Description

Technical Field

[0001] This application relates to the technical field of spinning, and in particular to a method and system for managing yarn breakage based on online monitoring. Background Technology

[0002] The spinning process involves drafting, twisting, and winding roving into fine yarn with a specific linear density that meets national quality standards. This yarn is then used for twisting, weaving, or knitting. The process is costly and poses significant challenges to yarn mill management and quality control. Therefore, the cost, quality, and output of the spinning process directly determine the economic benefits of a yarn mill.

[0003] In the spinning process, yarn breakage is a major factor restricting the quality and output of yarn produced by the spinning machine. If yarn breakage is not addressed for a long time, it will directly affect the output of yarn and the production efficiency of the equipment, and in severe cases, it will cause fabric defects and damage to textile machinery parts. Therefore, when yarn breaks, it is crucial to quickly identify the cause of the breakage and locate the corresponding position so that the machine operator can repair the breakage as soon as possible.

[0004] Related technologies, such as the patent with publication number CN110565220A, disclose a real-time correlation and location method for yarn breakage factors based on online monitoring. This method analyzes breakage factors by monitoring parameter data of the spinning equipment and using data correlation analysis to improve the efficiency of factor determination. However, in these related technologies, after the breakage factors are analyzed, repair work is required from a mechanic. Machine operators typically only perform yarn splicing, and due to limitations in their own capabilities, they cannot perform repairs quickly and accurately, leading to repeated yarn breaks. Summary of the Invention

[0005] To address the problem of repeated yarn breakage caused by the limited capabilities of yarn operators and mechanics, who are unable to perform repairs quickly and accurately, this application provides a method and system for managing yarn breakage based on online monitoring, employing the following technical solution:

[0006] A method for managing yarn breakage based on online monitoring, applied in a spinning machine, wherein a movable operation screen is installed on one side of the spinning machine, and the method includes the following steps:

[0007] Real-time online monitoring of various parameter data of the spinning equipment;

[0008] Real-time monitoring of yarn breakage; when yarn breaks, record the breakage location and the parameters of the spinning equipment.

[0009] Data correlation analysis is used to analyze the data of spinning equipment, and output the breakage factors, breakage handling suggestions and corresponding operation videos. The breakage handling suggestions include those that can be handled by ordinary permissions and those that can be handled by advanced permissions.

[0010] The movable operation screen is controlled to move to one of the severed positions, and the movable operation screen is controlled to display all severed positions, the severed factors of the current severed position, severed handling suggestions, and operation video.

[0011] By adopting the above technical solution, in related technologies, since the machine operator is not a professional maintenance personnel and due to limitations in their abilities, they cannot accurately locate the cause of yarn breakage and perform correct repairs. Therefore, the machine operator generally only repairs broken yarn and is strictly prohibited from tampering with the machine. When equipment problems are discovered, they need to be reported to the mechanic for handling. However, during the process from the machine operator repairing the broken yarn to the mechanic handling the breakage factor, repeated breakages are prone to occur. Therefore, this application monitors various parameter data of the spinning equipment in real time online. When a yarn breakage occurs, it records the breakage location and the parameter data of the spinning equipment, and then uses data correlation analysis methods to analyze the data of the spinning equipment. Finally, the system outputs the breakage location, breakage factor, breakage handling suggestions, and corresponding operation video. The breakage handling suggestions include those that can be handled with normal permissions and those that can be handled with advanced permissions. Then, the system moves to the breakage location via a movable operation screen and outputs all breakage locations, the breakage factor at the current breakage location, the breakage handling suggestions, and the corresponding operation video. This allows machine operators and mechanics to handle common breakage factors based on the above information and to handle equipment faults within their respective permission ranges. On the one hand, it facilitates machine operators in locating breakages; on the other hand, machine operators can handle simple breakage factors after reconnecting the broken parts. On the other hand, mechanics can perform repairs more quickly and accurately, avoiding the occurrence of repeated breakages.

[0012] Optionally, the step of analyzing the data of the spinning equipment using data correlation analysis methods and outputting breakage factors, breakage handling suggestions, and corresponding operation videos specifically includes the following sub-steps:

[0013] The factors contributing to yarn breakage were analyzed using data correlation analysis.

[0014] Based on the factors causing yarn breakage, the system searches a pre-set database for breakage handling suggestions and corresponding operation videos. The breakage handling suggestions include those that can be handled by ordinary users and those that can be handled by advanced users.

[0015] Output the factors causing the head breakage, suggestions for handling the breakage, and corresponding operation videos.

[0016] By adopting the above technical solution, this application pre-sets a database. By pre-entering breakage handling suggestions and corresponding operation videos for each yarn breakage factor, after obtaining the yarn breakage factors through data correlation analysis, the corresponding breakage handling suggestions and corresponding operation videos are found in the pre-set database and then output.

[0017] Optionally, the method further includes:

[0018] When the decapitation handling suggestion includes at least one processing step, a priority processing step is determined and output as the current processing step.

[0019] Receive user feedback on the processing result of the current processing step, and determine the subsequent processing steps from the processing item tree based on the processing result, until there are no subsequent processing steps for the current processing step in the processing item tree.

[0020] By adopting the above technical solution, after locating the cause of the breakage, when the breakage handling suggestion includes multiple handling steps, this application determines a priority handling step, then receives the handling result feedback from the user, and determines the subsequent handling steps from the handling item tree, so that the mechanic can check and repair in sequence according to the handling steps, thereby improving the mechanic's ability to handle complex faults.

[0021] Optionally, the process of obtaining the processing item tree includes:

[0022] Based on the working principle of the spinning equipment, the fault correlation between various modules of the spinning equipment is obtained;

[0023] A processing project tree is generated based on fault correlations.

[0024] By adopting the above technical solution, based on the working principle of the spinning equipment, the fault correlation between various modules of the spinning equipment is obtained, and a processing project tree is generated based on the fault correlation, thereby locating the priority between each processing step and improving the repair efficiency of machine repairmen.

[0025] Optionally, the method further includes:

[0026] Record the cumulative number of repeated decapitations detected at the current decapitation location within a specified time period;

[0027] When the number of repeated decapitations exceeds the first threshold, the current decapitation position is marked.

[0028] When the number of repeated breakages exceeds the second threshold, the spindle operation corresponding to the current breakage position is paused.

[0029] By adopting the above technical solution, when the number of repeated breakages exceeds the first threshold, the breakage location is marked for more in-depth maintenance. When the number of breakages exceeds the first threshold, it is necessary to suspend the corresponding spindle operation to prevent equipment damage.

[0030] Optionally, the method further includes:

[0031] The doffing signal is acquired in real time, and when the doffing signal is received, the movable operation screen is controlled to move to one end of the spinning equipment.

[0032] By adopting the above technical solution, when the doffing signal is received, this application controls the movable operating screen to move to one end of the spinning equipment to prevent the movable operating screen from obstructing the doffing and improve usability.

[0033] Optionally, the movable operating screen is equipped with a camera device, and the method further includes:

[0034] After the movable operating screen is moved to one of the severed head positions, the camera device is controlled to capture and record an image of the current severed head position.

[0035] After receiving feedback from the user that the process is complete, the camera device is controlled to capture and record an image of the current decapitation location.

[0036] By adopting the above technical solution, this application sets up a camera device on a movable operating screen. When the movable operating screen moves to one of the broken-off positions, the camera device is controlled to capture and record the image of the current broken-off position. After obtaining feedback from the user that the processing is completed, the camera device is controlled to capture and record the image of the current broken-off position again. This allows for the capture and fixation of the broken-off position before and after the user's processing, facilitating comparison and determining the processing effect.

[0037] Secondly, this application provides a yarn breakage management system based on online monitoring, comprising the following steps:

[0038] The real-time parameter data detection module is used to monitor various parameter data of the spinning equipment in real time online;

[0039] The parameter data recording module is used to monitor the yarn breakage situation in real time. When the yarn breaks, it records the breakage location and the parameter data of the spinning equipment.

[0040] The output module is used to analyze the data of the spinning equipment using data correlation analysis methods, and output the breakage factors, breakage handling suggestions and corresponding operation videos. The breakage handling suggestions include those that can be handled by ordinary permissions and those that can be handled by advanced permissions.

[0041] The mobile display module is used to control the movable operation screen to move to one of the broken ends, and to control the movable operation screen to display all broken ends, the broken end factors of the current broken end, broken end handling suggestions, and operation video.

[0042] Thirdly, this application provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above-described online monitoring-based yarn breakage management method.

[0043] Fourthly, this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the above-described online monitoring-based yarn breakage management method.

[0044] In summary, this application includes at least one of the following beneficial technical effects:

[0045] This application monitors various parameters of the spinning equipment in real time online. When a yarn breakage occurs, it records the breakage location and the equipment's parameters. Then, it analyzes the equipment data using data correlation analysis and outputs the breakage location, breakage factors, breakage handling suggestions, and corresponding operation videos. The breakage handling suggestions include those that can be handled by ordinary and advanced permissions. The user can then move to the breakage location via a movable operation screen and view all breakage locations, the breakage factors at the current breakage location, breakage handling suggestions, and corresponding operation videos. This allows machine operators and mechanics to handle equipment malfunctions within their respective permissions based on the above information. This facilitates machine operators in locating breakages and allows them to address simple breakage factors after reconnecting the broken yarn. Mechanics can also perform repairs more quickly and accurately, preventing repeated breakages.

[0046] After identifying the cause of the breakage, when the breakage handling suggestion includes multiple handling steps, this application determines a priority handling step, then receives the handling result feedback from the user, and determines the subsequent handling steps from the handling item tree, so that the mechanic can check and repair in sequence according to the handling steps, thereby improving the mechanic's ability to handle complex faults.

[0047] This application uses a camera device mounted on a movable operating screen. When the movable operating screen is moved to one of the severed positions, the camera device is controlled to capture and record an image of the current severed position. After receiving feedback from the user that the processing is complete, the camera device is controlled to capture and record an image of the current severed position again. This allows for the preservation of images of the severed position before and after the user's processing, facilitating comparison and determining the processing effect. Attached Figure Description

[0053] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to any or all possible combinations including one or more of the listed items.

[0054] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0055] In this technology, the machine operator is responsible for repeatedly inspecting and locating broken wires. When a broken wire is found, the wiring is reconnected. If any equipment malfunction is detected, it is reported to the mechanic for repair. However, the machine operator's repeated inspections are inefficient and they cannot accurately pinpoint and address the cause of the broken wire. This results in time-consuming and laborious troubleshooting, and the repairs are often delayed, leading to repeated broken wires.

[0056] This application provides a method for managing yarn breakage based on online monitoring. By monitoring various parameter data of the spinning equipment online, analyzing the parameter data, and then outputting the breakage location, breakage factors, breakage handling suggestions, and corresponding operation videos, the breakage location can be quickly located. This allows machine operators and mechanics to inspect and repair the yarn based on the breakage factors, breakage handling suggestions, and corresponding operation videos at the current breakage location, thereby reducing repeated breakages.

[0057] The concept of this application is described below with reference to specific embodiments.

[0058] Reference Figure 1 , Figure 1 This is an exemplary flowchart of a yarn breakage management method based on online monitoring, as an embodiment of this application.

[0059] A method for managing yarn breakage based on online monitoring includes the following steps:

[0060] S110, real-time online monitoring of various parameter data of the spinning equipment.

[0061] Among them, the fine spinning equipment includes equipment status parameters, equipment operating parameters, process parameters, raw cotton quality parameters, and environmental parameters.

[0062] S120: Real-time monitoring of yarn breakage; when yarn breaks, record the breakage location and the parameters of the spinning equipment.

[0063] Each spindle is equipped with a photoelectric sensor, which uses a single-spindle monitoring system to locate abnormal single-spindles and record the location and number of the broken end. Furthermore, when a break occurs, the system records the parameter data of the spinning equipment to analyze the cause of the break.

[0064] S130. Analyze the data of the spinning equipment using data correlation analysis methods, and output the breakage factors, breakage handling suggestions and corresponding operation videos. The breakage handling suggestions include those that can be handled by ordinary permissions and those that can be handled by advanced permissions.

[0065] The analysis of spinning equipment data using data correlation analysis methods includes setting reasonable process ranges for equipment status, equipment operation, process, raw cotton quality, and environment. Equipment status includes the status of the traveler and ring; equipment operation includes spindle speed; process includes twist; raw cotton quality includes roving strength and evenness; and environment includes temperature and humidity. When a yarn breakage occurs, the breakage location is recorded, along with the equipment status at that location.

[0066] Reference Figure 2 This is another exemplary flowchart of a yarn breakage management method based on online monitoring, according to an embodiment of this application.

[0067] Step S130 further includes the following sub-steps:

[0068] S131. The factors causing yarn breakage were analyzed using data correlation analysis.

[0069] The process involves acquiring relevant raw data from the spinning equipment through an online monitoring system. This raw data includes eight variables: traveler status, ring status, spindle speed, twist, roving strength, evenness, temperature, and humidity. Based on the respective process parameter ranges of these eight variables, the raw data is standardized using an interval-based value operator to obtain standardized variable data. The correlation coefficient between the standardized variable data at time k and the spinning breakage is calculated using the correlation coefficient formula. The correlation degree between the standardized variable data at time k and the spinning breakage is then calculated using the correlation degree formula based on the correlation coefficient. Finally, the correlation coefficients are ranked, and the variable corresponding to the highest correlation degree is identified as the spinning breakage factor.

[0070] S132. Based on the factors causing yarn breakage, search the preset database for breakage handling suggestions and corresponding operation videos.

[0071] This application pre-records breakage handling suggestions and corresponding operation videos for each breakage factor. The breakage handling suggestions include handling steps and handling permissions. For example, when the breakage factor is an abnormal condition of the wire ring, the corresponding handling suggestions include steps such as checking the basic dimensions, surface roughness, magnetism, hardness, and opening tensile deformation of the wire ring, as well as operation steps such as replacing and cleaning the wire ring. Then, the corresponding operation video is output simultaneously. In addition, each handling step is set with handling permissions, including ordinary permission and advanced permission. The machine operator can only operate the ordinary permission handling steps, while the mechanic can operate the ordinary permission and advanced permission handling steps. The specific division is set according to the difficulty of handling and the degree of impact on equipment operation.

[0072] S133 outputs the factors causing the breakage, suggestions for handling the breakage, and corresponding operation videos.

[0073] After obtaining decapitation treatment suggestions and corresponding operation videos based on the factors causing the decapitation, all three will be output.

[0074] S140. Control the movable operation screen to move to one of the broken ends, and control the movable operation screen to display all broken ends, the broken end factors of the current broken end, broken end handling suggestions, and operation video.

[0075] One side of the spinning machine is equipped with a movable control screen. This screen is movable and operable, displaying the breakage location, the factors causing the breakage, breakage handling suggestions, and operational videos. It can also receive signals and move and display information. When a breakage is detected, the movable control screen is moved to one of the breakage locations, allowing the operator to pinpoint the breakage and handle it according to the information displayed on the screen.

[0076] In some optional embodiments, the movable operating screen also displays a video of the disconnection operation.

[0077] Reference Figure 3 , Figure 3 This is another exemplary flowchart of a yarn breakage management method based on online monitoring, as described in this application.

[0078] In some optional embodiments, the method further includes:

[0079] S150: Real-time acquisition of doffing signal; upon receiving the doffing signal, control the movable operation screen to move to one end of the spinning equipment.

[0080] Specifically, a doffing signal is issued in advance when the equipment starts doffing, and then the movable operation screen is moved to one end of the equipment to prevent the movable operation screen from obstructing the doffing, thereby improving usability.

[0081] In some optional embodiments, the movable operating screen is equipped with a camera device, and the method further includes:

[0082] S160. After the movable operating screen is moved to one of the broken-off positions, the camera device is controlled to capture and record an image of the current broken-off position.

[0083] S190. After receiving feedback from the user that the process is complete, control the camera device to take another picture of the current decapitation position and record it.

[0084] The movable operating screen is equipped with a camera device. When the movable operating screen moves to one of the broken ends, it controls the camera device to take an image of the current broken end position and record it. After receiving feedback from the user that the processing is completed, it controls the camera device to take an image of the current broken end position again and record it. This allows for the preservation of images of the broken end position before and after the user's processing, facilitating comparison and determining the processing effect.

[0085] The implementation principle of the yarn breakage management method based on online monitoring in this application embodiment is as follows: The system monitors various parameter data of the spinning equipment in real time. When the photoelectric sensor detects a yarn breakage, the system records the breakage location and the parameter data of the spinning equipment. Then, it analyzes the data of the spinning equipment using a data correlation analysis method, and finally outputs the breakage location, breakage factors, breakage handling suggestions, and corresponding operation videos to a movable operation screen. After receiving all breakage locations, breakage factors, breakage handling suggestions, and corresponding operation videos, the movable operation screen moves to one of the breakage locations. The mobile control panel displays suggested solutions and an operation video for handling the broken section at its current location. The operator can quickly locate the broken section using the panel and proceed to reconnect it. The panel also allows the operator to determine if the suggested solutions require normal access. If so, the operator follows the instructions in the video to inspect and repair the equipment. Similarly, mechanics can use the mobile control panel to perform repairs quickly and accurately, reducing the occurrence of repeated broken sections.

[0086] The above embodiments display all broken ends, the broken end factors at the current broken end, broken end handling suggestions, and operation videos on a movable operation screen, so that machine operators and mechanics can perform inspections and repairs based on the content displayed on the operation screen. In some embodiments, when the broken end handling suggestions include multiple handling steps, a priority handling step is selected.

[0087] Optionally, a method for managing yarn breakage based on online monitoring further includes the following steps:

[0088] S170. When the decapitation handling suggestion includes at least one handling step, determine a priority handling step and output the priority handling step as the current handling step.

[0089] S180. Receive user feedback on the processing result for the current processing step, and determine the subsequent processing steps from the processing item tree based on the processing result, until there are no subsequent processing steps for the current processing step in the processing item tree.

[0090] The process of obtaining the processing project tree involves first identifying the fault relationships between various modules of the spinning equipment based on its working principle, and then generating the processing project tree based on these relationships. These fault relationships include both derivative and logical relationships; a fault in one area can lead to faults in others. Therefore, this application generates the processing project tree based on these relationships and determines subsequent processing steps, enabling mechanics to sequentially inspect and repair according to these steps, thus improving their ability to handle complex faults.

[0091] Optionally, in some embodiments, it further includes:

[0092] S200: Record the cumulative number of repeated head breaks monitored within a specified time period at the current head break position.

[0093] In this embodiment, the specified time period is one week. This application counts the cumulative number of repeated decapitations detected at the current decapitation location within one week.

[0094] S210. When the number of repeated decapitations exceeds the first threshold, mark the current decapitation position.

[0095] The first threshold is 10 times. When the number of times exceeds 10, it is marked, and the permission for the head handling suggestion corresponding to the current head break position is changed to advanced permission.

[0096] S220. When the number of repeated breakages exceeds the second threshold, suspend the operation of the spindle position corresponding to the current breakage position.

[0097] The second threshold is set according to the specific equipment conditions. When frequent spindle breakage occurs, the corresponding spindle position needs to be stopped for more comprehensive inspection and treatment.

[0098] Secondly, this application provides a yarn breakage management system based on online monitoring. The online monitoring-based yarn breakage management system of this application will be described below in conjunction with the aforementioned online monitoring-based yarn breakage management method. Please refer to... Figure 4 , Figure 4 This is a schematic diagram of a yarn breakage management system based on online monitoring, according to an embodiment of this application.

The breakage handling suggestions include those that can be handled by ordinary permissions and those that can be handled by advanced permissions.

[0103] The mobile display module 140 is used to control the movable operation screen to move to one of the broken ends, and to control the movable operation screen to display all broken ends, the broken end factors of the current broken end, broken end handling suggestions, and operation videos.
