Embodiment Construction

[0032] Such as figure 1 As shown, the design of a miniature Chinese letter code pattern structure is composed of a position detection pattern 1, a positioning pattern 2, a position detection pattern separator 3, format information 4, coding information 5 and a blank area 6. In order to be unified with the Hanxin code, the position detection pattern 1 of the present invention adopts the image-seeking image of the Hanxin code, and is placed at the top left corner of the micro-mini Hanxin code. The position detection pattern separator 3 is also the same as the Han Xin code, located on the right and lower sides of the position detection pattern. The positioning pattern 2 is composed of black and white unit modules. The positioning pattern 2 on the upper edge starts from the right unit module of the position detection pattern separator 3 to the right edge of the two-dimensional barcode. The first unit module is a black module; The positioning pattern 2 on the left edge starts from the...

Abstract

The invention relates to a generating method for a microminiaturize Chinese sensible code and a symbol thereof. The code picture of the invention consists of a location detecting graph, a location graph, a location detecting graph isolating symbol, format information, a coding area and a blank area. The generating method for the microminiaturize Chinese sensible code includes: coding the information into a data code according to a set rule; generating a corresponding error correcting code to a binary data bit flow accomplished by data coding according to the error correcting mode of a selected error correcting grade; calculating the size needed by a two-dimensional bar code symbol; generating the location detecting graph, generating the format information and setting the location graph. The method has the advantages that the location detecting graph and the distribution structure thereof of the invention have confirmed location information; the bar code symbol is compacter; more effective information can be held in a limited symbol area as much as possible.

Description

Technical field [0001] The invention relates to a two-dimensional bar code symbol and a method for generating it, in particular to a method for generating a miniature Chinese letter code with position detection graphics and positioning graphics and its symbol, belonging to the technical field of automatic identification. Background technique [0002] Bar code technology is a technology that integrates coding, printing, data collection and identification developed on the basis of computer technology and information technology. Common two-dimensional barcodes include PDF417, Data Matrix, MaxiCode, QR Code, and Han Xin code. In addition to representing numbers and symbols, these barcodes also have the ability to represent language and image information in various countries, carry a large amount of information, and accurately describe items. , Anti-counterfeiting function, does not rely on the advantages of computer database, etc., thus improving the application level of bar code tec...
