Detailed Description
The application provides a block chain-based quality and safety tracing method and system for imported frozen food, which are used for meeting the supervision requirement of quality and safety tracing of the imported frozen food.
It should be noted that the block chain-based imported frozen food quality and safety tracing method provided by the present application may be applied to a terminal, and may also be applied to a server, for example, the terminal may be a smartphone, a portable computer terminal such as a computer and a tablet computer, or a fixed terminal such as a desktop computer. For convenience of explanation, the server is taken as an execution subject for illustration in the present application.
Referring to fig. 1, fig. 1 is a block chain-based method for tracing the quality safety of an imported frozen food provided by the present application, the method comprising:
101. receiving frozen product information uploaded by a frozen product enterprise, wherein the frozen product information comprises frozen product batch information and frozen product quality safety information;
the frozen product enterprise refers to the first station enterprise of an imported frozen product supply chain and is the first station in the whole process of entering from customs to store sales. When frozen goods are put in storage, frozen goods information is required to be filled in a system by a frozen goods enterprise, and the frozen goods information comprises frozen goods batch information and frozen goods quality safety information. Specifically, the frozen product batch information includes information such as the batch number and specification of the frozen product; and the quality safety information of the frozen products comprises the information of customs declaration, quarantine inspection certification, nucleic acid detection certification and the like of the frozen products. The frozen product information further includes information on persons who contact the frozen product in the frozen product enterprise area, information on a refrigerator in which the frozen product is temporarily stored, and information on an enterprise address.
Frozen goods information can be input into the server by the frozen goods enterprise through the small program, and the server receives the frozen goods information uploaded by the frozen goods enterprise and executes subsequent operation according to the received frozen goods information.
102. Generating an electronic two-dimensional code according to the frozen product batch information;
the server generates a unique electronic two-dimensional code for each batch of frozen products according to the batch information of the frozen products, the unique electronic two-dimensional code is hereinafter referred to as a 'freezing tracing code', and the 'freezing tracing code' is used as a unique circulation tracing two-dimensional code of the batch of frozen products, and plays an important role in realizing closed-loop tracing management from the first station of a supply chain to the minimum package of products in a consumption link. The 'traceable freezing code' is related to all the frozen product information of the batch of frozen products, namely the batch number, specification, customs declaration, quarantine inspection certification, nucleic acid detection certification and other information of the batch of frozen products can be determined through the 'traceable freezing code'.
Specifically, the 'freeze tracing code' can be pasted on a package of the frozen product, so that subsequent dealer enterprises and consumers can trace the information of the frozen product by using the 'freeze tracing code'.
103. Uploading frozen product information to a block chain;
the invention utilizes a block chain technology, takes imported frozen products as chain loading objects, comprehensively masters the complete flow direction of the imported frozen products from customs entry to store sales, and realizes the full chain tracing of people association through information recording of contact personnel related to the full chain. The core of a blockchain network is a distributed ledger in which all transaction information occurring in the network is recorded. Blockchain ledgers are generally defined as decentralized because each participant holds a copy of the blockchain ledger throughout the network, with all participants maintaining the ledger together through collaboration. In addition to decentralization and collaboration, another significant feature of the blockchain is that information can only be recorded in an 'attached' manner in the blockchain, and meanwhile, the use of encryption technology ensures that transactions cannot be tampered once added into the ledger. This non-tamper property of the block chain makes the confirmation of the information source exceptionally easy, and the participant can be sure that the information is hardly tampered once it is written in the block chain.
Therefore, the server uploads the received frozen product information to the block chain, and the frozen product information recorded by the frozen product enterprise is used as a first node for full-chain closed-loop management of the frozen products.
104. Receiving dealer information uploaded by a dealer enterprise, wherein the dealer information is uploaded by the dealer enterprise through scanning the electronic two-dimensional code;
in the whole process of importing the frozen products from customs to stores for sale, the frozen products are distributed by multi-stage distributors. When the frozen product is circulated to the first-level dealer by the frozen product first-station enterprise, the first-level dealer can inquire the information of the frozen product by scanning the 'code of tracing to freeze', and when the dealer enterprise scans the 'code of tracing to freeze', the dealer enterprise also uploads the information of the dealer to the server. The dealer information includes information on personnel who contact the frozen product in the dealer enterprise area, information on an enterprise address, and the like.
105. Uploading the dealer information to a block chain, and connecting the frozen product information and the dealer information in series to form a chain;
and after receiving the dealer information uploaded by the first-level dealer, the server uploads the dealer information to the block chain, associates the dealer information with the frozen product information, and connects the dealer information and the frozen product information in series to form a chain as a second node for full-chain closed-loop management of the frozen product.
It should be noted that there may be distribution of multiple dealers before the frozen product enters the terminal store for sale, so the server will repeat steps 104 to 105 to receive and upload the dealer information of other dealers to the blockchain, set the third, fourth, and nth nodes, and so on until the frozen product enters the terminal store.
106. Receiving consumer information uploaded by a consumer, wherein the consumer information is uploaded by the consumer through scanning an electronic two-dimensional code;
after the frozen product enters a terminal store for sale, a consumer can scan the 'freezing code tracing' pasted on the frozen product to inquire the related information of the frozen product when purchasing the frozen product. Specifically, the server may specifically set the frozen product information and the distribution information that the consumer can preview, that is, may select to hide or display a specific item of information of the frozen product. For example, the related information of the frozen product includes information of the current batch of products, product warehousing time, inspection and quarantine certification, customs declaration form, supervision warehouse-out certification, product batch number, origin, primary supplier and the like, the server can set the inspection and quarantine certification and the customs declaration form in the information as previewable, the consumer can only inquire the two information by scanning the 'freezing code tracing', and other information is hidden for the consumer. The consumer can clearly know whether the imported frozen product is legal or not, whether the imported frozen product is subjected to government centralized supervision and treatment or not, whether the imported frozen product is subjected to nucleic acid detection or not and other key information through code scanning. The consumer can master the whole circulation process of the frozen product through scanning the code, so that the consumer can purchase the imported frozen product at ease.
And when the consumer scans the 'code of tracing to freeze', the server acquires the consumer information of the consumer in real time, wherein the consumer information comprises information such as the mobile phone number and the position information of the consumer.
107. And uploading the consumer information to a block chain, and connecting the frozen product information, the dealer information and the consumer information in series to form the chain.
And the server uploads the acquired consumer information to a block chain, associates the consumer information with the frozen product information and the dealer information, further connects the consumer information with the frozen product information and the dealer information in series to form a chain, and takes the consumer information as the last node of the full-chain closed-loop management of the frozen products.
In the embodiment, the method establishes a cold chain food full-link traceability closed-loop management system by relying on the characteristics of distributed storage, transparent information, high autonomy and the like of a block chain technology. Through giving codes to the imported frozen products and scanning the codes, the frozen product information, the dealer information and the consumer information from the import to the selling whole chain of the imported frozen products are uploaded to a block chain, all the information is connected in series to form a chain, and the whole process of product minimum packaging from an enterprise at the first station of the imported frozen products to a consumption link is traced. No matter in which environment the frozen product detects the virus positive, the source of the frozen product in the batch can be traced from the current node to the upper level, and the flow direction of the frozen product in the batch can be traced from the node to the lower level, so that the problems of supervision requirement of quality safety tracing of imported frozen food, important cracking of the problems of scattered tracing data of the frozen product, low data fusion degree, data tampering and the like are solved.
In the embodiment, the ' traceable freezing code ' is scanned by contacting frozen product personnel (dealers, warehouse management personnel, transportation personnel, carriers, consumers and the like) in all links, the server automatically records relevant enterprise information and basic information such as identities, positions and telephones of relevant personnel, once relevant frozen products are checked and found to be problematic, the relevant contacters or relevant persons can be rapidly traced forwards or backwards, the problem that carpet type ' investigation consumes a large amount of manpower and material resources is avoided, and the assisting power is efficient and accurate in epidemic prevention.
