Description

Technical Field

[0001] The present invention relates to the fields of information technology and identification resolution technology, and specifically to a cross-enterprise automobile parts tracing method based on an industrial Internet identification resolution system. Background Art

[0002] The Industrial Internet is a key infrastructure, a new application model and a new industrial ecology for the deep integration of the new generation of information and communication technology and the industrial economy. The Industrial Internet includes networks, security and platforms. As an important part of the Industrial Internet network system, the Industrial Internet identification resolution system is the nerve center that supports the interconnection and interoperability of the Industrial Internet. By giving each physical object or virtual resource a unique "identity card", it realizes cross-regional, cross-industry and cross-enterprise information sharing and interoperability. In June 2018, under the guidance of the Ministry of Industry and Information Technology and the strong support of local governments at all levels, the China Academy of Information and Communications Technology officially launched the construction of the National Top-level Node for Industrial Internet Identification Resolution. At present, a four-level architecture of "root node, national top-level node, secondary node, and enterprise node" has been established, and the layout goal of "having a system, traffic, application, and covering the whole country" has been initially achieved. The results of identification application are gradually emerging and gradually penetrating into various industries and links of the industrial system.

[0003] However, the construction of the identification resolution system is still in the development and promotion stage, and most of the enterprise management information systems were built earlier than the identification resolution system. On the one hand, the enterprise resource management system (ERP), supply chain management system (SCM), customer management system (CRM), manufacturing execution system (MES) and other systems have stored product-related information, and there are inconsistent information storage standards for products in different systems. On the other hand, from the perspective of the industry and the enterprise, there are multiple sets of coding standards coexisting, and different identifications cannot be interconnected. Including: enterprises use private identification, which cannot be read across enterprises; upstream enterprises use the identification specified by downstream enterprises, and enterprises need to maintain multiple identification systems; upstream and downstream enterprise information systems are connected, and the cost of system interconnection and integration is high. Generally, product information is represented by identification, and each enterprise has its own set of coding rules. The coding rules of different enterprises are incompatible, and it is difficult to achieve unified data query. For a product, there are multiple coding rules in the industry and enterprise. Due to different protocol standards and interfaces within related enterprises in the industry, between enterprises, and between industries, data is difficult to communicate, share and integrate between systems and industries, thus forming a "data island". Data standards are not unified, data elements are not circulated smoothly, and data rights confirmation, transaction and utilization are difficult. There are many codes, private codes are everywhere, and the private systems built and used by various enterprises are incompatible with each other. The addressing, parsing, clarifying, modeling and interaction of massive heterogeneous data consumes a lot of human computing power. There are still certain technical and administrative difficulties in breaking through data silos.

[0004] In addition, most manufacturing companies have initially realized the transformation of manufacturing automation, management digitization, and networking. Various types of companies have established their own traceability systems for their own needs, and data islands are everywhere: leading companies have established a parts traceability system based on VIN codes to meet their own corporate management needs; e-commerce platforms have implemented a one-code anti-counterfeiting traceability system for each item due to transaction needs; supply chain companies have also established many traceability systems for their own needs. These plans are all proposed by development companies, lack unified standards, lack effective government supervision and credible certification, and some illegal businesses can use technical means to produce and sell counterfeit goods, forge traceability information, and other means to achieve false product traceability query results. These behaviors seriously affect the public's trust in label traceability. Summary of the invention

[0005] The present invention aims to at least solve the technical problems existing in the prior art, and particularly innovatively proposes a product traceability method and platform based on the industrial Internet identification resolution system, which has the universality and authority to be promoted to other industries.

[0006] In order to achieve the above-mentioned object of the present invention, the present invention provides a cross-enterprise automobile parts traceability method and system based on the industrial Internet identification resolution system, comprising the following steps:

[0007] S1, Enterprise Node Prefix Application: Industry-leading enterprises deploy the secondary node platform for identity resolution, providing industry-oriented identity coding registration and resolution services; the secondary node platform for identity resolution is interconnected with the national top node platform and the enterprise node platform; the secondary node platform registers the enterprise node prefix for the enterprise; the enterprise submits the identity resolution enterprise node prefix application on the secondary node platform, the secondary node platform approves and allocates the prefix, and deploys the enterprise node platform for the enterprise;

[0008] S2, traceability user registration: the enterprise deploys the enterprise node platform, applies to join the traceability management platform, and opens a traceability management platform account;

[0009] S3, product identification registration: The enterprise initiates identification registration for its own design, production, circulation, maintenance, use, recycling, scrapping and other traceability information to its own enterprise node, and obtains a unique identification code belonging to the enterprise's products. The traceability information and product identification code data are distributed and stored in the enterprise's local server; the identification code information contains partial information owned and shared by each enterprise about the product in a certain link of its life cycle.

[0010] S4, traceability code application and association: the enterprise applies for the traceability code on the traceability management platform and associates the product identification code with the traceability code; the identification code and traceability code are expressed in the form of QR code, RFID tag, etc.

[0011] S5, traceability information query: the enterprise or individual user scans the code through the traceability application terminal to identify the traceability code, obtains the traceability code number, obtains the identification code associated with the traceability code on the traceability management platform, and then performs an identification query on the identification resolution secondary platform according to the identification code to obtain the identification query symbol; then, the enterprise node platform is queried according to the identification query symbol to obtain all traceability information related to the traceability code.

[0012] Through the above method, it is possible to record information of products through various links and enterprises during the circulation process, and store the recorded information in real time to the distributed storage server, forming a cross-enterprise traceability information flow at the application layer.

[0013] Furthermore, if the original label of the enterprise is associated with a URL, the original label URL is associated with the traceability code URL, and the traceability code URL is obtained by jumping when scanning the traceability code.

[0014] At this time, in step S5, when querying the traceability information, the original label of the enterprise is scanned and identified, rather than the traceability code. The original label of the enterprise is in the form of a QR code, an RFID label, etc.

[0015] Through the above method, enterprises do not need to change the original coding rules, do not need to rebuild the information system, do not need to replace the existing coding labels and reading equipment, but only need to connect the existing data to the product traceability platform to achieve compatible third-party label identification.

[0016] Furthermore, it also includes: after obtaining all traceability information related to the traceability code, comprehensively screening the traceability information to obtain the product's production information, quality inspection information, circulation information and enterprise information.

[0017] Furthermore, if the product is an assembly or an associated part, the traceability code of the product will be associated with the traceability codes of other products that belong to the same assembly or associated part, forming a data mapping and data lineage relationship of the assembly and associated part information, thereby obtaining more complete, comprehensive and structured assembly and associated part traceability information.

[0018] At this time, when querying the traceability information in step S5, not only all the traceability information related to the traceability code of the current product is obtained, but also all the traceability information of the traceability codes of other products belonging to the same assembly or associated parts as the current product is obtained.

[0019] Furthermore, the traceability management platform includes: an enterprise management module, a rights management module, a traceability code management module, an identification management module and a template management module;

[0020] Enterprise management module: including approval of enterprise entry, setting enterprise type, assigning prefixes, automatically generating keys and secret keys, and synchronizing the prefix list generated by the secondary node;

[0021] Permission management module: including user department management, configuration of associated enterprises; user role management, configuration of functional permissions for different roles; user list and menu configuration management;

[0022] Traceability code management module: traceability code application, addition, viewing, downloading and association of product identification, and query of traceability code activation and association;

[0023] After the traceability code application is issued, it is automatically generated according to the coding method determined by the system. After the traceability code is associated with the product identification, the product traceability information can be queried through the mobile terminal or interface. The user associates the existing product identification with the traceability code to form a traceability information chain, and can perform classified searches by keywords such as traceability code, product name, product type, etc.; the anti-counterfeiting and channel diversion possibility can be judged by the number of product scans and location information.

[0024] Identification management module: associate enterprise templates, add new product identification, register identification information; support importing the original enterprise code for identification code generation and prefix splicing; support batch maintenance of identification attribute content of products in the same batch, and apply the initial information configured in the corresponding template. Support querying identification information from the secondary node according to identification code, product type, product brand, etc.

[0025] Template management module: Administrators configure basic traceability information templates for different business types for users to reference; users can apply basic templates, delete fields according to their own needs, and configure their own templates;

[0026] Furthermore, it also includes a data report module:

[0027] The number of identification applications is obtained from the identification management module, and the data on traceability code application, activation, association, and number of scans are obtained from the traceability code management module, and a traceability code status report is automatically generated; based on the information correlation analysis of the number of scans and the scanning location of a single product, risk information on anti-counterfeiting and channel diversion is prompted or warned.

[0028] Furthermore, the traceability application terminal is a mobile device, such as a mobile phone and / or a PDA.

[0029] The present invention also proposes a cross-enterprise product traceability system based on industrial Internet identity resolution, including: a traceability management platform, a traceability application system, an enterprise node platform, and an identity resolution secondary node platform;

[0030] Among them, the traceability management platform is used within the enterprise, and the enterprise uses it for identification registration, data management, and account management; the traceability application system is the entrance and exit for querying the traceability information chain. Users scan the code through the mobile terminal to identify the product traceability code, jump to the traceability application system, and initiate a query application to the identification resolution system, which returns and displays the queried traceability information chain; the enterprise node platform and the identification resolution secondary node platform are used to obtain the code after scanning the product code and initiate information query to the identification resolution system;

[0031] The traceability management platform, traceability application system, enterprise node platform, and identity resolution secondary node platform all have corresponding servers, namely, the traceability platform server, traceability application system server, identity resolution enterprise node distributed storage server, and identity resolution secondary node platform server.

[0032] The traceability management platform includes an enterprise management module, a permission management module, a template management module, an identification management module, and a traceability code management module. The traceability management platform does not store traceability information, but only stores the relationship between the identification code of the product registered to its locally deployed enterprise node at different stages and different enterprises and the traceability code authorized to the enterprise by the traceability platform. This approach will reduce the risk of enterprise data security, and the data sovereignty belongs to each enterprise entity, which will motivate enterprises to share traceability information.

[0033] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0034] 1. Use distributed data storage on the local server of the enterprise, and associate the identification code with the traceability code in the traceability management platform, that is, find the corresponding identification code on the traceability management platform according to the traceability code, and then query the traceability information through the secondary node and enterprise node of the industrial Internet identification resolution system in turn according to the identification code of the traceability management platform. In this way, data islands can be connected and data sharing between upstream and downstream of the industrial chain can be realized. And as a third-party traceability platform, the traceability management platform is more fair and objective. The traceability management platform does not store traceability information, but only stores the association between the identification code of the product registered to its locally deployed enterprise node at different stages and different enterprises and the traceability code authorized to the enterprise by the traceability platform. This method will reduce the risk of enterprise data security, data sovereignty belongs to each enterprise entity, and mobilize the enthusiasm of enterprises to share traceability information.

[0035] 2. By adopting the traceability method of the present invention, the enterprise does not need to change the original coding rules, does not need to rebuild the information system, does not need to replace the existing coding labels and reading equipment, and only needs to connect the existing data to the product traceability system.

[0036] 3. The cross-enterprise product traceability system based on industrial Internet identity resolution proposed in the present invention is an open cloud platform that all enterprises can apply for. Since the enterprise node hosting uses the hardware resources and operation and maintenance costs of the secondary node, the enterprise node can be applied for free; in addition, the hosting service can be applied for. There is no need to invest heavily in software and hardware, and the cost of use and operation and maintenance is low. Moreover, based on the national industrial Internet identity resolution system, this service is free and secure, the data on the platform is publicly shared, and data sovereignty and data security are guaranteed. In addition, it is also possible to consider backend management through a browser, and scanning the code to trace through the WeChat applet, without the need to install additional applications and software.

[0037] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] The present invention is designed and developed based on the national industrial Internet identification resolution system. Through the industrial Internet identification resolution system (identification resolution system), the unified code (identification code) is used to replace the existing code or to perform coding mapping conversion, which can achieve the compatibility and interoperability of industry identification and enterprise identification, and this is an efficient, low-cost and secure solution.

[0045] In addition, this method does not change the original coding rules, codes, labels and scanning equipment of each enterprise during the product life cycle. The enterprise does not need to make any modifications. It only needs to register the original code and related information of the enterprise to the identification resolution system, and use the code generated by the identification resolution system as the secret code for data mapping; obtain the product traceability code through the traceability management platform, and use the traceability code as the plain code for product traceability information query; the relevant enterprises within the product life cycle bind the plain code with the secret code through the platform, and realize the purpose of identifying the plain code on the product by scanning the code, calling the identification resolution system to query, retrieve, locate, and resolve all secret code related information associated with the plain code, and obtaining the traceability information through the traceability application (the traceability application is carried on the traceability application terminal).

[0046] In addition, the traceability management platform supports the association of traceability codes between assembly parts and related parts. By establishing an association between the traceability codes of different products, data mapping and data lineage relationships between assembly parts and related parts are formed, and more complete, comprehensive and structured traceability information of assembly parts and related parts is obtained. For example, the strong association between the identification codes and traceability information of electric vehicles, batteries and charging equipment.

[0047] If the enterprise product has used the original label URL of the enterprise and does not agree to use the traceability code provided by this method as the object of scanning and identification, this method and system support associating the original label URL of the enterprise with the traceability code URL. The application layer is compatible with the identification of third-party labels, and can also query, retrieve, locate, and parse to obtain all secret code related information associated with the enterprise label, so as to achieve the purpose of information traceability.

[0048] The cross-enterprise product traceability system based on industrial Internet identity resolution proposed in the present invention includes: a traceability management platform, a traceability application system (software for querying traceability code information), an identity resolution secondary node platform, and an enterprise node platform. Among them, the traceability management platform is used within the enterprise, and the enterprise uses it for identity registration, data management, account management, etc. The traceability application system is the entrance and exit for querying the traceability information chain. The user scans the code through the mobile terminal to identify the product traceability code, jumps to the traceability application system, and initiates a query application to the identity resolution system, and returns and displays the queried traceability information chain. The enterprise node platform and the identity resolution secondary node platform are used to obtain the code after the product scans the code and initiate an information query to the identity resolution system.

[0049] The traceability management platform, traceability application system, identity resolution secondary node platform, and enterprise node platform all have corresponding servers, namely, the traceability platform server, traceability application system server, identity resolution secondary node platform server, and identity resolution enterprise node distributed storage server.

[0050] The traceability management platform includes an enterprise management module, a permission management module, a template management module, an identification management module, and a traceability code management module. The traceability management platform does not store traceability information, but only stores the relationship between the identification code of the product registered to its locally deployed enterprise node at different stages and different enterprises and the traceability code authorized to the enterprise by the traceability platform. This approach will reduce the risk of enterprise data security, and the data sovereignty belongs to each enterprise entity, which will motivate enterprises to share traceability information.

[0051] The traceability management platform includes the following functional modules:

[0052] Connect the identification management system with the enterprise information system, obtain product information in the enterprise information system, and generate metadata templates. At the same time, connect with the enterprise node to submit the product information of the enterprise information system to the identification resolution system for registration, generate identification data according to the metadata template, and manage the identification data.

[0053] The identification management system generates traceability codes according to a certain identification coding method. Users scan the physical carrier of the traceability code, such as a QR code, RFID tag, etc., and associate it with the existing identification code of the product to form a coding mapping relationship, thereby obtaining all identification information associated with the product's life cycle, and realizing full-chain traceability of product information from production, quality inspection, circulation, trading, maintenance, quality assurance and other links, achieving full life cycle information traceability of "traceable source, traceable process, known destination, and safe use".

[0054] The enterprise management module is connected to the secondary platform of identity resolution to manage enterprise-related information, including approving enterprise entry, setting enterprise type, allocating prefixes, automatically generating keys and secret keys, and synchronizing the prefix list generated by the secondary node.

[0055] The permission management module includes user department management, configuration of associated enterprises; user role management, configuration of functional permissions for different roles; user list and menu configuration management.

[0056] Traceability code management module: traceability code application, addition, viewing, downloading and association with product identification, you can query the activation and association of traceability code. After the traceability code application is issued, it is automatically generated according to the coding method determined by the system. After the traceability code is associated with the product identification, you can query and obtain the product traceability information through the mobile terminal or interface. The user associates the existing product identification with the traceability code to form a traceability information chain, and can perform classified retrieval through keywords such as traceability code, product name, product type, etc.; judge the possibility of anti-counterfeiting and channel diversion through the number of product scans and location information.

[0057] Identification management module: associate enterprise templates, add product identification, register identification information; support importing the original enterprise code for identification code generation and prefix splicing; support batch maintenance of identification attribute content of products in the same batch, and apply the initial information configured by the corresponding template. Support querying identification information from the secondary node according to identification code, product type, product brand, etc.

[0058] Template management module: Administrators configure basic traceability information templates for different business types for users to reference; users can apply basic templates, delete fields based on their own needs, and configure their own templates.

[0059] Data report module: obtains the number of identification applications from the identification resolution system, obtains data such as traceability code application, activation, association, and number of scans from the traceability code module, and automatically generates a traceability code status report. Based on the correlation analysis of information such as the number of scans and the scan location of a single product, it can provide prompts and warnings for risk information such as anti-counterfeiting and cross-selling.

[0060] The traceability application system includes a display interface for scanning and identifying the traceability code. The platform uses the traceability code to associate the product production information, quality inspection information, circulation information, etc. registered by all relevant companies in the product life cycle. In the form of data mapping and association, the information is classified and displayed in the order of registration time. The product company information, production information, quality inspection and certification information, circulation information, transaction information, maintenance information, etc. are displayed. The application system background records the number of times the user scans the code and the location information, and displays it according to the scanning and identification time. The location information is obtained by synchronizing with Amap data. By comparing the number of times the same product is scanned and the location information, the company is prompted with an anti-counterfeiting warning.

[0061] The traceability user registration specifically includes:

[0062] Step 1.1 The enterprise applies for "Enterprise Registration" on the traceability management platform, submits relevant information and materials, and registers as a user of the traceability management platform; at the same time, applies for the identity resolution enterprise node prefix to become an enterprise node.

[0063] Step 1.2 After receiving the registration application, the platform administrator shall review the information provided by the enterprise in accordance with the requirements of the relevant administrative license for identification resolution, and assign the enterprise node prefix after approval; review the enterprise type based on the information provided by the enterprise, and clearly define "manufacturing enterprise", "quality inspection enterprise" and "distribution enterprise".

[0064] Step 1.3 The platform manager deploys the enterprise node platform for the enterprise.

[0065] The product identification registration specifically includes:

[0066] Step 2.1 The enterprise creates an "enterprise template" through the template management module, that is, configures the basic template of traceability information of different business types to display public traceability information. The created enterprise template is used to provide attribute columns when registering the enterprise logo, such as name, specifications, etc. The system provides basic templates created in accordance with industry standards. Enterprises can quote basic templates, delete fields based on their own needs, and configure them into their own enterprise templates. ① Click Add → ② Enter the basic information of the enterprise template → ③ Click Confirm → ④ End.

[0067] Step 2.2 The enterprise configures the initial information of the template in the enterprise template to quickly assign attribute content to the enterprise logo, such as the product name, specifications and other specific content. ① Click to edit the initial information → ② Click to add → ③ Enter the attribute content → ④ Click to confirm → ⑤ End

[0068] Step 2.3 The enterprise associates the enterprise template through the identification management module and applies for a new enterprise identification, that is, to apply for a unique identification for the public information of a single product at its own enterprise node. This module supports importing the original enterprise code for identification generation and splicing prefixes. ① Click Product Identification Management → ② Click Add → ③ Click Confirm → ④ End

[0069] Step 2.4 Fill in the identification attribute content and register the identification information. This step can reference the enterprise template attributes and the initial template information, and supports batch maintenance of the identification attribute content of the same batch of products through table import. Supports querying identification information from the secondary node according to identification code, product type, product brand, etc. ① Click Product Identification Management → ② Click Batch Supplement Attributes → ③ Click Submit → ④ End. Identification registration can be maintained by manual entry or batch import of tables. It also supports automatic registration through the standard interface document provided by the traceability platform and integration with the enterprise management system.

[0070] Step 2.5 After the traceability platform obtains the enterprise identity registration information, it initiates automatic registration to the identity resolution enterprise stage through the interface. After the identity registration is successful, the registration information is written back to the traceability platform through the interface.

[0071] Step 2.6 After the logo is successfully registered, you can query the status and information of the logo in the "Product Logo List" and edit the basic information of the attributes.

[0072] The traceability code application and association specifically include:

[0073] Step 3.1 The enterprise submits a traceability code application to the traceability platform administrator in the "Traceability Management" module.

[0074] Step 3.2 The traceability platform administrator applies for the traceability code through the "Business Management" module, click "Add" and enter the number of traceability codes before submitting. After the traceability code status changes to "Generation Completed", click Download in the operation bar to obtain the traceability code txt file, which will be distributed to corporate users. The company will engrave, print or post the traceability code on the product. ① Apply for a traceability code → ② Add → ③ Enter the number of applications → ④ Click Submit → ⑤ Click Download → ⑤ End

[0075] Step 3.3 The enterprise can view the traceability code list obtained in the "Traceability Management" module. In the "Product Identification Management" module, click "Online Association" to make a one-to-one association between the enterprise identification code and the traceability code. ① Click Product Identification Management → ② Click Online Association → ③ Click Submit → ④ End

[0076] Step 3.4 The platform supports enterprises to import product identification, associated identification and traceability codes in batches. Download the data template through the "Enterprise Management" module, maintain the template information offline, upload the data file, and then batch traceability code association can be performed. ① Click to import enterprise code → ② Click to download the import form → ③ Enter the enterprise code and traceability code → ④ Select the file and upload → ⑤ Select the import enterprise → ⑥ Click Save → ⑦ End

[0077] Step 3.5 The platform supports automatic traceability code association through the standard interface document provided by the traceability platform and integration with the enterprise management information system. ① Call the "Authentication" interface to obtain token information → ② Call the "Apply for Identification" interface to apply for product identification → ③ Call the "Download Code Package" interface to obtain the applied identification → ④ Call the "Identification Association" interface to associate the traceability code and the identification → ⑤ Call the "Traceability Code Associated Enterprise Code" interface to associate the integrated traceability code with the enterprise internal code → ⑥ Call the "Batch Supplement Template Attributes" interface to complete the content information of the identification → ⑦ End

[0078] The traceability information query specifically includes:

[0079] Step 4.1 The user scans the product QR code through a mobile terminal or mobile phone, identifies the traceability code URL associated with the QR code, and matches the QR code in the database to see if it is a traceability code or enterprise code. If so, jump to the traceability application system. The process is to read the corresponding enterprise code and traceability code information through the Excel content imported by the user, verify whether there are duplicate values ​​or empty values ​​in the enterprise code in the Excel content, and respond to the corresponding import exception information. Query the database by obtaining the traceability code in Excel. If the traceability code does not exist, respond to the exception information that the corresponding traceability code does not exist. Determine whether there is already an association relationship between the enterprise code. If it already exists, replace the old associated traceability code with the new traceability code. If there is no association relationship, add a new association relationship data between the enterprise code and the traceability code. ① Scan the product QR code → ② Match whether the URL is in the coding database → ③ Directly query the traceability code or match the traceability code through data association → ④ End

[0080] Step 4.2 Using the JAVA language, the traceability application system queries the traceability management platform for all product identification codes associated with the traceability code. First, check whether the identified coding information exists in the platform database. If the traceability code information does not exist, query the enterprise coding information again; if the code exists, obtain the corresponding product identification. If the code does not exist, the traceability application system prompts that the code does not exist. ① Query the traceability code → ② Match the product identification code associated with the traceability code → ③ End

[0081] Step 4.3 After obtaining all product identification codes associated with the traceability code, the traceability application system initiates a query request for all identification codes to the secondary node of the identification resolution through the JAVA language. Query the coding identification in the secondary node through the traceability code request. If the coding does not exist, the traceability application system prompts information such as the coding does not exist. If it does exist, query the identification coding information through the coding representation request. The traceability application system initiates a query request for all identification codes to the secondary node of the identification resolution. ① Query the traceability code → ② Match the product identification code associated with the traceability code → ③ Call the "Query Identification" interface of the secondary node to obtain the identification attribute name and content → ④ End

[0082] Step 4.4 After querying all the identification information associated with the traceability code, return to the traceability application system and display the identification information on the "Production Information", "Quality Inspection Information", "Distribution Information", and "Enterprise Information" pages in the order of the attributes and registration time of the enterprise production, quality inspection, and distribution enterprises through the JAVA language. ① Query the identification attribute content → ② Query the identification type of the traceability application system (production / quality inspection / … / distribution identification) → ③ Match the enterprise to which the identification belongs → ④ Query the enterprise introduction → ⑤ Assemble the attributes and type information of the identification → ⑥ Display it on the traceability code result page → ⑦ End

[0083] Step 4.5 During the traceability information query process, the mobile terminal scanning history, the geographical location and number of traceability code scanning records, and other information will be recorded in the traceability management platform to form a data analysis report. The platform will count the number of identification registrations, the number of traceability code associations, the number of traceability code scans, and other data on a daily basis, and record them in statistical reports. By time or enterprise and other conditions, the registration base scan count and recent change trends can be queried, summarized, and displayed in a chart. The user-side traceability application system can query the scanning history of this user. ① Click on the scanning history → ② Click on the traceability code for historical query → ③ Query the identification attribute content of the traceability code → ④ End.

[0084] The traceability platform server is used in conjunction with a traceability application terminal, which is used to scan product codes. The traceability application terminal is a mobile device such as a mobile phone or a PDA.

[0085] The traceability application terminal obtains the unique traceability code of the product by scanning and identifying the QR code label, and queries the traceability management platform for all product identifiers (identification codes) associated with the traceability code through the JAVA programming language, and then initiates a query request to the secondary node and enterprise node server. Finally, the queried product traceability information is edited through the JAVA programming language and displayed on the application terminal. The displayed content includes production information, quality inspection information, traceability information and enterprise information. The template for information display content is customized according to industry standards and the actual situation of the enterprise.

[0086] In addition, enterprises can also deploy traceability application systems (local deployment) according to their own needs, which can be implemented through traceability application system servers. The traceability application system server initiates traceability information query instructions to the secondary nodes and enterprise nodes of the identity resolution system through software design, and maintains and manages enterprise information, product information and traceability information through the enterprise management module, authority management module, template management module, identity management module and traceability code management module of the traceability management platform.

[0087] The distributed storage server is interconnected with the traceability platform server via the Internet or wireless nodes.

[0088] In addition, there is an application layer: the application layer is interconnected with the traceability application terminal through the Internet or wireless nodes. The application layer is the intranet of several enterprise nodes, or the wireless node of the end user. A distributed storage server is set up in each enterprise user of the application layer.

[0089] Enterprises linked at the application layer can cross industries and regions, linking enterprises in the entire life cycle of product design, production, circulation, quality inspection, maintenance, after-sales, recycling, and scrapping. Each enterprise sets up a distributed storage server to deploy an identity resolution enterprise node, and uses the interface provided by the traceability management platform and the enterprise node platform interface document (the traceability platform and the enterprise node platform both provide common interface documents to facilitate automatic data interaction between systems). The traceability management platform, the enterprise node platform and the enterprise's existing management information system are connected in an integrated manner. The product information of the enterprise management information system is automatically registered with the identity resolution enterprise node (enterprise node) according to the information traceability requirements, and a unique identification code and its identification information about the information of the enterprise's product are generated (the identification code and its identification information are stored on the enterprise node platform, and the association between the identification code and the traceability code is stored on the traceability management platform), forming the traceability information of the product at different stages of different enterprises, which is distributed and stored in each enterprise node platform server (i.e., distributed storage server). The enterprise operator applies for a unique traceability code through the traceability management platform, and associates the identification code of the enterprise's product with the traceability code operation on the traceability management platform. It can also be automatically associated after integration with the enterprise's existing management information system through the interface document provided by the traceability management platform. After the application layer initiates the information query instruction of scanning the code to identify the traceability code, the traceability management platform finds all the identifiers associated with the traceability code through the code association relationship, initiates a query application to the identifier resolution system, obtains all the associated identifier information, and displays it to the user in a centralized manner after classification and matching in the traceability application system.

[0090] The specific steps of the cross-enterprise automotive parts traceability method based on the industrial Internet identification resolution system are as follows:

[0091] In the present invention, each enterprise applies for and deploys an industrial Internet identity resolution enterprise node, registers product information to the identity resolution system through the enterprise node, and generates an identification information belonging to the enterprise;

[0092] The enterprise applies for a unique traceability code from the traceability platform, which is an authoritative third party, and associates the enterprise's product identification code with the traceability code through the traceability platform; the traceability application system initiates a query demand, searches for all identification codes associated with the traceability code through the traceability platform, and sends a query request to the Industrial Internet Identifier Resolution System. After classifying and processing the returned query information, the product traceability information provided by each enterprise node is displayed in the traceability application system, including production information, quality inspection information, circulation information and enterprise information.

[0093] Enterprise node information registration and traceability code association support manual entry, batch import and system integration. The enterprise's industrial barcode scanning terminal can be integrated with the traceability management platform through an interface to identify the product traceability code, and write and read product information to the traceability management platform and the enterprise information system respectively (when the mobile terminal is a barcode scanning gun REP system). The company's automated coding equipment can be connected to the traceability management platform through the network to automatically spray the traceability code logo on the product. Users can scan the traceability code with their mobile phones and obtain product traceability information without downloading additional mobile applications. PC users can access it through a browser without installing a software package. The traceability management platform is open to all companies based on this set of technologies. Companies only need to apply for an account to use the platform.

[0094] In order to achieve the above purpose at the lowest social cost, this method supports the cross-enterprise product information traceability of the entire life cycle of product production, circulation, use, maintenance, scrapping and recycling without changing the original coding rules, coding, labeling and scanning equipment of the enterprise. This method registers the original coding and information of the enterprise into the identification resolution system. The identification code generated by each enterprise for the product will be used as a secret code, which is associated with the unique product traceability code (plain code) generated by the traceability platform to form a product traceability information chain. Users can scan the code to identify the traceability code, and then query, retrieve, locate and resolve all the secret code (identification code) related information associated with the plain traceability code to achieve the purpose of information traceability. This coding association method can be extended to the information association between product assemblies and related parts. By establishing an association relationship between the traceability codes of different products, a data mapping and data lineage relationship of assembly and related parts information is formed, and more complete, comprehensive and structured assembly and related parts traceability information is obtained. Furthermore, in order to more conveniently and effectively support enterprises to achieve the purpose of traceability information query without changing existing labels, this method supports associating the enterprise's original label URL with the traceability code URL to be compatible with the identification of third-party labels and achieve the purpose of information traceability.

[0095] To achieve the above-mentioned purpose, the present invention provides a product traceability method and system based on the industrial Internet identification resolution system, which is used to solve the problems of data sharing and data interoperability between upstream and downstream of the industrial chain. The main processes include traceability user registration, product identification registration, traceability code application and association, and traceability information query. The systems involved include an identification resolution secondary node platform, an enterprise node platform, a traceability management platform and a traceability application system.

[0096] The secondary node platform for identity resolution is an industry or regional identity resolution public service node platform, which is connected to the national top-level node upward and to the enterprise nodes within the industry or region downward, allocates enterprise node prefixes, and provides identity resolution services.

[0097] The enterprise node platform obtains the top-level node prefix, secondary node prefix, enterprise node prefix and product random code automatically assigned by the enterprise node platform, and generates a unique product identification code belonging to the enterprise that cannot be known in advance. After the identification information is registered to the enterprise node, the data is distributed and stored in the enterprise local server.

[0098] This embodiment supports an interface mode, and after integration with the enterprise's existing information system and PDA terminals, data access is performed, and information registration and query services are performed in batches and automatically.

[0099] The method of the present invention proposes a cross-enterprise product tracing method based on identity resolution, such as Figure 1 As shown: the task is initiated by scanning the traceability code on the mobile terminal, the traceability application system is mobilized, and a query command for all enterprise product identification codes associated with the traceability code is initiated to the traceability management platform. The traceability management platform then initiates an instruction to parse all product identification code information to the secondary node. Through the layer-by-layer parsing of the identification code, the secondary node points to the corresponding enterprise node, and obtains the product identification information registered to the enterprise node by the enterprise through its own management information system. Then, it is returned to the traceability application system from the enterprise node and the secondary node layer by layer. After the traceability application system classifies and processes the data, it displays all cross-enterprise product traceability information associated with the traceability code on the page.

[0100] This traceability method is divided into three parts: Figure 2 , Figure 3 As shown, there are code registration, code association and code query. Code registration refers to the product traceability enterprise user registering its product information to the enterprise node platform to generate a product identification code; code association refers to the enterprise user associating the product traceability code assigned by the platform with the product identification code generated by the enterprise node through the traceability management platform, and associating the traceability codes between related products as needed to form a data mapping relationship. Code query refers to the user scanning the code to identify the traceability code label, or the enterprise label associated with the traceability code through the traceability application system, initiating an identification query application to the identification resolution system, obtaining all identification information associated with the traceability code, and forming a traceability information display.

[0101] The operation process of applying for and registering traceability information is: add a new enterprise template - configure the initial information of the template - add a new enterprise logo - fill in the logo attribute content - associate the logo with the traceability code. Figure 2 The platform divides enterprises into three categories: production, quality inspection and distribution enterprises. After obtaining data by category, they are displayed in different traceability information pages. Figure 4 As shown. Production mark (corresponding to Figure 4 Product information): The identification information used by the manufacturer of the product and other enterprises is displayed in the [Production Information] column after the traceability code is associated; Quality inspection identification (corresponding to Figure 4Quality control information): The quality inspection enterprise shall have the quality inspection qualification and obtain the certification invitation from the traceability platform, and the identification information shall be displayed in the [Quality Inspection Information] column after associating the traceability code; the circulation identification (corresponding to Figure 4 Traceability information): The platform / dealer / distributor and other enterprise application identifications in different links of commodity circulation in the market are associated with the traceability code and displayed in the [Circulation Information] column. There is also enterprise information.

[0102] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and its drawings under the concept of the present invention, or directly / intuitively applied in other related technical fields are included in the patent protection of the present invention.
