Intelligent safety lock based on laser identification technology

Abstract

The invention discloses an intelligent safety lock based on laser identification technology. The intelligent safety lock comprises a laser key for transmitting a laser password signal and a lock cylinder for opening the lock, wherein the laser key comprises a laser transmitting module for transmitting a laser signal, a driving module for driving the laser transmitting module to work, a dynamic coding encryption module for encrypting the laser signal and a transmitting lens for collimating the laser signal, and the lock cylinder comprises a receiving lens for receiving the laser signal, a laser detection module for arranging the received laser signal, a signal identification module for identifying the received laser signal, a dynamic coding decryption module for decoding the received laser signal and a mechanical lock cylinder. The intelligent safety lock is simple in structure, capable of improving the safety of the lock, high in security and uneasy to copy.

Description

technical field [0001] The invention relates to an electronic lock, in particular to an intelligent safety lockset based on laser identification technology. Background technique [0002] A lock is a product used to protect personal property, with the purpose of protecting personal property safety and privacy. In the increasingly complex social security environment, locks with good performance and high safety are an important barrier to ensure the safety of life and property. [0003] Existing locks generally include mechanical locks, fingerprint locks and combination locks. Mechanical locks are opened by the cooperation of keys with different tooth shapes and lock cylinders, but the tooth shapes of the keys are easy to be copied, and the keys of mechanical locks are easy to lose. Anyone who picks up the key can easily open the lock, which greatly reduces the security of the lock. Fingerprint locks use the uniqueness of human fingerprints to identify fingerprints through opt...

Problems solved by technology

[0003] Existing locks generally include mechanical locks, fingerprint locks and combination locks. Mechanical locks are opened by the cooperation of keys with different tooth shapes and lock cylinders, but the tooth shapes of the keys are easy to be copied, and the keys of mechanical locks are easy to lose. Anyone who picks up the key can easily open the lock, which greatly reduces the security of the lock. Fingerprint locks use the uniqueness of human fingerprints to identify fingerprints through optical fingerprint recognition systems, but the misjudgment rate of optical fingerprint recognition systems is high. , and every time the fingerprint is used, the user's fingerprint traces will be left on the optical fingerprint recognition system, and these fingerprint traces have the risk of being copied. In addition, many devices for manufacturing fingerprint hand models have appeared on the market. It is not safe enough; and the password of the combination lock is easy to be cracked or stolen, and the security is not high
