Problems solved by technology

And so on, in most typical Internet of Things applications, it is difficult to guarantee the uniqueness of the "visible" (recorded in the system) electronic identification in the process of item circulation from beginning to end
Therefore, if only a single electronic identification (such as the unique electronic identification of a certain part or a package) is used for information exchange, tracking and tracing, then due to logistics operations such as assembly, packing, and disassembly, the identification will be lost during the logistics process. Hidden, so that information tracking and tracing can only obtain the fragment marked by the logo, but not the complete item information

Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0042] The invention provides a system for tracking item information of the Internet of Things and a semantically-based tracking method and a tracing method for item information of the Internet of Things based on the system. Based on the unique identification of items by radio frequency identification (RFID) electronic tags, this method divides the nodes that items flow through into five types: starting point, end point, flow-through node, assembly node, and split node, and uses tag Attributes, node attributes, item attributes, and operational attributes are marked with different semantic tags, and distributed and stored on each node that the item flows through, so that the tracking and tracing process of the item can be o...

Abstract

The invention discloses a semantics-based article information tracking and tracing method for the Internet of things. Tracking of article information from upstream to downstream and tracing of the article information from downstream to upstream of a certain specific article unit in any link of the article distribution are realized by respectively recording a base attribute and a status attribute of an article and a uniquely coded mapping relation of the article among an upstream and downstream relation of the article distribution, access addresses of the article information of upstream and downstream nodes and the upstream and downstream nodes in a corresponding semantic label on each node which the article passes through. The method solves the tracking chain breaking problem caused by hidden label data of the article due to the operation of assembly, package, partition and the like in the article distribution process. By using the method, the upstream node can know the destination of the product at any time and implement accurate product recall in case of a quality accident; and the downstream node can rapidly judge the origin of the article and rapidly trace the responsibility cause in case of the quality accident.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a semantic-based tracking and tracing method for item information of the Internet of Things. Background technique [0002] With the rapid development of information technology, RFID technology, sensor technology and embedded intelligent technology provide the basic "information sensor" for network services, which will greatly digitize the material world and integrate the material flow process in the material world with the virtual The process of information processing in the world is effectively combined. The Internet of Things endows objects with intelligence through various information sensing devices installed on objects, such as RFID devices, infrared sensors, global positioning systems, laser scanners, etc., and connects to the Internet through interfaces to form an item-to-item connection huge network. By assigning a unique electronic identification to ea...
