Description

Technical Field

[0001] This invention relates to the field of power control technology for texturing machines, and more specifically, to a method and system for preventing power fluctuations in texturing machines. Background Technology

[0002] In the modern textile industry, texturing machines are an important production piece of equipment widely used in the processing of synthetic fiber filaments. Texturing machines utilize multiple motor units working in tandem to perform processes such as fiber drafting, heating, cooling, and winding. However, in actual production, voltage fluctuations in the power grid are a common problem, often referred to as voltage spikes. Voltage spikes cause instability in the voltage of the texturing machine's motor units, affecting the normal operation of the equipment, potentially leading to equipment failure, reduced production efficiency, and increased production costs.

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

[0004] In the process of implementing the embodiments of the present invention, the inventors discovered that the prior art has at least the following problems or defects: the existing anti-voltage fluctuation measures of the texturing machine cannot effectively cope with the complex voltage fluctuation situation when multiple motor units work together, and lacks a comprehensive analysis of the motor unit operation sequence and voltage fluctuation curve, resulting in inaccurate voltage compensation and inability to effectively ensure the stable operation of the texturing machine. Summary of the Invention

[0005] This invention provides a method and system for preventing electrical sloshing in a texturing machine.

[0006] In a first aspect of the present invention, a method for preventing electrical slippage in a texturing machine is provided, comprising:

[0007] Obtain the texturing motor units and their operating sequence for each working mode of the texturing machine;

[0008] The voltage signals under each working mode are monitored in real time, and the voltage of each texturing motor group is sampled by sliding window to obtain the voltage fluctuation curves of each texturing motor group in time sequence.

[0009] Select the texturing motor sets that operate in a fixed order in each working mode, and arrange the voltage data of the texturing motor sets that operate in a fixed order according to the operating order to form the voltage fluctuation curve of the texturing motor sets in each working mode.

[0010] From the voltage fluctuation curve of the texturing motor group in each working mode, identify the adjacent texturing motor groups whose voltage difference between adjacent time windows is greater than a preset threshold, and take the texturing motor group with the lower voltage among the adjacent texturing motor groups as the unit to be stabilized.

[0011] The backup power units in and / or outside the working mode are used to perform voltage compensation on the unit to be stabilized, and the compensated spring-loaded generator units are connected in parallel.

[0012] Based on the compensated parallel combination of the springing motors and the operating sequence of the springing motors, the final operating sequence of the springing motors in the working mode is obtained to realize the anti-power fluctuation control method.

[0013] Furthermore, the texturing motor unit operating in a fixed sequence refers to a texturing motor unit that operates in series or in parallel according to a fixed sequence based on the process flow set in the working mode.

[0014] Furthermore, the preset threshold is specifically half of the maximum value of the working voltage fluctuation of the texturing machine.

[0015] Furthermore, the step of performing sliding window sampling on the voltage of each texturing motor unit to obtain the voltage fluctuation curves of each texturing motor unit arranged in chronological order for each time window specifically includes:

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

[0017] Based on the average voltage value of each window, the voltage fluctuation curves of each time window of each loading motor unit are obtained in chronological order.

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

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

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

[0021] Find the backup power units and their corresponding voltage fluctuation curves within the current operating mode. If there are no available backup power units within the current operating mode, find the backup power units outside the current operating mode and then exclude the backup power units whose voltage fluctuation curves exceed the length of the unit to be stabilized.

[0022] Align the endpoints of the voltage fluctuation curves of the remaining standby power units with the voltage fluctuation curves of the units to be stabilized, and integrate them sequentially according to time windows to obtain the integrated voltage fluctuation curves.

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

[0024] The corresponding integrated voltage fluctuation curve does not exceed the limiting threshold.

[0025] The absolute value of the voltage difference between the corresponding integrated voltage fluctuation curve and the adjacent time window voltage of the adjacent loading motor unit does not exceed the preset threshold.

[0026] If not, find the integrated voltage fluctuation curve and the corresponding backup power unit from each integrated voltage fluctuation curve that meets the requirement of not exceeding the limit threshold and that the voltage difference between the adjacent time window and the adjacent spring-loaded motor unit is less than 0 and the absolute value exceeds the preset threshold.

[0027] Determine whether there is a backup power unit in the corresponding backup power unit that can complete voltage compensation by adjusting the output power. If so, connect the corresponding backup power unit and the unit to be stabilized in parallel as a compensated spring-loaded generator unit.

[0028] If not, the integrated voltage fluctuation curve is used as the voltage fluctuation curve of the unit to be stabilized, and the process of finding the remaining backup power units, integrating and judging is continued 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 loading motor unit is less than the preset threshold. All the corresponding backup power units obtained are connected in parallel with the unit to be stabilized as the compensated loading motor units to realize the anti-power fluctuation control method.

[0029] Furthermore, the process of obtaining the final operating sequence of the texturing motors in the working mode based on the compensated parallel combination of the texturing motors and the operating sequence of the texturing motors specifically includes:

[0030] The voltage fluctuation curve of the texturing motor group after the working mode is obtained based on the parallel combination of the texturing motor group in the working mode and the operating sequence of the texturing motor group.

[0031] If there are unused backup power units in the working mode, the voltage fluctuation curves of the unused backup power units and the updated loading motor units in the working mode are spliced ​​together. It is then determined whether there are adjacent loading motor units in the spliced ​​loading motor unit voltage fluctuation curve where the voltage difference between adjacent time windows is greater than a preset threshold. If so, the process of finding backup power units, integrating and judging is repeated to obtain a parallel combination of loading motor units. The spliced ​​loading motor unit voltage fluctuation curve is then updated based on the parallel combination of loading motor units to obtain the overall loading motor unit voltage fluctuation curve in the working mode. If not, the spliced ​​loading motor unit voltage fluctuation curve is directly used as the overall loading motor unit voltage fluctuation curve in the working mode.

[0032] If there are no unused backup power units in the working mode, the updated brushing generator voltage fluctuation curve will be directly used as the overall brushing generator voltage fluctuation curve for the working mode.

[0033] Determine whether the voltage data of the two endpoints of the overall voltage fluctuation curve of the motor unit in the working mode exceeds the preset threshold. If it does, find a backup power unit that meets the conditions from the backup power units inside and outside the working mode. The conditions are that the voltage data of the found backup power unit and the voltage data of the adjacent time window of the endpoint that exceeds the voltage threshold do not exceed the preset threshold, and the voltage data of the other end does not exceed the preset threshold.

[0034] If no suitable backup power unit can be found, then find the backup power unit with the smallest voltage difference between the time window adjacent to the endpoint that exceeds the preset threshold and whose output power is adjustable, and adjust the output power to make the backup power unit meet the above conditions.

[0035] The voltage fluctuation curve of the identified backup power unit is spliced ​​with one end of the voltage fluctuation curve of the overall generator set in the corresponding working mode to obtain the final voltage fluctuation curve of the generator set in the working mode.

[0036] The operating sequence of the final loading motor unit in the working mode is obtained based on the voltage fluctuation curve of the final loading motor unit in the working mode, so as to realize the anti-power fluctuation control method.

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

[0038] Voltage monitoring unit, unit for acquiring voltage-stabilized units, compensation unit, and operating sequence acquisition unit;

[0039] The voltage monitoring unit is used to acquire the texturing motor group and the operating sequence of the texturing motor group included in each working mode of the texturing machine, monitor the voltage signal 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 curve of each time window of each texturing motor group arranged in time sequence.

[0040] The unit for acquiring the voltage-stabilized unit is used to select the texturing motor units that operate in a fixed order in each working mode, arrange the voltage data of the texturing motor units that operate in a fixed order according to the operating order, form the voltage fluctuation curve of the texturing motor units in each working mode, and find the adjacent texturing motor units whose voltage difference between adjacent time windows is greater than a preset threshold from the voltage fluctuation curve of the texturing motor units in each working mode as the voltage-stabilized unit.

[0041] The compensation unit is used to perform voltage compensation on the unit to be stabilized using a backup power unit inside and / or outside the working mode, and then connect the compensated spring-loaded motor units in parallel.

[0042] The operation sequence acquisition unit obtains the final operation sequence of the springing motor group based on the compensated parallel combination of the springing motor group and the operation sequence of the springing motor group, so as to realize the anti-power fluctuation control method.

[0043] In a third aspect of the invention, a texturing machine with anti-power-slip function is provided. The texturing machine includes a control center that stores the final operating sequence of the texturing motor group in the working mode. The final operating sequence of the texturing motor group in the working mode is obtained by executing the anti-power-slip control method for the texturing machine described in any one of the first aspects.

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

[0045] (1) This invention monitors the voltage signals under 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 chronological order. This can accurately identify the texturing motor group with large voltage fluctuations that needs to be stabilized. At the same time, when acquiring the texturing motor group and the order of operation of the texturing motor group in each working mode of the texturing machine, it clarifies which motor groups participate in the work and their operating order under different working conditions, providing basic data for subsequent voltage monitoring and compensation, and ensuring that the relevant motor groups can be accurately processed when there are voltage fluctuations. It can be seen that it has conducted a comprehensive analysis of the motor group operating order and voltage fluctuation curve, which can ensure that the voltage compensation is accurate enough and effectively ensure the stable operation of the texturing machine.

[0046] (2) This invention utilizes backup power units inside and outside the working mode for voltage compensation, and combines it with operation sequence optimization to achieve precise 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 operation sequence in the working mode based on the parallel combination of the compensated texturing motor units and the operation sequence of the texturing motor units, and ensures the stable operation of the texturing machine under voltage fluctuation by optimizing the operation sequence and parallel combination of the motor units; after considering voltage compensation, each motor unit operates according to the new sequence to achieve the best operating effect;

[0047] (3) This invention can also flexibly adjust the operating sequence and parallel combination of the texturing generator sets according to different working modes and voltage fluctuations. This dynamic adjustment mechanism can maximize the use of the voltage compensation capability of the backup power unit and avoid equipment shutdown and production interruption caused by voltage fluctuations. At the same time, through strict condition judgment and optimization algorithm, it ensures that the compensated voltage fluctuation curve meets the preset threshold requirements, which can further enhance the adaptability and reliability of the texturing machine in complex power grid environments.

[0051] Figure 3 A schematic diagram of the structure of an electronic device according to an embodiment of the present invention is shown. Detailed Implementation

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

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

[0054] It should be noted that the number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0055] The following is for reference. Figure 1 , Figure 1 This is a schematic flowchart illustrating an anti-sloshing control method for a texturing machine according to an embodiment of the present invention. Figure 1 As shown, an anti-sloshing control method for a texturing machine includes:

[0056] S1 obtains the texturing motor group and the running sequence of the texturing motor group 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 texturing motor group to obtain the voltage fluctuation curve of each texturing motor group in time sequence.

[0058] S3 selects the texturing motor groups that operate in a fixed order in each working mode, and arranges the voltage data of the texturing motor groups that operate in a fixed order according to the operating order to form the voltage fluctuation curve of the texturing motor groups in each working mode.

[0059] S4 identifies adjacent texturing motor groups whose voltage difference between adjacent time windows is greater than a preset threshold from the voltage fluctuation curve of the texturing motor group in each working mode, and identifies the texturing motor group with the lower voltage among the adjacent texturing motor groups as the unit to be stabilized.

[0060] S5 uses backup power units inside and / or outside the working mode, and performs voltage compensation on the unit to be stabilized to obtain a compensated spring-loaded generator set in parallel combination;

[0061] S6 obtains the final operating sequence of the springing motors in the working mode based on the compensated parallel combination of the springing motors and the operating sequence of the springing motors, so as to realize the anti-power fluctuation control method.

[0062] It should be noted that obtaining information on the texturing motor units and their operating sequence for each working mode of the texturing machine is primarily to clarify which motor units participate in the work under different working conditions and their operating order. A texturing motor unit refers to the collection of motors in the texturing machine used to drive different process stages, such as the drawing motor unit and the heating motor unit. These motor units work collaboratively according to a specific process flow. The operating sequence refers to the order in which these motor units start and run in each working mode. For example, in preheating mode, the heating motor unit may start first, followed by the drawing motor unit. Obtaining this information provides the foundational data for subsequent voltage monitoring and compensation, ensuring accurate handling of the relevant motor units during voltage fluctuations.

[0063] Specifically, real-time monitoring of voltage signals under various operating modes refers to continuously acquiring voltage data from the texturing generator set using devices such as voltage sensors. Sliding window sampling is a signal processing method that segments the voltage data to obtain voltage fluctuation curves arranged in chronological order for each time window. Here, "sliding window" refers to moving the sampling window of a fixed length across 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 per second, and the preset window length can be set to 5ms, meaning each sampling window covers a 5-millisecond time period. In this way, continuous voltage signals can be converted into discrete voltage data points, and the average voltage within each window can be calculated, thus obtaining the voltage fluctuation curves for each texturing generator set. These curves can intuitively reflect the voltage changes over time, providing a basis for subsequent voltage difference calculations and the determination of the unit to be stabilized.

[0064] Preferably, the determination of the unit to be stabilized can be made by identifying adjacent texturing motor units whose voltage difference between adjacent time windows exceeds a preset threshold from the voltage fluctuation curves of the texturing motor units in each operating mode. The preset threshold can be set according to the actual operating voltage range and process requirements of the texturing machine, for example, it can be set to 1 / 2 of the maximum voltage fluctuation value of the texturing machine. In this way, when the voltage difference between adjacent time windows exceeds this threshold, the voltage fluctuation of the motor unit can be considered large, and voltage stabilization is required. Using texturing motor units with lower voltage as the unit to be stabilized is to prioritize compensation for motor units with insufficient voltage, ensuring their normal operation. Furthermore, during voltage compensation, backup power units within and / or outside the operating mode can be used. Backup power units refer to power supply equipment that does not participate in the main operation in the normal operating mode but can provide additional voltage support during voltage fluctuations. By connecting backup power units in parallel with the unit to be stabilized and adjusting the operating sequence according to the compensated voltage fluctuation curve, effective voltage compensation for the texturing motor units can be achieved, thereby improving the operational stability of the texturing machine under voltage fluctuation conditions.

[0065] In some embodiments, the texturing motor unit operating in a fixed sequence refers to a texturing motor unit that operates in series or in parallel according to a fixed sequence based on the process flow set in the working mode.

[0066] It should be noted that fixed-sequence texturing motor sets refer to motor sets that start and run sequentially according to a predetermined process flow under specific operating modes of the texturing machine. This operating mode ensures the coordinated work of each process stage of the texturing machine. For example, in processes such as drafting, heating, and winding, the motor sets need to start and run in a certain order to ensure the continuity and quality of fiber processing. Fixed-sequence texturing motor sets can operate in series, where the output of one motor set serves as the input of the next; or they can operate in parallel, where multiple motor sets work simultaneously to complete a certain process stage. This method ensures stable operation of the texturing machine under different operating modes and provides a clear target for monitoring and compensating for voltage fluctuations.

[0067] Specifically, texturing motor sets operating in a fixed sequence have different operating modes under different working conditions. For example, in preheating mode, the heating motor set may start first, followed by the drafting motor set; this sequential starting method is considered series operation. In normal production mode, multiple motor sets may start simultaneously and work together, which is considered parallel operation. In series operation, the starting sequence and running time of the motor sets are key parameters; for example, the heating motor set needs to start 10 minutes in advance to reach the preset temperature, followed by the drafting motor set. In parallel operation, power distribution and coordinated control of each motor set are crucial; for example, multiple motor sets need to synchronously adjust their speeds to ensure fiber tension. The choice of these operating modes depends on the specific process requirements and production flow of the texturing machine. By clearly defining the operating sequence and method of the motor sets, voltage fluctuations can be better monitored and compensated for accordingly.

[0068] Preferably, during implementation, the operating parameters of the texturing motor units operating in a fixed sequence can be further refined according to the specific process flow and production requirements of the texturing machine. For example, in series operation, a start-up delay time for each motor unit can be set to ensure that the next motor unit starts only after the previous motor unit has reached a stable operating state. In parallel operation, the power distribution ratio of each motor unit can be set, and the current and voltage of each motor unit can be monitored in real time by sensors to ensure power balance among the motor units 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, voltage fluctuations under different operating conditions can be simulated, thus providing a more accurate basis for voltage compensation. These refined measures can further improve the texturing machine's operational stability and production efficiency under voltage fluctuation conditions.

[0070] In some embodiments, the preset threshold is specifically half of the maximum value of the working voltage fluctuation of the texturing machine.

[0071] It should be noted that the preset threshold is a key parameter used to determine whether the voltage fluctuation of the texturing machine exceeds the normal range. Specifically, the preset threshold is set to half of the maximum voltage fluctuation of the texturing machine, 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 voltage stabilization is required. This setting considers both the operational stability of the texturing machine and the timeliness and effectiveness of voltage compensation, ensuring that measures can be taken quickly when voltage fluctuations are large, thus guaranteeing the normal operation of the equipment.

[0072] Specifically, the maximum 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 unit is too large and compensation is required. This setting can effectively distinguish between normal and abnormal voltage fluctuations, providing a clear basis for subsequent voltage compensation.

[0073] Preferably, in practical applications, the preset threshold setting can be further optimized according to the specific model and process requirements of the texturing machine. For example, for some texturing machines with high voltage stability requirements, the preset threshold can be set smaller to improve the system's sensitivity. Simultaneously, a voltage fluctuation model can be established, inputting parameters such as the texturing machine's rated voltage and the maximum allowable voltage fluctuation range, to simulate voltage fluctuations under different operating modes, thereby determining the preset threshold more accurately. Furthermore, during data processing, voltage sampling data can be filtered to reduce the impact of noise on voltage fluctuation judgment. Through these refined measures, the system's stability and reliability can be further improved, ensuring the texturing machine operates stably under various voltage fluctuation conditions.

[0074] In some embodiments, the step of sampling the voltage of each texturing motor unit through a sliding window to obtain the voltage fluctuation curves of each texturing motor unit arranged in chronological order for each time window 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 average voltage value of each window.

[0076] Based on the average voltage value of each window, the voltage fluctuation curves of each time window of each loading motor unit are obtained in chronological order.

[0077] It should be noted that sliding window sampling of the voltage of each texturing generator unit is performed to obtain voltage fluctuation curves arranged in chronological order for each time window. Sliding window sampling is a signal processing technique that moves a fixed-length window across the time series of the voltage signal and samples and processes the voltage data within the window to obtain the voltage fluctuation. This method can effectively capture instantaneous voltage changes and convert them into discrete data points, facilitating subsequent analysis and processing. The preset frequency refers to the sampling frequency, i.e., the number of samples per unit time, while the preset window length refers to the size of the sliding window, i.e., the time range covered by each sampling. The voltage fluctuation curves obtained through sliding window sampling can intuitively reflect the voltage changes of the texturing generator unit within different time windows, providing data support for subsequent voltage difference calculations and the determination of the unit to be stabilized.

[0078] Specifically, the preset frequency refers to the voltage sampling frequency, for example, it can be set to 200Hz, meaning 200 samples per second. This means that the system will sample the voltage signal 200 times per second, acquiring 200 voltage data points. The preset window length refers to the size of the sliding window, for example, it can be set to 5ms, meaning each sampling window covers a time period of 5 milliseconds. Within this window, the system will calculate the average voltage value of all sampling points within the window, thus obtaining the average voltage value within that time window. In this way, continuous voltage signals can be 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 calculations and the determination of the generator unit to be stabilized. For example, if the average voltage suddenly drops within a certain time window, this indicates that the voltage of the generator unit has fluctuated, requiring further analysis and processing.

[0079] Preferably, during implementation, the parameter settings of the sliding window sampling can be further optimized according to 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, such as setting it to 300Hz or higher, to more accurately capture instantaneous voltage changes. Simultaneously, the length of the sliding window can be adjusted according to the process requirements of the texturing machine and the voltage fluctuation range, for example, setting it to 3ms or shorter, to respond to voltage changes more quickly.

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

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

[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, thus reflecting voltage fluctuations more precisely. In this invention, the preset frequency is specifically set to 200Hz, i.e., 200 samples per second. This frequency setting was determined after comprehensively considering the voltage fluctuation characteristics and data processing capabilities of the texturing machine, aiming to ensure data accuracy while avoiding excessive data volume from burdening the system's processing capacity.

[0083] Specifically, the sampling frequency is a crucial parameter in the sliding window sampling process. For example, when the sampling frequency is set to 200Hz, it means that the system will sample the voltage signal 200 times per second, acquiring 200 voltage data points. These data points can be used to calculate the average voltage within each sliding window, thereby generating a voltage fluctuation curve arranged in chronological order. The selection of the sampling frequency needs to be determined based on the actual operating conditions of the texturing machine and the characteristics of voltage fluctuations. If the voltage fluctuations of the texturing machine are relatively drastic, a higher sampling frequency is needed to capture these rapid changes; while if the voltage fluctuations are relatively stable, the sampling frequency can be appropriately reduced to decrease 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 300Hz or higher to more accurately capture instantaneous voltage changes. Simultaneously, the most suitable combination of sampling frequency and sliding window length can be determined through experiments and data analysis. For instance, by comparing voltage fluctuation curves generated at different sampling frequencies, the sampling frequency that most accurately reflects the actual voltage fluctuation 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.

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

[0086] It should be noted that the preset window length refers to the time range covered by each sample 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 this invention, the preset window length is specifically set to 5ms. This setting aims to balance the smoothness of the data and the ability to respond to rapid voltage changes. A shorter window length can reflect instantaneous voltage changes more quickly, but may introduce more noise; while 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 trade-off 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. For example, when the window length is set to 5ms, each sampling calculates the average voltage of all sampling points within those 5ms. This average represents the average voltage level within that time window, thus forming a voltage fluctuation curve arranged in chronological order. The choice of window length needs to be determined based on the actual operating conditions of the texturing machine and the characteristics of voltage fluctuations. If voltage fluctuations are relatively drastic and frequent, a shorter window length, such as 3ms, may be more suitable to capture instantaneous changes more quickly; while if voltage fluctuations are relatively stable, a longer window length, such as 10ms, can make the curve smoother and reduce the impact of noise. In addition, 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 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 less to improve the response capability to rapid changes. Simultaneously, the most suitable window length can be determined through experiments and data analysis. For instance, by comparing voltage fluctuation curves generated under different window lengths, the window length that most accurately reflects the actual voltage fluctuation 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, the voltage compensation of the unit to be stabilized is performed to obtain a parallel combination of the compensated brushing motor units, specifically including:

[0090] Find the backup power units and their corresponding voltage fluctuation curves within the current operating mode. If there are no available backup power units within the current operating mode, find the backup power units outside the current operating mode and then exclude the backup power units whose voltage fluctuation curves exceed the length of the unit to be stabilized.

[0091] Align the endpoints of the voltage fluctuation curves of the remaining standby power units with the voltage fluctuation curves of the units to be stabilized, and integrate them sequentially according to time windows to obtain the integrated voltage fluctuation curves.

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

[0093] The corresponding integrated voltage fluctuation curve does not exceed the limiting 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 loading motor unit does not exceed the preset threshold.

[0095] If not, find the integrated voltage fluctuation curve and the corresponding backup power unit from each integrated voltage fluctuation curve that meets the requirement of not exceeding the limit threshold and that the voltage difference between the adjacent time window and the adjacent spring-loaded motor unit is less than 0 and the absolute value exceeds the preset threshold.

[0096] Determine whether there is a backup power unit in the corresponding backup power unit that can complete voltage compensation by adjusting the output power. If so, connect the corresponding backup power unit and the unit to be stabilized in parallel as a compensated spring-loaded generator unit.

[0097] If not, the integrated voltage fluctuation curve is used as the voltage fluctuation curve of the unit to be stabilized, and the process of finding the remaining backup power units, integrating and judging is continued 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 loading motor unit is less than the preset threshold. All the corresponding backup power units obtained are connected in parallel with the unit to be stabilized as the compensated loading motor units to realize the anti-power fluctuation control method.

[0098] It should be noted that voltage compensation for the voltage-stabilized unit is the core of the anti-voltage fluctuation control method. This process involves multiple steps, including screening of backup power units, integration of voltage fluctuation curves, and condition judgment. Backup power units are power supply devices that are in standby mode during normal operation but can provide additional voltage support during voltage fluctuations. By connecting backup power units in parallel with the unit to be stabilized, and selecting appropriate backup power units based on specific conditions, insufficient voltage can be effectively compensated, ensuring the stable operation of the texturing machine. This process not only requires consideration of voltage fluctuation curve matching but also ensures that the compensated voltage fluctuation does not exceed the limiting threshold, thereby guaranteeing the normal operation of the texturing machine under voltage fluctuation conditions.

[0099] Specifically, the process of voltage compensation for the voltage-stabilized unit includes the following key steps. First, it is necessary to identify the backup power supply unit within the current operating mode and obtain its corresponding voltage fluctuation curve. If no backup power supply unit is available within the current operating mode, it is necessary to search for backup power supply units outside the operating mode. When screening backup power supply units, it is necessary to exclude those whose voltage fluctuation curve length exceeds that of the voltage-stabilized unit, as such units may not be able to effectively match the voltage fluctuation characteristics of the voltage-stabilized unit. Next, the voltage fluctuation curves of the remaining backup power supply units are aligned one by one with the endpoints of the voltage fluctuation curve of the voltage-stabilized unit, and integrated sequentially according to time windows to obtain the integrated voltage fluctuation curves. The integrated voltage fluctuation curves need to meet two conditions: first, they do not exceed the limiting threshold; second, the absolute value of the voltage difference with the adjacent time window of the adjacent voltage-stabilized unit does not exceed a preset threshold. If there is a backup power supply unit that meets these conditions, it is connected in parallel with the voltage-stabilized unit to complete the voltage compensation. If no backup power unit fully meets the requirements, further screening and adjustments are needed. For example, select a backup power unit with adjustable output power and adjust its output power to meet the compensation requirements.

[0100] Preferably, during voltage compensation, some operational steps can be further refined to improve the accuracy and reliability of the compensation. For example, when selecting backup power units, priority can be given based on their power capacity and voltage stability, prioritizing backup power units with larger power and stable voltage. When integrating voltage fluctuation curves, interpolation algorithms can be used to handle the alignment of curve endpoints, ensuring that the integrated curve is smoother and more accurate. Furthermore, a voltage compensation model can be established, with input parameters including the voltage fluctuation curves of the unit to be stabilized, the voltage fluctuation curves of the backup power units, limiting thresholds, and preset thresholds. Through model calculation and optimization, the optimal backup power units can be selected for parallel combination. During data processing, the integrated voltage fluctuation curves can be smoothed to reduce abrupt changes 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 sequence of the texturing motors in the working mode based on the compensated parallel combination of the texturing motors and the operating sequence of the texturing motors specifically includes:

[0102] The voltage fluctuation curve of the texturing motor group after the working mode is obtained based on the parallel combination of the texturing motor group in the working mode and the operating sequence of the texturing motor group.

[0103] If there are unused backup power units in the working mode, the voltage fluctuation curves of the unused backup power units and the updated loading motor units in the working mode are spliced ​​together. It is then determined whether there are adjacent loading motor units in the spliced ​​loading motor unit voltage fluctuation curve where the voltage difference between adjacent time windows is greater than a preset threshold. If so, the process of finding backup power units, integrating and judging is repeated to obtain a parallel combination of loading motor units. The spliced ​​loading motor unit voltage fluctuation curve is then updated based on the parallel combination of loading motor units to obtain the overall loading motor unit voltage fluctuation curve in the working mode. If not, the spliced ​​loading motor unit voltage fluctuation curve is directly used as the overall loading motor unit voltage fluctuation curve in the working mode.

[0104] If there are no unused backup power units in the working mode, the updated brushing generator voltage fluctuation curve will be directly used as the overall brushing generator voltage fluctuation curve for the working mode.

[0105] Determine whether the voltage data of the two endpoints of the overall voltage fluctuation curve of the motor unit in the working mode exceeds the preset threshold. If it does, find a backup power unit that meets the conditions from the backup power units inside and outside the working mode. The conditions are that the voltage data of the found backup power unit and the voltage data of the adjacent time window of the endpoint that exceeds the voltage threshold do not exceed the preset threshold, and the voltage data of the other end does not exceed the preset threshold.

[0106] If no suitable backup power unit can be found, then find the backup power unit with the smallest voltage difference between the time window adjacent to the endpoint that exceeds the preset threshold and whose output power is adjustable, and adjust the output power to make the backup power unit meet the above conditions.

[0107] The voltage fluctuation curve of the identified backup power unit is spliced ​​with one end of the voltage fluctuation curve of the overall generator set in the corresponding working mode to obtain the final voltage fluctuation curve of the generator set in the working mode.

[0108] The operating sequence of the final loading motor unit in the working mode is obtained based on the voltage fluctuation curve of the final loading motor unit in the working mode, so as to realize the anti-power fluctuation control method.

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

[0110] Specifically, determining the final operating sequence of the texturing generator sets in the operating mode involves multiple steps. First, based on the compensated parallel combination of the texturing generator sets and the original operating sequence, the updated voltage fluctuation curve of the texturing generator sets in the operating mode is obtained. The purpose of this step is to evaluate the current voltage stability through the voltage fluctuation curve of the parallel combination of generator sets. If there are unused backup power units within the operating mode, these backup power units need to be spliced ​​with the updated voltage fluctuation curve, and it needs to be determined whether there is a situation where the voltage difference between adjacent time windows is greater than a preset threshold. If so, the screening, integration, and judgment operations of backup power units need to be repeated to further optimize the parallel combination. Finally, through these steps, the overall voltage fluctuation curve of the texturing generator sets in the operating mode is obtained, and the final operating sequence of the texturing generator sets is determined based on this curve. This process needs to consider multiple parameters, including the splicing point of the voltage fluctuation curve, the voltage difference between adjacent time windows, and the output power of the backup power units.

[0111] Preferably, during implementation, some operational steps can be further refined to improve the stability and reliability of the system. For example, when splicing voltage fluctuation curves, a smooth transition algorithm can be used to ensure the continuity and smoothness of the curves at the splicing points, reducing voltage spikes caused by splicing. When selecting backup power units, priority can be given based on their output power adjustability and voltage stability, prioritizing backup power units with larger power and stable voltage. Furthermore, an operation sequence optimization model can be established, with input parameters including the compensated parallel combination of the replenishing generator sets, the voltage fluctuation curves of unused backup power units, and preset thresholds. Through model calculation and optimization, the optimal operating sequence of the replenishing generator sets can be determined. During data processing, the updated voltage fluctuation curves can be filtered to reduce the impact of noise on the voltage fluctuation curves, thereby further improving the monitoring accuracy and reliability of the system.

[0112] The above embodiments of the present invention have the following beneficial effects: This anti-voltage fluctuation control method can monitor voltage fluctuations in each operating mode of the texturing machine in real time, accurately capture abnormal voltage changes through sliding window sampling technology, and automatically identify units requiring voltage stabilization based on preset thresholds. By intelligently matching backup power units for dynamic voltage compensation, it can ensure that the texturing machine units can maintain stable operation during voltage fluctuations, avoiding equipment shutdowns or production interruptions caused by voltage instability. Simultaneously, this method can optimize the unit operating sequence, enabling the entire system to continue operating according to the optimal process after voltage compensation, thereby improving production efficiency.

[0113] Furthermore, this method can flexibly utilize backup power resources both inside and outside the operating mode, ensuring the effectiveness of voltage compensation through multiple rounds of screening and power adjustment. Even in the event of extreme voltage fluctuations, the system can still maintain stable power supply by dynamically adjusting the output power of the backup units. The resulting optimized operating sequence ensures the continuous and reliable operation of the texturing machine under complex conditions, reduces production losses caused by voltage fluctuations, and improves the overall anti-interference capability of the equipment.
