Example Embodiment

[0030] The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0031] The present invention uses batches as the traceability unit. The same batch refers to products of the same variety produced by the same responsible subject at the same time. Considering that the certification type is more important to the quality and safety of agricultural products, the code is composed of the origin location code, product code, and production code. It is composed of date code and authentication type code.

[0032] The agricultural product traceability code encoding method of the present invention specifically includes the following steps:

[0033] S1. According to the latitude and longitude values ​​of the origin of agricultural products, generate a 1-digit location identification code and a 10-digit origin location code

[0034] The origin location code is composed of 13 digits, of which the longitude occupies 7 digits, the la...

Abstract

The invention relates to a method for coding tracing codes of agricultural products. The method comprises the following steps: generating one position identifying code of agricultural products and ten position codes of a manufacturing location; generating five product codes of agricultural products; generating one date identifying code of agricultural products and three production date codes; generating one authentication type code of agricultural products; generating two identifying codes of agricultural products; generating tracing codes of agricultural products; and printing the tracing codes of agricultural products generated on the relevant carrier and attaching an outer packing of agricultural products. The encoding scheme designed in the invention is difficult to indicate indicial meanings upon the figure composition, the length is shorter, and the encryption is better; during the product tracing, under the condition of separating from a database, the coding method can trace geographical positions of information close relevant to quality security of agricultural products enterprises, production dates and product authentication types and the like, so as to lay the foundation of accurate positioning to the enterprise and rapid taking emergency measures during generating the problem of quality security of agricultural products.

Description

technical field [0001] The invention relates to an agricultural product traceability code encoding method based on geographic coordinates and multiple encryption, belonging to the field of agricultural product traceability. Background technique [0002] Establishing an agricultural product traceability system and promoting the establishment of my country's agricultural product safety system are important means to ensure the safety of consumers' edible agricultural products and enhance the competitiveness of my country's agricultural products. The unified code is the basis for realizing the traceability system of agricultural products. [0003] Regarding the research on traceability code coding, the EAN.UCC system (Global Unified Identification System) is often used abroad to track and trace the production process of agricultural products. The EAN.UCC system is jointly developed, managed and co The global unified marking system and common business language maintained by the ...
