Description
Technical Field
The invention relates to the technical field of modern agricultural management, in particular to a block chain agricultural product tracing method based on Beidou grid codes.
Background
With the improvement of the economic level of China, people have higher and higher requirements on the quality and safety of agricultural products. On the one hand, we should continue to increase the domestic agricultural production level to meet the needs of people for the quality and quantity of agricultural products. On the other hand, when an agricultural product security event occurs, the supervision department needs to quickly and accurately find out the problem and perform the responsibility following and correction. It is therefore particularly necessary to establish an efficient, reliable, disclosed agricultural product traceability system.
The currently used tracing system depends on a centralized data storage technology, when tracing agricultural products, the whole industrial chain of the production of related agricultural products is often involved, and a plurality of enterprises and responsible persons are involved, so that the tracing system is not beneficial to the rapid investigation of a supervision organization. Meanwhile, when acquiring production and transportation information of agricultural products, the supervision authorities rely on the product production information provided by related enterprises; the information is difficult to distinguish true from false, and the tracing of agricultural products is difficult.
Disclosure of Invention
In order to solve the problems, the invention provides a method for tracing agricultural products by using a blockchain based on Beidou grid codes, which introduces the blockchain and records the cultivation and sales data of the agricultural products by utilizing the advantages of the blockchain, such as decentralization, disclosure transparency, non-falsification and trust; meanwhile, beidou grid codes are introduced, beidou grid codes are carried out on the crop growing plots, identification codes corresponding to crops are formed, and accurate positioning of crop cultivation information and responsible persons is achieved; helping the supervision department to rapidly and accurately finish tracing the agricultural product safety problem.
The invention adopts the following technical scheme:
a blockchain agricultural product tracing method based on Beidou grid codes comprises the following steps:
(1) Establishing public chains which are open to the public of society, alliance chains which are open to the whole industry chain of agricultural products and private chains which are used by enterprises and regulatory departments of the industry chain of agricultural products respectively; the alliance chain, the public chain and the private chain are connected through a cross-chain technology;
(2) Enterprises of the agricultural product industry chain respectively upload production data, management and control key points and relevant responsible person information in the processes of producing, processing and transporting the agricultural products to private chains controlled by the enterprises; the agricultural product production enterprises code the agricultural product planting plots by a Beidou navigation system through Beidou grid codes to obtain identification codes which are in one-to-one correspondence with the agricultural product planting plots with a certain area; recording growth data of the agricultural product growing process by taking the agricultural product planting land block corresponding to the identification code as a unit; and store in the private chain controlled by agricultural product production enterprises; the supervision department uploads the supervision and inspection records to the private chain controlled by the supervision department;
(3) Establishing an underlying system supporting intelligent contracts and corresponding intelligent contracts; enterprises of the agricultural product industry chain upload inter-enterprise transaction data and records and production plans to the alliance chain; the supervision department uploads the public working content and supervision requirements to the alliance chain; enterprises and regulatory departments of the agricultural product industry chain inquire information in the alliance chain through intelligent combination;
the public chain is commonly maintained by enterprises, regulatory authorities and the public of the agricultural industry chain; enterprises of the agricultural product industry chain upload enterprise brand construction contents to the public chain, and the supervision department uploads supervision public work contents to the public chain;
(4) An application client and a transaction website based on a blockchain are established.
Further illustrative of the present invention, federation chains, public chains, and private chains are connected by distributed private key control techniques in a cross-chain technique. The distributed private key control technology adopts a general cross-chain protocol and a distributed account book for recording cross-chain transactions and intra-chain transactions, so that connection and transfer among different block chains are realized.
According to the invention, when the Beidou grid codes are adopted to code the agricultural product planting plots, the Beidou position grid codes which are in one-to-one correspondence with the crops are formed by taking the plot space required by the growth of single crops as a unit according to the type of the planted agricultural products, and cultivation information, management and control key points and related responsible persons in the agricultural product growth process are recorded; and taking the Beidou grid code as an identification code corresponding to the crops and the growth data thereof, carrying out hash operation, and storing the hash operation into a block chain.
Further describing the invention, the intelligent contract coordinates funds and material transactions among enterprises of the agricultural product industry chain and supervision of the enterprises by the supervision department.
The invention has the advantages that:
according to the invention, by introducing the blockchain, the cultivation and sales data of agricultural products are recorded by utilizing the advantages of the blockchain, such as decentralization, disclosure transparency, non-falsification and trust; a private chain, a alliance chain and a public chain are respectively established by utilizing a cross-chain technology; the private chain is convenient for the enterprise to manage and record data, so that the reliability of the data can be ensured, and the business confidentiality of the enterprise can be ensured not to be revealed; the alliance chain is convenient for the supervision department to supervise the enterprise production and efficiently and safely complete transactions among enterprises; meanwhile, the invention also introduces the Beidou grid code, carries out the Beidou grid code on the crop growing plots to form the identification code corresponding to the crops, and realizes the accurate positioning of the crop cultivation information and the responsible person; helping the supervision department to rapidly and accurately finish tracing the agricultural product safety problem.
Detailed Description
The invention will be further illustrated with reference to specific examples.
Example 1:
a blockchain agricultural product tracing method based on Beidou grid codes comprises the following steps:
