Description

物联网资源信息获取方法、终端设备及*** Internet of Things resource information acquisition method, terminal device and system

技术领域 Technical field

本发明涉及物联网技术，尤其涉及一种物联网资源信息获取方法、终端设备及***。背景技术 The present invention relates to the Internet of Things technology, and in particular, to an Internet of Things resource information acquisition method, a terminal device and a system. Background technique

物联网通过自动识别和感知技术获取物品自身和周边信息，基于网络通信技术完成物品组网和与互联网的融合，借助类似互联网中域名***的基础服务发现、识别、定位、检索到物理或逻辑资源，利用普适计算技术使得人们能够在任何时间、任何地点、以任何方式处理各种信息，最终达到对现实世界的智能化决策和控制。 The Internet of Things acquires the information of the item itself and its surrounding information through automatic identification and sensing technology, completes the integration of the item network and the Internet based on the network communication technology, and discovers, identifies, locates, and retrieves physical or logical resources by using the basic service similar to the domain name system in the Internet. The use of ubiquitous computing technology enables people to process a variety of information anytime, anywhere, in any way, and ultimately achieve intelligent decision-making and control of the real world.

物联网中资源的范畴比较广泛，既包括物理资源，例如智能物体本身 (如无线传感器节点、无线射频电子标签等），也包括逻辑资源，例如智能物体自身或者其所感知的周边环境的信息。 The scope of resources in the Internet of Things is broad, including physical resources, such as smart objects themselves (such as wireless sensor nodes, radio frequency electronic tags, etc.), as well as logical resources, such as information about the smart object itself or the surrounding environment it perceives.

现有技术中，能够有效管理物联网中海量资源的技术主要有两种，分别是：面向无线射频识别（ Radio Frequency Identification, RFID )技术的对象名字月良务（ Object Name Service, ONS ) 和面向无线传感器网络 ( Wireless Sensor Network, WSN )技术的约束应用十办议（ Constrained Application Protocol, CoAP ) 。 In the prior art, there are two main technologies for effectively managing massive resources in the Internet of Things, namely: Object Name Service (ONS) and Object Orientation for Radio Frequency Identification (RFID) technology Wireless Sensor Network (WSN) technology is constrained by the Constrained Application Protocol (CoAP).

ONS釆用互联网域名解析服务（ Domain Name Service , DNS )的原理，将 RFID标签的产品电子代码 ( Electronic Product Code, EPC ) 编码解析到存有物品信息的 EPC信息服务器（ EPC Information Server, EPCIS ) 地址，是使用最为广泛的用于管理 RFID网络资源的管理服务。 ONS uses the principle of the Internet Domain Name Service (DNS) to parse the RFID product's Electronic Product Code (EPC) code to the EPC Information Server (EPCIS) address where the item information is stored. , is the most widely used management service for managing RFID network resources.

CoAP协议釆用互联网超文本传输协议 ( Hypertext Transport Protocol, HTTP ) 类似的特征，通过资源抽象、定义交互流程、扩展头选项等，在 The CoAP protocol uses similar features of the Hypertext Transport Protocol (HTTP), through resource abstraction, defining interaction flows, extending header options, etc.

( Representational State Transfer, REST )准则的服务，其主要用于管理无线传感器节点资源。面向 WSN技术和面向 RFID技术都仅仅是信息釆集技术之一。除传感技术和 RFID技术外， GPS、视频识别、红外、激光、扫描等所有能够实现自动识别以及物物通信的技术都可以成为物联网的信息釆集技术。传感网或者 RFID网只是物联网的一种应用，但绝不是物联网的全部。上述两种技术都无法保证对不同资源的兼容性管理，即无法对异构的物理资源和逻辑资源进行统一管理。发明内容本发明提供一种物联网资源获取方法、终端设备及***，用以实现对各种异构物联网资源的统一管理。 (Representational State Transfer, REST) guidelines for services that are primarily used to manage wireless sensor node resources. Both WSN technology and RFID-oriented technology are just one of the information gathering technologies. In addition to sensing technology and RFID technology, GPS, video recognition, infrared, laser, scanning and other technologies that enable automatic identification and object communication can become the information gathering technology of the Internet of Things. Sensor networks or RFID networks are just one application of the Internet of Things, but they are by no means all of the Internet of Things. The above two technologies cannot guarantee the compatibility management of different resources, that is, the unified management of heterogeneous physical resources and logical resources cannot be performed.

The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

图 1为本发明一实施例提供的物联网资源信息获取方法的流程图。如图 1所示，本实施例的方法包括： FIG. 1 is a flowchart of a method for acquiring Internet of Things resource information according to an embodiment of the present invention. As shown in FIG. 1, the method of this embodiment includes:

步骤 101、终端设备获取物联网资源的标准标识和资源标识；所述资源标识用于唯一标识物联网资源，所述标准标识用于定义资源标识的命名规则。 Step 101: The terminal device obtains a standard identifier and a resource identifier of the Internet of Things resource, where the resource identifier is used to uniquely identify the Internet of Things resource, and the standard identifier is used to define a naming rule of the resource identifier.

本实施例的终端设备可以是各种物联网应用终端设备，如通过 Web 服务访问物联网资源的用户终端（例如智能手机）、直接管理控制物联网资源的智能网关等。 The terminal device of this embodiment may be various IoT application terminal devices, such as a user terminal (for example, a smart phone) that accesses an Internet of Things resource through a Web service, and an intelligent gateway that directly controls an IoT resource.

本实施例的物联网资源可以是物联网***中的物理资源，例如无线传感器节点、无线射频电子标签等，也可以是物联网***中的逻辑资源，例如文本、音频、视频等。 The Internet of Things resource of this embodiment may be a physical resource in an Internet of Things system, such as wireless transmission. Sensor nodes, radio frequency electronic tags, etc., can also be logical resources in the Internet of Things system, such as text, audio, video, and so on.

在本实施例中，物联网资源同时使用标准标识和资源标识来标识。其中，物联网资源的标准标识和资源标识通常存储在物联网资源中。终端设备可以直接从物联网资源上获取该物联网资源的标准标识和资源标识。例如，如果物联网资源为无线传感器节点，则终端设备可以通过与无线传感器节点进行信息交互，获取无线传感器节点的标准标识和资源标识。又例如，如果物联网资源为逻辑资源，则该逻辑资源的标准标识和资源标识会作为该逻辑资源的一部分携带在该逻辑资源中，基于此，终端设备可以直接从逻辑资源中获取其标准标识和资源标识。 In this embodiment, the Internet of Things resources are simultaneously identified by using standard identifiers and resource identifiers. Among them, the standard identification and resource identification of IoT resources are usually stored in IoT resources. The terminal device can obtain the standard identifier and resource identifier of the IoT resource directly from the IoT resource. For example, if the IoT resource is a wireless sensor node, the terminal device can obtain the standard identifier and resource identifier of the wireless sensor node by performing information interaction with the wireless sensor node. For example, if the IoT resource is a logical resource, the standard identifier and the resource identifier of the logical resource are carried in the logical resource as part of the logical resource. Based on this, the terminal device can directly obtain the standard identifier from the logical resource. And resource identification.

其中，所述各种标识就是一种用于识别不同对象的命名符号。物联网资源的资源标识（ Resource Identifier, RID ) 主要用于唯一标识物联网资源，而物联网资源的标准标识（ Standard Identifier, SID )主要用于定义物联网资源的资源标识的命名规则。 Wherein, the various identifiers are a named symbol for identifying different objects. The Resource Identifier (RID) of the IoT resource is mainly used to uniquely identify the Internet of Things resources. The Standard Identifier (SID) of the IoT resource is mainly used to define the naming rules of the resource identifier of the Internet of Things resources.

传统的统一资源标识符（ Uniform Resource Identifier, URI )仅用来识别网络（Web ) 资源，例如 URI的基本格式是： The traditional Uniform Resource Identifier (URI) is only used to identify network (Web) resources. For example, the basic format of a URI is:

<URI>: :=<scheme>:<scheme-specific-part> , 由命名大纲的名称 (即 <URI>: :=<scheme>:<scheme-specific-part> , by the name of the naming outline (ie

<scheme>部分）和釆用该命名大纲生成的唯一标识符（即 <scheme> section) and the unique identifier generated by the naming convention (ie

<scheme-specific-part>部分）组成，名称和标识符之间用 "： " 分隔。 <scheme-specific-part> section) The composition, name and identifier are separated by ":".

URI的基本格式中的<8(；1^11½-8 6(^ &11>部分通常由 4个部分组成，即 <scheme-specific-part>:： =<authority> [<path>] [？ <query>] [#<fragment>]。 The <8(;1^111⁄2-8 6(^ &11> part of the basic format of the URI is usually composed of 4 parts, ie <scheme-specific-part>:: =<authority> [<path>] [? < Query>] [#<fragment>].

其中， authority是釆用该命名大纲的机构代码，即存放物联网资源的主机名。 path是存放物联网资源的相对路径信息，以 "/"作为间隔。 query 是由 "属性 -值" 对组成的检索表达式，以 "？ " 开头。 fragment是标识相对于主资源的子资源，以 "#" 开头。 Among them, authority is the organization code that uses the naming outline, that is, the host name of the IoT resource. Path is the relative path information for storing IoT resources, with "/" as the interval. Query is a retrieval expression consisting of a "property-value" pair, starting with "?". A fragment is a sub-resource that identifies a primary resource, starting with "#".

其中 authority是必选属性 , 而 path和 query、 fragment是可选属性。可选的，本实施例的标准标识和资源标识均可以通过扩展的 URI来实现。 Where authority is a mandatory attribute, and path and query, fragment are optional attributes. Optionally, the standard identifier and the resource identifier of this embodiment can be implemented by using an extended URI.

可选的，本实施例提供的一种扩展的 URI的结构，主要是将原有的主机名称 <authority:^;"展为资源名称 <resource>。可选的, 本实施例的资源名称< 80111^6>又可由资源标识、资源类型、资源归属三部分组成。 Optionally, the structure of the extended URI provided in this embodiment is mainly to display the original host name <authority:^;" as the resource name <resource>. Optionally, the resource name in this embodiment It can be said that <80111^6> can be composed of three parts: resource identification, resource type and resource attribution.

其中，当扩展的 URI用于资源标识时，各子元素的含义如下： Wherein, when the extended URI is used for resource identification, the meaning of each sub-element is as follows:

资源标识：用于在本地区分不同的物联网资源，可由物联网子域中各异构网络管理者根据本地命名原则来标识物联网资源。所述本地可以是管理资源标识的资源标识管理***，但不限于此。 Resource identification: Used to distinguish different IoT resources locally. Io network resources can be identified by different network managers in the IoT subdomain according to local naming principles. The local may be a resource identification management system that manages resource identification, but is not limited thereto.

资源类型：用来描述物联网资源的存在形式。例如，可以是分级的描述，例如，顶级域定义该物联网资源所属的物联网***的类型，其它域定义物联网资源本身的属性。其中，不同物联网***使用的资源标识的命名规则是不同的。其中，釆用不同的底层组网技术，物联网资源本身的属性的意义会不完全相同。举例说明，在 RFID网络中，物联网资源本身的属性可以是 RFID标签的编码类型，例如 EPC、 ucode等。在 WSN网络中，物联网资源本身的属性可以是 Sensor节点的功能类型，例如温度传感器 ( temperature transducer ) 、湿度传感器 ( humidity transducer ) 、光敏传感器（ light transducer )或气敏传感器（ gas transducer )等。在混合网络中，物联网资源本身的属性可以是终端设备的类型，如网关设备（Gateway ) 。所谓资源，是指任何可以被引用的对象，包括实体资源、逻辑资源，这里的终端设备也被当作一种资源看待。 Resource Type: Used to describe the existence of IoT resources. For example, it can be a hierarchical description, for example, the top-level domain defines the type of IoT system to which the IoT resource belongs, and the other domain defines the properties of the IoT resource itself. Among them, the naming rules for resource identifiers used by different IoT systems are different. Among them, different underlying networking technologies are used, and the meaning of the attributes of the Internet of Things resources is not exactly the same. For example, in an RFID network, the property of the IoT resource itself may be an encoding type of an RFID tag, such as EPC, ucode, or the like. In a WSN network, the attributes of the IoT resource itself may be the type of function of the Sensor node, such as a temperature transducer, a humidity transducer, a light transducer, or a gas transducer. In a hybrid network, the attributes of the IoT resource itself may be the type of the terminal device, such as a gateway device (Gateway). The so-called resource refers to any object that can be referenced, including entity resources and logical resources. The terminal device here is also treated as a resource.

资源归属：类似于传统 URI中 authority的原有功能，用来描述物联网资源的拥有者，例如可以是组织名、公司名、网关名等。 Resource attribution: Similar to the original function of the authority in the traditional URI, it is used to describe the owner of the Internet of Things resources, such as the organization name, company name, gateway name, etc.

其中，当扩展的 URI用于标准标识时，各子元素的含义如下：资源标识：用来在本地区分不同的标准标识。其中，所述本地可以是管理标准标识的标准标识管理***，但不限于此。 Wherein, when the extended URI is used for the standard identifier, the meaning of each sub-element is as follows: Resource identifier: Used to distinguish different standard identifiers locally. The local may be a standard identity management system that manages the standard identifier, but is not limited thereto.

资源类型：用来描述一类标准标识所对应一类物联网资源的存在形式。例如，可以是分级的描述，也可以只含有顶级域。 Resource Type: Used to describe the existence of a type of IoT resource corresponding to a type of standard identifier. For example, it can be a hierarchical description or just a top-level domain.

资源归属：用来描述标准标识的制定者和管理者，一般是国家管理机构或标准组织等。 Resource attribution: The setter and manager used to describe the standard identifier, usually a national regulatory agency or a standard organization.

步骤 102、终端设备向标准标识管理***发送第一查询请求，并接收标准标识管理***根据第一查询请求进行查询后返回的标准标识对应的命名规则。 Step 102: The terminal device sends a first query request to the standard identifier management system, and receives a naming rule corresponding to the standard identifier returned by the standard identifier management system according to the first query request.

其中，第一查询请求包括标准标识。终端设备在获取到物联网资源的基准标识和资源标识之后，生成包括基准标识的第一查询请求，然后将查询请求发送给标准标识管理***，以请求标准标识根据第一查询请求进行查询，获取基准标识对应的命名规则。 The first query request includes a standard identifier. After acquiring the reference identifier and the resource identifier of the IoT resource, the terminal device generates a first query request including the reference identifier, and then sends the query request to the standard identifier management system to request the standard identifier to perform query according to the first query request, and obtain The naming rules for the baseline ID.

在本实施例中，标准标识管理***主要用于对各种标准标识进行管理。本实施例的标准标识管理***存储有各标准标识以及各标准标识对应的命名规则等信息。标准标识管理***接收到第一查询请求后，可以对第一查询请求进行解析，获取基准标识，然后根据基准标识进行查找并最终获取基准标识对应的命名规则，然后返回给终端设备。其中，标准标识管理***的实现方式或结构可以有多种，例如可以釆用多级以树状结构进行管理的标准标识服务器实现，也可以只釆用一级标准标识服务器实现，还可以釆用多级以环状结构进行组织管理的标准标识服务器来实现。对于不同实现方式或结构的标准标识管理***来说，根据标准标识进行查询获取标准标识对应的命名规则的过程可以有所不同。本实施例对此不作限定。 In this embodiment, the standard identification management system is mainly used to manage various standard identifications. The standard identification management system of this embodiment stores information such as each standard identifier and a naming rule corresponding to each standard identifier. After receiving the first query request, the standard identifier management system may parse the first query request, obtain the reference identifier, and then search according to the reference identifier and finally obtain the naming rule corresponding to the reference identifier, and then return to the terminal device. The standard identifier management system may be implemented in multiple ways, for example, by using a standard identifier server managed by a multi-level tree structure, or by using a first-level standard identifier server, or by using a standard identifier server. The multi-level standard identification server is organized and managed in a ring structure. For a standard identity management system with different implementations or structures, the process of querying the naming rules corresponding to the standard identifier according to the standard identifier may be different. This embodiment does not limit this.

步骤 103、终端设备根据标准标识对应的命名规则对资源标识进行映射，获取资源标识管理***的第一地址信息。 Step 103: The terminal device maps the resource identifier according to the naming rule corresponding to the standard identifier, and obtains the first address information of the resource identifier management system.

当终端设备获取到标准标识对应的命名规则之后，根据标准标识对应的命名规则对资源标识进行映射，获取资源标识管理***的第一地址信息。其中，资源标识管理***的第一地址信息主要是指终端设备访问资源标识管理***所需的地址，该地址视资源标识管理***的实现结构会有所不同。例如，如果资源标识管理***釆用单一资源标识服务器实现结构，则该地址即为该资源标识服务器的地址；如果资源标识管理***釆用多级资源标识服务器实现，则该地址可以是其中某个资源标识服务器的地址等。 After the terminal device obtains the naming rule corresponding to the standard identifier, the resource identifier is mapped according to the naming rule corresponding to the standard identifier, and the first address information of the resource identifier management system is obtained. The first address information of the resource identifier management system mainly refers to an address required by the terminal device to access the resource identifier management system, and the address may be different depending on the implementation structure of the resource identifier management system. For example, if the resource identification management system uses a single resource to identify the server implementation structure, the address is the address of the resource identification server; if the resource identification management system is implemented by the multi-level resource identification server, the address may be one of them. The resource identifies the address of the server, and so on.

在本实施例中，资源标识服务器主要负责对资源标识进行管理。其中，资源标识管理***上存储有各资源标识以及各资源标识所标识的物联网资源的各种信息，例如可以是物联网资源的生产厂家的信息、销售场地的信息等。 In this embodiment, the resource identifier server is mainly responsible for managing the resource identifier. The resource identifier management system stores various information about the resource identifiers and the Internet of Things resources identified by the resource identifiers, for example, information of the manufacturer of the Internet of Things resources, information of the sales venue, and the like.

步骤 104、终端设备根据资源标识管理***的第一地址信息向资源标识管理***发送第二查询请求，接收资源标识管理***根据第二查询请求进行查询返回的物联网资源的第一信息。 Step 104: The terminal device sends a second query request to the resource identifier management system according to the first address information of the resource identifier management system, and the received resource identifier management system receives the second query request according to the second query request. The first information of the IoT resource returned by the query.

终端设备在获取到资源标识管理***的第一地址信息后，根据该第一地址信息向资源标识管理***发送第二查询请求，第二查询请求中包括上述资源标识。资源标识管理***在接收到第二查询请求后，对第二查询请求进行解析，获取其中的资源标识，然后根据资源标识进行查询，获取该资源标识所标识的物联网资源的信息，并返回给终端设备。其中，根据资源标识管理***的实现方式或结构的不同，资源标识管理***根据资源标识进行查询的过程可以有所不同。终端设备接收资源标识管理***返回的物联网资源的第一信息。 After acquiring the first address information of the resource identifier management system, the terminal device sends a second query request to the resource identifier management system according to the first address information, where the second query request includes the resource identifier. After receiving the second query request, the resource identifier management system parses the second query request, obtains the resource identifier, and then performs a query according to the resource identifier, and obtains the information of the Internet of Things resource identified by the resource identifier, and returns the information to the resource identifier. Terminal Equipment. The process of querying the resource identification management system according to the resource identification may be different according to the implementation manner or structure of the resource identification management system. The terminal device receives the first information of the Internet of Things resource returned by the resource identification management system.

其中，物联网资源的第一信息可以是物联网资源的各种信息中的一种或几种。例如，物联网资源的第一信息可以是物联网资源的生产厂商的信息和 /或销售地的信息等。 The first information of the Internet of Things resource may be one or more of various information of the Internet of Things resources. For example, the first information of the Internet of Things resource may be the information of the manufacturer of the Internet of Things resources and/or the information of the place of sale.

在本实施例中，使用资源标识唯一标识物联网资源，并使用标准标识定义标识物联网资源的资源标识的命名规则，并分别通过资源标识管理系统和标准标识管理***对两种标识进行管理，终端设备同时基于资源标识和标准标识对物联网资源信息进行查询，由于通过标准标识可以获知资源标识的命名规则，使得对物联网资源的管理、查询等不再受不同物联网系统中资源标识的命名规则不同的限制，实现了对异构***中物联网资源的统一管理，为物联网的进一步发展打下了基础。 In this embodiment, the resource identifier is used to uniquely identify the Internet of Things resource, and the standard identifier is used to define a naming rule for identifying the resource identifier of the Internet of Things resource, and the two identifiers are managed by the resource identifier management system and the standard identifier management system respectively. The terminal device queries the IoT resource information based on the resource identifier and the standard identifier. The naming rules of the resource identifier can be obtained through the standard identifier, so that the management, query, and the like of the Internet of Things resources are no longer subject to resource identification in different IoT systems. Different restrictions on naming rules have realized the unified management of IoT resources in heterogeneous systems, laying a foundation for the further development of the Internet of Things.

进一步，在本发明各实施例中，标准标识不同于普通的资源标识，标准标识是一种特殊的标识符。例如，标准标识的数量远远小于资源标识的数量，一般由组织机构或管理平台进行注册。资源标识的注册管理属于资源的拥有者，例如 A国的 RFID标签如果按照 al规则进行标识，那么 A 国一般希望自己运维此类 RFID标签的注册和解析服务。对资源标识的解析查询也可能是一种需要匿名查询的行为。相反，标准标识的注册管理和查询解析都是公共行为，是各国家、地区、组织之间进行沟通和共享信息资源的基础。标准标识的解析查询数量远远大于资源标识，同一类别的资源标识都会对公共的标准标识进行解析查询。基于此，如果对标准标识釆用金字塔式的管理机制，可能会对最顶级的服务器造成极大的压力。为了保证对标准标识的注册和解析服务的公平性和稳定性，需要一种合理的对等的管理机制，而传统的 DNS***不能满足这一需求。针对上述问题，本实施例提供一种利用分层的 P2P***来管理标准标识的***，即标准标识管理***。 Further, in various embodiments of the present invention, the standard identifier is different from the normal resource identifier, and the standard identifier is a special identifier. For example, the number of standard identifiers is much smaller than the number of resource identifiers, and is generally registered by an organization or management platform. The registration management of the resource identifier belongs to the owner of the resource. For example, if the RFID tag of country A is identified according to the al rule, then country A generally wishes to operate and register the registration and resolution service of such an RFID tag. A parsing query for a resource identifier may also be an act that requires an anonymous query. On the contrary, the registration management and query resolution of standard identification are public behaviors, which are the basis for communication and sharing of information resources between countries, regions and organizations. The number of parsing queries for the standard ID is much larger than the resource ID. The resource ID of the same category will be parsed and queried for the public standard ID. Based on this, if you use a pyramidal management mechanism for the standard logo, it may put a lot of pressure on the top server. In order to ensure the fairness and stability of the registration and resolution services of the standard identification, a reasonable pair is needed. And other management mechanisms, and the traditional DNS system can not meet this demand. In view of the above problems, the embodiment provides a system for managing a standard identifier by using a layered P2P system, that is, a standard identifier management system.

可选的，本实施例可以利用现有的 DNS基础设施来构建对应的分层标准标识服务器，进而形成标准标识管理***。 Optionally, the embodiment may use an existing DNS infrastructure to construct a corresponding hierarchical standard identifier server, thereby forming a standard identity management system.

在本实施例中，一种标准标识管理***包括三级标准标识服务器，分别为第一级标准标识服务器、第二级标准标识服务器和第三级标准标识服务器。其中，每一级可以有多个标准标识服务器，这些标准标识服务器在逻辑上构成环状结构。 In this embodiment, a standard identification management system includes a three-level standard identification server, which is a first-level standard identification server, a second-level standard identification server, and a third-level standard identification server. There may be multiple standard identification servers at each level, and these standard identification servers logically form a ring structure.

第一级标准标识服务器，例如可以是根标准标识服务器（Root- The first level standard identification server, for example, can be the root standard identification server (Root-

Standard name server, R-SNS ) ：是标准标识管理***中最高级别的标准标识服务器，负责维护不同国家或者地区的映射列表。第二级标准标识服务器，例如可以是国家 /地区标准标识服务器（ National- Standard name server, N-SNS )：负责维护国家或地区不同标准组织的映射列表。第三级标准标识服务器，例如可以是组织 /机构标准标识服务器（ Organization- Standard name server, O-SNS ) ：负责维护组织或者机构级别的标准标识管理，管理 RFID标签、 WSN传感器节点等具体标识的命名规则。 Standard name server, R-SNS ): is the highest level standard identification server in the standard identification management system, responsible for maintaining mapping lists of different countries or regions. The second level standard identification server, for example, can be a National-Standard Name Server (N-SNS): A list of mappings responsible for maintaining different standards organizations in a country or region. The third-level standard identification server, for example, may be an Organization-Standard name server (O-SNS): responsible for maintaining standard identification management at the organization or organization level, and managing specific identifiers such as RFID tags and WSN sensor nodes. Naming rules.

基于上述标准标识管理***的三级实现结构，步骤 102的一种具体实施方式可以包括： Based on the three-level implementation structure of the foregoing standard identifier management system, a specific implementation of step 102 may include:

可选的，终端设备可以在标准标识后面添加物联网资源所属的资源类型和域名后缀，获取标准标识管理***的第一地址信息。其中，第一地址信息是指标准标识管理***中多个第一级标准标识服务器中的一个明确的第一级标准标识服务器的访问地址。然后，终端设备根据标准标识管理 ***的第一地址信息，向该第一地址信息对应的第一级标准标识服务器发送第一查询请求。 Optionally, the terminal device may add the resource type and the domain name suffix to which the IoT resource belongs to the standard identifier, and obtain the first address information of the standard identifier management system. The first address information refers to an access address of an explicit first-level standard identifier server of the plurality of first-level standard identifier servers in the standard identifier management system. Then, the terminal device sends the first address information corresponding to the first address information to the first level standard identifier server corresponding to the first address information according to the first address information of the standard identifier management system. Send the first query request.

对第一级标准标识服务器来说，第一级标准标识服务器接收终端设备发送的第一查询请求，根据第一查询请求中的标准标识在本地进行查询，如果查询到标准标识对应的命名规则，则将查询到的标准标识对应的命名规则发送给终端设备；如果没有查询到标准标识对应的命名规则，则向终端设备返回一个第二级标准标识服务器的访问地址。在此说明，对于存在多个第一级标准标识服务器的情况，如果一个第一级标准标识服务器在本地未查询到标准标识对应的命名规则，可以将第一查询请求转发给下一个第一级标准标识服务器，由下一个第一级标准标识服务器继续进行查询直到向终端设备返回成功查询到标准标识对应的命名规则，或者直到向终端设备返回第二级标准标识服务器的访问地址为止。其中，第二级标准标识服务器的访问地址是指终端设备访问第二级标准标识服务器所需的地址信息，也就是第二级标准标识服务器的地址，例如 IP地址或 MAC地址等。 For the first-level standard identifier server, the first-level standard identifier server receives the first query request sent by the terminal device, and performs local query according to the standard identifier in the first query request, and if the naming rule corresponding to the standard identifier is queried, Then, the naming rule corresponding to the queried standard identifier is sent to the terminal device; if the naming rule corresponding to the standard identifier is not queried, the access address of the second-level standard identifier server is returned to the terminal device. In this case, if there is a plurality of first-level standard identifier servers, if a first-level standard identifier server does not query the naming rule corresponding to the standard identifier locally, the first query request may be forwarded to the next first level. The standard identification server continues the query by the next first-level standard identification server until the naming rule corresponding to the standard identifier is successfully returned to the terminal device, or until the access address of the second-level standard identification server is returned to the terminal device. The access address of the second-level standard identifier server refers to the address information required by the terminal device to access the second-level standard identifier server, that is, the address of the second-level standard identifier server, such as an IP address or a MAC address.

终端设备接收第一级标准标识服务器在查询到标准标识对应的命名规则后返回的标准标识对应的命名规则。或者终端设备接收第一级标准标识服务器在未查询到标准标识对应的命名规则后返回的第二级标准服务器的访问地址。 The terminal device receives the naming rule corresponding to the standard identifier returned by the first-level standard identifier server after querying the naming rule corresponding to the standard identifier. Or the terminal device receives the access address of the second-level standard server returned by the first-level standard identification server after the naming rule corresponding to the standard identifier is not queried.

The first query request is such that the second level standard identification server queries according to the standard identifier and returns the query result.

对第二级标准标识服务器来说，第二级标准标识服务器接收终端设备发送的第一查询请求，根据第一查询请求中的标准标识在本地进行查询，如果查询到标准标识对应的命名规则，则将查询到的标准标识对应的命名规则发送给终端设备；如果没有查询到标准标识对应的命名规则，则向终端设备返回一个第三级标准标识服务器的访问地址。在此说明，对于存在多个第二级标准标识服务器的情况，如果一个第二级标准标识服务器在本地未查询到标准标识对应的命名规则，可以将第一查询请求转发给下一个第二级标准标识服务器，由下一个第二级标准标识服务器继续进行查询直到向终端设备返回成功查询到标准标识对应的命名规则，或者直到向终端设备返回第三级标准服务器的访问地址为止。其中，第三级标准标识服务器的访问地址是指终端设备访问第三级标准标识服务器所需的地址信息，也就是第三级标准标识服务器的地址，例如 IP地址或 MAC地址等。 For the second-level standard identifier server, the second-level standard identifier server receives the first query request sent by the terminal device, and performs local query according to the standard identifier in the first query request, and if the naming rule corresponding to the standard identifier is queried, Then, the naming rule corresponding to the queried standard identifier is sent to the terminal device; if the naming rule corresponding to the standard identifier is not queried, the access address of the third-level standard identifier server is returned to the terminal device. In this case, if there is a plurality of second-level standard identifier servers, if a second-level standard identifier server does not query the naming rule corresponding to the standard identifier locally, the first query request may be forwarded to the next second level. The standard identification server continues to perform the query by the next second-level standard identification server until the naming rule corresponding to the standard identifier is successfully returned to the terminal device, or until the terminal is The device returns to the access address of the third-level standard server. The access address of the third-level standard identifier server refers to the address information required by the terminal device to access the third-level standard identifier server, that is, the address of the third-level standard identifier server, such as an IP address or a MAC address.

Alternatively, the terminal device receives the access address of the third-level standard identification server that is returned by the second-level standard identification server when the naming rule corresponding to the standard identifier is not queried.

The first query request is such that the third level standard identification server queries according to the standard identifier and returns the query result.

对第三级标准标识服务器来说，第三级标准标识服务器接收终端设备发送的第一查询请求，根据第一查询请求中的标准标识在本地进行查询，如果查询到标准标识对应的命名规则，则将查询到的标准标识对应的命名规则发送给终端设备；如果没有查询到标准标识对应的命名规则，则可以向终端设备返回查询失败的信息。在此说明，对于存在多个第三级标准标识服务器的情况，如果一个第三级标准标识服务器在本地未查询到标准标识对应的命名规则，可以将第一查询请求转发给下一个第三级标准标识服务器，由下一个第三级标准标识服务器继续进行查询直到向终端设备返回成功查询到标准标识对应的命名规则，或者直到向终端设备返回查询失败的消息为止。 For the third-level standard identifier server, the third-level standard identifier server receives the first query request sent by the terminal device, and performs local query according to the standard identifier in the first query request. If the naming rule corresponding to the standard identifier is queried, Then, the naming rule corresponding to the queried standard identifier is sent to the terminal device; if the naming rule corresponding to the standard identifier is not queried, the information that the query fails may be returned to the terminal device. In this case, if there is a plurality of third-level standard identifier servers, if a third-level standard identifier server does not query the naming rule corresponding to the standard identifier locally, the first query request may be forwarded to the next third level. The standard identification server continues the query by the next third-level standard identification server until the naming rule corresponding to the standard identifier is successfully returned to the terminal device, or until the message that the query fails is returned to the terminal device.

在本发明各实施例中，物联网资源的管理权属于物联网资源的拥有者，如果拥有者没有能力直接管理所属资源，可以进行委托，由可信的第三方进行管理。对应于资源标识的管理也是这样。但是，在现有物联网资源管理中，多数情况是将资源标识集中委托于某一个国家或者组织、公司。这种集中式管理资源标识的方式一方面很容易遭到 DDoS等安全攻击，另一方面，这种基于单一管理的物联网应用过度依赖于该唯一管理机构，如果该管理机构因为政治、经济等原因滥用管理权，那么物联网应用的安全性从根本上无法得到保证。 In various embodiments of the present invention, the management right of the Internet of Things resource belongs to the owner of the Internet of Things resource. If the owner does not have the ability to directly manage the resource, the client may be delegated and managed by a trusted third party. The same is true for the management of the resource identifier. However, in the existing IoT resource management, most of the cases are to centrally delegate the resource identification to a certain country or organization or company. This centralized management of resource identification is vulnerable to security attacks such as DDoS on the one hand. On the one hand, this kind of IoT application based on single management relies too much on the unique management organization. If the management agency abuses management rights for political and economic reasons, the security of the Internet of Things application cannot be guaranteed at all.

针对上述问题，本发明实施例提供一种资源标识管理***，该资源标识管理***可以利用现有的 DNS基础设施，设立相应的分层资源标识服务器，通过多层资源标识服务器对不同级别的资源标识进行管理，而不再基于某一个管理机构对资源标识进行统一管理，从而克服集中管理资源标识的各种缺陷。其中，资源标识管理***中资源标识服务器的层数不做限定。 In response to the above problem, an embodiment of the present invention provides a resource identifier management system, which can use an existing DNS infrastructure to set up a corresponding hierarchical resource identifier server, and identify resources of different levels through a multi-layer resource identifier server. The identity is managed, and the resource identification is not uniformly managed based on a certain management organization, thereby overcoming various defects of centralized management resource identification. The number of layers of the resource identifier server in the resource identifier management system is not limited.

可选的，资源标识管理***可以釆用三级结构实现，即包括第一级资源标识服务器、第二级资源标识服务器和第三级资源标识服务器。 Optionally, the resource identifier management system can be implemented in a three-level structure, that is, includes a first-level resource identifier server, a second-level resource identifier server, and a third-level resource identifier server.

其中，第一级资源标识服务器，可以是根资源名服务器（Root-Resource name server, R-RNS ) ：是资源标识管理***中最高级别的资源标识月良务器。第二级资源标识服务器，可以是国家 /地区资源名服务器 The first-level resource identifier server may be a root-resource name server (R-RNS): the highest-level resource identifier server in the resource identifier management system. Second-level resource identification server, which can be a country/region resource name server

( National-Resource name server, N-RNS ) ：主要负责对物联网***中国家或者地区级别的资源名称的管理。第三级资源标识服务器，可以是本地资源名服务器（ Local-Resource name server, L-RNS ) ：主要负责物联网 ***中公司、企业级别的资源标识的管理。 (National-Resource name server, N-RNS): Mainly responsible for the management of resource names in the IoT system at the national or regional level. The third-level resource identification server can be a local-resource name server (L-RNS): It is mainly responsible for the management of company and enterprise-level resource identifiers in the Internet of Things system.

可选的，对每级资源标识服务器来说可以有多个。即在资源标识管理系统中，可以存在多个第一级资源标识服务器，也可以存在多个第二级资源标识服务器，也可以存在多个第三级资源标识服务器。 Optionally, there may be multiple for each level of resource identification server. That is, in the resource identification management system, there may be multiple first-level resource identification servers, multiple second-level resource identification servers, or multiple third-level resource identification servers.

The access address of the second-level resource identifier server refers to the address information required by the terminal device to access the second-level resource identifier server, that is, the address of the second-level resource identifier server, such as an IP address or a MAC address.

终端设备接收第一级资源标识服务器在根据资源标识查询到物联网资源的第一信息时返回的物联网资源的第一信息。或者，终端设备接收第一级资源标识服务器在未根据资源标识查询到物联网资源的第一信息时返回的资源标识管理***中第二级资源标识服务器的访问地址。 The terminal device receives the first information of the IoT resource returned by the first-level resource identifier server when the first information of the Internet of Things resource is queried according to the resource identifier. Alternatively, the terminal device receives the access address of the second-level resource identifier server in the resource identifier management system returned by the first-level resource identifier server when the first information of the Internet of Things resource is not queried according to the resource identifier.

当终端设备接收到第一级资源标识服务器返回的第二级资源标识服务器的访问地址后，终端设备根据第二级资源标识服务器的访问地址，向第二级资源标识服务器发送包括资源标识的第二查询请求，以使第二级资源标识服务器根据资源标识进行查询并返回查询结果。 After the terminal device receives the access address of the second-level resource identifier server returned by the first-level resource identifier server, the terminal device sends the identifier including the resource identifier to the second-level resource identifier server according to the access address of the second-level resource identifier server.

对第二级资源标识服务器来说，第二资源标识服务器接收终端设备发送的第二查询请求，根据第二查询请求中的资源标识在本地进行查询，如果根据该资源标识查询到物联网资源的第一信息，则向终端设备返回物联网资源的第一信息；如果未根据该资源标识查询到物联网资源的第一信息，则向终端设备返回资源标识管理***中第三级资源标识服务器的访问地址。在此说明，对于存在多个第二级资源标识服务器的情况，如果一个第二级标准标识服务器在本地未查询到资源标识所标识的物联网资源的第一信息，则可以将第二查询请求转发给下一个第二级资源标识服务器，由下一个第二级资源标识服务器继续进行查询直到向终端设备返回成功查询到该资源标识所标识的物联网资源的第一信息，或者直到向终端设备返回第三级资源标识服务器的访问地址为止。其中，第三级资源标识服务器的访问地址是指终端设备访问第三级资源标识服务器所需的地址信息，也就是第三级资源标识服务器的地址，例如 IP地址或 MAC地址等。终端设备接收第二级资源标识服务器在根据资源标识查询到物联网资源的第一信息时返回的物联网资源的第一信息。或者。终端设备接收第二级资源标识服务器在未根据资源标识查询到物联网资源的信息时返回的资源标识管理***的第三级资源标识服务器的访问地址。 For the second-level resource identification server, the second resource identification server receives the second query request sent by the terminal device, and performs local query according to the resource identifier in the second query request, if the IoT resource is queried according to the resource identifier. Receiving, by the first information, the first information of the IoT resource to the terminal device; if the first information of the IoT resource is not queried according to the resource identifier, returning the third-level resource identification server of the resource identifier management system to the terminal device address. It is noted that, in the case that there are multiple second-level resource identifier servers, if a second-level standard identifier server does not locally query the first information of the Internet of Things resources identified by the resource identifier, the second query request may be Forwarding to the next second-level resource identifier server, the next second-level resource identifier server continues to perform the query until the first information of the IoT resource identified by the resource identifier is successfully queried to the terminal device, or until the terminal device is Returns the access address of the third-level resource identifier server. The access address of the third-level resource identifier server refers to the address information required by the terminal device to access the third-level resource identifier server, that is, the address of the third-level resource identifier server, such as an IP address or a MAC address. The terminal device receives the first information of the Internet of Things resource returned by the second-level resource identifier server when the first information of the Internet of Things resource is queried according to the resource identifier. or. The terminal device receives the access address of the third-level resource identifier server of the resource identifier management system that is returned by the second-level resource identifier server when the information of the Internet of Things resource is not queried according to the resource identifier.

当终端设备接收到第二级资源标识服务器返回的第三级资源标识服务器的访问地址后，终端设备根据第三级资源标识服务器的访问地址，向第三级资源标识服务器发送第二查询请求，以使第三级资源标识服务器根据资源标识进行查询并返回查询结果。 After the terminal device receives the access address of the third-level resource identifier server returned by the second-level resource identifier server, the terminal device sends a second query request to the third-level resource identifier server according to the access address of the third-level resource identifier server. So that the third-level resource identification server queries according to the resource identifier and returns the query result.

对第三级资源标识服务器来说，第三资源标识服务器接收终端设备发送的第二查询请求，根据第二查询请求中的资源标识在本地进行查询，如果根据该资源标识查询到物联网资源的第一信息，则向终端设备返回物联网资源的第一信息；如果未根据该资源标识查询到物联网资源的第一信息，则可以向终端设备返回查询失败的信息。在此说明，对于存在多个第三级资源标识服务器的情况，如果一个第三级标准标识服务器在本地未查询到资源标识所标识的物联网资源的第一信息，则可以将第二查询请求转发给下一个第三级资源标识服务器，由下一个第三级资源标识服务器继续进行查询直到向终端设备返回成功查询到该资源标识所标识的物联网资源的第一信息，或者直到向终端设备返回查询失败的消息为止。 For the third-level resource identifier server, the third resource identifier server receives the second query request sent by the terminal device, and performs local query according to the resource identifier in the second query request, if the identifier of the Internet of Things resource is queried according to the resource identifier The first information is used to return the first information of the Internet of Things resource to the terminal device. If the first information of the Internet of Things resource is not queried according to the resource identifier, the information that the query fails may be returned to the terminal device. Here, in the case that there are multiple third-level resource identification servers, if a third-level standard identification server does not locally query the first information of the Internet of Things resources identified by the resource identifier, the second query request may be Forwarding to the next third-level resource identifier server, the next third-level resource identifier server continues to query until the first information of the IoT resource identified by the resource identifier is successfully queried to the terminal device, or until the terminal device is Returns the message that the query failed.

本实施例方式基于 DNS技术构建了分层的资源标识管理***，并提供了高效的物联网资源解析服务，为保证物联网资源管理的公平对等性做出了贡献。 In this embodiment, a hierarchical resource identification management system is constructed based on the DNS technology, and an efficient IoT resource analysis service is provided, which contributes to ensuring the fairness of the Internet of Things resource management.

在此说明，在具体实现上，第一级资源标识服务器和第一级标准标识服务器可以是同一物理设备，也可以是独立的物理设备；第二级资源标识服务器和第二级标准标识服务器可以是同一物理设备，也可以是独立的物理设备；第三级资源标识服务器和第三级标准标识服务器可以是同一物理设备，也可以是独立的物理设备。 It is noted that, in a specific implementation, the first-level resource identifier server and the first-level standard identifier server may be the same physical device or an independent physical device; the second-level resource identifier server and the second-level standard identifier server may be The same physical device or the independent physical device; the third-level resource identification server and the third-level standard identification server may be the same physical device or an independent physical device.

更进一步，获取物联网资源信息的过程包括：对一类物联网资源的解析查询（ Class Resource Resolve, CRR ) 和对单个资源的解析查询（Item Resource Resolve, IRR ) 。其中，对 CRR查询来说，资源标识服务器返回的结果往往是拥有这一类物联网资源的共性信息的管理者的标识；例如用 RFID标签标识物品时， CRR查询的结果可以是物品生产商的信息服务器的名称或 URL等。对 IRR查询来说，资源标识服务器可能需要经过多次递归，最终返回的结果才会是单个物联网资源对应的交互通信地址或资源属性信息等，而中间返回的是进行递归查询时对应的资源标识服务器的 URL。 Further, the process of obtaining information of the Internet of Things resources includes: a Class Resource Resolve (CRR) for a type of IoT resource and a parsing query for a single resource (Item Resource Resolve, IRR ). For the CRR query, the result returned by the resource identification server is often the identifier of the manager who has the common information of the Internet of Things resources; for example, when the RFID tag is used to identify the item, the result of the CRR query may be the item manufacturer's The name or URL of the information server. For an IRR query, the resource identification server may need to undergo multiple recursions, and the final returned result will be the interactive communication address or resource attribute information corresponding to a single IoT resource, and the corresponding resource returned in the middle is the recursive query. Identifies the URL of the server.

基于上述，如果终端设备进行的是 CRR查询，则步骤 104中的物联网资源的第一信息即为最终查询结果。如果终端设备进行的是 IRR查询，则步骤 104中的物联网资源的第一信息为中间结果，可以是资源标识管理*** 的第二地址信息。其中，这里的第二地址信息是指资源标识管理***上存储 IRR查询过程中的中间结果的地址。第二地址信息可能与第一地址信息相同，也肯能不同。举例说明，对于分层结构的资源标识管理***，第二地址信息可以是其中某个第一级资源标识服务器的地址，也肯能是某个第二级资源标识服务器的地址。 Based on the above, if the terminal device performs a CRR query, the first information of the Internet of Things resource in step 104 is the final query result. If the terminal device performs an IRR query, the first information of the Internet of Things resource in step 104 is an intermediate result, which may be the second address information of the resource identifier management system. The second address information herein refers to the address of the intermediate result stored in the IRR query process on the resource identifier management system. The second address information may be the same as the first address information, and may be different. For example, for the hierarchical resource identification management system, the second address information may be the address of one of the first-level resource identification servers, and may also be the address of a second-level resource identification server.

如果步骤 104中的物联网资源的第一信息是资源标识管理***的第二地址信息，则终端设备还可以进一步根据物联网资源的第一信息（即资源标识管理***的第二地址信息）向资源标识管理***发送第三查询请求，接收资源标识管理***根据第三查询请求进行查询返回物联网资源的第二信息。其中，第三查询请求包括资源标识。 If the first information of the IoT resource in the step 104 is the second address information of the resource identifier management system, the terminal device may further further generate, according to the first information of the Internet of Things resource (ie, the second address information of the resource identifier management system) The resource identifier management system sends a third query request, and the receiving resource identifier management system performs the query to return the second information of the Internet of Things resource according to the third query request. The third query request includes a resource identifier.

在此说明，物联网资源的第二信息可能是最终查询结果，也可能是中间结果。如果物联网资源的第二信息是中间结果，则终端设备可以进一步根据物联网资源的第二信息向资源标识管理***发送查询请求，即不断执行递归查询，直到获取到最终结果为止。 Here, the second information of the IoT resource may be the final query result or the intermediate result. If the second information of the Internet of Things resource is an intermediate result, the terminal device may further send a query request to the resource identification management system according to the second information of the Internet of Things resource, that is, continuously perform the recursive query until the final result is obtained.

Narration.

下面以物联网资源为 RFID标签为例，详细说明本发明技术方案的实施过程。 The following describes the implementation process of the technical solution of the present invention by taking an IoT resource as an RFID tag as an example.

首先做如下假设：假设生产厂商 A是一个家具生产厂商，釆用 RFID 标签标识其所生产的家具产品 , RFID标签的编码格式釆用 EPC编码方案。对 RFID标签的 EPC编码方案已经预先在 "epc.rfid.com"对应的标准标识服务器中进行了注册。生产厂商 A将家具所对应的详细信息存储在其管理的信息服务器 C中，且信息服务器 C与该批次家具的映射信息已经预先在 "epc.rfid.tnsroot.cn" 对应的资源标识服务器中。设用户 B是一个购买了生产厂商 A生产的智能家具的用户，并在其智能手机上安装了相关的物联网终端应用，用户可通过该应用查询家具信息。具体查询过程如下： First make the following assumptions: Assume that manufacturer A is a furniture manufacturer, using RFID The label identifies the furniture product it produces, and the encoding format of the RFID tag uses the EPC encoding scheme. The EPC encoding scheme for RFID tags has been previously registered in the standard identification server corresponding to "epc.rfid.com". Manufacturer A stores the detailed information corresponding to the furniture in its managed information server C, and the mapping information of the information server C and the batch of furniture has been previously in the resource identification server corresponding to "epc.rfid.tnsroot.cn". . User B is a user who purchased the smart furniture produced by manufacturer A, and installed the related IoT terminal application on his smart phone, through which the user can query the furniture information. The specific query process is as follows:

第一步：用户 B利用智能手机的近场通信（ Near Field Communication, NFC ) 等接口读取 RFID标签，获取家具对应的 16位标准标识 Step 1: User B uses the interface of the Near Field Communication (NFC) of the smartphone to read the RFID tag and obtain the 16-bit standard identifier corresponding to the furniture.

"0101010000010101 " 和 64位资源标识： "0101010000010101" and 64-bit resource identifier:

010" 。其中，标准标识和资源标识是以二进制形式表示的。 010". The standard identifier and resource identifier are represented in binary form.

第二步：查询家具信息的智能手机调用其中的解析器，将标准标识和资源标识发送给解析器。 Step 2: The smartphone that queries the furniture information calls the parser, and sends the standard ID and resource ID to the parser.

第三步：解析器利用标准标识的信息选择并添加资源类型和国家 /地区顶级域名的后缀，映射为对应的标准标识服务器的 URI_S , 4 设该 URI_S为 "21.84.rfid.com" 。 Step 3: The parser uses the information of the standard identifier to select and add the suffix of the resource type and the country top-level domain name, and maps to the URI _S of the corresponding standard identifier server, and sets the URI _S to "21.84.rfid.com".

第四步：解析器利用 URI_S向标准标识管理***发送查询请求，并接收标准标识管理***中 "epc.rfid.com"对应的标准标识月良务器最后返回的标准标识对应的命名规则 X。 The fourth step: the parser uses the URI _S to send a query request to the standard identification management system, and receives the naming rule X corresponding to the standard identifier returned by the standard identifier of the "epc.rfid.com" in the standard identification management system. .

该过程具体可见步骤 103的实施方式的描述。 This process is specifically seen in the description of the embodiment of step 103.

第五步：解析器利用命名规则 X将资源标识映射为对应的资源标识服务器的 URI_R, 假设该 URI_R为： "2730.43301.21674.epc.rfid.com" 。 Step 5: The parser uses the naming rule X to map the resource identifier to the URI _R of the corresponding resource identifier server, assuming that the URI _R is: "2730.43301.21674.epc.rfid.com".

第六步：解析器利用 URI_R向对应的资源标识管理***发送查询请求，并最终接收资源标识***中 "epc.rfid.tnsroot.cn" 对应的资源标识服务器返回的资源标识所标识的物联网资源的第一信息，假设该第一信息为：Step 6: The parser uses the URI _R to send a query request to the corresponding resource identification management system, and finally receives the Internet of Things identified by the resource identifier returned by the resource identification server corresponding to the "epc.rfid.tnsroot.cn" in the resource identification system. The first information of the resource, assuming that the first information is:

"http:// Furniture2012011800123.epc.rfid.tnsroot.cn" 。该第一信息即为访问信息服务器 C所需的地址。 "http:// Furniture2012011800123.epc.rfid.tnsroot.cn". This first information is the address required to access the information server C.

该过程具体可参见步骤 104的实施方式的描述。 This process can be seen in detail in the description of the embodiment of step 104.

第七步：智能手机（更为具体的是智能手机中的物联网终端应用）通过解析器获取的第一信息与信息服务器 c发起通信，获取家具的详细信息并最终反馈给用户 B。 Step 7: Smartphone (more specifically, IoT terminal application in smartphone) The first information acquired by the parser initiates communication with the information server c to obtain detailed information of the furniture and finally feed back to the user B.
