[0014] Before describing the technical proposals relating to the embodiments of this disclosure, we will further explain the technical terms that may be used in this disclosure.

[0015] MES is a software system for monitoring and managing the manufacturing process, which can collect, process, and analyze production data in real time and optimize production planning and resource allocation. PLC is an industrial digital computer used to control automation equipment such as mechanical devices and robots on the production line. The PLC can perform logical operations and processing on input signals according to a pre-set program and output control signals to control the operation of the equipment. Business data refers to data related to operations generated during the manufacturing process, such as equipment status, product quantity, production progress, etc. These data serve as the basis for decision-making and control by MES and PLC. Transfer instruction information (also called transfer command) is generated after MES analyzes the business data, and is command and parameter information for instructing equipment to execute transfer tasks.

[0016] Figure 1 shows a schematic diagram of the control system for the automatic transfer of winding packages. As shown in Figure 1, the control system for the automatic transfer of winding packages includes MES, a first PLC, and a plurality of second PLCs. The plurality of second PLCs are respectively connected to the first PLC, and the first PLC is connected to MES. Each second PLC is responsible for controlling at least one work station. Here, the second PLC mainly collects and processes real-time business data of the target work station and provides it to the first PLC. The first PLC is responsible for interacting with the second PLC and obtaining second business data from the second PLC. The first PLC also plays a role in interacting with MES, sending first business data to MES, receiving transfer instruction information distributed by MES based on the first business data, and notifying the second PLC to execute the transfer instruction information for the target work station.

[0017] In some embodiments, the MES is configured to determine transfer instruction information for a target work station based on first business data transmitted from a first PLC and return the transfer instruction information to the first PLC.

[0018] In some embodiments, the first PLC is configured to obtain first business data for the target work station based on second business data for the target work station obtained from a second PLC.

[0019] In some embodiments, each second PLC is configured to obtain and store second business data of a target work station managed by the second PLC.

[0020] Here, the first business data is collected and processed by the first PLC, and is a data set related to information such as the real-time state of the target work station, the processing progress of the winding package, the detection result of the quality of the winding package, and the required type. These data have important significance in monitoring the operating state of the production line and permitting transfer decision-making.

[0021] Here, the second business data is collected and processed by the second PLC, and is a data set related to information such as the real-time state of the target work station, the processing progress of the winding package, the detection result of the quality of the winding package, and the barcode of the winding package. These data have important significance for monitoring the operating state of the production line.

[0022] The automated transfer control system for yarn packages according to the embodiment of this disclosure enables the MES to monitor the status of each work station in real time and adjust and optimize as needed through real-time communication and data processing between the MES, the first PLC, and the second PLC. This automated control reduces manual intervention, improves the efficiency and accuracy of yarn package transfer, reduces material waste and downtime due to human error, and lowers production costs. This automated control ensures the stability and consistency of yarn packages during the transfer process, contributing to an improvement in overall production rhythm and efficiency. By making the first PLC an intermediate layer between the MES and multiple second PLCs, the automated transfer control system for yarn packages has significant advantages in terms of centralized management, data integration, reduced MES load, improved system scalability, improved safety and stability, and simplified network structure.

[0023] If the MES communicates directly with multiple second PLCs, it will need to process a large amount of real-time data and requests, potentially increasing the load on the MES and impacting its performance. On the other hand, by using a first PLC as an intermediate layer, the MES only needs to communicate with the first PLC, reducing its processing burden. Without a first PLC as an intermediate layer, the MES would need to establish direct communication connections with each second PLC, resulting in a complex and difficult-to-manage network configuration. By using a first PLC as a relay, the network configuration can be significantly simplified, making the entire communication process clearer and more orderly. The first PLC acts as a safety barrier, verifying and filtering data from the second PLCs to prevent malicious or erroneous data from entering the MES system. Furthermore, the redundancy and fault tolerance mechanisms of the first PLC improve system stability and reliability, ensuring that the production line continues to operate normally even if some equipment fails.

[0024] As production lines expand and are upgraded, it may be necessary to add more second PLCs. If the MES communicates directly with each second PLC, the MES will need to be reconfigured and modified with each expansion. On the other hand, by using the first PLC as an intermediate layer, support for new second PLCs only needs to be added to the first PLC, eliminating the need to change the MES configuration. The first PLC can centrally receive operational data from multiple second PLCs and perform batch processing and analysis. This method allows for more centralized and orderly control of the entire production line, reducing the complexity and confusion that arises when the MES communicates directly with multiple second PLCs. The first PLC can integrate data from different second PLCs to form a more comprehensive production view, allowing the MES to make decisions based on more comprehensive data and further optimize production planning and resource allocation. The first PLC can also pre-process and filter the data, reducing the amount of data transmitted to the MES and improving communication efficiency.

[0025] Embodiments of the present disclosure provide a method for controlling the automatic transfer of a yarn package, Figure 2 being a flowchart of the method for controlling the automatic transfer of a yarn package according to an embodiment of the present disclosure, the method for controlling the automatic transfer of a yarn package can be applied to a control device for the automatic transfer of a yarn package, the control device for the automatic transfer of a yarn package is installed in electronic equipment applied to the control system for the automatic transfer of a yarn package, the electronic equipment includes, but is not limited to, fixed equipment and / or mobile equipment. For example, fixed equipment includes, but is not limited to, a server, and the server may be a cloud server or a general-purpose server. For example, mobile equipment includes, but is not limited to, a mobile phone, a tablet computer, a laptop computer, etc. In some possible embodiments, the method for controlling the automatic transfer of a yarn package may be implemented by a processor calling computer-readable commands stored in memory. As shown in Figure 2, the method for controlling the automatic transfer of a yarn package includes the following steps.

[0026] S201: The first PLC obtains the second business data for the target work station from the second PLC corresponding to the target work station, and obtains the first business data for the target work station based on the second business data.

[0027] S202: If the connection between the first PLC and the MES is disconnected, the first PLC records the first operational data and transmits the transfer instruction information to the second PLC so that the second PLC controls the target work station based on the transfer instruction information to perform the transfer task of the spool package. Here, the transfer instruction information is a transfer permission.

[0028] In some embodiments, each second PLC collects and processes relevant second operational data (e.g., location, status, and quantity of yarn packages) based on the state of the work station it controls, and stores this data in a data storage area, such as data blocks (DB blocks), that the second PLC assigns to the work station it is responsible for.

[0029] In some embodiments, the first PLC acquires second operational data for each work station from each second PLC and generates first operational data for each work station. This first operational data includes the status and operation information to be performed for all relevant work stations. The MES analyzes the first operational data to determine the transfer instruction information for the target work station (i.e., the work station that should now perform the transfer operation of the spool package). The transfer instruction information includes transfer permission and transfer prohibition. Here, if the transfer instruction information is a transfer permission, it may further include parameters such as the specific time of transfer, target position, and speed. The MES transmits the generated transfer instruction information to the first PLC via a network or other communication method such as a Management Interface (MI).

[0030] In some embodiments, the first PLC receives transfer instruction information from the MES, performs analysis processing, and extracts specific control commands and parameters. After completing the analysis, the first PLC transmits the analysis results (i.e., specific control commands and parameters) to a second PLC corresponding to the target work station via a communication interface or communication protocol. After receiving the analysis results, the second PLC controls the transfer equipment, such as machinery or robots at the target work station, based on the control commands and parameters in the analysis results to perform the transfer task of the spool package.

[0031] In some embodiments, the communication protocol and parameters between the first PLC and the second PLC are configured at system startup to ensure stable communication between them. The connection between the first PLC and the MES is configured to ensure that the first PLC can send first business data to the MES and receive transfer instruction information returned from the MES. The first PLC actively acquires second business data for the target work station (e.g., current operating status, number of spool packages awaiting processing, processing time, etc.) from the second PLC corresponding to the target work station. After acquiring the second business data, the first PLC converts this data into first business data (e.g., whether transfer conditions are met, estimated transfer time, etc.) according to a pre-configured algorithm or logic. If the connection between the first PLC and the MES is interrupted for any reason (e.g., network failure, MES maintenance, etc.), the first PLC automatically switches to offline operation mode. In this mode, the first PLC records the first operational data and transmits transfer instruction information (e.g., a signal such as "transfer permitted") to the second PLC. After receiving the transfer instruction information, the second PLC controls the target work station to perform the transfer task of the yarn package, including moving the yarn package to the next work station and updating status information. Once the connection between the first PLC and the MES is restored, the system can automatically synchronize the data and adjust subsequent operations based on the latest commands from the MES.

[0032] For example, suppose a production line has multiple work stations, each responsible for a different processing task. The first PLC periodically retrieves the second work data for the current work station from the second PLC. After processing a yarn package at a certain work station (e.g., a work station for measuring weight) is complete, the process needs to move to the next step. If the MES (Manual Energy Execution System) becomes temporarily unavailable, the first PLC sends a transfer instruction message, called "transfer permission," to the second PLC in place of the MES. The second PLC then sends a command to the transfer equipment (e.g., a conveyor or robotic arm) to transport the processed yarn package to the next work station (e.g., a work station for measuring winding diameter) for subsequent processing.

[0033] The main types of wound yarn packages relating to the technical proposals of the embodiments of this disclosure may include one or more types such as partially oriented yarns (POY), fully drawn yarns (FDY), and drawn textured yarns (DTY) (or referred to as low-elasticity yarns). For example, the yarn types may specifically include polyester partially oriented yarns, polyester fully drawn yarns, polyester drawn yarns, polyester low-elasticity yarns (Polyester Draw Textured Yarns), and polyester staple fibers (PSF).

[0034] In the technical proposals of the embodiments of this disclosure, real-time communication and data processing between the MES, a first PLC, and multiple second PLCs allows the MES to monitor the status of each work station in real time and adjust and optimize the transfer strategy as needed. Even if the connection between the first PLC and the MES is lost, the system can operate independently and complete the transfer task, thereby improving the stability and reliability of the system. Automatic offline forced transfer control reduces manual intervention, improves the transfer speed and accuracy of the spool package, and reduces production and time costs due to human error or delays.

[0035] In embodiments of the present disclosure, the second PLC controlling a target work station based on transfer instruction information to perform a transfer task of a spool package includes, if the transfer instruction information is a transfer permission, the second PLC notifying the transfer equipment or directly controlling the transfer equipment to transport the processed spool package at the target work station to the next work station of the target work station.

[0036] Here, transfer equipment refers to automated equipment such as conveyors, robotic arms, and automated guided vehicles used to transport materials (e.g., yarn packages) between different work stations on a production line. The above is merely an illustrative explanation and does not limit all possible equipment included in transfer equipment; it is not exhaustive.

[0037] In some embodiments, the transfer instruction information may include the evaluation result by the first PLC of whether the winding package at the target work station satisfies the transfer conditions, for guiding subsequent control operations.

[0038] In some embodiments, if the transfer instruction information is "transfer permission," the second PLC transmits a command or signal to the transfer equipment to inform it to prepare for transporting the processed spool packages at the target work station. After receiving the command from the second PLC, the transfer equipment transports the spool packages from the target work station to the next work station according to a pre-configured program or route. During the transport process, a series of actions may occur with respect to the spool packages, such as gripping, carrying, and placing, and all of these actions must be precisely controlled to ensure the safe and accurate transport of the spool packages.

[0039] In some embodiments, the second PLC continuously monitors the operating status of the transfer equipment and the transport status of the spool packages. Once transport is complete, the transfer equipment sends a feedback signal to the second PLC to confirm that the current spool package has successfully arrived at the next work station. The second PLC updates its internal state based on the feedback signal and prepares for subsequent control operations.

[0040] For example, suppose a production line has multiple work stations, each responsible for a different processing task. After processing of a yarn package at one work station (e.g., a work station for measuring weight) is complete, a second PLC receives the analysis results from that work station and determines "transfer permitted" if the forced transfer variable is 1, regardless of whether parameters such as weight, specifications, and lot number meet the requirements. The second PLC then sends a command to the transfer equipment (e.g., a conveyor or robotic arm) to transport the processed yarn package to the next work station (e.g., a work station for measuring winding diameter) for subsequent processing.

[0041] Thus, the first PLC and multiple second PLCs enable precise control of the yarn package transfer process, reducing waiting times and manual intervention, improving the overall efficiency of the production line, reducing errors due to human factors, and enhancing the stability and reliability of the production process. The PLC programming is flexible, allowing for quick adjustment of the control logic according to production needs and adapting to the processing of different types and specifications of yarn packages. The first PLC's ability to handle forced transfer significantly reduces the time yarn packages remain at the work station, improving the overall smoothness of the production line and effectively reducing energy consumption and labor costs.

[0042] In embodiments of the present disclosure, the control method for the automatic transfer of the winding package further includes determining that the connection between the first PLC and the MES has been disconnected when the first PLC detects that a control button corresponding to the first PLC has been rotated to offline mode.

[0043] In some embodiments, offline mode typically refers to a state in which the system operates independently without communicating with a higher-level management system (e.g., MES). In such mode, the system can perform control tasks according to its own logic and pre-configured parameters.

[0044] In some embodiments, a control button is a physical switch or knob for controlling the operating mode of the first PLC. The control button is used to switch the operating mode of the first PLC (e.g., online mode or offline mode). Offline mode is indicated by a specific position or mark on the control button, and when the button is rotated to that position, it indicates that offline mode has been selected to actively interrupt communication with the MES. Online mode is indicated by a specific position or mark on the control button, and when the button is rotated to that position, it indicates that online mode has been selected to maintain communication with the MES.

[0045] In some embodiments, the first PLC continuously monitors the state of a control button directly connected to it, which is typically mounted on an operation panel and allows an operator to manually switch the operating mode of the first PLC. When the first PLC detects that the control button has been rotated to the "offline mode" position, it immediately records this event and considers that the connection to the MES has already been disconnected or is about to be disconnected. Such a detection method is immediate and reliable because it relies primarily on hardware signals (e.g., the on / off state of the button). After determining that it is in offline mode, the first PLC retrieves second business data for the target work station from the second PLC according to a predetermined flow and converts it into first business data. Based on the processed first business data, the first PLC decides whether to send transfer instruction information to the second PLC to control the transfer task of the spool package. Generally, the first PLC sends transfer instruction information to the second PLC that reads "transfer permitted". The system is equipped with the capability to handle various abnormal situations and automatically synchronizes data and restores connectivity with the MES when conditions are restored.

[0046] Taking an automated packaging line in the chemical fiber industry as an example, a network failure may cause the MES to temporarily lose communication with the first PLC. In this case, the operator can go to the control panel where the first PLC is located and rotate the control button to "offline mode". After detecting this change, the first PLC automatically determines that the connection with the MES has already been lost and immediately activates the transfer control flow in offline mode. Subsequently, the first PLC sends a transfer instruction message to the second PLC, indicating "transfer permission," to ensure that the yarn package can be smoothly moved from the current work station to the next work station.

[0047] By introducing control buttons in this way, operators can directly intervene in the production process in specific situations, improving the system's flexibility and ability to handle unexpected events. By allowing operators to manually switch the operating mode of the first PLC, the system can quickly adjust its operating state according to actual needs, improving the system's flexibility and adaptability. State detection for the control buttons provides intuitive indication of the connection status between the first PLC and the MES, helping to find and handle connection problems, thus improving the system's reliability. If the MES is unavailable, operators can easily switch the first PLC to offline mode by rotating the control button, allowing the system to continue performing transport tasks, simplifying the operating process and reducing downtime.

[0048] In embodiments of the present disclosure, the control method for the automatic transfer of the winding package further includes determining that the connection between the first PLC and the MES has been disconnected when the first PLC detects that communication between the first PLC and the MES has been interrupted.

[0049] In some embodiments, a communication interruption refers to a state in which, during the communication process, the communication link is unable to transmit data properly due to various causes (e.g., network failure, device failure, signal interference, etc.).

[0050] In some embodiments, the first PLC integrates a communication status monitoring module that continuously monitors the communication link with the MES. The monitoring includes, but is not limited to, key indicators such as the success rate of sending and receiving data packets, communication delay, and the number of timeouts. If an abnormality occurs in the communication link (e.g., failure to send multiple consecutive data packets, communication delay exceeding a predetermined threshold, or the number of timeouts reaching its upper limit), the PLC determines that communication has been interrupted. If communication has been interrupted, the first PLC immediately records this event and considers the connection with the MES to be disconnected. Subsequently, the first PLC switches to offline operation mode. In offline operation mode, the first PLC continues to acquire second business data for the target work station from the second PLC and converts it into first business data. Based on the processed first business data, the first PLC decides whether or not to send transfer instruction information to the second PLC to control the transfer task of the spool package. When the first PLC detects that the communication link with the MES has been successfully restored, it automatically switches to online operation mode. In online operation mode, the first PLC performs synchronization operations with the MES to ensure data consistency and accuracy.

[0051] Assume that in an automated production line, the first PLC is responsible for monitoring and managing the operating status of multiple yarn package processing work stations. If, one day, the communication link between the first PLC and the MES is interrupted due to a network failure, the first PLC's communication status monitoring module immediately detects this anomaly and determines that communication has been interrupted. Subsequently, the first PLC automatically switches to offline operation mode, continuing to acquire operational data from the second PLC and controlling the yarn package transfer task. After the network failure is resolved, the communication link is restored to normal, and the first PLC resumes synchronization operations with the MES to ensure data consistency and accuracy.

[0052] In this way, by automatically detecting communication interruptions and switching to offline operation mode, the system can continue performing control tasks when the MES becomes unavailable, eliminating the need for manual intervention and improving the degree of system automation. The automatic detection and handling mechanism for communication interruptions enables the system to handle various communication failures, improving system stability and reliability. After communication is restored, the system can automatically synchronize data and return to a normal operating state, reducing downtime due to communication problems.

[0053] In embodiments of the present disclosure, the method for controlling the automatic transfer of the winding package further includes the condition that, if the connection between the MES and the first PLC is disconnected, the MES does not perform the process for determining the online transfer conditions.

[0054] In some embodiments, when communication between the MES and the lower-level control system is interrupted, the MES performs a series of alternative processes that do not rely on real-time data in order to maintain the normal operation of the system.

[0055] In some embodiments, the online transfer condition determination process includes the MES evaluating and analyzing received operational data according to predetermined rules and algorithms to determine whether the target work station is permitted to perform the transfer operation. These conditions may include various factors such as production plans, equipment status, and material supply status.

[0056] In some embodiments, upon receiving first business data transmitted from a first PLC, the MES first performs data reception and initial verification. If the data format is accurate and includes valid mandatory transport variables, the MES fully records this data in its internal database or log system to facilitate tracking of subsequent data. The recorded content may include key fields of all or part of the first business data, and information such as a timestamp when the data was received. If successful, the MES determines whether to permit transport at the target work station by performing an online transport condition determination process on the received business data based on predetermined rules and algorithms.

[0057] In some embodiments, a stable communication connection is established between the MES and the first PLC, and the status of this connection is continuously monitored. When the first PLC detects that communication with the MES has been interrupted, it notifies the MES using a predetermined communication protocol or heartbeat mechanism. Upon receiving the communication interruption notification from the first PLC, the MES immediately recognizes that the current connection with the first PLC is disconnected. The MES immediately stops executing any online transport condition determination processes that rely on real-time communication with the first PLC. The MES may initiate an offline processing strategy that may include recording the communication interruption event, sending an alarm to the system administrator, and (if applicable) performing some predictive processing based on predetermined rules or historical data. In any case, the MES does not perform any online transport condition determinations that require real-time data acquisition from the first PLC. When the first PLC detects that communication with the MES has been restored, it notifies the MES again. When the MES receives notification that communication has been restored, it re-establishes communication with the first PLC and resumes the process of determining the online transport conditions.

[0058] Taking an automated packaging line in the chemical fiber industry as an example, the MES (Manufacturing Execution System) is responsible for monitoring the entire production flow and determining whether the yarn package meets the transfer conditions based on real-time data. However, due to a network failure, communication between the MES and the first PLC (Programmable Logic Controller) may be suddenly interrupted. In such a case, the MES immediately stops executing the online transfer condition determination process and records this event in the system log. Moreover, the system administrator receives an alarm about the communication interruption and immediately begins investigating the fault. After the fault is resolved, communication is restored, the MES re-establishes its connection with the first PLC, and resumes the online transfer condition determination process.

[0059] In this way, during communication interruptions, the MES reduces the consumption of computing resources by not performing unnecessary online transport condition determinations. By avoiding processing that relies on real-time data during communication interruptions, it reduces potential system problems caused by data inconsistencies or errors. System administrators can receive timely alerts about communication interruptions and intervene as needed, improving system maintainability and user experience.

[0060] In embodiments of this disclosure, the online transfer condition determination process may include determining whether the spool package at the target work station satisfies the transfer conditions based on target string data corresponding to the target work station, determining that the transfer instruction information is transfer permitted if the transfer conditions are met, and determining that the transfer instruction information is transfer prohibited if the transfer conditions are not met. Here, the target string data is obtained by the MES analyzing the first business data.

[0061] In some embodiments, the transfer instruction information is information that indicates whether the yarn package in the production line can be subsequently transported to the next work station for processing. Depending on the determination of the transfer conditions, the transfer instruction information may be "transfer permitted" or "transfer prohibited."

[0062] In some embodiments, the MES first receives first operational data transmitted from a first PLC. This data typically includes status information of a target work station on the production line, processing progress of the yarn package, quality detection results, and the transfer request number. The MES includes a dedicated data analysis module for analyzing the received first operational data and extracting target string data corresponding to the target work station. This target string data may be encoded and represents a specific operating state or attribute.

[0063] In some embodiments, the MES further analyzes the target string data obtained through analysis by comparing it with predetermined transport conditions. These transport conditions may include whether the processing quality of the spool package has met the target, whether all processing tasks at the current work station have been completed, and whether there is any equipment failure or production abnormality. If the spool package at the target work station meets all predetermined transport conditions, the MES determines that the transport instruction information is "transport permitted," indicating that the spool package can be safely transported to the next work station for processing. If the spool package at the target work station does not meet any of the transport conditions, the MES determines that the transport instruction information is "transport prohibited," and can notify on-site staff to inspect and process the package by triggering the corresponding alarm mechanism.

[0064] In some embodiments, the MES transmits the determination result (transfer permitted or transfer prohibited) as transfer instruction information to a second PLC or other related control equipment via a communication interface. Based on the received transfer instruction information, these transfer equipment executes the corresponding control logic, for example, starting or stopping the transport operation of the spool package.

[0065] Taking an automated packaging line in the chemical fiber industry as an example, the first PLC detects that processing of a yarn package at a certain work station (e.g., a work station for measuring weight) is complete, and then transmits first operational data, including status information of the work station, to the MES. After receiving the data, the MES first obtains target string data (e.g., the QR code® of the yarn package for the transfer request, weight information) through analysis, and then compares it with predetermined transfer conditions (e.g., whether the weight of the yarn package of this standard is within the acceptable range; Grade A: within the acceptable range, Grade B: too light, Grade C: too heavy). If the quality level of the yarn package is Grade A, the MES determines that the transfer instruction information is "transfer permitted" and notifies the second PLC to start the transport operation of the yarn package. If the quality level of the yarn package is Grade B or C, the MES determines that "transfer prohibited" and triggers an alarm mechanism.

[0066] Thus, by analyzing the first operational data and precisely determining the transport conditions using MES, it is possible to ensure that only spool packages that meet the requirements are transported, thereby improving the accuracy and reliability of production. Furthermore, by timely detection and prevention of the transport of spool packages that do not meet the transport conditions, abnormal situations in the production process, such as equipment failures and quality problems, can be reduced, thereby lowering production risks. By automatically determining and issuing instructions for transport information, manual intervention and waiting times can be reduced, improving the overall operational efficiency of the production line.

[0067] In the embodiments of this disclosure, the acquisition of second business data for a target work station by a first PLC from a second PLC corresponding to a target work station includes the first PLC periodically acquiring the second business data for a target work station from the second PLC.

[0068] In some embodiments, the first PLC is equipped with a timer for controlling the time interval for data acquisition. This time interval can be adjusted according to the actual needs of the production line to ensure that the latest data is acquired in a timely manner, while also avoiding increased system load due to frequent data exchange. When the timer reaches the set time, the first PLC sends a data request signal to the second PLC. This signal includes information such as the type of data to be acquired and the identifier of the target work station, so that the second PLC can accurately return the corresponding data.

[0069] In some embodiments, after receiving a data request from the first PLC, the second PLC retrieves the second operational data for the target work station from its own database or a real-time data buffer based on the information in the request and transmits it to the first PLC via a communication interface. This data may include the real-time status of the target work station, processing progress, quality detection results, etc.

[0070] In some embodiments, the first PLC acquires second business data, then analyzes and processes the second business data to extract information necessary for subsequent decision-making or control operations. This data may then be used to update related data or generate reports in the MES.

[0071] In this way, by periodically acquiring second operational data from the target work station from the second PLC, it is possible to monitor the status of the production line in real time, ensuring transparency and traceability of the production process. Based on real-time data, the MES or the first PLC can promptly detect abnormal conditions in the production process and take appropriate adjustment measures, such as stopping transfers or adjusting process parameters, to improve production efficiency and product quality. By analyzing historical and real-time data, it is possible to provide strong support for decision-making to optimize the production line, such as predicting production trends and optimizing production plans.

[0072] In embodiments of the present disclosure, the acquisition of first business data by a first PLC based on second business data of a target work station obtained from a second PLC corresponding to the target work station includes the first PLC converting the second business data into first business data in a data storage format according to a pre-configured data storage format, where the first business data is stored in a data storage area assigned by the first PLC to the target work station, and different types of variables in the first business data correspond to different fixed addresses in the data storage area.

[0073] Here, a data storage format is a specific format or specification used during the storage or transmission of data, and includes the data type, data units, data encoding, etc.

[0074] Here, the data storage area is a specific area within the first PLC for storing data.

[0075] Here, a fixed address is a unique and immutable memory location within the data storage area that is assigned to a different variable. Fixed addresses enable rapid access to and modification of variables.

[0076] In some embodiments, in an automated transfer control system for yarn packages, a first PLC is responsible for generating first operation data for a target work station based on second operation data for that work station. This data may include various types of information, such as status codes, numerical parameters, and timestamps. A pre-configured data storage format is placed inside the first PLC to ensure that data can be efficiently exchanged and analyzed between different PLCs or between a PLC and an MES. The first PLC converts the second operation data according to this pre-configured format. The conversion process may include conversion of data types (e.g., integer to floating-point), unification of data units (e.g., millimeter to inch), and decoding of encoded data (e.g., number system conversion). The converted data is first operation data and, since it conforms to the pre-configured data storage format, subsequent processing and transmission can be facilitated. The first PLC allocates a dedicated data storage area to each target work station in the production line. The first operation data is stored in the data storage area corresponding to the target work station. During storage, different variables (e.g., status codes, numerical parameters, etc.) are assigned to different fixed addresses in the storage area. When it is necessary to read or modify the value of a variable, it can be accessed directly using its corresponding address, thereby improving the efficiency of data processing.

[0077] Thus, the pre-configured data storage format and format conversion process ensure consistency and accuracy in the exchange and processing of data from different sources. Assigning a fixed storage address to each variable simplifies data access and processing, improving overall system performance. The allocation of data storage areas and the definition of the format offer a degree of flexibility, allowing for expansion and adjustment according to the actual needs of the production line.

[0078] In the following, using IT-PLC as an example to represent the first PLC and ME-PLC as the second PLC, we will explain the processing flow of the first PLC, which is the intermediate layer between the MES and the second PLC.

[0079] Figure 3 shows a flowchart of the process by which the first PLC generates offline forced transfer instruction information for the second PLC. As shown in Figure 3, the flow includes the following steps.

[0080] S301: The system is starting up.

[0081] S302: The IT-PLC periodically retrieves ME_CTRL_WRD and REQUEST_TYPE from the DB block of the corresponding workstation in the ME-PLC. Here, ME_CTRL_WRD represents the control digit of the target work station, and REQUEST_TYPE represents the request type of the target work station.

[0082] Furthermore, to ensure data integrity and accuracy, the ME-PLC should check the ME_MSG.ME_AVI_MSG file that it has written to the DB block of its corresponding work station.

[0083] For example, ME_CTRL_WRD is obtained from DB6101.ME_MSG.ME_CTRL_WRD, and REQUEST_TYPE is obtained from DB6101.ME_MSG.ME_AVI_MSG. Here, 6101 is the number of the target work station, DB6101.ME_MSG represents the DB block that the ME-PLC has assigned to work station number 6101, DB6101.ME_MSG.ME_AVI_MSG represents a variable that the ME-PLC has assigned to work station number 6101 and stores the second business data written by the ME-PLC, and ME_MSG.ME_AVI_MSG represents the second business data written to the ME-PLC, such as the serial number and request type. DB6101.ME_MSG.ME_CTRL_WRD is a variable assigned by the ME-PLC to the workstation number 6101, and it stores the control digit of that workstation in the DB block.

[0084] S303: Determine whether DB6101.ME_MSG.ME_AVI_MSG.REQUEST_TYPE is "TRM*". If the result is YES, execute S304. If the result is NO, continue executing S302.

[0085] Here, the IT-PLC retrieves ME_AVI_MSG.REQUEST_TYPE="TRM*" from the DB block of the corresponding workstation in the ME-PLC.

[0086] Here, ME_AVI_MSG.REQUEST_TYPE="TRM*" indicates that the ME-PLC request type is "TRM*". When the ME-PLC recognizes that the target work station is requesting a forced transfer, it writes the string "TRM*" to the transfer information of the current work station to distinguish it from the string "TR**" used for normal online transfers.

[0087] Here, DB6101.ME_MSG.ME_AVI_MSG.REQUEST_TYPE is a variable assigned by the ME-PLC to the workstation number 6101, and it stores the request type in the DB block.

[0088] S304: The IT-PLC sets the control digits and clears the data buffer area to ensure that the current flow is not affected by residual data from other flows, and then executes S305.

[0089] S305: Determine whether DB6101.ME_MSG.ME_CTRL_WRD.ASSY_COMPLETE_FORCE is 1. If the result is YES, execute S306; otherwise, continue executing S305.

[0090] Here, the IT-PLC retrieves ME_CTRL_WRD.ASSY_COMPLETE_FORCE from the DB block of the corresponding workstation in the ME-PLC. Here, ME_CTRL_WRD.ASSY_COMPLETE_FORCE=1 indicates that the ME-PLC has already set and initiated forced transfer.

[0091] DB6101.ME_MSG.ME_CTRL_WRD.ASSY_COMPLETE_FORCE is a variable in the DB block that the ME-PLC has assigned to the work station number 6101 and that the ME-PLC has already set up and initiated the forced transfer.

[0092] S306: The IT-PLC sets DB6101.IT_MSG.IT_CTRL_WRD.ASSY_COMPLETE_RECEIVED, and then executes S307.

[0093] Here, IT_MSG.IT_CTRL_WRD.ASSY_COMPLETE_RECEIVED indicates that the IT-PLC has received a message that the ME-PLC has already set up and initiated the forced transfer. DB6101.IT_MSG indicates the DB block that the IT-PLC has assigned to workstation number 6101.

[0094] DB6101.IT_MSG.IT_CTRL_WRD.ASSY_COMPLETE_RECEIVED is a variable used to store that the IT-PLC has received a message indicating that the ME-PLC has already set up and initiated forced transfer of the DB block assigned to workstation 6101.

[0095] S307: Construct MI_MSG and write DB6240.MI_MES_REQUEST. Here, MI_MSG represents the first business data sent by the IT-PLC to the MES. Here, MI_MES_REQUEST indicates the request string sent by the IT-PLC to the MES.

[0096] DB6240.MI_MES_REQUEST is a variable used to store the request string in the DB block that the IT-PLC has assigned to workstation 6101.

[0097] S308: Determine whether DB6240.MI_MES_REQUEST is "<>". If the result is YES, execute S309. If the result is NO, continue executing S308. Here, "<>" represents a pre-configured invoice string value, which can be set or adjusted according to the needs.

[0098] Call S309:FC64017 to store the MI_MSG for forced transport in the queue on DB6240. Here, FC64017 is an integrated module that has the function of writing MI_MSG. DB6240 is a DB block for storing MI_MSG that the IT-PLC has assigned to workstation 6101.

[0099] S310: Generate IT_RES_1. Here, IT_MSG.UDT_IT_MSG_1.IT_RES_1 (abbreviated as IT_RES_1) represents the first business data output by the IT-PLC, such as the processing result.

[0100] For example, IT_RES_1 may include SN1 = "**********************" (20*), RESPONSE_RESULT = 1, and RESPONSE_ERROR = 0.

[0101] Here, the predefined data exchange rules include the following: In the case of offline forced transport, SN1 represents the 2D code, barcode information, etc. of the spool package, and SN1 is 20 asterisks returned directly from the IT-PLC. The ME-PLC does not perform any processing (e.g., string matching, checking whether the returned item is information for the spool package) upon receiving the 20 asterisks, thereby improving the system's processing speed. RESPONSE_RESULT=1 indicates that processing for the current transport request has been completed, and RESPONSE_ERROR=0 indicates that the current transport request is normal and there are no abnormal conditions.

[0102] In addition to Figure 3, Figure 4 shows a flowchart of the process in which the first PLC generates offline forced transfer instruction information and then returns the offline forced transfer instruction information to the second PLC. As shown in Figure 4, the flow includes the following steps.

[0103] Call S311:FC60157 to update the queue on the production line. Here, the FC60157 is a module that integrates functions for updating queues on the production line.

[0104] S312: IT-PLC clears AVI_RESPONSE1. Here, AVI_RESPONSE1 indicates that the MES has finished sending the response string to the IT-PLC, and that the IT-PLC will generate and write the response string according to the defined rules during offline (forced) transport.

[0105] S313: The IT-PLC outputs IT_RES_1 to the ME-PLC.

[0106] S314: Determine whether the ERROR in the PUT command is 0 and the STATUS is 0000H. If the result is NO, execute S315. If the result is YES, execute S316.

[0107] Here, ERROR=0 indicates that there is no error in the PUT command. STATUS=0000H indicates that the status value is 0, where H represents a hexadecimal number. The PUT command is a command used by the IT-PLC to send data to the ME-PLC.

[0108] S315: Call FB64001 and write error code 3542, then return to S314.

[0109] S316: The IT-PLC sets DB6101.IT_MSG.IT_CTRL_WRD.MES_COMPLETE.

[0110] DB6101.IT_MSG.IT_CTRL_WRD.MES_COMPLETE is a variable used to store the notification from the IT-PLC to the ME-PLC that data processing is complete in the DB block that the IT-PLC has assigned to the workstation number 6101. Here, IT_MSG.IT_CTRL_WRD.MES_COMPLETE indicates that the IT-PLC notifies the ME-PLC that data processing is complete.

[0111] S317: Determine whether ME_CTRL_WRD.YARN_LEAVE=1 or ME_CTRL_WRD.ME_RESET is 1. If the result is YES, execute S318; otherwise, continue executing S317.

[0112] Here, ME_MSG.ME_CTRL_WRD.YARN_LEAVE=1 indicates that the ME-PLC is ready to detach the yarn package.

[0113] ME_CTRL_WRD.ME_RESET=1 indicates that the ME-PLC sets the control digit for a work station after it has controlled and completed the transfer of the spool package at that work station.

[0114] S318: The IT-PLC clears and resets the control digit corresponding to the work station and resets the business data area corresponding to the work station.

[0116] Here, DB6901 is assigned by the ME-PLC to the work station number 6101 and indicates an area for storing temporary variables in the DB block.

[0117] Here, DB6101.IT_MSG is assigned by the ME-PLC to the workstation number 6101 and represents a data buffer area for storing various variables in the DB block.
