1. Identification analysis process
With the development of the industrial Internet, the identification object has been extended from the previous domain name to a more specific and broad object such as a product, a component, a transaction, and a service.
The identification of the industrial Internet can be regarded as the "identity card" of items, intelligent manufacturing equipment or objects of the Internet of things. The identification analysis is used to realize the cross-region, cross-industry, and cross-enterprise mapping from identification to address of the object in the entire industrial Internet system, and then realize functions such as positioning and information query. Therefore, the identification solves the problem of "who am I", the identification resolution solves the problem of "where am I", and the result of the analysis informs the other party "what can I do" .
2. Industrial Internet logo analysis system
The identification analysis system of the Industrial Internet includes five levels: root node, national top-level node, second-level node, enterprise node and public recursive node.
1) The secondary node is a node that provides logo registration and analysis services for the industry (generally built by leading enterprises or large third-party organizations). It has the characteristics of high efficiency, high stability, safety and reliability, and can connect heterogeneous logo systems. The information positioning and resource sharing of the industrial Internet platform provide support, and realize functions such as information filing, monitoring, and certification.
2) An enterprise node is a node that provides logo registration and resolution services based on the actual internal needs of a specific enterprise.
3) The second-level nodes connect upwards with the top-level nodes of the country, and assign identification codes to enterprise nodes downwards and provide services such as identification registration, identification data, and identification analysis.
Formulate standards and specifications such as industrial Internet logo coding specifications, industrial Internet logo analysis secondary node interface specifications, and industrial Internet logo data models that meet the actual needs of an industry, and form unified interface specifications, data formats and other technical requirements, so as to realize data interconnection, interoperability, Information Sharing.
(1) Handle identification analysis system
The Handle system has built several root nodes around the world, and each root node is connected to each other to identify and transmit data information. In the Handle system, its encoding rules adopt a hierarchical identification design. Each Handle identification code is a string of variable length in the form of prefix/suffix. The prefix indicates the naming authority and the suffix indicates the local name. In addition, users have partial coding rights, and can independently define coding rules in certain fields, so as to realize the functions and requirements they need.
The Handle system adopts a hierarchical resolution mechanism, and its resolution framework consists of a Handle client, a Global Handle Registration Authority (GHR) and a Local Handle Service (LHS). The specific resolution process is shown in Figure 3. The Handle client sends the prefix code to GHR, queries the location information of the LHS to which the naming authority belongs, and then sends the complete identification code to the LHS to query the analysis result. GHR receives the prefix code sent by the Handle client, queries the registration information of the local naming authority, analyzes the prefix code to obtain the LHS location information, and feeds it back to the Handle client. The LHS receives the identification code sent by the Handle client, queries the local data, analyzes the identification code to obtain the corresponding detailed information, and feeds back the analysis result to the Handle client.
(2) OID identification analysis system
The OID system can uniquely identify and name all scopes and any kind of objects. Once an object is given an identity name, the identity name is always valid. The coding rule of OID adopts a tree-like hierarchical method, and the number of layers supports unlimited expansion, and each layer is separated by ".". The OID identification code is also a string of variable length, which is divided into two forms: pure numbers and alphanumeric combinations. Among them, the digital encoding form takes an integer value from 0 to 16000000. This encoding form is similar to machine encoding, and the retrieval speed is fast but it is inconvenient for manual intervention. The alphanumeric encoding form is a string of 1 to 100 characters in length. This encoding form can be interpreted manually, but there is a problem of excessive information, which leads to occupying more data storage space. my country's OID code follows the naming rules of the national standard GB/T 16263.1-2006 "Information Technology ASN.1 Coding Rules Part 1", and the OID code assigned by the registration agency is permanently unique.
The analysis process of the OID system is a step-by-step analysis. The analysis framework includes the OID client, the national OID registration analysis system and the underlying analysis server. The specific analysis process is shown in Figure 4. First, the OID client uploads the identification code to the national OID registration and analysis system. The national OID registration and analysis system finds its corresponding underlying analysis server according to the identification code registration information, and passes the identification code to the underlying analysis server, and then the underlying analysis server resolves the identification. The detailed information of the object is queried by encoding, and then the analysis result is sent back to the OID client through the national OID registration and analysis system. The step-by-step analysis mechanism of the OID system is more flexible than other systems, and can be deployed directly using the existing network foundation, which is efficient Fast and cost-effective.
(3) Ecode identification analysis system
The Ecode system is composed of Ecode encoding, data identification, middleware, analysis system and security mechanism. It can not only uniquely encode and identify objects in the Internet of Things environment, but also be compatible with other identification systems such as Handle and OID. A complete IoT identification system.
The coding rules of the Ecode system adopt a three-segment structure, and the identification code is in pure digital form, which is composed of three-segment codes: version (V), coding system identification (NSI) and main code (MD), and its form is "V code + NSI code +MD code". Among them, the V code indicates the data structure type of the identification code, the NSI code indicates the registration status of the identification code, and the MD code indicates the specific object in the industry or application scenario.
The parsing process of the Ecode system is iterative parsing. The parsing framework is composed of Ecode client, middleware, coding system parsing server, coding data structure parsing server and item code parsing server. There are 3 steps of analysis, and the specific iterative analysis process is shown in Figure 5. The first is the encoding system analysis. The Ecode client sends the identification code to the encoding system analysis server through the middleware, and the latter analyzes the identification and identification domain name and sends it back to the middleware. Then the coded data structure is analyzed, and the middleware sends the identification domain name and the main code to the coded data structure analysis server, which analyzes the main code domain name and sends it back to the middleware. Finally, the item code is analyzed, and the middleware sends the main code domain name to the item code analysis server, which analyzes it to obtain item information and sends the analysis result back to the Ecode client through the middleware.
