Abstract
The present invention provides a bar code coding method capable of implementing that several bar code standards can be mixed in a group of bar codes to represent several character symbols. Said invention uses bar code identifier with specific purpose as different bar code standard and identification of different language character symbol. Said bar code identifier can be used for identifying bar code standard, language character symbol type, bar code character string length and/or bar code character positioning information.
Description
Technical field
The present invention relates to the bar code field, particularly a kind of barcode encoding method.
Background technology
Along with fast development of computer technology, and the widespread use of barcode technology, a large amount of information all uses bar code to work out, as various personal information, product information, publication information etc.
According to existing barcode technology, all bar code standards all can not other spoken and written languages of direct representation for example Chinese, Japanese, German, roman character etc.The standard character collection of most of bar code standards itself only comprises numeral, only has minority can comprise English alphabet and numeral, for example 39 yards and 128 yards.The information that existing bar code is expressed is directly perceived inadequately, and the user can't directly understand, and has limited the range of application and the function of barcode technology greatly.
Now occurred with certain spoken and written languages for example Chinese character information weave into the method for bar code, it is one group of character or numeral that Chinese character is compiled by encode Chinese characters for computer standard (for example the standard of GB, the four-corner system or oneself definition etc.).This group character or numeral are taken from the standard character collection of certain bar code standard, should organize character or numeral again and be bar code by bar code standard volume, Chinese character information can be stored in the bar code.Use with it that corresponding decoding method can be visual and understandable spoken and written languages with bar code decoding, greatly the application function of spreading bar-code and range of application.But this method only can be represented a kind of spoken and written languages in one group of bar code, if mix multilingual literal and numeric character in the passage, then can't adopt above-mentioned coding-decoding method.
Addressed the above problem two kinds of approach: first kind of approach is that corresponding every kind of spoken and written languages redefine a kind of bar code standard, makes its bar code character corresponding one by one with symbols such as spoken and written languages, English alphabet, numerals; Second approach is on the basis of existing bar code standard it to be carried out secondary coding.Comparatively speaking, first kind of approach is less feasible, is example with the Chinese character, and Chinese characters in common use just have more than 3,000, and the workload that defines the bar code character of this quantity and unique identification character is too big.
Summary of the invention
Can't in one group of bar code, represent the problem of multilingual literal to the object of the present invention is to provide a kind of barcode encoding method in view of prior art, can multilingual literal, numeral and encoding symbols be enrolled its mixing in one group of bar code.
For realizing purpose of the present invention, a kind of barcode encoding method is proposed, to the kinds of words encoding symbols, use the bar code mark symbol that has certain sense.
Above-mentioned bar code mark symbol is used to identify bar code standard, spoken and written languages sign pattern, bar code character string length and/or bar code character locating information.Bar code bar code mark symbol can identify the spoken and written languages sign pattern that certain bar code mark accords with the string segments between another bar code mark symbol between dissimilar spoken and written languages symbols.Described bar code mark symbol can also be emitted on an end of bar code successively, corresponds respectively to the discharging order of the character string of bar code mark symbol according to the bar code mark symbol, is emitted on the other end of bar code successively.
Bar code mark symbol provided by the invention, special character, reserved characters or the character that is of little use that its value can utilize the bar code standard character to concentrate accord with as bar code mark, perhaps define the bar code standard character and concentrate the special character that does not have to accord with as bar code mark.
The inventive method can be provided with a bar code mark symbol to the standard character of bar code, character to non-bar code standard is provided with at least one bar code mark symbol in addition, perhaps the spoken and written languages symbol is defined a bar code mark symbol respectively, no matter and whether this spoken and written languages symbol is the bar code standard character.First group of character string can presetting bar code is the spoken and written languages symbol of certain particular type, omits when coding bar code mark symbol that should the section character string.The bar code mark symbol comprises two eigenwerts, an eigenwert identification character type; Another eigenwert sign is to the length of character string that should the bar code mark symbol.The value of described bar code mark symbol can also be made of jointly block information, the bar code mark symbol corresponding characters string length of spoken and written languages symbol.
Barcode encoding method of the present invention can be implemented in mixes multiple bar code standard in one group of bar code, expression multilingual letter symbol, this group bar code can be fixed length or random length, bar code can be worked out voluntarily by the user, can encrypt bar code information, can realize efficiently, express the meaning flexibly with bar code.
The present invention can be widely used in the bar code of certificate, business card, kinds of goods, books, bill etc., and user-defined multilingual character and numerical information volume are bar code; Can be applicable to business automation system, warehousing management, traffic administration, financial file management, business documentation management, medical control, person identification and various sorting techniques aspect, be penetrated into the every field of computer management and daily life.

Embodiment
Below with reference to accompanying drawings and in conjunction with specific embodiments, realization, functional characteristics and the advantage to the object of the invention is described further.
According to first embodiment of the invention, a kind of barcode encoding method is proposed.Present embodiment can be by using one or more bar code mark symbols, spoken and written languages symbols different in one group of bar code is separated, bar code mark symbol is placed on before the field of corresponding language letter symbol, expression accords with the spoken and written languages sign pattern of character string before to next bar code mark after this bar code mark symbol, be implemented in one group of bar code with this and express the multilingual letter symbol simultaneously.
According to the actual bar code standard difference of selecting for use, the definition of bar code mark symbol has two kinds of methods: so first kind of bar code standard less to some " standard character collection ", itself can't represent more character, whether tackle every kind of character, symbol this moment and define bar code mark symbol respectively, be " standard character " of this bar code and do not distinguish character.
The Biquinary Code of for example reporting to the leadship after accomplishing a task, its standard character only has 10 numerals such as 0～9 grade, needs to define bar code mark respectively to multiple characters such as numeral, English, Chinese, punctuates respectively this moment and accords with.
Another kind is that bar code standard self " standard character collection " is bigger, can represent more character, need not carry out extra coding.Can treat with a certain discrimination standard/non-standard character this, a bar code mark symbol sign all " standard characters " only is set, and accord with the character that identifies respectively in non-" standard character collection " such as Chinese, German, Japaneses with other bar code marks.
With 128 bar code standards is example: the initial symbol of standard definition has three kinds of StartA, StartB, StartC, respectively corresponding three kinds of character set.Utilize three kinds of character set can represent the alphabet that ascii character-set and expansion ascii character are concentrated altogether.
" standard character collection " is bigger owing to being somebody's turn to do, can represent multiple English, numeral and punctuation character, only need " standard character " bar code mark symbol of definition, sign all " standard characters ", the bar code mark symbol that defines various " non-standard characters " more respectively gets final product.
According to the difference of bar code standard, the value of bar code mark symbol also can adopt dual mode: first kind is to utilize special character, the reserved characters in the bar code " standard character collection " or the character that is of little use uses as the bar code mark symbol.The advantage of this mode is not need self-defined bar code mark symbol and meet the bar code standard; But shortcoming be if the expression information in contain these special characters or the character that is of little use, then may cause the confusion of Code And Decode.
The second way is according to the bar code standard, the special character that does not have in more self-defined " standard character collection ".The advantage of this mode is that span is bigger, and is more flexible, and shortcoming is that special character does not have ASCII character, and part bar code standard is not supported the definition of multiple special character.
The value and the define method of above-mentioned bar code mark symbol need be used in combination according to concrete bar code standard.For example, use " standard character " of 128 yards standards: "+", "-", "/", " # ", " % ", “ ﹠amp; ", " * " as the value of bar code mark symbol, one of them value sign " standard character ", all the other a plurality of values identify " non-standard characters " such as Chinese, Japanese, Korean, German, French, Greece and roman characters respectively, referring to Fig. 1; Also can not distinguish standard/non-standard character, each value identifies English, numeral, punctuation mark, Chinese, Japanese, Korean, German respectively.
And for example, adopt three nine-day periods after the winter solstice during the sign indicating number standard, can self-defined a plurality of special characters as the value of bar code mark symbol, the corresponding bar code mark symbol of each special character.The bar code mark symbol can be distinguished bar code " standard character " and other all kinds of non-standard characters, referring to Fig. 2; Also can not distinguish standard/non-standard character.
Below illustrate the method that adopts present embodiment, utilize the bar code mark symbol to realize mixing in one group of bar code specific coding, the decoding process of multilingual letter symbol.The coding flow process as shown in Figure 3:
The 301st step, read first character in the character string, obtain its type and be Chinese, before this character, add corresponding bar code mark symbol;
In the 302nd step, defining variable i is since 2 countings.Obtain the type of i character, and it is adopted corresponding coded system coding, the bar code character that obtains with coding replaces original character;
In the 303rd step, relatively whether the type of i character is identical with last character types; If two character types are identical, then I added for 1 (the 304th step);
The 304th ' step, if two character types differences, the bar code mark that inserts the bar code character form of respective type before this i character accords with;
The 305th step judged whether that coding do not finished in character in addition, and whether character string finishes, if also have character, then returned and carried out for the 302nd step, and circulation is encoded to all characters in the character string successively;
The 306th step if do not finish the character of coding, then finished cataloged procedure, the bar code character that output encoder obtains, and the coding flow process finishes.
For describing flow process in detail, this sentences character string " Chinese china2004 " is example, adopts 128 bar code standards and Chinese character national standard to encode.Adopt "+", " * " symbol in " standard character collection " to accord with, respectively sign Chinese and " standard character " as bar code mark.
According to the coding flow process, at first read first character in the character string " in ", obtaining type is Chinese.Then character " in " bar code mark of preceding insertion bar code form symbol "+"; Next to character " in " coding, earlier according to national standard, with Chinese character " in " be converted to four figures word string " 5448 "; Use 128 bar code standards that numeric string " 5448 " is compiled again and be bar code.
Obtain the 2nd character " state ", be converted into four figures word string " 2590 "; Use 128 bar code standards that numeric string " 2590 " is compiled again and be bar code.
Relatively " state " and last character " in " character types, type is identical then carried out for the 304th step, i becomes 3.
Because character string still is untreated and finishes, returned for the 302nd step, obtain the type of the 3rd character " C ".Because English character is 128 bar code standards " standard character ", be bar code so it is directly compiled according to 128 standards.
The 303rd goes on foot, and compares the type of " C " and last character " state ", and the type difference then carries out the 304th ' step, at the bar code mark symbol " * " of the preceding insertion bar code form of character " C ", i becomes 4.
Because character string is not over yet, returned for the 302nd step once more and encode, so until end of string, all characters are all compiled is bar code.This moment output encoder result such as Fig. 5, cataloged procedure finishes.
According to another embodiment of the present invention, a kind of barcode encoding method is proposed.Present embodiment is represented the number of bar code mark symbol with first character of bar code, the number of character string just, the bar code mark symbol is emitted on the leading portion of the whole bar code after first character successively, do not have at interval between the character string corresponding to each bar code mark symbol of front end, character string is emitted on the back segment of bar code successively according to the discharging order of bar code mark symbol.
According to the actual conditions differences such as length of bar code standard, character types, character string, provide two kinds of bar code organization schemes:
First kind is that bar code mark symbol comprises two eigenwerts, first eigenwert identification character type, as " in ", " moral ", " method " etc.; Second eigenwert sign is to the length of character string that should the bar code mark symbol; After reading bar code mark symbol,, according to second eigenwert length of this section character string as can be known, separate again with this character string with other character types according to the character types of first eigenwert type of corresponding character string as can be known.
With last embodiment similarly be, according to the actual bar code standard difference of selecting for use, the definition of this programme bar code mark symbol also can have two kinds of methods: so first kind of bar code standard less to some " standard character collection ", itself can't represent more character, whether tackle every kind of character, symbol this moment and define bar code mark symbol respectively, be " standard character " of this bar code and do not distinguish character.Another kind is that bar code standard self " standard character collection " is bigger, can represent more character, need not carry out extra coding.Can treat with a certain discrimination standard/non-standard character this, a bar code mark symbol sign all " standard characters " only is set, and accord with the character that identifies respectively in non-" standard character collection " such as Chinese, German, Japaneses with other bar code marks.
And according to the difference of bar code standard, the value of bar code mark symbol also can adopt dual mode: first kind is to utilize special character, the reserved characters in the bar code " standard character collection " or the character that is of little use uses as the bar code mark symbol.The second way is according to the bar code standard, the special character that does not have in more self-defined " standard character collection ".The value and the define method of above-mentioned bar code mark symbol need be used in combination according to concrete bar code standard.
Be example still, and for convenience of description, still adopt 128 bar code standards herein with character string " Chinese china2004 ".The bar code mark symbol is selected for use "+" and " * " to identify " Chinese " respectively and is reached " standard character ", and the character string of compiling out with above-mentioned bar code method for organizing is " 2+* China china2004 "; If bar code mark symbol is used "+", " # " instead and reach that " * " identifies " Chinese " respectively, " English " reaches " numeral ", the character string of compiling out with above-mentioned bar code method for organizing is " the Chinese china2004 of 2+#* ".
Similar according to flow process and last embodiment that this bar code method for organizing is encoded, so do not give unnecessary details.
Second kind of bar code organization scheme is that the value that bar code mark accords with is made of jointly block information and this bar code mark symbol corresponding characters string length of spoken and written languages symbol.Be length of interval of every kind of spoken and written languages sign convention in advance, for example stipulating that English word string is the longest has 50 characters, and Chinese is the longest 20 characters, and numeric string is the longest 30 characters is arranged; With this partition length interval, English is (0～49), and Chinese is (50～69), and numeral is (70～99).The physical length of every kind of spoken and written languages symbol string should be 0 between the length of corresponding types.The value of this length of interval and order can be adjusted.
When forming the bar code mark symbol, the initial value and the physical length addition of this kind spoken and written languages sign character string with the length of interval of certain spoken and written languages symbol draw the value that bar code mark accords with.Be defined as example with above-mentioned length of interval, if English character string physical length is 5, the value of then English bar code mark symbol is 0+5=5; If Chinese character string physical length is 7, the value of then Chinese bar code mark symbol is 51+7=58; If the digit strings physical length is 2, the value of then digital bar code mark symbol is 71+2=73; If also have the Chinese character string, physical length is 20, and then corresponding bar code mark symbol value is 51+20=71.
With character string " Zhang San 13570234025 " is example, adopts above-mentioned length of interval define method, adopts 128 yards standard codes, and the bar code mark symbol is respectively 50+2=52, represents 2 Chinese characters; 70+11=81 represents 11 bit digital; The coding result character string is " 52815337409313570234025 ", and corresponding bar code as shown in Figure 6.
Certainly, described bar code mark symbol also can be distinguished standard/non-standard character, all " standard characters " is provided with a character length interval, and other various non-standard characters are defined a length of interval respectively.
When encoding with this bar code organizational form, with the standard (such as GB, the four-corner system or the own standard that defines etc.) of agreement the character that bar code can direct representation weaved in multilingual literal such as Chinese character, English character, calculate their bar code mark symbol then according to the length of each character string respectively, their bar code mark symbol is being placed on the front of all fields in proper order by this according to putting in order of dissimilar fields.Idiographic flow as shown in Figure 4.
In invention, first group of character string can presetting bar code is the spoken and written languages symbol of certain particular type, can omit when coding bar code mark symbol that should the section character string.For example, default first group of character string is Chinese character, then just can omit going here and there the bar code mark symbol of character string.When the bar code of having omitted first bar code mark symbol with this kind method is decoded, need to adopt corresponding coding/decoding method to decode according to first group of default character string type.
According to above-mentioned two embodiment, provide the coding method of adopting bar code mark symbol hybrid representation multilingual literal in one group of bar code.The method according to this invention also can be mixed multiple bar code standard in one group of bar code, to improve code efficiency and to reduce bar code length.The principle of this method is that several character fields are formed a whole group bar code, and each section represented with the bar code of various criterion, separates with a barcode types identifier between section and the section.
Realize multiple bar code standard, the multilingual letter symbol is carried out Methods for Coding is: earlier with various spoken and written languages corresponding codes methods, for example the Chinese characters of the national standard coding is once encoded to information, the coding result segmentation and specify every section to use which kind of bar code standards, then each section encoded with corresponding bar code standards, at last the coding result of each section (bar code) is made up by original series arrangement, and insert corresponding barcode types identifier.
It will be understood by those skilled in the art that the order that character reads, character combination mode, coding can suitably be adjusted opportunity in the flow process of encoding in the foregoing description.As long as carry out the separation and the differentiation of character string, and, can realize that the above-mentioned change of method of barcode encoding of the present invention does not exceed the scope of protection of the invention by bar code mark symbol identification character string type according to the bar code mark symbol; And bar code standard, multilingual literal code standard etc. also can be selected flexibly according to prior art.The various remodeling to technical solution of the present invention that do not depart from inventive concept will fall into claim of the present invention institute restricted portion.
