Embodiment

For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.

The flow chart of the Internet of Things resource information acquisition methods that Fig. 1 provides for one embodiment of the invention.As shown in Figure 1, the method for present embodiment comprises:

Step 101, terminal equipment obtain the standard sign and the resource identification of Internet of Things resource; Said resource identification is used for unique identification Internet of Things resource, and said standard sign is used to define the naming rule of resource identification.

The terminal equipment of present embodiment can be a various Internet of Things application terminal equipment, as through the user terminal (for example smart mobile phone) of Web service visit Internet of Things resource, directly the intelligent gateway of Internet of Things resource etc. is controlled in management.

The Internet of Things resource of present embodiment can be the physical resource in the Internet of things system, and for example wireless sensor node, radio frequency electronic tag etc. also can be the logical resource in the Internet of things system, for example text, audio frequency, video etc.

In the present embodiment, Internet of Things resource use standard simultaneously sign and resource identification identify.Wherein, the standard of Internet of Things resource sign and resource identification are stored in the Internet of Things resource usually.Terminal equipment can directly obtain the standard sign and the resource identification of this Internet of Things resource from the Internet of Things resource.For example, if the Internet of Things resource is a wireless sensor node, then terminal equipment can obtain the standard sign and the resource identification of wireless sensor node through carrying out information interaction with wireless sensor node.Again for example; If the Internet of Things resource is a logical resource; Then the standard of this logical resource sign and resource identification can be carried at as the part of this logical resource in this logical resource, and based on this, terminal equipment can directly obtain its standard sign and resource identification from logical resource.

Wherein, said various sign is exactly a kind of name symbol that is used to discern different objects.The resource identification of Internet of Things resource (Resource Identifier; RID) be mainly used in unique identification Internet of Things resource; And the standard of Internet of Things resource sign (Standard Identifier SID) is mainly used in the naming rule of the resource identification of definition Internet of Things resource.

Traditional unified resource identifier (Uniform Resource Identifier; URI) only be used for recognition network (Web) resource; For example the basic format of URI is: < URI >: :=< scheme >: < scheme-specific-part >; Form by the title (i.e. < scheme>part) of name outline and the unique identifier (i.e. < scheme-specific-part>part) that adopts this name outline to generate, separate with ": " between title and the identifier.

< scheme-specific-part>part in the basic format of URI is formed i.e. < scheme-specific-part>by 4 parts usually: :=< authority>[< path >] [< query >] [# < fragment >].

Wherein, authority is the Institution Code that adopts this name outline, the i.e. host name of deposit networked resources.Path is the relative path information of deposit networked resources, with "/" as at interval.Query is by " attribute-value " expression formula for search to forming, with "? " Beginning.Fragment is the child resource of sign with respect to primary resource, starts with " # ".

Wherein authority is essential attribute, and path and query, fragment are optional attributes.

Optional, the standard sign and the resource identification of present embodiment all can be realized through the URI of expansion.

Optional, the structure of the URI of a kind of expansion that present embodiment provides mainly is that original Hostname < authority>is expanded to resource name < resource >.Optional, the resource name of present embodiment < resource>can belong to three parts by resource identification, resource type, resource again and form.

Wherein, when the URI of expansion was used for resource identification, the implication of each daughter element was following:

Resource identification: be used for distinguishing different Internet of Things resources, can come the marker networked resources according to local nomenclature principle by each heterogeneous network manager in the Internet of Things subdomain in this locality.Said this locality can be the resource identification management system of management resource sign, but is not limited thereto.

Resource type: the existence form that is used for describing the Internet of Things resource.For example, can be the description of classification, for example, the type of the Internet of things system under this Internet of Things resource of TLD definition, the attribute of other territory definition Internet of Things resource itself.Wherein, the naming rule of the resource identification of different Internet of things system uses is different.Wherein, adopt different bottom networking technologys, the meaning of the attribute of Internet of Things resource itself can be incomplete same.Illustrate, in the RFID network, the attribute of Internet of Things resource itself can be the type of coding of RFID label, for example EPC, ucode etc.In the WSN network; The attribute of Internet of Things resource itself can be the function type of Sensor node, for example temperature sensor (temperature transducer), humidity sensor (humidity transducer), light sensor (light transducer) or gas sensor (gas transducer) etc.In hybrid network, the attribute of Internet of Things resource itself can be the type of terminal equipment, like gateway device (Gateway).So-called resource is meant any object that can be cited, and comprises actual resource, logical resource, and the terminal equipment here also is taken as a kind of resource and treats.

The resource ownership: being similar to the original function of authority among traditional URI, being used for describing the owner of Internet of Things resource, for example can be organization name, exabyte, gateway name etc.

Wherein, when the URI of expansion was used for the standard sign, the implication of each daughter element was following:

Resource identification: be used for distinguishing different standards and identify in this locality.Wherein, said this locality can be the standard identity management system of administrative standard sign, but is not limited thereto.

Resource type: the existence form that is used for describing one type of Internet of Things resource of class standard sign institute's correspondence.For example, can be the description of classification, also can only contain TLD.

Resource ownership: being used for the maker and the manager of description standard sign, generally is national management mechanism or normal structure etc.

Step 102, terminal equipment send first query requests to standard identity management system, and the corresponding naming rule of standard sign returned after inquiring about according to first query requests of acceptance criteria identity management system.

Wherein, first query requests comprises the standard sign.

Terminal equipment is after benchmark sign that gets access to the Internet of Things resource and resource identification; Generation comprises first query requests of benchmark sign; Then query requests is sent to standard identity management system; Inquire about according to first query requests with request standard sign, obtain the corresponding naming rule of benchmark sign.

In the present embodiment, standard identity management system is mainly used in various standard signs is managed.The standard identity management system of present embodiment stores each standard sign and the corresponding information such as naming rule of each standard sign.After standard identity management system receives first query requests, can resolve, obtain the benchmark sign, search and finally obtain the corresponding naming rule of benchmark sign according to the benchmark sign then, return to terminal equipment then first query requests.Wherein, The implementation or the structure of standard identity management system can have multiple; For example can adopt the multistage standard identification server of managing with tree to realize; Also can only adopt the primary standard identification server to realize, can also adopt the multistage standard identification server that carries out organization and administration with circulus to realize.For the standard identity management system of different implementations or structure, inquiring about the process of obtaining the corresponding naming rule of standard sign according to the standard sign can be different.Present embodiment does not limit this.

Step 103, terminal equipment shine upon resource identification according to the corresponding naming rule of standard sign, obtain first address information of resource identification management system.

After terminal equipment gets access to the corresponding naming rule of standard sign, according to the corresponding naming rule of standard sign resource identification is shone upon, obtain first address information of resource identification management system.Wherein, first address information of resource identification management system mainly is meant the required address of terminal equipment access resources identity management system, and this address is looked the implementation structure of resource identification management system and understood different.For example, if the resource identification management system adopts single resource identification server implementation structure, then this address is the address of this resource identification server; If the resource identification management system adopts multistage resource identification server to realize that then this address can be the address of wherein certain resource identification server etc.

In the present embodiment, the resource identification server mainly is responsible for resource identification is managed.Wherein, storing the various information of the Internet of Things resource that each resource identification and each resource identification identifies on the resource identification management system, for example can be the information of the manufacturer of Internet of Things resource, the information of selling area etc.

Step 104, terminal equipment send second query requests according to first address information of resource identification management system to the resource identification management system, receive the resource identification management system and inquire about the first information of the Internet of Things resource of returning according to second query requests.

Terminal equipment sends second query requests according to this first address information to the resource identification management system after getting access to first address information of resource identification management system, comprise above-mentioned resource identification in second query requests.The resource identification management system is after receiving second query requests; Second query requests is resolved, obtain resource identification wherein, inquire about according to resource identification then; Obtain the information of the Internet of Things resource that this resource identification identifies, and return to terminal equipment.Wherein, according to the implementation of resource identification management system or the difference of structure, the process that the resource identification management system is inquired about according to resource identification can be different.The first information of the Internet of Things resource that terminal equipment reception resource identification management system is returned.

Wherein, the first information of Internet of Things resource can be one or more in the various information of Internet of Things resource.For example, the first information of Internet of Things resource can be information and/or the information of market etc. of the production firm of Internet of Things resource.

In the present embodiment; Use resource identification unique identification Internet of Things resource; And the naming rule of the resource identification of use standard sign definition marker networked resources; And through resource identification management system and standard identity management system two kinds of signs are managed respectively; Terminal equipment is inquired about the Internet of Things resource information based on resource identification and standard sign simultaneously, owing to identify the naming rule that can know resource identification through standard, feasible management to the Internet of Things resource, inquiry etc. no longer receive the different restriction of naming rule of resource identification in the different Internet of things system; Realized unified management, for further developing of Internet of Things lays the foundation to Internet of Things resource in the heterogeneous system.

Further, in various embodiments of the present invention, the standard sign is different from common resource identification, and the standard sign is a kind of special identifier.For example, the quantity of standard sign is far smaller than the quantity of resource identification, is generally registered by organization or management platform.The registration management of resource identification belongs to the owner of resource, if for example the RFID label of A state identifies according to the a1 rule, A state generally hopes the registration and the analysis service of this type of RFID label of own O&M so.Parsing inquiry to resource identification also possibly be a kind of behavior that needs anonymous inquiry.On the contrary, the registration management and the query parse of standard sign all are public behaviors, are to link up between various countries, area, the tissue and the basis of shared information resources.The parsing inquiry quantity of standard sign is far longer than resource identification, and the resource identification of same classification all can be resolved inquiry to public standard sign.Based on this,, may cause great pressure to the most top server if standard is identified the administrative mechanism that adopts pyramid.In order to guarantee need a kind of administrative mechanism of rational equity, and traditional DNS system can not to satisfy this demand to the registration of standard sign and the fairness and the stability of analysis service.To the problems referred to above, present embodiment provides a kind of P2P system of layering that utilizes to come the system of administrative standard sign, i.e. standard identity management system.
