Embodiment Construction

[0016] Such as figure 1 The binary AB barcode shown is based on the design principle of the one-dimensional code system of commodity barcodes. One is extracted as the main code A, and a sub-code B is derived based on the main code A. The main code A and the sub-code B form a binary code. Meta AB barcode.

[0017] Further, the commodity barcode is an EAN universal commodity barcode. According to the design principle of one-dimensional barcode system, a value in the EAN general commodity barcode is used to extract the output A code, and the B code is output according to the relational expression. Such as:

[0018] (1) EAN—13 yards, B=10 13 +2-A;

[0019] (2) EAN—8 yards, B=10 8 +2-A;

[0020] (3) EAN—128 yards, B=10 128 +2-A;

[0021] The coding derivation process of the code system is applicable to other one-dimensional barcodes. Binary AB barcode can prevent counterfeiting, fill in gaps, and repair damage. The derivation of the coding process is simple and clear, and ...

Abstract

The invention discloses a binary AB barcode. The design principle of one-dimensional codes of a product barcode is taken as the basis, and one one-dimensional code is extracted as a main code A. An auxiliary code B is derived from the main code A which is taken as the basis. The main code A and the auxiliary code B form the binary AB barcode. The relation expression between the main code A and the auxiliary code B is B=10*n+2-A, wherein n is the number of bits of the barcode. Through the combination of the main code A and the auxiliary code B, the main code A and the auxiliary code B depend on each other and compensate for each other, thereby greatly improving the readability and reading accuracy of the product barcode. The binary AB barcode is enabled to have false-proof, vacancy-filling and repairing functions, and a coding derivation process is simple and clear. Moreover, the coding is easy to achieve. The coding derivation process of a code system is suitable for other one-dimensional barcodes, so the binary AB barcode is wide in application range.

Description

technical field [0001] The invention relates to a barcode, in particular to a binary AB barcode. Background technique [0002] The bar code was jointly invented by American Norman Joseph Woodland and his college classmate Bernard Silver, and was patented in the United States in 1952. Barcodes were an advanced invention at the time, as barcode reading technology had not kept up. It wasn't until 22 years after the patent was granted that the barcode made its first appearance in a U.S. store. A barcode or barcode (barcode) is a group of bar and space symbols arranged according to certain coding rules to represent information composed of certain characters, numbers and symbols. The bar code system is an automatic identification system composed of bar code symbol design, production and scanning and reading. It integrates encoding, printing, identification, data acquisition and processing. [0003] Barcode cards are divided into two types: one-dimensional code and two-dimensio...
