Tracing code and check code generation method

Abstract

The invention discloses a tracing code and check code generation method. The method comprises an information code generation process, a check code generation process and a tracing code generation process. The information code generation process comprises the steps of coding product types, production processing batches, delivery batches, a planting base, a quality check flow line and storage information in production links according to generation standards of numbers and English letters, thereby generating independent codes; and according to coding rules, automatically calculating the independent codes according to a calculation formula by a system to generate information codes. The check code generation process comprises the step of generating check codes from the information codes by utilizing a check algorithm, wherein the check codes are numbers or uppercase English letters, and are generated by one-bit numbers. The tracing code generation process comprises the steps of attaching the check codes to the ends of the information codes, taking an integral whole of the check codes and the information codes as a final tracing code, and outputting the tracing code as a graphic symbol identifiable for a code reading device.

Description

[0001] The invention belongs to the field of traceability codes, and in particular relates to a generation method of traceability codes and verification codes thereof. Background technique [0002] At present, there is still the problem of limited traceability links in the traceability of agricultural product quality codes. Although some products adopt two-dimensional code encryption anti-theft technology, once the product leaves the source manufacturer, it enters the information "black box" again, and the information on the "ID card" is incomplete. How to build a quality traceability system and transparently present the information of each link of agricultural products from the field to the supermarket shelf is a good way to solve the problem. In reality, the chain of traceability of the quality of agricultural products has not been fully opened up, and there are still many blocking points. Patent application number: 201310475565.0 "A Unified Coding Method for Perceptual Obj...

Problems solved by technology

The production area of ​​traditional Chinese medicinal materials is scattered and the number of subjects is large, so it is difficult for producers to afford the huge traceability investment; from the perspective of the production chain of medicinal materials, the production, processing, circulation and other links are still in a state of separation, and the information cannot be fully connected, and it is difficult to achieve full traceability; even Various varieties and production areas have various standards and are incompatible with each other, which also brings troubles to producers and consumers
