Abstract
The utility model discloses a kind of two-dimensional matrix point horizontal and vertical parity check code based on BCD codings, including direction code, code text unit and check code, the direction code, code text unit and check code are the lattice structure component of 2x2 a kind of, the literary unit of code is located at the side of direction code, the code text of the literary unit of code is digital zero to numeral nine, check code is located at the side of code text unit, and check code is drawn by direction code and code text unit summation operation.The two-dimensional matrix point horizontal and vertical parity check code encoded based on BCD, can according to the actual requirements increase and decrease, adjusts and deform, and the code text for being suitable for various complex conditions applies quarter, detection demand；And because check code has uniqueness, two code text units or one code text unit of combination and check code are combined, the identification direction of code text is not interfered with, makes it have certain mistake proofing error correcting capability.
Description
Technical field
It the utility model is related to barcode technology field, especially a kind of two-dimensional matrix point horizontal and vertical parity check code based on BCD codings.
Background technology
Barcode technology is to realize POS system, EDI, ecommerce, the technical foundation of supply chain management, is that logistics management shows
The important technical of generationization.Barcode technology includes the coding techniques of bar code, the design of bar code mark symbol, fast recognition technology
And computer management technology, it is to realize computer management and the indispensable front-end collection technology of electronic data interchange.Bar code skill
The most frequently used bar code includes bar code, Quick Response Code etc. in art.
Bar code (Barcode) is the multiple secret notes and blank for not waiting width, is arranged according to certain coding rule, is used
To express the graphical identifier of a group information, common bar code is the secret note to be differed greatly by reflectivity（Abbreviation bar）And informal voucher
（It is referred to as empty）The pattern of parallel lines lined up.In complex environment, bar code is carved as applied during heat treatment of workpieces, due to workpiece heat
Swollen shrinkage, easily cause the adhesion between secret note, influence subsequently to identify；And bar code is arranged in one direction all the time,
It greatly limit it and apply quarter position.
Quick Response Code（QR Code）More information can be deposited than traditional bar code, more data types can be also represented, be
With certain specific geometric figure according to certain rules in plane（On two-dimensional directional）The chequered with black and white graphic recording data of distribution
Symbolic information；On coding dexterously using form " 0 " of computer-internal logical foundations, " 1 " bit stream concept,
The geometrical body corresponding with binary system using several represents word numerical information, is swept by image input device or photoelectricity
Equipment automatically identifying and reading is retouched to realize that information automatically processes.Because two-dimension code structure is complicated, apply needs more times during carving, and
For different workpiece, because painting is carved, position is not of uniform size, and code text size, shape can all receive larger limitation, and when code text is smaller
When, it identifies that difficulty is bigger.
The content of the invention
The purpose of this utility model is to provide a kind of two-dimensional matrix point horizontal and vertical parity check code based on BCD codings, simple in construction, can know
Other property is high, to solve the problems, such as in above-mentioned background technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of two-dimensional matrix point horizontal and vertical parity check code based on BCD codings, including direction code, code text unit and check code, the direction
Code, code text unit and check code are the lattice structure component of 2x2 a kind of, and code text unit is located at the side of direction code, code Wen Dan
Member code text for digital zero to numeral nine, check code is located at the side of code text unit, and check code passes through direction code and code text unit
Summation operation is drawn.
As further program of the utility model：The code text unit is converted to by binary-coded decimal corresponding to numeral.
As further program of the utility model：The direction code is different from code text unit and check code, and with only
One property.
Compared with prior art, the beneficial effects of the utility model are as follows：
The two-dimensional matrix point horizontal and vertical parity check code encoded based on BCD, can according to the actual requirements increase and decrease, adjusts and deform, be suitable for
The code text of various complex conditions applies quarter, detection demand；And because check code has uniqueness, it is combined two code Wen Dan
Member or one code text unit of combination and check code, do not interfere with the identification direction of code text, make it have certain mistake proofing and entangle
Wrong ability.
Brief description of the drawings
Fig. 1 is code text unit of the present utility model and decimal numeral corresponding relation；
Fig. 2 is basic structure and layout of the present utility model；
Fig. 3 is a kind of deformation layout of the present utility model.
In figure：1 direction code, 2 yards of literary units, 3 check codes.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1-3, in the utility model embodiment, a kind of two-dimensional matrix point horizontal and vertical parity check code based on BCD codings, including side
To code 1, code text unit 2 and check code 3, direction code 1, code text unit 2 and check code 3 are the lattice structure component of 2x2 a kind of,
Direction code 1 is different from code text unit 2 and check code 3, and has uniqueness so that any combination two code text units 2 or
A code text unit 2 and check code 3 are combined, does not interfere with the identification direction of code text, code text unit 2 is located at the one of direction code 1
Side, and code text unit 2 is the lattice structure component of 2x2 a kind of, the code text of code text unit 2 is turned by binary-coded decimal corresponding to numeral
Digital zero is got in return to numeral nine, so that its structure prevents dot matrix blank, strengthens identifiability, check code 3 is located at code Wen Dan
The side of member 2, check code 3 are drawn by direction code 1 and the summation operation of code text unit 2, so as to the correctness of detection code text
Or the code text that amendment part is misread.
The two-dimensional matrix point horizontal and vertical parity check code encoded based on BCD, can according to the actual requirements increase and decrease, adjusts and deform, be suitable for
The code text of various complex conditions applies quarter, detection demand；And because check code 3 has uniqueness, it is combined two code texts
Unit 2 or combination one code text unit 2 and check code 3, the identification direction of code text is not interfered with, make it have certain anti-
Wrong error correcting capability.
In summary：The two-dimensional matrix point horizontal and vertical parity check code based on BCD codings, it is simple in construction, identifiability is high, it is certain to have
Mistake proofing error correcting capability, effectively solve the problems, such as that the smaller resolution of code text is lower.
