Embodiment Construction

[0013] In order to facilitate the understanding and implementation of the present invention by those of ordinary skill in the art, the present invention will be further described in detail with reference to 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 , The present invention provides a unique collision set-based radio frequency tag monitoring method. The system is based on a reader and N tags. These tags have been identified in the previous identification process, and their numbers are 0 to N. -1, and the reader / writer 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 according to the ...

Abstract

The invention discloses a radio frequency tag monitoring method based on a unique collision set, a system based on the method comprises a reader-writer and N tags, the numbers of the tags are 0 to N-1respectively, and the reader-writer records the association between the number of the tag and the ID information. The method comprises the following steps of firstly, generating the unique collision set of the RFID tag, and then setting a reader-writer identification tag method. Experiments show that when the tag ID is 96 bits, 3.7 tags can be identified in one time slot, and the identification efficiency is superior to that of other tag identification algorithms.

Description

Technical field [0001] The invention belongs to the technical field of radio frequency identification, and specifically relates to a radio frequency tag monitoring method based on a unique collision set. Background technique [0002] In many fields such as public safety, logistics, and transportation control, the continuous monitoring of objects is a very important issue. For example, monitoring goods in factories and books in libraries. 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. Attach the tag to the object, and the identification information of the object can be read by means of wireless communication through the reader. Traditional tag monitoring methods cannot use empty time slots and collision ti...
