Description

Technical Field

[0001] The present invention relates to the technical field of power control of a texturing machine, and more particularly, to an anti-power-shaking control method and system for a texturing machine. Background Art

[0002] In the modern textile industry, texturing machines are essential production equipment, widely used in the processing of chemical fiber filaments. These machines utilize multiple motor units working in concert to perform fiber drafting, heating, cooling, and winding operations. However, in actual production, grid voltage fluctuations, commonly known as power fluctuations, are a common problem. Power fluctuations can cause unstable voltage within the texturing machine's motor units, disrupting normal operation and potentially causing equipment failure, reducing production efficiency, and increasing costs.

[0003] Existing texturing machines typically rely on a single power supply and lack effective voltage stabilization measures. When the grid voltage fluctuates, the voltage of the texturing machine's motor unit fluctuates accordingly, resulting in unstable motor speed and affecting product quality. Furthermore, while some texturing machines are equipped with voltage stabilizers, these regulators can only compensate for voltage fluctuations in a single motor and are unable to effectively address voltage fluctuations when multiple motor units operate in concert. Technically, existing voltage stabilization measures are mostly based on simple voltage detection and feedback control, lacking comprehensive analysis of the motor unit's operating sequence and voltage fluctuation curves, making it difficult to achieve accurate voltage compensation.

[0004] In the process of implementing the embodiments of the present invention, the inventors found that there are at least the following problems or defects in the prior art: the anti-electrical shaking measures of the existing texturizing machine cannot effectively cope with the complex voltage fluctuations when multiple motor groups work together, and lack of comprehensive analysis of the operating sequence of the motor groups and the voltage fluctuation curves, resulting in inaccurate voltage compensation and inability to effectively ensure the stable operation of the texturizing machine. Summary of the Invention

[0005] The present invention provides an anti-electricity shaking control method and system for a texturizing machine.

[0006] In a first aspect of the present invention, a method for controlling power sway prevention in a texturing machine is provided, comprising:

[0007] Obtain the texturing motor groups and their operating order included in each working mode of the texturing machine;

[0008] Real-time monitoring of the voltage signal under each working mode, and performing sliding window sampling on the voltage of each springing motor group to obtain the voltage fluctuation curve of each time window of each springing motor group arranged in chronological order;

[0009] Selecting the spring-loaded motor groups that operate in a fixed order in each working mode, arranging the voltage data of the spring-loaded motor groups that operate in a fixed order according to the operating order, and forming a voltage fluctuation curve of the spring-loaded motor groups in each working mode;

[0010] Find adjacent elastic motor groups whose voltage differences in adjacent time windows are greater than a preset threshold value from the voltage fluctuation curve of the elastic motor groups in each working mode, and use the elastic motor group with the lower voltage among the adjacent elastic motor groups as the group to be stabilized;

[0011] Using the backup power supply unit in the working mode and / or outside, the voltage compensation of the voltage stabilizing unit is performed and the compensated elastic motor unit is connected in parallel;

[0012] Based on the compensated parallel combination of the springing motor groups and the operating order of the springing motor groups, the final operating order of the springing motor groups in the working mode is obtained to implement the anti-electrical shaking control method.

[0013] Furthermore, the texturizing motor groups that operate in a fixed order refer to texturizing motor groups that operate in series or in parallel in a fixed order based on the process flow set in the working mode.

[0014] Furthermore, the preset threshold is specifically 1 / 2 of the maximum value of the working voltage fluctuation of the texturizing machine.

[0015] Furthermore, the voltage of each springing motor group is sampled by sliding windows to obtain voltage fluctuation curves of each time window of each springing motor group arranged in chronological order, specifically including:

[0016] The voltage is sampled at a preset frequency, and the sampled voltage data is windowed with a preset window length to obtain the mean voltage of each window;

[0017] Based on the window voltage average values, the time window voltage fluctuation curves of the springing motor groups arranged in time sequence are obtained.

[0018] Furthermore, the preset frequency is specifically 200 Hz.

[0019] Furthermore, the preset window length is specifically 5ms.

[0020] Furthermore, the voltage compensation is performed on the unit to be stabilized to obtain a parallel combination of the compensated elastic motor units, specifically comprising:

[0021] Find the backup power supply units within the current working mode and the corresponding voltage fluctuation curves. If there are no available backup power supply units within the current working mode, find the backup power supply units outside the current working mode, and then exclude the backup power supply units whose voltage fluctuation curves are longer than the unit to be stabilized.

[0022] Align the voltage fluctuation curves of the remaining standby power units with the endpoints of the voltage fluctuation curves of the units to be stabilized one by one and integrate them in sequence according to the time window to obtain each integrated voltage fluctuation curve;

[0023] Determine whether there is an integrated voltage fluctuation curve and a corresponding backup power supply unit that simultaneously meets the following conditions. If so, connect the corresponding backup power supply unit and the unit to be stabilized in parallel as a compensated elastic generator unit. The conditions include:

[0026] If it does not exist, find the integrated voltage fluctuation curve and the corresponding backup power supply unit that does not exceed the limit threshold, and the voltage difference in the adjacent time window with the adjacent elastic generator unit is less than 0 and the absolute value exceeds the preset threshold from each integrated voltage fluctuation curve;

[0027] Determine whether there is a standby power supply unit that can complete voltage compensation by adjusting the output power among the corresponding standby power supply units. If so, connect the corresponding standby power supply unit and the unit to be stabilized in parallel as a compensated elastic motor unit;

[0028] If it does not exist, the integrated voltage fluctuation curve will be used as the voltage fluctuation curve of the unit to be stabilized, and the process will return to continue to find the remaining backup power supply units, integrate and judge, until the absolute value of the voltage difference between the voltage fluctuation curve of the unit to be stabilized and the adjacent time window of the adjacent elastic motor unit is less than the preset threshold value, and all the corresponding backup power supply units obtained will be combined in parallel with the unit to be stabilized as the compensated elastic motor unit to implement the anti-sway control method.

[0029] Furthermore, the process of obtaining the final operating order of the springing motor groups in the working mode based on the compensated parallel combination of the springing motor groups and the operating order of the springing motor groups specifically includes:

[0030] Based on the parallel combination of the springing motor groups and the operation order of the springing motor groups in the working mode, a voltage fluctuation curve of the springing motor group after the working mode is updated is obtained;

[0031] If there is an unused backup power supply unit in the working mode, the unused backup power supply unit is spliced ​​with the voltage fluctuation curve of the elastic motor unit after the working mode is updated, and it is judged whether there is an adjacent elastic motor unit with an adjacent time window voltage difference greater than a preset threshold in the spliced ​​voltage fluctuation curve of the elastic motor unit. If so, the operations of finding the backup power supply unit, integrating and judging are repeated to obtain a parallel combination of the elastic motor units. Then, based on the parallel combination of the elastic motor units, the spliced ​​voltage fluctuation curve of the elastic motor unit is updated to obtain the voltage fluctuation curve of the overall elastic motor unit in the working mode. If not, the spliced ​​voltage fluctuation curve of the elastic motor unit is directly used as the voltage fluctuation curve of the overall elastic motor unit in the working mode.

[0032] If there is no unused backup power supply unit in the working mode, the updated voltage fluctuation curve of the elastic generator set is directly used as the voltage fluctuation curve of the overall elastic generator set in the working mode;

[0033] Determine whether the voltage data of the time windows corresponding to the two endpoints of the voltage fluctuation curve of the overall elastic motor group in the working mode exceeds a preset threshold. If so, find a backup power supply unit that meets the conditions from the backup power supply units inside and outside the working mode. The condition is that the voltage data of the backup power supply unit found has a voltage difference of an adjacent time window between the voltage data of one end adjacent to the endpoint exceeding the voltage threshold and the voltage data of the adjacent time window between the endpoint exceeding the preset threshold that does not exceed the preset threshold, and the voltage data of the other end does not exceed the preset threshold.

[0034] If no backup power supply unit that meets the conditions is found, then find a backup power supply unit with the smallest voltage difference in the adjacent time window with the endpoint exceeding the preset threshold and with adjustable output power, and adjust the output power to make the backup power supply unit meet the above conditions;

[0035] The voltage fluctuation curve of the standby power supply unit found is spliced ​​with one end of the voltage fluctuation curve of the overall elastic motor unit in the corresponding working mode to obtain the voltage fluctuation curve of the final elastic motor unit in the working mode;

[0036] The operation order of the final springing motor group in the working mode is obtained based on the voltage fluctuation curve of the final springing motor group in the working mode to implement the anti-electrical shaking control method.

[0037] In a second aspect of the present invention, there is provided an anti-swaying power control system for a texturing machine, comprising:

[0038] Voltage monitoring unit, unit for obtaining voltage of units to be stabilized, compensation unit and operation sequence obtaining unit;

[0039] The voltage monitoring unit is used to obtain the texturing motor groups included in each working mode of the texturing machine and the operating order of the texturing motor groups, monitor the voltage signals in each working mode in real time, and perform sliding window sampling on the voltage of each texturing motor group to obtain the voltage fluctuation curves of each time window of each texturing motor group arranged in chronological order;

[0040] The unit for acquiring the unit to be voltage-stabilized is configured to select the elastic motor groups running in a fixed order in each working mode, arrange the voltage data of the elastic motor groups running in a fixed order according to the order of operation, form a voltage fluctuation curve of the elastic motor groups in each working mode, and find adjacent elastic motor groups whose voltage differences in adjacent time windows are greater than a preset threshold value from the voltage fluctuation curve of the elastic motor groups in each working mode as the units to be voltage-stabilized;

[0041] The compensation unit is used to use the backup power supply unit in the working mode and / or outside to perform voltage compensation on the voltage stabilizing unit to obtain the compensated elastic motor unit in parallel combination;

[0042] The operation sequence acquisition unit obtains the final operation sequence of the springing motor groups in the working mode based on the compensated parallel combination of the springing motor groups and the operation sequence of the springing motor groups, so as to implement the anti-electrical shaking control method.

[0043] In the third aspect of the present invention, a texturing machine device with an anti-electrical shaking function is provided, the texturing machine device includes a control center, the control center stores the final operating order of the texturing motor group in the working mode, and the final operating order of the texturing motor group in the working mode is obtained by executing the anti-electrical shaking control method for the texturing machine described in any one of the first aspects.

[0044] The above embodiments of the present invention have at least the following beneficial effects:

[0045] (1) The present invention monitors the voltage signals in each working mode in real time and performs sliding window sampling on the voltage of the texturing motor group to form a voltage fluctuation curve arranged in time sequence, which can accurately identify the unit to be stabilized with large voltage fluctuation; at the same time, when obtaining the texturing motor groups included in each working mode of the texturing machine and the operating order of the texturing motor groups, it clarifies which motor groups are involved in the work and their operating order under different working states, providing basic data for subsequent voltage monitoring and compensation, ensuring that the relevant motor groups can be accurately processed when the voltage fluctuates; it can be seen that it conducts a comprehensive analysis of the operating order of the motor groups and the voltage fluctuation curve, which can ensure that the voltage compensation is sufficiently accurate and effectively guarantee the stable operation of the texturing machine;

[0046] (2) The present invention utilizes the backup power supply units inside and outside the working mode to perform voltage compensation, and combines it with the optimization of the operating sequence to achieve accurate voltage compensation for the texturing motor units, ensuring that each motor unit can still operate stably when the voltage fluctuates, thereby improving the production efficiency and product quality of the texturing machine; specifically, it obtains the final texturing motor unit operating sequence in the working mode based on the parallel combination of the compensated texturing motor units and the operating sequence of the texturing motor units, and ensures the stable operation of the texturing machine under voltage fluctuations by optimizing the operating sequence and parallel combination of the motor units; after considering the voltage compensation, each motor unit operates in a new sequence to achieve the best operating effect;

[0047] (3) The present invention can also flexibly adjust the operating sequence and parallel combination of the texturizing motor sets according to different operating modes and voltage fluctuations. This dynamic adjustment mechanism can maximize the voltage compensation capability of the backup power supply set, avoiding equipment downtime and production interruptions caused by voltage fluctuations. At the same time, through strict condition judgment and optimization algorithms, it is ensured that the compensated voltage fluctuation curve meets the preset threshold requirements, which can further enhance the adaptability and reliability of the texturizing machine in complex power grid environments.

[0052] The principles and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are provided solely to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0053] Those skilled in the art will appreciate that the embodiments of the present invention may be implemented as a system, apparatus, device, method, or computer program product. Therefore, the present invention may be implemented in the following forms: entirely in hardware, entirely in software (including firmware, resident software, microcode, etc.), or in a combination of hardware and software.

[0054] It should be noted that any number of elements in the drawings is for illustration only and not for limitation, and any naming is only for distinction and does not have any limiting meaning.

[0055] Reference below Figure 1 , Figure 1 The flowchart of the anti-electrical shaking control method for a texturing machine provided by one embodiment of the present invention is as follows. Figure 1 As shown, a method for controlling power sway prevention for a texturing machine includes:

[0056] S1 obtains the texturing motor groups and the operating order of the texturing motor groups included in each working mode of the texturing machine;

[0057] S2 monitors the voltage signal in each working mode in real time, and performs sliding window sampling on the voltage of each spring motor group to obtain the voltage fluctuation curve of each time window of each spring motor group arranged in chronological order;

[0058] S3 selects the springing motor groups running in a fixed order in each working mode, arranges the voltage data of the springing motor groups running in a fixed order according to the running order, and forms a voltage fluctuation curve of the springing motor groups in each working mode;

[0059] S4 finds adjacent elastic motor groups whose voltage differences in adjacent time windows are greater than a preset threshold value from the voltage fluctuation curve of the elastic motor groups in each working mode, and selects the elastic motor group with the lower voltage among the adjacent elastic motor groups as the group to be stabilized;

[0060] S5 uses the backup power supply unit inside and / or outside the working mode, and the voltage compensation of the voltage stabilizing unit is carried out to obtain the compensated elastic motor unit in parallel combination;

[0061] S6 obtains the final springing motor group operation order of the working mode based on the compensated springing motor group parallel combination and the springing motor group operation order to implement the anti-electrical shaking control method.

[0062] It should be noted that when obtaining the texturing motor groups included in each working mode of the texturing machine and the operating order of the texturing motor groups, the main purpose is to clarify which motor groups are involved in the work and their operating order under different working conditions. The texturing motor group refers to the collection of motors used to drive different process links in the texturing machine, such as the drafting motor group, the heating motor group, etc. These motor groups work together according to a certain process flow. The operating order refers to the order in which these motor groups are started and run under the working mode. For example, in the preheating mode, the heating motor group may start first, and then the drafting motor group. By obtaining this information, basic data can be provided for subsequent voltage monitoring and compensation, ensuring that the relevant motor groups can be accurately handled when the voltage fluctuates.

[0063] Specifically, real-time monitoring of voltage signals under various operating modes involves continuously acquiring voltage data from the spring-loaded motor units through devices such as voltage sensors. Sliding window sampling is a signal processing method that segments voltage data to produce voltage fluctuation curves for each time window arranged in chronological order. Sliding window sampling here refers to the use of a fixed-length window for moving sampling within the time series of the voltage signal. Window length and sampling frequency are two key parameters. For example, the preset frequency can be set to 200Hz, meaning 200 samples are taken per second, and the preset window length can be set to 5ms, meaning each sampling window covers a 5-millisecond period. In this way, the continuous voltage signal is converted into discrete voltage data points, and the voltage mean within each window is calculated to produce the voltage fluctuation curves for each spring-loaded motor unit. These curves intuitively reflect the changes in voltage over time, providing a basis for subsequent voltage difference calculations and the identification of units to be stabilized.

[0064] Preferably, to identify the motor groups to be stabilized, adjacent motor groups whose voltage differences between adjacent time windows exceed a preset threshold can be identified from the voltage fluctuation curve of the texturing motor groups in each operating mode. The preset threshold can be set based on the actual operating voltage range and process requirements of the texturing machine; for example, it can be set to half of the maximum voltage fluctuation of the texturing machine. Thus, when the voltage difference between adjacent time windows exceeds this threshold, it can be considered that the voltage fluctuation of this motor group is large and requires voltage stabilization. Selecting the motor groups with lower voltage as the motor groups to be stabilized prioritizes compensating for motor groups with insufficient voltage, ensuring normal operation. Furthermore, when performing voltage compensation, backup power supply units within and / or outside the operating mode can be utilized. A backup power supply unit is a power supply device that does not participate in the main operation under normal operating mode but can provide additional voltage support during voltage fluctuations. By connecting the backup power supply unit in parallel with the motor groups to be stabilized and adjusting the operating order based on the compensated voltage fluctuation curve, effective voltage compensation can be achieved for the motor groups to be stabilized, thereby improving the operational stability of the texturing machine under voltage fluctuations.

[0065] In some embodiments, the texturizing motor groups that operate in a fixed order refer to texturizing motor groups that operate in series or in parallel in a fixed order based on the process flow set in the working mode.

[0066] It should be noted that fixed-sequence texturing motor groups refer to motor groups that are started and operated sequentially according to a predetermined process flow under a specific operating mode of the texturing machine. This mode of operation ensures the coordinated operation of the various process links of the texturing machine. For example, during processes such as drafting, heating, and winding, the motor groups need to be started and operated in a certain order to ensure the continuity and quality of fiber processing. Fixed-sequence texturing motor groups can operate in series, that is, the output of one motor group serves as the input of the next motor group, or in parallel, that is, multiple motor groups work simultaneously to jointly complete a certain process link. In this way, the stable operation of the texturing machine can be ensured under different operating modes, while providing a clear target for monitoring and compensating for voltage fluctuations.

[0067] Specifically, the texturing motor groups that operate in a fixed sequence have different operating modes under different working modes. For example, in preheating mode, the heating motor group may start first, followed by the stretching motor group. This sequential startup method is considered series operation. In normal production mode, multiple motor groups may start simultaneously and work together, which is considered parallel operation. When operating in series, the startup sequence and running time of the motor groups are key parameters. For example, the heating motor group needs to start 10 minutes in advance to reach the preset temperature, and then the stretching motor group is started. When operating in parallel, the power distribution and coordinated control of each motor group are key. For example, multiple motor groups need to adjust the speed synchronously to ensure the tension of the fiber. The choice of these operating modes depends on the specific process requirements and production process of the texturing machine. By clarifying the operating sequence and method of the motor groups, voltage fluctuations can be better monitored and targeted compensation can be made.

[0068] Preferably, during implementation, the operating parameters of the texturing motor groups, which operate in a fixed sequence, can be further refined based on the specific process flow and production requirements of the texturing machine. For example, when operating in series, a startup delay can be set for each motor group to ensure that the previous motor group reaches a stable operating state before the next motor group starts. When operating in parallel, the power distribution ratio of each motor group can be set, and sensors can be used to monitor the current and voltage of each motor group in real time to ensure power balance among the motor groups during parallel operation.

[0069] Furthermore, by establishing a motor unit operation model and inputting parameters such as the motor unit's rated power, starting current, and operating voltage, we can simulate voltage fluctuations under different operating modes, providing a more accurate basis for voltage compensation. Through these detailed measures, the operating stability and production efficiency of the texturing machine can be further improved under voltage fluctuations.

[0070] In some embodiments, the preset threshold is specifically 1 / 2 of the maximum value of the working voltage fluctuation of the texturizing machine.

[0071] It should be noted that the preset threshold is a key parameter used to determine whether the voltage fluctuation of the texturing motor unit exceeds the normal range. Specifically, the preset threshold is set to 1 / 2 of the maximum operating voltage fluctuation of the texturing machine. This setting is based on the maximum voltage fluctuation range that the texturing machine can withstand during normal operation. When the voltage difference between adjacent time windows exceeds this threshold, it indicates that the voltage fluctuation of the motor unit has exceeded the normal range and requires voltage stabilization. This setting takes into account both the operational stability of the texturing machine and the timeliness and effectiveness of voltage compensation, ensuring that measures can be taken quickly to ensure the normal operation of the equipment when the voltage fluctuation is large.

[0072] Specifically, the maximum operating voltage fluctuation of the texturing machine refers to the maximum voltage variation range that the texturing machine can withstand during normal operation. For example, if the rated operating voltage of the texturing machine is 380V, its maximum allowable voltage fluctuation range is ±10%, that is, 342V to 418V. Within this range, the texturing machine can operate normally without being significantly affected by voltage fluctuations. The preset threshold is set to half of this maximum voltage fluctuation range, that is, ±5%, or 19V. This means that when the voltage difference between adjacent time windows exceeds 19V, the system will determine that the voltage fluctuation of the motor group is too large and requires compensation. This setting can effectively distinguish between normal voltage fluctuations and abnormal voltage fluctuations, providing a clear judgment basis for subsequent voltage compensation.

[0073] Preferably, in practical applications, the setting of the preset threshold value can be further optimized according to the specific model and process requirements of the texturing machine. For example, for some texturing machines with higher voltage stability requirements, the preset threshold value can be set smaller to improve the sensitivity of the system. At the same time, by establishing a voltage fluctuation model and inputting parameters such as the rated voltage of the texturing machine and the maximum allowable voltage fluctuation range, the voltage fluctuation conditions under different working modes can be simulated, thereby more accurately determining the preset threshold value. In addition, during the data processing process, the voltage sampling data can be filtered to reduce the impact of noise on the voltage fluctuation judgment. Through these refined measures, the stability and reliability of the system can be further improved, ensuring that the texturing machine can operate stably under various voltage fluctuation conditions.

[0074] In some embodiments, performing sliding window sampling on the voltage of each springing motor group to obtain the voltage fluctuation curves of each time window of each springing motor group arranged in chronological order specifically includes:

[0075] The voltage is sampled at a preset frequency, and the sampled voltage data is windowed with a preset window length to obtain the mean voltage of each window;

[0076] Based on the average values ​​of the window voltages, the voltage fluctuation curves of the time windows of the springing motor groups arranged in time sequence are obtained.

[0077] It should be noted that the sliding window sampling of the voltage of each elastic motor group is to obtain the voltage fluctuation curve of each time window arranged in chronological order. Sliding window sampling is a signal processing technology that obtains the voltage fluctuation by moving a window of fixed length on the time series of the voltage signal and sampling and processing the voltage data within the window. This method can effectively capture the instantaneous changes in voltage and convert them into discrete data points for subsequent analysis and processing. The preset frequency refers to the sampling frequency, that is, the number of samples per unit time, and the preset window length refers to the size of the sliding window, that is, the time range covered by each sampling. The voltage fluctuation curve obtained by sliding window sampling can intuitively reflect the voltage changes of the elastic motor group in different time windows, providing data support for the subsequent voltage difference calculation and the determination of the unit to be stabilized.

[0078] Specifically, the preset frequency refers to the frequency of voltage sampling. For example, it can be set to 200 Hz, or 200 samples per second. This means that the system samples the voltage signal 200 times per second, obtaining 200 voltage data points. The preset window length refers to the size of the sliding window. For example, it can be set to 5 ms, meaning that each sampling window covers a 5-millisecond period. Within this window, the system calculates the voltage mean of all sampling points within the window to obtain the average voltage value within that time window. In this way, the continuous voltage signal is converted into discrete voltage data points, forming voltage fluctuation curves for each time window arranged in chronological order. These curves can intuitively reflect the voltage changes over time, providing a basis for subsequent voltage difference calculation and identification of the generator set to be stabilized. For example, if the voltage mean suddenly drops within a certain time window, this indicates that the voltage of the generator set has fluctuated, requiring further analysis and processing.

[0079] Preferably, during implementation, the sliding window sampling parameter settings can be further optimized based on the specific operating conditions and voltage fluctuation characteristics of the texturing machine. For example, for texturing motor units with frequent voltage fluctuations, the sampling frequency can be appropriately increased, for example, to 300 Hz or higher, to more accurately capture instantaneous voltage changes. Furthermore, the sliding window length can be adjusted based on the texturing machine's process requirements and voltage fluctuation range, for example, to 3 ms or shorter, to more quickly respond to voltage changes.

[0080] Furthermore, during data processing, the sampled voltage data can be filtered to reduce the impact of noise on the voltage fluctuation curve. Through these refined measures, the system's monitoring accuracy and response speed can be further improved, ensuring the stable operation of the texturing machine under voltage fluctuations.

[0081] In some embodiments, the preset frequency is specifically 200 Hz.

[0082] It should be noted that the preset frequency refers to the frequency at which the voltage signal is sampled during the sliding window sampling process. The sampling frequency determines the number of voltage data points collected per unit time. A higher sampling frequency can more accurately capture instantaneous voltage changes, thereby more accurately reflecting voltage fluctuations. In the present invention, the preset frequency is specifically set to 200Hz, or 200 samples per second. This frequency setting is determined after comprehensively considering the voltage fluctuation characteristics and data processing capabilities of the texturing machine. It aims to ensure data accuracy while avoiding the burden of excessive data volume on system processing capabilities.

[0083] Specifically, the sampling frequency is a key parameter in the sliding window sampling process. For example, when the sampling frequency is set to 200 Hz, the system samples the voltage signal 200 times per second, acquiring 200 voltage data points. These data points can be used to calculate the voltage mean within each sliding window, thereby generating a chronological voltage fluctuation curve. The choice of sampling frequency needs to be determined based on the actual operating conditions of the texturing machine and the characteristics of the voltage fluctuations. If the voltage fluctuations of the texturing machine are more severe, a higher sampling frequency is required to capture these rapid changes; if the voltage fluctuations are relatively stable, the sampling frequency can be appropriately lowered to reduce the amount of data processing. Furthermore, the sampling frequency is also related to the sliding window length. The sliding window length determines the time range covered by each sampling, while the sampling frequency determines the number of data points collected within that time range.

[0084] Preferably, during implementation, the sampling frequency setting can be further optimized based on the specific operating environment and voltage fluctuation characteristics of the texturing machine. For example, if the texturing machine operates in a power grid environment with frequent voltage fluctuations, the sampling frequency can be increased to 300 Hz or higher to more accurately capture instantaneous voltage changes. At the same time, the most suitable combination of sampling frequency and sliding window length can be determined through experiments and data analysis. For example, by comparing the voltage fluctuation curves generated at different sampling frequencies, the sampling frequency that most accurately reflects the actual voltage fluctuations can be selected. In addition, during data processing, the collected voltage data can be filtered to reduce the impact of noise on the voltage fluctuation curve, thereby improving the monitoring accuracy and reliability of the system.

[0085] In some embodiments, the preset window length is specifically 5 ms.

[0086] It should be noted that the preset window length refers to the time range covered by each sampling during the sliding window sampling process. The choice of window length directly affects the smoothness of the voltage fluctuation curve and its sensitivity to instantaneous changes. In the present invention, the preset window length is specifically set to 5ms. This setting is intended to balance the smoothness of the data and the ability to respond to rapid changes in voltage. A shorter window length can reflect instantaneous changes in voltage more quickly, but may introduce more noise; a longer window length will make the curve smoother, but may delay the response to rapid changes. Therefore, a window length of 5ms is an optimized compromise that can effectively capture voltage fluctuations while ensuring data accuracy.

[0087] Specifically, the window length in sliding window sampling is a key parameter, determining the time period covered by each sampling operation. For example, when the window length is set to 5ms, the voltage mean of all sampling points within this 5ms period is calculated for each sampling operation. This mean represents the average voltage level within that time window, thus forming a chronological voltage fluctuation curve. The choice of window length needs to be determined based on the actual operating conditions of the texturing machine and the characteristics of the voltage fluctuations. If the voltage fluctuations are severe and frequent, a shorter window length, such as 3ms, may be more suitable to capture transient changes more quickly. If the voltage fluctuations are relatively stable, a longer window length, such as 10ms, can smooth the curve and reduce the impact of noise. Furthermore, the window length is closely related to the sampling frequency. The sampling frequency determines the number of data points collected within the window, while the window length determines the time span of these data points.

[0088] Preferably, in practical applications, the window length setting can be further optimized based on the specific operating environment and voltage fluctuation characteristics of the texturing machine. For example, if the texturing machine operates in a power grid environment with frequent and large voltage fluctuations, the window length can be shortened to 3ms or shorter to improve responsiveness to rapid changes. Furthermore, the most suitable window length can be determined through experimentation and data analysis. For example, by comparing voltage fluctuation curves generated under different window lengths, the window length that most accurately reflects the actual voltage fluctuations can be selected. Furthermore, during data processing, the collected voltage data can be filtered to reduce the impact of noise on the voltage fluctuation curve, thereby improving the monitoring accuracy and reliability of the system.

[0089] In some embodiments, performing voltage compensation on the unit to be voltage-stabilized to obtain a parallel combination of compensated elastic motor units specifically includes:

[0090] Find the backup power supply units within the current working mode and the corresponding voltage fluctuation curves. If there are no available backup power supply units within the current working mode, find the backup power supply units outside the current working mode, and then exclude the backup power supply units whose voltage fluctuation curves are longer than the unit to be stabilized.

[0091] Align the voltage fluctuation curves of the remaining standby power units with the endpoints of the voltage fluctuation curves of the units to be stabilized one by one and integrate them in sequence according to the time window to obtain each integrated voltage fluctuation curve;

[0092] Determine whether there is an integrated voltage fluctuation curve and a corresponding backup power supply unit that simultaneously meets the following conditions. If so, connect the corresponding backup power supply unit and the unit to be stabilized in parallel as a compensated elastic generator unit. The conditions include:

[0093] The corresponding integrated voltage fluctuation curve does not exceed the limit threshold;

[0094] The absolute value of the voltage difference between the corresponding integrated voltage fluctuation curve and the adjacent time window voltage of the adjacent elastic generator group does not exceed the preset threshold;

[0095] If it does not exist, find the integrated voltage fluctuation curve and the corresponding backup power supply unit that does not exceed the limit threshold, and the voltage difference in the adjacent time window with the adjacent elastic generator unit is less than 0 and the absolute value exceeds the preset threshold from each integrated voltage fluctuation curve;

[0096] Determine whether there is a standby power supply unit that can complete voltage compensation by adjusting the output power among the corresponding standby power supply units. If so, connect the corresponding standby power supply unit and the unit to be stabilized in parallel as a compensated elastic motor unit;

[0097] If it does not exist, the integrated voltage fluctuation curve will be used as the voltage fluctuation curve of the unit to be stabilized, and the process will return to continue to find the remaining backup power supply units, integrate and judge, until the absolute value of the voltage difference between the voltage fluctuation curve of the unit to be stabilized and the adjacent time window of the adjacent elastic motor unit is less than the preset threshold value, and all the corresponding backup power supply units obtained will be combined in parallel with the unit to be stabilized as the compensated elastic motor unit to implement the anti-sway control method.

[0098] It should be noted that the process of voltage compensation for the unit to be stabilized is the core link in implementing the anti-sway control method. This process involves multiple steps, such as screening the backup power supply unit, integrating the voltage fluctuation curve, and condition judgment. The backup power supply unit is a power supply device that is on standby during normal operation but can provide additional voltage support during voltage fluctuations. By combining the backup power supply unit in parallel with the unit to be stabilized and selecting the appropriate backup power supply unit based on specific conditions, the voltage shortage can be effectively compensated and the stable operation of the texturizing unit can be ensured. This process not only requires considering the matching of the voltage fluctuation curve, but also ensures that the compensated voltage fluctuation does not exceed the limit threshold, thereby ensuring the normal operation of the texturizing machine under voltage fluctuations.

[0099] Specifically, the process of performing voltage compensation on the target voltage-stabilized unit includes the following key steps. First, the backup power units within the current operating mode must be identified and their corresponding voltage fluctuation curves obtained. If no backup power units are available within the current operating mode, a search must be conducted for backup power units outside of the current operating mode. When screening backup power units, those with voltage fluctuation curves longer than the target voltage-stabilized unit must be excluded, as such units may not effectively match the voltage fluctuation characteristics of the target voltage-stabilized unit. Next, the voltage fluctuation curves of the remaining backup power units are aligned with the endpoints of the target voltage-stabilized unit's voltage fluctuation curve one by one and integrated sequentially by time window to obtain integrated voltage fluctuation curves. The integrated voltage fluctuation curves must meet two conditions: first, they must not exceed the clipping threshold, and second, the absolute value of the voltage difference with adjacent boosted units within adjacent time windows must not exceed a preset threshold. If a backup power unit meeting these conditions exists, it is connected in parallel with the target voltage-stabilized unit to complete voltage compensation. If there is no backup power supply unit that fully meets the requirements, further screening and adjustment are required, such as selecting a backup power supply unit with adjustable output power and meeting the compensation requirements by adjusting its output power.

[0100] Preferably, in the process of implementing voltage compensation, some operating steps can be further refined to improve the accuracy and reliability of compensation. For example, when screening backup power supply units, priority can be given according to the power capacity and voltage stability of the backup power supply units, and priority should be given to backup power supply units with larger power and stable voltage. When integrating the voltage fluctuation curve, an interpolation algorithm can be used to deal with the problem of curve endpoint alignment to ensure that the integrated curve is smoother and more accurate. In addition, a voltage compensation model can be established, and the input parameters include the voltage fluctuation curve of the unit to be stabilized, the voltage fluctuation curve of the backup power supply unit, the limiting threshold and the preset threshold, etc. Through model calculation and optimization, the optimal backup power supply unit is selected for parallel combination. During the data processing process, the integrated voltage fluctuation curve can be smoothed to reduce the mutation caused by curve splicing, thereby further improving the stability and reliability of the system.

[0101] In some embodiments, the process of obtaining the final operating order of the springing motor groups in the working mode based on the compensated parallel combination of the springing motor groups and the operating order of the springing motor groups specifically includes:

[0102] Based on the parallel combination of the springing motor groups and the operation order of the springing motor groups in the working mode, a voltage fluctuation curve of the springing motor group after the working mode is updated is obtained;

[0103] If there is an unused backup power supply unit in the working mode, the unused backup power supply unit is spliced ​​with the voltage fluctuation curve of the elastic motor unit after the working mode is updated, and it is judged whether there is an adjacent elastic motor unit with an adjacent time window voltage difference greater than a preset threshold in the spliced ​​voltage fluctuation curve of the elastic motor unit. If so, the operations of finding the backup power supply unit, integrating and judging are repeated to obtain a parallel combination of the elastic motor units. Then, based on the parallel combination of the elastic motor units, the spliced ​​voltage fluctuation curve of the elastic motor unit is updated to obtain the voltage fluctuation curve of the overall elastic motor unit in the working mode. If not, the spliced ​​voltage fluctuation curve of the elastic motor unit is directly used as the voltage fluctuation curve of the overall elastic motor unit in the working mode.

[0104] If there is no unused backup power supply unit in the working mode, the updated voltage fluctuation curve of the elastic generator set is directly used as the voltage fluctuation curve of the overall elastic generator set in the working mode;

[0105] Determine whether the voltage data of the time windows corresponding to the two endpoints of the voltage fluctuation curve of the overall elastic motor group in the working mode exceeds a preset threshold. If so, find a backup power supply unit that meets the conditions from the backup power supply units inside and outside the working mode. The condition is that the voltage data of the backup power supply unit found has a voltage difference of an adjacent time window between the voltage data of one end adjacent to the endpoint exceeding the voltage threshold and the voltage data of the adjacent time window between the endpoint exceeding the preset threshold that does not exceed the preset threshold, and the voltage data of the other end does not exceed the preset threshold.

[0106] If no backup power supply unit that meets the conditions is found, then find a backup power supply unit with the smallest voltage difference in the adjacent time window with the endpoint exceeding the preset threshold and with adjustable output power, and adjust the output power to make the backup power supply unit meet the above conditions;

[0107] The voltage fluctuation curve of the standby power supply unit found is spliced ​​with one end of the voltage fluctuation curve of the overall elastic motor unit in the corresponding working mode to obtain the voltage fluctuation curve of the final elastic motor unit in the working mode;

[0108] The operation order of the final springing motor group in the working mode is obtained based on the voltage fluctuation curve of the final springing motor group in the working mode to implement the anti-electrical shaking control method.

[0109] It should be noted that the process of obtaining the final operating order of the texturizing motor groups in the working mode based on the parallel combination of the compensated texturizing motor groups and the operating order of the texturizing motor groups is a key step in realizing the anti-sway control method. This process aims to ensure the stable operation of the texturizing machine under voltage fluctuations by optimizing the operating order and parallel combination of the motor groups. The final operating order of the texturizing motor groups in the working mode means that after considering the voltage compensation, each motor group operates in a new order to achieve the best operating effect. This process not only needs to consider the parallel combination of the motor groups after voltage compensation, but also needs to consider the rational use of the unused backup power supply units, as well as the splicing and optimization of the voltage fluctuation curve to ensure the stability and reliability of the entire texturizing machine system.

[0110] Specifically, determining the final operating order of the elastic motor groups in the working mode involves multiple steps. First, based on the compensated parallel combination of the elastic motor groups and the original operating order of the elastic motor groups, the voltage fluctuation curve of the elastic motor groups after the working mode is updated is obtained. The purpose of this step is to evaluate the current voltage stability through the voltage fluctuation curve of the motor groups after the parallel combination. If there are unused backup power supply units in the working mode, it is necessary to splice these backup power supply units with the updated voltage fluctuation curve and determine whether the voltage difference between adjacent time windows in the spliced ​​curve is greater than a preset threshold. If so, it is necessary to repeat the screening, integration and judgment operations of the backup power supply units to further optimize the parallel combination. Finally, through these steps, the voltage fluctuation curve of the overall elastic motor group in the working mode is obtained, and the final operating order of the elastic motor groups is determined based on this curve. This process needs to consider multiple parameters, including the splicing points of the voltage fluctuation curve, the voltage difference between adjacent time windows, and the output power of the backup power supply unit.

[0111] Preferably, during the implementation process, some operating steps can be further refined to improve the stability and reliability of the system. For example, when splicing the voltage fluctuation curve, a smooth transition algorithm can be used to ensure the continuity and smoothness of the curve at the splicing point, reducing the voltage mutation caused by splicing. When selecting a backup power supply unit, priority can be given according to the adjustability of its output power and voltage stability, and priority should be given to backup power supply units with larger power and stable voltage. In addition, an operation order optimization model can be established, and the input parameters include the parallel combination of compensated elastic motor units, the voltage fluctuation curve of the unused backup power supply unit, the preset threshold, etc. The optimal operation order of the elastic motor unit is determined through model calculation and optimization. During the data processing process, the updated voltage fluctuation curve can be filtered to reduce the impact of noise on the voltage fluctuation curve, thereby further improving the monitoring accuracy and reliability of the system.

[0112] The aforementioned embodiments of the present invention have the following beneficial effects: The anti-power-sway control method can monitor voltage fluctuations in all operating modes of the texturing machine in real time. Using sliding window sampling technology, it accurately captures abnormal voltage changes and automatically identifies units requiring voltage stabilization based on preset thresholds. By intelligently matching backup power units for dynamic voltage compensation, the texturing motor units can maintain stable operation despite voltage fluctuations, avoiding equipment downtime or production interruptions caused by voltage instability. Furthermore, this method can optimize the unit operating sequence, ensuring that the entire system continues to operate according to the optimal process after voltage compensation, thereby improving production efficiency.

[0113] Furthermore, this method flexibly utilizes backup power resources within and outside of the operating mode, ensuring effective voltage compensation through multiple rounds of screening and power regulation. Even in the face of extreme voltage fluctuations, the system can maintain a stable power supply by dynamically adjusting the output power of backup units. The resulting optimized operating sequence ensures continuous and reliable operation of the texturing machine under complex operating conditions, reduces production losses caused by voltage fluctuations, and improves the equipment's overall anti-interference capabilities.
