Embodiment Construction

[0048] Hereinafter, the present invention will be described in detail by illustrating various exemplary embodiments of the invention with reference to the accompanying drawings. However, inventive concepts may be embodied in many different forms and should not be construed as limited to the illustrative embodiments set forth herein. Furthermore, the same reference numerals may be used to denote similar elements in the drawings.

[0049]Embodiments of the present invention provide a barcode structure, decoding method and decoding device. In the barcode structure of the present invention, each character is composed of 3 black bars (Bar) and 3 white bars (Space), or is composed of 2 black bars and 2 white bars. Each black bar has a different width than each white bar, with the thickest being 4 times the width of the thinnest. Accordingly, one data code of the barcode of the present invention can have an information volume of 8 bits. Therefore, based on the same printing length...

Abstract

The invention provides a bar code structure, a bar code decoding method and a bar code decoding apparatus. A data number of a bar code can have 8-bit information content. Therefore, in a situation of the same print length based on a Code 128, the information density of the bar code can be increased, and coding and subsequent operations can be simplified at the same time. Moreover, the bar code of the invention can be arranged horizontally on a plane of an object, arranged circularly on a plane of a round disc, or arranged circularly on an annular side surface of a cylinder. In this way, the decoding apparatus identifies a data number that can express 8-bit data in the bar code by a corresponding rectilinear motion or by rotating the round disc or the cylinder.

Description

technical field [0001] The present invention provides a barcode structure, a decoding method and a decoding device, in particular to a barcode structure capable of representing 8-bit data, and a decoding method and a decoding device matching the structure of the barcode. Background technique [0002] Many products on the market use Code 128 as the standard for making one-dimensional barcodes. However, for barcodes with limited space that require more data, general-purpose barcodes are no longer sufficient. [0003] For example, a one-dimensional barcode is printed on the reagent disk consumables of medical instruments to provide the information required for the detection and calculation process. Among the commonly used one-dimensional barcodes, the one with the highest information density is the Code 128 barcode generated by the Code 128 encoding method. In this Code 128 barcode, each character is composed of three black bars (Bar) and three white bars (Space). The sum of...
