[0014] Before explaining the technical solutions according to the embodiments of the present disclosure, further explanations will be given on the technical terms that can be used in the present disclosure.
[0015] MES: A software system for monitoring and managing the manufacturing process, capable of collecting, processing and analyzing production data in real time, and optimizing production planning and resource allocation.
[0016] PLC: An industrial digital computer used to control automation equipment such as mechanical devices and robots on the production line. It 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.
[0017] RFID: A communication technology that can identify a specific object by wireless signals and read and write related data without establishing mechanical or optical contact between the identification system and the specific object.
[0018] RFID site: A physical location or device where an RFID reader / writer is arranged, used to read and record RFID tag information passing through that location.
[0019] Business data: Data related to operations generated during the manufacturing process, such as equipment status, number of products, production progress, etc. These data serve as the basis for decision-making and control by MES and PLC.
[0020] Transfer instruction information (also called transfer command): Generated after MES analyzes business data, it is the command and parameter information for instructing equipment to execute transfer tasks.
[0021] Figure 1 shows a schematic diagram of a control system for automatic transfer of winding packages. As shown in Figure 1, the control system for automatic transfer of winding packages includes MES, a first PLC, and a plurality of second PLCs. The plurality of second PLCs are each 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 interacts with the second PLC and is responsible for obtaining the second business data from the second PLC. The first PLC also plays the role of interacting with MES, sending the first business data to MES, receiving the 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.
[0022] In some embodiments, MES is configured to determine transfer instruction information for the target work station based on the first business data sent from the first PLC and return the transfer instruction information to the first PLC.
[0023] In some embodiments, the first PLC is configured to obtain the first business data for the target work station based on the second business data for the target work station obtained from the second PLC.
[0024] In some embodiments, each second PLC is configured to acquire and store second business data for a target work station managed by the second PLC.
[0025] Here, the first operational data is collected and processed by the first PLC and is a data set containing information such as the real-time status of the target work station, the processing progress of the yarn package, the quality detection results of the yarn package, and the request type. This data is of great importance in monitoring the operating status of the production line and determining whether or not to grant permission for transfer.
[0026] Here, the second operational data is collected and processed by the second PLC and is a data set containing information such as the real-time status of the target work station, the processing progress of the yarn package, the quality detection results of the yarn package, and the barcode of the yarn package. This data is of great importance in monitoring the operating status of the production line.
[0027] 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.
[0028] 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.
[0029] 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 unified processing and analysis. This approach 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.
[0030] Embodiments of this disclosure provide a method for controlling the automatic transfer of a yarn package. Figure 2 is a flowchart of the method for controlling the automatic transfer of a yarn package according to an embodiment of this 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, which 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, which 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.
[0031] S201: If the control button of the first PLC is in online mode and communication between the first PLC and the MES is normal, the first PLC obtains the second business data for the target work station from the second PLC and transmits the first business data to the MES. The MES then performs the online transfer condition determination process based on the first business data and returns the transfer instruction information to the first PLC, where the first business data is generated by the first PLC based on the second business data and RFID information read from the RFID site corresponding to the target work station.
[0032] S202: When the first PLC receives transfer instruction information, it sends the analysis results for the transfer instruction information to the second PLC, which then controls the target work station based on the analysis results to execute the transfer task of the spool package.
[0033] 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 for switching the operating mode of the first PLC (e.g., online mode or offline mode). Offline mode is a specific position or mark on the control button, and when the button is switched to this position, it indicates that offline mode has been selected to actively interrupt communication with the MES. Online mode is a specific position or mark on the control button, and when the button is switched to this position, it indicates that online mode has been selected to maintain communication with the MES.
[0034] In some embodiments, it is checked whether the control buttons of the first PLC are in online mode to ensure that the system is operational. Next, it is checked whether communication between the first PLC and the MES is working correctly using the network communication protocol.
[0035] In some embodiments, after confirming that communication is successful, the first PLC obtains second operational data for the target work station from the second PLC via a predetermined communication interface, and this data may include information such as the current status, location, and production lot of the yarn package.
[0036] In some embodiments, the first PLC reads RFID information at an RFID site corresponding to the target work station, which typically includes key data such as a unique identifier for the yarn package and a production lot number. The first PLC combines the second business data with the RFID information to generate first business data that more comprehensively and accurately reflects the current state of the yarn package and the tasks to be performed.
[0037] In some embodiments, the first PLC transmits first business data to the MES, which then performs a determination process for online transfer conditions according to pre-configured business logic and rules (e.g., production plan, inventory status, equipment status, etc.). Based on the determination result, the MES generates transfer instruction information and returns it to the first PLC via a communication interface. The transfer instruction information clearly indicates whether or not to permit the transfer of the spool package, i.e., whether or not it can be continued to the next production stage.
[0038] In some embodiments, the first PLC, after receiving the transfer instruction information, performs an analysis to determine whether the transfer is "permitted" or "prohibited." If the analysis result is permitted, it notifies the transfer equipment or directly controls the transfer equipment to transport the processed yarn package at the target work station to the next work station. If the analysis result is prohibited, it notifies the transfer equipment or directly controls the transfer equipment to prohibit the execution of the yarn package transfer task at the target work station, and retransmits the second operational data to the target work station. If the transfer is prohibited, it may also trigger an alarm mechanism to notify the operator or perform other corresponding actions.
[0039] Here, "transfer equipment" refers to automated equipment used to transport materials (e.g., yarn packages) between different work stations on a production line, such as conveyors, robotic arms, and automated guided vehicles. The above is merely an illustrative explanation and does not limit all possible equipment included in transfer equipment; it is not exhaustive.
[0040] 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 operational 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 currently needs to 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).
[0041] 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.
[0042] 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 yarn 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.
[0043] 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.
[0044] 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).
[0045] The technical solution according to the embodiments of this disclosure enables real-time communication and data processing between the MES, a first PLC, and multiple second PLCs, allowing the MES to monitor the status of each work station in real time and adjust and optimize the transfer strategy as needed. By combining RFID technology with real-time data from the MES system, accurate judgments regarding transfer conditions can be ensured, reducing production problems caused by human error. Automated control reduces manual intervention and improves the accuracy and efficiency of winding package transfer. The system can flexibly adjust the transfer strategy based on real-time commands from the MES and adapt to different production demands. Real-time collection, processing, and feedback of production data can be achieved, providing robust data support for winding package production management.
[0046] In embodiments of the present disclosure, the control method for the automatic transfer of the winding package further includes the first PLC detecting that a control button corresponding to the first PLC has been switched to offline mode, and determining that the connection between the first PLC and the MES has been disconnected.
[0047] 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 switched to the "offline mode" position, it immediately records the 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.
[0048] 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 switch 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 transport control flow in offline mode. Subsequently, the first PLC sends a transport instruction message to the second PLC, "transport permitted," to ensure that the spool package can move smoothly from the current work station to the next work station.
[0049] By introducing control buttons in this way, operators can directly intervene in the production flow in specific situations, improving the system's flexibility and ability to handle unexpected events. State detection for the control buttons provides intuitive indication of the connection status between the first PLC and the MES, contributing to the timely detection and resolution of connection problems, thus improving system reliability. If the MES is unavailable, the operator can easily switch the first PLC to offline mode by rotating the control button, allowing the system to continue performing transport tasks, simplifying the operation process and reducing downtime.
[0050] In some embodiments, the second business data is generated by the second PLC based on the execution results of tasks corresponding to the target work station.
[0051] Here, the task execution result is the result information generated after the target work station has executed a specific production task, and reflects the completion status of the task. This includes, but is not limited to, the task completion status, time taken, and quality detection results.
[0052] Here, the second business data is a set of data generated by the second PLC based on the task execution results and used for subsequent processing (e.g., transport decision).
[0053] In some embodiments, the second PLC acts as the direct control unit for the target workstation, responsible for executing and monitoring production tasks at that workstation. These tasks may include processing, detecting, and packaging of spooled yarn packages. During task execution, the second PLC collects relevant data in real time, such as start time, end time, execution status (success, failure, pause, etc.), production volume, and quality parameters. After task execution is complete, the second PLC generates second operational data based on the collected task execution result data. This data primarily reflects the completion status of tasks at the target workstation and is an important basis for subsequent transfer decisions.
[0054] In some embodiments, the second PLC transmits the generated second business data to the first PLC via a predetermined communication protocol. This transmission process must ensure data integrity and timeliness. After receiving the second business data, the first PLC may further process and generate the first business data by combining it with data from other sources (e.g., production plans, inventory status, RFID information, etc.). The first PLC transmits the first business data to the MES system to determine the online transfer conditions. The MES evaluates whether the spool package meets the transfer conditions based on pre-configured rules and logic, and returns transfer instruction information to the first PLC.
[0055] Suppose a loading station for one yarn package is responsible for placing the yarn packages into trays. A second PLC controls the execution of the loading task at that station and is responsible for recording task execution result data such as the start and end times of each loading. After loading of a lot of yarn packages is complete, the second PLC generates second operational data based on this data, including information such as the total quantity of yarn packages in that lot, the loading time, and the lot number of the yarn packages, and transmits it to the first PLC. The MES combines this data with other data (e.g., production plan, inventory status) to determine whether to allow the yarn packages in that lot to be moved to the next production stage (e.g., weighing).
[0056] Thus, the second PLC directly generates second-party business data based on the task execution results, reducing errors in data transmission and conversion processes and improving data accuracy and reliability. Real-time task execution and monitoring, along with rapid data processing, enable the system to respond quickly to production changes and adjust transport strategies. Precise and accurate task execution result feedback allows the system to better coordinate production rhythms between each work station and optimize the entire production flow.
[0057] In the embodiments of this disclosure, the second business data is generated by the second PLC based on the execution results of tasks corresponding to the target work station and RFID information read by the RFID site corresponding to the target work station.
[0058] In some embodiments, the second PLC is responsible for monitoring and managing the actual production activities at the target work station, such as processing and detecting the yarn package. After the target work station completes a task (for example, completing the processing of the yarn package), the second PLC collects the results of the task, including information such as the task completion status, time taken, and pass / fail status. At the same time, the second PLC reads RFID information from the RFID site corresponding to the target work station, which is typically related to the yarn package currently being processed and includes the unique identifier of the yarn package, the production lot, and so on.
[0059] In some embodiments, the second PLC combines the task execution results and RFID information to generate second business data. This second business data not only reflects the physical state of the yarn package (e.g., location, lot) but also includes the specific circumstances and results of the task execution.
[0060] In some embodiments, the second PLC transmits the second business data to the first PLC or stores the second business data so that the first PLC can periodically retrieve it. If the first PLC confirms that communication with the MES is successful, it may further process this data and combine it with information from other sources (e.g., production plans, inventory status) to generate the first business data. The first PLC transmits the first business data to the MES to determine the online transfer conditions. The MES determines whether the spool package meets the transfer conditions based on pre-configured rules and logic and returns transfer instruction information to the first PLC.
[0061] Suppose there is an automated packaging station responsible for packaging processed yarn packages. A second PLC monitors the execution status of the packaging task at the said station. After packaging one yarn package is completed, the second PLC records information such as the completion time of the packaging task and packaging quality, and reads the RFID tag information of the yarn package from the corresponding RFID site (e.g., lot number, production date). The second PLC combines this information to generate second business data and transmits it to the first PLC. The first PLC further processes this data and transmits it to the MES for online transport decision-making. If the MES determines that the yarn package meets the transport conditions (e.g., packaging acceptable, below inventory), it transmits a "transport permission" instruction to the first PLC. After analyzing this information, the first PLC notifies the second PLC to start the conveyor and transport the yarn package to the subsequent storage station. By automatically identifying targets and acquiring related data using RFID, the identification process does not require human intervention, allowing it to operate in a variety of environments.
[0062] In this way, by directly collecting data from the task execution site and RFID site, the real-time and accuracy of the second operational data can be ensured, providing a reliable basis for subsequent transport decisions. By combining this with the MES's online decision-making function, intelligent decision-making regarding the transport conditions of the wound yarn packages can be achieved, improving the flexibility and responsiveness of production management. Close coordination between the first and second PLCs, and efficient communication between them and the MES, can ensure the smooth progress and efficient coordination of the entire production flow.
[0063] In some embodiments, the method for controlling the automatic transfer of the yarn package may further include the following steps.
[0064] During the process of transporting the spooled yarn package, the first PLC transmits task control commands to each second PLC based on the transport instruction information from the MES and the information read from each RFID site. Each second PLC then controls the automated equipment at the corresponding work station based on the corresponding command to perform the corresponding task.
[0065] Here, the first PLC not only receives the transport instruction information from the MES, but also transmits precise and accurate task control commands to each of the second PLCs based on this information and data read in real time from each RFID site.
[0066] In some embodiments, the first PLC first receives transfer station instruction information transmitted from the MES, which clearly indicates which winding packages are permitted to be transferred and the specific requirements for the transfer (e.g., target work station, priority, etc.). The first PLC analyzes the transfer instruction information, understands its meaning, and prepares the corresponding task control command.
[0067] In some embodiments, during the transfer of yarn packages, the first PLC continuously reads RFID information from each RFID site of the passing yarn packages. This information includes the unique identifier of the yarn package, the production lot, and the current location. By reading the RFID information in real time, the first PLC can track the real-time location and status of the yarn packages, ensuring the accuracy and timeliness of task control commands.
[0068] In some embodiments, the first PLC generates task control commands for each second PLC based on the transport instruction information from the MES and data read from the RFID site. These commands provide detailed information such as the task to be performed (e.g., starting a conveyor, adjusting equipment parameters, performing a quality inspection), the execution time, and the target work station. The first PLC transmits the task control commands to the corresponding second PLCs via a communication interface. After receiving the task control commands, each second PLC analyzes the command content and controls the automated equipment at the corresponding work station to perform the corresponding task in accordance with the command request. During the execution process, the second PLC may provide real-time feedback on the execution status to the first PLC so that the first PLC can monitor and adjust.
[0069] In this way, close cooperation between the first and second PLCs enables fully automated control of the yarn package transfer process, reducing manual intervention and improving production efficiency and accuracy. By reading RFID information and receiving MES instructions in real time, the system can respond quickly to production changes, adjust task control commands in a timely manner, and ensure the smooth progress of the production flow. Based on MES instructions and RFID information, the system can allocate and schedule resources (e.g., equipment, manpower, materials, etc.) more rationally, optimize the production flow, and improve resource utilization efficiency.
[0070] In some embodiments, as shown in Figure 3, the control system for the automatic transfer of the spool package includes six RFID sites, of which the first RFID site corresponds to the spool lifting area of the spool package, the second RFID site corresponds to the spinning wheel loading area, the third RFID site corresponds to the weight measurement area, the fourth RFID site corresponds to the bag covering area, the fifth RFID site corresponds to the visual inspection area, and the sixth RFID site corresponds to the palletizing area.
[0071] The automated transfer control system for yarn packages includes six RFID sites to enable tracking and management of the entire yarn package production flow. Each RFID site corresponds to one critical area in the yarn package production process, and the site layout is as follows:
[0072] The first RFID site is installed in the hoisting area of the yarn package and reads the RFID tag information as the yarn package falls from the production line to the yarn box or spinning wheel, recording the initial state and location of the yarn package.
[0073] The second RFID site is installed in the loading area of the spinning wheel and is used to read RFID information to verify the lot and quantity of the yarn packages before they are transferred to the conveyor spinning wheel and enter the next process.
[0074] The third RFID site is located in the weight measurement area and reads RFID information before and after weighing the yarn packages to ensure the accuracy of the weight measurement data and to associate it with the ID of the yarn package.
[0075] The fourth RFID site corresponds to the area where the bag is placed. When the weight measurement of the spool package is complete and the packaging is being prepared, the RFID information is read to record the packaging status and packaging time.
[0076] The fifth RFID site is located in the visual inspection area and reads RFID information before and after the visual inspection of the yarn packages, facilitating the tracking of inspection results and the handling of defective products.
[0077] The sixth RFID site is located in the palletizing area and is used to read RFID information and record the final storage location and time when all processes of the wound yarn package are completed and it is ready for palletizing.
[0078] Each yarn spool package is initially fitted with a unique RFID tag, which contains basic information such as the lot number, production date, and specifications of the yarn spool package.
[0079] In some embodiments, an RFID site refers to a physical location or device installed in the production flow for reading and writing RFID tag information.
[0080] In some embodiments, an RFID reader / writer is installed at each site and is responsible for reading and writing data to the RFID tags, ensuring real-time data updates and accuracy.
[0081] In some embodiments, the RFID tag is a tag that utilizes contactless automatic identification technology, communicating with a reader / writer via radio waves to enable data reading and writing.
[0082] In some embodiments, each RFID site is connected to a central control system (e.g., a PLC or MES) via a wired or wireless connection to enable real-time data transmission and sharing. Based on the data read by the RFID sites, the central control system generates task control commands and transmits them to the corresponding production equipment or robots to instruct them to perform the corresponding operations.
[0083] Assume that the production line for spooled yarn packages is equipped with the six RFID sites described above. When a batch of spooled yarn packages falls from the production line onto a yarn box or spinning wheel, the first RFID site reads its RFID tag information and transmits the data to the central control system. The spooled yarn package is then transferred to the spinning wheel, verified by the second RFID site, and then transported to the weighing area. In the weighing area, the third RFID site reads the RFID information before and after weighing to ensure the accuracy of the weighing data. The spooled yarn package is then transported to the bagging area for packaging, and the fourth RFID site records the packaging status and packaging time. The packaged spooled yarn packages are then transported to the visual inspection area for visual inspection, and the fifth RFID site reads the RFID information before and after inspection to track the inspection results. Finally, the approved spooled yarn packages are transported to the palletizing area for storage, and the sixth RFID site records their final storage location and storage time. Throughout the entire process, the central control system generates task control commands based on the data read by the RFID sites and transmits them to the corresponding production equipment or robots to instruct them to perform the corresponding operations.
[0084] Thus, RFID technology enables automatic identification and tracking of yarn packages, reducing manual intervention and errors, and improving production efficiency and accuracy. Each yarn package's RFID tag records important information about its production flow, facilitating rapid tracking and positioning in the event of problems. RFID technology allows for more accurate and efficient inventory management, providing real-time visibility into inventory status and location, and reducing inventory stagnation and waste. Combining RFID technology with a central control system makes the entire production process more automated and intelligent, reducing reliance on human labor.
[0085] In the embodiments of this disclosure, the installation of at least one RFID reader / writer at each RFID site is an important step in ensuring that the control system for the automated transfer of the yarn packages can accurately and efficiently read and record information on the yarn packages.
[0086] In some embodiments, the appropriate RFID reader / writer model is selected according to the specific needs of the RFID site (e.g., reading distance, reading speed, interference resistance, etc.). These RFID reader / writers should have good performance stability and high reading accuracy.
[0087] In some embodiments, selected RFID reader / writers are mounted in appropriate locations at each RFID site. Typically, these locations are chosen to be along the path through which the yarn package passes, ensuring that the RFID reader / writers can accurately read the information from the RFID tags on the yarn package. Securely and firmly mounting the RFID reader / writers prevents damage to the reader / writers or reading failures due to vibration or impact.
[0088] In some embodiments, each RFID site is equipped with a corresponding RFID reader / writer, which should be matched to the RFID site so that it can accurately read and process the information on the RFID tags. The reader / writer needs to be set to an appropriate reading frequency and power to ensure accurate reading of the RFID tags without affecting the normal operation of other equipment.
[0089] In an automated transfer control system for yarn packages at a chemical fiber factory, each RFID site is equipped with at least one RFID reader / writer. Taking a weight measurement area as an example, when a yarn package passes through the area, the RFID reader / writer in the weight measurement area accurately reads the information on the RFID tag on the yarn package. After the weight measurement is complete, a second PLC acquires the weight data corresponding to the yarn package and transmits the data to the first PLC. The first PLC compares the received data with a preset weight measurement standard and transmits the comparison result to the MES. The MES determines whether the yarn package meets the requirements, and if it does, transmits a "transfer permitted" transfer instruction to the first PLC. The first PLC transmits a "transfer permitted" transfer command to the second PLC, which controls the bagging work station to perform subsequent bagging and packaging operations. If the requirements are not met, it transmits a "transfer prohibited" transfer instruction to the first PLC. The first PLC transmits commands to the corresponding processing equipment to perform further processing or leveling on the spool package. Throughout the entire process, stable operation of the RFID site and reader / writer ensures data accuracy and real-time performance, providing strong support for a smooth production flow.
[0090] Thus, by providing at least one RFID reader / writer at each RFID site, the reading accuracy of RFID tags on yarn packages can be significantly improved, reducing the occurrence of missed readings and misreadings. Appropriate selection and installation of RFID reader / writers, as well as their placement, can improve the overall stability of the RFID system and ensure its reliability and accuracy during long-term operation. Accurate reading of RFID tags ensures accurate processing and recording of yarn packages at each step of the production flow, optimizing the production flow and improving production efficiency. The central control system can perform real-time analysis and processing based on the data read by the RFID sites, providing robust data support for production management and decision-making.
[0091] In some embodiments, as shown in Figure 4, each RFID site is provided with one main RFID reader / writer and at least one backup RFID reader / writer.
[0092] In some specific embodiments, a main RFID reader / writer is mounted at the core location of each RFID site. These RFID readers / writers should have high reading accuracy, long reading distance, and good interference resistance to ensure stable and accurate reading of the RFID tag information in the yarn package. The main RFID reader / writer should work closely with other reader / writers, transmitting data using pre-configured communication protocols and parameters to ensure real-time and accurate data.
[0093] In some embodiments, one or more backup RFID reader / writers are provided in the vicinity of the main RFID reader / writer or within an area that can be covered by the same reader / writer. These backup RFID reader / writers must have the same model number as the main RFID reader / writer or be compatible with the main RFID reader / writer so that they can be immediately replaced if the main RFID reader / writer fails. The backup RFID reader / writers are normally in standby mode and do not participate in normal reading operations. However, if the main RFID reader / writer fails, the system can switch to the backup RFID reader / writer automatically or manually, thereby ensuring the normal operation of the RFID site.
[0094] In some specific embodiments, the first PLC or MES is equipped with a monitoring module for real-time monitoring of the operating status of the main and backup reader / writers at each RFID site. Upon detecting a failure or performance degradation of the main reader / writer, an alarm is immediately triggered to activate the switching mechanism. The switching logic and parameters are configured to ensure that data continuity and accuracy are not affected during the switching process between the main and backup reader / writers.
[0095] As an example, in an automated transfer control system for yarn packages at a chemical fiber factory, each RFID site is equipped with a main reader / writer and a backup reader / writer. When a yarn package passes through the weight measurement area, the main reader / writer reads the information from the RFID tag on the yarn package and transmits the data to the MES for processing. If the main reader / writer fails to operate properly, the system automatically switches to the backup reader / writer to perform the reading operation. Furthermore, a monitoring module in the MES monitors the status of the main and backup reader / writers in real time and issues alarms and switching commands as needed. This installation method can ensure the continuity and accuracy of the RFID sites and improve the reliability and stability of the entire production flow.
[0096] By adding backup RFID reader / writers, the main reader / writer can be quickly replaced in the event of a failure, preventing interruptions to the production flow and data loss. The presence of backup reader / writers also allows for a sharing of the operational load on the main reader / writer, reducing the risk of performance degradation and failure due to prolonged continuous operation. The monitoring module monitors the status of the reader / writers in real time, enabling timely detection and resolution of potential problems, reducing maintenance costs and improving maintenance efficiency.
[0097] 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.
[0098] In some embodiments, the transfer instruction information is information that indicates whether or not the spooled yarn package in the production line is permitted to be 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."
[0099] 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. Internally, 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 to represent a specific operating state or attribute.
[0100] 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 is permitted to 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 may notify on-site staff to inspect and process the package by triggering the corresponding alarm mechanism.
[0101] 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.
[0102] 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 pre-set 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 transfer 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.
[0103] Thus, by analyzing the initial 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 operating efficiency of the production line.
[0104] 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.
[0105] 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 unit, data coder, etc.
[0106] Here, the data storage area is a specific area within the first PLC for storing data.
[0107] 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.
[0108] 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 predetermined 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 conforms to a pre-configured data storage format, thus facilitating subsequent processing and transmission. 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.
[0109] 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.
