Description

Technical Field

[0001] This invention relates to the field of intelligent machine control technology, specifically to an intelligent control method and system for a stenter. Background Technology

[0002] A finishing and setting machine is a key piece of equipment in the dyeing and printing industry, primarily used for finishing and setting fabrics. Its working principle is as follows: the fabric is immersed in a chemical mixture in a trough, then evenly pressed by rollers before entering an oven. Inside the oven, the fabric is dried and set under high-temperature hot air, causing changes in the fabric's molecular structure under the influence of heat and force, thereby achieving stable dimensions, shape, and a good hand feel. Therefore, to ensure effective fabric setting, good control of hot air temperature, good tension, and good conveying speed of the fabric entering the oven are crucial factors.

[0003] Currently, the control of setting machines typically involves: first, the setting machine generates a fixed tension, a fixed hot air temperature, and a fixed fabric conveying speed. For example, for setting polyester fabric, the conveying speed is initially controlled at approximately 25 meters per minute, the setting temperature at 180℃, and the tension at 15 cN / cm. Then, during the setting process, the setting effect is manually analyzed, and parameters are manually controlled based on the quality of the setting effect. For example, when the setting effect is poor, the fabric conveying speed is reduced, or the setting temperature or tension is increased. This manual control method relies heavily on the operator's experience in setting different types, sizes, and shapes of fabrics, lacks intelligence, and the setting effect is difficult to guarantee. Summary of the Invention

[0004] This invention aims to improve the intelligence level of dyeing and finishing machines in setting fabrics, reduce reliance on manual labor, and ensure the setting effect by providing an intelligent control method for finishing machines.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A method for intelligent control of a stenter machine is provided, comprising the following steps:

[0007] L1 determines the control conditions of the dyeing and finishing machine for the current time period, including finishing tension, finishing hot air temperature, and fabric conveying speed. Then, it collects and analyzes the fabric state data and finishing machine control deviation data generated within the conveying distance of the fabric in the current time period.

[0008] L2, based on the control deviation data of the setting machine, determines whether setting the fabric under the control conditions achieves the expected setting control effect.

[0009] If so, the fabric will continue to be shaped under the control conditions in the next consecutive time period following the current time period;

[0010] If not, the control conditions for the dyeing and setting machine in the next time period are determined according to a preset strategy.

[0011] Preferably, in step L1, the collected fabric state data includes: the resistance change collected by strain gauges placed at various points on the fabric at each data acquisition time in the current period.

[0012] The analyzed control deviation data of the setting machine includes: the absolute value of the difference between the tension at the corresponding point and the fabric tension applied to the fabric, calculated based on the fabric state data collected by the strain gauge at each point at each moment.

[0013] Preferably, the strain gauge tension at the corresponding points where the strain gauges are installed... It is calculated using the following formula:

[0014]

[0015] In formula (1), This represents the elastic modulus of the strain gauge;

[0016] This indicates the initial resistance of the strain gauge;

[0017] This indicates the change in resistance of the strain gauge;

[0018] This represents the sensitivity coefficient of the strain gauge.

[0019] Preferably, step L2, the method for determining whether the shaping of the fabric under the control conditions achieves the expected shaping control effect, specifically includes the following steps:

[0020] A1, calculate the average value of the absolute values ​​of the differences calculated at different data acquisition times for the same strain gauge;

[0021] A2, for each absolute value of the difference associated with the same strain gauge, determine whether the number of deviations from the average value associated with the strain gauge exceeds a preset threshold.

[0022] If so, the strain gauge is determined to be abnormal.

[0023] If so, the strain gauge is considered to be under normal strain.

[0024] A3, determine whether the ratio of the number of strain gauges with strain anomalies to the total number of strain gauges is greater than a preset first ratio threshold and less than a preset second ratio threshold.

[0025] If so, it is determined that the control conditions determined in step L1 have achieved the expected shaping control effect on the fabric.

[0026] If not, the control conditions for the dyeing and setting machine in the next time period are determined according to the preset strategy.

[0027] Preferably, in step A2, when the absolute value of the difference associated with the same strain gauge is less than or greater than the average value by more than a difference threshold, it is determined that the absolute value of the difference deviates from the average value.

[0028] Preferably, when the failure to achieve the expected setting control effect is of the type "the ratio is less than or equal to the first ratio threshold", in step L2, the control conditions for the dyeing and finishing machine in the next time period are determined according to the first preset strategy. The specific method includes the following steps:

[0029] B1, determine whether the ratio is greater than a third ratio threshold and less than or equal to the first ratio threshold.

[0030] If so, proceed to step B2;

[0031] If not, then prompt for manual intervention to set the control conditions for the next time period;

[0032] B2, calculate the level of the first ratio threshold interval between the first ratio threshold and the third ratio threshold, and look up the table to obtain the adjustment range of the shaping hot air temperature and / or the adjustment range of the fabric conveying speed corresponding to the level;

[0033] B3, increase the setting hot air temperature adjustment range in the control conditions associated with the current time period, and / or decrease the fabric conveying speed adjustment range in the control conditions associated with the current time period, while maintaining the setting tension in the control conditions associated with the current time period, and use the adjusted control conditions as the control conditions for the dyeing and finishing machine in the next time period.

[0034] Preferably, when the failure to achieve the expected setting control effect is of the type "the ratio is greater than or equal to the second ratio threshold", in step L2, the control conditions for the dyeing and finishing machine in the next time period are determined according to the second preset strategy. The specific method includes the following steps:

[0035] C1, determine whether the ratio is greater than the second ratio threshold and less than or equal to the fourth ratio threshold.

[0036] If so, proceed to step C2;

[0037] If not, then prompt for manual intervention to set the control conditions for the next time period;

[0038] C2, calculate the level of the second ratio threshold interval between the second ratio threshold and the fourth ratio threshold, and look up the table to obtain the adjustment range of the shaping hot air temperature and / or the adjustment range of the fabric conveying speed corresponding to the level;

[0039] C3, reduce the setting hot air temperature adjustment range in the control conditions associated with the current time period, and / or increase the fabric conveying speed adjustment range in the control conditions associated with the current time period, while maintaining the setting tension in the control conditions associated with the current time period, and use the adjusted control conditions as the control conditions for the dyeing and finishing machine in the next time period.

[0040] The present invention also provides an intelligent control system for a stenter, which can realize the aforementioned intelligent control method for the stenter.

[0041] The present invention has the following beneficial effects:

[0042] 1. By placing strain gauges at different points on the fabric, and by collecting and analyzing fabric state data and setting machine control deviation data generated within the transmission distance during the current time period in step L1, it becomes possible to quantify the influence of hot air temperature and fabric conveying speed on tension setting in the control conditions determined in step L1 in step L2.

[0043] 2. By setting the first ratio threshold range between the first ratio threshold and the third ratio threshold, the setting hot air temperature and fabric conveying speed set in the control conditions can affect the tension setting while keeping the tension applied to the fabric constant in the current time period. This allows the setting machine to analyze the fabric setting effect in the current time period and determine when the control conditions need to be adjusted in the next time period. Under the condition of keeping the tension constant, the setting hot air temperature and / or fabric conveying speed can be adjusted to optimize the fabric setting effect in the next time period.

[0044] 3. The ratio of the number of strain gauges to the total number of strain gauges is used to quantify the influence of the setting hot air temperature and the fabric conveying speed on the tension setting in the current period. This allows the setting machine to clearly define the setting control adjustment direction based on this influence in the next period, thereby automatically defining the setting control direction in different setting stages of the fabric and achieving a better setting effect.

[0045] 4. By setting the second ratio threshold range between the second ratio threshold and the fourth ratio threshold, the setting hot air temperature, fabric conveying speed and setting tension set in the control conditions have an adjustable relationship that influences the setting effect of the fabric. Thus, in the next stage, the machine can ensure the setting effect by adjusting the hot air temperature or the fabric conveying speed or the setting tension. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0052] In the description of this invention, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating a connection between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0053] This invention provides an intelligent control method for a stenter, such as... Figure 1 As shown, the steps include:

[0054] L1 determines the control conditions of the dyeing and finishing machine for the current time period, including finishing tension, finishing hot air temperature, and fabric conveying speed. Then, it collects and analyzes the fabric state data and finishing machine control deviation data generated within the conveying distance of the fabric in the current time period.

[0055] The control conditions for the current time period of the shaping machine are determined in step L2 under the "if not" condition. This will be explained in detail in subsequent steps L2, and will not be elaborated on again here.

[0056] For example, for a certain type of fabric, the setting tension is assumed to be 20 cN / cm, the setting hot air temperature is 180℃, and the fabric conveying speed is 25 meters per minute. Assuming the current time period lasts 10 seconds, the distance the fabric is conveyed during this time period is... rice.

[0057] In step L1, the fabric state data collected during the current time period includes: the resistance change collected by strain gauges placed at various points on the fabric at each data acquisition time during the current time period.

[0058] For example, assuming the data acquisition frequency is set to once per second, the data acquisition times are represented as follows: . Figure 2 Example diagrams showing strain gauges positioned at various locations on a fabric. exist The changes in resistance sensed at these 10 data acquisition moments are as follows: The strain gauge is then calculated according to the following formula (1). exist Stress values ​​at each data acquisition moment .

[0059]

[0060] In formula (1), This indicates the change in resistance of the strain gauge;

[0061] This indicates the initial resistance of the strain gauge;

[0062] This represents the sensitivity coefficient of the strain gauge;

[0063] This indicates the stress value of the strain gauge.

[0064] In step L1, the control deviation data of the fabric setting machine in the current time period includes: the absolute value of the difference between the tension at the corresponding point and the fabric tension applied to the fabric, calculated based on the fabric state data collected by the strain gauge at each point at each moment.

[0065] For example, Figure 2 Strain gauges in the example exist The tension of time ,in, Indicates strain gauge The elastic modulus; , They represent strain gauges. Initial resistance and sensitivity coefficient; Indicates strain gauge exist The change in resistance at any given time.

[0066] Assuming, If the tension applied to the fabric at any given time is 20 cN / cm, then... Constant strain gauge The control deviation of the setting machine at the fabric points in the deployed location is: .

[0067] It should be emphasized that in step L1, the control deviation data of the stenter obtained by analyzing and calculating the fabric in the current time period includes the control deviation of the stenter at each data acquisition time for the fabric position of each strain gauge placed on the fabric.

[0068] After completing step L1, the data on fabric state and setting machine control deviation generated within the current time period are collected, analyzed, and calculated. Figure 1 As shown, the intelligent control method for the stenter provided in this embodiment proceeds to the following steps:

[0069] L2, based on the control deviation data of the setting machine, determines whether the setting of the fabric under the control conditions determined in step L1 achieves the expected setting effect.

[0070] If so, the fabric will continue to be set under the same control conditions in the next consecutive time period.

[0071] If not, the control conditions for the dyeing and setting machine in the next time period will be determined according to the preset strategy.

[0072] In this embodiment, the method for determining whether the fabric setting under the control conditions of step L1 has achieved the expected setting control effect, based on the control deviation data of the setting machine calculated in step L1, specifically includes the following steps:

[0073] A1, calculate the average of the absolute values ​​of the differences calculated at different data acquisition times for the same strain gauge;

[0074] For example, regarding the strain gauges mentioned above... The absolute value of each difference calculated at each data collection time in the current time period. The average value is calculated using the following formula (2). :

[0075]

[0076] It is a natural number from 1 to 10.

[0077] A2, for each absolute value of the difference associated with the same strain gauge, determine whether the number of values ​​deviating from the average value associated with that strain gauge exceeds a preset threshold.

[0078] If so, the strain gauge is determined to be abnormal.

[0079] If not, then the strain gauge is considered to be under normal strain.

[0080] For example, strain gauges absolute value of the difference and If the absolute value of the difference is greater than the preset difference threshold, then it is determined that... Deviation When the strain gauge exist The absolute value of the difference calculated at these 10 data collection times Deviation If the number of strain gauges exceeds a preset threshold (e.g., 5), then the strain gauge is considered to be faulty. If the strain is abnormal, it is considered normal; otherwise, the strain is considered normal.

[0081] A3, determine whether the ratio of the number of strain gauges with strain anomalies to the total number of strain gauges is greater than a preset first ratio threshold and less than a preset second ratio threshold.

[0082] If so, then determine the control conditions determined in step L1, such as the setting tension of the fabric being 20cN / cm, the setting hot air temperature being 180℃, and the fabric conveying speed being 25 meters per minute, as mentioned above, and the setting of the fabric has achieved the expected setting control effect.

[0083] If not, the control conditions for the dyeing and setting machine in the next time period will be determined according to the preset strategy.

[0084] It should be noted that by setting a first ratio threshold range between the first and third ratio thresholds, the setting hot air temperature and fabric conveying speed set in the control conditions can influence tension setting while maintaining a constant tension applied to the fabric in the current time period. This allows the setting machine to analyze the fabric setting effect in the current time period and determine when adjustments to the control conditions are needed in the next time period, optimizing the fabric setting effect by adjusting the setting hot air temperature and / or fabric conveying speed while keeping the tension constant. It should also be noted that the method for the setting machine to analyze the fabric setting effect in the current time period can include existing image recognition methods, etc. Since the method for analyzing the fabric setting effect is not within the scope of the claims of this invention, it will not be specifically described.

[0085] By setting the second ratio threshold and the second ratio threshold range of the fourth ratio threshold, the setting hot air temperature, fabric conveying speed and setting tension set in the control conditions have an adjustable relationship that influences the setting effect of the fabric. Thus, in the next stage, the machine can ensure the setting effect by adjusting the hot air temperature or the fabric conveying speed or the setting tension.

[0086] The specific settings for the third and fourth ratio thresholds will be explained in detail below.

[0087] In this embodiment, by deploying strain gauges, two types of situations were observed where the expected shape control effect was not achieved. The first type is where the ratio of the number of strain gauges with abnormal strain to the total number of strain gauges is less than or equal to a first ratio threshold. The second type is where the ratio of the number of strain gauges with abnormal strain to the total number of strain gauges is greater than or equal to a second ratio threshold.

[0088] In response to the first type of situation where the expected setting control effect is not achieved, this embodiment determines the control conditions for the dyeing and finishing machine in the next time period according to the first preset strategy. The specific method includes the following steps:

[0089] B1, determine whether the ratio of the number of strain gauges with strain anomalies to the total number of strain gauges is greater than the third ratio threshold and less than or equal to the first ratio threshold.

[0090] If so, proceed to step B2;

[0091] If not, a prompt will appear indicating that manual intervention is required to set the control conditions for the next time period;

[0092] B2, calculate the level of the ratio that falls within the ratio threshold interval (defined as the first ratio threshold interval) formed between the first ratio threshold and the third ratio threshold, and look up the table to obtain the adjustment range of the setting hot air temperature and / or the adjustment range of the fabric conveying speed corresponding to the level;

[0093] For example, the first ratio threshold range is 0.2-0.3. Assuming that the data interval is 0.02 as a level, then the first ratio threshold range of 0.2-0.3 has 5 levels. Assuming that each level corresponds to the same adjustment range of the setting hot air temperature and the same adjustment range of the fabric conveying speed, for example, the adjustment range of the setting hot air temperature is 5℃ and the adjustment range of the fabric conveying speed is 2 meters / minute.

[0094] B3 is the adjustment range of the shaping hot air calculated in step B2 of the control conditions associated with the current time period, for example, adjusting the original shaping hot air temperature from 180℃ to 185℃.

[0095] And / or the fabric conveying speed adjustment calculated in step B2 of the control conditions associated with the current time period, for example, reducing the original fabric conveying speed from 25 meters per minute to 23 meters per minute;

[0096] The setting tension is maintained in the control conditions associated with the current time period, such as maintaining the setting tension at 20 cN / cm. Then, the setting hot air temperature of 185℃, the fabric conveying speed of 23 meters per minute, and the setting tension of 20 cN / cm are used as the control conditions for the dyeing and finishing machine in the next time period.

[0097] In response to the second type of situation where the expected setting control effect is not achieved, this embodiment determines the control conditions for the dyeing and finishing machine in the next time period according to the second preset strategy. The specific method includes the following steps:

[0098] C1 determines whether the ratio is greater than the second ratio threshold and less than or equal to the fourth ratio threshold.

[0099] If so, proceed to step C2;

[0100] If not, prompt for manual intervention to set control conditions for the next time period;

[0101] C2, calculate the level of the second ratio threshold range between the second ratio threshold and the fourth ratio threshold, and look up the table to obtain the adjustment range of the shaping hot air temperature and / or the adjustment range of the fabric conveying speed corresponding to the level;

[0102] The calculation of levels and the method of looking up the range table are the same as in step B2, and will not be repeated here.

[0103] C3, decreases the setting hot air temperature adjustment range in the control conditions associated with the current time period, and / or increases the fabric conveying speed adjustment range in the control conditions associated with the current time period, while maintaining the setting tension in the control conditions associated with the current time period, and uses the adjusted control conditions as the control conditions for the dyeing and finishing machine in the next time period.

[0104] The present invention also provides an intelligent control system for a setting machine, which embeds an algorithm for implementing the above-mentioned intelligent control method for a setting machine, so as to perform intelligent control of the dyeing and finishing setting machine.

[0105] In summary, this invention, by placing strain gauges at different points on the fabric, makes it possible to quantify the influence of the hot air temperature and fabric conveying speed on tension setting in the control conditions determined in step L1. By setting a first ratio threshold range between a first ratio threshold and a third ratio threshold, the setting hot air temperature and fabric conveying speed set in the control conditions can influence tension setting while maintaining a constant tension applied to the fabric in the current time period. By setting a second ratio threshold range between a second ratio threshold and a fourth ratio threshold, the setting hot air temperature, fabric conveying speed, and setting tension set in the control conditions have an adjustable relationship of mutual influence on the setting effect of the fabric. Thus, in the next stage, the machine can ensure the setting effect by adjusting the hot air temperature, fabric conveying speed, or setting tension.

[0106] It should be stated that the above-described specific embodiments are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to the present invention. However, such variations, as long as they do not depart from the spirit of the present invention, should be within the scope of protection of the present invention. Furthermore, some terminology used in this specification and claims is not limiting, but merely for ease of description.
