School library book-borrowing control system based on fingerprint identification

Abstract

The invention provides a school library book-borrowing control system based on fingerprint identification, and belongs to the field of in / out management. The system comprises a fingerprint identification circuit, a touch display screen, a voice circuit, a controller circuit, a motor drive circuit, an outlet switch, an RFID tag induction circuit, an RFID tag induction unlocking circuit, a server, a PC and an RFID tag. The output end of the fingerprint identification circuit is connected with the controller circuit; the touch display screen is connected with the controller circuit; the input end of the voice circuit is connected with the controller circuit; the input end of the motor drive circuit is connected with the controller circuit; the output end of the motor drive circuit is connected with the outlet switch; the input end of the RFID tag induction circuit is connected with the controller circuit; the output end of the RFID tag induction unlocking circuit is connected with the controller circuit; the RFID tag is in wireless connection with the RFID tag induction circuit and the RFID tag induction unlocking circuit; and the RFID tag is pasted on each book.

Description

technical field [0001] The invention relates to the field of entry and exit management, in particular to a school library borrowing control system based on fingerprint identification. Background technique [0002] Fingerprint identification refers to identification by comparing the detailed feature points of different fingerprints. Fingerprint recognition technology involves image processing, pattern recognition, computer vision, mathematical morphology, wavelet analysis and many other disciplines. Because everyone's fingerprints are different, even between the ten fingers of the same person, there are obvious differences in fingerprints, so fingerprints can be used for identification. Since the orientation of each printing is not exactly the same, different points of application will cause different degrees of deformation, and there are a large number of fuzzy fingerprints. How to correctly extract features and achieve correct matching is the key to fingerprint recognition...

AI Technical Summary

Problems solved by technology

However, whether it is manual registration of borrowing books or scanning QR codes for borrowing books, special personnel are required to be on duty at the borrowing office, which requires fixed human resources for management.

Therefore, the manpower and material resources of phone calls are relatively large. With the development of electronic technology, it is necessary to design a system that can automatically continue to borrow books.
