Agri-product two-dimensional code traceability system solution

Introduction: Agricultural products “from farmland to table” are both an entity's manufacturing and delivery process and an information production and delivery process. Producers need market information for production, regulators need production information for supervision, and consumers need product information for selection.


China is a big country in agriculture, but agricultural development is struggling, and the issue of agricultural product safety is often reported. Although the management departments actively take measures to strengthen management and supervision in all aspects, the effect has been unsatisfactory. On the one hand, it is difficult for consumers to know the “previous and present life” of agricultural products, and they cannot have a sense of trust in agricultural products. On the other hand, some false reports cause incalculable losses to the producers of agricultural products. The phenomenon of farmer pit farming has repeatedly occurred. To this end, Yiyi Internet has developed a traceability system for agricultural products based on two-dimensional code technology. The system focuses on the process of planting, producing, processing and selling agricultural products. This not only guarantees the quality and safety of agricultural products, but also abolishes consumer concerns. It is also an agricultural producer. The supervision and support. It can be said that the traceability system is an important application for solving agricultural product safety issues and promoting agricultural development.


Agricultural products “from farmland to table” are both an entity's manufacturing and supply process and an information production and delivery process. Producers need market information for production, regulators need production information for supervision, and consumers need product information for selection. The reverse conduction of information at the mid-end and terminal can directly influence the behavior choices of producers. This shows that information is important for quality control of agricultural products. In terms of information supply, the Internet has unparalleled advantages in other ways. Through the establishment and improvement of traceability systems, consumers' confidence in agricultural products is enhanced. The use of information technology to carry out all-dimensional packaging of high-quality agricultural products, increase the credibility of agricultural products sales to serve more consumers. The transparency and openness of information on agricultural products will be resolved, current food safety issues will be resolved, and customers’ concerns about the safety of agricultural products will be dispelled.


Agri-product two-dimensional code traceability system solution


First, the application of two-dimensional code technology


The two-dimensional code is mainly used in this system for the traceability of agricultural products from the place of production, product growth environment (ie, selection, fertilization, and medication in production), testing, and sales. At present, the coding and decoding technologies of two-dimensional codes are publicly available. Therefore, it is necessary to overcome the problems that two-dimensional codes are easy to copy and difficult to prevent. To this end, the Easy Internet of Things uses asymmetric key technology to encrypt and decrypt information to solve the above problems. The encrypted two-dimensional code must read the corresponding information through the corresponding decryption algorithm and the public key. Otherwise, it is a Stacked garbled, which to a certain extent guarantee the security of the use of two-dimensional code.

Second, the program design of traceability system of agricultural products


2.1 Traceability management of agricultural products The integrated system is the core system of the traceability system and is the storage and processing center for all data.


Through this system, information on the cultivation process of local agricultural products can be digitized; the quality supervision department supervises the production process of agricultural products; and the mature agricultural products are sampled and inspected; the actual reliability of the production process is further confirmed through the data; To endorse the book so that consumers have enough trust in agricultural products, enhance consumer confidence; consumers finally through the mobile phone two-dimensional code, convenient and efficient query of agricultural information.


2.2 Plant Information Management System


Planting information management system is the foundation of the whole traceability management and construction. It is the key link of traceability management. The authenticity and effectiveness of this part of the data are related to the success or failure of the traceability process. The main function of this system is to record detailed information on the production of agricultural products (such as the origin of products, sowing, seedlings, fertilization, irrigation, pest control, and harvest time, etc.), and to informatize the production process of agricultural products to create an “electronic for each agricultural product”. "Files" record the entire process of their production and store the recorded information in the database of the traceability management system of agricultural products to facilitate future inquiries. At the same time, encryption technology can be used to encrypt information through a private key to generate a two-dimensional code label for each batch of agricultural products that pass the sampling inspection, and record the production process information of the agricultural product in the label; no inspection, inspection or inspection is not required. Qualified products cannot generate two-dimensional codes, and cannot use agricultural product traceability two-dimensional code tags.
