Embodiment Construction

[0050] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0051] figure 1 Shown is the item information parsing process completed by the cooperation of the client, the central management server, the domain name system DNS, and the vendor information server. In the Internet of Things, in order to obtain item information, we take the following steps:

[0052] (1) Read item code and code type;

[0053] (2) The item analysis program initiates a query with encoding type to the central management server, obtains the corresponding formalized decoding rule file, and resolves the item encoding into a domain name according to the analysis rules;

[0054] (3) Initiate a query to the computer domain name system DNS, obtain the corresponding address record, and extract the information service

[0055] business address;

[0056] (4) Visit the information service address to obtain the detailed information of t...

Abstract

The invention belongs to the technical field of Internet of Things information systems, particularly relates to a method for resolving a heterogeneous code to acquire object information by using the formalized decoding rule. The method enables object naming service in the Internet of Things to support the resolution of the heterogeneous code in an expansibility manner; the process of an object code being resolved as a domain name is defined by the formal decoding rule and in the XML (Extensive Makeup Language) format; the formal decoding rule is managed in a unified manner and updated by a central server; and a remote object naming service (ONS) program can download the formal decoding rule of the heterogeneous code from the central server, so that decoupling of the resolution program and the resolution rule is realized, and the ONS (Object Naming Service) can support the resolution of various heterogeneous codes in an expansibility manner.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things information systems, and relates to a method for obtaining item information by analyzing heterogeneous codes using formalized decoding rules. Background technique [0002] Object Naming Service (ONS), also known as Object Naming Service, is responsible for resolving the object from the identifier to the address of the server responsible for providing the detailed information of the item. Therefore, in the Internet of Things, the role of ONS is actually to establish a mapping relationship between item codes and information servers. The basic design principle of ONS service is proposed by EPCglobal International Organization. In the standard process of ONS released by EPCglobal, first the ONS client converts the EPC binary code read by the card reader into a URI, then converts the URI into a domain name, and then initiates a query request to the designated ONS server, and finally the cli...
