[0002] Although the integration of industrial Internet and 5G technology is driving the transformation of manufacturing towards digitalization and intelligence, the traditional manufacturing model still has significant defects in automation, data management and production process optimization.

[0003] In existing technologies, many factories rely on manual operations and paper records for production management, which is not only inefficient but also prone to inaccurate or lost information. In addition, traditional error prevention measures are mostly post-inspections, which cannot monitor and correct errors in real time during the production process, thereby increasing the defective rate and production costs. With the popularization of the concept of intelligent manufacturing, companies are facing tremendous pressure to upgrade traditional equipment to intelligent systems, but existing solutions are often difficult to achieve seamless integration, limiting the flexibility and responsiveness of the production process.

[0004] Therefore, there is an urgent need for an intelligent error-proofing method that can effectively combine modern information technology and automated control to meet these challenges. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Figure 1 A flowchart of an intelligent error prevention method based on a manufacturing execution system MES and a device control system WinCC provided by an exemplary embodiment of the present invention is shown. The intelligent error prevention method based on a manufacturing execution system MES and a device control system WinCC comprises the following steps: Step S1: Identify and create a recipe file for the product based on the manufacturing execution system MES.

[0030] Specifically, the product identification and formula file creation in the manufacturing execution system MES includes at least the product name, enabling QR code reading, QR code characteristic information on the raw material, enabling MES duplicate code comparison, and enabling MES batch number comparison to create a formula file (see Figure 2 ).

[0031] In the embodiment of the present application, the product is identified and the formula is archived through the manufacturing execution system MES to ensure that the production process of each product is traceable and accurate. The Manufacturing Execution System (MES) is an information system used to optimize the production process of the manufacturing industry. It monitors, controls and manages the entire production process from order placement to product completion in real time. MES ensures the transparency and traceability of production data by integrating functional modules such as production planning, material tracking, quality control, and equipment maintenance, supporting enterprises to achieve efficient, flexible and accurate production operations, while promoting the improvement of production automation and intelligence levels.

[0032] Step S2: before the product is produced, a unique DataMatrix format two-dimensional code is marked on each raw material of the product.

[0033] In the embodiment of the present application, the DataMatrix format two-dimensional code has characteristic information assigned in four directions: up, down, left, and right (see Figure 3 ), DataMatrix format QR code can at least fill in the batch number, serial number, and part number of the product. In detail, DataMatrix format QR code is a two-dimensional barcode that can efficiently encode a large amount of information, with high-density storage and strong error correction capabilities. It is composed of a matrix of black and white squares, supports assignment characteristics in four directions: up, down, left, and right, and can accommodate various types of information including text, numbers, and binary data, such as the batch number, serial number, and part number of the product. DataMatrix QR code is widely used in manufacturing, logistics and other fields. Because of its small size, strong readability, and accurate decoding even if partially damaged, it is very suitable for identifying and tracking items of small size or complex surfaces.

[0034] In the embodiment of the present application, each raw material is uniquely marked with a DataMatrix format two-dimensional code to ensure that each raw material has a unique and traceable identity. The DataMatrix format two-dimensional code used in the embodiment of the present application has characteristic information assigned in four directions, which can efficiently encode and store key data such as the batch number, serial number and part number of the product. This setting not only enhances the full-process tracking capability of raw materials and finished products, but also effectively supports automated production and quality control processes through precise data recording and management, ensures high accuracy and traceability in the production process, reduces the possibility of human error, and improves overall production efficiency and management level.

[0035] Step S3: In response to the raw material identification operation being completed and put online, the production and processing report is made in the manufacturing execution system MES, and the product formula is read through the manufacturing execution system MES and written into the equipment control system WinCC.

[0036] In detail, the above-mentioned reading of product formulas through the manufacturing execution system MES and writing them into the equipment control system WinCC includes: reading product names through the manufacturing execution system MES, enabling QR code reading, QR code characteristic information on raw materials, enabling the manufacturing execution system MES duplicate code comparison, and enabling the manufacturing execution system MES batch number comparison, and writing them into the equipment control system WinCC (see Figure 4). The equipment control system WinCC (Windows Control Center) is an advanced supervisory control and data acquisition (SCADA) software system developed by Siemens and widely used in the field of industrial automation. It is mainly used for the creation and operation of human-machine interfaces (HMIs), allowing users to monitor, control and manage production equipment and process flows through an intuitive graphical interface. WinCC can collect and process data from field equipment in real time, support complex control logic, and provide functions such as alarm management, trend analysis and report generation, thereby helping factories achieve efficient and accurate production operations and optimized management.

[0037] In the embodiment of the present application, when the raw material identification operation is completed and the system goes online, the manufacturing execution system MES reports the production and processing, and automatically reads the product formula information, including the product name, enabling QR code reading, QR code characteristic information on the raw material, enabling duplicate code comparison and batch number comparison, and then writes these detailed information to the equipment control system WinCC. This setting ensures precise control and data consistency of the production process: the manufacturing execution system MES prevents duplicate coding and batch confusion by reading and verifying the unique QR code information of each raw material in real time, ensuring the accuracy of the formula; at the same time, these key parameters are synchronized to the equipment control system WinCC, so that the production equipment can operate according to precise formula instructions, thereby improving the degree of automation of production, reducing human errors, and ensuring product quality and traceability.

[0038] Step S4, in response to the raw materials circulating on the production equipment controlled by the equipment control system WinCC, the QR code characteristic information on the raw materials is read and parsed by the code reader at the code reading station, and the equipment control system WinCC will synchronously receive the QR code characteristic information and pass the QR code characteristic information to the manufacturing execution system MES.

[0039] In an embodiment of the present application, the QR code characteristic information on the raw material includes at least a QR code direction value, a content character length value, and QR code content information. The QR code direction value corresponds to the characteristic information assigned in the four directions of up, down, left, and right of the DataMatrix format QR code. The QR code content information corresponds to the batch number, serial number, and part number of the product that can be filled in the DataMatrix format QR code.

[0040] Specifically, step S4 includes: in response to the raw materials circulating on the production equipment controlled by the equipment control system WinCC, the QR code characteristic information on the raw materials is read and parsed by the code reader at the code reading station, and the equipment control system WinCC synchronously receives the QR code characteristic information and transmits the QR code content information in the QR code characteristic information to the manufacturing execution system MES.

[0041] Step S5: In response to the device control system WinCC receiving the QR code characteristic information, the information is compared with the recipe value of the QR code characteristic information written into the manufacturing execution system MES in step S3 to determine whether to proceed to the next step of processing.

[0042] To elaborate, this step S5 includes: in response to the device control system WinCC receiving the QR code characteristic information, comparing the QR code direction value and content character length value of the raw material reported in step S3 and written into the manufacturing execution system MES to see if they are consistent, the device control system WinCC controls the production equipment to perform the next step of processing on the consistent product raw materials, and removes the inconsistent product raw materials from the next step of processing.

[0043] In the embodiment of the present application, after the device control system WinCC receives the QR code characteristic information, the system will automatically compare the QR code direction value and content character length value of the raw material written by the reporting worker in the manufacturing execution system MES. If these values ​​are consistent, the device control system WinCC will control the production equipment to continue the next step of processing of qualified raw materials; and for inconsistent raw materials, they will be automatically identified and rejected and will no longer enter the subsequent processing flow. This setting ensures that only raw materials that have been verified and meet the expected specifications can participate in production, thereby effectively preventing quality problems caused by incorrect material information, improving the accuracy and reliability of production, and reducing the possibility of waste and rework.

[0044] Step S6: In response to the manufacturing execution system MES receiving the QR code characteristic information, a comparison database is immediately established to perform a comparison operation. For product raw materials that meet the requirements, the manufacturing execution system MES promptly feeds back the equipment control system WinCC to control the production equipment to determine whether to proceed to the next step of processing.

[0045] Specifically, this step S6 includes: in response to the manufacturing execution system MES receiving the QR code content information in the QR code characteristic information, establishing a comparison database for comparison operations to check whether the batch number is consistent with the product report batch number and whether the QR code content information has appeared in the comparison database; if the compared batch numbers are consistent and there is no repeated reading of the QR code content information, the manufacturing execution system MES promptly feeds back to the equipment control system WinCC to control the production equipment to perform the next step of processing, and removes product raw materials that do not meet the requirements and does not perform the next step of processing.

[0046] In an embodiment of the present application, in response to the manufacturing execution system MES receiving the QR code content information in the QR code characteristic information, the manufacturing execution system MES will immediately match the information with a pre-established comparison database, check whether the batch number is consistent with the batch number registered when the product is reported, and confirm whether the QR code content information has appeared in the database. If the batch number is consistent and no repeated reading of the QR code content information is found, the MES will promptly feedback to the equipment control system WinCC, authorizing the production equipment to carry out the next step of processing on the qualified raw materials; conversely, for raw materials that do not meet the requirements, the system will automatically identify and remove them to prevent them from entering the subsequent production process. This setting ensures that only raw materials that have been verified, meet the expected specifications, and have no duplicate records can participate in production, thereby effectively preventing quality problems caused by incorrect or duplicate material information and improving the accuracy and reliability of production.

[0047] Next, the present invention is further described in conjunction with a specific embodiment: Figure 5 A schematic diagram of product A provided by a specific embodiment of the present invention is shown. Product A is a ceramic catalyst. The raw material is a cylindrical ceramic honeycomb carrier. The processing technology is sizing operation in the honeycomb holes above the cylindrical ceramic honeycomb carrier. A batch of 1,000 product A with batch number 24100123 is scheduled for production in October 2024.

[0048] This specific embodiment provides an intelligent error prevention method based on a manufacturing execution system MES and an equipment control system WinCC, which specifically includes the following steps: Step 1: Please refer to Figure 6 , create an error-proof recipe file for the above product A in the manufacturing execution system MES.

[0049] Step 2: Perform DataMatrix two-dimensional code marking on the raw material cylindrical ceramic honeycomb carrier of the production batch 24100123 of product A before production. The content information of the two-dimensional code is "8-digit production batch number + 5-digit carrier serial number". For example, "2410012300001" represents the raw material of batch 24100123, in which one serial number is "00001". In this way, the content of the two-dimensional code from "2410012300001-2410012301000" represents the serial number of 1000 raw materials of batch 24100123 of product A; the character length value of the content of the DataMatrix two-dimensional code of each raw material is 13 bits; the direction 1 of the DataMatrix two-dimensional code of each raw material is toward the top of the carrier (the sizing surface, such as Figure 5 ).

[0050] Step 3: When the raw materials of batch 24100123 of product A are put into production, the production report is made in the manufacturing execution system MES. The manufacturing execution system MES grabs the production batch number and the system-set product A formula table and writes it into the equipment control system WinCC; refer to Figure 7 , turn on QR code reading, turn on QR code length verification, turn on QR code direction verification, turn on duplicate code verification, turn on batch number verification, assign a value to set the QR code length to "13", and assign a value to set the QR code direction to "1".

[0051] Step 4. Each cylindrical ceramic carrier of the 24100123 batch of product A passes through the barcode reader station controlled by the equipment control system WinCC one by one when it is conveyed to the sizing station on the belt line. The barcode reader reads the QR code on the carrier, parses the QR code direction value, content character length value, and QR code content information. The equipment control system WinCC synchronously receives the QR code direction value, content character length value, and QR code content information, and transmits the QR code content information to the manufacturing execution system MES. Step 5. Finally, the equipment control system WinCC will compare the QR code direction value and content character length value of the cylindrical ceramic carrier with the QR code direction "1" and QR code length value "13" written in the report. If the product carrier is consistent, the equipment control system WinCC will control the production equipment to continue to run the carrier to the sizing station for sizing. If the product carrier is inconsistent, the equipment control system WinCC will control the production equipment to grab the carrier and remove it to the abnormal product removal line of the equipment. At the same time, the manufacturing execution system MES will fill in the QR code content information such as carrier No. 00001 "2410012300001" after receiving it. It is loaded into the background database, and the first 8 digits of the QR code are compared to see if it is the product batch number 24100123, and whether the content "2410012300001" has appeared in the database. If the batch numbers are consistent and the content has not appeared in the database, the manufacturing execution system MES will promptly feedback to the equipment control system WinCC to control the production equipment to continue running the carrier to the sizing station for sizing. If the batch numbers are inconsistent or the content has appeared in the database, the manufacturing execution system MES will promptly feedback to the equipment control system WinCC to control the equipment gripper to grab the carrier and remove it to the abnormal product rejection line of the equipment.

[0052] In summary, the present invention integrates the manufacturing execution system MES database function, the equipment control system WinCC automation characteristics, and the special characteristics of the DataMatrix format two-dimensional code, effectively avoiding the problems of processing direction errors, repeated processing, mixed batch production, etc. caused by the raw materials of the products during processing, and realizes the transparency and traceability of the entire production process, effectively preventing the occurrence of potential errors. In addition, with the help of the two-dimensional code as an information carrier, the entire life cycle of each batch of raw materials from storage to finished product delivery can be tracked to ensure the accuracy and consistency of the information, which truly reflects the precise error prevention of production and processing.
