These drawings and textual descriptions are not intended to limit the scope of the concept of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0081] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. The following description is with reference to the drawings, in which like numerals represent like elements, unless otherwise specified. The embodiments described in the following exemplary embodiments are not representative of all embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0082] The following explains some of the terms involved in the present application:

[0083] Wire rod: Wire rod generally refers to hot-rolled round steel with a diameter of 5-22 mm or shaped steel with a cross section equivalent to this, which is delivered in a coiled form, and is also commonly known as coil.

[0084] Wire rod: Wire rod generally refers to hot-rolled round steel with a diameter of 5-22 mm or shaped steel with a cross section equivalent to this, which is delivered in a coiled form, and is also commonly known as coil.

[0085] Coiling: Coiling refers to the operation process of collecting the wire or bar coils wound by the spinning machine and arranging them into a shape and state convenient for transportation and subsequent processing.

[0086] Coiling: In the field of high-speed wire processing, "coiling" refers to the process of processing steel into a disc or coil shape by a specific device and the finished product state.

[0087] Coil: Refers to the spiral-shaped finished product or semi-finished product after rolling of steel, which is the basis for subsequent processing. The coil structure is more loose than the coiling structure.

[0088] After completing the spinning process and obtaining the shaped coil, the high-speed wire production line needs to transport the coil to the next process through a long-distance roller conveyor system. During the entire transportation process, the running speed of the roller and the temperature of the coil need to be accurately controlled to ensure coordination with the overall production rhythm and to ensure that the performance indicators of the coil meet the requirements.

[0089] Regarding the control of running speed, if the roller running speed is too fast, it may lead to uneven changes in coil temperature or premature termination of the temperature control process, affecting the quality of the coil. If the roller running speed is too slow in order to ensure uniform changes in coil temperature, it may lead to waste of transportation resources and affect the overall production rhythm.

[0090] The control of temperature requirements is even more stringent, and different types of coils often require different temperature control strategies. For example, if you want to form a wire with good plasticity and toughness, you need to adopt a slow cooling method to allow atoms inside the steel to have enough time to diffuse and rearrange, forming coarse grain structures such as pearlite and ferrite. If you want to form a wire with high strength, hardness, and wear resistance, you need to adopt a rapid cooling method to prevent atoms from fully diffusing, forming fine and dispersed structures such as martensite and bainite.

[0091] Current production lines are equipped with basic temperature control transportation systems that can achieve preliminary temperature control transportation of coils, but in actual operation, the adjustment accuracy of transportation speed is insufficient, and the response speed of the temperature control system is slow, resulting in large temperature fluctuations of the coil during transportation. These problems not only cause instability in the quality of the final product, with significant differences in performance parameters, but also lead to low transportation efficiency, causing valuable transportation resources to be underutilized and affecting the overall economic benefits of the production line.

[0092] The inventors have found that most of the existing transport systems adopt a preset control parameter mode for different types of wires. For example, for a certain type of wire, the corresponding transport speed parameter and temperature control parameter (for example, the operating frequency of the cooling fan) can be preset. When the actual transport of this type of wire is carried out, the transport system can be configured with the corresponding control parameters for temperature control transport. However, these parameters are calibrated offline through historical experience, and in the actual transport process, due to the batch of coils, the stability of the transport system itself, the external environment and other reasons, controlling according to the preset parameters will cause differences between the actual temperature control transport process and the ideal process. For example, due to the influence of the external environment, there can be a large difference between the actual temperature drop rate of the coil during transport and the expected temperature drop rate, resulting in differences in the performance of the final coil.

[0093] There are some transport systems that adjust parameters according to feedback from the actual transport process to make the transport speed and temperature change of the coil meet the requirements as much as possible. However, this transport method also has disadvantages. This transport method mostly adjusts parameters according to the detection parameters at the current time, and the parameter adjustment process and the response of the transport system have a lag, affecting the temperature control transport effect of the coil.

[0094] The inventors consider that if the detection parameters during the transport of the coil can be accurately predicted and the transport speed and temperature control parameters are adjusted according to the predicted detection parameters, the problem of lag in the response of the transport system in the parameter control process can be overcome, the control accuracy of the transport process of the coil can be improved, and the performance of the obtained coil can be improved. In view of this, the present application provides a wire transport system with a temperature control corridor, wherein the temperature control corridor provides a closed environment for the transport process to better isolate the external environment for temperature control transport. In addition, the transport system predicts multiple parameters in the future according to historical detection parameters (such as coil temperature, transport speed, etc.), and adjusts the control parameters of the temperature control corridor during the transport of the coil based on the predicted parameters. Through this implementation, the control parameters of the temperature control corridor can be adjusted predictively, the PID control of preposition-feedback can be realized, the problem of lag in the response of the transport system can be improved, and thus the control accuracy of the transport system in the transport process of the coil can be improved, the transport demand can be met, the energy consumption of transport can be reduced, and the quality of the coil can be improved.

[0095] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below through specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments.

[0101] The temperature control corridor 3 comprises a temperature control unit 31, a high-temperature transportation unit 32, a heat preservation unit 33, and a parameter acquisition unit 34.

The heat preservation unit 33 comprises a heat preservation wall 331, a first heat preservation door 332, and a second heat preservation door 333. The space between the heat preservation wall 331, the first heat preservation door 332, and the second heat preservation door 333 is a closed space when the first heat preservation door 332 and the second heat preservation door 333 are closed.

The specific implementation can refer to the prior art, which will not be described here.

[0113] Optionally, the control module 1 can include a user interaction interface, and obtain the winding instruction input by the user through the interaction interface; or the control module 1 can obtain the winding instruction sent by other devices; or the wire conveying system of the temperature-controlled corridor 3 includes a target coil detection assembly, and the control module 1 detects whether the coil is transported to the preset position by the conveying module 2 through the target coil detection assembly, and if it is determined that the target coil is transported to the preset position, it is determined that the winding instruction is obtained; or the control module 1 detects that the coil is transported to the preset position through the target coil detection assembly, and determines that the winding module 4 can perform winding processing on the next coil, and then determines that the winding instruction is obtained.

[0114] The above-mentioned other devices may, for example, be a user terminal such as a mobile phone, a tablet, a computer, a remote controller, etc. The above-mentioned target coil detection assembly may, for example, be an infrared detection assembly, which may, for example, be located at the above-mentioned preset position, and the control module 1 can determine whether the coil is transported to the preset position through the above-mentioned infrared detection assembly. The above-mentioned preset position may, for example, be a specific position in front of the winding module 4, which can be set by a person skilled in the art according to requirements.

[0115] The control module 1 may, for example, determine whether the winding module 4 can perform winding processing on the next coil through the detection signal fed back by the winding module 4. For example, the winding module 4 can include an infrared detection assembly, through which it is detected whether the winding module 4 has a coil that is being wound, and if not, a detection signal that the winding processing on the next coil can be performed is sent to the control module 1.

[0116] S102, according to the winding instruction, the winding module is controlled to wind the target coil to obtain a target coil.

[0117] In this step, the control module 1 controls the winding module 4 to wind the target coil according to the winding instruction to obtain a target coil, so that subsequent processing can be performed based on the winding state of the wire in the future, which is convenient for operation, transportation and storage.

[0118] The present application does not limit the way in which the control module 1 controls the winding module 4 to wind the target coil, which is related to the implementation of the winding module 4. A person skilled in the art can configure it according to requirements. For example, the winding module 4 can include a winding drum, and the control module 1 controls the winding drum in the winding module 4 to wind, and the specific implementation can refer to the prior art, which will not be described here.

[0119] S103, control the conveying module to convey the target coil into the first heat preservation door 332 and use the high-temperature conveying unit to convey the target coil.

[0120] In this step, the control module 1 controls the transportation module 2 to transport the target coil into the first temperature insulation door 332 and use the high-temperature transportation unit 32 to transport the target coil, so that the target coil can be transported in a concentrated and accurate temperature control manner.

[0121] Optionally, before the transportation module 2 transports the target coil into the first temperature insulation door 332, the first temperature insulation door 332 may, for example, be in a closed state, and when the control module 1 controls the transportation module 2 to transport the target coil into the first temperature insulation door 332, the first temperature insulation door 332 is opened so that the target coil can enter. After the transportation module 2 transports the target coil into the first temperature insulation door 332, the first temperature insulation door 332 is closed. Through this implementation manner, the target coil can be isolated from the external environment as much as possible during temperature control transportation, the control difficulty of the wire transportation process is reduced, the parameter control precision in the transportation process is further improved, and the temperature control transportation effect is improved.

[0122] S104, real-time acquisition and storage of detection parameters related to the target coil in the temperature control corridor by using the parameter acquisition unit 34.

[0123] In this step, the control module 1 uses the parameter acquisition unit 34 to acquire the detection parameters related to the target coil in the temperature control corridor 3 when the target coil is transported in the temperature control corridor 3, so that the future detection parameters, temperature drop rate and other transportation states of the target coil can be predicted.

[0124] The above-mentioned detection parameters related to the target coil may, for example, include one or more of the temperature of the target coil, the air pressure / air volume near the target coil, the transportation speed of the target coil, the humidity near the target coil, the weight of the target coil, and the like.

[0125] The parameter acquisition unit 34 can acquire the above-mentioned detection parameters periodically, or acquire the above-mentioned detection parameters at a fixed time, or use a combination of periodic acquisition and fixed-time acquisition.

[0126] For example, the parameter acquisition unit 34 can acquire the detection parameters every 2 minutes; or the parameter acquisition unit 34 can acquire the detection parameters in the temperature control corridor 3 when the unit of time is 3, 6, or 9; or the parameter acquisition unit 34 can acquire the detection parameters once when the target coil just enters the first temperature insulation door 332 completely, and acquire the detection parameters in the temperature control corridor 3 periodically during the transportation of the target coil between the first temperature insulation door 332 and the second temperature insulation door 333.

[0127] The parameter acquisition frequency of different detection parameters can be the same or different, and is specifically determined according to the detection parameters to be acquired. For example, if the parameter acquisition unit 34 includes a temperature sensor and a speed detector, the control module 1 can control the temperature sensor to acquire the temperature every 1 minute and control the speed detector to acquire the transportation speed every 2 minutes.

[0128] S105, acquiring a target parameter of the target coil during transportation of the target coil in the temperature-controlled corridor.

[0129] The target parameter is an ideal performance parameter of the target coil during transportation of the target coil in the temperature-controlled corridor 3. For example, the target parameter can include one or more of a target temperature drop rate of the target coil, a target transportation time, a target transportation rate, a target temperature, and a temperature variance / standard deviation of the target coil at the same coil. The above is only an example, and the application does not limit whether the target parameter further includes other items.

[0130] The specific value of the target parameter can be, for example, offline calibrated by a worker, or determined according to experience, or determined by consulting literature, and the application does not limit this.

[0131] The target temperature drop rate refers to an ideal temperature drop rate. The target transportation time refers to an ideal transportation time of the target coil in the temperature-controlled corridor 3. The target transportation rate refers to an ideal transportation rate of the target coil in the temperature-controlled corridor 3. The target temperature refers to an ideal temperature of the target coil when being transported to different positions in the temperature-controlled corridor 3. The temperature variance / standard deviation of the target coil at the same coil refers to the temperature variance / standard deviation of different positions of the target coil at the same coil. The different target parameters described above can each be a numerical value or an interval, and the application does not limit this.

[0132] In one possible implementation, the control module 1 can acquire the target parameter input by a user. For example, the control module 1 can include a user interaction interface, according to which the target parameter input by the user is acquired.

[0133] In another possible implementation, the control module 1 can first acquire the type of the target coil; and then determine the target parameter of the target coil according to the type of the target coil.

[0134] The control module 1 can directly acquire the type of the target disk volume input by the user, or can acquire the type of the target disk volume input by other devices, for example, a computer, a mobile phone, a tablet, a remote controller, etc. The control module 1 can store a mapping relationship between the type of the target disk volume and the target parameter, for example. After the control module 1 acquires the type of the target disk volume, the target parameter of the target disk volume is determined according to the type of the target disk volume and the mapping relationship. In this way, the target parameter can be determined only by acquiring the type of the target disk volume without manual input by the user, so that the operation mode is simplified, the operation convenience is improved, and the user experience is improved.

[0135] It should be noted that the step can be performed before steps S101-S104, simultaneously with any one of steps S101-S104, or after steps S101-S104 are performed, which is not limited in the present application.

[0136] S106, according to the detection parameter in the time period from the first historical time to the current time, predicting the estimated parameter corresponding to the target parameter in the time period from the current time to the first future time.

[0137] The time period from the first historical time to the current time is the historical time period, and on this basis, the present application does not limit which time the first historical time refers to, which can be set by the person skilled in the art as needed. It should be understood that the time period from the first historical time to the current time includes the current time.

[0138] The time period from the current time to the first future time is the future time period, and on this basis, the present application does not limit which future time the first future time refers to, which can be set by the person skilled in the art as needed. It should be understood that the time period from the current time to the first future time does not include the current time.

[0139] The estimated parameter corresponds to the target parameter, that is, the parameter items included in the target parameter and the parameter items included in the estimated parameter are the same. For example, if the target parameter includes the target temperature drop rate of the target disk volume, the target transportation time, and the target intra-circle temperature variance / standard deviation of the target disk volume, the estimated parameter also includes the target temperature drop rate of the target disk volume, the target transportation time, and the target intra-circle temperature variance / standard deviation of the target disk volume. Similarly.

[0140] Optionally, the control module 1 can first predict the detection parameter related to the target disk volume in the time period from the current time to the first future time according to the detection parameter in the time period from the first historical time to the current time. Then, the estimated parameter is determined according to the detection parameter related to the target disk volume in the time period from the current time to the first future time.

[0141] Alternatively, the control module 1 can predict the estimated parameter directly according to the detection parameter in the time period between the first historical time and the current time, without predicting the detection parameter of the target coil in the time period between the current time and the first future time.

[0142] Optionally, the control module 1 can determine the estimated parameter according to the detection parameter in the time period between the first historical time and the current time, and the mapping relationship between the detection parameter and the estimated parameter. For example, the control module 1 can store the mapping relationship between the detection parameter and the estimated parameter. After the control module 1 obtains the detection parameter in the time period between the first historical time and the current time, the control module 1 can determine the estimated parameter according to the mapping relationship.

[0143] Optionally, the control module 1 can predict the estimated parameter corresponding to the target parameter in the time period between the current time and the first future time according to the detection parameter in the time period between the first historical time and the current time, and using a parameter prediction model.

[0144] For example, the control module 1 can input the detection parameter in the time period between the first historical time and the current time into the parameter prediction model, and output the estimated parameter corresponding to the target parameter in the time period between the current time and the first future time using the parameter prediction model.

[0145] Alternatively, the control module 1 can input the detection parameter in the time period between the first historical time and the current time into the parameter prediction model, and output the predicted detection parameter of the target coil in the time period between the current time and the first future time using the parameter prediction model. Then, the control module 1 can calculate the estimated parameter corresponding to the target parameter in the time period between the current time and the first future time according to the predicted detection parameter of the target coil in the time period between the first historical time and the current time. It should be noted that in this implementation, the detection parameter of the target coil in the time period between the current time and the first future time and the estimated parameter corresponding to the target parameter in the time period between the current time and the first future time have a corresponding relationship. The control module 1 can calculate the estimated parameter according to the detection parameter of the target coil in the time period between the current time and the first future time.

[0146] For example, the detection parameter of the target coil in the time period between the current time and the first future time can include the predicted temperature of the target coil in the time period. The estimated parameter can include the predicted temperature drop rate of the target coil, for example. The control module 1 can calculate the predicted temperature drop rate of the target coil in the time period according to the temperature of the target coil in the time period. The specific calculation method can refer to the prior art, which will not be described here. Similarly.

[0147] The parameter prediction model can be trained based on any machine learning model with parameter prediction capability, for example. The machine learning model can be a neural network model, a Bayesian model, etc. The model prototype is only an example, and any model with parameter prediction capability can be used to train or debug the parameter prediction model.

[0148] It should be understood that the training method of the parameter prediction model used in different embodiments is different. For example, if the control module 1 uses the detection parameters in the time period from the first historical time to the current time as the input of the parameter prediction model, and uses the parameter prediction model to output the estimated parameters corresponding to the target parameters in the time period from the current time to the first future time, the training method of the parameter prediction model can be, for example, to use the detection parameters of other coils in the time period from the second historical time to the reference time as the input, and use the parameters corresponding to the target parameters in the time period from the reference time to the third future time as the label to train any machine learning model. The relative relationship between the second historical time and the current time is the same as the relative relationship between the first historical time and the current time. The relative relationship between the third future time and the current time is the same as the relative relationship between the first future time and the current time. The type of the other coil can be the same as that of the target coil. The specific training method of the parameter prediction model can refer to the prior art, which will not be described here.

[0149] If the control module 1 uses the detection parameters in the time period from the first historical time to the current time as the input of the parameter prediction model, and uses the parameter prediction model to output the predicted detection parameters of the target coil in the time period from the current time to the first future time. The training method of the parameter prediction model can be, for example, to use the detection parameters of other coils in the time period from the second historical time to the current time as the input, and use the detection parameters in the time period from the current time to the third future time as the label to train any machine learning model. The specific implementation can refer to the prior art, which will not be described here.

[0150] The historical detection parameters, the estimated parameters corresponding to the detection parameters in the time period from the second historical time to the reference time, or the detection parameters in the time period from the reference time to the third future time can be artificially configured, or can be obtained based on the parameter collection of the process of transporting the target coil, which is not limited in the present application.

[0151] Optionally, in some embodiments, the control model can predict the estimated parameter corresponding to the target parameter in the time period from the current time to the first future time based on the detection parameter in the time period from the first historical time to the current time according to the pre-built digital twin model. The application does not limit the building method of the digital twin model, and the specific implementation manner can refer to the prior art, which will not be described here.

[0152] Optionally, in some embodiments, the control module 1 can predict the estimated parameter corresponding to the target parameter in the time period from the current time to the first future time based on the detection parameter in the time period from the first historical time to the current time by using the parameter prediction model. In some embodiments, the control module 1 can predict the estimated parameter corresponding to the target parameter in the time period from the current time to the first future time based on the detection parameter in the time period from the first historical time to the current time and other data by using the parameter prediction model. The other data may, for example, include the control parameter in the time period from the first historical time to the current time. Through this implementation manner, the data basis for predicting the estimated parameter can be increased, and the prediction accuracy of the estimated parameter can be improved, and the accuracy of the finally obtained control parameter can be further improved, and the control accuracy of the control system provided by the application can be improved. It should be understood that in this implementation manner, the training method of the parameter prediction model needs to be adaptively adjusted according to the requirements, for example, if the prediction is based on the above-mentioned other data, the other data needs to be taken as one of the input data in the parameter prediction model training process, and the model needs to be trained.

[0153] S107, determining the control parameter of the temperature control corridor in the time period from the current time to the second future time according to the difference between the target parameter in the time period from the current time to the first future time and the estimated parameter corresponding to the target parameter in the time period from the current time to the first future time, and the control parameter of the temperature control corridor at the current time.

[0154] The second future time can refer to the same future time as the first future time, or can be different from the first future time, which is not limited by the application.

[0155] The difference mentioned here refers to the difference between the corresponding parameter items of the target parameter and the estimated parameter. There can be one or more differences. For example, if the target parameter includes target temperature drop rate, target transportation rate and target temperature holding time, and the estimated parameter includes estimated temperature drop rate, estimated transportation rate and estimated temperature holding time. The difference may, for example, include the difference between the target temperature drop rate and the estimated temperature drop rate, the difference between the target transportation rate and the estimated transportation rate, and the difference between the target temperature holding time and the estimated temperature holding time.

[0156] The control parameter refers to a parameter used to control the modules and components in the transportation system provided by the present application. The specific parameter items included in the control parameter and the specific implementation of the high-temperature transportation unit 32 and the temperature control unit 31 are related. For example, if the high-temperature transportation unit 32 includes an engine used to drive the high-temperature transportation unit 32 to transport, the control parameter may, for example, include the operating frequency of the engine; if the temperature control unit 31 includes a heating component, the control parameter may, for example, include the heating power of the heating component; if the temperature control unit 31 includes an air cooling component, the control parameter may, for example, include the operating frequency of the fan; if the temperature control unit 31 includes a water cooling component, the control parameter may, for example, include the operating frequency of the engine of the water cooling component.

[0157] Optionally, in one possible implementation, the control module 1 stores a mapping relationship between the difference, the control parameter of the temperature control corridor 3 at the current time, and the control parameter in the time period from the current time to the second future time. The control module 1 determines the control parameter in the time period from the current time to the second future time according to the difference, the control parameter of the temperature control corridor 3 at the current time, and the mapping relationship. The present application does not limit the mapping manner, which may, for example, be an interval mapping manner. For details, refer to the prior art, which will not be described here.

[0158] Optionally, in another possible implementation, if the difference is within the preset error range, the control parameter at the current time is taken as the control parameter in the time period from the current time to the second future time.

[0159] The present application does not limit the specific interval range of the above-mentioned preset error range, which can be set according to the needs of those skilled in the art. In this case, since the difference is within the preset error range, it proves that the current transportation process of the target coil meets the expectations, and the current control parameter meets the transportation needs, so the control parameter at the current time can be directly taken as the control parameter in the time period from the current time to the second future time.

[0160] If the difference is not within the preset error range, the control parameter at the current time is adjusted according to the difference, and the adjusted control parameter is taken as the control parameter in the time period from the current time to the second future time.

[0161] In the case of including multiple differences, the difference not within the preset error range may be that any one or more of the differences is not within the preset error range, or that all the differences are not within the preset error range.

[0162] Optionally, in this implementation, the control module 1 can adjust the control parameter at the current time according to the above difference value and the control parameter at the current time, in a PID tuning manner, or based on a loss function optimization algorithm, or a reinforcement learning method based on a large model. The specific implementation can refer to the prior art, which will not be described here.

[0163] It should be understood that the current time changes as time migrates, and the control module 1 performs steps S106 and S107 in real time according to the latest current time.

[0164] S108, according to the control parameter, controlling the high-temperature transportation unit and the temperature control unit in the time period from the current time to the second future time, until the high-temperature transportation unit transports the target coil out of the second heat preservation door 333, and obtains the target coil with stable mechanical performance parameters.

[0165] The mechanical performance parameters mentioned here may, for example, include high sorbite rate, high face reduction rate, low H content, tensile strength, etc.

[0166] For example, Figure 4 A cross-sectional structure diagram of a temperature control corridor provided in the present application is shown, which is a diagram of a temperature control unit 31 including a heating assembly 311 and a circulating fan 312. The cross-sectional structure diagram of the temperature control corridor 3 mentioned here is a cross-sectional structure diagram after cutting the temperature control corridor 3 along a direction perpendicular to the target coil transportation direction. It should be understood that, Figure 4 The cross-sectional position shown is the position including the heating assembly 311 and the circulating fan 312, and does not represent that every position of the temperature control corridor 3 includes the heating assembly 311 and the circulating fan 312. For example, Figure 4 As shown, if the temperature control unit 31 includes a heating assembly 311, the control parameter may, for example, include the heat power of the heating assembly 311, and the control module 1 may, for example, control the heating assembly 311 to perform heat compensation on the target coil according to the heat power, so as to realize precise temperature control and cooling of the target coil during transportation.

[0167] If the temperature control unit 31 comprises the circulating fan 312, the detection parameters can comprise, for example, the temperature of the target coil, the air volume of the circulating fan 312, and the transportation speed of the high-temperature transportation unit 32, and the control parameters can comprise, for example, the operating frequency of the circulating fan 312 and the operating frequency of the engine of the high-temperature transportation unit 32. In this case, the control module 1 can, for example, predict the estimated parameters by using the parameter prediction model according to the temperature of the target coil, the air volume of the circulating fan 312, and the transportation speed of the high-temperature transportation unit 32 in the time period from the first historical time to the current time, and determine the control parameters of the temperature control corridor 3 from the current time to the first future time according to the estimated parameters; control the circulating fan 312 to work according to the operating frequency of the circulating fan; and control the high-temperature transportation unit 32 to work according to the operating frequency of the engine of the high-temperature transportation unit 32. Through this implementation manner, if the first heat preservation door 332 and / or the second heat preservation door 333 are in the open state, the control module 1 can control the temperature drop rate of the target coil by adjusting the air volume of the circulating fan 312, for example, increasing the air volume to increase the temperature drop rate of the target coil, and reducing the air volume to reduce the temperature drop rate of the target coil. When the first heat preservation door 332 and the second heat preservation door 333 are in the closed state except when the target coil enters or exits the temperature control corridor 3, the work of the circulating fan 312 can also serve to equalize the temperature in the temperature control corridor 3, that is, to balance the heating of the target coil at different positions, so that the target coil is evenly heated at different positions and the temperature drop rate of the target coil at different positions during transportation is equalized.

[0168] When the temperature control unit 31 comprises both the heating assembly 311 and the circulating fan 312, the two assemblies can be cooperated to better adjust the temperature drop rate of the target coil, improve the operation flexibility, and improve the accuracy of temperature adjustment during transportation of the target coil.

[0169] The wire conveying system with the temperature control corridor 3 in the embodiment includes a control module 1, a conveying module 2, the temperature control corridor 3, and a winding module 4; the temperature control corridor 3 includes a temperature control unit 31, a high-temperature conveying unit 32, a heat preservation unit, and a parameter acquisition unit 34; the heat preservation unit is used for heat preservation of the coil transported by the high-temperature conveying unit 32, and includes a heat preservation wall 331, a first heat preservation door 332, and a second heat preservation door 333; the space between the heat preservation wall 331, the first heat preservation door 332, and the second heat preservation door 333 is a closed space in the closed state of the first heat preservation door 332 and the second heat preservation door 333. On the basis of the above structure, the control module 1 first acquires a winding instruction, and controls the winding module 4 to wind the target coil according to the winding instruction to obtain a target coil; then, the conveying module 2 is controlled to convey the target coil into the first heat preservation door 332 and use the high-temperature conveying unit 32 to convey the target coil; then, the parameter acquisition unit 34 is used to acquire and store the detection parameters related to the target coil in real time when the target coil is conveyed in the temperature control corridor 3; then, the target parameters of the target coil when the target coil is conveyed in the temperature control corridor 3 are acquired; then, according to the detection parameters in the time period from the first historical time to the current time, the estimated parameters corresponding to the target parameters in the time period from the current time to the first future time are predicted; then, according to the difference between the target parameters in the time period from the current time to the first future time and the estimated parameters corresponding to the target parameters in the time period from the current time to the first future time, and the control parameters of the temperature control corridor 3 at the current time, the control parameters of the temperature control corridor 3 in the time period from the current time to the second future time are determined; then, according to the control parameters, the high-temperature conveying unit 32 and the temperature control unit 31 are controlled to work in the time period from the current time to the second future time, until the target coil is conveyed out of the second heat preservation door 333 by the high-temperature conveying unit 32, and the target coil with stable mechanical performance parameters is obtained.

[0170] Since the wire conveying system provided by the application includes the temperature control corridor 3, the influence of the external environment on the wire conveying process can be better insulated when the wire is conveyed in the temperature control corridor 3, the temperature control of the wire in the wire conveying process is more concentrated, the precise and concentrated regulation and control of the wire conveying temperature and speed are realized, the control difficulty is reduced, and the control precision of the conveying process is improved.

[0171] In addition, the transportation system provided in the present application obtains the estimated parameter corresponding to the target parameter in the wire transportation process in a predictive manner, and then adjusts the future control parameter based on the difference between the estimated parameter and the target parameter. Through this implementation manner, the control logic is upgraded to the "front-feedback" PID control, compared with the feedback regulation manner according to the current actual parameter value in the prior art, the action can be taken in advance, the control reaction time is shortened, the system control lag is reduced, and the actual cooling curve can be accurately fitted to the ideal process curve. Further, the overall control accuracy of the system during the transportation process can be better improved, the target coil quality is improved, and unnecessary transportation energy consumption caused by the reaction lag is reduced.

[0172] In addition, in the present application, after the spinning and coiling are completed, the metal microstructure is transformed in the required direction during the transportation process, and the harmful components such as H elements and other harmful components mixed in the metal structure during the rolling process are precipitated, so that the mechanical properties of the metal are improved. Moreover, the process directly utilizes the rolling heat to complete the finishing of the target coil, which avoids the secondary heating process, effectively saves the energy consumption required for the secondary heating of the metal, reduces the energy consumption and time consumption of the intermediate transportation, realizes energy saving, and improves the processing efficiency.

[0173] The control module 1 adjusts the control parameter of the temperature control corridor 3 at the current time according to the above difference, and the adjusted control parameter is taken as the control parameter of the temperature control corridor 3 in the time period from the current time to the second future time. Figure 5 The flowchart of the second wire transportation method with a temperature control corridor provided in the present application is shown in FIG. 6, which comprises the following steps. Figure 5 The step S107 in the above embodiment may, for example, comprise the following steps.

[0174] S201, obtaining the initial control parameter according to the difference between the target parameter in the time period from the current time to the first future time and the estimated parameter corresponding to the target parameter in the time period from the current time to the first future time, and the control parameter of the temperature control corridor at the current time.

[0175] In this step, the control module 1 obtains the initial control parameter according to the difference and the control parameter of the temperature control corridor 3 at the current time, which is taken as the basis for obtaining the control parameter of the temperature control corridor 3 subsequently.

[0176] For example, the control module 1 can adjust the control parameter at the current moment based on the above difference value, the control parameter of the temperature-controlled corridor 3 at the current moment, in a PID tuning manner, or based on an optimization algorithm of a loss function, or a method of reinforcement learning based on a large model, and the present application does not limit it. The specific implementation manner can refer to the prior art, which will not be repeated here.

[0177] S202, obtaining a compensation control parameter according to a difference value between an actual value corresponding to a target parameter at a current moment and an estimated parameter corresponding to the target parameter at the current moment, and a control parameter of a temperature-controlled corridor at the current moment.

[0178] In this step, the control module 1 obtains an initial compensation control parameter according to the difference value and the control parameter of the temperature-controlled corridor 3 at the current moment, which serves as a basis for obtaining the control parameter of the temperature-controlled corridor 3 subsequently.

[0179] The specific obtaining manner can refer to the above step S201, which will not be repeated here.

[0180] S203, fusing the initial control parameter and the compensation control parameter to obtain a control parameter in a time period from the current moment to a second future moment.

[0181] The fusion manner of the above initial control parameter and compensation control parameter may, for example, be any one of an arithmetic mean, a weighted mean, a median, and Kalman filtering, and the present application does not limit it. The specific implementation manner can refer to the prior art, which will not be repeated here.

[0182] It should be noted that the above difference value and the control parameter of the temperature-controlled corridor may include one or more, and the obtaining manner of the control parameter in different situations in the present implementation manner needs to be adjusted accordingly.

[0183] For example, if the difference value and the control parameter each include only one, the control module 1 may, for example, obtain the control parameter of the temperature-controlled corridor in a time period from the current moment to a first future moment by using the following formulas (1)-(3).

[0184] Formula (1):

The above and For example, the above parameters can be determined by field debugging and "controller tuning".

[0188] Alternatively, the control module 1 can obtain the control parameter of the temperature control corridor in the time period from the current time to the first future time by using the following formulas (4) and (5).

Wherein , , and For example, the above parameters can be determined by field debugging and "controller tuning".

[0192] If the difference value and the control parameter each include multiple items, the control module 1 can obtain the control parameter of the temperature control corridor in the time period from the current time to the first future time by calculation in the form of matrix and vector. The specific implementation manner can refer to the prior art, and will not be described here.

[0193] In this embodiment, the control module 1 first acquires the initial control parameter according to the target parameter in the time period from the current time to the first future time, the difference between the target parameter and the estimated parameter corresponding to the target parameter in the time period from the current time to the first future time, and the control parameter of the temperature-controlled corridor 3 at the current time. Then, the control module 1 acquires the compensation control parameter according to the deviation between the actual value corresponding to the target parameter at the current time and the estimated parameter corresponding to the target parameter at the current time, and the control parameter of the temperature-controlled corridor 3 at the current time. Then, the control module 1 fuses the initial control parameter and the compensation control parameter to acquire the control parameter in the time period from the current time to the second future time.

[0194] Since the initial control parameter and the compensation control parameter are fused, that is, the data basis for determining the control parameter is increased, the accuracy of the finally determined control parameter can be improved, so that the control precision of the transportation system provided by the present application can be further improved, the target coil quality can be improved, and the transportation energy consumption caused by the transportation process of the target coil can be saved.

[0195] The specific implementation of the temperature control unit 31 will be described in detail below. As described above, the temperature control unit 31 can include a heating assembly 311. In this implementation, the present application does not limit the specific implementation of the heating assembly 311 and the installation position of the heating assembly 311 in the temperature-controlled corridor 3. For example, the heating assembly 311 can be a resistance wire or a natural gas heating assembly; the heating assembly 311 can be installed equidistantly in the temperature-controlled corridor 3 or can be flexibly configured and installed according to requirements.

[0196] In some embodiments, the heating assembly 311 is a natural gas heating assembly. In this case, the present application does not limit the specific implementation of the natural gas heating assembly and the position of the natural gas heating assembly in the temperature-controlled corridor 3. For example, the natural gas heating assembly can be provided with a gas injection hole in the temperature-controlled corridor 3, and a ignition device is arranged to facilitate the gas injection heating of the target coil.

[0197] Continuing to refer to Figure 4Optionally, the temperature control corridor 3 can further comprise a heat isolation unit 35, which can be located between the heating assembly 311 and the target coil when the high-temperature transportation unit 32 is transporting the target coil, so as to avoid direct heating of the target coil by the heating assembly 311. In this implementation, the application does not limit the specific material and structure of the heat isolation unit, and the connection mode with other components in the temperature control corridor 3. For example, when the heating assembly 311 is a natural gas heating assembly, the heat isolation unit can be connected with the heat preservation wall 331 and located between the gas injection port of the natural gas heating assembly and the target coil, and has a semicircular arc structure. Through this implementation, it can be avoided that the target coil is unevenly heated due to the close distance or direct heating of the heating assembly 311 to the target coil, so as to cause different temperature drop rates of different parts of the target coil and affect the quality of the target coil.

[0198] Figure 6 A schematic diagram of a transverse structure of a temperature control zone provided by the application is shown in the figure. The schematic diagram of the transverse structure of the temperature control zone 5 means the cross-sectional structure schematic diagram of the temperature control zone 5 after cutting along the direction perpendicular to the transportation direction of the target coil. As shown in the figure, Figure 2 and Figure 6 Optionally, in some embodiments, the transportation system provided by the application can further comprise a temperature control zone 5, which comprises a third heat preservation door 51, a temperature detection unit 52, and a cooling unit 53. The space between the first heat preservation door 332, the third heat preservation door 51, the cooling unit 53, and the temperature detection unit 52 is a closed space in the closed state of the cooling unit 53. It should be understood that, Figure 6 the transverse position shown in the figure is the position comprising the temperature detection unit 52 and the cooling unit 53, which does not mean that every position of the temperature control zone 5 comprises the temperature detection unit 52 and the cooling unit 53.

[0199] The application does not limit the specific implementation of the third heat preservation door 51 and the connection mode of the third heat preservation door 51 and other components in the temperature control zone 5, which can be set as needed by those skilled in the art. The implementation of the third heat preservation door 51 can be the same as or different from that of the first heat preservation door 332 and the second heat preservation door 333. For example, the third heat preservation door 51 can be an arch-shaped door or a rectangular door, a flat door or a roller shutter door, a single door or a double door. The specific implementation can refer to the prior art, which will not be described here. It should be understood that the above is only an example, and the application does not limit other possible implementations of the third heat preservation door 51.

[0200] The temperature detection unit 52 is a component for detecting the temperature of the target coil. The application does not limit the specific implementation of the temperature detection unit 52 and the connection mode of other components in the temperature adjustment area 5. For example, the temperature detection unit 52 can include a temperature sensor, such as an infrared temperature detector. In this implementation, the application does not limit the number of temperature sensors included in the temperature detection unit 52, and the installation position in the temperature adjustment area 5 can be configured according to the needs of those skilled in the art.

[0201] The cooling unit 53 is used to cool the target coil. The cooling unit 53 can be a air-cooled component or a water-cooled component. The application does not limit the specific implementation of the air-cooled component and the water-cooled component, and the specific implementation can refer to the prior art, which will not be described here.

[0202] In this implementation, the control module 1 can control the transportation module 2 to transport the target coil into the third temperature adjustment door 51 before transporting the target coil into the first temperature adjustment door 332; then, the control module 1 controls the cooling unit 53 to cool the target coil until the temperature detection unit 52 detects that the temperature of the target coil reaches the target temperature.

[0203] The application does not limit the specific value of the target temperature, which can be set according to the needs of those skilled in the art. The target temperature of different types of target coils can be the same or different. The control module 1 can obtain the target temperature corresponding to the target coil input by the user, or the control module 1 pre-stores a mapping relationship between the target coil type and the target temperature, and the control module 1 obtains the target coil type, and determines the target temperature of the target coil according to the target coil type and the mapping relationship.

[0204] By this way of transporting the target coil into the temperature adjustment area 5 to preliminarily adjust the temperature of the target coil to the target temperature before transporting the target coil into the temperature control corridor 3, the initial temperature of the target coil transported into the temperature control corridor 3 can be preliminarily unified, and the temperature control difficulty of the target coil after entering the temperature control corridor 3 can be reduced. When multiple target coils enter the temperature control corridor 3 at the same time, the initial temperature of the target coils entering the temperature control corridor 3 can be ensured to be the same by this way, and the unified adjustment of the temperature control cooling process can be better realized, the quality of the target coil is improved, the energy efficiency is improved, and the energy consumption is reduced.

[0205] Another embodiment is provided below. Taking the high-speed wire type 82B as an example, the target coil is formed by the wire drawing machine after the steel wire is rolled, and the temperature is about 900°C at this time. After the temperature of the target coil is reduced to about 700°C, the target coil is collected and integrated into a target coil. After the transportation of the transportation module 2 (including an intermediate roller bed and an elevator), the target coil is transported into the temperature control corridor 3. After the target coil is transported into the third temperature holding door 51 by the transportation module 2, the temperature of the target coil is measured at multiple positions by the temperature detection unit 52 (for example, multiple infrared temperature measurement probes), and the signal is transmitted to the control module 1. The control module 1 adjusts the temperature of the target coil according to the measured temperature value to ensure that the temperature of the target coil entering the first temperature holding door 332 is 650°C. After entering the first temperature holding door 332, the control module 1 uses the PID control method of “front feedback” to continuously update the control parameters of the future temperature control corridor 3 based on the wire transportation method provided in the above embodiment, and controls the high-temperature transportation unit 32 and the temperature control unit 31 in the temperature control corridor 3 to keep the target coil at a relatively constant cooling rate during transportation in the temperature control corridor 3, and to be transported for more than 30 minutes in the range of 650-600°C, to ensure that the sorbitol conversion rate is more than 90%. Finally, the target coil is transported out of the second temperature holding door 333 by the high-temperature transportation unit 32, and the target coil with stable mechanical properties is obtained.
