Intelligent book storing and taking device and method

Abstract

The invention provides an intelligent book storing and taking device and method, and the intelligent book storing and taking device comprises a bookshelf and a controller; the bookshelf comprises one or more shelves, and the controller comprises a plurality of frequency modulation antennas, a multiplexer and a read-write module; the frequency modulation antenna is arranged in the one or more shelves, is controlled to switch working frequency points among different frequency points on the same working frequency band, and is used for transmitting a read-write signal to the corresponding shelf and receiving a corresponding response signal; the multiplexer is controlled to pass through the read-write signal and the response signal in a time division duplex mode; and the read-write module is used for controlling the multiplexer to pass through the read-write signals of the different frequency points in different time slots in a polling manner, synchronously controlling the frequency modulation antenna to be switched to the corresponding frequency point so as to transmit the corresponding read-write signal, and analyzing the response signal into label data to be output. When the radio frequency tag offsets frequency, read-write signals of different frequency points are transmitted through polling, and the problem of frequency offset of the radio frequency tag is solved.

Description

Technical field[0001]The present invention relates to the field of radio frequency technology, and more particularly to a smart book access device and a smart book access method.Background technique[0002]At present, RF technology is widely used in library book management. In general, in order to intelligently manage books, it is easy to find, positioning, and inventive, the radio frequency label is pasted in the book, and the reading and writing of the reading and writing apparatus on the bookshelf are radiated by radio frequency tags to pass the radio frequency. The label feedback label data acquires book information on the bookshelf, with easy intelligent management library per books per books.[0003]In practice, when the book is thinner and a large number of stacked on the same layer of the bookshelf, the radio frequency label distance within a large number of books is too short, so that the radio frequency tag is interfere with each other, causing the frequency point of certain r...

AI Technical Summary

Problems solved by technology

[0003] In practice, when the books are thin and stacked on the same layer of the bookshelf, the distance between the radio frequency tags in a large number of books is too short, causing mutual interference between the radio frequency tags and causing the frequency points of some radio frequency tags to shift

The smart bookshelf in the prior art only transmits radio frequency signals corresponding to the frequency points of the unbiased RF tags, so the smart bookshelf only obtains the book information fed back by the unbiased RF tags, while the frequency-biased RF tags correspond to Book information cannot be obtained, therefore, some books will not be able to be searched and located, making the intelligent management of books technically difficult
