[0052] Example 1

[0053] Reference Figure 1The first embodiment of the present application provides a product information traceability method based on industrial Internet of Things, which is applied to an industrial Internet of Things system. The industrial Internet of Things system includes a user platform, a service platform, a management platform, a sensor network platform and an object platform that interact in sequence. The method includes:

[0054] S10, obtaining a target product, and decomposing the target product into a plurality of secondary products.

[0055] Optionally, the target product can be a gas meter, which is now explained by taking a gas meter as an example. The gas meter mainly includes the following key parts: the shell, which is used for the external protection structure of the gas meter, usually made of metal, to protect the internal measuring mechanism and electronic components from the influence of the external environment; the metering chamber, which is the core component of the gas meter, contains a precise mechanical structure inside, and is used to measure the volume of gas passing through the gas meter; the impeller or piston, which is a component that rotates with the flow of gas, and its rotation speed is proportional to the gas flow rate, and is a key measuring element in the metering chamber; the gear transmission system, which is used to convert the rotation of the impeller or piston into countable pulses or mechanical indications to record and display the gas consumption; the solenoid valve and the valve, the solenoid valve is used to control the flow of the gas source, and is the key component for the gas meter to realize automatic control, and the valve is responsible for controlling the switch of the gas source. If the gas source is abnormal or there is a safety hazard, the valve will automatically close to protect the life and property of the user; it also includes auxiliary components such as sensors, pressure loss adjusters, support brackets and joints. When producing gas meters, some standard parts may be purchased directly from cooperative manufacturers, such as solenoid valves and valves, and finished products can be purchased directly; for some parts, semi-finished products may be purchased from superior manufacturers first, and then the semi-finished products may be reprocessed in the factory to better adapt to the design of the gas meter of the factory, etc. For example, the metering room may purchase some semi-finished products, and then adjust the mechanical mechanism in the metering room through processing equipment or manually. In the prior art, only the parts of the factory are usually recorded, and the information of the semi-finished products produced by the superior manufacturer is not recorded. This leads to that when the product information is traced, it can usually only be traced back to the factory, and the entire production process of the product cannot be traced, which is not conducive to improving the traceability accuracy of the target product. Therefore, when the target product is a gas meter, the secondary product can be part or all of the components of the housing, metering chamber, impeller, piston, gear transmission system, sensor, pressure loss adjuster, support bracket and joint.

[0056] S20. Obtain a factory code of at least one upper-level manufacturer for each secondary product.

[0057] Specifically, for each type of secondary product, the factory code of at least one superior manufacturer is obtained. When there is only one superior manufacturer for this type of secondary product, one factory code is directly obtained. If there are two or more superior manufacturers for this type of secondary product, the information of all superior manufacturers generating this type of secondary products can be integrated into one factory code, or multiple factory codes can be set accordingly.

[0058] S30. When each of the secondary products is reprocessed, a reprocessing code is assigned to the secondary product.

[0059] Specifically, the generation of reprocessing codes usually follows a set of preset rules, which may include but is not limited to the following information: product type, initial processing date, production batch number, expected reprocessing process, and unique identifier of the production line, etc. Such a coding design ensures that each secondary product can be accurately identified and tracked when it enters the reprocessing stage.

[0060] During the reprocessing process, every time a secondary product goes through a process, the relevant operation information (such as processing time, operator, raw materials or auxiliary materials used, number of processing equipment, etc.) will be associated with the reprocessing code of the product and recorded in the company's production management system. In this way, once a quality problem occurs or the processing history of a product needs to be traced, the company can quickly locate the specific product batch and processing link and take timely measures to rectify or optimize.

[0061] S40. After all the secondary products are assembled into the target product, a finished product code and a product sales code are generated, and the sales code is respectively bound to the factory code, the reprocessing code and the finished product code, so that the factory code, the reprocessing code and the finished product code can be obtained through the sales code.

[0062] Specifically, the finished product code is generated based on the characteristics of the assembled target product, the production date, the batch number, and the secondary products used (including their reprocessing codes). The uniqueness of this code ensures that each finished product can be accurately identified, which facilitates subsequent inventory management, quality traceability, and customer service. The code described in this application can be a barcode, a QR code, an RFID electronic tag, etc.

[0063] The product sales code is generated when the finished product is ready for sale. It not only contains the basic information of the finished product, such as product model, specifications, production date, etc., but more importantly, it will be used as a unique identifier to connect the product's factory, reprocessing, finished product and final sales.

[0064] In order to ensure the integrity and traceability of information, enterprises will bind the sales code with the factory code (recording detailed information when the product leaves the factory, such as the factory date, inspection report, etc.), the reprocessing code (reflecting the historical record of secondary product reprocessing) and the finished product code. This binding process is usually achieved through the enterprise's information management system to ensure the accuracy and real-time nature of the data.

[0065] Through such a coding binding mechanism, enterprises can easily realize the full-chain traceability of products. Whether consumers check the authenticity of products, dealers track the flow of products, or enterprises conduct quality analysis and inventory management, they can quickly obtain full-chain information such as product delivery, reprocessing and finished products through sales codes. This not only improves the management efficiency of enterprises, but also greatly enhances consumers' trust and satisfaction with products.

[0066] In summary, binding the sales code with the factory code, reprocessing code and finished product code is an important means to achieve full-chain traceability of products. It not only helps companies strengthen product quality management and optimize inventory control, but also provides consumers with more transparent and reliable product information. It is an important measure to enhance the market competitiveness and brand image of enterprises.

[0067] Specifically, product information refers to: information about the target product itself, such as product attributes and quality. Information about the various secondary products after the target product is decomposed, including the factory code and reprocessing code of the secondary products. Information about the upper-level manufacturer of the secondary products, such as the manufacturer name and product factory information. Information about the target product assembly process, such as assembly steps, timestamps, verification results, etc. Information about the sales and logistics distribution of the target product, such as sales code, logistics code, distribution code, etc.

[0068] Example 2

[0069] Based on Example 1, this embodiment provides a product information traceability method based on the industrial Internet of Things, which is applied to the industrial Internet of Things system. The industrial Internet of Things system includes a user platform, a service platform, a management platform, a sensor network platform and an object platform that interact in sequence. The method includes:

[0070] S10, obtaining a target product, and decomposing the target product into a plurality of secondary products.

[0071] S20. Obtain a factory code of at least one upper-level manufacturer for each secondary product.

[0072] The step of obtaining the factory code of at least one upper-level manufacturer of each secondary product comprises:

[0073] S21, obtaining the factory information of the secondary product sent by at least one upper-level manufacturer;

[0074] Optionally, the factory information includes attribute information, quality information, identification information of the secondary product and manufacturer information of the upstream manufacturer.

[0075] Specifically, attribute information may include basic information such as the model, specification, material, color, etc. of the secondary product. This information helps the enterprise confirm whether the secondary product meets the design requirements. Quality information covers the quality inspection report, test data, yield rate, etc. of the secondary product. This information is an important basis for the enterprise to evaluate the quality of the secondary product. Identification information such as the serial number, batch number, factory code, etc. of the secondary product is the key to achieving product traceability. Through identification information, the enterprise can trace the production source and processing history of the secondary product. The manufacturer information of the superior manufacturer includes the name, address, contact information, etc. of the superior manufacturer. This information helps the enterprise communicate or collaborate with the superior manufacturer when necessary.

[0076] S22. According to the factory information, a preset number of secondary products belonging to the same batch are packaged and a factory code is generated.

[0077] Optionally, you need to filter out the secondary products of the same batch from the factory information obtained from the upper-level manufacturer. The products in this batch should have the same attribute information, such as model, specification, material, etc., to ensure their consistency and interchangeability. At the same time, carefully check the quality information of each product, including inspection reports, test data, etc., to ensure that they all meet the established quality standards.

[0078] During the packaging process, the products will be packaged according to the preset quantity, and the same number of secondary products will be placed in each packaging unit. In order to ensure the accuracy and traceability of the packaging, clear identification information can be attached to each packaging unit, including product name, model, specification, quantity, batch number and production date, etc. This identification information will help manufacturers and customers quickly and accurately identify the source and batch of the product during subsequent use and tracking.

[0079] Next, a unique factory code will be generated for each packaged secondary product. This code will contain all the key information of the product, such as manufacturer information, product attributes, batch number, factory date, etc. Through this code, the entire process of product tracking and management can be achieved, from production to sales, to final use and scrapping, all of which can be accurately recorded and queried through this code.

[0080] In addition, in order to further optimize and expand this process, you can also consider introducing an information management system. Through this system, you can realize the automatic entry and query of factory information, improve work efficiency and accuracy. At the same time, you can also use this system to monitor and manage the flow of products in real time to ensure product safety and traceability.

[0081] Optionally, the step of obtaining the factory code of at least one upper-level manufacturer of each secondary product further includes: obtaining a first yield rate of each secondary product produced by the upper-level manufacturer, and a second yield rate when the secondary product is reprocessed;

[0082] According to the first yield rate and the second yield rate, the yield rate of each secondary product is predicted, and the yield rates of all secondary products are ranked.

[0083] When the target product fails, the secondary products are eliminated according to their yield rates from low to high.

[0084] Specifically, according to the importance of the sound field secondary products of the superior manufacturer and the importance of processing, the weight coefficients of the first yield rate and the second yield rate are configured. For example, the mass coefficient of the first yield rate is set to 0.3, and the weight coefficient of the second yield rate is set to 0.7. Since the first yield rate is 98.6 and the second yield rate is 97.5, the final yield rate is A=98.6×0.3+97.5×0.7=97.83, and then the final yield rate of each secondary product is calculated, and the obtained structures are sorted from large to small. The higher the yield rate, the less likely the secondary product is to fail than the secondary product with a low yield rate. When the target product fails, it can be used as a reference to more quickly discover the cause of the failure of the target product.

[0085] Furthermore: The first yield rate refers to the initial yield rate of each secondary product produced by the upper-level manufacturer, which reflects the stability of the manufacturer's production process and its quality control ability. The second yield rate refers to the yield rate during the reprocessing of the secondary product, which reflects the impact of the reprocessing process on product quality.

[0086] Based on these two yield rate data, the company can predict the final yield rate of each sub-product and rank the yield rates of all sub-products. The importance of this step is that it helps the company understand which sub-products are more likely to have quality problems, so that they can be given more attention and inspection in the subsequent assembly and production process.

[0087] When a target product (such as a smart gas meter) fails, companies can troubleshoot by following the yield of secondary products from low to high. This means that companies will first check secondary products with lower yields because they are more likely to be the cause of the failure. This approach helps improve the efficiency and accuracy of troubleshooting and reduce unnecessary disassembly and inspection work.

[0088] Let's take a specific example to illustrate this process:

[0089] Assume that a smart gas meter consists of three secondary products: metering module, display module and communication module. While obtaining the factory code, the company also obtains the first and second yield rates of these three modules from the upper-level manufacturer. After calculation and prediction, the company finds that the final yield rate of the metering module is the lowest, followed by the display module, and the communication module has the highest yield rate.

[0090] When a smart gas meter fails, the company will first check the metering module because it is the secondary product with the lowest yield rate and is most likely to be the cause of the failure. If there is no problem with the metering module, the company will then check the display module and finally the communication module. With this method, the company can locate the cause of the failure more quickly, improve maintenance efficiency and user satisfaction.

[0091] S30. When each of the secondary products is reprocessed, a reprocessing code is assigned to the secondary product.

[0092] When each of the secondary products is reprocessed, the step of assigning the secondary product a reprocessing code comprises:

[0093] S31, obtaining image information and parameter information of the secondary product before reprocessing;

[0094] S32. Obtain the processing procedure information and the person responsible for the reprocessing of the secondary products;

[0095] S33, generating a reprocessing code, and binding the image information, parameter information, processing procedure information and the person responsible for reprocessing to the reprocessing code.

[0096] Specifically, in the process of obtaining image information, by taking photos or videos of the secondary products before reprocessing, record their intuitive features such as appearance, size, shape, etc. This helps to quickly identify the product in the subsequent process and compare the changes before and after reprocessing. Parameter information mainly includes collecting basic parameters of secondary products, such as material, weight, hardness, etc. This information is crucial to understanding the performance and characteristics of the product, and is also an important basis for reference during the reprocessing process. Record each process involved in the reprocessing of secondary products in detail, including processing methods, equipment, time, etc. This helps to trace the processing history of the product and find out possible problem links. Clarify the person responsible for each process so that when problems arise, the relevant personnel can be quickly found to investigate and rectify the responsibilities. Bind the image information, parameter information, processing process information and the person responsible for reprocessing with the reprocessing code. In this way, as long as the reprocessing code is entered, all information related to the secondary product can be quickly obtained.

[0097] For ease of understanding, the flow meter is used as an example to illustrate as follows:

[0098] S31: Obtain image information of the flow meter before reprocessing, including appearance photos, interface details, etc.

[0099] Collect parameter information of flowmeter, such as flow range, accuracy level, working pressure, etc.

[0100] S32: Record the processing information of the flow meter reprocessing, including cleaning, calibration, assembly and other processes, as well as the equipment and materials required for each process. Identify the person responsible for each process, such as Zhang San is responsible for the cleaning process, Li Si is responsible for the calibration process, and Wang Wu is responsible for the assembly process.

[0101] S33: Generate a unique reprocessing code for this batch of flow meters, such as "GT-20230401-001".

[0102] The above-mentioned image information, parameter information, processing procedure information and the person responsible for reprocessing are bound to the code and entered into the enterprise's information management system.

[0103] S40. After all the secondary products are assembled into the target product, a finished product code and a product sales code are generated, and the sales code is respectively bound to the factory code, the reprocessing code and the finished product code, so that the factory code, the reprocessing code and the finished product code can be obtained through the sales code.

[0104] After assembling all the secondary products into the target product, the step of generating the finished product code and the product sales code comprises:

[0105] S41, according to the preset assembly process of the target product, decomposing the preset assembly process into multiple assembly steps;

[0106] S42, after each assembly step is completed, a timestamp is assigned;

[0107] S43: Compare the time interval between the start time of assembling the target product and the last timestamp with a preset range, and output a verification result, wherein the verification result includes verification pass and verification fail.

[0108] Specifically, the preset assembly process of the target product (such as a gas meter) is decomposed into multiple specific assembly steps, such as installing sensors, connecting lines, assembling housings, and calibrating and testing. It is possible to consider introducing automated or intelligent equipment to assist assembly and improve production efficiency and accuracy. After each assembly step is completed, an accurate timestamp is immediately assigned to the step to record the completion time of the step. The timestamp information is associated with the person in charge of the assembly step, the materials used, the equipment status, and other information, so that problems can be quickly traced and located in the future. The time interval between the start time of assembling the target product (gas meter) and the last timestamp (i.e., the assembly completion time) is calculated and compared with the preset assembly time range. If the time interval exceeds the preset range, it means that there may be an abnormality or delay in the assembly process, which needs to be immediately checked and processed. At the same time, the time interval data can be compared with historical data to analyze the changing trend of assembly efficiency and provide a basis for subsequent production optimization. According to the comparison results, the verification results are output, including verification passed (the time interval is within the preset range) and verification failed (the time interval exceeds the preset range).

[0109] Optionally, the step of comparing the time interval between the start time of assembling the target product and the last timestamp with a preset range and outputting a verification result as verification failure includes:

[0110] According to the timestamp, obtain the completion time of each assembly step;

[0111] comparing the completion time of each assembly step with a preset time period for each assembly step;

[0112] According to the output result, at least one faulty assembly step is obtained.

[0113] Specifically, in the case of failure of verification, the completion time of each step is accurately obtained according to the timestamp of each assembly step previously assigned. A timestamp database or spreadsheet can be established to organize the completion time, person in charge, materials used and other information of each step for subsequent analysis and query. A reasonable preset time period is set for each assembly step of the gas meter, which should be based on normal production efficiency and process requirements. The completion time of each assembly step is compared with the corresponding preset time period. If the completion time of a step exceeds the preset time period, it is marked as a potential fault step. According to the comparison results, at least one (possibly multiple) faulty assembly steps are found, which are the reasons for the entire assembly time interval exceeding the preset range. The faulty steps are analyzed in depth to find out the specific reasons for the delay or abnormality, such as equipment failure, material shortage, improper operation, etc. At the same time, corresponding improvement measures are formulated, such as repairing equipment, replenishing materials, training operators, etc., to prevent similar problems from happening again.

[0114] For ease of understanding, we will still use a gas meter as an example. Suppose that when assembling a gas meter, it is found that the overall assembly time exceeds the preset range. The following are the specific steps:

[0115] Get completion time:

[0116] According to the previously recorded timestamps, the completion time of each assembly step of the gas meter (such as installing the sensor, connecting the line, assembling the housing, calibration testing, etc.) is obtained.

[0117] Compare preset time periods:

[0118] Set a reasonable preset time period for each assembly step, for example, installing a sensor may take 3-8 minutes, connecting the wiring may take 4-10 minutes, etc.

[0119] Compare the completion time of each step with the corresponding preset time period and find out the steps that exceed the preset time period.

[0120] Get the fault steps:

[0121] Assuming that it is found that the completion time of the step "connecting the wires" is far beyond the preset time period, it can be determined that this step is a faulty assembly step.

[0122] Conduct in-depth analysis of the "connecting lines" step to identify specific causes of delays, such as difficulty in connection due to complex lines and unskilled operators.

[0123] According to the analysis results, formulate corresponding improvement measures, such as simplifying line design, strengthening operator training, etc., to improve assembly efficiency and accuracy.

[0124] Optionally, after assembling all the secondary products into the target product, the step of generating a finished product code and a product sales code further includes:

[0125] When the target product is distributed through logistics, a logistics code and a distribution code are generated, and the sales code is bound to the logistics code and the distribution code respectively.

[0126] Specifically, a unique sales code is generated for the target product. The sales code should be associated with the finished product code so that the specific product can be tracked during the sales process. The sales code can be used for product sales management, inventory management, customer relationship management, etc. Through the sales code, you can quickly query the product's sales records, inventory status, customer feedback and other information, providing data support for the company's sales strategy. When the target product is ready to be shipped, a unique logistics code is generated for it according to the requirements of the logistics distribution system. The logistics code should contain the basic information of the product, shipping address, receiving address, etc. During the distribution process, a delivery code is generated for the target product. The delivery code should be associated with the logistics code to track the delivery status of the product. The sales code is bound to the logistics code and the delivery code respectively. In this way, the logistics information and delivery status of the product can be queried through the sales code; at the same time, the specific sales records and product information can also be traced through the logistics code and the delivery code.

[0127] For ease of understanding, we will still use the gas meter as an example:

[0128] Assuming that you are dealing with the sales and distribution of a batch of gas meters, the following are the specific steps:

[0129] Generate finished product code: After the gas meter is assembled, a unique finished product code is generated for each gas meter according to the preset coding rules (such as "GT-YYYYMMDD-XXX", where "GT" represents the gas meter, "YYYYMMDD" represents the production date, and "XXX" represents the production batch and serial number).

[0130] Generate product sales code: When the gas meter is ready for sale, generate a sales code for it (such as "S-GT-YYYYMMDD-XXX-SN", where "S" stands for sales, "GT-YYYYMMDD-XXX" is the finished product code, and "SN" is the sales serial number). The sales code is associated with the finished product code to ensure that the specific product can be tracked.

[0131] Code generation and binding in the logistics distribution process:

[0132] When the gas meter is ready for shipment, a logistics code is generated for it according to the requirements of the logistics distribution system (such as "L-GT-YYYYMMDD-XXX-LN", where "L" stands for logistics, "GT-YYYYMMDD-XXX" is the finished product code, and "LN" is the logistics serial number).

[0133] During the distribution process, a distribution code is generated for each gas meter (such as "D-GT-YYYYMMDD-XXX-DN", where "D" stands for distribution, "GT-YYYYMMDD-XXX" is the finished product code, and "DN" is the distribution serial number).

[0134] Bind the sales code with the logistics code and the delivery code. In this way, during the sales, logistics and delivery process, you can query the detailed information of the product through the corresponding code to ensure the full traceability of the product.
