Two-dimensional code with positioning function

Abstract

The present invention discloses a two-dimensional code with a positioning function. The two-dimensional code comprises a code body and is characterized in that one side of the code body is provided with a graphical region, the other side of the code body is sequentially provided with a sequence number region, a product lot number, a dispensing lot number and a data identifier region; the two-dimensional code is simple in structure and convenient to manufacture, and adopts a unified specification, and can be conveniently used on a packing box; and the printing quality of the two-dimensional code conforms to an ANSI (American National Standards Institute) standard, has an automatic alarming apparatus with prompt information, so that paper boxes that do not conform to the standard can be accurately and rapidly removed. According to the two-dimensional code with the positioning function disclosed by the present invention, each link, from production of products to sale of the products, has trackability and traceability functions; while the quality is guaranteed, some counterfeits are eliminated; and the two-dimensional code occupies less space, is transported in a spreading way, saves transportation cost, is novel in design, and is easy to promote and use.

Description

technical field [0001] The invention relates to the field of coding technology, in particular to a beautiful and practical two-dimensional code with a positioning function. Background technique [0002] The so-called two-dimensional code is to record data symbol information with a specific geometric figure distributed in the two-dimensional direction according to a certain rule; "0", " 1" The concept of bit stream, using several geometric shapes corresponding to binary to represent text and numerical information, automatically read through image input equipment or photoelectric scanning equipment to realize automatic information processing. Two-dimensional code can be used in both horizontal and vertical Azimuth expresses information at the same time, so a large amount of information can be expressed in a small area. Stacked 2D barcodes are also called stacked 2D barcodes or layered 2D barcodes. The coding principle is based on the 1D barcodes, which are stacked into two or...

Problems solved by technology

[0003] However, one-dimensional codes are mostly used in the market at present. One-dimensional codes are marks composed of a group of regularly arranged bars, spaces and corresponding characters. At present, they are widely used in computer applications and practice. An automatic identification technology in the fields of commerce, postal services, library management, warehousing, industrial production process control, transportation, etc. It has the advantages of fast input speed, high accuracy, low cost, and strong reliability. It occupies an important position in today's automatic identification technology. Relatively important position, but there are still many deficiencies, it does not have a positioning function, it is not suitable for use on some important medicines, so it has certain limitations, and the safety performance is not perfect
