Description

Multi-material tracking and tracing method, device, equipment and storage medium TECHNICAL FIELD

[0002] Current supply chain tracking and tracing systems often face the complex management of multiple product materials, especially in the aspects of label scanning and data storage. In traditional supply chain management, tracking multiple product materials often requires the use of different systems or methods, which increases the complexity and cost of management. For example, different types of labels or tracking systems are needed for pre-processing images of different types of product materials, and these systems cannot effectively share or integrate pre-processing images, resulting in information silos and management confusion. In addition, as the supply chain extends and diversifies, product materials will be scanned multiple times at different stages, but current systems cannot effectively update and synchronize data, leading to inconsistent or delayed information. Therefore, existing methods cannot effectively track the transportation and processing of multiple product materials. SUMMARY

[0069] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings, obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0070] The terms "comprising" and "having" and any variations thereof as mentioned in the embodiments of the present application are intended to cover the non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but optionally further includes other steps or units not listed, or optionally further includes other steps or units inherent to the process, method, product or device.

[0071] In order to facilitate the understanding of the embodiments, first, a multi-material tracking and tracing method disclosed by the embodiments of the present application will be described in detail. As shown in FIG. 1, the method comprises the following steps:

[0072] 101, in response to a first scanning operation of a first label scanning device for the first label and the second label respectively, associating the first material and the second material according to the first label and the second label, obtaining at least one association parameter of the first material and the second material;

[0073] In one embodiment of the present application, the first label scanning device is an electronic device specifically designed to read the information on the labels attached to the materials. It is capable of identifying and interpreting electronic labels (such as RFID tags, QR codes, or barcodes, etc.) attached to the materials, thereby obtaining information related to the materials. Such devices are usually equipped with one or more scanning technologies, enabling them to quickly and accurately capture the data on the labels. The first scanning operation describes the actions performed when the first label scanning device first encounters the labels on the first material and the second material. This process involves identifying and reading the data on the labels (the first label and the second label) on each material. The scanning operation can be automatic or manual, depending on the settings of the device and the operating environment. During this process, the scanning device uses its built-in scanning technology (such as optical scanning, radio frequency identification, etc.) to capture information from the labels and convert it into electronic data. The scanning device or subsequent data processing systems will analyze the information read from the first label and the second label according to pre-set logic or algorithms. This information can include product identifiers, batch numbers, production dates, etc., and can be used as a basis for associating the two materials. By analyzing this data, the system can identify the relationship between the two materials, such as whether they belong to the same production batch or need to be processed or transported together. At least one association parameter refers to one or more indicators that the system can determine to represent or quantify the relationship between the first material and the second material after completing the above association process. For example, the association parameter can be the production batch number that the two materials belong to together, or the distribution priority relationship between them.

[0074] 102. generating, by the hardware processing device, first activity data of the first material and second activity data of the second material based on the scanning information of the first scanning operation, the material information of the first material and the material information of the second material, and the at least one association parameter, respectively, and updating the first activity data and the second activity data as storage data to corresponding positions of the storage device through the connection relationship, respectively;

[0075] In one embodiment of the present application, generating activity data for different materials is a critical step in supply chain management that allows businesses to accurately track and manage the status and flow of various materials across production, warehousing, transportation, and other stages. Activity data contains real-time information about materials, such as location, status (e.g., in processing, completed, in transit), timestamps, etc., which helps improve the transparency, efficiency, and responsiveness of the supply chain. The hardware processing device (such as a smart processor that integrates scanning, computing, and communication functions) first reads the tag information on the first material and the second material based on the scanning information obtained from the first scanning operation. This information typically includes product identifiers, batch numbers, production dates, etc. Next, the hardware processing device generates an activity data record for each material by combining the scanned information, specific information about the materials (such as physical characteristics, origin, destination, etc.), and at least one correlation parameter determined through the previous step. This record not only reflects the current status and location of the material, but also includes its relationship with other materials, such as the same production batch or common destination. After generating the activity data, the hardware processing device transmits and updates the first activity data and the second activity data to the corresponding locations of the storage device through a pre-set connection relationship (which can be a network-based interface, wireless communication protocol, etc.). This storage device can be a central database, cloud storage service, or other forms of data storage systems that can securely store, manage, and analyze data from various stages of the supply chain.

[0076] 103. In response to a second scanning operation of the first tag or the second tag by the second tag scanning device, generating, by the hardware processing device, third activity data for the first material or fourth activity data for the second material based on scanning information of the second scanning operation, the first activity data, and the second activity data;

[0077] In one embodiment of the present invention, the primary difference between the first and second label scanning devices lies in their scanning range and purpose. The first label scanning device scans the first and second labels, typically to initially capture or register material information and generate preliminary activity data. The second label scanning device, on the other hand, scans a specific label (either the first or second label). This typically occurs at a later stage in the supply chain, such as logistics transit, warehouse inbound or outbound, or production line input, to update the material's activity data to reflect its latest status. The second label scanning device scans the first or second label at a specific stage in the supply chain. This step occurs in response to the material arriving at a new processing stage or undergoing a status change, and is performed only on one of the labels. The hardware processing device receives scan information from the second scanning operation. This information includes label identification information and may also include a timestamp and location information. Based on this information, the hardware processing device identifies whether the scanned material is the first or second material. The hardware processing device then uses the results of the second scanning operation, combined with the existing first or second activity data, to generate updated activity data (third or fourth activity data). For example, if the second scanning device scans the first label, the hardware processing device will generate third activity data for the first material based on the scanned information and the first activity data. If the second label is scanned, the hardware processing device will generate fourth activity data for the second material. The generated third or fourth activity data is then sent to the storage device via the hardware processing device and a pre-defined connection to update the current status of the material. These updates reflect the material's latest location, status, or other relevant information, providing real-time data support for supply chain management.

[0078] 104. Generate fourth activity data of the second material based on the at least one associated parameter and the third activity data, or generate third activity data of the first material based on the at least one associated parameter and the fourth activity data;

[0079] In one embodiment of the present invention, due to the existence of association parameters, after the product label corresponding to one of the first material and the second material is scanned by a scanning device and activity data is generated, the other material will also synchronously generate activity data based on the association parameters and preset association rules.

[0080] Specifically, the labels associated with each material can be further linked to each other by defining the associations between the materials and the physical relationships between them. When a specific number of product units are shipped in a carton, each product unit has its own label, and the carton has a separate label that defines the relationship between the carton and the product and indicates the specific product unit in the carton. The carton label is the parent of the labels of the product units it contains. The logistics transactions recorded in the tracking and tracing system for each carton will also automatically update the information of the product units in the carton. If a product is removed and its label is scanned at any checkpoint in the supply chain, the data related to the label on the carton will also be automatically updated.

[0081] 105. Update the third activity data and the fourth activity data as storage data to corresponding locations of the storage device respectively according to the connection relationship by the hardware processing device;

[0082] In one embodiment of the present invention, the third and fourth activity data are updated as storage data to specific locations on the corresponding storage devices based on pre-defined connection relationships via a processing device within the system. This process involves the hardware processing device writing the latest activity data to the corresponding storage locations on the storage devices according to pre-established rules and association mechanisms, enabling timely data updates and storage. This process ensures that the data in the storage devices remains up-to-date, facilitating subsequent data query and management operations.

[0083] 106. After the storage device completes updating the stored data, the stored data is displayed on the user device corresponding to the tag scanning device;

[0084] In one embodiment of the present invention, when the storage device completes the update of the stored data, displaying the stored data on the user device corresponding to the tag scanning device includes: when the storage device completes the update of the stored data, determining the user type of the user device corresponding to the current tag scanning device; determining the user rights of the user device according to the user type, and filtering data from the stored data of the storage device according to the user rights; and displaying the filtered stored data on the user device corresponding to the current tag scanning device.

[0085] Specifically, the user types in the supply chain can be diverse, and the user types and permissions are different according to their roles and responsibilities in the supply chain: Suppliers are responsible for providing raw materials or components. They need access to order information, inventory levels, and logistics status related to their supplied products, but do not need access to competitor data or sensitive retailer sales data. Manufacturers process raw materials into final products. They need access to supplier information, production schedules, inventory status, and shipping information to adjust production plans and logistics arrangements. Logistics service providers: responsible for the transportation and distribution of products. They need to obtain information about transportation routes, status updates, and delivery schedules to optimize transportation efficiency and cost. Retailers: Retailers sell products directly to end users. They focus on sales data, inventory status, and market demand information to make restocking and promotion decisions. End users: Although end users usually do not directly participate in supply chain management, they may need access to product origin, authenticity verification, and usage instructions, etc.

[0086] Specifically, according to the permission level of the user, the system filters the corresponding data from the storage device. For example, suppliers may only have access to orders and inventory information directly related to them, while manufacturers can access more extensive supply chain data, including information about all suppliers, production schedules, and inventory status. Data filtering is achieved through advanced database queries and access control lists (ACLs), ensuring that each user type can only access information that is open to them. The filtered data is displayed on the user device corresponding to the current label scanning device. This is usually achieved through a customized user interface (UI) that takes into account the specific needs and permissions of the user. For example, the interface for logistics service providers may focus on displaying transportation routes and status updates, while the interface for retailers may focus more on sales data and inventory status. Data display can use visual tools such as charts, dashboards, and real-time alerts to help users quickly understand information and make decisions.

[0087] Further, the display of the filtered data on the user device corresponding to the current label scanning device includes: determining the product label corresponding to the filtered data as the target product label; obtaining the uniform resource locator corresponding to the target product label, and determining the web address corresponding to the filtered data according to the uniform resource locator; updating the website content of the website corresponding to the web address according to the filtered data; accessing the website corresponding to the web address through the user device corresponding to the current label scanning device, and displaying the website content of the website on the user device corresponding to the current label scanning device.

[0088] Specifically, the system first filters the data stored in the database based on user permissions and requests to find specific information required for a particular user or task. The filtered data is used to determine the labels of the corresponding goods, which serve as target good labels. Each good label contains a unique identifier, such as an RFID tag ID or QR code content, which is directly linked to the stored data, allowing users to quickly identify and track specific goods. Each target good label is associated with a URL that points to a web page containing more information about the goods. The system obtains this URL by parsing the information in the label. The parsed URL is the web address of the page corresponding to the filtered stored data, which the user can access to obtain detailed information. As the status of goods in the supply chain changes (such as inventory levels, logistics status, etc.), the stored data associated with the goods labels will be updated. Correspondingly, the content of the web page located by the label also needs to be updated to reflect the latest information. This is usually done automatically through a background management system, ensuring that the website content is synchronized with the actual situation. After scanning the goods label to obtain the URL, the user device can access the website corresponding to the web address. The content on the website, including text, images, videos, etc., will be displayed on the user device, providing detailed information about the goods, such as specifications, usage instructions, logistics tracking, etc.

[0089] 107. In response to a purchase scanning operation of the third scanning device scanning the first label or the second label, disconnecting the connection relationship between the storage device and the first label or the second label.

[0090] In an embodiment of the present application, the first material is an outer packaging material, and the second material is a product material inside the first material; and the response to the purchase scanning operation of the third scanning device scanning the first label or the second label to disconnect the connection relationship between the storage device and the first label or the second label includes: in response to the purchase scanning operation of the third scanning device scanning the first label or the second label, generating purchase activity data corresponding to the first label or the second label, and updating the purchase activity data as storage data to the corresponding position of the storage device through the connection relationship; determining whether the scanning object of the third scanning device is the first label or the second label; if the scanning object of the third scanning device is the first label, disconnecting the connection relationship between the storage device and the first label and the second label; and if the scanning object of the third scanning device is the second label, canceling the association between the first material and the second material, deleting the at least one association parameter, and disconnecting the connection relationship between the storage device and the second label.

[0091] Specifically, when the third scanning device of the customer or point of sale (POS) system scans the first label or the second label of the product, the system identifies this action as a manifestation of purchase intention. At this time, the scanning action triggers the system to generate purchase activity data corresponding to the scanned label. The generated purchase activity data contains important information such as product identification, purchase time, quantity, etc., and then through a specific connection relationship, these data are updated to the corresponding position of the storage device for further processing and recording. If the scanning object is the first label, the system will disconnect the connection relationship between the storage device and the first label and the second label. This indicates that the product represented by the label on the outer packaging material and the label on the internal product material has been purchased, so its status needs to be updated in the system. If the scanning object is the second label, the system not only disconnects the connection relationship between the storage device and the second label, but also needs to cancel the association between the first material (outer packaging material) and the second material (product material). This usually involves deleting at least one association parameter to reflect the purchase status of the product material itself.

[0092] Specifically, when the first material is scanned, there is no need to cancel the association between the first material (outer packaging material) and the second material (product material), because when the first material is scanned, it indicates that the purchase scanning operation corresponds to the outer packaging material and all product materials in the outer packaging material, while when the second material is scanned, it indicates that the purchase scanning operation corresponds to the product material described in the outer packaging material, and at this time, the association needs to be cancelled, because once the product is purchased, disconnecting the connection relationship can prevent the same product from being repeatedly scanned and processed, thereby avoiding possible errors and confusion, and subsequent updating of the activity data of the first material will not affect the sold second material.

[0093] Further, the product label is an rfid tag and / or a qr code; and the generating, in response to the purchase scanning operation of the third scanning device scanning the first label or the second label, of the purchase activity data corresponding to the first label or the second label comprises: acquiring, through the third scanning device, an rfid tag signal and / or a qr code image of the first label or the second label in response to the purchase scanning operation of the third scanning device scanning the first label or the second label; analyzing the rfid tag signal and / or the qr code image of the first label or the second label to determine the first material or the second material corresponding to the purchase scanning operation; and generating, by the hardware processing device, the purchase activity data corresponding to the first label or the second label based on the scanning information of the purchase scanning operation and the activity data corresponding to the first material or the second material corresponding to the purchase scanning operation.

[0094] Specifically, for a purchase scanning operation, the third scanning device first captures the information of the first label or the second label on the commodity through radio wave or optical scanning technology. This includes receiving wireless frequency signals from RFID labels and / or capturing QR code images. RFID labels and QR codes carry key information about the commodity, such as product identification, batch number, production date, etc. The scanned RFID label signals and QR code images are then sent to a parsing module. This module is responsible for decoding the data contained in these signals and images to determine whether they correspond to the outer packaging material (first material) or the internal product material (second material). This step is crucial for accurately recording the purchase information of the commodity, as it affects the subsequent data processing and inventory management operations. Once it is determined whether the scanning operation corresponds to the first material or the second material, the hardware processing device generates purchase activity data based on the scanning information and the specific activity data of the corresponding material. These activity data reflect the purchase details of the commodity, such as purchase time, quantity, commodity type, etc. The generated purchase activity data is then used to update the corresponding records in the storage device. This not only includes marking the commodity as sold, but also may involve adjusting inventory, generating sales reports, updating customer purchase history, etc.

[0095] Further, when the third scanning device simultaneously scans multiple first labels or multiple second labels and the commodity labels are RFID labels and QR codes, the parsing of the RFID label signals and / or QR code images of the first labels or the second labels to determine the first material or the second material corresponding to the purchase scanning operation includes: inputting the obtained multiple RFID label signals into a preset label positioning model to obtain the label positions of the corresponding first labels or the second labels; positioning multiple QR codes in the QR code images based on the label positions to obtain the correspondence between the RFID label signals and the QR codes; parsing the multiple RFID label signals and the multiple QR code images to obtain signal label information corresponding to each RFID label signal and image label information corresponding to each QR code image; comparing the signal label information corresponding to each RFID label signal and the image label information corresponding to each QR code image according to the correspondence to determine whether the signal label information and the image label information corresponding to the correspondence are consistent; if not, re-determine the correspondence between the RFID label signals and the QR codes; if yes, determine the multiple first materials or the multiple second materials corresponding to the purchase scanning operation according to the signal label information and the image label information corresponding to the correspondence.

[0096] In particular, when scanning multiple RFID tags and QR codes at the same time, the system needs to distinguish and identify the unique information of each tag, especially when these tags are placed closely together. Using a pre-set tag localization model can help the system accurately identify the physical location of each tag, thereby distinguishing them. The tag localization model helps ensure the accuracy of data collection, reducing data confusion and error matching through physical location information, especially in the case of handling a large number of goods. To perform tag localization, first, the system collects the signals of all RFID tags in the surrounding area through the RFID reader. These signals are then input into the pre-set tag localization model, which uses signal strength, direction, and other related parameters to infer the approximate location of each tag. Based on the location information of the RFID tags, the system can then spatially localize the scanned QR code images, i.e., determine the location of each QR code in the physical space. To ensure information consistency, comparing whether the signal tag information and the image tag information are consistent can verify whether they represent the same goods. This is an important step to ensure the consistency of data obtained from two different technologies, avoiding information mismatch caused by technical failure or data processing error. In addition, inconsistent data can lead to incorrect inventory management decisions or customer service problems. By verifying the consistency of the information, the system can correct any errors before continuing processing, ensuring the accuracy and reliability of the data. Once the correspondence between the RFID tag signals and the QR code images is determined and verified to be consistent, the system can use these matched data to determine the specific material (first material or second material) represented by each tag. By integrating information from RFID and QR codes, the system can generate a detailed material list, including quantity, type, and other information. These information can then be used for inventory management, order processing, supply chain optimization, and other business processes.

[0097] Further, when the third scanning device simultaneously scans a plurality of first labels or a plurality of second labels and the product label is a qr code, the determining the first material or the second material corresponding to the purchase scanning operation by analyzing the rfid tag signal and / or the qr code image of the first label or the second label includes: performing image preprocessing on the qr code image of the first label or the second label to obtain a preprocessed image; inputting the preprocessed image into a preset qr code detection model, wherein the qr code detection model includes an input layer, a feature extraction layer, a feature pyramid network, a feature fusion layer, a multi-task detection layer, and an output layer; mapping the preprocessed image to a high-dimensional space through the input layer to obtain initial feature information in the high-dimensional space; performing feature extraction on the initial feature information through the feature extraction layer to obtain convolutional features at different levels; performing upsampling operations on the convolutional features at different levels through the feature pyramid network to obtain upsampling results, and splicing the upsampling results with the convolutional features at different levels to obtain initial fusion features at different levels; performing feature fusion on the initial fusion features at different levels through the feature fusion layer to obtain secondary fusion features; performing multi-task detection on the secondary fusion features through the multi-task detection layer to obtain a plurality of task detection results; determining positioning boxes of a plurality of qr codes in the qr code image through the output layer according to the plurality of task detection results; and analyzing the qr codes in each positioning box to determine the first material or the second material corresponding to the purchase scanning operation.

[0098] Specifically, in the initial stage of processing, the system first processes the RGB image through a specially designed input layer. This layer uses a 7x7 convolutional module, aiming to convert the standard RGB image into a feature representation in a high-dimensional space. This conversion step is crucial for subsequent feature extraction and analysis, as it provides the deep learning model with a rich and manipulable feature set that better captures the details and structural information in the image. Subsequently, the image features are input into the backbone network composed of three residual modules, which constitute the feature extraction layer. The use of residual modules is to address the problem of gradient vanishing that may occur in deep networks, while ensuring effective information transmission in multi-layer networks. The goal of this layer is to extract convolutional features with rich spatial and semantic information, which is crucial for understanding and recognizing QR codes in images. The extracted features are then sent to the feature pyramid network (FPN), a step designed to further enhance the model's ability to recognize targets of different scales. The feature pyramid network can produce feature representations that contain both rich spatial details and strong semantic information by fusing features at different levels. These features processed by the FPN are then sent to the feature fusion layer, which is designed to perform multiple semantic fusions of shallow and deep representations of QR code targets. This fusion strategy ensures that features extracted from different depths can be effectively integrated, providing a more comprehensive and detailed feature basis for accurate QR code detection and recognition. After feature fusion processing, the resulting information enters the multi-task detection layer. This layer performs key point regression, bounding box regression, and bounding box classification tasks, and is the key to accurate QR code detection. The key point regression task locates the corner points of the QR code, the bounding box regression accurately calculates the boundary box of each QR code, and the bounding box classification distinguishes different types of boxes. Finally, the output layer generates the final output image based on the results of the multi-task detection layer, which contains QR code detection boxes, corner point positions, and box category information. In this way, each detected QR code is not only accurately located, but also correctly classified,

[0099] In the embodiment, when the label scanning device scans the product labels on the multiple product materials in different links of the supply chain, corresponding activity data is generated, the activity data is updated as storage data to the corresponding position of the storage device, after the storage device completes the update of the storage data, the storage data is displayed on the corresponding user device of the label scanning device; in response to the purchase scanning operation of the third scanning device scanning the product label, the connection relationship between the storage device and the product label is disconnected. The method generates activity data for querying the state of the article and displays it, can realize efficient supply chain management and material authenticity, and adds a mechanism for transferring ownership authorization during label scanning, when a purchase behavior occurs, the upper associated data involved in the purchase behavior is disconnected, ensuring seamless transfer of ownership information. Finally, the QR code in each positioning frame is parsed, that is, by reading and decoding the data in the QR code, the first material or the second material corresponding to the purchase scanning operation is determined.
