[0043] Thirdly, this application provides a control device applied to a control module as described in the first and second aspects, the control device comprising:

[0044] The first acquisition module is used to acquire volume assembly instructions;

[0045] A control winding module is used to control the winding module to wind up the target coil according to the winding command, so as to obtain the target coil;

[0049] The prediction module is used to predict the estimated parameters corresponding to the target parameters in the time period from the current time to the first future time, based on the detection parameters in the time period from the first historical time to the current time.

[0050] The determining module is used to determine the control parameters of the temperature-controlled corridor in the time period from the current time to the second future time based on 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 parameters of the temperature-controlled corridor in the current time.

[0052] Fourthly, this application provides an electronic device, including: a processor, and a memory and a communication interface communicatively connected to the processor;

[0053] The memory stores computer-executed instructions;

[0054] The processor executes computer execution instructions stored in the memory to implement the method as described in the second aspect.

[0055] Fifthly, this application provides a computer-readable storage medium storing computer-executable instructions that, when executed by a processor, are used to implement the method described in the second aspect.

[0056] In a sixth aspect, this application provides a computer program product, including a computer program that, when executed by a processor, implements the method described in the second aspect.

[0057] The wire rod transport system and method with temperature-controlled corridor provided in this application include a control module, a transport module, a temperature-controlled corridor, and a coil assembly module. The temperature-controlled corridor includes a temperature control unit, a high-temperature transport unit, a heat preservation unit, and a parameter acquisition unit. The heat preservation unit is used to preserve the coils transported by the high-temperature transport unit. The heat preservation unit includes a heat preservation wall, a first heat preservation door, and a second heat preservation door. The space between the heat preservation wall, the first heat preservation door, and the second heat preservation door is a closed space when the first heat preservation door and the second heat preservation door are closed. Based on the above structure, the control module first controls the winding module to wind the target coil according to the winding command to obtain the target coil; then, it controls the transportation module to transport the target coil into the first insulation door and uses the high-temperature transportation unit to transport the target coil; then, it uses the parameter acquisition unit to acquire and store the detection parameters related to the target coil during transportation in the temperature-controlled corridor in real time; then, it acquires the target parameters of the target coil during transportation in the temperature-controlled corridor; then, based on the detection parameters during the time period from the first historical moment to the current moment, it predicts the target parameters during the time period from the current moment to the first future moment. The corresponding estimated parameters are then determined. Then, based on the difference between the target parameter and the estimated parameter corresponding to the target parameter during the time interval from the current time to the first future time, and the control parameters of the temperature-controlled corridor at the current time, the control parameters of the temperature-controlled corridor during the time interval from the current time to the second future time are determined. Then, based on the control parameters, the high-temperature transport unit is controlled during the time interval from the current time to the second future time, and the temperature control unit operates until the high-temperature transport unit transports the target coil out of the second insulated door, obtaining the target coil after its mechanical performance parameters have stabilized.

[0058] Since the wire transport system provided in this application includes a temperature-controlled corridor, it can better isolate the influence of the external environment on the wire transport process when transporting wires in the temperature-controlled corridor, and more centrally realize the temperature control of wires during the wire transport process. This enables precise and centralized regulation of wire transport temperature and speed, reduces control difficulty, and improves the control accuracy of the transport process.

[0059] Furthermore, the transportation system provided in this application allows the control module to obtain estimated parameters corresponding to the target parameters during wire transportation through prediction. Then, based on the difference between the estimated and target parameters, the control parameters are adjusted accordingly. This implementation upgrades the control logic to an advanced "pre-feedback" PID control. Compared to existing technologies that rely on feedback control based on current parameter values, this approach allows for proactive action, shortens control response time, and improves system lag, enabling the actual cooling curve to closely match the ideal process curve. Furthermore, it enhances the overall control accuracy of the system during transportation, improving the quality of the target coil while reducing unnecessary transportation energy consumption caused by system lag.

[0080] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0081] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0082] The following is an explanation of some of the terms used in this application:

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

[0084] Wire spinning: Wire spinning refers to the process of coiling high-speed wire rods into coils after they have come out of the finishing mill using a wire spinning machine.

[0085] Coiling: Coiling refers to the process of collecting the coils of wire or rod that have been coiled by the spinning machine and arranging them into shapes and states that are easy to transport and process later.

[0086] Coil: In the field of high-speed wire rod processing, "coil" refers to the process and finished product state of processing steel into a disc or coil shape using specific equipment.

[0087] Coil: refers to a finished or semi-finished product made of steel rolled into a spiral shape. It is the basic form for subsequent processing. Coil is more loosely structured than coil.

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

[0089] Regarding the control of operating speed, if the roller conveyor runs too fast, it may cause uneven changes in coil temperature or premature termination of the temperature control process, affecting coil quality; if the roller conveyor runs too slowly in order to ensure uniform changes in coil temperature, it may lead to a waste of transport capacity and affect the overall production rhythm.

[0090] Temperature control requirements are even more stringent, and different types of coils often require different temperature control strategies. For example, to form wires with good plasticity and toughness, slow cooling is needed to allow sufficient time for the atoms inside the steel to diffuse and rearrange, forming coarse grain structures such as pearlite and ferrite. To form wires with high strength, hardness, and wear resistance, rapid cooling is needed to prevent atoms from fully diffusing, forming fine and dispersed structures such as martensite and bainite.

[0091] Although the current production line is equipped with a basic temperature-controlled transport system, enabling preliminary temperature control during coil transport, the accuracy of transport speed adjustment is insufficient, and the response speed of the temperature control system is slow, resulting in significant temperature fluctuations of the coils during transport. These problems not only lead to unstable final product quality and significant differences in performance parameters, but also result in low transport efficiency, causing valuable transport resources to be underutilized and impacting the overall economic benefits of the production line.

[0092] The inventors discovered that most existing transport systems use preset control parameters for different types of wire. For example, for a specific type of wire, corresponding transport speed and temperature control parameters (such as the operating frequency of the cooling fan) can be preset. When actually transporting this type of wire, the transport system can be configured with the corresponding control parameters for temperature-controlled transport. However, these parameters are calibrated based on historical experience. In actual transport, due to factors such as coil batches, the stability of the transport system itself, and the external environment, controlling according to preset parameters can lead to differences between the actual temperature-controlled transport process and the ideal process. For example, due to the influence of the external environment, the actual temperature drop rate of the coil during transport may differ significantly from the expected temperature drop rate, resulting in differences in the performance of the final coil.

[0093] Some transportation systems adjust parameters based on feedback from the actual transportation process to ensure that the transport speed and temperature variations of the coils meet the requirements as much as possible. However, this method also has drawbacks. Most of these systems adjust parameters based on current monitoring data, and the adjustment process and the system's response are delayed, affecting the effectiveness of temperature-controlled transport of the coils.

[0094] The inventors considered that if the detection parameters during the coil transportation process could be accurately predicted, and the transportation speed and temperature control parameters could be adjusted based on the predicted detection parameters, the problem of lag in the transportation system's response during parameter adjustment could be overcome, improving the control accuracy of the coil transportation process and enhancing the performance of the acquired coils. In view of this, this application provides a wire transportation system with a temperature-controlled corridor, where the temperature-controlled corridor provides a closed environment for the transportation process, facilitating better isolation from the external environment for temperature-controlled transportation. Furthermore, this transportation system predicts multiple future parameters based on historical detection parameters (such as coil temperature and transportation speed), and adjusts the control parameters of the temperature-controlled corridor during coil transportation based on the predicted parameters. This implementation method enables predictive adjustment of the temperature-controlled corridor's control parameters, achieving front-feedback PID control, improving the problem of lag in the transportation system's response, thereby enhancing the control accuracy of the transportation system during coil transportation, meeting transportation needs while reducing transportation energy consumption and improving coil quality.

[0095] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below through specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

This application does not limit whether the transportation system may include other modules, and those skilled in the art can set them according to their needs.

[0101] The temperature-controlled corridor 3 includes a temperature control unit 31, a high-temperature transport unit 32, a heat preservation unit 33, and a parameter acquisition unit 34. The heat preservation unit 33 is used to preserve the target coil transported by the high-temperature transport unit 32. The heat preservation unit 33 includes an insulation wall 331, a first insulation door 332, and a second insulation door 333. The space between the insulation wall 331, the first insulation door 332, and the second insulation door 333 is a closed space when the first insulation door 332 and the second insulation door 333 are closed.

For example, it can be transported via a roller bed, roller conveyor, etc. The specific implementation of the high-temperature transport unit 32 can refer to the prior art, and will not be elaborated here.

[0103] This application does not limit the specific shape and material of the above-mentioned insulation wall 331. For example, it can be a semi-cylindrical, cuboid, or other shape; the material can be aluminum silicate fiber products as the main insulation material.

[0104] This application does not limit the specific implementation of the first insulated door 332 and the second insulated door 333, nor the connection method with the insulated wall 331. The implementation of the first insulated door 332 and the second insulated door 333 can be the same or different.

Specific implementation methods can refer to the prior art, and will not be elaborated here. It should be understood that the above are only examples and do not limit the possible implementation methods of the first insulated door 332 and the second insulated door 333.

[0105] The specific implementation of the parameter acquisition unit 34 is related to the detection parameters that need to be acquired subsequently. For example, if the detection parameters include the temperature of the target coil, the parameter acquisition unit 34 may include a temperature sensor; if the detection parameters include the airflow / pressure near the target coil, the parameter acquisition unit 34 may include an airflow / pressure sensor; if the detection parameters include the transport speed of the target coil, the parameter acquisition unit 34 may include a transport speed detector; if the detection parameters include the weight of the target coil, the parameter acquisition unit 34 may include a weight sensor.

And so on. Specifically, those skilled in the art can configure it according to their needs.

[0107] It should be understood that the types of sensors and detectors included in the parameter acquisition unit 34 in the above examples are merely examples, and this application does not limit whether the parameter acquisition unit 34 includes other types of sensors or detectors besides those in the above examples.

[0108] This application does not limit the installation location of the parameter acquisition unit 34 in the temperature control corridor 3, and those skilled in the art can set it as needed.

It should be understood that the above examples are merely illustrative, and this application does not limit whether the temperature control unit 31 includes other types of components besides those described above.

[0110] Based on the above structure, this application provides a method for transporting wire rods with a temperature-controlled corridor, which is applied to the control module 1 of the wire rod transport system with a temperature-controlled corridor. Figure 3 A flowchart illustrating the first wire transportation method with a temperature-controlled corridor provided in this application is shown below. Figure 3 As shown, the method may include the following steps:

[0111] S101, Obtain Volume Assembly Command.

[0112] In this step, control module 1 obtains a winding instruction, and controls winding module 4 to wind up the target coil accordingly.

[0113] Optionally, the control module 1 may include a user interface and obtain the roll-up command input by the user through the interface; or, the control module 1 may obtain the roll-up command sent by other devices; or, the wire transport system with temperature-controlled corridor 3 includes a target coil detection component, and the control module 1 uses the target coil detection component to detect whether the coil has been transported to a preset position by the transport module 2.

[0114] The aforementioned other devices may be user terminals, such as mobile phones, tablets, computers, remote controls, etc. The aforementioned target coil detection component may be, for example, an infrared detection component, which may be located at the aforementioned preset position. The control module 1 can determine whether the coil has been transported to the preset position through the infrared detection component. The aforementioned preset position may be, for example, a specific position located in front of the winding module 4, which can be set by those skilled in the art according to requirements.

[0115] Control module 1 can determine whether the winding module 4 can proceed with the winding process of the next coil by using the detection signal fed back from the winding module 4. For example, the winding module 4 may include an infrared detection component, which detects whether the winding module 4 has a coil being wound. If not, it sends a detection signal to control module 1 indicating that the winding process of the next coil can proceed.

[0116] S102. Control the winding module to wind the target coil according to the winding command to obtain the 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, so as to obtain the target coil, which can be used for subsequent processing based on the coil state of the wire, and facilitates operation, transportation and storage.

[0118] This application does not limit the method by which the control module 1 controls the winding module 4 to wind the target coil; the specific method depends on the implementation of the winding module 4. Those skilled in the art can configure it according to their needs. For example, the winding module 4 may include a winding drum, and the control module 1 controls the winding drum in the winding module 4 to wind the coil. Specific implementation methods can be found in existing technologies and will not be elaborated here.

[0119] S103, The control and transportation module transports the target coil into the first insulation door 332 and then uses a high-temperature transportation unit to transport the target coil.

[0120] In this step, control module 1 controls transport module 2 to transport the target coil into the first insulation door 332 and switch to high-temperature transport unit 32 to transport the target coil, so as to enable centralized and precise temperature-controlled transport of the target coil.

[0121] Optionally, before the transport module 2 transports the target coil into the first insulated door 332, the first insulated door 332 may be in a closed state. When the control module 1 controls the transport module 2 to transport the target coil into the first insulated door 332, the first insulated door 332 opens to facilitate the entry of the target coil. After the transport module 2 transports the target coil into the first insulated door 332, the first insulated door 332 closes. This implementation method can minimize the isolation of the target coil from the external environment during temperature-controlled transport, reduce the control difficulty of the wire transport process, further improve the parameter control accuracy during transport, and enhance the temperature-controlled transport effect.

[0122] S104. The parameter acquisition unit 34 is used to acquire and store the detection parameters related to the target coil during transportation in the temperature-controlled corridor in real time.

[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 real time during the transportation of the target coil in the temperature-controlled corridor 3, so as to predict the future detection parameters, temperature drop rate and other transportation status of the target coil.

[0124] The aforementioned detection parameters related to the target coil may include one or more of the following: the temperature of the target coil, the wind pressure / air volume near the target coil, the transport speed of the target coil, the humidity near the target coil, and the weight of the target coil.

[0125] The parameter acquisition unit 34 can acquire the above-mentioned detection parameters periodically, or it can acquire the above-mentioned detection parameters at regular intervals, or it can adopt a parameter acquisition method that combines periodic acquisition and regular acquisition.

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

[0127] The acquisition frequency of different detection parameters can be the same or different, depending on the specific detection parameter 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 transport speed every 2 minutes.

[0128] S105. Obtain the target parameters when the target coil is transported in the temperature-controlled corridor.

[0129] The aforementioned target parameters refer to the ideal performance parameters of the target coil during transportation in the temperature-controlled corridor 3. For example, these may include one or more of the following: target temperature drop rate of the target coil, target transportation time, target transportation speed, target temperature, and the variance / standard deviation of the temperature within the same coil. The above are merely examples, and this application does not limit whether the target parameters may include other items.

[0130] The specific values ​​of the target parameters may be determined offline by staff, based on experience, or by consulting literature; this application does not limit them.

[0131] The target temperature drop rate mentioned here refers to the ideal temperature drop rate. The target transport time is the ideal transport time of the target coil in the temperature-controlled corridor 3. The target transport rate is the ideal transport rate of the target coil in the temperature-controlled corridor 3. The target temperature is the ideal temperature of the target coil when it is transported to different positions in the temperature-controlled corridor 3. The variance / standard deviation of the temperature of the same coil of the target coil is the variance / standard deviation of the temperature at different positions of the same coil of the target coil. The above-mentioned different target parameters can be individual values ​​or ranges; this application does not limit them.

[0132] One possible implementation is that the control module 1 can obtain the target parameters input by the user. For example, the control module 1 may include a user interface to obtain the target parameters input by the user.

[0133] Another possible implementation is that the control module 1 can first obtain the type of the target disk; then, based on the type of the target disk, determine the target parameters of the target disk.

[0134] Control module 1 can directly obtain the type of the target disk volume input by the user, or it can obtain the type of the target disk volume input by other devices, such as computers, mobile phones, tablets, and remote controls. Control module 1 can, for example, store a mapping relationship between target disk volume types and target parameters. After obtaining the type of the target disk volume, control module 1 determines the target parameters of the target disk volume based on the target disk volume type and the aforementioned mapping relationship. This implementation method eliminates the need for the user to manually input target parameters; instead, it simplifies the operation, improves ease of use, and enhances the user experience by simply obtaining the target disk volume type.

[0135] It should be noted that this step can be performed before steps S101-S104, or simultaneously with any of steps S101-S104, or after steps S101-S104. This application does not limit it.

[0136] S106. Based on the detection parameters during the time period from the first historical moment to the current moment, predict the estimated parameters corresponding to the target parameters during the time period from the current moment to the first future moment.

[0137] The time period between the first historical moment and the current moment is the historical time period. Based on this, this application does not limit which specific moment the first historical moment refers to; those skilled in the art can set it as needed. It should be understood that the time period between the first historical moment and the current moment includes the current moment.

[0138] The time period from the current moment to the first future moment is the future time period. Based on this, this application does not limit which specific future moment the first future moment refers to; those skilled in the art can set it as needed. It should be understood that the time period from the current moment to the first future moment does not include the current moment.

[0139] The estimated parameters mentioned here correspond to the target parameters; that is, the target parameters include the same parameter items as the estimated parameters. For example, if the target parameters include the target temperature drop rate of the target coil, the target transportation time, and the variance / standard deviation of the temperature within the same coil of the target coil, then the estimated parameters will also include the target temperature drop rate of the target coil, the target transportation time, and the variance / standard deviation of the temperature within the same coil of the target coil. And so on.

[0140] Optionally, control module 1 can first predict the detection parameters related to the target reel from the current time to the first future time based on the detection parameters from the first historical time to the current time. Then, it determines the estimated parameters based on the detection parameters related to the target reel from the current time to the first future time.

[0141] Alternatively, control module 1 can directly predict and estimate parameters based on the detection parameters during the time period from the first historical moment to the current moment, without first predicting the detection parameters related to the target reel during the time period from the current moment to the first future moment.

[0142] Optionally, control module 1 can determine the estimated parameters based on the detection parameters during the time period from the first historical moment to the current moment, and the mapping relationship between the detection parameters and the estimated parameters. For example, control module 1 can store the mapping relationship between the detection parameters and the estimated parameters, and after obtaining the detection parameters during the time period from the first historical moment to the current moment, control module 1 determines the estimated parameters based on the above mapping relationship.

[0143] Optionally, the control module 1 can use a parameter prediction model to predict the estimated parameters corresponding to the target parameters during the time period from the current time to the first future time, based on the detection parameters during the time period from the first historical time to the current time.

[0144] For example, control module 1 can use the detection parameters within the time period from the first historical moment to the current moment as input to the parameter prediction model, and use the parameter prediction model to output the estimated parameters corresponding to the target parameters within the time period from the current moment to the first future moment.

[0145] Alternatively, control module 1 can use the detection parameters from the first historical moment to the current moment as input to the parameter prediction model, and use the parameter prediction model to output the predicted detection parameters of the target reel for the period from the current moment to the first future moment. Then, based on the predicted detection parameters of the target reel for the period from the first historical moment to the current moment, the estimated parameters corresponding to the target parameters for the period from the current moment to the first future moment are calculated. It should be noted that in this implementation, there is a correspondence between the detection parameters of the target reel and the estimated parameters for the period from the current moment to the first future moment. Control module 1 can calculate and obtain the estimated parameters based on the detection parameters of the target reel for the period from the current moment to the first future moment.

[0146] For example, the detection parameters of the target coil during the time period from the current moment to the first future moment may include the estimated temperature of the target coil during that time period. The estimated parameters may include, for example, the estimated temperature drop rate of the target coil. Control module 1 can calculate the estimated temperature drop rate of the target coil during that time period based on its temperature. The specific calculation method can refer to existing technologies and will not be elaborated here. And so on.

[0147] The aforementioned parameter prediction model can be obtained by training any machine learning model with parameter prediction capabilities. The machine learning model mentioned here can be, for example, a neural network model, a Bayesian model, etc., which can be selected by those skilled in the art according to their needs. It should be understood that the model prototype mentioned here is only an example; in specific implementations, any model with parameter prediction capabilities can be used as a prototype for training or debugging to obtain the parameter prediction model.

[0148] It should be understood that the training methods of the parameter prediction models used in the different implementation methods described above are different. For example, if control module 1 uses the detection parameters within the time period from the first historical moment to the current moment as the input of the parameter prediction model, and uses the parameter prediction model to output the estimated parameters corresponding to the target parameters within the time period from the current moment to the first future moment, then the training method of the parameter prediction model can be, for example, using the detection parameters of other rolls within the time period from the second historical moment to the reference moment as input, and using the parameters corresponding to each item of the target parameter within the time period from the historically acquired reference moment to the third future moment as labels, and training any machine learning model to obtain the results. The relative time relationship between the second historical moment and the current moment is the same as the relative time relationship between the first historical moment and the current moment; the relative time relationship between the third future moment and the current moment is the same as the relative time relationship between the first future moment and the current moment. The types of the other rolls mentioned above can be the same as the target roll type. Based on this, the specific training method of the parameter prediction model can refer to the existing technology, and will not be elaborated here.

[0149] If control module 1 uses the detection parameters from the time interval between the first historical moment and the current moment as input to the parameter prediction model, and uses the parameter prediction model to output the predicted detection parameters of the target disk from the time interval after the current moment to the first future moment, then the parameter prediction model can be trained, for example, by using the detection parameters of other disks from the time interval between the second historical moment and the current moment as input, and using the detection parameters from the time interval after the current moment to the third future moment as labels, to train any machine learning model. Based on this, specific implementation methods can refer to existing technologies, which will not be elaborated here.

[0150] The detection parameters obtained in the above-mentioned historical period, the estimated parameters corresponding to the detection parameters in the time period between the second historical moment and the reference moment, or the detection parameters in the time period between the reference moment and the third future moment can be manually configured, or they can be obtained by collecting parameters based on the historical process of winding and transporting the target disk. This application does not limit them.

[0151] Optionally, in some embodiments, the control model can be based on a pre-built digital twin model to predict the estimated parameters corresponding to the target parameters in the time period from the current time to the first future time, based on the detection parameters in the time period between the first historical time and the current time. This application does not limit the way the digital twin model is built; specific implementation methods can refer to existing technologies, which will not be elaborated here.

[0152] Optionally, in some embodiments, the control module 1 may use a parameter prediction model to predict the estimated parameters corresponding to the target parameters in the time period from the current time to the first future time, based solely on the detection parameters within the time period from the first historical time to the current time. In some embodiments, the control module 1 may use a parameter prediction model to predict the estimated parameters corresponding to the target parameters in the time period from the current time to the first future time, based on the detection parameters within the time period from the first historical time to the current time, and other data. The other data mentioned here may include, for example, the control parameters within the time period from the first historical time to the current time. This implementation method can increase the data foundation for predicting the estimated parameters, thereby improving the prediction accuracy of the estimated parameters, further improving the accuracy of the finally obtained control parameters, and improving the control accuracy of the control system provided in this application. It should be understood that under this implementation method, the training method of the parameter prediction model needs to be adaptively adjusted according to requirements. For example, if prediction is based on the aforementioned other data, then the parameter prediction model training process needs to use the other data as one of the input data to train the model.

[0153] S107. Based on the difference between the target parameter and the estimated parameter corresponding to the target parameter during the time period from the current time to the first future time, and the control parameter of the temperature-controlled corridor at the current time, determine the control parameter of the temperature-controlled corridor during the time period from the current time to the second future time.

[0154] The second future moment may refer to the same future moment as the first future moment, or it may refer to a different future moment than the first future moment. This application does not limit it.

[0155] The difference referred to here is the difference between the corresponding parameter items of the target parameter and the estimated parameter. This difference can be one or more. For example, if the target parameters include the target temperature drop rate, the target transport rate, and the target holding time, and the estimated parameters include the estimated temperature drop rate, the estimated transport rate, and the estimated holding time, then the difference could include, for example, the difference between the target temperature drop rate and the estimated temperature drop rate, the difference between the target transport rate and the estimated transport rate, and the difference between the target holding time and the estimated holding time.

[0156] The control parameters mentioned here are those used to control the various modules and components within the transportation system provided in this application. The specific parameter items included in the control parameters are related to the specific implementation of the high-temperature transportation unit 32 and the temperature control unit 31. For example, if the high-temperature transportation unit 32 includes an engine for driving the high-temperature transportation unit 32, the control parameters may include, for example, the operating frequency of the engine; if the temperature control unit 31 includes a heating component, the control parameters may include, for example, the thermal power of the heating component; if the temperature control unit 31 includes an air-cooled component, the control parameters may include, for example, the operating frequency of the fan; if the temperature control unit 31 includes a water-cooled component, the control parameters may include, for example, the operating frequency of the engine of the water-cooled component.

[0157] Optionally, in one possible implementation, control module 1 stores the difference, the control parameters of the temperature-controlled corridor 3 at the current moment, and the mapping relationship between the control parameters during the time period from the current moment to the second future moment. Control module 1 determines the control parameters during the time period from the current moment to the second future moment based on the difference, the control parameters of the temperature-controlled corridor 3 at the current moment, and the aforementioned mapping relationship. This application does not limit the mapping method; for example, it can use an interval mapping method, as detailed in existing technologies, which will not be elaborated here.

[0158] Alternatively, another possible implementation is to use the control parameter at the current moment as the control parameter for the time period between the current moment and the second future moment if the difference is within a preset error range.

[0159] This application does not limit the specific range of the aforementioned preset error range; those skilled in the art can set it according to their needs. In this case, since the difference between the two is within the preset error range, it proves that the current transportation process of the target coil is in line with expectations, and the current control parameters meet the transportation requirements. Therefore, the control parameters at the current moment can be directly used as the control parameters for the time period from the current moment to the second future moment.

[0160] If the difference is not within the preset error range, the control parameters at the current time are adjusted according to the difference, and the adjusted control parameters are used as the control parameters for the time period from the current time to the second future time.

[0161] When multiple differences are included, the term "difference not within the preset error range" can refer to any one or more differences not within the preset error range, or all differences not within the preset error range.

[0162] Optionally, in this implementation, control module 1 can adjust the control parameters at the current moment based on the aforementioned difference and the control parameters at the current moment using PID tuning, an optimization algorithm based on a loss function, or a reinforcement learning method based on a large model. Specific implementation methods can refer to existing technologies and will not be elaborated here.

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

[0164] S108. According to the control parameters, control the high-temperature transport unit and the temperature control unit to work during the time period from the current time to the second future time until the high-temperature transport unit transports the target coil out of the second heat preservation door 333 and obtains the target coil after the mechanical performance parameters have stabilized.

[0165] The mechanical performance parameters mentioned here may include, for example, the target coil's high sorbite content, high shrinkage area, low H content, tensile strength, and other parameters.

[0166] For example, Figure 4 This application provides a cross-sectional structural diagram of a temperature-controlled corridor, using a temperature control unit 31 including a heating element 311 and a circulating fan 312 as an example. The cross-sectional structural diagram of the temperature-controlled corridor 3 described here refers to the cross-sectional structure after cutting the temperature-controlled corridor 3 along a direction perpendicular to the target coil transport direction. It should be understood that... Figure 4 The cross-section shown indicates the location including the heating element 311 and the circulating fan 312, but does not mean that every location in the temperature control corridor 3 includes the heating element 311 and the circulating fan 312. Figure 4 As shown, if the temperature control unit 31 includes a heating component 311, the control parameters may include, for example, the heat power of the heating component 311. The control module 1 may control the heating component 311 to perform thermal compensation on the target coil according to the heat power, so as to achieve precise temperature control and cooling of the target coil during transportation.

[0167] If the temperature control unit 31 includes a circulating fan 312, the detection parameters may include, for example, the temperature of the target coil, the airflow of the circulating fan 312, and the transport rate of the high-temperature transport unit 32. The control parameters may include, for example, the operating frequency of the circulating fan 312 and the operating frequency of the engine of the high-temperature transport unit 32. In this case, the control module 1 may, for example, use a parameter prediction model to predict and estimate parameters based on the temperature of the target coil, the airflow of the circulating fan 312, and the transport rate of the high-temperature transport unit 32 during the time period from the first historical moment to the current moment, and thereby determine the control parameters of the temperature-controlled corridor 3 from the current moment to the first future moment; control the operation of the circulating fan 312 based on the operating frequency of the circulating fan; and control the operation of the high-temperature transport unit 32 based on the operating frequency of the engine of the high-temperature transport unit 32. With this implementation, if the first insulation door 332 and / or the second insulation door 333 are in a normally open state, the control module 1 can use the circulating fan 312 to control the temperature drop rate of the target coil by adjusting the air volume. For example, increasing the air volume can increase the temperature drop rate of the target coil; decreasing the air volume can decrease the temperature drop rate of the target coil. When the first insulation door 332 and the second insulation door 333 are both in a closed state except when the target coil enters or exits the temperature control corridor 3, the operation of the circulating fan 312 can also play a role in equalizing the temperature within the temperature control corridor 3, that is, it can evenly distribute the heat to all parts of the target coil, making the target coil heat evenly distributed and maintaining a uniform temperature drop rate throughout the target coil during transportation.

[0168] When the temperature control unit 31 includes both the heating component 311 and the circulating fan 312, the temperature drop rate of the target coil can be better adjusted through the cooperation of the two components, thereby improving operational flexibility and the accuracy of temperature regulation during the transportation of the target coil.

[0169] In this embodiment, the wire transport system with temperature-controlled corridor 3 includes a control module 1, a transport module 2, a temperature-controlled corridor 3, and a coil assembly module 4. The temperature-controlled corridor 3 includes a temperature control unit 31, a high-temperature transport unit 32, a heat preservation unit, and a parameter acquisition unit 34. The heat preservation unit is used to keep the coils transported by the high-temperature transport unit 32 warm. The heat preservation unit 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 when the first heat preservation door 332 and the second heat preservation door 333 are closed. Based on the above structure, control module 1 first obtains a winding command and controls winding module 4 to wind the target coil according to the command, thus obtaining the target coil. Then, control transport module 2 to transport the target coil into the first insulation door 332 and switch to high-temperature transport unit 32 for transporting the target coil. Then, parameter acquisition unit 34 acquires and stores the detection parameters related to the target coil in real time during transport in the temperature-controlled corridor 3. Then, target parameters of the target coil during transport in the temperature-controlled corridor 3 are acquired. Then, based on the detection parameters during the time period from the first historical moment to the current moment, the parameters related to the target coil during the time period from the current moment to the first future moment are predicted. The corresponding estimated parameters are determined; then, based on the difference between the target parameters and the estimated parameters corresponding to the target parameters during the time period from the current time to the first future time, and the control parameters of the temperature-controlled corridor 3 at the current time, the control parameters of the temperature-controlled corridor 3 during the time period from the current time to the second future time are determined; then, based on the control parameters, the high-temperature transport unit 32 and the temperature control unit 31 are controlled to work during the time period from the current time to the second future time until the high-temperature transport unit 32 transports the target coil out of the second insulation door 333, and the target coil with stable mechanical performance parameters is obtained.

[0170] Since the wire transport system provided in this application includes a temperature-controlled corridor 3, it can better isolate the influence of the external environment on the wire transport process when transporting wires in the temperature-controlled corridor 3, and more centrally realize the temperature control of wires during the wire transport process. This enables precise and centralized regulation of wire transport temperature and speed, reduces control difficulty, and improves the control accuracy of the transport process.

[0171] Furthermore, the transportation system provided in this application allows the control module 1 to obtain estimated parameters corresponding to the target parameters during wire transportation through prediction. Then, based on the difference between the estimated parameters and the target parameters, the control parameters are adjusted accordingly. This implementation upgrades the control logic to an advanced "pre-feedback" PID control. Compared to the existing technology's feedback control based on current actual parameter values, this approach allows for earlier action, shortens control response time, reduces system control lag, and enables the actual cooling curve to closely match the ideal process curve. Furthermore, it can better improve the overall control accuracy of the system during transportation, enhance the quality of the target coil, and reduce unnecessary transportation energy consumption caused by system lag.

[0172] Furthermore, in this application, after the wire is rolled and coiled, the metal microstructure undergoes a transformation to the desired direction during transportation, and harmful components such as hydrogen (H) that were incorporated into the metal microstructure during rolling are precipitated, thereby improving the mechanical properties of the metal. Moreover, this process directly utilizes the heat of rolling to finish the target coil, eliminating the need for a secondary heating process. This not only effectively saves the energy consumed by secondary heating of the metal but also reduces the energy and time spent on intermediate handling and transportation, achieving energy conservation while improving processing efficiency.

[0173] The following is an example of how control module 1 adjusts the control parameters of the temperature-controlled corridor 3 at the current moment based on the above difference, and uses the adjusted control parameters as the control parameters of the temperature-controlled corridor 3 for the time period from the current moment to the second future moment. Figure 5 A flowchart illustrating the second wire transportation method with a temperature-controlled corridor provided in this application is shown below. Figure 5 As shown, step S107 in the above embodiment may include, for example, the following steps:

[0174] S201. Based on the difference between the target parameter during the time period from the current time to the first future time and the estimated parameter corresponding to the target parameter during the time period from the current time to the first future time, as well as the control parameter of the temperature-controlled corridor at the current time, obtain the initial control parameters.

[0175] In this step, control module 1 obtains initial control parameters based on the difference and the control parameters of the temperature-controlled corridor 3 at the current moment, which serve as the basis for obtaining the control parameters of the temperature-controlled corridor 3 in the future.

[0176] For example, control module 1 can adjust the control parameters at the current moment based on the above difference and the control parameters of the temperature-controlled corridor 3 at the current moment using PID tuning, or an optimization algorithm based on a loss function, or a reinforcement learning method based on a large model. This application does not limit these methods. Specific implementation methods can refer to existing technologies, which will not be elaborated here.

[0177] S202. Obtain the compensation control parameters based on the actual value of the target parameter at the current time, the difference between the estimated parameter at the current time and the target parameter, and the control parameters of the temperature-controlled corridor at the current time.

[0178] In this step, control module 1 obtains initial compensation control parameters based on the difference and the control parameters of the temperature-controlled corridor 3 at the current moment, which serve as the basis for obtaining the control parameters of the temperature-controlled corridor 3 in the future.

[0179] The specific method for obtaining the information can be found in step S201 above, and will not be repeated here.

[0180] S203. Combine the initial control parameters and the compensation control parameters to obtain the control parameters for the time period from the current time to the second future time.

[0181] The fusion method of the above-mentioned initial control parameters and compensation control parameters can be any one of arithmetic average, weighted average, median, or Kalman filtering. This application does not limit it. The specific implementation method can refer to the existing technology, which will not be elaborated here.

[0182] It should be noted that the above-mentioned difference and the control parameters of the temperature-controlled corridor may include one or more parameters. The method of obtaining the control parameters in different situations in this implementation needs to be adjusted accordingly.

[0183] For example, if the difference and the control parameter each include only one item, the control module 1 can use the following formulas (1)-(3) to obtain the control parameters of the temperature-controlled corridor during the time period from the current time to the first future time.

[0184] Formula (1):

[0185] Formula (2):

[0186] Formula (3):

[0187] in, These are the initial control parameters. These are the control parameters at the current moment. The first weighting coefficient, This is the difference between the target parameter during the time interval from the current time to the first future time and the predicted parameter corresponding to the target parameter during the same time interval. To compensate for control parameters, This is the second weighting coefficient. This is the difference between the actual value of the target parameter at the current moment and the estimated parameter at the current moment that corresponds to the target parameter. These are the control parameters for the temperature-controlled corridor 3 during the time period from the current moment to the first future moment. The above... and For example, it can be determined through on-site commissioning and "controller tuning".

[0188] Alternatively, control module 1 can use the following formulas (4) and (5) to obtain the control parameters of the temperature-controlled corridor during the time period from the current moment to the first future moment.

[0189] Formula (4):

[0190] Formula (5):

[0191] in This refers to the change in the control parameters of the temperature-controlled corridor 3 during the time interval from the current moment to the first future moment. It is the difference between the current time and the previous time. for The previous difference. For proportionality coefficient, For integral coefficients, Differential coefficients, This is the third weighting coefficient. , , and For example, it can be determined through on-site commissioning and "controller tuning".

[0192] If both the difference and the control parameters include multiple items, then control module 1 can, for example, use matrix and vector methods to calculate and obtain the control parameters of the temperature-controlled corridor for the time period from the current moment to the first future moment. Specific implementation methods can refer to existing technologies and will not be elaborated here.

[0193] In this embodiment, control module 1 first obtains initial control parameters based on the difference between the target parameter and the estimated parameter corresponding to the target parameter during the time period from the current time to the first future time, as well as the control parameters of the temperature-controlled corridor 3 at the current time. Then, it obtains compensated control parameters based on the actual value of the target parameter at the current time, the deviation between the estimated parameter and the target parameter at the current time, and the control parameters of the temperature-controlled corridor 3 at the current time. Finally, it merges the initial control parameters and the compensated control parameters to obtain the control parameters for the time period from the current time to the second future time.

[0194] By incorporating initial control parameters and compensation control parameters, the data base for determining control parameters is expanded, thereby improving the accuracy of the final determined control parameters. This allows for further improvement in the control precision of the transportation system provided in this application, enhancing the quality of the target coil and saving transportation energy consumption during the target coil transportation process.

[0195] The specific implementation of the temperature control unit 31 is described in detail below. As mentioned above, the temperature control unit 31 may include a heating component 311. In this implementation, this application does not limit the specific implementation of the heating component 311 or its installation position in the temperature control corridor 3. For example, the heating component 311 may be a resistance wire or a natural gas heating component; the heating component 311 may be installed at equal intervals in the temperature control corridor 3, or it may be flexibly configured and installed according to requirements.

[0196] In some embodiments, the heating component 311 is a natural gas heating component. In this case, this application does not limit the specific implementation of the natural gas heating component or its location in the temperature control corridor 3. For example, the natural gas heating component may have jet holes and an ignition device provided in the temperature control corridor 3 to facilitate jet heating of the target coil.

[0197] Continue to refer to Figure 4Optionally, the temperature-controlled corridor 3 may also include a thermal insulation unit 35. When the high-temperature transport unit 32 transports the target coil, the thermal insulation unit 35 can be located between the heating component 311 and the target coil to prevent the heating component 311 from directly heating the target coil. In this implementation, this application does not limit the specific material, structure, or connection method of the insulation unit to other components in the temperature-controlled corridor 3. For example, when the heating component 311 is a natural gas heating component, the insulation unit can be connected to the insulation wall 331 and located between the natural gas heating component's nozzle and the target coil, presenting a semi-circular arc structure. This implementation avoids uneven heating of the target coil due to the close proximity of the heating component 311 to the target coil or direct heating, which would lead to different temperature drop rates at different points on the target coil and affect its quality.

[0198] Figure 6 This is a schematic diagram of the cross-sectional structure of a temperature-regulating zone provided in this application. The schematic diagram of the cross-sectional structure of the temperature-regulating zone 5 referred to here is a schematic diagram of the cross-sectional structure after cutting the temperature-regulating zone 5 along a direction perpendicular to the target coil transport direction. For example... Figure 2 and Figure 6 As shown, optionally, in some embodiments, the transportation system provided in this application may further include a temperature-regulating zone 5, which includes a third heat-insulating door 51, a temperature detection unit 52, and a cooling unit 53. The space between the first heat-insulating door 332, the third heat-insulating door 51, the cooling unit 53, and the temperature detection unit 52 is a closed space when the cooling unit 53 is closed. It should be understood that... Figure 6 The cross-sectional position shown is the position including the temperature detection unit 52 and the cooling unit 53, and does not mean that every position in the temperature control zone 5 includes the temperature detection unit 52 and the cooling unit 53.

[0199] This application does not limit the specific implementation of the third insulation door 51 or the connection method between the third insulation door 51 and other components of the temperature control zone 5. Those skilled in the art can configure it as needed. The implementation of the third insulation door 51 can be the same as or different from that of the first insulation door 332 and the second insulation door 333. For example, the third insulation door 51 can be an arched door or a rectangular door, a swing door or a roller shutter door, a single door or a double door. Specific implementation methods can refer to the prior art, and will not be elaborated here. It should be understood that the above are only examples, and this application does not limit other possible implementations of the third insulation door 51.

[0200] The temperature detection unit 52 described above is a component used to detect the temperature of the target coil. Based on this, this application does not limit the specific implementation of the temperature detection unit 52, nor its connection method with other components of the temperature control zone 5. For example, the temperature detection unit 52 may include a temperature sensor, such as an infrared temperature detector. In this implementation, this application does not limit the number of temperature sensors included in the temperature detection unit 52, nor its installation location in the temperature control zone 5; those skilled in the art can configure it according to their needs.

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

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

[0203] This application does not limit the specific value of the target temperature; those skilled in the art can set it according to their needs. The target temperatures of different types of target reels can be the same or different. For example, the control module 1 can obtain the target temperature corresponding to the target reel input by the user, or the control module 1 can pre-store the mapping relationship between target reel types and target temperatures. After obtaining the target reel type, the control module 1 determines the target temperature of the target reel based on the target reel type and the above mapping relationship.

[0204] By transporting the target coil to the temperature-regulating zone 5 before it enters the temperature-controlled corridor 3 to initially adjust its temperature to the target temperature, the initial temperature of the target coils transported into the temperature-controlled corridor 3 can be uniformly standardized, thereby reducing the difficulty of temperature control after the target coils enter the corridor 3. When multiple target coils enter the temperature-controlled corridor 3 simultaneously, this method ensures that the initial temperature of the target coils entering the corridor 3 is the same, thus better achieving unified adjustment of the temperature control and cooling process, improving the quality of the target coils while increasing energy efficiency and reducing energy consumption.

[0205] The following is another embodiment provided by this application. Taking high-speed wire rod of type 82B as an example, after the steel of this type is rolled, it is formed into a target coil by a wire drawing machine at a temperature of about 900°C. After the temperature of the target coil drops to about 700°C, it is hot-coiled to form a target coil. The target coil is transported into the temperature-controlled corridor 3 by the transport module 2 (including intermediate roller bed and elevator). After the transport module 2 transports the target coil into the third heat preservation door 51, the temperature detection unit 52 (e.g., multiple infrared temperature probes) measures the temperature of the target coil at multiple points and transmits the signal to the control module 1. The control module 1 controls the cooling module to fine-tune the temperature of the target coil according to the measured temperature value to ensure that the temperature of the target coil entering the first heat preservation door 332 is 650°C. After entering the first insulated door 332, the control module 1, based on the wire transport method with temperature-controlled corridor 3 provided in the above embodiment, continuously updates the control parameters of the temperature-controlled corridor 3 in real time using a "pre-feedback" PID control method. Based on this, it controls the operation of the high-temperature transport unit 32 and the temperature control unit 31 in the temperature-controlled corridor 3, ensuring that the target coil maintains a relatively constant cooling rate during transport in the temperature-controlled corridor 3, and is transported within the range of 650-600℃ for more than 30 minutes to ensure a sorbite conversion rate of over 90%. Finally, the high-temperature transport unit 32 transports the target coil out of the second insulated door 333, resulting in a target coil with stabilized mechanical properties.

[0206] Figure 7 This is a schematic diagram of a control device provided in this application. This control device is applied to the control module in the above embodiments, such as... Figure 7 As shown, the control device includes: a first acquisition module 11, a control roll-up module 12, a control transport module 13, a parameter acquisition module 14, a second acquisition module 15, a prediction module 16, a determination module 17, and a control operation module 18. In some embodiments, the control device may also include a temperature control module 19.

[0207] The first acquisition module 11 is used to acquire volume assembly instructions;

[0208] The control winding module 12 is used to control the winding module 4 to wind up the target coil according to the winding command, so as to obtain the target coil.

[0209] The control transport module 13 is used to control the transport module to transport the target coil into the first heat preservation door and switch to the high temperature transport unit to transport the target coil.

[0210] Parameter acquisition module 14 is used to acquire and store detection parameters related to the target coil in real time when the target coil is transported in the temperature-controlled corridor using the parameter acquisition unit;

[0211] The second acquisition module 15 is used to acquire the target parameters of the target coil during transportation in the temperature-controlled corridor 3;

[0212] Prediction module 16 is used to predict the estimated parameters corresponding to the target parameters in the time period from the current time to the first future time based on the detection parameters in the time period from the first historical time to the current time.

[0213] The determining module 17 is used to determine the control parameters of the temperature-controlled corridor in the time period from the current time to the second future time based on 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 parameters of the temperature-controlled corridor in the current time.

[0214] The control module 18 is used to control the high-temperature transport unit during the time period from the current moment to the second future moment according to the control parameters, and the temperature control unit operates until the high-temperature transport unit transports the target coil out of the second heat preservation door to obtain the target coil after the mechanical performance parameters have stabilized.

[0215] One possible implementation is that the prediction module 16 is specifically used to predict the estimated parameters corresponding to the target parameters in the time period from the current time to the first future time, based on the detection parameters in the time period between the first historical time and the current time, and the control parameters of the temperature-controlled corridor in the time period between the first historical time and the current time, using a parameter prediction model.

[0216] One possible implementation is that the determining module 17 is specifically used to: if the difference is within a preset error range, use the control parameters of the temperature-controlled corridor at the current time as the control parameters of the temperature-controlled corridor for the time period from the current time to the first future time; if the difference is not within the preset error range, adjust the control parameters of the temperature-controlled corridor at the current time according to the difference, and use the adjusted control parameters as the control parameters of the temperature-controlled corridor for the time period from the current time to the second future time.

[0217] For example, the determining module 17 is specifically used to obtain initial control parameters based on the difference and the control parameters of the temperature-controlled corridor at the current time; to obtain compensation control parameters based on the difference between the actual value of the target parameter at the current time and the estimated parameter of the target parameter at the current time, and the control parameters of the temperature-controlled corridor at the current time; and to fuse the initial control parameters and the compensation control parameters to obtain control parameters for the time period from the current time to the second future time.

[0218] In one possible implementation, the system further includes a temperature control zone comprising a third insulation door, a temperature detection unit, and a cooling unit. The space between the first insulation door, the third insulation door, the cooling unit, and the temperature detection unit is a closed space when the first insulation door, the third insulation door, and the cooling unit are all closed. The temperature control module 19 is used to control the transport module to transport the target coil into the third insulation door before controlling the transport module to transport the target coil into the first insulation door; and to control the cooling unit to cool the target coil until the temperature detection unit detects that the temperature of the target coil has reached the target temperature.

[0219] In one possible implementation, the temperature control unit includes a heating component, and the temperature control corridor includes a thermal isolation unit. When the target coil is transported by the high-temperature transport unit, the thermal isolation unit is located between the heating component and the target coil to prevent the heating component from directly heating the target coil.

[0220] One possible implementation is that the second acquisition module 15 is specifically used to acquire the type of the target coil; and based on the type of the target coil, acquire the target parameters of the target coil during transportation in the temperature-controlled corridor.

[0221] In one possible implementation, the temperature control unit further includes a circulating fan, and the control parameters include the thermal power of the heating component, the transport rate of the high-temperature transport unit, and the operating frequency of the circulating fan.

[0222] One possible implementation is that the target parameters include one or more of the following: target temperature drop rate, target heat preservation time, and target transport rate; the detection parameters related to the target coil include one or more of the following: temperature of the target coil, air humidity near the target coil, transport speed of the target coil, and air volume near the target coil.

[0223] The control device provided in this application embodiment can execute the wire transportation method with a temperature-controlled corridor executed by the control module in the above method embodiment. Its implementation principle and technical effects are similar, and will not be repeated here. It should be noted that the above... Figure 7 The division of modules shown is merely illustrative. This application does not limit the division of modules or the naming of modules.

[0230] In practical implementation, if the communication interface 113, memory 112, and processor 111 are implemented independently, they can be interconnected via a bus to complete communication.
