Description

Technical Field

[0001] This invention relates to the field of data acquisition system technology, and in particular to a variable data acquisition system for product traceability in the beverage and beer industry. Background Technology

[0002] Against the backdrop of the beverage and beer industry moving towards smart factories and digital traceability management, the promotion of the "one item, one code" policy continues to intensify. Enterprises have an increasing demand for digital supervision, brand anti-counterfeiting, and marketing interaction. They have generally deployed QR code encoding equipment such as laser machines and UV inkjet printers on production lines and are trying to trace products in conjunction with database systems.

[0003] Currently, the existing technologies in the industry that are relatively similar mainly fall into three categories: 1. Fixed QR code coding and offline data collection system, which uses static QR codes printed on inkjet printers to collect and archive data offline during the warehousing and outbound processes; 2. Traditional packaging line scanning and association system, which uses fixed scanners to sequentially associate bottle codes and box codes, relying on PLC interrupt triggering and industrial control computer processing; 3. Third-party anti-counterfeiting and traceability platforms and cloud services, which generate variable code segments through outsourced platforms to achieve basic traceability functions.

[0004] However, existing technologies have significant drawbacks: variable data is difficult to match in real-time with actual production line rhythms; the static code + post-binding mode easily leads to asynchronous coding and scanning; the bottle-box-pallet hierarchical association logic is incomplete, relying on sequence and time windows for judgment, failing to achieve high-accuracy "many-to-one" or "one-to-many" binding; data interaction between systems is poor, lacking seamless integration with production systems such as MES and WMS, causing information gaps and delays; code data storage lacks lifecycle management, with inadequate management of code status such as printed, scanned, outbound, and abnormal, and no controllable data review capability; it cannot adapt to parallel collaboration of multiple production lines, mostly deployed on a single production line, lacking unified scheduling and centralized management capabilities. These shortcomings make it difficult for existing systems to meet the industry's development needs in terms of flexibility, real-time performance, data accuracy, and system integration.

[0005] Therefore, a variable data acquisition system and acquisition method for product traceability in the beverage and beer industry are proposed to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned technical problems and provide a variable data acquisition system for product traceability in the beverage and beer industry. This invention solves the problems existing in the prior art, such as difficulty in real-time matching of variable data with actual production line rhythm, incomplete hierarchical association logic of bottle-box-tray, poor data interaction between systems, lack of lifecycle management of code data storage, and inability to adapt to parallel collaboration of multiple production lines. At the same time, it meets the needs of digital supervision, brand anti-counterfeiting, and marketing interaction under the promotion of the one-item-one-code policy in the beverage and beer industry.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a variable data acquisition system for product traceability in the beverage and beer industry, including a multi-point acquisition module, a control center, a data association processing module, a user management module, and a platform interface. The multi-point acquisition module includes a bottle code acquisition unit, a box code acquisition unit, a pallet bar code acquisition unit, a conveyor belt, and a control cabinet. The bottle code acquisition unit is installed at the exit of the bottling line, the box code acquisition unit is installed at the exit of the packaging line, and the pallet bar code acquisition unit is installed at the entrance of the palletizing line for collecting QR code / barcode information. The conveyor belt connects the bottling line, the packaging line, the packaging line, and the palletizing line in sequence. The control center is located in the control cabinet.

[0008] The control center is specifically an industrial-grade PLC or industrial computer used for data synchronization, task scheduling, anomaly handling, and data storage at each data acquisition point;

[0009] The data association processing module is used to associate and bind bottle codes, box codes, and pallet codes in multiple levels and many-to-many ways, supporting multiple packaging structures within the same batch.

[0010] The user management module is used to provide users with an operation panel to increase user interactivity;

[0011] The platform interface is used to upload the collected data to the enterprise MES and cloud traceability platform.

[0012] The data acquisition method applied to the variable data acquisition system for product traceability in the beverage and beer industry specifically includes the following steps:

[0013] S1: Work order reception and task initialization. The system receives production tasks from MES / ERP, configures information such as corresponding batch, variety, and packaging specifications, and generates a QR code content template.

[0014] S2: On the bottling line, the inkjet printer prints a QR code with a unique serial number in real time, and the bottle code acquisition unit automatically reads the QR code data through a fixed barcode scanner.

[0015] S3: The barcode scanning devices corresponding to the packaging line and palletizing line collect the box code and pallet code. The system automatically binds the bottle code, box code and pallet code data hierarchically according to the time window and production line signal logic.

[0016] S4: Real-time verification of data format and logic. When missing, duplicate, or incorrect codes occur, an alarm is triggered and the operator is prompted to handle the situation. At the same time, the abnormal data is recorded in the log.

[0017] S5: The collected data after association is stored in the local database and uploaded to the MES system and traceability platform in real time through the industrial communication interface;

[0018] S6: In the inbound and outbound process, handheld terminals such as PDAs are used to scan and verify product codes to prevent cross-selling and missing shipments, and the data is fed back to the system in real time.

[0019] Preferably, the control center includes an MES / ERP communication module, which is used to communicate with the MES / ERP system in real time to dynamically receive work order information and push collection tasks.

[0020] Preferably, the user management module includes a touch-screen human-machine interface (HMI), which is used to display the acquisition status, abnormal warnings, and operation prompts in real time.

[0021] Preferably, the bottle code acquisition unit, box code acquisition unit, and pallet code acquisition unit are all electrically connected to the control center, the conveyor belt is triggered by PLC control, and the MES / ERP communication module communicates with the MES / ERP system via Ethernet.

[0022] Preferably, step S2 specifically includes:

[0023] S21: Use a CO2 laser marking machine, UV marking machine or labeling machine to mark a unique QR code on the empty bottles passing through the bottling line. The QR code content is dynamically issued by the MES system and includes variable information such as production batch, serial number and production time.

[0024] S22: After the QR code is printed, the fixed barcode scanner immediately reads the QR code, and the data is uploaded to the intelligent control center in real time, which also triggers the subsequent packaging process signals.

[0025] Preferably, step S3 specifically includes:

[0026] S31: Packaging line completes boxing, box QR code is collected by high-speed barcode scanner;

[0027] S32: The intelligent control center automatically binds the bottle code with the corresponding box code based on the collected timestamp and the PLC signal of the production line, forming a one-to-many association between bottles and boxes;

[0028] S33: If the box code is missing or duplicated, the system will automatically alarm and prompt manual intervention.

[0029] Preferably, step S5 specifically includes:

[0030] S51: All collected and correlated data is stored in the industrial database built into the industrial control computer;

[0031] S52: Data is uploaded to the enterprise MES system and cloud traceability platform in real time via Ethernet interface to achieve data backup.

[0032] The beneficial effects of this invention are:

[0033] 1. Existing technologies use a static code + post-binding mode, which cannot adapt to the dynamic changes of high-speed production lines. This invention uses a PLC + industrial computer dual control architecture, with real-time linkage between the inkjet printer and the data acquisition unit. The code is scanned immediately after inkjet printing, which is suitable for high-speed production lines of 700 meters / minute. It realizes variable data acquisition and real-time synchronization with the production line cycle time, with data latency approaching zero.

[0034] 2. Existing technologies rely on sequence and time window judgments, which can only achieve simple linear binding and are easily affected by on-site rhythm interference. This invention adopts a multi-level many-to-many association algorithm, which dynamically binds "bottle-box-pallet" data based on timestamps and production line PLC signals, with an association accuracy rate of over 99.9%, perfectly adapting to real packaging scenarios of "many-to-one" and "one-to-many".

[0035] 3. Existing technologies lack the ability to deeply integrate with MES / ERP systems. This invention has a built-in multi-protocol communication module to achieve bidirectional real-time communication with MES / ERP systems, dynamically issue production tasks, and transmit collected data back in real time, thus building a complete data closed loop and improving production scheduling efficiency and information transparency.

[0036] 4. Existing technologies have imperfect code status management and lack controllable data review capabilities. This invention establishes a code data full lifecycle management mechanism, which stores data according to status, supports 30-day local backup, and allows for traceability of abnormal logs, meeting quality analysis and compliance requirements and solving the problem of chaotic data management in traditional systems.

[0037] 5. Existing technologies are mostly deployed on single production lines, resulting in poor adaptability. This invention supports data aggregation across workshops and bases. The headquarters can achieve unified traceability management of multiple factories through a cloud platform. It is also compatible with various barcode scanning devices, packaging specifications, and industrial protocols, making it easy to promote and apply in factories of different sizes. It can also be expanded and integrated with electronic scales and visual inspection equipment to build a complete quality traceability chain. Attached Figure Description

Detailed Implementation

[0051] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0052] like Figures 1-12 As shown, the technical solution adopted by the present invention to solve the above-mentioned technical problems is: a variable data acquisition system for product traceability in the beverage and beer industry, including a multi-point acquisition module 1, a control center 2, a data association processing module 3, a user management module 4, and a platform interface 5. The multi-point acquisition module 1 includes a bottle code acquisition unit 11, a box code acquisition unit 12, a pallet bar code acquisition unit 13, a conveyor belt 14, and a control cabinet 15. The bottle code acquisition unit 11 is installed at the exit of the bottling line, the box code acquisition unit 12 is installed at the exit of the packaging line, and the pallet bar code acquisition unit 13 is installed at the entrance of the palletizing line for collecting QR code / barcode information. The conveyor belt 14 connects the bottling line, the packaging line, the packaging line, and the palletizing line in sequence. The control center 2 is located inside the control cabinet 15.

[0053] Bottle code acquisition unit 11, box code acquisition unit 12 and pallet code acquisition unit 13 are all electrically connected to control center 2, and conveyor belt 14 is controlled by PLC to trigger actions;

[0054] The data acquisition units are precisely positioned according to key nodes of the production line, achieving full-packaging data coverage from bottle to carton to pallet, with a scanning rate of 99.99%, solving the problem of missed scans in traditional decentralized data acquisition. Multiple recognition technologies are compatible with different packaging materials, adapting to the diverse packaging needs of the beverage and beer industry. The conveyor belt and data acquisition units are linked via PLC, ensuring data acquisition and logistics synchronization, avoiding time lag errors common in traditional offline data acquisition. Each data acquisition unit communicates directly with the control center, reducing intermediate transmission links, ensuring data real-time performance, and meeting the cycle time requirements of high-speed production lines.

[0055] Control Center 2 is specifically an industrial-grade PLC or industrial computer used for data synchronization, task scheduling, anomaly handling, and data storage at each acquisition point;

[0056] Control center 2 includes MES / ERP communication module 21, which is used to communicate with the MES / ERP system in real time to dynamically receive work order information and push collection tasks; and the MES / ERP communication module 21 communicates with the MES / ERP system via Ethernet. The control system adopts a dual control structure of industrial-grade PLC + Windows industrial computer.

[0057] The dual-control architecture balances high-speed computing and stable control, ensuring synchronous and delay-free data acquisition on high-speed bottling lines at a maximum speed of 700 meters per minute, thus solving the lag problem of traditional single controllers. The MES / ERP communication module 21 supports multiple industrial communication protocols such as OPC-UA, Modbus TCP, and HTTP API, enabling dynamic distribution of production tasks and real-time feedback of collected data, breaking down information silos and supporting multi-variety mixed-line production and rapid batch switching. Ethernet communication ensures stable data transmission, avoiding data loss or delays associated with traditional communication methods, and meeting the needs of closed-loop management of production data. Local storage supports 30-day backup of collected data, providing assurance for data retrieval and improving the foundation for code data lifecycle management.

[0058] Data association processing module 3 is used for multi-level many-to-many association binding of bottle code, box code, and pallet code, and supports multiple packaging structures within the same batch;

[0059] Built-in multi-level many-to-many association algorithm, it achieves dynamic binding based on the collected timestamp and production line PLC signal, breaking through the limitations of traditional sequential binding and solving the real association needs of "many-to-one" and "one-to-many". The code association accuracy rate reaches over 99.9%. It is compatible with different packaging specifications in the beverage and beer industry, eliminating the need for manual adjustment of binding rules, reducing operational complexity, improving production line adaptability, and solving the defect of traditional systems that only support fixed packaging structure association. It automatically generates box-pallet association records, constructing a complete "bottle-box-pallet" three-level traceability structure, providing core support for full-chain traceability.

[0060] User management module 4 is used to provide users with an operation panel to increase user interaction;

[0061] User management module 4 includes a touch-screen human-machine interface (HMI41), which is used to display the acquisition status, abnormal warnings and operation prompts in real time.

[0062] The HMI is installed on the outside of control cabinet 15. Visual operation lowers the barrier to entry for manual intervention, allowing operators to monitor the production line status in real time. Anomaly alarm response time is <0.2ms, quickly alerting operators to issues such as missing codes, duplicate codes, and incorrect codes, reducing production line downtime caused by manual troubleshooting and solving the problem of untimely anomaly feedback in traditional systems. It supports manual intervention and data verification, further ensuring data accuracy and preventing abnormal data from flowing into subsequent stages. The interface allows for querying related data by batch, shift, and order number, improving the convenience of traceability operations.

[0063] Platform interface 5 is used to upload the collected data to the enterprise MES and cloud traceability platform;

[0064] By integrating data across the entire production, warehousing, and distribution chain, headquarters can centrally manage multiple factories and production lines through a cloud platform, overcoming the shortcomings of traditional single-line deployments that cannot achieve unified control. Real-time data uploads to the MES system enable transparent production management, while uploads to the cloud-based traceability platform support consumer QR code scanning for verification. Combined with an points-based marketing system, it achieves integrated anti-counterfeiting and promotion, expanding terminal application scenarios. Off-site and local data backups provide dual protection, preventing data loss and meeting the long-term retention requirements of traceability data. Open interface standards support integration with electronic scales and visual inspection equipment, linking weight information, appearance quality inspection results, and variable code collection to build a complete quality traceability chain.

[0065] The data acquisition method applied to the variable data acquisition system for product traceability in the beverage and beer industry follows the sequence of task-driven, online acquisition, intelligent association, anomaly handling, data closure, and inbound / outbound verification, specifically including the following steps:

[0066] S1: Control Center 2 receives production tasks from the enterprise's MES or ERP system via MES / ERP communication module 21, automatically configures the corresponding batch, variety, and packaging specifications (e.g., batch 20250622, 500ml bottled beer, 24 bottles / case), and generates a QR code content template. This template includes dynamic variables such as production batch, unique serial number, and production time, which are sent to the coding equipment in real time by the MES system. This enables dynamic data acquisition process control driven by production tasks, meets the needs of multi-variety mixed-line production, and solves the problem of fixed QR code content and lack of dynamic flexibility in traditional systems.

[0067] S21: A unique QR code is printed on empty bottles passing through the bottling line using a CO2 laser marking machine, UV marking machine, or labeling machine. The QR code content is dynamically distributed by the MES system and includes variable information such as production batch, serial number, and production time. The maximum speed of the marking machine is 700 meters per minute, which is compatible with the high-speed production line and supports real-time linkage with the production line.

[0068] S22: After the QR code is printed, the fixed barcode scanner of the bottle code acquisition unit 11 immediately reads the QR code and uploads the data to the control center 2 in real time. At the same time, it triggers the subsequent packaging process signal to ensure that the coding and acquisition are synchronized without delay, and completely solves the problem of asynchronous coding and scanning in the traditional static code + post-binding mode.

[0069] S31: After the packaging line finishes packing, the high-speed barcode scanner of the box code collection unit 12 collects the box QR code with a scanning rate of >99.99%, ensuring the integrity of data collection and avoiding the loss of association due to missed scanning.

[0070] S32: Control center 2 automatically binds bottle codes and box codes of the same batch according to the collected timestamp and production line PLC signal through a many-to-many association algorithm to form a one-to-many "bottle-box" association relationship; then, pallet code collection unit 13 at the palletizing line entrance reads the pallet virtual code or physical code, and the system binds the "bottle-box" association data with the pallet code according to preset rules to complete the construction of the "bottle-box-pallet" three-level relationship, supporting the organization of association data by batch, shift, and order number;

[0071] S33: If there are any abnormalities such as missing or duplicate box codes or pallet codes, the system will automatically alarm through the touch-screen human-machine interface HMI41 to prompt the operator to intervene manually. At the same time, the abnormal data will be recorded in the log to ensure the accuracy of the correlation and the closure of the traceability chain.

[0072] S4: Control Center 2 has a built-in real-time data verification module that performs dual verification on the collected data: format verification ensures that the QR codes conform to the encoding rules, and logic verification ensures that the bottle and carton quantities match and the code segment assignments are correct. If any anomalies such as missing codes, duplicate codes, or incorrect codes are detected, an audible and visual alarm is immediately triggered, and HMI41 simultaneously displays the location, type, and handling prompts of the anomaly, with an alarm response time of <0.2ms. The system automatically records anomaly logs, including the anomaly time, production line, data content, and handling results, providing a basis for subsequent quality traceability and process optimization. This step effectively reduces errors, missing codes, and duplicate codes, solving the problems of traditional systems that rely on manual anomaly checks and have poor stability.

[0073] S51: All collected and associated data is stored in the industrial database built into the industrial control computer. It is classified and managed according to the code status: sprayed, scanned, associated, out of stock, and abnormal, realizing full lifecycle tracking of code data. Local storage supports 30-day backup of collected data to meet data review and compliance requirements.

[0074] S52: Data is uploaded to the enterprise MES system and cloud traceability platform in real time via Ethernet interface, realizing data backup and multi-terminal sharing; the upload process uses industrial communication protocol to ensure stability, ensuring that the data in the warehouse is consistent with the system records in real time, solving the problems of data upload delay and information lag in traditional systems, and completing the production data closed loop.

[0075] S6: In the warehousing and outbound processes, staff use PDA handheld terminals to scan and verify product codes. The system combines the unique QR code with shipping data to compare regional authorization and logistics routes, automatically identifying and alerting distributors' cross-regional sales activities to prevent cross-selling, misdelivery, and omissions. The verification results are fed back to control center 2 in real time to update the product circulation status. This step not only ensures the accuracy of warehousing and logistics but also provides technical support for channel anti-counterfeiting management. Consumers can scan the code on their terminals to access the system's database for traceability verification. The system can also be integrated with a points-based marketing system to achieve integrated anti-counterfeiting and promotional functions.

[0076] Control center 2 includes MES / ERP communication module 21, which is used to communicate with the MES / ERP system in real time to dynamically receive work order information and push collection tasks.

[0077] User management module 4 includes a touch-screen human-machine interface (HMI41), which is used to display the acquisition status, abnormal warnings, and operation prompts in real time.

[0078] Bottle code acquisition unit 11, box code acquisition unit 12 and pallet code acquisition unit 13 are all electrically connected to control center 2. Conveyor belt 14 is triggered by PLC control. MES / ERP communication module 21 communicates with MES / ERP system via Ethernet.
