Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy-saving control, and more particularly to an energy-saving control system and method for a paper roll processing device. BACKGROUND

[0002] Energy-saving control is one of the core technologies for paper roll processing devices to achieve green production and cost optimization. It aims to monitor the load working conditions, energy consumption data and running state of each process link of the device in real time, optimize energy consumption related parameters such as motor speed, heating temperature and tension in combination with processing quality requirements, reduce invalid energy consumption and excessive regulation loss, and at the same time ensure that the paper roll flatness, moisture content and other processing indicators meet the standards. Energy-saving control is widely used in large-scale paper roll processing production lines. By improving the accuracy of energy consumption regulation and the adaptability of working conditions, the energy consumption per unit of production is reduced, which meets the green transformation needs of the manufacturing industry. It is an important means for the paper roll processing industry to achieve energy efficiency upgrading and sustainable development.

[0003] However, the existing energy-saving control of paper roll processing devices does not systematically retrieve load working condition information and device state data for energy efficiency characteristic verification, lacks the mining of the flexible fitting properties of device energy efficiency regulation, and does not monitor the working condition energy efficiency of different process links in real time to determine the response energy efficiency demand of process linkage. At the same time, it does not determine the energy consumption stratification strategy of each running state to determine the energy efficiency regulation and stabilization period and the behavior consumption average constraint, so that the device energy efficiency regulation lacks precise adaptive boundaries and dynamic situation basis, leading to the regulation process easily exceeding the device energy efficiency stabilization interval or deviating from the processing quality demand, so that the energy efficiency quality and energy-saving stability of the whole process of paper roll processing cannot meet the production scene demand of multi-specification processing and multi-working condition switching. Therefore, how to accurately and dynamically regulate the energy efficiency quality of the device under the dynamic working condition of the whole process of paper roll processing to improve the energy efficiency adaptability of the paper roll processing device is a problem faced by the industry. SUMMARY

[0004] The present application provides an energy-saving control system and method for a paper roll processing device, which can accurately and dynamically regulate the energy efficiency quality of the device under the dynamic working condition of the whole process of paper roll processing to improve the energy efficiency adaptability of the paper roll processing device.

[0005] In a first aspect, the present application provides an energy-saving control method for a paper roll processing device, which comprises the following steps: Retrieving load working condition information and device state data during the running process of the paper roll processing device, verifying the energy efficiency characteristics of the load working condition information and the device state data, and obtaining the flexible fitting properties of the paper roll processing device during energy efficiency regulation; During the paper roll processing, the energy efficiency of the paper roll processing equipment at different process stages is monitored in real time to obtain the response energy efficiency requirements of the paper roll processing equipment when the process is linked. Then, the energy efficiency status of the paper roll processing process is determined by the response energy efficiency requirements and the current operating mode of the paper roll processing equipment. The energy consumption stratification strategy of the paper roll processing equipment under various operating states is collaboratively determined to obtain the energy efficiency adjustment and stabilization cycle corresponding to the energy-saving adjustment rule under each operating state. The behavioral consumption average constraint during energy efficiency adaptation in the paper roll processing process is determined by all energy efficiency adjustment and stabilization cycles and the flexible fitting attribute. Based on the energy efficiency situation and the behavioral consumption constraints, dynamic energy-saving control is carried out on the energy efficiency quality of the entire paper roll processing process.

[0006] In this embodiment, the load condition information refers to real-time data on the energy demand intensity during the paper roll processing equipment's processing.

[0007] In this embodiment, the energy efficiency characteristics of the load condition information and the equipment status data are verified to obtain the flexible fit attributes of the paper roll processing equipment in energy efficiency regulation, specifically including: The energy efficiency characteristic verification indicators are determined based on the load condition information and the equipment status data. The energy efficiency matching gradient of the paper roll processing equipment during energy efficiency control is constructed using the energy efficiency characteristic verification indicators. The flexible matching attribute of the paper roll processing equipment in energy efficiency regulation is determined by the energy efficiency matching gradient.

[0008] In this embodiment, the flexible fit attribute refers to the ability of the paper roll processing equipment to stably achieve a high-efficiency adaptation range under different working conditions and the responsiveness of adjusting the equipment's energy efficiency to the optimal value when switching working conditions.

[0009] In this embodiment, the energy efficiency of different process stages of the paper roll processing equipment is monitored in real time to obtain the specific energy efficiency requirements of the paper roll processing equipment during process linkage, including: Based on the energy efficiency of different process stages of paper roll processing equipment, the energy efficiency response characteristics of linkage during process linkage are constructed. Based on the energy efficiency response characteristics, determine the energy efficiency linkage mode of the paper roll processing equipment during process linkage; Extract the response energy efficiency requirements of the paper roll processing equipment during process linkage from the energy efficiency linkage mode.

[0010] In this embodiment, the operating condition energy efficiency refers to the energy utilization efficiency of the paper roll processing equipment under specific operating conditions.

[0011] In this embodiment, the energy conversion efficiency status refers to the comprehensive judgment result of the overall level, changing trend and key disturbance effects of the equipment's energy conversion efficiency during the paper roll processing.

[0012] In this embodiment, the energy consumption stratification strategy for the paper roll processing equipment under various operating states is collaboratively determined, and the energy efficiency adjustment and stabilization cycle corresponding to the energy-saving setting rule under each operating state is specifically included as follows: Strategies for energy consumption stratification of paper roll processing equipment under various operating conditions; Based on each energy consumption stratification strategy, determine the collaborative judgment features corresponding to the energy-saving tuning rules under each operating state; Determine the energy efficiency over-limit sequence corresponding to the energy-saving tuning rule based on all collaborative judgment features; The energy efficiency adjustment and stabilization cycle corresponding to the energy-saving setting rule under each operating state is extracted from the energy efficiency over-limit sequence.

[0013] In this embodiment, the energy consumption stratification strategy refers to a set of energy-saving operation rules with hierarchical differences formulated based on different operating states of the paper roll processing equipment.

[0014] Secondly, this application provides an energy-saving control system for paper roll processing equipment, used to execute an energy-saving control method for paper roll processing equipment, the energy-saving control system comprising: The energy efficiency verification module is used to retrieve load condition information and equipment status data during the operation of the paper roll processing equipment, verify the energy efficiency characteristics of the load condition information and the equipment status data, and obtain the flexible fit attribute of the paper roll processing equipment in energy efficiency regulation. The demand monitoring module is used to monitor the energy efficiency of different process links of the paper roll processing equipment in real time during the paper roll processing process, obtain the response energy efficiency requirements of the paper roll processing equipment when the process is linked, and then determine the energy efficiency status of the paper roll processing process based on the response energy efficiency requirements and the current operating mode of the paper roll processing equipment. The collaborative determination module is used to collaboratively determine the energy consumption stratification strategy of the paper roll processing equipment under various operating states, obtain the energy efficiency adjustment and stabilization cycle corresponding to the energy-saving adjustment rule under each operating state, and determine the behavioral consumption average constraint when energy efficiency is adapted during the paper roll processing process by using all energy efficiency adjustment and stabilization cycles and the flexible fitting attribute. The energy-saving control module is used to dynamically control the energy efficiency and quality of the entire paper roll processing process based on the energy conversion efficiency status and the behavioral consumption constraints.

[0015] The technical solutions provided by the embodiments disclosed in this application have the following beneficial effects: Load condition information and equipment status data during the operation of the paper roll processing equipment are retrieved. The load condition information and equipment status data are then used to verify energy efficiency characteristics, obtaining the flexible fit attributes of the paper roll processing equipment during energy efficiency control. During paper roll processing, the energy efficiency of different process stages of the paper roll processing equipment is monitored in real time to obtain the response energy efficiency requirements of the paper roll processing equipment during process linkage. The energy conversion efficiency status during paper roll processing is then determined based on the response energy efficiency requirements and the current operating mode of the paper roll processing equipment. The energy consumption stratification strategy of the paper roll processing equipment under each operating state is collaboratively determined to obtain the energy efficiency stabilization cycle corresponding to the energy-saving tuning rule for each operating state. The behavioral energy consumption average constraint during energy efficiency adaptation during paper roll processing is determined through all energy efficiency stabilization cycles and the flexible fit attributes. Based on the energy conversion efficiency status and the behavioral energy consumption average constraint, dynamic energy-saving control is performed on the energy efficiency quality of the entire paper roll processing process.

[0016] Therefore, this application demonstrates that, even under the premise of existing paper roll processing equipment energy-saving control systems lacking systematic data retrieval and energy efficiency adaptation boundaries, it lays a precise data and characteristic foundation for energy efficiency regulation. Specifically, by retrieving load condition information and equipment status data during the operation of the paper roll processing equipment and verifying energy efficiency characteristics to obtain flexible fit attributes, it solves the problems of data fragmentation and lack of clear energy efficiency adaptation range in traditional control, clearly defining the load-state interval and operating condition switching response capability for high-efficiency equipment operation. Furthermore, by real-time monitoring of the energy efficiency of different process stages during paper roll processing, it obtains responsive energy efficiency requirements and determines the energy efficiency status, breaking the isolation of single-stage energy efficiency monitoring in traditional control, solving the problems of energy efficiency analysis bias and lack of dynamic status basis during stage linkage, and intuitively presenting each stage. By analyzing the energy efficiency variation patterns and overall energy conversion trends of coordinated operation, the adaptability of energy efficiency control to process linkage is improved. By coordinating the energy consumption stratification strategy for each operating state of the paper roll processing equipment, the energy efficiency stabilization cycle is obtained and the behavioral consumption average constraint is determined. This solves the problems of lack of coordination in energy consumption strategies and lack of clear parameter fluctuation boundaries in traditional control, standardizes the adaptability of energy-saving rules under different states, and clarifies the energy efficiency stabilization time and the fluctuation range of core parameters. By dynamically controlling the energy efficiency quality of the entire paper roll processing process, the problems of disconnect between traditional fixed parameter control and actual working conditions and poor energy efficiency quality can be solved. A closed-loop mechanism of "analysis-control-feedback" is formed, which optimizes energy efficiency in real time while ensuring processing quality, balances energy consumption and operational stability in each link, and significantly improves the energy efficiency adaptability and energy-saving efficiency of the entire paper roll processing process.

[0017] In summary, the technical solution adopted in this application can accurately and dynamically regulate the energy efficiency and quality of the equipment under dynamic working conditions throughout the entire paper roll processing process, thereby improving the energy efficiency adaptability of the paper roll processing equipment.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] This application provides an energy-saving control system and method for paper roll processing equipment. The core of this system involves retrieving load condition information and equipment status data during the operation of the paper roll processing equipment, verifying the energy efficiency characteristics of the load condition information and equipment status data to obtain the flexible fit attributes of the paper roll processing equipment during energy efficiency regulation. During paper roll processing, the system monitors the energy efficiency of different process stages of the paper roll processing equipment in real time to obtain the response energy efficiency requirements of the paper roll processing equipment during process linkage. Then, the system determines the energy conversion efficiency status during the paper roll processing process based on the response energy efficiency requirements and the current operating mode of the paper roll processing equipment. The system collaboratively determines the energy consumption stratification strategy of the paper roll processing equipment under each operating state to obtain the energy efficiency stabilization cycle corresponding to the energy-saving tuning rule for each operating state. The system determines the behavioral energy consumption average constraint for energy efficiency adaptation during the paper roll processing process based on all energy efficiency stabilization cycles and the flexible fit attributes. Finally, the system dynamically regulates the energy efficiency quality of the entire paper roll processing process based on the energy conversion efficiency status and the behavioral energy consumption average constraint.

[0022] Example 1: To better understand the above technical solution, the following will provide a detailed description of the technical solution in conjunction with the accompanying drawings and specific implementation methods. (Refer to...)Figure 1 As shown in the figure, this is an exemplary flowchart of an energy-saving control method for a paper roll processing equipment according to this embodiment of the present application. The energy-saving control method includes the following steps: In step S1, load condition information and equipment status data during the operation of the paper roll processing equipment are retrieved, and the energy efficiency characteristics of the load condition information and equipment status data are verified to obtain the flexible fit attribute of the paper roll processing equipment in energy efficiency regulation.

[0023] In practice, retrieving load condition information and equipment status data during the operation of paper roll processing equipment can be achieved in the following way: First, deploy dedicated sensing and metering equipment in the key functional areas of the paper roll processing equipment: install torque sensors in the winding and unwinding mechanisms to collect the output torque of the main shaft, install pressure sensors in the cutting mechanism to obtain the cutting pressure, and install power sensors at the drive motor to record real-time power; simultaneously, install temperature sensors in the heating module, transmission system oil temperature box, and bearing housing, install speed sensors at the motor shaft end, and install smart meters in the main power distribution box and on the separate circuits of the motor, heating, and hydraulic subsystems. All sensors and meters can be connected to the edge computing gateway via the Profinet industrial bus. After receiving the data in real time, the gateway performs deduplication and filtering to remove outliers, and then encapsulates it in the format of "equipment number - acquisition time - data type". By reading the encapsulated data, the load condition information and equipment status data during the operation of the paper roll processing equipment can be obtained, which will not be elaborated here.

[0024] It should be noted that, in this application, load condition information refers to real-time data on the energy demand intensity during the paper roll processing equipment's processing; equipment status data refers to real-time data on the paper roll processing equipment's own operational health and energy consumption baseline.

[0025] In this embodiment, the energy efficiency characteristics of the load condition information and the equipment status data are verified, and the flexible fit attribute of the paper roll processing equipment in energy efficiency regulation can be obtained by the following steps: The energy efficiency characteristic verification indicators are determined based on the load condition information and the equipment status data. The energy efficiency matching gradient of the paper roll processing equipment during energy efficiency control is constructed using the energy efficiency characteristic verification indicators. The flexible matching attribute of the paper roll processing equipment in energy efficiency regulation is determined by the energy efficiency matching gradient.

[0026] In practice, the process begins by extracting motor output power, winding tension, paper roll thickness, and processing length per unit time from load condition information. Then, it extracts motor speed, real-time heating module temperature, transmission system oil temperature, and power consumption of each subsystem (motor, heating, hydraulic) from equipment status data. Next, considering paper roll processing quality requirements (such as paper roll flatness and moisture content), parameters directly related to energy efficiency are selected as candidate indicators. Referring to the rated parameters in the equipment manufacturer's manual (such as motor rated power and heating module rated temperature) and industry energy efficiency standards, the acceptable range for each candidate indicator is determined. For example, the acceptable range for motor output power is 60%–90% of the rated power, and the acceptable range for heating module temperature is 65℃–75℃. This ultimately forms a set of energy efficiency characteristic verification indicators that includes "motor output power compliance rate, power consumption per unit processing length, and heating module energy consumption-moisture content matching degree." Then, the load levels were divided according to the intensity differences of the load conditions, with "motor output power + paper roll thickness" as the core dividing criteria. The load was divided into three levels: low load (motor output power 60%–70%, paper roll thickness 0.1–0.15 mm), medium load (motor output power 70%–80%, paper roll thickness 0.15–0.25 mm), and high load (motor output power 80%–90%, paper roll thickness 0.25–0.3 mm). For each level, energy efficiency characteristic verification index data were collected for 24 consecutive hours, such as the hourly power consumption per unit processing length and the motor output power compliance rate under the low load level. The least squares method was used to fit the "load parameter – energy efficiency index" data for each level, obtaining a linear curve of energy efficiency index changing with load within each level. The curves were then arranged in order of level to form an energy efficiency matching gradient from low load to high load, i.e., the energy efficiency matching gradient of the paper roll processing equipment during energy efficiency control. Finally, the energy efficiency compliance rate of each level in the energy efficiency matching gradient is statistically analyzed (energy efficiency compliance rate = duration within the energy efficiency index compliance range of that level / total duration). Levels with a compliance rate ≥ 90% are selected. The load and equipment status parameter ranges of these levels are integrated to form the "fit range" in which the equipment can stably achieve high efficiency. For example, the integrated fit range is a motor speed of 800-1200 rpm and a paper roll thickness of 0.1-0.25 mm. The switching process between different compliance levels is then tested: switching from a low load level to a medium load level, the time it takes for the equipment to adjust from the current energy efficiency value to the optimal energy efficiency value of the medium load level is recorded. The test is repeated 5 times and the average value is taken. If the average adjustment time is ≤ 30 seconds and the energy efficiency fluctuation during the adjustment is ≤ 10%, the "response flexibility" of the equipment is determined. The fit range and response flexibility are then combined to form the flexible matching attribute of the paper roll processing equipment in energy efficiency control.

[0027] It should be noted that, in this application, the energy efficiency characteristic verification index refers to the specific set of parameters that measure the degree of matching between the energy efficiency performance of the paper roll processing equipment and the load conditions and equipment operating status; the energy efficiency matching gradient refers to the hierarchical structure divided according to the load conditions of the paper roll processing equipment, with each level corresponding to a specific equipment status and energy efficiency index range; the flexible matching attribute refers to the adaptability range of the paper roll processing equipment to achieve high efficiency under different operating conditions and the responsiveness of the equipment to adjust its energy efficiency to the optimal value when switching operating conditions.

[0028] In step S2, during the paper roll processing, the energy efficiency of the paper roll processing equipment at different process stages is monitored in real time to obtain the response energy efficiency requirements of the paper roll processing equipment during process linkage. Then, the energy efficiency status of the paper roll processing process is determined by the response energy efficiency requirements and the current operating mode of the paper roll processing equipment.

[0029] In this embodiment, the energy efficiency of the paper roll processing equipment at different process stages is monitored in real time during the paper roll processing process. The response energy efficiency requirements of the paper roll processing equipment during process linkage can be achieved through the following steps: Based on the energy efficiency of different process stages of paper roll processing equipment, the energy efficiency response characteristics of linkage during process linkage are constructed. Based on the energy efficiency response characteristics, determine the energy efficiency linkage mode of the paper roll processing equipment during process linkage; Extract the response energy efficiency requirements of the paper roll processing equipment during process linkage from the energy efficiency linkage mode.

[0030] In practical implementation, firstly, for the core processes of paper roll processing, including unwinding, cutting, drying, and winding, select core operating condition energy efficiency indicators for each process: "Power consumption per unit unwinding length" for unwinding, "Ratio of energy consumption per single cut to cutting frequency" for cutting, "Heating energy consumption per unit time and rate of change in paper roll moisture content" for drying, and "Energy consumption of winding motor and rate of increase in winding diameter" for winding. Corresponding sensors are installed at each process, such as smart meters and length counters at the unwinding point, and energy consumption monitors and moisture content detectors at the drying point, to collect energy efficiency data every 10 seconds in real time. The data from each process are correlated over time; for example, the energy efficiency data changes of the cutting, drying, and winding processes are recorded after the unwinding speed increases from 80m / min to 100m / min. These correlated data are then integrated to form a process-linked energy efficiency response characteristic. Then, the constructed energy efficiency response characteristic data were categorized according to processing task specifications into three scenarios: thin paper rolls (thickness 0.1–0.15 mm), medium-thick paper rolls (0.15–0.25 mm), and thick paper rolls (0.25–0.3 mm). The characteristic data for each scenario were processed using the K-means clustering algorithm, with a cluster size of 3. Similar features were grouped into one category by calculating the Euclidean distance between data points. Each clustering result corresponds to a set of energy efficiency data combinations. For example, in the thin paper roll scenario, "low energy consumption for unwinding + low energy consumption for low-frequency cutting + low energy consumption for low-temperature drying" constitutes one category. After verification through 20 consecutive batches of processing, clusters with a processing pass rate ≥99% were selected. These categories were used as the energy efficiency linkage modes for the paper roll processing equipment during process linkage. Finally, for each energy efficiency linkage mode, the energy efficiency index range of each process step was analyzed. Taking the "thin paper roll processing energy efficiency linkage mode" as an example, the energy consumption data of the drying stage under this mode is statistically analyzed to find the lowest energy consumption value (e.g., 3.2 kWh per hour) that can stabilize the moisture content of the paper roll at 8% to 10%. The unwinding stage is analyzed to determine the highest power consumption per unit length (e.g., 0.015 kWh per meter) that ensures stable paper roll tension without breakage. According to the order of unwinding, cutting, drying, and winding, the "minimum energy efficiency guarantee value" or "maximum energy efficiency limit value" of each stage under the corresponding mode is compiled. These values ​​are collected as the response energy efficiency requirements of the paper roll processing equipment when the process is linked.

[0031] It should be noted that, in this application, operating condition energy efficiency refers to the energy utilization efficiency of paper roll processing equipment under specific operating conditions; process linkage refers to the coordinated operation and mutual adaptation of various process links in paper roll processing; energy efficiency response characteristics refer to the dynamic set of energy efficiency indicators changing with operating conditions when various process links in paper roll processing are linked; energy efficiency linkage mode refers to the typical form of coordinated change of energy efficiency indicators of different process links in paper roll processing under specific processing task specifications; and response energy efficiency demand refers to the energy efficiency indicator thresholds that each link must meet to ensure processing quality and efficiency when various process links in paper roll processing are linked.

[0032] Preferably, in this embodiment, the energy efficiency situation during the paper roll processing process is determined by the response energy efficiency requirement and the current operating mode of the paper roll processing equipment, with reference to... Figure 2 As shown in the figure, this is a flowchart illustrating the process of determining the energy conversion utility situation in some embodiments of this application. In this embodiment, determining the energy conversion utility situation can be achieved through the following steps: In step S21, the limiting adaptation degree between the energy efficiency requirement and the operating mode is determined based on the response energy efficiency requirement and the current operating mode. In step S22, the delamination disturbance properties during the paper roll processing are determined based on the width limiting adaptation degree; In step S23, the utility status description corresponding to the current operating mode of the paper roll processing equipment is determined; In step S24, the energy conversion utility state during the paper roll processing is determined based on the layered perturbation attributes and the utility state description.

[0033] In practice, the process begins by breaking down the indicators for each stage of the energy efficiency requirement, such as "power consumption per unit length ≤ 0.015 kWh" for the unwinding stage and "energy consumption per hour ≤ 3.2 kWh" for the drying stage. Then, parameters for the current operating mode are extracted. If the current mode is thin paper roll processing, real-time energy consumption data for stages such as unwinding and drying are recorded. A "single-stage adaptability calculation + overall averaging" method is used. The formula for single-stage adaptability is (1 - |current stage real-time energy efficiency value - response energy efficiency requirement value| / response energy efficiency requirement value) × 100%. For example, if the real-time energy consumption for the drying stage is 3.0 kWh, the adaptability is (1 - |3.0 - 3.2| / 3.2) × 100% ≈ 93.75%. After calculating the adaptability of all stages, the average value is taken. This average value represents the limit adaptability between the energy efficiency requirement and the operating mode. Next, the disturbance level ranges for the width-fitting degree are defined: ≥90% is low disturbance (operation meets requirements), 70%–89% is medium disturbance (slight deviation from requirements), and <70% is high disturbance (severe deviation from requirements). Then, corresponding to each process step in paper roll processing—unwinding, cutting, drying, and winding—the single-step fit of each step is assigned to the corresponding disturbance level, such as unwinding fit of 92% (low disturbance), cutting fit of 80% (medium disturbance), and winding fit of 65% (high disturbance). This is organized into a table based on the correspondence between "process step – disturbance level," which represents the layered disturbance attributes in the paper roll processing process. Then, energy efficiency data is collected for two consecutive hours under the current operating mode, including energy consumption per unit output at each step, the percentage of time the energy efficiency meets the standard, and the amplitude of energy consumption fluctuations. Three descriptive dimensions are set: "energy efficiency stability," "energy consumption trend," and "compliance rate." If energy consumption fluctuation is ≤5%, then "energy efficiency stability is good"; if energy consumption shows a continuous downward trend over the past 30 minutes, then "energy consumption trend is positive"; if the energy efficiency compliance time accounts for ≥95%, then "energy efficiency compliance rate is high." The results of these three dimensions are integrated to form a conclusion such as "Under the current paper roll processing mode, the equipment has good energy efficiency stability, a positive energy consumption trend, and a high compliance rate." This conclusion serves as the utility status description corresponding to the current operating mode of the paper roll processing equipment. Finally, the impact of high-disturbance links in the layered disturbance attributes is analyzed. For example, if the winding link is a high-disturbance link, it needs to be explained that it may lead to "a decrease in the energy conversion efficiency of the winding motor." This is then combined with the qualitative conclusions in the utility status description, such as "good energy efficiency stability and a positive trend." Combining the two, we first give an overall assessment, and then supplement the impact of disturbances to form the energy conversion efficiency situation in the paper roll processing process: "The energy conversion efficiency situation in the current paper roll processing process is generally optimized, the energy conversion efficiency of the equipment meets expectations and is on an upward trend, but the high disturbance in the winding stage may affect the stability of subsequent energy conversion."

[0034] It should be noted that, in this application, the current operating mode refers to the combination of operating parameters and working methods currently used by the paper roll processing equipment; the limit adaptation degree refers to a quantitative indicator that measures the degree of matching between the actual energy efficiency of the paper roll processing equipment under the current operating mode and the energy efficiency requirements of the process linkage; the hierarchical disturbance attribute refers to the distribution of the degree of disturbance caused by the deviation of energy efficiency from the response requirements in different links according to each process link of paper roll processing; the utility status description refers to the qualitative results of the energy efficiency stability, energy consumption change trend and energy efficiency compliance status under the current operating mode of the paper roll processing equipment; and the energy conversion utility status refers to the comprehensive judgment result of the overall level, change trend and key disturbance impact of the equipment's energy conversion efficiency during the paper roll processing process.

[0035] In step S3, the energy consumption stratification strategy of the paper roll processing equipment under each operating state is collaboratively determined to obtain the energy efficiency adjustment cycle corresponding to the energy saving setting rule under each operating state. The behavioral consumption average constraint during energy efficiency adaptation in the paper roll processing process is determined by all energy efficiency adjustment cycles and the flexible fitting attribute.

[0036] In this embodiment, the energy consumption stratification strategy for the paper roll processing equipment under various operating states is collaboratively determined, and the energy efficiency adjustment and stabilization cycle corresponding to the energy-saving setting rule for each operating state can be obtained by the following steps: Strategies for energy consumption stratification of paper roll processing equipment under various operating conditions; Based on each energy consumption stratification strategy, determine the collaborative judgment features corresponding to the energy-saving tuning rules under each operating state; Determine the energy efficiency over-limit sequence corresponding to the energy-saving tuning rule based on all collaborative judgment features; The energy efficiency adjustment and stabilization cycle corresponding to the energy-saving setting rule under each operating state is extracted from the energy efficiency over-limit sequence.

[0037] In practice, the first step is to define the core operating states of the paper roll processing equipment, which are divided into startup, stable processing, and mode switching states. By consulting the parameter configuration documentation of the equipment control system, energy consumption stratification strategies for each state are extracted: the startup state strategy is "step-by-step motor speed increase (100 rpm every 10 seconds) + segmented preheating of the heating module (50℃→60℃→70℃)"; the stable processing state strategy is "adjusting winding tension according to paper roll thickness (10% for thick paper, -8% for thin paper) + dynamic matching of drying temperature with moisture content (2℃ increase when moisture content > 10%)"; and the mode switching state strategy is "motor deceleration time ≥ 20 seconds + heating module insulation temperature ± 1℃". Simultaneously, strategies validated in historical production records are used to supplement and refine these strategies, forming energy consumption stratification strategies for each operating state of the paper roll processing equipment. Next, the energy consumption stratification strategy for each operating state is broken down into its energy-saving tuning rules, such as the "step-by-step motor speed increase" rule and the "segmented preheating" rule for the startup state. For each rule, collaborative judgment features are extracted: taking the "motor stepped speed-up" rule as an example, the features include "speed-up rate (100 rpm / 10 seconds)," "interval between adjacent speed-up stages (10 seconds)," and "maximum limit of motor current fluctuation during speed-up (120% of rated current)." Taking the "segmented preheating" rule as an example, the features include "temperature thresholds for each preheating stage (50℃, 60℃, 70℃)," "duration of each stage (5 minutes each)," and "synchronization with motor speed-up (motor speed-up starts 30 seconds after preheating begins)." These features are organized according to the structure of "operating state - energy-saving setting rule - feature parameters" to form the collaborative judgment features corresponding to the energy-saving setting rule for each operating state. Then, a qualified range is set for each collaborative judgment feature, such as the qualified range for "motor speed-up rate" being 80-120 rpm / 10 seconds and the qualified range for "interval between heating and preheating stages" being 4-6 minutes. When the equipment executes the energy consumption stratification strategy for each operating state, the actual data of the collaborative judgment features is collected in real time by sensors and recorded every 5 seconds. Compare the actual data with the acceptable range. If a certain characteristic data exceeds the range (e.g., acceleration rate is only 70 rpm / 10 seconds), record that moment as the over-limit time point and indicate the degree of over-limit (e.g., below the lower acceptable limit by 12.5%). Organize all over-limit time points and their corresponding degrees into an ordered list in chronological order. This list serves as the energy efficiency over-limit sequence corresponding to the energy efficiency tuning rule. Finally, for each over-limit time point in the energy efficiency over-limit sequence, trace the execution process of the corresponding energy efficiency tuning rule: find the over-limit start time (e.g., t1=10:05, acceleration rate first falls below the acceptable range), then determine the time it takes for the characteristic data to recover to the acceptable range using sensor data (e.g., t2=10:10, acceleration rate recovers to 90 rpm / 10 seconds), and calculate the difference between the two (t2-t1=5 seconds), which is the adjustment and stabilization time for a single over-limit.For all out-of-limit records of the same energy-saving setting rule, the single adjustment and stabilization time is calculated repeatedly, and then the arithmetic mean of all single adjustment and stabilization times is taken. This average value is the energy efficiency adjustment and stabilization cycle corresponding to the energy-saving setting rule for each operating state.

[0038] It should be noted that in this application, the energy consumption stratification strategy refers to a set of energy-saving operation rules with hierarchical differences formulated according to different operating states of the paper roll processing equipment; the energy-saving setting rules refer to the rules in the paper roll processing equipment used to standardize the setting of energy-saving parameters, ensure that energy consumption meets the standards, and adapt to various operating states; the collaborative judgment feature refers to a set of specific parameter dimensions for measuring the adaptability between different rules; the energy efficiency exceedance sequence refers to the orderly record of the time points and the degree of exceedance of the actual data of the collaborative judgment feature during the execution of the energy-saving setting rules; and the energy efficiency adjustment and stabilization cycle refers to the average time required for the collaborative judgment feature data to recover from the exceedance state to the qualified range after the execution of the energy-saving setting rules in a certain operating state of the paper roll processing equipment exceeds the limit.

[0039] Preferably, in this embodiment, the behavioral energy consumption constraint during energy efficiency adaptation in the paper roll processing is determined by all energy efficiency stabilization cycles and the flexible fit attribute, with reference to... Figure 3 As shown in the figure, this is a flowchart illustrating the process of determining the average behavior cost constraint in some embodiments of this application. In this embodiment, the determination of the average behavior cost constraint can be achieved by the following steps: In step S31, the dynamic adaptation decision for energy efficiency adaptation is determined based on all energy efficiency regulation cycles and the flexible fit attribute. In step S32, the energy consumption average delay rule for energy efficiency adaptation is determined based on the dynamic adaptation decision. In step S33, the elastic equilibrium boundary for energy efficiency adaptation during paper roll processing is determined by the energy consumption average delay rule. In step S34, the behavior consumption average constraint for energy efficiency adaptation during paper roll processing is determined based on the elastic equilibrium boundary.

[0040] In practice, the energy efficiency adjustment and stabilization cycle for all operating states is first summarized, such as 30 seconds for startup, 15 seconds for stable state, and 25 seconds for switching state. Then, the adaptation range (motor speed 800-1200 rpm, paper roll thickness 0.1-0.25 mm) and response flexibility (adjustment to optimal energy efficiency ≤ 30 seconds) are extracted from the flexible fit attributes. For each operating state, it is determined whether the energy efficiency adjustment and stabilization cycle matches the response flexibility: for stable state, if the adjustment is 15 seconds ≤ 30 seconds, the decision is "maintain the current adaptation parameters and prioritize energy efficiency stability"; for switching state, if the adjustment is 25 seconds close to 30 seconds, the decision is "pre-adjust startup parameters 0.5 seconds before switching conditions to shorten the adjustment and stabilization time". The decisions for all states are integrated to form information covering the entire operating scenario, and this information is used as the dynamic adaptation decision for energy efficiency adaptation. Next, for the adjustment requirements in dynamic adaptation decision-making, a quantitative standard for adjustment delay is set: for the stable state of "maintaining current parameters", the upper limit of the delay from detecting a small fluctuation in energy efficiency to executing the adjustment is specified as 1 second, to avoid frequent adjustments causing energy consumption fluctuations; for the switching state of "starting parameter pre-adjustment", the delay from recognizing the operating condition switching signal to starting pre-adjustment is specified as ≤0.3 seconds, to ensure matching with the energy efficiency regulation cycle (25 seconds) and avoid regulation timeout. At the same time, the starting point of the delay timing (such as the trigger time of the operating condition switching signal) and the timing method (real-time recording by a millisecond-level timer) are clearly defined, forming a complete energy consumption average delay rule for energy efficiency adaptation. Then, based on the delay time in the energy consumption average delay rule and combined with the adaptation range of the flexible fitting attribute, the allowable fluctuation range of each core parameter is calculated: for motor speed, within a delay of 0.3 seconds, the speed fluctuation shall not exceed 10% of the adaptation range (800-1200rpm), i.e., 720-1320rpm; for energy consumption, within a delay of 1 second, the energy consumption fluctuation of each subsystem shall be ≤15% (referring to the recovery capability within the energy efficiency regulation cycle). Meanwhile, for the heating module temperature, a temperature fluctuation of ±2℃ is specified during the delay period (to ensure stable paper roll moisture content). These parameter fluctuation ranges are compiled into a table of "Parameter Type - Allowable Fluctuation Range," which serves as the elastic equilibrium boundary for energy efficiency adaptation during paper roll processing. Finally, the parameter range of the elastic equilibrium boundary is integrated with the adjustment logic of dynamic adaptation decisions to form executable constraint rules: First, the motor speed must be maintained between 720-1320 rpm during equipment operation; exceeding this range triggers immediate adjustment. Second, the energy consumption fluctuation of each subsystem must not exceed 15%, and the adjustment delay must be ≤1 second. Third, during operating condition switching, the parameter pre-adjustment delay is ≤0.3 seconds, and the heating module temperature (fluctuation ±2℃) must be synchronously matched. A warning mechanism for violating constraints is also clearly defined (e.g., triggering an audible and visual alarm when exceeding the range). These rules are summarized to form the behavioral energy consumption average constraint for energy efficiency adaptation during paper roll processing.

[0041] It should be noted that, in this application, energy efficiency adaptation refers to the process of adjusting equipment operating elements to match energy efficiency requirements in paper roll processing, so that the operating state conforms to energy efficiency targets; dynamic adaptation decision refers to a dynamic scheme that guides energy efficiency adaptation adjustments in different operating states; consumption average delay rule refers to the rule that regulates the timing of energy efficiency adaptation adjustments, clarifying the maximum delay time and timing standard from triggering the adjustment signal to executing the adjustment; elastic equilibrium boundary refers to the maximum fluctuation range of the core operating parameters of the equipment within the allowable range of the consumption average delay rule; and behavioral consumption average constraint refers to the set of constraint rules that regulate the operating behavior and energy consumption fluctuations of paper roll processing equipment during the energy efficiency adaptation process.

[0042] In step S4, the energy efficiency quality of the entire paper roll processing process is dynamically controlled based on the energy conversion efficiency status and the behavioral energy consumption constraint.

[0043] In specific implementation, dynamic energy-saving control of the energy efficiency quality of the entire paper roll processing process based on the energy conversion efficiency trend and the behavioral energy consumption average constraint can be achieved in the following way: First, analyze the energy conversion efficiency trend of the paper roll processing process to identify the overall energy efficiency trend (such as optimization or deterioration) and high-disturbance links. For example, if the trend shows "overall optimization but high disturbance in the winding link", then the winding link is identified as the key control point. Then, compare with the parameter boundaries of the behavioral energy consumption average constraint, such as the motor speed needing to be between 720-1320 rpm and the energy consumption fluctuation range ≤15%. For stable processing conditions, if the energy consumption of the winding motor exceeds the upper limit of the constraint, reduce the winding motor speed by 5% within the constraint range and simultaneously reduce the winding tension by 3%, monitoring the adjusted energy consumption and speed data in real time through sensors; if the working condition changes (such as changing the paper roll specification), according to the requirement of "pre-adjustment delay ≤0.3 seconds" in the constraint, start the motor speed reduction and heating module heat preservation adjustment 0.3 seconds in advance to avoid parameters exceeding the limit. After adjustment, real-time data is fed back to the energy efficiency status analysis stage to determine whether the energy efficiency has returned to the optimization range. If it does not meet the standard, adjustments are repeated to form a closed loop of "analysis-adjustment-feedback" to ensure that the energy efficiency quality of the entire process meets the requirements. This will not be elaborated further here.

[0044] It should be noted that, in this application, energy efficiency quality refers to the overall performance of the equipment's energy efficiency stability, its adaptability to energy efficiency requirements, and its energy consumption balance throughout the entire paper roll processing process; dynamic energy-saving control refers to the control method of adjusting equipment parameters in real time to optimize energy efficiency and adapt to operating conditions based on real-time energy efficiency trends and behavioral consumption constraints.

[0045] Therefore, this application demonstrates that, even under the premise of existing paper roll processing equipment energy-saving control systems lacking systematic data retrieval and energy efficiency adaptation boundaries, it lays a precise data and characteristic foundation for energy efficiency regulation. Specifically, by retrieving load condition information and equipment status data during the operation of the paper roll processing equipment and verifying energy efficiency characteristics to obtain flexible fit attributes, it solves the problems of data fragmentation and lack of clear energy efficiency adaptation range in traditional control, clearly defining the load-state interval and operating condition switching response capability for high-efficiency equipment operation. Furthermore, by real-time monitoring of the energy efficiency of different process stages during paper roll processing, it obtains responsive energy efficiency requirements and determines the energy efficiency status, breaking the isolation of single-stage energy efficiency monitoring in traditional control, solving the problems of energy efficiency analysis bias and lack of dynamic status basis during stage linkage, and intuitively presenting each stage. By analyzing the energy efficiency variation patterns and overall energy conversion trends of coordinated operation, the adaptability of energy efficiency control to process linkage is improved. By coordinating the energy consumption stratification strategy for each operating state of the paper roll processing equipment, the energy efficiency stabilization cycle is obtained and the behavioral consumption average constraint is determined. This solves the problems of lack of coordination in energy consumption strategies and lack of clear parameter fluctuation boundaries in traditional control, standardizes the adaptability of energy-saving rules under different states, and clarifies the energy efficiency stabilization time and the fluctuation range of core parameters. By dynamically controlling the energy efficiency quality of the entire paper roll processing process, the problems of disconnect between traditional fixed parameter control and actual working conditions and poor energy efficiency quality can be solved. A closed-loop mechanism of "analysis-control-feedback" is formed, which optimizes energy efficiency in real time while ensuring processing quality, balances energy consumption and operational stability in each link, and significantly improves the energy efficiency adaptability and energy-saving efficiency of the entire paper roll processing process.

[0046] In summary, the technical solution adopted in this application can accurately and dynamically regulate the energy efficiency and quality of the equipment under dynamic working conditions throughout the entire paper roll processing process, thereby improving the energy efficiency adaptability of the paper roll processing equipment.
