Abstract
The utility model belongs to a simple intelligent library anti-theft system, which comprises the following components: an electronic tag, a reader, a microcontroller and application program, wherein a bar code of a book is stored in the electronic tag, when the book pasted with the electronic tag enters a work region, the tag sends the bar code number of the book to the reader, the information received by the reader is sent to a host computer after being processed by the microcontroller, and the application program inquires the borrowing state of the book and determines whether to send out warning sound or not according to the book state. The utility model aims at providing the intelligent library anti-theft system which can identify the borrowed books, allows the readers to take the borrowed books into a library to read and is convenient for the readers. Compared with the existing radio frequency anti-theft system, the intelligent library anti-theft system has simple structure and lower cost and is applicable to middle-size and small-size libraries to use.
Description
Technical field
The utility model belongs to antitheft field, library, relates to the burglary-resisting system of library's intelligent anti-theft and human-based management.
Background technology
Library's burglary-resisting system commonly used at present has two kinds: magnetic stripe is antitheft and radio-frequency (RF) identification (RFID) is antitheft.
The magnetic stripe burglary-resisting system is to detect to the alternating magnetic field of the low frequency generation of 20KHz with 10Hz with detecting antenna (emitting antenna and receiving antenna).Detected object is attached to the magnetic stripe on the books.Because whether this system has only discerned detected books is the books in library, so long as the book in library all can cause warning.So when the reader handled borrow formality after, can't again books be brought into the library and read, caused great inconvenience to the reader.
The books that radio-frequency (RF) identification (RFID) burglary-resisting system allows to be in the state of borrowing are brought into library's reading, but the library's burglary-resisting system that comes into operation at home at present is all huger, and cost is also than higher.Just comprised books such as: the RFID management system of shenzhen library and borrowed automatically also, the books location, books are made an inventory and are antitheft etc. all multi-functional.For numerous Medium and Small-sized Libraries, books are automatically borrowed also and function such as location is not essential.In addition, this burglary-resisting system is written to the state of borrowing of books in the radio-frequency (RF) tag, in case the state of borrowing is rewritten, can't guarantee the safety of books.
Summary of the invention
The objective of the invention is under the antitheft situation of assurance books, can help reader to carry the books that are in the state of borrowing and in the shop, read for a kind of easy library intelligent anti-theft system is provided.
To achieve these goals, the invention provides a kind of library's intelligent anti-theft system based on radio-frequency (RF) identification.It is made of following components:
(1) electronic tag, it is made of a passive radio-frequency (RF) transceiver and emitting antenna, be secured on the books, can be in the perform region receive the energy of reader emission, send the bar code number of books simultaneously with the frequency of 13.56MHZ to reader in the mode of inductive coupling;
(2), reader module, it is made of a reader and corresponding receiving antenna, links to each other with microprocessor, reader provides energy by the mode of inductive coupling to transceiver on the one hand, receives the books bar code number of electronic tag transmission on the other hand;
(3), microprocessor module, microprocessor obtains the data that reader receives, and carries out analog to digital converter, filtering, operations such as format conversion, the corresponding interface by it transfers data to main frame then;
(4) application program module, it operates on the main frame, main frame receives books bar code that microprocessor transmits number, the corresponding books of inquiry in database, if these these books are in the state of borrowing, then let pass, if handling, these these books do not borrow formality, just sound by application program, the prompting reader handles and borrows formality;
(5) database module is created a record at each these books, wherein comprises following information: bar code number, and call number, book name is borrowed state, reader's certificate number, reader's name.Take place to borrow when also operating when books, revise and borrow state and information reader.
In sum, the utility model is that the bar code of books number is stored in the electronic tag, when the reader is being with detected books through the perform region is, electronic tag obtains energy and sends books bar code number to reader.Reader is transferred to signal on the MCU microcontroller after receiving bar code number, and signal is by the processing of microcontroller, change into the information that main frame can discern after, be transferred on the main frame by corresponding interface.After application program detected new bar code number, the state of borrowing of the corresponding books of inquiry in the database was if these these books are in the state of borrowing, then let pass, do not borrow formality if these these books are handled, just sound by application program, the prompting reader handles and borrows formality.
The advantage of native system is:
(1), used REID, accurately discern each these books, help reader be with and to borrow books turnover library.
(2), the RI-I02-112a-03 electronic tag of having selected for use TI company to produce, this label is embedded anti-collision algorithm can be discerned 50 books simultaneously, increases work efficiency.
(3) system architecture is simple, and cost is low, and the device of selecting for use meets ISO/IEC 15693-2, ISO/IEC15693-3, and ISO/IEC 18000-3 standard is convenient to apply in numerous Database in Small and Medium Size College Libraries.
(4), system selects the high-frequency signal of 13.56MHZ for use, is difficult for conductively-closed, the accuracy of detection height.
(5), adopt passive electronic tag, label does not transmit outside the perform region, environmental protection.

Embodiment
As shown in Figure 1, system is divided into following ingredient: electronic module tag, reader module, microcontroller, main frame and the application program that works in main frame, electric power system.
Wherein, electronic tag is fixed on book cover inside, and as shown in Figure 2,1 among Fig. 2 is electronic tag, and 2 for treating books to be detected.Before system comes into operation, earlier electronic tag (1) to be carried out initialization, write the bar code of books.When the reader passed through reader's passage with books to be detected (2), the reader among Fig. 2 (3) was powered to electronic tag by inductive coupling, and after electronic tag (1) obtained energy, it was good to send the books bar code that is stored in the label internal memory to reader (3).After reader (3) receives bar code signal, send microcontroller (4) to, microcontroller (4) is handled signal, and is transferred to main frame by corresponding interface.Main frame, is not reported to the police if books are books of having borrowed by the state of data base querying books, if the state of books is not borrowed, sends warning message by application program, and the prompting reader handles and borrows formality.
Reader among Fig. 2 (3) is installed in the exit, library, is connected on the microcontroller (4) by corresponding interface, and microcontroller can be powered to reader.
