Embodiment
The method the present invention relates to is aimed at the unified identification code of in Internet of Things, product being carried out, and utilize method of the present invention to unify to this process that identification code is resolved, before resolving is described, for convenient, understand, the present invention unifies identification code to Internet of Things and does to explain.
There is the Internet of Things encoding scheme of various criterion in existing Internet of Things, have the coding of different systems for the product of different systems, unified Internet of Things code identification system is not yet set up, every country and international organization are all at the coding of attempting proposing to be suitable for the Internet of Things application, for example: EPC, Ucode, object identity (Object Identifier, hereinafter to be referred as OID), Digital Object Unique Identifier (Digital Object Unique Identifier, hereinafter to be referred as DOI) etc.
EPC is based on radio-frequency (RF) identification (Radio Frequency Identification, hereinafter to be referred as RFID) and the unique coding in the whole world that each entity object is distributed of Internet, can realize each single product is encoded, mainly apply in the logistics supply chain field at present, Ucode is only identifier (the Unique Identifier that Japan proposes, hereinafter to be referred as UID) coding that adopts of system, mainly physical entity and position are encoded, but UID system and international standard are also incompatible, its coding standard, air-interface standard etc. are all the standards of Japan this country, do not obtain the approval of International Standards Organization, OID is (the International Organization for Standardization of International Standards Organization, hereinafter to be referred as ISO)/(the International Electrotechnical Commission of International Electrotechnical Commission, hereinafter to be referred as IEC) 8824 and the ISO/IEC9834 series standard in a kind of Indicator system of defining, the original intention of its formulation is realization unique identification to " object " in Open System Interconnection, the object here can be any physics, virtual, the thing of information, it is the part of the whole system of Open System Interconnection, but due to too flexibility of OID, many yards of one things easily appear, be not easy to unified management, and the OID opening also needs to strengthen in fail safe.
Therefore, incompatible in view of between the coding scheme of above-mentioned different coding standard, and along with the Internet of Things application deepens continuously, collaborative and information sharing meeting between information interaction between cross-system, cross-platform, cross-region, heterogeneous system progressively increases, and makes to set up unified Internet of Things code identification system and become common recognition.At home in the application of Internet of Things demonstration project, adopt the encoding scheme of system separately, when needs are realized interconnecting of cross-system, cross-platform, cross-region, tend to run into various bottlenecks, so national Internet of Things basic standard working group-identification technology project team makes overall planning from State-level, the comprehensive coordinate formulation meets China and applies actual standard, really, on existing various application systems basis, proposes to have compatible solution; Can allow existing various coded systems continue to play a role, can take into full account new application demand again, formulate unified code identification system, set up on this basis national Internet of Things and unify the identity management public service platform, for the construction of all trades and professions Internet of Things provides support, the Internet of Things in the present invention is unified identification code Ecode.This Ecode has uniqueness to entity coding, and this uniqueness can be both that the overall situation is unique, can be also local unique; And there is good compatibility, and can realize the compatibility to already present encoding scheme in existing each application, by setting up various mapping rulers and coding mapping relations, support the various codings that existed.
The coding structure of Ecode is " version information (Version; hereinafter to be referred as V)+code identification system sign (Numbering System Identifier; hereinafter to be referred as NSI)+body code (Main Code; hereinafter to be referred as MD) ", fundamental length is 96bits, 128bits, 256bits etc., according to selecting different versions, length difference, when version is flexible expansion as required, concrete scheme is in Table 1; And Ecode may reside in the carrier of the types such as one dimension code (code128 coding), Quick Response Code and RFID label (ISO/IEC18000-63, ISO/IEC18000-3m3).
Wherein, the version information in table 1 is for distinguishing the Ecode of different pieces of information structure.Version information length is 4bits.Can adopt decimal representation (version 1010
2～1111
2forbidding); This version information is distributed unitedly by China Internet of Things Unified coding management organization.When adopting version 0, its code only can adopt the RFID tag identifier; When adopting version, be 0001
2the time, the length of Ecode is 96bits, except adopting one dimension code, Quick Response Code sign, can also adopt RFID tag identifier (the unique identification section length of main flow RFID label is 96bits at present); When adopting version, be 0010
2the time, the length of Ecode is 128bits; When adopting version, be " 0011
2" time, the length of Ecode is 256bits; When adopting version, be 0100
2the time, the NSI length of Ecode is 16bits, the length of Ecode is determined by length indicator.
Table 1
NSI in table 1 is used to indicate the body code of a certain coding scheme, difference according to version information, NSI length can be 8bits, 12bits, 16bits etc., and NSI is by the unified distribution of China Internet of Things Unified coding management organization, and different NSI represents different coding schemes; It should be noted that, when the body code of a certain coding scheme will become Ecode, will unify identification code management organization online application version information and NSI to China's Internet of Things, and the length of body code and data structure are determined by NSI, and the data structure of body code and distribute the management organization by a certain coding scheme to administer and maintain voluntarily, when the body code data structure that the management organization of a certain coding scheme formulates should be put on record to management China Internet of Things Unified coding management organization.At this, contact between version information, NSI and body code is described for example, take version 1 as example, specific as follows:
When Ecode adopts version 1, its corresponding NSI length is 12bits, total length is that 12bits is current, the data structure of having distributed is as shown in table 2, wherein, GTIN in table 2 is project trade code (Global Trade Identification Number, hereinafter to be referred as GTIN), GLN is participant position code (Global Location Number, hereinafter to be referred as GLN), SSCC is Logistic Unit code (Serial Shipping Container Code, hereinafter to be referred as SSCC), GRAI is global Returnable Asset code (Global Returnable Asset Identifier, hereinafter to be referred as GRAI)), GIAI is global single coding of assets (Global Individual Asset Identifier, hereinafter to be referred as GIAI), GSRN is GSRN (Global Service Relation Number, hereinafter to be referred as GSRN), version 1 can be for the coding compatibility with the bar code system, can also be to international telephone number (Telephone Number Mapping working group, hereinafter to be referred as ENUM) carry out compatibility, also can carry out compatibility etc. with the sensor node identify label, be below the introduction of Ecode to the compatibility of some coding schemes while adopting version 1:
(1) Ecode is for the compatibility of the commodity code based on bar code
Table 2
Commodity code based on bar code comprises authentication code and the adeditive attribute code of trade account code, Logistic Unit code, global Returnable Asset code, participant position code and service relation code etc., wherein, GTIN is most widely used authentication code in current commodity code system, the GTIN coding structure is as shown in table 3, Logistic Unit identifies by SSCC, and SSCC is 18 digit numerical code without implication, fixed length, does not comprise classified information.The coding structure of SSCC is as shown in table 4.
Table 3
Table 4
When adopting Ecode to carry out compatibility to the commodity code based on bar code, the NSI that is distributed to this system by Internet of Things Unified coding management organization is: 003
h-008
h, according to length and the character types of body code, the version of GTIN and SSCC is all selected version 1, and its data structure is distinguished with NSI, as shown in table 5:
Above-mentioned table 2 that is to say, Ecode is for the compatibility of the coding of commodity code system, that the structure of passing through distributed version information+NSI+ body code realizes, because under a version, a plurality of NSI are arranged, the body code that different NSI is corresponding different, so not only can distinguish body code, also for the parsing body code of back, make place mat.
It should be noted that, the coding of all the other versions of Ecode under also can compatible other systems, for example version 1 can be realized the compatibility to electronic supervision code, version 3 can be realized the compatibility to the handle code, edition 4 is realized the compatibility to national OID code, at this, just differs and one has given an example.
On the other hand, for the coding of current object, the dissimilar codings such as binary system, decimal number font, alphanumeric (character type) are arranged, the idiographic flow that is converted to Ecode is also done here with brief description:
1) binary system: binary system need not transform, and can directly be written as " V+NSI+ binary coding ";
2) decimal system: body code directly changes into 1 decimal system according to 4 binary systems and carries out decoding, and adopting version is 1, finally is encoded to: NSI+4 position, V+NSI(1 position NSI)+numeral
For example: body code is 123456. version V1, and NSI is the 000000001000(decimal system 8).
Suppose to adopt bar code, corresponding Ecode is encoded to: 10008123456; Coded data is: " Ecode=10008123456 ";
Suppose to adopt Quick Response Code, corresponding Ecode is encoded to " Ecode=10008123456 ";
3) alphanumeric: body code adopts 1 character of 6 binary representations, as shown in table 5:
Table 5
For example: be encoded to A123456, version is that 3, NSI is the 0000000000001000(decimal system 8), suppose to adopt bar code, corresponding Ecode is encoded to: 30008A123456; Coded data is: " Ecode=30008A123456 " (annotating: do not recommend alphanumeric to adopt bar code mark, recommend preferential Quick Response Code or the RFID label of adopting to mean);
Suppose to adopt Quick Response Code, corresponding Ecode is encoded to: 30008A123456; Coded data is " Ecode=30008A123456 ";
Suppose to adopt the RFID label, when adopting segmentation label memory sign, first set the indicating bit in application type sign (Application Family Identifier, hereinafter to be referred as AFI) district, corresponding Ecode is encoded to: "
00110000000000001000001010000001000010000011000100 000101000110. ".
General, the storage of Ecode or the form of obtaining Ecode can have following several, according to the practical application difference, its corresponding identification means are arranged:
The first: to brand-new sector application, also there is no unified SIC code system, if adopt the coding structure of Ecode, therefore " VNSI+ body code " can be done in as a whole data writing carrier, while obtaining the information of VNSI, can be obtained by this data medium (this data medium can be bar code, Quick Response Code or RFID etc.).
If adopt bar code as carrier, can adopt at present general Code128 bar code as carrier, for fear of with existing coded system conflict, " Ecode=version+NSI+ body code " integral body is write in bar code, and wherein " Ecode=" is as an identifier that adopts the Ecode coding scheme.
If adopt Quick Response Code as carrier, by formulating the Internet of Things Unified coding pattern of Quick Response Code, thereby " version+NSI+ body code " integral body is write in Quick Response Code, wherein " Ecode=" is as an identifier that adopts the Ecode coding scheme.
If while adopting RFID as carrier, according to the difference of label air protocol and tag storage structure, need to do concrete regulation, Ecode is when carrying out the radio-frequency (RF) tag carrying, be with binary storage in the internal memory of radio-frequency (RF) tag, at present the storage organization of radio-frequency (RF) tag mainly contains three kinds:
(1) segmentation internal storage structure: four area stores of dividing according to logical memory, the performance data that each area stores is corresponding, the more convenient recognizer reading out data of this mode, improve the operating efficiency of recognition process, the radio-frequency (RF) tag internal storage structure of ISO/IEC18000-3 pattern (Mode) 3 and ISO/IEC18000-6 type (Type) C air interface protocol for example, its internal storage structure, from being divided in logic four sections internal memories, as table 6 to as shown in table 9:
Table 6
Table 7
Table 8
Table 9
Ecode should be stored in and be designated application heap 01(unique identification district, also referred to as the UII district) the position that starts of 17h; The data storage of application heap 01, except the regulation here, all the other are carried out in accordance with corresponding air interface protocol regulation; According to the Ecode application class, when the Ecode of storage coding belongs to version 0, the agreement controlled area 17hbit of application heap 01 sets to 0; When the Ecode of storage encodes other versions constantly, the agreement controlled area 17hbit of application heap 01 puts 1.
For example: for the application of a certain field, be encoded to " ABCD12345678 ", AFI value (00001010)
h, the NSI of this coding is (0000000000001001)
2; Suppose an Ecode for RFID is used to ISO/IEC18000-6Type C label, the Ecode value is as follows: (for ease of meaning, adopting hexadecimal)
| Ecode | V | NSI | Body code |
| Value | 3 H | 0009 H | (ABCD12345678) H |
(2) discrete internal storage structure: the memory location of coding is controlled addressing and is write by the Based Intelligent Control element of label and read, for example the radio-frequency (RF) tag internal storage structure of ISO/IEC18000-3Mode1 and ISO/IEC18000-6TypeA air interface protocol; Discrete label memory is that physical memory is mapped to the different region of memory in address, can carry out independent addressing by corresponding order, to discrete label memory, during the writing and read of data, by the corresponding command, realize, AFI and Ecode are stored in respectively on two sections continuous memory storage units, and the Ecode of version 0 only is stored in the segmentation label memory, therefore just do not consider here, only stipulate the storage of version 0 other versions Ecode in addition, be specially:
When the coding of storage belongs to the Ecode of non-zero version, whole coding structure is stored in AFI zone and the article unique identification district (UII) of internal memory, and the data storage beyond coding is carried out in accordance with corresponding air interface protocol regulation, specifically as shown in table 10:
Table 10
(3) contiguous memory structure: all data are according to address height sequential storage successively, the radio-frequency (RF) tag internal storage structure of ISO/IEC18000-4Mode1 and ISO/IEC18000-6TypeB air interface protocol for example, the label of following ISO/IEC18000-4Mode1 and ISO/IEC18000-6TypeB air interface protocol belongs to the label of linear internal memory, this linearity label memory refers to that the physical memory of label is mapped to one section continuous memory field, its logical memory structure is as shown in table 11, wherein, Byte12 stores 0Ah, means to defer to afore mentioned rules:
Table 11
Generally speaking, Ecode should leave the article unique identification district of radio-frequency (RF) tag in, and the article unique identification district of radio-frequency (RF) tag, according to different tag types and difference; For the situation of a plurality of Ecode codes of storage in a radio-frequency (RF) tag, the article unique identification district that foregoing is defined in radio-frequency (RF) tag should only store an Ecode, and remaining Ecode is stored in non-article unique identification district.
The second: for the coded system (i.e. the system of existing already present coding scheme) of some existing ripe application, what in the carrier of existing article, carry is SIC code, can't carry " V+NSI " these information, can by the Ecode label by " V+NSI " information labeling in label, Ecode label and the sector encode (bar code information, 2 D code information, RFID label information etc.) jointly formed Ecode.
The third: also some situation is that the sector application coding is binding with specific carrier, this situation, server identifies this coding according to the data medium identifier and comes from which kind of coded system, thereby obtain NSI and the version information of this system, can regard that VNSI is stored in the lane database in this cover system as; And the data medium identifier is comprised of identifier, bearer type sign, carrier subclass sign, and the structural representation of this data medium identifier is as follows: "] cm " wherein, "] " identifier; " c " bearer type sign; " m " carrier subclass sign.
Run through label information at recognizer, during to application system transmission data, the data medium identifier is loaded before transmission information by recognizer; Application system is according to identifier "] " determine whether to have used the data medium identifier, and determine according to this data medium identifier the coding that the data that exist in this carrier are a certain application system, thus determine " V+NSI " of this coded system.For example, for bar code, after recognizer completes recognition bar code " 6901234567892 ", increase code system identifier "] E6901234567892 " after be transferred to application system, receive "] E16901234567892 in application system " after message, according to the Internet of Things coding criterion, and judge that according to " E " this section code belongs to the bar code coding, therefore, its " VNSI " is 10003, it is converted into to unified Ecode and is encoded to: 100036901234567892.
The 4th kind: for specific sector application, sector application should belong to management organization's registration the V+NSI information of the sector coded system, after its data medium adopted is determined, can formulate standardized data protocol, by the V+NSI message identification in specific agreement controlled area, during recognition, as long as follow this data protocol, can obtain " V+NSI " information of this coded system, determine it is the coding of which system by the content that reads the agreement controlled area, then determine that according to this data protocol its NSI(data protocol writes in recognizer, this agreement has been stipulated the mapping relations of coded system and VNSI).
The 5th kind: if sign " V+NSI " information that all can't be direct or indirect with upper type, only has so the mode by middleware, when obtaining body code information, obtain the information of V+NSI, and when body code is transmitted, add V+NSI information, form Ecode, be about to non-Ecode and be converted to Ecode.
Above-mentioned described part is the integral body introduction for Ecode, and for the process of the parsing of above-mentioned Ecode, referring to Fig. 1, concrete method is as follows:
S101: Ecode is resolved, obtain version information and the NSI of Ecode.
Concrete, the recipient is scanned the Ecode on the article in Internet of Things, and this Ecode is sent to server, this server can be sign cloud platform, inside is provided with middleware, and the process software that this middleware is server end, for the treatment of the sequence of operations of server.
Server is after the Ecode that receives recipient's transmission, and the NSI database of querying server end, with version information and the NSI that obtains Ecode.
S102: according to above-mentioned version information and NSI, obtain the domain name transformation rule regular expression of Ecode body code.
S103: according to the domain name transformation rule regular expression of body code, the URI address that obtains resolution server corresponding to this body code.
Concrete, server carries out domain name processing according to CN domain name transformation rule by NSI by obtained NSI, and according to the NSI of this Domain Name Form registering sites, go to search in the encoded data structure database of server end, to obtain the domain name transformation rule regular expression of Ecode body code, the domain name handling process of NSI is as follows: according to the hierarchy of NSI, by at different levels convert ten's digit to after, and by its inversion, finally mend suffix " nsiroot.cn ", for example: the decimal system form of main body of articles code is: 6901234567892, the VNSI that this coding standard is corresponding is: 1.0003, the CN Domain Name Form registering sites of this NSI is so: 3.1.snsroot.cn.
S104: send the URI address, so that recipient's resolution server corresponding according to Xiang GaiURI address, above-mentioned URI address sends the analysis request of aforementioned body code.
Server is according to the domain name transformation rule regular expression of obtained Ecode body code, the Ecode body code is carried out to the domain name processing, and search the information server address base according to the body code of Domain Name Form registering sites, to obtain the URI address of resolution server corresponding to this body code; And this URI address is sent to the recipient, make the recipient according to this resolution server corresponding to this URI address of URI address search; And send the analysis request of aforementioned body code to this resolution server.This resolution server, after the analysis request that receives the aforementioned body code that the recipient sends, is processed this analysis request according to existing analytic method, to obtain the decoded information of this body code, i.e. and the relevant information of article.That is to say, above-mentioned process is that server knows according to the NSI in Ecode the coding scheme that this Ecode body code is concrete in which, then NSI is processed to obtain the Domain Name Form registering sites transformation rule (being the data structure of body code) of Ecode body code, and then the URI address that obtains the resolution server in this Ecode body code place system, send to resolution server corresponding to this URI address to be resolved the analysis request of body code.
Because above-mentioned Ecode all can carry out compatibility to the coding of each coding scheme, as long as just can know it is the coding of which coding scheme according to the version information in Ecode and NSI, then the analysis request of Ecode body code is pointed to the resolver of concrete coding scheme according to the NSI after processing, no matter be the coding of which coding scheme, method of the present invention all can realize the parsing to the coding under each coding scheme.
