified by a cross-validation method, the second production data is output by inputting the first production data and the second process parameter into the random forest model.

[0093] In a possible implementation, please refer to Figure 2 , S400, in a case where 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 management and control method further comprises:

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

[0095] It can be understood that determining whether the first production data is within the preset first standard range is to determine whether the first production data is within a preset specified interval, which can be set by a person skilled in the art according to actual needs, and is not limited herein.

[0096] Exemplarily, the first production data can be determined to be within the preset first standard range only when the length, the diameter and the oxygen content in the first production data all meet their respective corresponding ranges. If any one of the length, the diameter and the oxygen content does not meet the corresponding range, it is determined that the first production data is 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, the oxygen-free copper rod production management and control device can send a stop signal to the production equipment of the oxygen-free copper rod to control the current production link to stop production in a case where it is determined that the first production data is not within the first standard range.

[0100] S403, first deviation information is determined 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] Exemplarily, 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 it is marked whether the highest value or the lowest value exceeds the first standard range. For example, the length of the first production data is 4.95 m, the diameter is 11 mm, and the oxygen content is 5 ppm, and the first standard range is The length, diameter, and oxygen content of the first production data are subtracted from the length, diameter, and oxygen content of the first standard range, respectively, to obtain the first deviation information:

[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 adjusted first process parameter.

[0104] Exemplarily, adjusting the first process parameter based on the first deviation information can be 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, the length of the oxygen-free copper rod is low, and the stretching speed or the tension may need to be increased or decreased to increase the length.

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

[0106] S405, in the case that the difference information does not satisfy the first condition, changing the state value of the first process parameter to the first state value and controlling the current production link to continue production; in the case that the difference information satisfies the first condition, changing the state value of the first process parameter 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"). 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, in the case that the difference information does not satisfy the first condition, the oxygen-free copper pole production control device keeps the running state of the oxygen-free copper pole production equipment unchanged, and updates the state value of the first process parameter to the first state value; in the case that the difference information satisfies the first condition, the oxygen-free copper pole production control device updates the state value of the first process parameter to the second state value.

[0109] Optionally, referring to Figure 3 , S405, in the case that the difference information does not satisfy the first condition, the state value of the first process parameter is updated to the first state value, and before the current production link continues to produce, the oxygen-free copper pole production control method further comprises:

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

[0111] Exemplarily, the difference information can be standardized and normalized, and different types of data in the difference information are given corresponding weights according to the importance or influence degree of the data (including at least one of the difference values of temperature, pressure, tension and speed) in the difference information, and the difference score is determined by the weighted average method. 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, which can be set by a person skilled in the art according to actual needs, which is not limited herein.

[0114] Exemplarily, a reasonable preset threshold can be determined according to historical data and industry standards. For example, the preset threshold is set to 5 points, the value range of the difference score 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, it is determined that the difference information satisfies the first condition.

[0116] Exemplarily, when the difference score does not exceed the 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 the preset threshold, determining that the difference information does not satisfy the first condition.

[0118] Exemplarily, when the difference score exceeds the preset threshold, it indicates that the difference between the process parameters before and after adjustment is large, which may have a significant impact on the quality of oxygen-free copper rods. Therefore, it is determined that the difference information does not satisfy 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 adjustment is accurately measured. The difference score as a key indicator can objectively reflect the degree of difference before and after adjustment, thereby assisting in determining whether the adjustment achieves the expected effect. This process not only improves the accuracy and controllability of process parameter adjustment, but also provides strong support for continuous optimization of production process.

[0120] S406, if the first production data is within the first standard range, controlling the current production link to continue production, and changing the state value of the first process parameter to the second state value.

[0121] Exemplarily, the running state of the production equipment for oxygen-free copper rods can be kept unchanged, and the state value of the first process parameter is updated 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 can be determined according to whether the state value is the first state value (for example, the state value is "V1") or the second state value (for example, the state value is "V2").

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

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

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

[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, it can be considered that the first process parameter is not adjusted when the oxygen-free copper rod production control equipment determines that the state value of the first process parameter is the second state value.

[0130] Through the above steps S4071 to S4072, it can be accurately judged whether the first process parameter has been adjusted according to the state value of the first process parameter, and corresponding measures are taken according to the judgment result, so as to ensure the stability of the production process and the product quality. The production link continues to run under careful monitoring, which helps to improve production efficiency, reduce production cost, and enhance the control ability of enterprises on the production process.

[0131] In a possible implementation, please refer to Figure 5 S400, in the case where it is determined that the first process parameter is 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, comprising:

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

[0133] Exemplarily, in the case where it is determined that the first process parameter is adjusted according to the state value of the first process parameter, the abnormal values of the first production data and the second process parameter caused by sensor failure or human operation error can be cleaned up, and the noise that may exist can be removed, and the data after removing the abnormal values and the noise is normalized (scaling these data to a specific range).

[0134] S420, the preprocessed first production data and the second process parameter are input into a standard model for prediction to obtain the 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, the second production data of the oxygen-free copper rod can be obtained by inputting the preprocessed first production data and the second process parameters into the standard model.

[0137] Through the steps S410-S420, the second production data can be predicted and determined by the standard model based on the preprocessed first production data and the second process parameters in the case that the first process parameters are adjusted, which provides strong support for the optimization and control of the production process.

[0138] Optionally, referring to Figure 6 , S420, the preprocessed first production data and the second process parameters are input into the standard model for prediction to obtain the second production data, comprising:

[0139] S421, selecting feature data from historical data; wherein the historical data comprises historical production records and quality detection reports of the oxygen-free copper rod, and the feature data comprises process parameters, length, diameter and oxygen content of each production link in the production process of the oxygen-free copper rod.

[0140] Exemplarily, when selecting the feature data, those parameters which have the greatest impact on the quality of the oxygen-free copper rod are given priority, for example, length, diameter, oxygen content and process parameters.

[0141] S422, according to the feature data, different weights are assigned to different feature data to obtain a feature vector.

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

[0143] Exemplarily, the feature vector can be obtained by assigning weights to the feature data of the corresponding link according to the importance of different feature data for predicting the production data of the next link of the oxygen-free copper rod, for example, the feature vector is [6x0.2, 10x0.15, 10x0.1, 1200x0.25, 50x0.1, 2000x0.1, 10x0.1], i.e. [length (m), diameter (mm), oxygen content (ppm), temperature (℃), pressure (MPa), tension (N)] multiplied by the corresponding weight.

[0144] S423, the feature vector is taken as input to train the initial model.

[0145] It can be understood that the initial model is a model that has not been trained or has only been trained initially.

[0146] Exemplarily, the initial model can be a random forest model, and the feature vector can be taken as a training data set 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 subsets of the feature data to predict the performance of the initial model.

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

[0149] For example, 5-fold cross-validation can be used, and the original feature data set is divided into 5 subsets. One of the 5 subsets is used as the test set, and the remaining 4 subsets are used as the training set for 5 iterations. The results of the 5 iterations are averaged to obtain the overall performance evaluation of the model, and the standard model is determined.

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

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

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

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

[0154] For example, the standard model can predict according to the input feature vector and output the prediction result as the second production data.

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

[0156] S500, in the case that the production quality of the oxygen-free copper rod in the next link is determined to be unqualified based on the second production data, adjusting the second process parameter.

[0157] Exemplarily, the production equipment of the oxygen-free copper rod can be controlled to adjust the second process parameter in a case where 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.

[0158] In a possible implementation, referring to Figure 7 , S500, in a case where 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 the second process parameter is adjusted, the oxygen-free copper rod production management and control method further includes:

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

[0160] It can be understood that whether the second production data is within the preset second standard range is to judge whether the second production data is within a preset specified interval, which can be set by a person skilled in the art according to actual needs, and is not uniquely limited here.

[0161] Exemplarily, it can be determined that the second production data is completely within the preset second standard range only when the length, diameter and oxygen content in the second production data all meet a range corresponding to each of them. If any attribute does not meet the range corresponding to it, it is determined that the second production data is 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 link is qualified.

[0163] Exemplarily, when the oxygen-free copper rod production management and control equipment determines that the second production data is within the 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 management and control equipment determines that the second production data is not within the 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 the production quality can be realized, so that problems in production can be found in time and corresponding measures can be taken to ensure that the produced oxygen-free copper rod meets the established quality requirements. This helps to improve the production efficiency and product quality of enterprises and enhance market competitiveness.

[0167] In a possible implementation, referring to Figure 8S500, in a case where 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, including:

[0168] S510, in a case where 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, determining 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] Exemplarily, the difference or ratio between the second production data and the second standard range can be calculated, and it is marked whether the highest value or the lowest value exceeds the second standard range. For example, in the second production data, the length is 5.5m, the diameter is 9.5mm, and the oxygen content is 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] Exemplarily, the second process parameter can be adjusted according to the size and direction of the deviation between the second production data and the second standard range. For example, the length of the oxygen-free copper rod is low, and the stretching 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, the unqualified production quality of the oxygen-free copper rod in the next link can be quickly responded and accurately adjusted. 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.
