Embodiment Construction

[0013] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0014] please see figure 1 , a radio frequency tag monitoring method based on a unique collision set provided by the present invention, based on a system of a reader and N tags, these tags have been identified in the previous identification process, and their numbers are 0 to N respectively -1, and the reader records the association between the tag number and ID information;

[0015] The method includes the following steps:

[0016] Step 1: Generate a unique collision set of RFID tags;

[0017] The reader divides all tags into several independent sets acco...

Abstract

The invention discloses a method for monitoring radio frequency tags based on a unique collision set. The system is based on a reader and N tags, the tags are numbered from 0 to N-1 respectively, and the reader records the number and number of tags and N tags. The association between ID information; the invention first generates a unique collision set of RFID tags, and then sets a method for the reader to identify the tags; through experiments, when the tag ID is 96 bits, the invention can identify 3.7 tags in one time slot , the recognition efficiency is better than other label recognition algorithms.

Description

technical field [0001] The invention belongs to the technical field of radio frequency identification, and in particular relates to a radio frequency tag monitoring method based on a unique collision set. Background technique [0002] Continuous monitoring of objects is a very important problem in many fields such as public safety, logistics, transportation control and so on. Examples include monitoring goods in a factory and books in a library. The emerging radio frequency identification technology (RFID, Radio Frequency Identification) is very suitable for solving this problem. The RFID system includes tags and readers, and has the advantages of wireless communication, long communication distance, small size, large storage capacity, and fast transmission speed. By attaching the tag to the object, the identification information of the item can be read by means of wireless communication through the reader. Traditional tag monitoring methods cannot take advantage of empty ...
