Embodiment 1

[0102] refer to figure 1 , figure 2 , image 3 with Figure 4 As shown, a self-service book borrowing and returning device for anti-theft includes an upper device 1, a book placing platform 2 and a lower device 3; wherein: the upper device 1 is used to transmit and detect books, and the book placing platform 2 is used For placing books, the lower device 3 is used for detection and control; the upper device 1 and the lower device 3 are connected through the book placing platform 2 .

[0103] In the above scheme, the upper device 1 is used to transmit and detect books, the book placing platform 2 is used to place books, and the lower device 3 is used to detect books and control the entire device. By collecting images of books, the automatic detection and recognition of books is realized. To prevent "stealing the beam and changing the pillar" type of book theft.

[0104] Preferably, the upper device 1 includes a book bin 11, a magnetic flux detection device 12, a processing ...

Embodiment 2

[0137] As shown in the picture Figure 5 , Image 6 with Figure 7 As shown, a method for self-service borrowing and returning of books for anti-theft, the steps of borrowing books include:

[0138] S1-1 Detect and read the unique identification barcode of the book. If the barcode cannot be read, it will prompt "Please put the book in the correct way according to the requirements" to end the book borrowing process; otherwise, go to the next step.

[0139] S1-2 Retrieve the in-library status of the book with the barcode. If the status is not "in-library", it will prompt "only in-library books can be borrowed", and end the book borrowing process; otherwise, go to the next step.

[0140] S1-3 Retrieve whether the book has magnetic flux, if not, prompt "abnormal magnetic flux, please go to manual service", end the book borrowing process; otherwise, go to the next step.

[0141] S1-4 Collect the cover image, book top image, and forefoot image of the book, and calculate the forma...

Embodiment 3

[0171] refer to figure 1 , figure 2 , image 3 with Figure 4 As shown, when borrowing a book, the reader selects a book to borrow on the display screen, reads the library card information, and the display screen 151 will display the current number of books that can be borrowed, and the book cover is down, the spine is to the left, and the top of the book is on the top. The previous way of loading books.

[0172] The reader puts the pre-borrowed books into the book bin 11 from the entrance of the book bin, and is installed on the top surface of the book bin 11. After the position detector 111 in the middle of the left and right, and about 2 / 3 of the distance from the front side of the book bin senses the book, it passes through the center. The processor 33 sends a signal to the book throughput longitudinal auxiliary device group 1122, the stepping motor 43 is started, and the DC motor 41 and the rubber wheel 42 are driven down through the internally threaded sleeve 45. Whe...

Abstract

The present invention relates to a self-service borrowing and returning device for books for anti-theft, which includes an upper device, a book placing platform and a lower device; wherein: the upper device is used to transmit and detect books, the book placing platform is used to place books, and the The lower device is used for detecting and controlling the device; the upper device and the lower device are connected through the book placing platform. The present invention provides a device and method for self-service borrowing and returning of books for anti-theft. By recognizing the image of the top and edge of the book, the judgment of stacking and clamping of multiple books is performed, and the thickness of the book is assisted. The accuracy of judging a book is higher than the existing scheme based on the physical characteristics of the book. It realizes the detection and judgment of a book, and realizes the unattended self-service borrowing and returning operation for books with barcode identification and magnetic stripe anti-theft. There is no need for additional book processing and pre-collection of book physical feature data and images, effectively preventing book theft.

Description

technical field [0001] The invention relates to the fields of anti-theft and barcode identification devices, in particular to a device and method for self-checking books for anti-theft. Background technique [0002] Because of its low cost and ease of use, magnetic strips are still widely used by most libraries to prevent book theft. With the popularization and dailyization of national reading, the number of books borrowed and returned by libraries is increasing. In order to improve borrowing and returning efficiency and reduce labor costs, some libraries have begun to transform from a manual borrowing and returning model to a self-service borrowing and returning model. There are already many proposals for self-service and automatic book borrowing and returning methods, equipment and systems. The core of evaluating the pros and cons of a book self-service borrowing and returning program is that it can effectively prevent various book theft while supporting automatic book b...
