[0046] This application provides a segmented multi-fan wire temperature control and transportation system and method. The transportation system includes a main control module and multiple sequentially arranged roller conveyor sections. Each roller conveyor section corresponds to a fan group, and each fan group includes at least one fan.

Based on this structure, the main control module determines the operating frequency of the fan group corresponding to each roller conveyor section based on the acquired target temperature drop rate, actual temperature drop rate, and temperature drop rate change trend. First, this application, through a segmented control architecture, sets at least two temperature detection points in each roller conveyor section, forming an independent control closed-loop subsystem based on each roller conveyor section. This achieves real-time and precise monitoring of the wire cooling process, enabling the fan group corresponding to each roller conveyor section to independently adjust its operating frequency according to the cooling needs of that section, improving the system's flexibility and adaptability to changes in local operating conditions. Secondly, by analyzing the target temperature drop rate, the actual temperature drop rate, and their trends, the main control module has shifted from passive feedback to active prediction. It can predict the future temperature trend of the coil and adjust the fan frequency in advance, effectively reducing the lag in system feedback and significantly improving control accuracy. This system cleverly balances the contradiction between control accuracy and complexity, achieving precise control with only a few key parameters. The control logic is clear and concise, and the relative independence of each segment reduces the difficulty of system debugging and maintenance, improving the overall system reliability while ensuring excellent control performance.

[0063] 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

[0064] 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.

[0065] The following is an explanation of some of the terms used in this application:

[0066] Wire rod: Wire rod usually refers to hot-rolled round steel or shaped steel with a diameter of 5-22mm. Because it is delivered in coil form, it is also commonly known as wire rod.

[0067] Wire coiling: Wire coiling refers to the process of coiling high-speed wires after they have come out of the finishing mill into a coil shape through a wire coiling machine. The resulting coiled wire is also called a coil.

[0068] 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.

[0069] Coil: In the steel processing industry, "coil" refers to the process and finished product state of processing steel into a disc or coil shape using specific equipment.

[0070] Coil: refers to the finished or semi-finished product of steel rolled into a spiral shape. It is the basic form for subsequent processing. Coil is looser than coil structure and is also known as "loose coil".

[0071] In the steel metallurgy industry, after wire rod is rolled, it undergoes a long roller conveyor transport process accompanied by temperature-controlled cooling. The cooling process is a key technological step that determines its metallographic structure and mechanical properties. After the steel wire coil is ejected from the coiler, it needs to undergo a precisely controlled cooling process to obtain the required microstructure and comprehensive mechanical properties.

[0072] Most existing wire rod temperature control and transportation systems use fixed preset parameters for temperature and transportation control, lacking the ability to adapt to dynamic changes. During the steel production process, the temperature of wire rod is affected by various factors such as ambient temperature, wire rod specifications, and transportation speed. Fixed parameter temperature control methods are difficult to meet the diverse requirements of actual transportation scenarios.

[0073] Some transportation systems have attempted to introduce real-time monitoring and control, but still face the technical challenge of control lag. Existing transportation systems typically only detect temperature and adjust cooling parameters after the cable reaches a specific location, resulting in significant response delays. By the time the system detects an abnormal temperature and adjusts the fan power, the cable has already moved a certain distance, causing a mismatch between control actions and actual cooling requirements.

[0074] Existing technologies that attempt to improve temperature control often result in overly complex control logic. For example, complex models are used to obtain the operating parameters of fans and roller conveyors based on multiple parameters. While this approach can improve the accuracy of temperature control, it also increases computing power consumption and system operating costs, reduces system reliability, and increases the system failure rate.

[0075] In summary, existing wire temperature control and transportation technologies have three core limitations: First, they lack flexibility, as fixed-parameter control systems struggle to adapt to varying conditions during production, leading to unstable wire quality. Second, they have poor real-time performance, with a time lag between control actions and actual cooling requirements, affecting temperature control accuracy. Third, they are complex systems, as advanced control methods, while improving control accuracy to some extent, increase system complexity and failure rate.

[0076] In view of this, this application provides a segmented multi-fan wire temperature control transportation system and method. This system employs a segmented, separate control approach, dividing the entire wire transportation link into multiple roller conveyor sections, and individually controlling the fans in each roller conveyor section. The control process determines the operating frequency of the fans corresponding to each roller conveyor section based on the temperature drop rate of the target coil, the actual temperature drop rate, and the trend of the temperature drop rate change. Segmented, separate control improves the flexibility and accuracy of temperature control throughout the wire transportation process. Furthermore, the method of determining the fan operating frequency in real time based on the temperature drop rate change trend allows for prediction of the wire's cooling behavior in subsequent roller conveyor sections based on the predictive attribute of this parameter for the actual temperature drop rate, enabling advance adjustment of fan parameters and effectively solving the control lag problem. Moreover, the entire control logic is simple, improving system usability and enhancing the quality of the final obtained coil, better meeting user needs.

[0077] 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. The embodiments of this application will be described below with reference to the accompanying drawings.

[0078] Figure 1 A structural schematic diagram of the first segmented multi-fan wire temperature-controlled transport system provided in this application is shown below. Figure 1 As shown, the system includes a main control module ( Figure 1 (Not shown in the image), and multiple sequentially arranged roller conveyor sections 1, each roller conveyor section 1 corresponding to a fan group 2, each fan group 2 including at least one fan 21, and each roller conveyor section 1 corresponding to at least two temperature detection points 3 arranged along the conveyor transport direction. It should be understood that... Figure 1 This is a schematic diagram illustrating a transportation system comprising four roller conveyor sections 1, each fan unit 2 comprising two fans 21, and each roller conveyor section 1 corresponding to two temperature detection points 3. This schematic diagram is for illustrative purposes only and is not intended to limit the specific implementation of this application.

[0079] The aforementioned main control module can be any module with control functions, such as a control chip. When the main control module includes a control chip, this application does not limit the type of control chip; those skilled in the art can choose according to their needs. For example, the main control module can use a high-performance PLC or an industrial microcontroller as the core processor, responsible for data acquisition, logic operations, and control instruction output. It should be noted that the control function mentioned here refers to the function of controlling the operation of other modules connected to the main control module by sending control signals.

[0080] The aforementioned sequentially arranged roller conveyor sections 1 constitute the roller conveyor used for transporting the target coil. The roller conveyor section 1 referred to here can be an independent roller conveyor section 1 whose transport speed can be controlled individually, or it can be a complete roller conveyor divided into multiple areas, each area serving as a roller conveyor section 1. This application does not limit the length of each roller conveyor section 1; the lengths of different roller conveyor sections 1 can be the same or different. The aforementioned target coil can be any coil requiring temperature-controlled cooling during transport.

[0081] This application does not limit the location of the fan unit 2 corresponding to the roller conveyor section 1; it can be on the platform or off the platform. The number of fans 21 included in each fan unit 2 can be the same or different.

[0082] The aforementioned temperature detection point 3 is used to detect the temperature of the target coil transported by the roller conveyor. The temperature measuring devices corresponding to different temperature detection points 3 can be the same or different; for example, they can be infrared thermometers or K-type thermocouples. One temperature detection point 3 can correspond to multiple temperature measuring devices or one temperature measuring device; this application does not limit this. This application does not limit the specific detection location of the temperature detection point 3 within a roller conveyor section 1. For example, each roller conveyor section 1 can correspond to 3 temperature detection points 3, with one temperature detection point 3 located at the entrance of roller conveyor section 1, one temperature detection point 3 located at the exit of roller conveyor section 1, and one temperature detection point 3 located in the middle of roller conveyor section 1. The relative positions of the temperature detection points 3 in different roller conveyor sections 1 can be the same or different.

[0083] Based on the above structure, this application provides a segmented multi-fan 21 wire temperature control transportation method, which is applied to the main control module of the segmented multi-fan 21 wire temperature control transportation system. Figure 2 A flowchart illustrating the first segmented multi-fan wire temperature-controlled transportation method provided in this application is shown below. Figure 2 As shown, the method may include the following steps:

[0084] S101. Obtain the target temperature drop rate of the target coil corresponding to each roller section.

[0085] The target temperature drop rate mentioned here refers to the rate at which the target coil needs to maintain a temperature drop in each roller section 1. It can be a single value or a range. This application does not limit its specific value, and those skilled in the art can set it as needed.

[0086] One possible implementation is that the main control module can obtain the target temperature drop rate of the target coil requiring temperature control and cooling, as input by the user, for each roller section 1. For example, the main control module may include a user interface, based on which the user-input target temperature drop rate for each roller section 1 is obtained.

[0087] Another possible implementation is that the main control module can first obtain the type of the target coil; then, based on the type of the target coil, determine the target temperature drop rate corresponding to each roller section 1 when transporting the target coil on the roller conveyor.

[0088] For example, the main control module can directly obtain the type of target coil input by the user, or it can obtain the type of target coil input by other devices, such as computers, mobile phones, tablets, and remote controls. The main control module 1 can, for example, store the mapping relationship between the type of target coil and the target temperature drop rate of the target coil corresponding to each roller section 1. After obtaining the type of target coil, the main control module determines the target temperature drop rate of the target coil corresponding to each roller section 1 based on the type of target coil and the above mapping relationship. Through this implementation, the target temperature drop rate can be determined for each roller section 1 without requiring the user to manually input it; only the type of target coil is needed to determine the target temperature drop rate, simplifying the operation, improving ease of use, and enhancing the user experience.

[0089] It should be noted that this step can be performed before step S102, simultaneously with step S102, or after step S102. This application does not limit it.

[0090] S102. Use temperature detection points to obtain the actual temperature drop rate of the target coil as it is transported through each roller section.

[0091] In this step, the main control module acquires the real-time temperature of the target coil sent by temperature detection point 3. This application does not limit the period during which temperature detection point 3 detects the temperature of the target coil.

[0092] For example, for a roller conveyor section 1, the main control module can subtract the temperature detected by the temperature detected by the temperature detected by the temperature detected by the temperature detected by the temperature detected by the temperature detected by the temperature detected by the temperature detected by the temperature detected by the temperature detected by the coil from ...

[0093] The main control module can, for example, calculate the time difference between the location of the target coil being measured and the time difference between the two temperature detection points 3, based on the transport speed of the roller section 1 and the distance between the two temperature detection points 3.

[0094] S103. Based on the actual temperature drop rate, determine the temperature drop rate trend of the target coil corresponding to each roller section in real time.

[0095] The temperature drop rate trend of the target coil corresponding to each roller section 1 can be represented, for example, by the time-based rate of change of the actual temperature drop rate n times before the current moment corresponding to each roller section 1, where n is an integer greater than 1.

[0096] For example, the main control module may store the temperature drop rate of each roller section 1 in each calculation cycle, and then calculate the temperature drop rate change trend of the target coil corresponding to each roller section 1 at the current moment according to the above method.

[0097] Alternatively, the trend of temperature drop rate can be represented by the temperature drop acceleration of the target coil corresponding to each roller section 1. For example, taking a temperature detection point 3 set at the inlet, middle and outlet of each roller section 1, and the target coil being transported at a constant speed in each roller section, the main control module can calculate the approximate temperature drop acceleration of the target coil corresponding to each roller section 1 according to formula (1), as the trend of temperature drop rate of that roller section.

[0098] Formula (1):

[0099] in, The temperature of the target coil at the target position when it passes through temperature detection point 3 at the entrance of the i-th roller section 1. The temperature of the target coil at the target position when it passes through temperature detection point 3 at the exit of the i-th roller section 1. The temperature of the target coil when it passes through temperature detection point 3 in the middle of the i-th roller section 1. The time required for the target coil to move from the inlet temperature detection point 3 to the outlet temperature detection point 3. This is the approximate temperature drop acceleration of the target coil in the i-th roller section 1, reflecting the changing trend of the temperature drop rate. The target position mentioned here can be any position of the target coil. It should be understood that the above formula (1) is only an example, and this application does not limit whether those skilled in the art can calculate the temperature drop acceleration of the target coil corresponding to each roller section 1 based on other formulas in specific implementation.

[0100] S104. Based on the target temperature drop rate, actual temperature drop rate, and temperature drop rate change trend of each roller conveyor section, determine the operating frequency of the fan unit corresponding to each roller conveyor section.

[0101] In this step, the main control module determines the operating frequency of the fan 21 of the fan group 2 corresponding to each roller section 1 based on the target temperature drop rate, the actual temperature drop rate, and the temperature drop rate change trend, so that the operation of the fan 21 can be controlled based on the determined operating frequency of the fan 21 in the future.

[0102] Optionally, the main control module can store a mapping relationship between the target temperature drop rate, actual temperature drop rate, and temperature drop rate variation trend of the target coil corresponding to each roller conveyor segment 1, and the operating frequency of the fan 21 of the fan group 2 corresponding to each roller conveyor segment 1. Based on the target temperature drop rate, actual temperature drop rate, and temperature drop rate variation trend of the target coil corresponding to each roller conveyor segment 1, and the aforementioned mapping relationship, the main control module determines the operating frequency of the fan 21 of the fan group 2 corresponding to each roller conveyor segment 1.

[0103] Optionally, the main control module can calculate the difference between the target temperature drop rate and the actual temperature drop rate for each roller conveyor segment 1. Then, based on this difference and the temperature drop rate trend of the target coil for each roller conveyor segment 1, the operating frequency of the fan 21 of the fan unit 2 corresponding to each roller conveyor segment 1 is determined. For example, the main control module can store the difference between the target coil for each roller conveyor segment 1, the temperature drop rate trend, and the mapping relationship between them and the operating frequency of the fan 21 of the fan unit 2 corresponding to each roller conveyor segment 1. Then, based on the above difference, the temperature drop rate trend, and the above mapping relationship, the operating frequency of the fan 21 of the fan unit 2 corresponding to each roller conveyor segment 1 is determined.

[0104] In this embodiment, the transport system includes a main control module and multiple sequentially arranged roller conveyor sections 1. Each roller conveyor section 1 corresponds to a fan group 2, and each fan group 2 includes at least one fan 21. Each roller conveyor section 1 corresponds to at least two temperature detection points 3 arranged along the conveyor transport direction. The roller conveyor section 1 is used to transport the target coil. Based on this structure, the main control module determines the operating frequency of the fan 21 of the fan group 2 corresponding to each roller conveyor section 1 based on the acquired target temperature drop rate, actual temperature drop rate, and temperature drop rate change trend.

[0105] First, the system provided in this embodiment uses segmented control, setting at least two temperature detection points 3 in each roller conveyor section 1 to achieve real-time and precise monitoring of the wire cooling process, establishing a complete temperature change data chain, and forming an independent control closed-loop subsystem based on each roller conveyor section 1. The fan unit 2 corresponding to each roller conveyor section 1 can be independently adjusted according to the cooling needs of this section, greatly improving the system's flexibility and adaptability. When the cooling effect of a certain roller conveyor section 1 deviates from expectations, the system can immediately adjust the operating frequency of the corresponding fan unit 2 without affecting the working status of other sections.

[0106] The segmented control architecture adopted in this system effectively balances the contradiction between centralized control and distributed execution. The main control module is responsible for overall coordination and target setting, while each roller conveyor segment 1 implements a relatively independent control cycle according to its own conditions. This architecture is similar to a distributed intelligent system, which ensures the consistency of the overall process while giving each segment the ability to adapt to changes in local conditions.

[0107] Secondly, the main control module of this application can determine whether the current cooling intensity is appropriate and the possible changes in wire temperature in subsequent processes by analyzing the difference between the actual temperature drop rate and the target value, as well as the direction of change of the temperature drop rate (accelerated cooling or decelerated cooling). This trend prediction-based control strategy is similar to neural network optimization control technology, but this system applies it to the control of segmented fans 21, achieving more precise regulation.

[0108] This application introduces temperature drop rate trend analysis, realizing a shift from passive feedback to active prediction. By analyzing the temperature drop rate trend, the main control module can predict the future trend of the target coil temperature. When the temperature drop rate is detected to be lower than the target value, the main control module can increase the frequency of the current segment of fan 21, and can further adjust the operating frequency of fan 21 according to the temperature drop rate trend. For example, when the temperature drop rate changes rapidly, the amplitude of the fan 21 operating frequency adjustment can be appropriately reduced to reduce system feedback lag and improve control accuracy.

[0109] Furthermore, this invention resolves the contradiction between control precision and control complexity. In existing technologies, improving control precision often means increasing system complexity, such as the use of multi-parameter coordinated control or complex neural network algorithms in some systems. This invention achieves precise control without significantly increasing system complexity through a segmented structure and multi-detection point design. Each roller conveyor segment 1 only needs to determine the operating frequency of the fan 21 based on a few key parameters (i.e., target temperature drop rate, actual temperature drop rate, and trend of change), making the control logic clear and concise. Simultaneously, because each segment is relatively independent, system debugging and maintenance are simpler. This design ensures both control effectiveness and improved system reliability.

[0110] The following is an example of how the main control module determines the operating frequency of the fan 21 of the fan unit 2 corresponding to each roller conveyor section 1.

[0111] One possible implementation method, Figure 3 A flowchart illustrating the second segmented multi-fan wire temperature-controlled transportation method provided in this application is shown below. Figure 3 As shown, step S104 may include, for example, the following steps:

[0112] S201. Based on the target temperature drop rate and the actual temperature drop rate corresponding to each roller conveyor section, determine the initial operating frequency of the fan unit corresponding to each roller conveyor section.

[0113] One possible implementation is that the main control module obtains the difference between the target temperature drop rate and the actual temperature drop rate for each roller conveyor segment 1. Then, based on this difference, it determines the initial operating frequency of the fan 21 of the fan unit 2 corresponding to each roller conveyor segment 1.

[0114] For example, the main control module can determine the initial operating frequency of the fan 21 of the fan group 2 corresponding to each roller conveyor segment 1 based on the difference and the operating frequency of the fan 21 of the fan group 2 corresponding to each roller conveyor segment 1 at the current moment. For example, the main control module can store the mapping relationship between the above difference and the fan 21 operating frequency adjustment amount. The main control module determines the adjustment amount of the fan 21 operating frequency corresponding to each difference based on the above difference for each roller conveyor segment 1 and the above mapping relationship. Then, by adding the corresponding fan 21 operating frequency adjustment amount to the current operating frequency of the fan 21 corresponding to each roller conveyor segment 1, the initial operating frequency of the fan 21 of the fan group 2 corresponding to each roller conveyor segment 1 is obtained.

[0115] Another possible implementation is that the main control module can, for example, adjust the actual temperature drop rate of each roller section 1 based on the target temperature drop rate, the actual temperature drop rate, and the current operating frequency of the corresponding fan 21, using the actual temperature drop rate as the adjustment target, and adopt PID control to use the adjusted operating frequency of the fan 21 as the initial operating frequency of the fan 21. Specific implementation methods can refer to existing technologies and will not be elaborated here.

[0116] Another possible implementation is that the main control module can store a mapping relationship between the target temperature drop rate, the actual temperature drop rate, and the initial operating frequency of the fan 21 of the fan group 2 corresponding to each roller conveyor segment 1. The main control module determines the initial operating frequency of the fan 21 of the fan group 2 corresponding to each roller conveyor segment 1 based on the acquired target temperature drop rate, actual temperature drop rate, and the above mapping relationship.

[0117] This application does not limit the way the above mapping relationship is obtained; for example, it can be obtained through offline calibration.

[0118] S202. Based on the temperature drop rate change trend of each roller conveyor section, determine the operating frequency adjustment coefficient of the fan unit corresponding to each roller conveyor section.

[0119] One possible implementation is that the main control module stores a mapping relationship between the temperature drop rate change trend and the adjustment coefficient. For example, the main control module can determine the adjustment coefficient of the fan 21 of the fan group 2 corresponding to each roller section 1 based on the temperature drop rate change trend corresponding to each roller section 1 and the mapping relationship.

[0120] This application does not limit the way the above mapping relationship is obtained; for example, it can be obtained through offline calibration.

[0121] S203. Determine the operating frequency of each fan based on its initial operating frequency and the corresponding adjustment coefficient.

[0122] The main control module determines the operating frequency of each fan 21 based on its initial operating frequency and adjustment coefficient, and the method for determining the adjustment coefficient is related to this method. For example, if the mapping relationship between the temperature drop rate change trend and the adjustment coefficient in step S202 is determined by offline calibration, then the implementation method of this step is related to the offline calibration method of the above mapping relationship.

[0123] For example, if the adjustment coefficient is used as a multiplier during the offline calibration process, the main control module can multiply the initial operating frequency of each roller section 1 by the corresponding adjustment coefficient to obtain the operating frequency of the corresponding fan 21.

[0124] Alternatively, if the adjustment coefficient is used as an addend during the offline calibration process, the main control module can use the initial operating frequency of each roller section 1 plus the corresponding adjustment coefficient to obtain the operating frequency of the corresponding fan 21.

[0125] In this embodiment, the main control module first determines the initial operating frequency of the fan 21 of the fan group 2 corresponding to each roller conveyor segment 1 based on the target temperature drop rate and the actual temperature drop rate. Then, based on the temperature drop rate change trend corresponding to each roller conveyor segment 1, it determines the operating frequency adjustment coefficient of the fan 21 of the fan group 2 corresponding to each roller conveyor segment 1. Finally, based on the initial operating frequency of each fan 21 and the adjustment coefficient, it determines the operating frequency of each fan 21.

[0126] The scheme in this embodiment determines the "initial operating frequency" based on the deviation between the target value and the actual value, thus forming a fast-response feedforward control; combined with the "adjustment coefficient" based on the trend of temperature drop rate change, feedback correction is performed to form a composite control loop, which overcomes the lag of a pure feedback system.

[0127] Furthermore, this application can predict the temperature drop rate by observing the trend of the temperature drop rate change. This predictive method effectively prevents the temperature from deviating excessively from the set value (overshoot), ensuring that the temperature drop rate of the target coil smoothly approaches the target temperature drop rate. Compared to directly making large frequency jumps based on instantaneous temperature differences, this "reference value + fine-tuning" method makes the change in the operating frequency of the fan 21 smoother and more gradual. This reduces the impact on the fan 21 motor and frequency converter, lowers the mechanical and electrical losses of the equipment, and extends its service life.

[0128] Optionally, in some embodiments, each roller conveyor segment 1 may also correspond to a local control module, which is used to obtain control commands input by the user and control the operation of the corresponding fan unit 2 according to the control commands.

[0129] The aforementioned control commands may include, for example, one or more of the following: switching commands, fan 21 operating frequency configuration commands, etc. The aforementioned switching commands, for example, can control the switching on / off of the corresponding fan 21.

[0130] For example, the local control module may include a user interface through which it obtains control commands input by the user. The user interface may be a remote control, computer, mobile phone, tablet, or other terminal.

[0131] This implementation method increases the control channels of the entire transportation system. When the remote control method of the main control module fails, the operator can directly control the operation of the fan unit 2 corresponding to each roller section 1 through the local control module, avoiding the paralysis of the operation of the fan 21 of the entire transportation system due to the communication failure of the main control module, and improving the stability and robustness of the transportation system.

[0132] Optionally, the transportation system may include a local mode and a remote mode. In remote mode, the main control module is responsible for controlling the operation of each fan 21; in local mode, the local control module controls the operation of the fan 21. For example, if the remote mode fails, the system automatically switches to local mode, and the local control module controls the operation of the fan 21 based on the control commands input by the user. If the remote mode failure is resolved, the operator can, for example, select to switch back to remote mode through the main control module's operating interface, and the main control module controls the operation of the fan 21.

[0133] In this embodiment, operators can independently control the start-up, shutdown, and operating frequency of each fan 21 through the operating interface of each local control module. This design achieves fault isolation, meaning that the commissioning or maintenance of a single fan 21 in a single roller conveyor section 1 will not affect the normal operation of other sections, thus improving the overall control flexibility and availability of the transportation system.

[0134] Optionally, in some embodiments, the local control module may store control data during the operation of the fan 21 and send the stored control data to the main control module when switching to the main control module to achieve data sharing and support global monitoring and data analysis.

[0135] In some embodiments, each fan 21 is connected to at least one air box 4, and each air box 4 is equipped with a fan 21 operation status monitoring sensor. The aforementioned fan 21 operation status monitoring sensor may include, for example, an airflow sensor and / or an air pressure sensor. The fan 21 may be directly connected to the air box 4, or the fan 21 may be connected to the air box 4 via an air duct.

[0136] In this implementation, Figure 4The schematic diagram of the second segmented multi-fan wire temperature control and transport system provided in this application should be understood to show only a part of the segmented multi-fan 21 wire temperature control and transport system. This part only includes one roller section 1 and one fan group 2 corresponding to the roller section 1. The schematic diagram is a schematic diagram with the fan group 2 including one fan 21 as an example. Figure 5 A flowchart illustrating the third segmented multi-fan temperature-controlled transportation method for 21-wire wire provided in this application is shown below. Figure 4 and Figure 5 As shown, the method may include, for example, the following steps:

[0137] S301. Obtain the fan operating status parameters sent by the fan operating status sensor.

[0138] The operating status parameters of the aforementioned fan 21 may include, for example, the wind speed parameter and / or the wind pressure parameter of the fan 21.

[0139] In this step, the operating status sensor of the fan 21 monitors the operating status parameters of the fan 21 in real time and sends them to the main control module so that the main control module can determine the operating frequency of the fan 21 based on the operating status parameters of the fan 21.

[0140] S302. Based on the target temperature drop rate, actual temperature drop rate, fan operating status parameters, and temperature drop rate change trend of each roller conveyor section, determine the operating frequency of the fan unit corresponding to each roller conveyor section.

[0141] One possible implementation is that the main control module uses PID control based on the target temperature drop rate, actual temperature drop rate, current fan 21 operating frequency, and fan 21 operating status parameters of the target coil corresponding to each roller section 1. The actual temperature drop rate is used as the adjusted parameter, and the determined fan 21 operating frequency corresponding to each roller section 1 is used as the fan 21 operating frequency to be adjusted.

[0142] Subsequently, the main control module, referring to the method described in the above embodiment, determines the operating frequency of the fan 21 corresponding to each roller conveyor section 1 based on the initial operating frequency of the fan 21 and the trend of temperature drop rate change, substitutes the operating frequency to be adjusted into the role of the initial operating frequency, and calculates and obtains the operating frequency of the fan 21 corresponding to each roller conveyor section 1.

[0143] Another possible implementation involves the main control module using the operating frequency of the fan 21 of the fan group 2 corresponding to each roller conveyor segment 1, obtained from the target temperature drop rate, actual temperature drop rate, and temperature drop rate change trend, as described in the above embodiments, as the operating frequency to be adjusted. Subsequently, the main control module adjusts the corresponding operating frequency to be adjusted based on the operating status parameters of each fan 21 to obtain the final operating frequency of each fan 21. For example, the main control module may store a mapping relationship between the operating status parameters of the fan 21 and adjustment coefficients. The main control module determines the adjustment coefficients based on the aforementioned operating status parameters of the fan 21 and the corresponding mapping relationship. Then, the main control module determines the operating frequency of the fan 21 corresponding to each roller conveyor segment 1 based on the operating frequency to be adjusted and the adjustment coefficients. The method by which the main control module determines the operating frequency of the fan 21 corresponding to each roller conveyor segment 1 based on the operating frequency to be adjusted and the corresponding adjustment coefficients is related to the method of determining the mapping relationship between the adjustment coefficients and the operating status parameters of the fan 21. For example, if the adjustment coefficient in the mapping relationship is used as the multiplier of the operating frequency of the fan 21 to be adjusted during the offline calibration process, then the main control module will multiply the operating frequency to be adjusted corresponding to each roller section 1 by the corresponding adjustment coefficient to obtain the operating frequency of the fan 21 corresponding to each roller section 1.

[0144] In this embodiment, the main control module first acquires the operating status parameters of the fan 21 sent by the fan 21 operating status sensor. Then, based on the target temperature drop rate, actual temperature drop rate, fan 21 operating status parameters, and temperature drop rate change trend corresponding to each roller conveyor section 1, the operating frequency of the fan 21 in the fan group 2 corresponding to each roller conveyor section 1 is determined. By determining the operating frequency of the fan 21 based on the fan 21 operating status parameters, the parameter dimension can be increased, thereby further improving the accuracy and control precision of the determined fan 21 operating frequency.

[0145] In some embodiments, the fan 21 and / or the motion motor corresponding to the roller conveyor section 1 are equipped with temperature and vibration sensors. In this implementation, the main control module can also detect, for example, whether the operation of the roller conveyor and / or the fan 21 is abnormal. For example, Figure 6 A flowchart illustrating the fourth segmented multi-fan wire temperature-controlled transportation method provided in this application is shown below. Figure 6 As shown, the method may include, for example, the following steps:

[0146] S401. Obtain the temperature and vibration parameters sent by the temperature and vibration sensor.

[0147] The aforementioned temperature vibration parameters include both temperature parameters and vibration parameters.

[0148] In this step, the main control module acquires the temperature and vibration parameters sent by the temperature and vibration sensor, so as to determine the operating status of the motion motor equipped with the temperature and vibration sensor.

[0149] S402. Determine the operating status of the corresponding motion motor based on the temperature and vibration parameters.

[0150] For example, the main control module may store the normal temperature range and normal vibration frequency range of the motion motor corresponding to each temperature vibration parameter. After acquiring the temperature vibration parameter, the main control module determines whether it is within the corresponding normal temperature range and normal vibration frequency range. If the temperature vibration parameter is within the corresponding normal parameter range, it is determined that the motion motor corresponding to the temperature vibration parameter is working normally; if the temperature vibration parameter is outside the corresponding normal parameter range, it is determined that the operating state of the motion motor corresponding to the temperature vibration parameter is abnormal, and step S403 is executed.

[0151] S403, outputs a warning signal.

[0152] The main control module can output warning signals through a user interface, or it can output warning signals to other electronic devices. These other electronic devices can include, for example, mobile phones, tablets, computers, and servers. The main control module can output warning signals through the user interface in any combination of one or more methods, such as text, sound, or light.

[0153] In this embodiment, the main control module first acquires the temperature and vibration parameters sent by the temperature and vibration sensor. Then, based on these parameters, it determines the operating status of the corresponding motor of the fan 21 or roller conveyor section 1, and outputs a warning signal when the operating status indicates an abnormality. Through this implementation, the main control module can monitor the operating status of the motors of the roller conveyor and / or fan 21 in real time, taking corresponding measures in advance when abnormalities may occur, reducing the possibility of a complete system failure due to malfunction, and improving system stability and availability.

[0154] Optionally, in some embodiments, at least one fan group 2 of the transport system includes multiple fans 21, which are used to cool different lateral positions of the target coil. Each fan 21 corresponds to at least two temperature detection points 3 in each roller section 1 to detect the temperature of the position cooled by the fan 21.

[0155] Different lateral positions of the coil often exhibit different temperature drop rates due to the presence of overlapping and non-overlapping points. In this embodiment, at least one fan unit 2 of the transportation system includes multiple fans 21 designed to cool different lateral positions of the target coil. Differential cooling of different lateral positions of the target coil can be achieved through differentiated control of these fans 21. Each fan 21 corresponds to at least two temperature detection points 3. The main control module independently controls each fan 21 based on feedback from its corresponding temperature detection points 3, thereby ensuring a consistent temperature drop rate for coils within the same coil, reducing performance differences within the same coil, and improving the overall quality of the target coil.

[0156] Figure 7 This is a schematic diagram of a control device provided in this application. This control device is applied to the main control module in the above embodiments, such as... Figure 7 As shown, the control device includes: a first acquisition module 11, a second acquisition module 12, a first determination module 13, and a second determination module 14.

[0160] The second determining module 14 is used to determine the operating frequency of the fan of the fan unit corresponding to each roller conveyor section based on the target temperature drop rate, the actual temperature drop rate, and the temperature drop rate change trend corresponding to each roller conveyor section.

[0161] In one possible implementation, the second determining module 14 is specifically configured to: determine the initial operating frequency of the fan unit corresponding to each roller conveyor segment based on the target temperature drop rate and the actual temperature drop rate; determine the adjustment coefficient of the operating frequency of the fan unit corresponding to each roller conveyor segment based on the temperature drop rate change trend; and determine the operating frequency of each fan based on the initial operating frequency of each fan and the corresponding adjustment coefficient.

[0165] One possible implementation is that each fan is connected to at least one air box, and each air box is equipped with a fan operation status monitoring sensor; a third acquisition module is used to acquire the fan operation status parameters sent by the fan operation status monitoring sensor; a second determination module 14 is specifically used to determine the operating frequency of the fan in the fan group corresponding to each roller conveyor section based on the target temperature drop rate, the actual temperature drop rate, the fan operation status parameters, and the temperature drop rate change trend corresponding to each roller conveyor section.

[0166] One possible implementation is that the fan operating status parameters include the fan speed parameter and / or the fan pressure parameter.

[0167] In one possible implementation, the fan and / or the motion motor corresponding to the roller conveyor section is equipped with a temperature and vibration sensor. A fourth acquisition module is used to acquire the temperature and vibration parameters sent by the temperature and vibration sensor; determine the operating status of the corresponding motion motor based on the temperature and vibration parameters; and output a warning signal if the operating status indicates an abnormality.

[0168] In one possible implementation, at least one of the fan units includes multiple fans, each fan being used to cool different lateral positions of the target coil. Each fan corresponds to at least two temperature detection points in each roller conveyor section for detecting the temperature of the position cooled by the fan.
