Embodiment 1
With reference to Fig. 1, a certain raw information, this information waiting for transmission has category attribute, and described information is made up of the contents fragment of different classes of attribute, needs to be reduced into raw information at last or to carry out other efficient processing by two-dimensional bar code intermediary.Whole information exchanging process divides before the exchange and latter two stage of exchange.
At first, set up the classification table between different category attributes and the numbering, the template table commonly used between different attribute information and the template numbering;
The second, we will analyze raw information, be broken down into the appropriate information fragment according to character, and separate with separator; Information segment is classified, concludes these classification again, and classification of different nature is numbered respectively, as A, B, C ... (this just for example, is not particularly limited and only uses these letters, also can use other symbolic representation)
The 3rd, according to the information segment sorting technique, all information segments are included into respective classes, according to the order of information segment in raw information the classification numbering is got up by this series arrangement again, be expressed as a character string, as ABCBBC, again this character string to be simplified, the method for simplification has 2 kinds:
1, pays close attention to order information for needs, the continuous identical category numbering that (comprises 2) more than 2 is merged successively by the front and back order, the multiplicity numeral, ABCBBC → ABC2BC then, the character string after the simplification is exactly classification and the order information (to call attribute information in the following text) that extracts.
2, for not needing to pay close attention to order information, because classification order can free arrangement, the identical category numbering that (comprises 2) more than 2 is merged the multiplicity numeral, ABCBBC → A3B2C then, the character string after the simplification is exactly the classification information (being attribute information) that extracts.
For the attribute information of frequent use, we have better method that above-mentioned attribute information is further simplified again.This attribute information is defined as another simpler character combination (this simpler character combination is to call the template numbering in the following text), as ABC2BC → MB1 (also can use other symbolic representation), and this definition is told the identification link of back, make the identification link of back also can know the implication of template numbering MB1, the result will be more succinct so.
These two little steps are not conflicted, and can only use till the attribute information, can be simplified to the template numbering always yet, perhaps both are combined application, and this must see demand and decide.Because template is concentrating again attribute information, have only identical attribute information just can use same template, so also can lose dirigibility when introducing template, only be that the difference of arranging can not be used same template, this will cause the increase of template number, so different occasion can take different step array modes to reach optimal effectiveness.In the narration of back, the method for template numbering and the method for a use attribute information will be described respectively, but practical application can also be carried out applied in any combination also more than that.
The 4th, the template numbering (or attribute information) that extracts is placed on the front, put behind being separated the raw information that symbol is separated into information segment, middle with identical separator separation, remove the redundant information of describing about classification in the information segment, just constituted a character string, as MB1 with set form; 123; 456; 789; 564; 645; 789 (or ABC2BC; 123; 456; 789; 564; 645; 789) (use here "; " as separator, also can use other symbol, content is represented with 123 here, also can use other character representation).
The 4th, convert above-mentioned character string to two-dimensional bar code by the two-dimensional bar code coding rule with set form.
The 5th, two-dimensional bar code is decoded, extract character string wherein, as MB1; 123; 456; 789; 564; 645; 789 (or ABC2BC; 123; 456; 789; 564; 645; 789).
The 6th, template numbering (or attribute information) and content in the separating character string.
The 7th, explain form and order information from the template that extracts numbering (or attribute information), then form and order information are corresponded to one by one information segment separately, preserve these information, go forward side by side the Xingqi its handle, comprise the raw information state that is reduced into.
With reference to Fig. 2, a kind of code device of realizing described method for transmitting information based on two-dimensional bar code comprises two-dimensional bar code coding device 5, and this information waiting for transmission has category attribute, and described information is made up of the contents fragment of different classes of attribute; Described code device also comprises category attribute and corresponding sorted table 1, the information segment typing module 2 of numbering, be used for attribute information module 3 that the order according to the information segment typing is arranged in order numbering, be used for attribute information and each information segment are formed the information module 4 that prelists of set form character string, the output connection two-dimensional bar code coding device 5 of the described information module 4 that prelists.
Described code device also comprises the corresponding template table commonly used 6 of attribute information and template numbering, be used for the attribute information that will set is defined as the template numbering module 7 of template numbering according to template table commonly used, and the described signaling module 4 that prelists is with template numbering and each information segment composition set form character string.

With classification numbering extract in order into:
ABCDEHI
The continuous identical category numbering that (comprises 2) more than 2 is merged, and it is as follows that multiplicity is reduced to attribute information with numeral:
ABCDEHI → ABCDEHI (not having to find that continuous identical category numbering is arranged) so do not simplify
Because be the form that often uses, it is as follows that we can be defined as above-mentioned attribute information the template numbering:
ABCEDHI→MB 1
Template Information is tabulating as following table 2:
Template table:
| Sequence number | The template numbering | Attribute information |
| 1 | MB1 | ABCDEHI |
Table 2
Template numbering is arranged in order by front and back in proper order with content (removing the text description of attribute) is in the same place, middlely separate with separator, formation set form character string is as follows:
MB1; V628; Company limited of Motorola (China); On March 20th, 2005; 02-0010-042968; CDMA; 32E456763; 2004CD2234
Can convert above-mentioned two character strings to two-dimensional bar code according to the two-dimensional bar code generating mode of standard with that.
The process that receives is exactly an opposite process, and when terminal device scanning two-dimension bar code and recognition, the character string that decodes set form is as follows:
MB1; V628; Company limited of Motorola (China); On March 20th, 2005; 02-0010-042968; CDMA; 32E456763; 2004CD2234
Separate template numbering (MB1) and content in the above-mentioned character string, and learn MB1=ABCDEHI (attribute information) according to the Template Information that defines in the exchange front template table;
After obtaining attribute information, according to the classification that defines in the classification table before the exchange attribute information is corresponded to separately content one by one, it is as follows that generation possesses the context string (corresponded manner of attribute information and content can be various, and this just exemplifies wherein a kind of) of attribute information:
A=V628; Company limited of B=Motorola (China); C=2005 March 20; D=02-0010-042968; E=CDMA; H=32E456763; I=2004CD2234
The above-mentioned context string that possesses attribute information has been arranged, and terminal device just can carry out multiple processing to it, comprises the state that is reduced into raw information and to other processing of data.
Arrive here, the coding method of utilization Template Information just is through with the information of mobile phone by the process that two-dimensional bar code intermediary is distinguished and handles by infosystem.In this process, use method of the present invention to guarantee the efficient processing of cellphone information at subsequent process, the two-dimensional bar code of Sheng Chenging is minimum simultaneously.
In this process because do not need to pay close attention to sequential attribute, so attribute order can free arrangement, with regard to can not be useful template and the problem that causes template number to heighten, so the utilization template is reasonable way in this case.
With reference to Fig. 1, Fig. 2, the information on Fig. 3, Fig. 4 business card is distinguished and is handled by terminal device by two-dimensional bar code.
Because two-dimensional bar code will be printed on the business card, for attractive in appearance, require the two-dimensional bar code area as far as possible little, but too little resolution can not reach the requirement of recognition device again, so can not light dwindle the area of two-dimensional bar code, must guarantee the resolution of bar code simultaneously.
In order to allow two-dimensional bar code area minimum under the prerequisite that guarantees resolution, just require the business card content of two-dimensional bar code carrying the least possible.If it is minimum that the business card content is woven together certain content entirely, but has lost attribute information, can't efficiently handle.So just need to adopt method of the present invention, make these three requirements reach best balance.
By the content on the business card is analyzed discovery, have category attribute and sequential attribute in these, as business card 1 is name, position, Business Name, CompanyAddress, postcode, phone, fax, mobile phone, E-mail, company's network address arrangement, clauses and subclauses have to have more to be lacked, what have has a plurality of CompanyAddresses etc., order also differs, and for loyalty embodies incidence relation between former business card style and the content, these attribute informations on the business card all need to keep.
So earlier with the information segmenting on the business card, again these information segments are classified, as name, degree, academic title, Business Name, CompanyAddress, postcode, phone, fax, mobile phone, E-mail, network address etc., then these classifications are numbered as following table 3:
