LIBRARY BOOK RESERVATION METHOD BASED ON ULTRAHIGH-FREQUENCY RFID TECHNOLOGY

摘要

Disclosed is a library book reservation method based on an ultrahigh-frequency RFID technology, comprising the steps of: step 1, reading an RFID tag attached to each book using an RFID reading device, wherein information read by the RFID reading device corresponding to each group of books comprises: ID information id about a tag, a phase difference θ for collecting the current tag and a time t for collecting the current tag, and the information read by the RFID reading device corresponding to each group of books is represented by a triple Tag = id, t, θ; step 2, pre-processing the information in the triple Tag; and step 3, acquiring a change rule of book phases, establishing a model, and analyzing a location relationship between RFID antennas and books to rank the books. In the present invention, additionally read books of other layers in the stocktaking process are eliminated using radio frequency phases first, and then, books of this layer are ranked, so that the location where each book is located can be accurately positioned, so as to facilitate borrowers.
