Variable quick response code based whole-course credible tracing-back system for quality safety of agricultural product

Abstract

The invention relates to a variable quick response code based whole-course credible tracing-back system for the quality safety of an agricultural product. A variable quick response code label is generated, agricultural product information is collected and stored in a database, the database is connected to an agricultural product safety tracing platform, and the variable quick response code label is printed on an external package of the agricultural product; agricultural product safety tracing equipment reads and decodes the variable quick response code label in the plantation, transport, pesticide residue detection, processing, packaging and sales links of the agricultural product, and decoding data and user data are uploaded; the agricultural product safety tracing platform receives the uploaded decoding data and user data, and a matching result is returned to the agricultural product safety tracing equipment. The different manufacturing links of the agricultural product are monitored, traced back and managed transparently by utilizing advantages of higher tolerance and anti-falsification of the variable quick response code, the credibility of the whole quality safety tracking and back tracing process of the agricultural product is improved, and the monitoring workload of the government is reduced.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a whole-process credible traceability system for the quality and safety of agricultural products based on variable two-dimensional codes. Background technique [0002] Two-dimensional code anti-counterfeiting labels include ordinary two-dimensional codes and variable two-dimensional code anti-counterfeiting labels, among which variable two-dimensional code anti-counterfeiting is a very high anti-counterfeiting technology, which can help enterprises better realize the combination of marketing and anti-counterfeiting function. Variable two-dimensional code anti-counterfeiting features: a wide range of encoding, the barcode can encode pictures, sounds, text, signatures, fingerprints and other digitized information, expressed in barcodes, can represent multiple languages, and can represent image data ; Strong fault tolerance and error correction function, which makes the two-d...

Problems solved by technology

However, the existing anti-counterfeit traceability system for agricultural products based on QR codes is mainly based on ordinary QR codes, and from the perspective of the agricultural product industry chain, the anti-counterfeit traceability of agricultural products can be traced back to the initial planting of agricultural products, and the government is faced with the problem of pesticide residues in agricultural products. There is a lack of effective agric
