Various details of the embodiments of the present disclosure are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following.

[0025] The terms "first", "second", and "third", etc. in the description of the embodiments, claims, and the above drawings of the present disclosure are used to distinguish similar objects and do not necessarily describe a specific order or sequence. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0026] Before introducing the technical solutions of the embodiments of the present disclosure, further explanations are made on the technical terms that may be used in the present disclosure:

[0027] MES: A software system for monitoring and managing manufacturing processes, capable of collecting, processing, and analyzing production data in real time to optimize production plans and resource allocation.

[0028] PLC: An industrial digital computer used to control automated equipment such as mechanical devices and robots on the production line. It can perform logical operations and processing on input signals according to preset programs and output control signals to control the operation of the equipment.

[0029] RFID: A communication technology that can identify specific targets and read and write relevant data through radio signals without the need to establish mechanical or optical contact between the identification system and the specific target.

[0030] RFID station: A physical location or device equipped with RFID readers for reading and recording RFID tag information passing through that location.

[0031] Business data: Data related to business generated during the manufacturing process, such as equipment status, product quantity, production progress, etc. This data is the basis for decision-making and control by MES and PLC.

[0032] Passing station instruction information (also known as passing station command): Instructions and parameter information generated by MES based on business data analysis to guide equipment to perform passing station tasks.

[0033] Figure 1 The schematic diagram of the automatic passing station control system for silk ingots is shown, as Figure 1 shown, the automatic passing station control system for silk ingots includes MES, a first PLC, and multiple second PLCs. The multiple 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. Among them, the second PLC is mainly responsible for collecting and processing the real-time business data of the target work station and providing it for the first PLC to use. The first PLC is responsible for interacting with the second PLC to obtain the second business data from the second PLC; the first PLC is also responsible for interacting with MES, sending the first business data to MES, and receiving the passing station instruction information issued by MES based on this first business data, and then notifying the second PLC to execute the passing station instruction information for the target work station.

[0034] In some embodiments, MES is used to determine passing station instruction information for the target work station based on the first business data sent by the first PLC and return the passing station instruction information to the first PLC.

[0035] In some embodiments, the first PLC is used to obtain the first business data for the target work station according to the second business data for the target work station obtained from the second PLC.

[0036] In some embodiments, each second PLC is used to acquire and store second service data of a target work station controlled thereby.

[0037] Here, the first service data is a data set collected and processed by the first PLC, including information such as the real-time status of the target work station, the processing progress of the silk ingot, the silk ingot quality inspection result, and the request type. These data are of great significance for monitoring the operation status of the production line and making decisions on whether to allow passing through the station.

[0038] Here, the second service data is a data set collected and processed by the second PLC, including information such as the real-time status of the target work station, the processing progress of the silk ingot, the silk ingot quality inspection result, and the silk ingot barcode. These data are of great significance for monitoring the operation status of the production line.

[0039] In the automatic silk ingot passing-through station control system according to the embodiments of the present disclosure, through real-time communication and data processing among the MES, the first PLC, and the second PLC, the MES can monitor the status of each work station in real time and make adjustments and optimizations as needed. Through the above-mentioned automatic control, manual intervention is reduced, the efficiency and accuracy of the silk ingot passing through the station are improved; material waste and downtime caused by human errors are reduced, and the production cost is lowered. Through the above-mentioned automatic control, the stability and consistency of the silk ingot during the passing-through process are ensured, which helps to improve the overall production rhythm and efficiency. By using the first PLC as the intermediate layer between the MES and multiple second PLCs, the automatic silk ingot passing-through station control system has significant advantages in aspects such as centralized management, data integration, reducing the burden on the MES, enhancing system scalability, improving security and stability, and simplifying the network structure.

[0040] If the MES directly communicates with multiple second PLCs, it will need to process a large amount of real-time data and requests, which may increase the burden on the MES and affect its performance. By using the first PLC as the intermediate layer, the MES only needs to communicate with the first PLC, thus reducing its processing burden. In the absence of the first PLC as the intermediate layer, the MES needs to establish direct communication connections with each second PLC, which will make the network structure complex and difficult to manage. By using the first PLC for relaying, the network structure can be greatly simplified, making the entire communication process clearer and more orderly. The first PLC can serve as a security barrier to verify and filter data from the second PLC, preventing malicious data or incorrect data from entering the MES system. At the same time, the redundancy and fault tolerance mechanisms of the first PLC can improve the stability and reliability of the system, ensuring the normal operation of the production line even when some equipment fails.

[0041] As the production line expands and upgrades, it may be necessary to add more second PLCs. If MES communicates directly with each second PLC, then corresponding configuration and modification of MES are required for each expansion. However, by using the first PLC as an intermediate layer, only the support for the new second PLC needs to be added in the first PLC, without modifying the configuration of MES. The first PLC can centrally receive business data from multiple second PLCs and perform unified processing and analysis. This method makes the control of the entire production line more centralized and orderly, reducing the complexity and chaos of MES directly communicating with multiple second PLCs. The first PLC can integrate data from different second PLCs to form a more comprehensive production view, which enables MES to make decisions based on more comprehensive data, thereby optimizing production plans and resource allocation. At the same time, the first PLC can also preprocess and filter data, reducing the amount of data transmitted to MES and improving communication efficiency.

[0042] Embodiments of the present disclosure provide a method for automatically controlling the passing of silk spindles through stations. Figure 2 FIG. is a schematic flowchart of the method for automatically controlling the passing of silk spindles through stations according to embodiments of the present disclosure. The method for automatically controlling the passing of silk spindles through stations can be applied to a device for automatically controlling the passing of silk spindles through stations, which is located on an electronic device, and the electronic device is applied to a system for automatically controlling the passing of silk spindles through stations. The electronic device includes, but is not limited to, fixed devices and / or mobile devices. For example, fixed devices include, but are not limited to, servers, and the server can be a cloud server or a general server. For example, mobile devices include, but are not limited to: mobile phones, tablet computers, laptop computers, etc. In some possible implementation manners, the method for automatically controlling the passing of silk spindles through stations can also be implemented by a processor calling computer-readable instructions stored in a memory. As Figure 2 shown, the method for automatically controlling the passing of silk spindles through stations includes:

[0043] S201: When the control button of the first PLC is in the online mode and the communication between the first PLC and MES is normal, the first PLC obtains second business data of the target station from the second PLC, and sends the first business data to MES, so that MES performs judgment processing on the online passing condition based on the first business data, and returns passing instruction information to the first PLC; wherein, the first business data is generated by the first PLC according to the second business data and the RFID information read from the RFID station corresponding to the target station;

[0044] S202: When the first PLC receives the passing instruction information, it sends the parsing result of the passing instruction information to the second PLC, so that the second PLC controls the target station to perform the silk spindle passing task based on the parsing result.

[0045] In some embodiments, the control button is a physical switch or knob for controlling the working mode of the first PLC. It is used to switch the working mode of the first PLC (such as the online mode or the offline mode). The offline mode is a specific position or mark on the control button. When the button is switched to this position, it indicates that the offline mode is selected, which is used to actively interrupt the communication with the MES. The online mode is a specific position or mark on the control button. When the button is switched to this position, it indicates that the online mode is selected, which is used when hoping to maintain communication with the MES.

[0046] In some embodiments, check whether the control button of the first PLC is in the online mode to ensure that the system is in an operable state. Then, check whether the communication between the first PLC and the MES is normal through the network communication protocol.

[0047] In some embodiments, after confirming that the communication is normal, the first PLC obtains the second service data of the target station from the second PLC through a preset communication interface. These data may include information such as the current status, position, production batch of the silk ingot, etc.

[0048] In some embodiments, the first PLC reads the RFID information on the RFID site corresponding to the target station. This information usually contains key data such as the unique identifier and production batch of the silk ingot. The first PLC combines the second service data with the RFID information to generate the first service data, which more comprehensively and accurately reflects the current status of the silk ingot and the tasks to be performed.

[0049] In some embodiments, the first PLC sends the first service data to the MES. The MES performs the judgment and processing of the online passing condition according to the preset service logic and rules (such as production plan, inventory status, equipment status, etc.). The MES generates passing instruction information according to the judgment result and returns it to the first PLC through the communication interface. The passing instruction information clearly indicates whether the silk ingot is allowed to pass the station, that is, whether it can continue to the next production link.

[0050] In some embodiments, after receiving the passing instruction information, the first PLC performs parsing processing to confirm whether it is "permitted to pass the station" or "forbidden to pass the station". In the case where the parsing result is permitted to pass the station, notify the passing equipment or directly control the passing equipment to transfer the silk ingot processed at the target station to the next station of the target station; in the case where the parsing result is forbidden to pass the station, notify the passing equipment or directly control the passing equipment to prohibit the target station from performing the silk ingot passing task, and re-send the second service data for the target station. If it is "forbidden to pass the station", it may also trigger an alarm mechanism to notify the operator or perform other corresponding processing.

[0051] Here, the in-line equipment refers to the automated equipment used on the production line to transfer materials (such as silk ingots) between different workstations, such as conveyor belts, manipulators, automatic transfer carts, etc. The above is only an exemplary description and does not limit all possible equipment included in the in-line equipment. Here, an exhaustive list is not made.

[0052] In some embodiments, the first PLC obtains the second service data of each workstation from each second PLC and generates the first service data for each workstation. These first service data contain the status of all relevant workstations and the operation information that needs to be performed. The MES analyzes the first service data to determine the in-line instruction information of the target workstation (i.e., the workstation that currently needs to perform the silk ingot in-line task). The in-line instruction information includes permission to pass or prohibition to pass. Among them, when the in-line instruction information is permission to pass, it may also include parameters such as the specific time of passing, the target position, and the speed. The MES sends the generated in-line instruction information to the first PLC through the network or other communication methods such as the Management Interface (MI).

[0053] In some embodiments, after receiving the in-line instruction information from the MES, the first PLC performs parsing and processing to extract specific control instructions and parameters. After the first PLC finishes parsing, it sends the parsing result (i.e., specific control instructions and parameters) to the second PLC corresponding to the target workstation through the communication interface or communication protocol. After receiving the parsing result, the second PLC controls the in-line equipment such as the mechanical device or robot of the target workstation to perform the silk ingot in-line task according to the control instructions and parameters in the parsing result.

[0054] In some embodiments, at system startup, the communication protocol and parameters between the first PLC and the second PLC are configured to ensure stable communication between the two. The connection between the first PLC and the MES is configured to ensure that the first PLC can send the first business data to the MES and receive the passing station indication information returned by the MES. The first PLC actively obtains the second business data of the target station (such as the current working state, the number of yarn packages to be processed, the processing time, etc.) from the second PLC corresponding to the target station. After the first PLC obtains the second business data, according to a preset algorithm or logic, these data are converted into the first business data (such as whether the passing station condition is met, the estimated passing station time, etc.). If the connection between the first PLC and the MES is disconnected due to reasons (such as network failure, MES maintenance, etc.), the first PLC will automatically switch to the offline working mode. In this mode, the first PLC will record the first business data and send the passing station indication information (such as a "permitted to pass" signal) to the second PLC. After receiving the passing station indication information, the second PLC will control the target station to perform the yarn package passing station task, including moving the yarn package to the next station and updating the status information, etc. Once the connection between the first PLC and the MES is restored, the system can automatically synchronize the data and adjust the subsequent operations according to the latest instructions of the MES.

[0055] For example, assume that there are multiple stations on the production line, and each station is responsible for different processing tasks. The first PLC regularly obtains the second business data of the current station from the second PLC. When the yarn package at a certain station (such as the weighing station) is processed and needs to enter the next process. At this time, if the MES is temporarily unavailable, the first PLC will send the passing station indication information of "permitted to pass" to the second PLC on behalf of the MES. Subsequently, the second PLC sends an instruction to the passing station equipment (such as a conveyor belt or a manipulator) to transfer the processed yarn package to the next station (such as the winding diameter measurement station) for subsequent processing.

[0056] The main types of yarn packages involved in the solution of the embodiments of the present disclosure may include one or more of partially oriented yarns (POY), fully drawn yarns (FDY), draw textured yarns (DTY) (or called low elastic yarns), etc. For example, the types of yarns may specifically include polyester partially oriented yarns, polyester fully drawn yarns, polyester drawn yarns, polyester draw textured yarns, polyester staple fiber (PSF), etc.

[0057] The technical solution of the embodiment of the present disclosure enables the MES to monitor the status of each work station in real time and adjust and optimize the passing strategy as needed through real-time communication and data processing among the MES, the first PLC, and multiple second PLCs. Combining the RFID technology and the real-time data of the MES system ensures the accurate judgment of passing conditions and reduces production problems caused by human errors. Through automatic control, manual intervention is reduced, and the accuracy and efficiency of the silk ingot passing are improved. The system can flexibly adjust the passing strategy according to the real-time instructions of the MES to adapt to different production requirements. The real-time collection, processing, and feedback of production data provide strong data support for the production management of silk ingots.

[0058] In the embodiment of the present disclosure, the automatic passing control method for the silk ingot further includes: when the first PLC detects that the control button corresponding to the first PLC is switched to the offline mode, it is determined that the first PLC is disconnected from the MES.

[0059] In some embodiments, the first PLC continuously monitors the status of the control button directly connected to it. This button is usually installed on the control panel, allowing the operator to manually switch the working mode of the first PLC. When it is detected that the control button is switched to the "offline mode" position, the first PLC immediately records this event and considers that the connection with the MES has been or is about to be disconnected. It should be noted that this detection method mainly relies on hardware signals (such as the switch state of the button), so it is immediate and reliable. After determining the offline mode, the first PLC will obtain the second service data of the target work station from the second PLC according to the established process and convert it into the first service data. Based on the processed first service data, the first PLC will decide whether to send a passing instruction message to the second PLC to control the passing task of the silk ingot. Generally, the first PLC will send a passing instruction message of "permission to pass" to the second PLC. The system should have the ability to handle various abnormal situations and automatically synchronize data or restore the connection with the MES when the conditions are restored.

[0060] Taking the automatic packaging line in the chemical fiber industry as an example, due to a network failure, the MES is temporarily unable to communicate with the first PLC. At this time, the operator can walk to the control panel where the first PLC is located and switch the control button to the "offline mode". After the first PLC detects this change, it will automatically determine that the connection with the MES has been disconnected and immediately start the passing control process in the offline mode. Subsequently, the first PLC will send a passing instruction message of "permission to pass" to the second PLC to ensure that the silk ingot can move smoothly from the current work station to the next work station.

[0061] Thus, by introducing control buttons, it allows operators to directly intervene in the production process under specific circumstances, improving the flexibility of the system and its ability to respond to emergencies. The status detection of the control buttons provides an intuitive indication of the connection status between the first PLC and MES, helping to promptly detect and handle connection problems, thereby enhancing the reliability of the system. In the event that MES is unavailable, the operator can simply rotate the control button to switch the first PLC to the offline mode, enabling the system to continue performing the in-station tasks, simplifying the operation process and reducing downtime.

[0062] In some embodiments, the second service data is generated by the second PLC based on the task execution results corresponding to the target station.

[0063] Here, the task execution results refer to the result information reflecting the task completion situation generated after the target station executes a specific production task, including but not limited to task completion status, elapsed time, quality inspection results, etc.

[0064] Here, the second service data is a data set generated by the second PLC based on the task execution results and used for subsequent processing (such as in-station judgment).

[0065] In some embodiments, the second PLC serves as the direct control unit of the target station and is responsible for executing and monitoring the production tasks at that station. These tasks may include processing, inspection, packaging of silk ingots, etc. During the task execution, the second PLC will collect relevant data of the task execution in real time, such as start time, end time, execution status (success, failure, pause, etc.), production volume, quality parameters, etc. When the task is completed, the second PLC generates the second service data based on the collected task execution result data. These data mainly reflect the completion situation of the tasks at the target station and are an important basis for subsequent in-station judgment.

[0066] In some embodiments, the second PLC sends the generated second service data to the first PLC through a predetermined communication protocol. This transmission process needs to ensure the integrity and timeliness of the data. After receiving the second service data, the first PLC may combine data from other sources (such as production plan, inventory status, RFID information, etc.) to further process and generate the first service data. The first PLC sends the first service data to the MES system for in-station condition judgment. MES evaluates whether the silk ingot meets the in-station conditions according to the preset rules and logic and returns the in-station indication information to the first PLC.

[0067] Suppose there is a spool loading station responsible for placing spools onto trays. The second PLC is responsible for controlling the execution of the loading tasks at this station and recording task execution result data such as the start time and end time of each loading. After a batch of spools has been loaded, the second PLC generates second business data based on this data, including information such as the total number of spools in this batch, the loading time consumption, and the spool batch number, and sends it to the first PLC. The MES combines other data (such as production plans and inventory status) to decide whether to allow this batch of spools to pass through to the next production process (such as weighing).

[0068] In this way, the second PLC directly generates second business data based on task execution results, reducing errors in the data transmission and conversion processes, and improving the accuracy and reliability of the data. Real-time task execution monitoring and fast data processing enable the system to quickly respond to production changes and adjust the passing strategy. Through accurate feedback of task execution results, the system can better coordinate the production rhythms between each station and optimize the overall production process.

[0069] In the embodiments of the present disclosure, the second business data is generated by the second PLC based on the task execution results corresponding to the target station and the RFID information read from the RFID station corresponding to the target station.

[0070] In some embodiments, the second PLC is responsible for monitoring and managing the actual production activities of the target station, such as the processing and inspection of spools. When the target station completes a task (such as the spool processing is completed), the second PLC will collect the execution results of this task, including information such as the task completion status, time consumption, and whether it is qualified. At the same time, the second PLC will read RFID information from the RFID station corresponding to the target station. This information is usually associated with the currently processed spool and includes the unique identifier of the spool, the production batch, etc.

[0071] In some embodiments, the second PLC combines the task execution results and RFID information to generate second business data. These second business data not only reflect the physical state of the spool (such as location, batch), but also contain the specific situation and results of task execution.

[0072] In some embodiments, the second PLC sends the second business data to the first PLC, or stores the second business data for the first PLC to obtain regularly. When the first PLC confirms normal communication with the MES, it further processes this data and may combine information from other sources (such as production plans, inventory status, etc.) to generate first business data. The first PLC sends the first business data to the MES for judgment of the online passing conditions. The MES judges whether the spool meets the passing conditions according to preset rules and logics, and returns passing instruction information to the first PLC.

[0073] Suppose there is an automatic packaging station responsible for packaging the processed silk ingots. The second PLC monitors the execution of the packaging tasks at this station. When a package of silk ingots is completely packaged, the second PLC will record information such as the completion time and packaging quality of the packaging task, and read the RFID tag information (such as batch number, production date, etc.) of this package of silk ingots from the corresponding RFID station. Combining this information, the second PLC generates the second business data and sends it to the first PLC. The first PLC further processes this data and sends it to the MES for online passing judgment. If the MES determines that this package of silk ingots meets the passing conditions (such as qualified packaging, sufficient inventory, etc.), it will send an instruction message of "permission to pass" to the first PLC. After parsing this information, the first PLC notifies the second PLC to start the conveyor belt to transport this package of silk ingots to the subsequent warehousing station. By automatically identifying the target object through RFID and obtaining relevant data, the identification work does not require manual intervention and can work in various environments.

[0074] In this way, by directly collecting data from the task execution site and RFID stations, the timeliness and accuracy of the second business data are ensured, providing a reliable basis for subsequent passing judgment. Combining with the online judgment function of the MES, an intelligent decision-making for the passing conditions of silk ingots is realized, improving the flexibility and response speed of production management. The close cooperation between the first PLC and the second PLC, as well as their effective communication with the MES, ensure the smooth progress and efficient coordination of the entire production process.

[0075] In some embodiments, the automatic passing control method for silk ingots may further include:

[0076] During the passing of silk ingots, the first PLC sends task control instructions to each second PLC according to the passing instruction information from the MES and the information read from each RFID station, so that each second PLC controls the automation equipment at the corresponding station to execute the corresponding tasks according to the corresponding instructions.

[0077] Here, the first PLC is not only responsible for receiving the passing instruction information from the MES, but also sends accurate task control instructions to each second PLC according to this information and the data read in real time from each RFID station.

[0078] In some embodiments, the first PLC first receives the passing instruction information sent by the MES, which clearly indicates which silk ingots can pass and the specific requirements for passing (such as target station, priority, etc.). The first PLC parses the passing instruction information, understands its meaning, and prepares the corresponding task control instructions.

[0079] In some embodiments, during the process of the silk ingot passing through the station, the first PLC continuously reads the RFID information of the passing silk ingots from each RFID station. This information includes the unique identifier, production batch, current position, etc. of the silk ingot. By reading the RFID information in real time, the first PLC can track the real-time position and status of the silk ingot, ensuring the accuracy and timeliness of the task control instructions.

[0080] In some embodiments, based on the passing instruction information from the MES and the data read from the RFID stations, the first PLC generates task control instructions for each second PLC. These instructions detail the tasks to be executed (such as starting the conveyor belt, adjusting equipment parameters, performing quality inspections, etc.), the execution time, the target workstations, and other information. The first PLC sends the task control instructions to the corresponding second PLC through the communication interface. After receiving the task control instructions, each second PLC parses the instruction content and controls the automated equipment at the corresponding workstations to execute the corresponding tasks according to the instruction requirements. During the execution process, the second PLC may feedback the execution status to the first PLC in real time for the first PLC to monitor and adjust.

[0081] In this way, through the close cooperation between the first PLC and the second PLC, a comprehensive automated control of the silk ingot passing through the station process is achieved, reducing manual intervention, improving production efficiency and accuracy. Reading the RFID information in real time and receiving the MES instructions enable the system to quickly respond to production changes, timely adjust the task control instructions, and ensure the smooth progress of the production process. According to the MES instructions and RFID information, the system can more reasonably allocate and schedule resources (such as equipment, manpower, materials, etc.), optimize the production process, and improve resource utilization efficiency.

[0082] In some embodiments, as Figure 3 shown, the automatic silk ingot passing through the station control system includes six RFID stations. Among them, the first RFID station corresponds to the silk ingot winding area, the second RFID station corresponds to the silk cart on-line area, the third RFID station corresponds to the weighing area, the fourth RFID station corresponds to the bagging area, the fifth RFID station corresponds to the external inspection area, and the sixth RFID station corresponds to the palletizing area.

[0083] In the automatic silk ingot passing through the station control system, six RFID stations are set up to achieve the whole-process tracking and management of the silk ingot in the production process. Each RFID station corresponds to a key area in the silk ingot production process, and the station layout is as follows:

[0084] The first RFID station is installed in the silk ingot winding area, used to read the RFID tag information of the silk ingot when it falls from the production line into the silk box or silk cart, and record the initial state and position of the silk ingot.

[0085] The second RFID station is set in the area where the silk bobbins are loaded onto the transport carts. When the silk bobbins are transferred to the transport carts and ready to enter the next process, the RFID information is read to confirm the batch number and quantity of the silk bobbins.

[0086] The third RFID station is located in the weighing area and is used to read the RFID information before and after the silk bobbins are weighed, ensuring the accuracy of the weighing data and associating it with the identity of the silk bobbins.

[0087] The fourth RFID station corresponds to the bagging area. When the silk bobbins are weighed and ready for bagging and packaging, the RFID information is read to record the packaging status and packaging time.

[0088] The fifth RFID station is set in the external inspection area and is used to read the RFID information before and after the appearance inspection of the silk bobbins, facilitating the tracking of inspection results and the handling of non-conforming products.

[0089] The sixth RFID station is located in the palletizing area. When the silk bobbins complete all processes and are ready for palletizing and warehousing, the RFID information is read to record the final storage location and the warehousing time.

[0090] Among them, each silk bobbin is assigned a unique RFID tag at the initial stage of production, and the tag contains basic information such as the batch number, production date, and specifications of the silk bobbin.

[0091] In some embodiments, the RFID station refers to a physical location or device set in the production process for reading and writing RFID tag information.

[0092] In some embodiments, RFID readers / writers are installed at each station, responsible for reading and writing data in the RFID tags to ensure the real-time update and accuracy of the data.

[0093] In some embodiments, the RFID tag is a non-contact automatic identification technology tag that communicates with the reader / writer through radio waves to achieve data reading and writing.

[0094] In some embodiments, each RFID station is connected to the central control system (such as PLC or MES) by wired or wireless means to achieve real-time data transmission and sharing. The central control system generates task control instructions based on the data read by the RFID stations and sends them to the corresponding production equipment or robots to guide them to perform corresponding operations.

[0095] Suppose the above six RFID stations are set up in the silk ingot production line. When a batch of silk ingots fall from the production line into the silk box or the silk cart, the first RFID station reads the RFID tag information and sends the data to the central control system. Subsequently, the silk ingots are transferred to the silk cart and enter the weighing area after being confirmed by the second RFID station. In the weighing area, the third RFID station reads the RFID information before and after weighing to ensure the accuracy of the weighing data. After that, the silk ingots enter the bagging area for packaging, and the fourth RFID station records the packaging status and packaging time. The packaged silk ingots enter the external inspection area for appearance inspection, and the fifth RFID station reads the RFID information before and after inspection to track the inspection results. Finally, the qualified silk ingots enter the stacking area to prepare for warehousing, and the sixth RFID station records their final storage location and warehousing time. Throughout the process, the central control system generates task control instructions based on the data read by the RFID stations and sends them to the corresponding production equipment or robots to guide them to perform the corresponding operations.

[0096] In this way, the automatic identification and tracking of silk ingots are realized through RFID technology, reducing manual intervention and errors, and improving production efficiency and accuracy. The RFID tag of each silk ingot records the key information in its production process, facilitating quick traceability and positioning in case of problems. RFID technology makes inventory management more precise and efficient, enabling real-time monitoring of inventory status and location, and reducing inventory backlog and waste. Combining RFID technology with the central control system makes the entire production process more automated and intelligent, reducing the dependence on manual labor.

[0097] In the embodiments of the present disclosure, setting at least one RFID reader at each RFID station is a key step to ensure that the automatic passing control system of silk ingots can accurately and efficiently read and record silk ingot information.

[0098] In some embodiments, according to the specific requirements of the RFID station (such as reading distance, reading speed, anti-interference ability, etc.), a suitable RFID reader model is selected. These RFID readers should have good performance stability and high reading accuracy.

[0099] In some embodiments, at each RFID station, the selected RFID reader is installed in a suitable position. Generally, these positions should be selected on the necessary paths where the silk ingots pass through to ensure that the RFID reader can accurately read the RFID tag information on the silk ingots. The installation of the RFID reader should be firm and reliable to avoid damage or reading failure of the reader caused by vibration or collision.

[0100] In some embodiments, a corresponding RFID reader / writer is configured for each RFID station. The reader / writer should match the RFID station and be capable of accurately reading and processing the information in the RFID tag. The reader / writer should be set with appropriate reading frequencies and powers to ensure accurate reading of the RFID tag without affecting the normal operation of other devices.

[0101] In the automatic passing station control system of silk spindles in a chemical fiber factory, at least one RFID reader / writer is set at each RFID station. Taking the weighing area as an example, when a silk spindle passes through this area, the RFID reader / writer in the weighing area accurately reads the RFID tag information on the silk spindle. After weighing, the second PLC obtains the weight data of the corresponding silk spindle and transmits the data to the first PLC. The first PLC compares the received data with the preset weighing standard and sends the comparison result to the MES. The MES determines whether the silk spindle meets the requirements. If it meets the requirements, it sends a passing instruction message of "permission to pass" to the first PLC. The first PLC sends the passing instruction of "permission to pass" to the second PLC, so that the second PLC controls the bagging station to perform subsequent bagging and packaging operations. If it does not meet the requirements, it sends a passing instruction message of "prohibited from passing" to the first PLC. The first PLC sends instructions to the corresponding processing equipment to further process or downgrade the silk spindle. Throughout the process, the stable operation of the RFID station and the reader / writer ensures the accuracy and real-time nature of the data, providing strong guarantee for the smooth progress of the production process.

[0102] In this way, setting at least one RFID reader / writer at each RFID station can greatly improve the reading accuracy rate of the RFID tags of silk spindles and reduce the occurrence of missed readings and misreadings. Through reasonable selection and installation of RFID reader / writers, as well as the configuration of RFID reader / writers, the stability of the entire RFID system can be enhanced, ensuring its reliability and accuracy during long-term operation. Accurate reading of RFID tags can ensure that each step of the silk spindle in the production process is correctly processed and recorded, thereby optimizing the production process and improving production efficiency. The central control system can perform real-time analysis and processing based on the data read by the RFID stations, providing strong data support for production management and decision-making.

[0103] In some embodiments, as Figure 4 shown, a main RFID reader / writer and at least one standby RFID reader / writer are set at each RFID station.

[0104] In some specific embodiments, a main RFID reader / writer is installed at the core position of each RFID site. These RFID reading and writing devices should have high reading accuracy, long reading distance, and good anti-interference ability to ensure that the RFID tag information on the silk ingots can be read stably and accurately. The main RFID reader / writer should cooperate closely with the reader / writer, and data transmission should be carried out through preset communication protocols and parameters to ensure the real-time and accuracy of data.

[0105] In some specific embodiments, one or more backup RFID reader / writers are added near the main RFID reader / writer or within the coverage range of the same reader / writer. These backup RFID reader / writers should be of the same model or compatible with the main RFID reader / writer so that they can be seamlessly replaced when the main RFID reader / writer fails. The backup RFID reader / writers are usually in a standby state and do not participate in normal reading operations. However, when the main RFID reader / writer has problems, the system can automatically or manually switch to the backup RFID reader / writer to ensure the normal operation of the RFID site.

[0106] In some specific embodiments, a monitoring module is set in the first PLC or MES to monitor the working status of the main and backup reader / writers at each RFID site in real time. Once a failure or performance degradation of the main reader / writer is detected, an alarm is immediately triggered and the switching mechanism is started. The switching logic and parameters are configured to ensure that the continuity and accuracy of data are not affected during the switching process between the main reader / writer and the backup reader / writer.

[0107] Taking the automatic passing station control system of silk ingots in a chemical fiber factory as an example, a main reader / writer and a backup reader / writer are installed at each RFID site. When the silk ingot passes through the weighing area, the main reader / writer is responsible for reading the RFID tag information on the silk ingot and transmitting the data to the MES for processing. If the main reader / writer fails to work properly due to a fault, the system will automatically switch to the backup reader / writer for reading operations. At the same time, the monitoring module in the MES will monitor the status of the main and backup reader / writers in real time and issue alarm and switching instructions when necessary. This setting method ensures the continuity and accuracy of the RFID site and improves the reliability and stability of the entire production process.

[0108] In this way, by adding a backup RFID reader / writer, it can be quickly replaced when the main reader / writer fails, avoiding the interruption of the production process and data loss. The existence of the backup reader / writer can share the working pressure of the main reader / writer, reducing the performance degradation and failure risk caused by long-term continuous work. By monitoring the status of the reader / writer in real time through the monitoring module, potential problems can be detected and processed in a timely manner, reducing the maintenance cost and improving the maintenance efficiency.

[0109] In the embodiments of the present disclosure, the judgment and processing of the online passing conditions may include: determining whether the spindles at the target station meet the passing conditions based on the target string data corresponding to the target station, where the target string data is obtained by the MES parsing the first service data; if the passing conditions are met, determining that the passing instruction information is permission to pass; if the passing conditions are not met, determining that the passing instruction information is prohibited from passing.

[0110] In some embodiments, the passing instruction information is used to indicate whether the spindles on the production line can continue to be transferred to the next station for processing. According to the judgment result of the passing conditions, the passing instruction information can be "permission to pass" or "prohibited from passing".

[0111] In some embodiments, the MES first receives the first service data sent by the first PLC. These data usually include the status information of the target station on the production line, the processing progress of the spindles, the quality inspection results, the number of times of requesting to pass, etc. There is a special data parsing module set inside the MES for parsing the received first service data to extract the target string data corresponding to the target station. These target string data may be encoded and represent specific working states or attributes.

[0112] In some embodiments, based on the parsed target string data, the MES further compares and analyzes with the preset passing conditions. These passing conditions may include whether the processing quality of the spindles meets the standard, whether all the processing tasks at the current station have been completed, whether there are equipment failures or production anomalies, etc. If the spindles at the target station meet all the preset passing conditions, the MES determines that the passing instruction information is "permission to pass", indicating that the spindles can be safely transferred to the next station for further processing. If the spindles at the target station do not meet any of the passing conditions, the MES determines that the passing instruction information is "prohibited from passing" and may trigger a corresponding alarm mechanism to notify the on-site personnel for inspection and handling.

[0113] In some embodiments, the MES takes the judgment result (permission to pass or prohibited from passing) as the passing instruction information and sends it to the second PLC or other relevant control devices through the communication interface. These passing devices execute the corresponding control logic according to the received passing instruction information, such as starting or stopping the transfer action of the spindles.

[0114] Taking the automatic packaging line in the chemical fiber industry as an example, when the first PLC detects that the processing of a silk ingot at a certain station (such as the weighing station) is completed, it will send the first business data containing the status information of this station to the MES. After receiving the data, the MES first parses out the target string data (such as the QR code and weight information of the silk ingot for this passing station request), and then compares it with the preset passing conditions (such as whether the weight of the silk ingot of this specification is within the allowable range, Grade A: within the allowable range, Grade B: light weight, Grade C: heavy weight). If the quality grade of the silk ingot is Grade A, the MES determines that the passing instruction information is "permitted to pass" and notifies the second PLC to start the transfer action of the silk ingot; if the quality grade of the silk ingot is Grade B or Grade C, it is determined as "forbidden to pass" and the alarm mechanism is triggered.

[0115] In this way, through the parsing of the first business data by the MES and the accurate judgment of the passing conditions, it can be ensured that only the silk ingots that meet the requirements can continue to be transferred, thereby improving the accuracy and reliability of production. Timely discovering and preventing the transfer of silk ingots that do not meet the passing conditions can reduce abnormal situations in the production process, such as equipment failures and quality problems, thereby reducing production risks. Through automated judgment and indication of passing information, manual intervention and waiting time can be reduced, and the overall operating efficiency of the production line can be improved.

[0116] In the embodiment of the present disclosure, the first PLC obtains the first business data according to the second business data of the target station obtained from the second PLC corresponding to the target station, including: the first PLC converts the second business data into the first business data in the data storage format according to the preset data storage format, where the first business data is stored in the data storage area allocated by the first PLC for the target station, and different types of variables in the first business data correspond to different fixed addresses in the data storage area.

[0117] Here, the data storage format refers to the specific format or specification adopted during data storage or transmission, including data types, data units, data encoding, etc.

[0118] Here, the data storage area refers to a specific area inside the first PLC for storing data.

[0119] Here, the fixed address refers to the unique and unchangeable storage location allocated for different variables in the data storage area. Through the fixed address, rapid access and modification of variables can be achieved.

[0120] In some embodiments, in the automatic ingot passing control system, the first PLC is responsible for generating the first service data of the target station based on the second service data of the target station. These data may include various types of information, such as status codes, numerical parameters, timestamps, etc. The first PLC is internally configured with a preset data storage format to ensure efficient data exchange and parsing between different PLCs or between the PLC and the MES. The first PLC converts the second service data according to this preset format. The conversion process may include data type conversion (such as converting an integer to a floating point number), unifying data units (such as converting from millimeters to inches), decoding data encoding (such as base conversion), etc. The converted data is the first service data, which follows the preset data storage format and is convenient for subsequent processing and transmission. The first PLC assigns a dedicated data storage area for each target station on the production line. The first service data is stored in the data storage area corresponding to the target station. When storing, different variables (such as 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 certain variable, it can be directly accessed through its corresponding address, improving the efficiency of data processing.

[0121] In this way, through the preset data storage format and the format conversion process, the consistency and accuracy of data from different sources during the exchange and processing are ensured. Assigning fixed storage addresses for each variable simplifies the process of data access and processing, improving the overall performance of the system. The allocation and format definition of the data storage area have a certain degree of flexibility and can be extended and adjusted according to the actual needs of the production line.
