Information storing process comprises the following steps:
(1) as shown in Figure 5, it is suite number that the code figure of tiling is pressed 3 × 3,1 ~ No. 9 (marking in square box), and except all numberings in one group, the upper left corner are indicated, other each group only designates 1 number figure unit; And the 1st bit data of 1 number figure unit is set to 1, and the first bit data of remainder code figure unit is set to 0.
Be suite number according to 2 × 2 pieces again by the code figure unit of tiling, a ~ No. d (marking in circular frame), except all numberings in one group, the upper left corner are indicated, other each group only designates d number figure unit.And the 2nd bit data of d number figure unit is set to 1, and the second data of remainder code figure unit are set to 0.
(2) total information Ms is divided into 9 parts, is stored in No. 1 ~ 9, square numbering respectively; Suppose that total information has 54bit, then each yard of figure unit needs to store 6bit data, is stored in the 3rd to the 8th.
(3) special information Ma is divided into 4 parts, is stored in circular numbering a ~ No. d respectively; Suppose that special information has 12bit, then each yard of figure unit needs to store 3bit data, is stored in the 9th to the 11st.
(4) horizontal information Mx is stored.The Mx information that every two row's code figure unit store is identical.When storing, first according to the position of d number figure unit in 3 × 3 groups in 2 × 2 groups, determine memory code figure unit and the order of Mx.One has three kinds of situations:
1. d position in 3 × 3 groups in the middle of row time, i.e. 4,5 in 3 × 3 groups, when No. 6, Mx is divided into 6 parts and is stored in 1,2 in 3 × 3 groups in order, 3,4,5, No. 6;
2. during the lower row of d position in 3 × 3 groups, i.e. 7,8 in 3 × 3 groups, when No. 9, Mx is divided into 6 parts and is stored in 4,5 in 3 × 3 groups in order, 6,7,8, No. 9;

(5) longitudinal information My is stored.The My information that every two row code figure unit store is identical.When storing, first according to the position of d number figure unit in 3 × 3 groups in 2 × 2 groups, determine memory code figure unit and the order of My.One has three kinds of situations:
1. during middle column in 3 × 3 groups of No. 4 positions, i.e. 2,5 in 3 × 3 groups, when No. 8, My is divided into 6 parts and is stored in 1,2 in 3 × 3 groups in order, 4,5,7, No. 8;
2. during rank rear in 3 × 3 groups of No. 4 positions, i.e. 3,6 in 3 × 3 groups, when No. 9, My is divided into 6 parts and is stored in 2,3 in 3 × 3 groups in order, 5,6,8, No. 9;
3. during prostatitis in 3 × 3 groups, No. 4 positions, the Isosorbide-5-Nitrae namely in 3 × 3 groups, when No. 7, My is divided into 6 parts and is stored in 3,1 in 3 × 3 groups in order, 6,4,9, No. 7;
Suppose that the information that My stores has 12bit, be stored on 6 code figure unit respectively, each yard of figure unit stores 2bit.
By above step, the information that completes stores.According to the data volume supposed in step, the effective information of final each yard of figure unit is 15bit, and its structure is as follows:
Under above tentation data amount, public information Ms is 54bit, can store more than 16 10 system number numberings; Special information Ma is 12bit, can store 0 ~ 4095 numbering; Horizontal information and longitudinal information are all 12bit respectively, if with they memory code figure array place coordinate positions, on the printed article of 30cm × 30cm, the positional precision of storage can be less than 0.1mm.And according to different demands, the size of 4 kinds of quantity of information can be set arbitrarily, or cancel certain information.
(6) according to the final storage information of each yard of figure unit, according to concrete code diagram form, code figure is produced.
Store sample for above information below, recommended information read method is as follows:
(1) quantity of scan code figure, scan code figure should be not less than the size of 3 × 3 code figure unit, and ensures wherein there are 3 × 3 complete code figure unit.
(2) alignment code figure unit, finds 3 × 3 complete code figure unit.
(3) 9 the code figure unit found in read step (2), obtain valid data.
(4) find in 9 code figure unit, valid data first place is the code figure (primitive) of 1.This yard of figure is 1 number figure of 3 × 3 yards of figure arrays.Due to the arrangement mode of 3 × 3 yards of figure arrays, so can 1 number figure cell location 2 ~ 9 number figure unit be passed through.
(5) find in 9 block code figure unit, valid data the 2nd are the code figure unit of 1, more than one of possibility.This yard of figure unit is the d number figure unit of 2 × 2 yards of figure arrays.Due to the arrangement mode of 2 × 2 yards of figure arrays, so necessarily have a left side for a d number figure unit, row that upper left, upper adjacent code figure unit also belong to the 9 block code figure unit found in step (2), be then 2 × 2 yards of figure arrays by this d number and its adjacent code labeling, it is several that possible situation has as shown in Figure 6.
(6) by the Ms part in the effective information of 9 block code figure unit, namely in example, the 3rd bit data, to the 8th bit data, according to the order determined in step (4), is rearranged into complete total information.
(7) by the 9th to the 11st of the valid data in 2 × 2 yards of figure arrays finding in step (5), complete peculiar information is arranged according to the order of a to d number.

(9) according to the ordinal position of the 9 block code figure unit determined in step (4), the d number figure unit position in 2 × 2 yards of figure arrays found in determining step (5).There are three kinds of situations:
If 1. d number figure unit is in 2,5 or No. 8 positions of 3 × 3 yards of figure arrays, then by code figure array 1,2,4,5, the 14th of 7,8 number figure, 15 valid data are arranged in complete My information in order;
If 2. d number figure unit is in 3,6 or No. 9 positions of 3 × 3 yards of figure arrays, then by the 14th of 2,3,5,6,8,9 number figure unit in code figure array the, 15 valid data are arranged in complete My information in order;
If 3. d number figure unit is in 1,4 or No. 7 position of 3 × 3 yards of figure arrays, then by the 14th of 3,1,6,4,9,7 number figure unit in code figure array the, 15 valid data are arranged in complete My information in order.
Information reads complete.
Compared with storing the method for information with existing MPR code, tool of the present invention has the following advantages:
(1) the total information of full storage in MPR code each yard of figure unit, namely on same publication, has duplicate message part in all MPR codes.And under current domestic MPR code standard, total information accounts for the quantity of information ratio of MPR code more than 60%.
And information storage means of the present invention, by the total information in MPR code, dispersed record is in n × m code figure unit, and the quantity of information of each yard of figure shared by total information greatly reduces, thus remains memory space for positional information and other peculiar information.
(2) MPR code quantity of information is limited, at the position mark needing marked index on a small quantity, can only can not provide location coordinate information.And the code figure in the present invention, adopt all standing, seamless arrangement, can represent all location coordinate informations in yard district.
(3) MPR code is when the information of reading, and at least will scan the Ma Tuqu of 2 × 2 sizes, but can only read wherein 1 code figure unit, the information utilization of single sweep operation is 25%.And the present invention is when the information of reading, if establish n=m=2, then at least scan the code district of 3 × 3 sizes, can utilize 2 × 2 block code figure wherein, utilization factor is 44%.If during n=m=3, then utilization factor is 56%.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technology thereof, then the present invention is also intended to comprise these change and modification.
