Intelligent fingerprint combination lock

Abstract

The invention discloses an intelligent fingerprint combination lock, which comprises a functional display screen, a digital combination keyboard, a magnetic card sensing unit, a lock core, a covering plate, a handle, a fingerprint image acquisition sensing unit, an A / D conversion unit, an infrared sensor, a memory, Power supply unit, single chip microcomputer, recognizer, sound and light alarm unit, direct drive motor mechanism and door opening execution unit. The present invention is equipped with an optical fingerprint image acquisition unit, which can quickly pass through the surface of the finger and the dead skin layer to reach the living body of the finger skin, directly read the fingerprint cluster, and effectively improve the safety of the system; the direct drive motor mechanism is provided High-speed operation can effectively avoid failures caused by friction loss during unlocking, effectively prevent interference, and have a long service life; the 360° idling lock cylinder has anti-theft and anti-violence functions, which greatly improves the safety of use; there is a password , fingerprint, password plus fingerprint, card swiping, mechanical unlocking and other multiple unlocking methods.

Description

technical field [0001] The invention relates to a combination lock, in particular to an intelligent fingerprint combination lock, belonging to the technical field of security equipment applications. Background technique [0002] Lock is a necessity of life, and it is a representative of making families and companies safe. Locks are usually used in conjunction with doors. The traditional lock is a mechanical lock, which is easy to be picked open and has poor safety performance. For companies, multiple locks are usually used in multiple doors, resulting in a large number of keys, which are easy to be confused and lost. Once the keys are lost, it will cause various cumbersome and complicated problems, resulting in physical and mental fatigue; there are some fingerprints on the existing market. Combination lock, this kind of combination lock is expensive, and the lock cylinder is easy to pry open, and the security performance is weak. At the same time, frequent unlocking will ca...

[0002] Lock is a necessity of life, and it is a representative of making families and companies safe. Locks are usually used in conjunction with doors. The traditional lock is a mechanical lock, which is easy to be picked open and has poor safety performance. For companies, multiple locks are usually used in multiple doors, resulting in a large number of keys, which are easy to be confused and lost. Once the keys are lost, it will cause various cumbersome and complicated problems, resulting in physical and mental fatigue; there are some fingerprints on the existing market. Combination lock, this kind of combination lock is expensive, and the lock cylinder is easy to pry open, and the security performance is weak. At the same time, frequent unlocking will cause friction loss and various failure problems, and it is easy to cause internal interference, resulting in a high failure rate of the lock. The service life is low, therefore, an intelligent fingerprint combination lock is proposed for the above problems
