Thing information traceability system and method with relevance perception

Abstract

The invention discloses a thing information traceability system and method with relevance perception. According to the method, an information server receives RFID original data processed by middleware through a capturing interface; in combination with logical processing, RFID data are formed and stored in an information database; RFID mapping data are disseminated on a discovery server through a registration interface; sharing inquiry of the RFID data is open toward application through an inquiry interface; dissemination of the RFID mapping data of the information server is received by the discovery server through the registration interface; through relevance analysis, the RFID mapping data are stored in a mapping database; RFID mapping data sharing among different discovery servers is provided through a communication interface; inquiry of the RFID mapping data is open toward the application through the inquiry interface. On the basis that due to changes of combination, or splitting and other inclusion relations among things, the RFID data generate a dynamic state correlation, completeness of a traceability inquiry result is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and in particular relates to an article information traceability system and method with correlation perception. Background technique [0002] The International Organization for Standardization GS1 has given a clear definition of traceability, that is, whether the history, location and other application conditions of an item can be queried and verified through identification records. It can be seen that the core issues that traceability services are most concerned about include two points, that is, how to identify an item and how to find the corresponding identification record data. [0003] Radio-frequency identification technology (Radio-frequency identification, RFID) is such an automatic identification and data collection technology without direct contact, which can be used to track and locate target objects. Its main features are: [0004] 1) For the unique identification problem:...

AI Technical Summary

Problems solved by technology

However, the existing schemes generally lack the consideration of the correlation between RFID data, which leads to the impact on the traceability service quality (integrity)

The disadvantage of the existing schemes is that they do not pay enough attention to the inclusive correlation between RFID data, and only use the inclusive correlation as a basis for RFID data compression, but do not consider the analysis of inclusive correlation in the process of traceability.

Then only querying the item information data associated with the identification SGTIN1 cannot solve this actual demand
