PDA RFID scanner Smart Library Management System

PDA RFID scanner Smart Library Management System


  1. Project background


For many years, problems such as borrowing and returning books, quick inventory, search, and ordering books in random shelves have been plaguing the management and staff of the library. The library adopts the new RFID technology to change the traditional operation methods such as book borrowing and returning, book inventory and whole shelf, and improve the efficiency and quality of circulation services. In the high-speed information environment, readers also expect to enjoy new services that are convenient, fast, flexible and stylish, and have a good experience through new technologies.


The "barcode + magnetic stripe" self-service borrowing and returning service relieves the shackles of librarians' manual operation of borrowing and returning books to a certain extent, but it still cannot solve the problems of automatic book inventory, self-service borrowing and returning of books, and book area positioning.


RFID technology has the obvious advantages of intelligent, fast, and non-contact data exchange, which can realize self-service borrowing, high-speed inventory, fast search, positioning, shelf ordering, sorting, etc. It provides the possibility for the transformation of circulation business and the establishment of future smart libraries.


  1. Current status and existing problems of traditional library management


With the development of information technology, libraries, especially university libraries, as important distribution centers and transmission hubs of information resources, play a very important role in the information age. At present, the traditional library has gradually been unable to meet the needs of readers, let alone meet the needs of the rapid development of colleges and universities. Traditional libraries mostly use the barcode management model, which makes it difficult to find books, cumbersome procedures for borrowing and returning, difficulties in arranging and arranging shelves, and cumbersome inventory inventory.


The construction of the library project is conducive to improving the resource utilization rate of the library. Using RFID radio frequency identification technology to effectively manage hundreds of thousands of books in the library, knowing the whereabouts of the books, ensuring that the books are not lost, and improving the intelligence of the library , to provide readers with more comprehensive intelligent services, and accelerate the construction of a modern new library with diversified functions and complete functions to meet the new needs of enterprises for book culture.

  1. Project supporting hardware scheme


Book Electronic Tag


Book electronic tag is a passive low-power integrated circuit product with antenna, memory and control system. The basic data of books can be written and read multiple times in the storage chip, which is used for label identification of book materials. At the same time, the traditional way of implementing books through magnetic stripes is changed to anti-theft through the EAS or AFI that comes with the RFID chip. In the circulation of the RFID system, the RFID book label is the first and bottom link. The library is required to provide an RFID book label for each book in the area where the RFID system is implemented. The following is the picture of the RFID book label. Generally, the label is rolled. Package


Label Conversion Workbench


The label conversion workbench includes a device for RFID reading and writing, encoding and an automatic peeling label for distributing labels, a complete mobile system with a monitor, a PC, and a reading and writing device. Realize the seamless conversion of books from barcodes to RFID through simple and convenient combined equipment, identify circulating book materials, and integrate label stripping processing and chip writing into a simple operation process


Convert, write, modify, etc. the labels attached to the book. According to the collection of 10,000 volumes, one machine can be configured to facilitate the processing of books.


RFID label printer


RFID printer is a printing device that can read and write RFID tag (also known as: electronic tag) IC chip data, and at the same time visually print the data content on the label surface.


RFID printer manufacturers design and add RFID read-write modules on the basis of the structure of barcode printers to write data into the RFID label chip and visually print the content on the label. The printing principle is the same as that of a barcode printer, which is thermal and thermal transfer printing. The most common RFID printers currently on the market generally use UHF or HF.


RFID anti-theft safety door (single channel)


The RFID security door is used to detect the books and materials that have not gone through the borrowing procedures, and detect the borrowing and returning status of the books by sensing the electronic tags of the books. If violations are found, an audible and visual alarm will be issued to warn the current behavior. Integrated three-dimensional omnidirectional sensing technology, supports multiple alarm detection modes. In addition to the anti-theft function, it also supports two-way statistics on the number of readers entering and leaving, so that the library can keep track of the number of people entering and leaving the library at any time.


Placed at the entrance and exit, it can detect books that have not passed through normal circulation, and prevent theft. The quantity is configured according to the site situation



RFID self-service borrowing and returning machine


The RFID self-service borrowing and returning machine is a device for borrowing and returning books by identifying the built-in RFID (Radio Frequency Identification Technology) tags of books.


Readers can self-borrow/return open-shelf books in the library through the campus card and WeChat electronic campus card; it supports multiple borrowing and returning at a time, which improves service efficiency in an all-round way.



RFID handheld


The RFID handheld device obtains the information by scanning the code of the RFID book electronic label and analyzing it, and then feeds it back to the user, so that the user can quickly extract the useful information on the label, and then perform operations such as viewing and modifying. It is used for book entry, manual borrowing and returning.


Mobile inventory vehicle


The mobile inventory vehicle uses the book label as the circulation management medium, and uses the first floor of the single-sided single-link bookshelf as the basic management unit to build a digital-based intelligent library environment through shelf labels and layer labels, so as to realize the collection of new books in the library. , Shelf position change, layer change, old book removal and literature inventory, etc., with EPC tag matching and duplicate tag filtering functions;


Shelf label (RFID)


The RFID book shelf label is the book RFID label identification module in the intelligent library system. Through the book label, book shelf and corresponding reader module, the book label information can be read, including the book name, book number, book The type and borrowing status, etc., can be used as the basis for system sorting to facilitate book management. The book shelf labels are generally pasted on the book shelf, which can manage the books on the same shelf in a unified way. It is beautiful and generous through glue treatment, and the wave-absorbing material is added to avoid the influence of the metal shelf on the label.
