Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of copper-clad aluminum enameled wire production, and particularly relates to a steam protection dynamic adjustment method for copper-clad aluminum enameled wire production. BACKGROUND

[0002] As a kind of composite conductor material with high conductivity of copper and lightweight economy of aluminum, copper-clad aluminum enameled wire is widely used in the fields of motor, transformer and high-frequency electronic device, etc. In its production process, enameled wire needs to go through wire drawing, annealing, painting, curing and other processes. The high-temperature annealing and paint film curing stages are extremely sensitive to environmental temperature and humidity. In order to prevent wire oxidation, paint film blistering or adhesion reduction at high temperature, a steam protection system is usually introduced in the key production section. The steam execution unit supplies saturated steam to the furnace or specific area to form an inert or reducing microenvironment, so as to ensure product quality.

[0003] At present, the steam protection control in the copper-clad aluminum enameled wire production line mostly adopts fixed mode or manual intervention strategy. Specifically, after a product specification or process route is determined, an operator sets a fixed steam supply parameter (such as pressure, flow, action section and start-stop timing) according to experience or process procedure in advance, and maintains it unchanged during the whole batch production. When it is necessary to switch to different wire diameter, paint type or annealing curve, the flexibility of steam protection control is not enough, which leads to increased quality risk due to protection failure.

[0020] At present, the steam protection control in the copper-clad aluminum enameled wire production line mostly adopts fixed mode or manual intervention strategy. Specifically, after a product specification or process route is determined, an operator sets a fixed steam supply parameter (such as pressure, flow, action section and start-stop timing) according to experience or process procedure in advance, and maintains it unchanged during the whole batch production. When switching to different wire diameters, paint types or annealing curves is needed, the flexibility of steam protection control is not enough, leading to increased quality risk of protection failure.

[0021] To solve the above problems, the application embodiment provides a steam protection dynamic adjustment method for copper-clad aluminum enameled wire production. In this method, by obtaining the current process condition and matching the initial control scheme, it can be ensured that the steam protection is highly adapted to the current production state. When receiving a process switching instruction, the target control scheme is obtained in time, so that the steam execution unit can smoothly transition to the new working mode during the process switching process, avoiding control delay or uncoordinated phenomenon. After confirming the difference between the two, the execution unit parameters are adjusted in advance before switching the working mode, avoiding protection interruption or over-protection, realizing flexible control of steam protection, and significantly improving product quality consistency and energy utilization efficiency.

[0022] The copper-clad aluminum enameled wire production steam protection dynamic adjustment method provided by the embodiments of the present application can be applied to an electronic device, and at this time, the electronic device is the execution subject of the copper-clad aluminum enameled wire production steam protection dynamic adjustment method provided by the embodiments of the present application, and the embodiments of the present application do not make any limitation on the specific type of the electronic device.

[0023] It can be understood that the electronic device can be various smart devices with a display screen and interactive capability. For example, the electronic device can be a terminal device such as a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), and a desktop computer.

[0024] In order to better understand the copper-clad aluminum enameled wire production steam protection dynamic adjustment method provided by the embodiments of the present application, the specific implementation process of the copper-clad aluminum enameled wire production steam protection dynamic adjustment method provided by the embodiments of the present application is exemplarily introduced below.

[0025] Figure 1 A schematic flowchart of the copper-clad aluminum enameled wire production steam protection dynamic adjustment method provided by the embodiments of the present application is shown, Figure 2 A principle schematic diagram of the copper-clad aluminum enameled wire production steam protection dynamic adjustment method provided by the embodiments of the present application is shown, and the copper-clad aluminum enameled wire production steam protection dynamic adjustment method comprises: S100, a current process condition in a copper-clad aluminum enameled wire production process is acquired; wherein a protection scheme corresponding to the current process condition is an initial control scheme, and the initial control scheme is used to control a steam execution unit to operate in a first working mode to provide steam protection for a production line.

[0026] It can be understood that the current process condition refers to the multi-dimensional running state set of the copper-clad aluminum enameled wire in the actual continuous production process, which is directly related to the conductor coating quality, the curing effect of the paint film and the thermal stability of the wire core. It is composed of specific data of sensor, execution unit feedback signal and environmental parameter in different areas of the production line. Due to the extremely sensitive thermal field distribution of the enameled wire production process, the steam protection system plays an important role in stabilizing the wire core temperature, maintaining the curing environment of the paint film, and avoiding the oxidation of the aluminum core. Therefore, real-time perception of the process condition must have high resolution, high stability and low delay characteristics. Specifically, the current process condition usually includes real-time temperature, humidity, steam pressure, conductor drawing speed, wire laying tension, traction speed, baking section negative pressure condition, instantaneous flow of steam nozzle, actual steam supply temperature curve and compensation parameters of the surrounding environment of the production line, such as ambient temperature, humidity, burner working state, etc. Industrial systems can collect process condition data in real time through temperature sensors, mass flow meters, pressure sensors, optical fiber temperature measurement probes, torque sensors and other hardware, and transmit them to the control center through bus protocols (such as Modbus, CANopen or EtherCAT).

[0027] The initial control scheme is the steam protection configuration adopted by the production line by default under the current process condition, which is used to ensure that the copper-clad aluminum wire core does not oxidize, delaminate, soften or degrade in performance during the heating stage, and the steam execution unit operates according to the first working mode. The first working mode usually refers to the system operating according to the established steam supply strategy under standard production conditions, such as maintaining a certain set pressure range, fixed injection frequency or maintaining stable steam flow based on PID control. Because copper-clad aluminum materials have large thermal expansion coefficient difference, high thermal conductivity and easy oxidation, if the steam protection fluctuates too much, it may cause quality defects such as bubbles, pinholes and poor adhesion of the paint film. Therefore, the initial control scheme not only is a strategy, but also substantially restricts the specific behavior of the steam execution unit, including start-stop logic, temperature following strategy, load response mode, etc.

[0028] S200, in response to the received process switching instruction, obtaining a target control scheme; wherein the target control scheme is a control scheme corresponding to the target condition after the change of the process condition, and the target control scheme corresponds to a second working mode enabled by the steam execution unit after ending the first working mode.

[0029] It can be understood that the process switching instruction is a control trigger signal issued by the production scheduling system when the copper-clad aluminum enameled wire production process is adjusted, quality compensated or environment adapted, and its essence is to switch the control system from the current thermal protection strategy to the new working condition protection rule, so as to cope with the influence of production speed change, wire diameter change, paint variety change or environmental disturbance. Since the enameled wire production process has strong coupling and obvious thermal hysteresis characteristics, any change of process working condition will directly affect the heat absorption effect of the wire core and the curing speed of the paint film, therefore, when the control system receives the process switching instruction, the target control scheme corresponding to the target working condition must be read immediately, so as to avoid the non-linear drift of the wire core temperature or the unstable transition of the steam humidity due to the response delay. The target control scheme is a complete control model matched with the new process rhythm or environmental condition, which not only includes the state information of whether the steam execution unit is enabled, but also includes the steam pressure bias, steam temperature curve, injection interval, humidity interval, thermal load adjustment mode and other detailed parameters. Compared with the initial control scheme, the target control scheme is generated in the context of process optimization or working condition mutation, and is used to ensure that the steam protection system can still maintain the thermal stability of the wire core and the curing consistency of the paint film under the new production condition.

[0030] When the target control scheme is obtained, whether the steam execution unit needs to be switched from the first working mode to the second working mode can be confirmed by performing a parameter loading and verification process and comparing the differences between the initial control scheme and the target control scheme. The second working mode can be understood as a control strategy adapted to the characteristics of the new production stage, for example, starting part of the standby steam injection device, using enhanced PID logic, using zoned steam supply mode, or dynamically following the steam pressure curve, to ensure that the target working condition can quickly establish the required thermal and humid environment. In specific implementation, the data structure of the target control scheme can be parsed from the configuration database or the prediction model, including parameter table, execution logic, associated executor list and safety limit condition, and then injected into the drive module of the steam execution unit.

[0031] In one possible implementation, the initial control scheme includes a control instruction to disable the steam execution unit in the production process; before switching the steam execution unit from the first working mode to the second working mode, the method further comprises: S400, according to the control instruction of the initial control scheme to disable the steam execution unit in the production process, controlling the steam execution unit to stop steam supply in the specified production section.

[0032] It can be understood that the steam execution unit undertakes the function of providing necessary wet heat protection for the core in the production process of copper-clad aluminum enameled wire, including inhibiting aluminum core oxidation, improving thermal uniformity, assisting in paint film curing, etc. Therefore, stopping the steam execution unit is not a simple stop action, but a key link for reinitializing the thermal environment of the production line. In order to ensure that the stopping action does not cause thermal shock of the core, softening instability of the paint film or sudden change of local thermal gradient, a multi-stage stopping sequence can be set in the initial control scheme, such as gradually reducing the steam pressure, shortening the injection period, reducing the injection temperature or switching to the natural cooling mode, to ensure that the stopping process of the steam execution unit is smooth and controllable.

[0033] According to the stopping instruction in the initial control scheme, a power reduction or shutdown signal can be sent to the steam valve group, the injection nozzle, the pressure regulator, the steam supply branch and other components. These signals can be issued to the execution layer devices such as electric regulating valves, proportional regulating valves or electromagnetic valves through the field bus protocol.

[0034] In one possible implementation, the target control scheme contains control instructions for enabling the steam execution unit in the production process; before switching the steam execution unit from the first working mode to the second working mode, the method further comprises: S500, according to the control instruction for enabling the steam execution unit in the production process in the target control scheme, controlling the steam execution unit to start steam supply in the specified production section.

[0035] It can be understood that the control instruction for enabling the steam execution unit in the target control scheme is a set of start-up logic sequence matched with the target working condition, which includes parameters such as steam pressure setting, steam supply flow ramp curve, steam injection period, injection port opening sequence, production section matching relationship, system soft start time constant, etc., to ensure that the steam execution unit can avoid adverse phenomena such as steam instantaneous impact, pressure fluctuation, local overheating or condensate flushing during the transition from the closed state to the working state, thereby protecting the stable operation of the production line.

[0036] In actual implementation, the steam start-up model in the target control scheme can be analyzed, and the start-up parameters can be corrected in real time according to the real-time speed of the production line, the position of the target protection section, the change of the wire thermal load and the curing characteristics of the paint. For example, when the production speed increases, the residence time of the core in the hot zone is shortened, so the steam pressure or the steam supply climbing speed needs to be increased accordingly; if the paint is in the high curing energy interval, the steam temperature needs to be increased to ensure sufficient heat field compensation. Then, the system sends the start-up signal to various execution devices in the steam execution unit through the field control network, including electric pressure regulating valves, flow control valves, proportional valve groups, partition steam injection nozzles, etc., which are activated one by one according to the logic of the target control scheme, and the pressure, temperature, humidity and flow feedback data are checked in a closed loop.

[0037] S300, in the case where the initial control scheme and the target control scheme are different, adjusting the process parameters of the steam execution unit according to the target control scheme, and switching the steam execution unit from the first working mode to the second working mode.

[0038] It can be understood that after the process condition changes, the steam execution unit is switched from the protection strategy corresponding to the old condition to the protection strategy required by the new condition, so that the key environmental parameters such as the production line thermal field, humidity and steam coverage area are completely matched with the target condition. The first working mode of the steam execution unit usually corresponds to the protection logic under the initial condition, such as lower steam pressure, narrower spraying section or weaker heat load state; and the second working mode is adapted to the target condition, such as the entering of the enameled wire into the high-temperature curing stage or the high-steam compensation stage under a specific line speed, so that the steam execution unit can stably output steam in a larger heat demand range. The parameter adjustment is not only the replacement of a single parameter, but also includes the re-setting of multiple dimensions such as the steam pressure target value, the spraying period, the steam supply section selection, the actuator opening degree, the number of spraying ports and the steam dryness target.

[0039] In the traditional production process of copper-clad aluminum enameled wire, the control of the steam execution unit usually adopts a unified overall control strategy, that is, the same set of process parameters and control mode is used for the entire production line, regardless of whether there are differences in the process conditions or protection requirements of each section of the production line. Although this conventional method is simple to implement and facilitates centralized monitoring and parameter management, it has significant defects. Since the process states and heat sensitivities of different sections of the production line are different, unified control is easy to cause local process over or under. For example, the temperature sensitivity of the front forming section is high, and if a unified higher steam flow is used, it may cause local overheating or stress accumulation; when fine temperature control is required in the rear finishing section, the unified strategy may not be able to provide sufficient local adjustment capability, affecting product quality. Secondly, a single control mode cannot cope with the failure or non-operation of the actuator. Once a certain actuator fails, the control effect of the entire production line is likely to decrease, causing production interruption or process fluctuation. Thirdly, the overall control lacks flexibility and cannot implement differentiated optimization for different process stages, nor can it quickly adjust the local steam supply according to the target condition, resulting in increased energy consumption and reduced efficiency.

[0040] To solve the above problems, the method adopts the strategy of dividing the pre-production line into a first section and a second section, and designs independent protection strategies and corresponding executor types for each section. The protection strategies and corresponding executor types of the first section and the second section can be the same or different under different circumstances. The division of the first section and the second section enables the control system to adjust the steam supply and executor parameters according to the process requirements of each section, realizing local fine control. In this way, even if the executor in a certain section is unavailable or the process condition changes, the control of the other section can still be optimized independently, thereby improving the robustness and stability of the system. At the same time, the section control also supports differentiated adjustment, which can improve the steam utilization efficiency and the overall operation efficiency of the production line while ensuring safety and product quality. Therefore, compared with conventional unified control, the method solves the problems of insufficient local control, overall control failure, executor coordination difficulty, and insufficient process flexibility through sectionalization and strategy differentiation design, realizing more reliable, flexible, and efficient steam regulation and control of the production line.

[0041] The initial control scheme and the target control scheme correspond to the control strategy set under the current process condition and the expected optimized condition respectively. The first protection strategy for protecting the first section of the production line refers to a set of action sequences or rules preset for the physical or functional area numbered as the first section in the production process to ensure the safe operation, stable temperature, non-exceeding pressure limit, and non-overloading of the equipment, which can include upper limit restriction of steam quantity, trigger condition of pressure reduction action, bypass valve opening rule, etc. Similarly, the second protection strategy is a complete set of rules applied to protect the second section of the production line. The entire protection system is managed in sections, and different protection logic is adopted for each section according to its equipment type, thermal sensitivity, and steam response characteristics.

[0042] When transitioning from the current condition to the target condition, the protection scheme is switched from the initial control scheme to the target control scheme, that is, a new first and second protection strategy replaces the original strategy, so that the steam regulation not only matches the current state but also meets the new production target, such as increasing production, reducing energy consumption, or improving stability. The steam execution unit is a collection of hardware-level execution mechanisms that convert control rules in the protection strategy into actual actions. The steam execution unit is composed of two types of executors. The first type of executor is used to execute the first protection strategy, such as adjusting the opening degree of the first section steam valve group, implementing pressure relief, rapid temperature reduction, or pressure compensation, etc. The second type of executor is used to execute the second protection strategy, corresponding to the steam regulating valve, distributor, bypass switch, or condensation adjustment device of the second section, etc. The control scheme has both flexibility and real-time response capability in actual operation, thereby ensuring that the production line is always in a controllable, safe, and stable operating state under different conditions.

[0043] In the present method, the first section and the second section are not simply a spatial partition concept, but a functional operating area formed after the production line is logically divided in advance by the steam control system. The division basis can include equipment thermal response characteristics, steam demand mode, continuity of processing technology chain, degree of thermal coupling between processes, and distribution of sensitive points of safety control, etc. The significance of the division of the first section and the second section is to make the protection strategy differentiated by paragraphs. For example, the first section needs a rapid pressure reduction strategy, an over-temperature protection strategy and a dynamic bypass logic in a high-heat-sensitive environment, so the first protection strategy usually includes a fast response action, a threshold-sensitive trigger condition and a high-frequency monitoring mechanism; the second section may need a strategy to maintain stable operation, such as a slow pressure rise, a steady-state compensation or an energy optimization strategy, so the second protection strategy will be different in logic structure, trigger condition and execution mode. Since each section is responsible for actual action by different types of actuators, for example, the first section controls the steam main valve, the overheat cut-off valve or the emergency pressure relief component by the first type of actuator, and the second section controls the pressure stabilizing valve, the valve group or the condensate water regulating system by the second type of actuator, therefore, the section division also directly determines the type mapping relationship of the actuators. By dividing the production line into the first section and the second section, the system can adjust the corresponding protection strategy when the control scheme is switched, so that no matter how the production line conditions change, the steam supply, pressure stability and safety response capability of each section can be kept in the optimal state, realizing a fine, zoned and dynamically switchable steam safety control system.

[0044] The parameter adjustment strategy in the target control scheme can be automatically calculated according to real-time variables such as current production speed, wire temperature, paint film curing stage, coating process type, etc. The process parameters defined in the target control scheme can include a set of dynamic models, so that the second working mode can maintain the stability of the steam execution unit under different production conditions. For example, when the production speed increases, the steam supply in the second working mode will automatically increase to ensure that the wire can still obtain sufficient heat and humidity compensation at high speed; when the paint film is in the high-viscosity curing section, the spray port temperature or the steam pressure will be increased to compensate for the curing energy demand. After adjusting the process parameters, the mode can be switched according to the state machine logic of the target control scheme, so that the steam execution unit enters the second working mode. This switching usually accompanies a soft start and a transition section control to avoid process instability caused by pressure mutation, temperature jump or steam fluctuation during mode switching, and can ensure that the steam protection system quickly enters a new thermal environment that meets the target working condition after process switching, providing an accurate process basis for subsequent actuator cascade regulation.

[0045] In a possible implementation, the initial control scheme includes a first protection strategy for protecting the first section of the production line and a second protection strategy for protecting the second section under the current process condition; the target control scheme includes the first protection strategy for protecting the first section and the second protection strategy for protecting the second section under the target condition; the steam execution unit includes a first type of executor for implementing the first protection strategy and a second type of executor for implementing the second protection strategy; in step S300, the process parameters of the steam execution unit are adjusted according to the target control scheme, including: S310, when the first protection strategy in the initial control scheme is different from that in the target control scheme, and the second protection strategy is the same, the process parameters of the first type of executor are adjusted according to the target control scheme.

[0046] It can be understood that when the first protection strategy in the initial control scheme is different from that in the target control scheme, and the second protection strategy is the same, that is, in a specific scenario in the process condition switching of the production line, only the protection requirement of the first section changes, and the protection requirement of the second section remains unchanged, at this time, the executor type related to the first section, that is, the first type of executor, needs to be adjusted to ensure that the process switching can meet the target condition and avoid interference with the second protection strategy that remains unchanged. The first protection strategy is usually used to protect the key heat-sensitive section of the copper-clad aluminum enameled wire, such as the primary softening section, the enameled pre-solidification section, or the conductor forming section that needs to be strictly controlled in temperature and humidity, so when it changes, the production line enters a new heat load state or enameled film solidification requirement. The first type of executor corresponds to the steam valve group or the injection assembly that implements the first strategy, and the adjustment action usually involves multiple parameters such as steam pressure setting, valve opening, injection period, steam coverage area, etc.

[0047] The specific values of the new parameters, such as the target steam pressure, the steam dryness requirement, the steam injection partition combination, and the preheating section time constant, can be determined according to the target protection strategy, and then these parameters are mapped into the process control model of the first type of executor. Since the change of the first protection strategy often means the change of the heat sensitivity of the wire, such as the need for stronger steam protection or more accurate heat field control, the adjustment action needs to be accompanied by the verification of the dynamic capability of the executor, including the valve response speed, the pressure regulation capability, the injection port temperature matching degree, etc., so that the process parameters can be stably implemented by the executor at the physical level. Before adjusting the parameters, the current running state of the first type of executor is also read to avoid large-scale adjustment of the executor when it is already in the limited working zone or deviates from the stable interval. A closed-loop monitoring is constructed for the first type of executor, and whether the parameters are correctly implemented is verified through multiple signals such as pressure feedback, flow feedback, temperature sensor, steam dryness monitoring, etc., so as to ensure that the steam execution system runs smoothly after the protection strategy is switched, and interference to the second section is avoided.

[0048] Optionally, S310, when the initial control scheme is different from the first protection strategy in the target control scheme, and the second protection strategy is the same, adjusting the process parameters of the first type actuator according to the target control scheme, comprising: S311, obtaining the first type actuator list information, the first type actuator list information containing at least one first type actuator.

[0049] It can be understood that the state query instruction can be sent to all first type actuators and the response can be received in real time by relying on the device communication protocol (such as Modbus, Profibus, EtherCAT, etc.), and the current working state data of each actuator, such as pressure regulation capacity, valve opening and closing position, actuator temperature, flow output capacity, etc. can be obtained by analyzing the response data packet. The first type actuator is usually a hardware unit responsible for steam injection, steam supply or pressure regulation in a specific protection area or first section, including electric valve, proportional regulating valve, steam injection module, section steam supply distributor, etc. The first type actuator list information not only contains the number of first type actuators, but also contains the device number, installation position, covered steam supply section, actuator rated capacity, response time, valve maximum opening, injection port number, device communication address and current state record of each actuator.

[0050] S312, according to the first type actuator list information, screening the first type actuator in the first type actuator list information in a runnable state to determine as a target actuator, and adjusting the process parameters of the target actuator according to the target control scheme.

[0051] It can be understood that dynamic screening can be completed in the first type actuator list information, so that the steam execution unit only uses the first type actuator that can currently work normally, is stable in state, and meets the operation condition during the switching control strategy, thereby ensuring that the target control scheme is feasible and safe in actual production. The static attributes and dynamic states of all first type actuators can be obtained through the actuator list information, including device number, operation life, temperature condition, valve opening position feedback, execution response time delay, real-time fault code, maintenance level, etc. Then the system will analyze these parameters in the production controller in real time, and judge the actuators one by one according to the preset operation standard. The operation standard can include whether the actuator is online, whether it is in an unalarmed state, whether the execution displacement is within the adjustable range, whether the response speed meets the steam adjustment demand of the target working condition, whether the current valve position allows switching to the second working mode, etc. Only the first type actuators that meet all the conditions will be screened out and determined as target actuators, and the actuators that do not meet the conditions will maintain the current state or be marked as needing maintenance. After the target actuators are screened out, the corresponding process parameters will be adjusted according to the requirements of the target control scheme, to ensure that when the whole system switches to the new working mode, the steam supply can accurately cover the specified production section and meet the new protection strategy requirements.

[0052] Illustratively, S312, according to the first type actuator list information, the first type actuator in the running state is determined as the target actuator from the first type actuator list information, and the process parameters of the target actuator are adjusted according to the target control scheme, including: S3121, according to the first type actuator list information, the device operation state data of all first type actuators in the first type actuator list information is determined.

[0053] It can be understood that the real-time operation state data of the first type actuator can be further extracted from the first type actuator list information, which is essentially a dynamic evaluation of the health, controllability and response ability of the actuator. Since the first type actuator undertakes the steam protection function for a specific production section, the accurate acquisition of its operation state directly determines the reliability of subsequent screening and parameter adjustment. The key state data of each actuator can be read on site, which can include the current temperature of the actuator, the deviation between the actual opening and the target opening, the internal pressure, the valve core position feedback, the execution response time, whether there is a sticking phenomenon, whether the power supply signal is stable, whether it is in an alarm or warning state, whether there is a communication abnormality with the upper control system, etc. In some implementations, a health analysis model based on edge computing can also be used to model and analyze hidden indicators such as vibration, current fluctuation and temperature rise rate of the actuator, so as to identify potential faults that may affect production switching in advance.

[0054] S3122, filtering all first-type actuators in a runnable state from the first-type actuator list information based on the device running state data of each first-type actuator to determine target actuators.

[0055] It can be understood that the filtering process of actuators in a runnable state can be completed according to the obtained running state data of each first-type actuator. Since the steam execution unit must ensure the stability and accuracy of steam supply during process switching, only actuators in a completely runnable state can be included in the target actuator set. In this filtering, the actuators can generally be judged item by item according to predefined runnable criteria, which can include whether the actuator is currently online, whether its feedback signal is stable, whether there is an alarm or serious deviation, whether the actuator displacement meets the action requirement, whether the mechanical damping is within the allowed range, whether the temperature and pressure are in the safety interval, whether the communication delay is below the threshold, and the like.

[0056] S3123, adjusting the process parameters of the target actuators according to the target control scheme.

[0057] It can be understood that the target actuators filtered out can be subjected to adjustment operations of process parameters. Since different protection strategies have different requirements for steam flow, pressure, adjustment rhythm, temperature rise rate, response time, etc., after entering a new process condition, the specific control parameters of the target actuators must be reset according to the target control scheme. The process parameter resetting process is essentially a process of mapping process change requirements to the actuator action level, so not only the actuator opening setting value, steam flow target value, and pressure maintenance range need to be modified, but also the actuator valve opening and closing speed, PID control parameters, dead zone compensation parameters, and the update frequency or synchronization timing between the actuator and the upper control system can be adjusted.

[0058] S320, when the first protection strategy in the initial control scheme and the target control scheme is the same, and the second protection strategy is different, adjusting the process parameters of the first-type actuators according to the target control scheme.

[0059] It can be understood that when the first protection strategy in the initial control scheme is the same as that in the target control scheme, and the second protection strategy is different, a specific scenario is handled, that is, the initial control scheme and the target control scheme remain consistent in the first protection strategy, but there is a difference in the second protection strategy. In other words, the first section protection logic responsible for the first type of actuator does not need to be changed, and the second section protection logic responsible for the second type of actuator must be re-adjusted according to the new target working condition. In the copper-clad aluminum wire production line, the first section and the second section often bear different heating, curing or steam maintenance tasks, so the change of their protection strategies may correspond to different steam flow requirements, temperature control curve changes, steam coverage changes or protection strength adjustments. In this case, the system does not need to reconfigure the first type of actuator, but focuses on updating the process parameters of the second type of actuator.

[0060] Optionally, S320, when the first protection strategy in the initial control scheme is the same as that in the target control scheme, and the second protection strategy is different, adjusting the process parameters of the first type of actuator according to the target control scheme, comprising: S321, obtaining second type actuator list information; the second type actuator list information contains at least one first type actuator.

[0061] It can be understood that all device information currently belonging to the second type of actuator can be called from the device management center or the actuator state management module. These information are not only simple device numbers, but also a comprehensive data set containing structured state data, running parameters, device topology relationship and control mapping table, that is, second type actuator list information. The second type of actuator itself corresponds to the physical execution component implementing the second protection strategy, such as pressure stabilizing valve group, secondary regulating valve, steam distributor, condensation adjusting device, etc. for the second section steam stable control, so its list information not only contains the real-time state of the device itself, but also contains the functional coupling information between them and the first type of actuator.

[0062] S322, according to the second type actuator list information, filtering out the second type actuator in the running state from the second type actuator list information to determine the target actuator, and adjusting the process parameters of the target actuator according to the target control scheme.

[0063] It can be understood that the second type actuator in the runnable state can be screened from the second type actuator list information according to the second type actuator list information, and it is determined as the target actuator, and the process parameters corresponding to the actuator are adjusted according to the target control scheme. The runnable state does not only mean that the equipment is in the state of starting or being communicable, but also a comprehensive judgment result, which can include real-time health data of the actuator, current temperature and pressure bearing capacity, valve opening and closing speed, actuator response time, fault record, calibration result and matching degree with the current steam flow demand. The running ability of the second type actuator in the list can be evaluated one by one, and the equipment with abnormality, in the protection locking state, in the maintenance mode state or with insufficient performance is filtered out, and finally a candidate set is formed, and the target actuator most suitable for undertaking the regulation and control task is selected according to the demand of the target control scheme. The process of adjusting the process parameters according to the target control scheme is not simply writing values, but dynamic calculation combined with the steam pressure model, the flow prediction model and the protection strategy condition, including setting a new opening interval of the actuator valve, adjusting the differential pressure target, setting an expected flow rate of change or defining a new adjustment response curve, so that it can accurately complete the protection action and ensure the thermal stability of the second section under the new working condition.

[0064] S330, when the first protection strategy and the second protection strategy in the initial control scheme and the target control scheme are different, adjusting the process parameters of the first type actuator and the second type actuator according to the target control scheme.

[0065] It can be understood that when the first protection strategy and the second protection strategy in the initial control scheme and the target control scheme are different, that is, the case of double changes of the protection strategy, the first protection strategy and the second protection strategy in the initial control scheme and the target control scheme are different, at this time, the protection execution system of the two sections must be adjusted at the same time, therefore, the process parameters of the first type actuator and the second type actuator can be adjusted according to the target control scheme.

[0066] Exemplarily, S330, when the first protection strategy and the second protection strategy in the initial control scheme and the target control scheme are different, adjusting the process parameters of the first type actuator and the second type actuator according to the target control scheme, comprising: S331, when the first protection strategy and the second protection strategy in the initial control scheme and the target control scheme are different, obtaining first type actuator list information and second type actuator list information.

[0067] It can be understood that when the protection strategy changes twice, that is, the first protection strategy and the second protection strategy in the initial control scheme and the target control scheme are different, at this time the protection execution system of the two sections must be adjusted. At this time, the information called is the first type actuator list information and the second type actuator list information, so as to not only include the real-time state of each type of actuator, but also include the corresponding section load prediction, steam demand curve, adjustment capacity model, possible limit operation parameters and cross-section coupling information of each actuator, for example, the action of some first type actuators may directly affect the steam pressure distribution of the second section. It must be ensured that the device data of the two sections are aligned in time stamp to avoid the deviation of strategy decision caused by asynchronous sampling.

[0068] S332, according to the first type actuator list information and the second type actuator list information, all first type actuators in the first type actuator list information in a running state are determined as first target actuators, and all second type actuators in the second type actuator list information in a running state are determined as second target actuators.

[0069] It can be understood that after obtaining the complete first type actuator list information and the second type actuator list information, all actuators in the first type actuator list in a running state can be screened and determined as first target actuators. The determination of the running state is a comprehensive judgment process based on multi-dimensional parameters, which can include not only the online state and signal of the actuator, but also the historical failure rate of the device, the current throttling capacity, the valve body wear judgment data, the internal actuator feedback signal of the actuator, the control instruction response delay and whether the current steam demand exceeds its capacity limit. The same running state screening is performed on the second type actuator. Since the second type actuator is mainly used for steady-state control of the second section, its operating characteristics are more biased towards smooth adjustment and continuous supply, so the judgment logic of the running state is different from that of the first type actuator.

[0070] S333, adjusting the process parameters of the first target actuator and the second target actuator according to the target control scheme.

[0071] It can be understood that the process parameters mainly include the actuator valve position, pressure target, flow setting, opening speed, adjustment step, response time threshold, and stable pressure window range, which are key variables reflecting the steam control behavior. Since the regulation of the two sections has a coupling relationship, the parameter adjustment must follow a coordination mechanism: a cross-section collaborative control model can be established in advance, and using real-time pressure-flow coupling curve, section steam demand curve, valve dynamic response model and other data, the steam distribution equilibrium point of the two sections under the target working condition is calculated. Then according to this equilibrium point, the adjustment task that each target actuator should undertake is deduced reversely, for example, the first section may need to speed up the response speed to suppress the pressure mutation, and the second section needs to expand the stable pressure range to adapt to the new dynamic load.

[0072] In a possible implementation, the method further includes: S334, when there is at least one first type actuator in a runnable state and all second type actuators are not in a runnable state, generating a first temporary regulation parameter according to the target control scheme; the first temporary regulation parameter is used to adjust the working mode of the first type actuator to make up for the functional vacancy of the second type actuator.

[0073] It can be understood that when at least one of the first type actuators is in a runnable state and all of the second type actuators are not runnable, a first temporary regulation parameter can be generated to make up for the functional vacancy of the second type actuator. In actual industrial operation, the actuators of the second section may be completely unavailable due to maintenance, failure or safety locking, which will cause the second protection strategy to fail to execute normally. To avoid the risk of overpressure, temperature out of control, product quality fluctuation and other risks caused by the loss of protection function of the second section, a set of substitute mechanism can be constructed in advance, that is, the first type actuator is allowed to undertake part or all of the functions of the second type actuator. Since the device logic and control target of the two sections are different, the first temporary regulation parameter is not simply a copy of the parameters of the second protection strategy, but is recalculated through the cross-section steam transmission model and the device capability model. For example, it can be calculated whether the adjustable margin, the maximum continuous output capacity and the dynamic response time of the first section actuator after undertaking additional load can meet the requirements of the second protection strategy. If it can meet, a set of new temporary regulation parameters are generated, including a new valve position adjustment range, a more stringent pressure quantification limit, and a more gentle adjustment curve, to ensure that the first section actuator can complete its own section protection and also consider the stability requirements of the second section.

[0074] S335, adjusting the process parameters of the first type actuator according to the target control scheme based on the first temporary regulation parameter.

[0075] It can be understood that after the first temporary control parameter is generated, the process parameters of the first type of actuator can be adjusted based on the parameter to maintain stability and safety when assuming a dual role. The core logic of this step is to convert the temporary control parameter into an actual executable command and write it into the parameter register of the actuator controller or the actuator mechanism. During execution, the system will reconfigure the response curve of the first type of actuator to balance the action rhythm of the first section fast adjustment requirement and the second section stable adjustment requirement. In addition, the system will enable an enhanced feedback mechanism at the actuator level, including increasing the sampling frequency, increasing the pressure fluctuation detection sensitivity, enabling the micro-step adjustment algorithm, etc., so that the actuator will not oscillate or overshoot when temporarily assuming the second type of function. The system will also predict the thermal response and pressure response of the actuator under different load changes through the process simulation module to ensure that the adjusted process parameters can cover the fluctuation range of the target working condition. This step makes the first type of actuator not only able to perform the safety action of the first section, but also able to stabilize the second section steam pressure in a temporary compensation manner, thereby ensuring that the entire system can still maintain a stable and safe operating state in the absence of actuators.

[0076] In a possible implementation, the method further includes: S336, when there is a second type of actuator in a runnable state and all first type actuators are not in a runnable state, then generating a second temporary control parameter according to the target control scheme; the second temporary control parameter is used to adjust the working mode of the second type of actuator to compensate for the functional vacancy of the first type of actuator.

[0077] It can be understood that when the control system detects that all first type actuators are in an unrunnable state, and the second type of actuator still maintains the runnable state, in order to avoid the fault of the overall control ability, the system must build a set of alternative temporary strategy to maintain the basic process control ability. The second temporary control parameter is not a simple copy of the original parameter of the second type of actuator in the target control scheme, but based on the overall constraint framework of the target control scheme, it carries out function mapping, ability compensation and running boundary recalibration on whether the second type of actuator can assume part of the functional vacancy of the first type of actuator. Therefore, the essence of the second temporary control parameter is a function compensation type parameter set, which maps the process variable control (such as basic stability maintenance, primary driving variable management, key safety threshold maintenance, etc.) originally responsible for the first type of actuator to the adjustment space of the second type of actuator according to the feasible proportion, to ensure that the overall process does not drift without control.

[0078] In a specific implementation, the unoperable state of the first type of actuator can be confirmed as persistent rather than transient fluctuation based on real-time feedback from the actuator state monitoring module, and then the definition of the overall control target, variable constraint interval, working condition stability requirement, and reaction stage model in the target control scheme is called. Subsequently, an actuator capacity substitution matrix can be constructed for analyzing the coverability of the second type of actuator to the variable responsible for the first type of actuator. Based on the substitution matrix, a temporary control optimization model is constructed, and by introducing variable substitution factors, response delay compensation factors, and resource load factors, the process parameters of the first type of actuator after failure are projected to the second type of actuator. For example, for some variables, the following equation is constructed wherein is the first type of actuator variable required by the target scheme, is the substitutable proportion, reflects the compensation ability of the second type of actuator, is the temporary compensation amount. The second temporary control parameter formed finally not only contains the newly set target value, but also contains the actuator action mode, response speed adjustment factor, and stability constraint for preventing overcompensation.

[0079] S337, based on the second temporary control parameter, adjusting the process parameters of the second type of actuator according to the target control scheme.

[0080] It can be understood that the generated second temporary control parameter can be formally applied to the second type of actuator, so that the process parameters are completely reconstructed at the running level to meet the current stage requirements of the target control scheme. The temporary control parameter can be converted into a parameter instruction recognizable by the actuator bottom layer, and the internal drive model, feedback sampling period, dynamic response characteristics, and boundary conditions of the actuator are reconfigured, so that the second type of actuator can still maintain stability and predictability under the condition of bearing additional control tasks.

[0081] Exemplarily, the target variable, compensation factor, response constraint, and running mode switching instruction in the second temporary control parameter can be read, and then mapped to the specific adjustable parameters of the second type of actuator through the process parameter distribution module. For example, for flow regulating type actuators, it may be necessary to adjust the valve opening curve, PID parameter, hysteresis compensation coefficient, or even the maximum action frequency of the actuator; since the second type of actuator assumes part of the responsibility of the first type of actuator, its parameter adjustment formula usually contains a constraint superposition mechanism, for example: wherein is the control signal of the original second type of actuator in the target control scheme, is the compensation instruction introduced by the temporary control parameter, The compensation weight is dynamically calculated by the system according to the current working condition. Such a structure can ensure that the performance control task is inherited while enhancing the control ability of the process stability variable. The process parameters of the second type executor change from the original cooperative regulation mode to the main regulation mode, which means that the role has changed essentially. To ensure that this role change can be completed smoothly without damaging the process continuity, the second type executor will operate according to the synthesis rule of the target control scheme and the temporary compensation strategy, thereby effectively compensating for the functional defects of the first type executor and keeping the entire system controllable, stable and continuously evolving towards the target working condition.
