Embodiment Construction

[0030] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] 1. RFID data processing four-layer architecture

[0032] The invention divides the RFID data processing process into four levels, and each level completes a different processing process. RFID data

[0033] Process the four-level topology diagram as attached figure 1 shown.

[0034]The physical reader layer is the actual reader-writer. In practical applications, several readers are often placed in the same area according to the application needs to complete the reading of the tag at a certain position, so as to reduce the interference of the reader-writer. The negative reading of the tag ensures the correctness of the reader to read the tag. Therefore, a collection of multiple readers with the same function is formed. In practical applications, the user does not care which one reads the tag information, but only cares about the reading of the tag by the col...

Abstract

The invention is an RFID system dynamic tag information collection and processing scheme and relates to a method of reducing the negative reading, eliminating the positive reading and filtering out the redundant reading of original tag data flows. The invention discloses a four-layer RFID data processing structure which comprises a physical reader-writer layer, a logic reader-writer layer, a relevance reader-writer layer and a convergence layer. The invention also discloses an algorithm for eliminating the positive reading and filtering out the redundant reading, and the algorithm solves the problem of negative reading misjudgement in traditional algorithms through four memory data tables and four judging mechanisms and by designing a positive reading judging module and a positive reading verifying module. The RFID data processing structure and algorithm has certain usage value.

Description

technical field [0001] The invention relates to the technical field of application software development and integration, in particular to an RFID dynamic tag data processing framework and method. Background technique [0002] Radio Frequency Identification (RFID) technology is a non-contact automatic identification technology implemented by radio frequency communication technology, which uses radio waves to transmit data between readers and labeled objects. The basic front-end system of RFID generally consists of three parts: tag, receiver and antenna. In recent years, with the development of technologies such as large-scale integrated circuits, radio frequency communications, and information security, RFID has been widely used in public information service industries such as logistics, manufacturing, transportation, medical care, anti-counterfeiting, tracking, equipment, and asset management. Due to its characteristics of high-speed moving object recognition, multi-target ...
