Finger vein recognition access control device with lock cylinder

Abstract

Provided is a finger-vein recognition access control having new type of lock cylinder, comprising a blocking piece (1), a spring (2), an attracting block (3), contact pins (9), a recognition device (4), a microprocessor (6), a drive motor (7), a lock cylinder part (8), and a contact pin plate (11); the blocking piece (1) is located on the exterior of the lock cylinder part (8) of a lock structure (5) and is used for blocking the lock cylinder part (8); the contact pin plate (11) is placed directly below the blocking piece (1); the upper part of the contact pin plate (11) is equipped with the spring (2), one or more attracting blocks (3), and two or more contact pins (9), used for controlling the displacement of the blocking piece (1); when a signal recognized by the recognition device (4) is processed by means of the microprocessor (6) and then transmitted to the contact pin plate (11), the blocking piece (1) is attracted by means of the attracting blocks (3); when the contact pin (9) has made full contact with the blocking piece (1), the signal is delivered to the microprocessor (6); the microprocessor delivers the signal to the drive motor (7), and the drive motor (7) controls the lock cylinder part (8) to unlock; of the blocking piece (1) and the attracting blocks (3), one is made of a permanent magnet and the other is made of a ferromagnetic material, or both are constituted by a permanent magnet and their directions of polarity are such that they mutually attract. The present device is highly secure and low-cost, and has a broad range of applications.

Description

technical field [0001] The invention relates to an identifiable door lock, in particular to a finger vein identification access control device with a lock cylinder. Background technique [0002] Smart locks have the advantages of security, convenience, and advanced technology. 1. Security: ①In the general security environment of the community, the general method of opening the door lock handle cannot guarantee the safety performance. It is easy to drill a small hole from the outside of the door and then use the wire to roll the handle to open the door. The recently released smart locks are guaranteed by patented technology. A safety handle button is added to the indoor handle setting. You need to hold down the safety handle button and roll the handle door to open it, bringing a safer use environment. (At the same time, according to the needs of users, this function can be selectively set through simple operations.) ②Ordinary fingerprint combination locks have the risk of pa...
