(2) number 0: the diamond shape code word formed for the ease of identification, the present invention using 4 dots shown in code word 2 in Fig. 6
Indicate number 0；
(3) for Quick positioning map shape data name code area, the origin identification of code area can origin identification position: be defined
Position.The present invention is indicated using shown in code word 1 in Fig. 6 by the up-side down triangle code word that 3 dots form.Without loss of generality, such as
A string of code words of fruit code area, it is also possible not define origin identification position；
(4) English alphabet: it can about be scheduled in graphic documentation name using specific English alphabet, capitalization is such as used only
A~I, and specific position uses in graphic documentation name, the particular meanings such as expression data version, space of a whole page.Once defining
Specific position centainly uses English alphabet in graphic documentation name, then English alphabet and digitally coded all or part of can be achieved
Multiplexing, without will cause decoding error.In Fig. 6, capitalization English letter A~I is multiplexed respectively at number 1~9.Based on Fig. 6,
It can arrange, code word 7 occur in the specific position of graphic documentation name, can directly decode as English alphabet E, rather than be decoded as counting

Blind round hole or circular printed pattern are also possible to through-hole, blind hole or the printed pattern of other shapes.
2, the deformation constraint of code word
The graphic documentation name code word indicated using mahjong " cylinder " font is similar to, there may also be some variations.Specifically
Version includes but is not limited to following several:
(1) one is deformed: the rotation, mirror image, spacing scaling, projective transformation etc. of basic mahjong " cylinder " font；
(2) two are deformed: on the basis of basic mahjong " cylinder " font, keeping points constant, and changes the topological shape of point；
(3) three are deformed: on the basis of basic mahjong " cylinder " font, both having changed points, and had also changed topological shape a little；
(4) four are deformed: on the basis of above-mentioned 1,2,3 one or more constraints, using any other base in addition to dot
This shape (such as triangle, square, rectangle, diamond shape, pentagon), to indicate code word element.
For the supplementary explanation of deformation one: code word 1~11 shown in fig. 6 carries out any one code word any
Perhaps horizontal mirror image (left and right overturning), vertical mirror (spinning upside down) operate or carry out code word element to the rotation process of angle
The amplification of spacing, reduction operation, code word layout obtained, think equivalent with corresponding codewords shown in fig. 5.
As shown in fig. 7,7 (a) be 5 prototype of code word shown in fig. 5,7 (b), 7 (c) respectively indicate code word 5 rotate to be it is vertical and
Flat shape, 7 (d) expression code words have carried out horizontal or vertical mirror image, and the spacing of 7 (e) the expression each dot elements of code word 5 carries out
It reduces.The new code word shape that these deformations are obtained, it is equivalent with code word 5 shown in fig. 5.Without loss of generality, code word 5 may be used also
To have other similar rotation, mirror image, scaling deformation result.Similarly, other code words can also carry out equivalent rotation, mirror
Picture, scaling deformation operation.
For the supplementary explanation of deformation two: code word 1~11 shown in fig. 6 carries out any one code word equal
Topological shape under dot element changes code word layout obtained, thinks equivalent with corresponding codewords shown in fig. 6.
As shown in figure 8,8 (a) be 7 prototype of code word shown in fig. 6, other than 8 (b) expression code words 7 rotate to be flat shape,
Other 8 (c), 8 (d), 8 (e) expressions have carried out the change of topological shape to code word 7.The new code word shape that these deformations are obtained
Shape, it is equivalent with code word 7 shown in fig. 6.Without loss of generality, code word 7 can also have other similar topological shape to change knot
Fruit.Similarly, other code words can also be laid out the change of shape in the case where number of elements is constant.
For the supplementary explanation of deformation three: code word 1~11 shown in fig. 6 carries out element for any one code word
The change of quantity and topological shape code word layout obtained, it also hold that equivalent with corresponding codewords shown in fig. 6.
As shown in figure 9,9 (a) be 3 prototype of code word shown in fig. 6, this code word 3 is characterized using dot, when being imaged
And identification it is bad when, once dot identification is less than be easy to causeing the missing inspection of code word 3.If we are using layout shown in 8 (b)
10 dots characterize code word 3, then to detect effect and code word correct recognition rata will greatly improve.In advance arranged by this
The new code word shape that mode changes code word element quantity and topological shape is obtained, it is same it is considered that with code shown in fig. 6
Word 3 is equivalent.Without loss of generality, code word 3 can also have other similar topological shape to change result.Similarly, other code words
It can also carry out the change of number of elements and topological shape.
For the supplementary explanation of deformation four: code word 1~11 shown in fig. 6, for wherein one or more code words, by its base
This component replaces with other fundamental figure shapes, such as triangle, square, rectangle, diamond shape, pentagon by dot,
Thus code word layout obtained, it also hold that equivalent with corresponding codewords shown in fig. 6.
As shown in Figure 10, code word element is changed to square by dot, the code word obtained thinks and corresponding true form word
It is equivalent.
3, multiple code word space layout designs
Since a graphic documentation name is generally formed by multiple codeword codings, on the basis of code word design, also need
Carry out the space layout design of multiple code words.
Preferably, a string of code words for meeting graphic documentation naming rule are arranged one by one according to horizontally or vertically mode,
And code area is laid out as far as possible in plate member edge, and multiple code word arragement directions are parallel to the plate member edge closed on as far as possible, keep away
Exempt to have an impact pcb board printing zone.
The concrete application scene of the rule are as follows: it suppose there is an electrical patterns data, when not considering its extension name,
Arrange the entitled 2683B0_A of its graphic documentation.The graphic documentation name does following constraint: the 1st~4 and the 6th bit word are number
Word the 0~9, the 5th, 8 bit words are English alphabet A~G, and the 7th bit word is spcial character (underscore " _ ")；It constrains simultaneously: by this
Each code word of coding sequentially arranges in the horizontal direction, and obtained coding is as shown in figure 11.Wherein, first, left side code word is
Origin identification position represents the starting point for having found code area when detecting the code word；Code after origin identification position
Word is each coding codeword of graphic documentation name.
Coding zone position of the graphic documentation name 2683B0_A on pcb board part, is shown in Fig.12, close to a left side for plate
Inferior horn fringe region can effectively avoid intermediate PCB figure printing area, while imaging device also being facilitated to carry out code area
It takes pictures.Without loss of generality, graphic documentation name coding zone position can be in any position of pcb board part edge.
The constraint rule uses the arrangement design in mahjong hole, and combines the mode of vertical setting of types or horizontally-arranged arrangement, discharges with diagonal
Or multirow discharge is compared, and has fool-proof design, identification error rate can be reduced in practical application.
The identification of 3 graphic documentation name of embodiment, graphic documentation retrieval and application method
On the basis of the coding rule of the system composed structure of embodiment 1 and embodiment 2, a set of carry out figure is designed
The method of the identification of data name and graphic documentation retrieval and application.This method uses camera, grabs the figure on pcb board part
The image of data name code area is positioned and is identified by computer that each code word of graphic documentation name strings, forms figure
Data name；Go retrieval that there is the PCB graphic documentation of the graphic documentation name in graphic documentation storage unit, and by the PCB figure
