Intelligent fingerprint coded lock

Abstract

The invention discloses an intelligent fingerprint coded lock which comprises an electric control lock, a single-chip microcomputer module, an outdoor password input module, an indoor password input module, a fingerprint module and a power module, wherein the single-chip microcomputer module is connected with the electric control lock, the outdoor password input module, the indoor password input module and the fingerprint module; the power module supplies power to the electric control lock, the single-chip microcomputer module, the outdoor password input module, the indoor password input module and the fingerprint module. Compared with a conventional electronic coded lock, the intelligent fingerprint coded lock has the advantage that an outdoor single screen is high in operation safety. The outdoor password input module is used for opening a door, and the indoor password input module is used for realizing adding, modification, deletion, setting and displaying, and can be used for setting a password with other numbers and setting that the lock cannot be opened until a fingerprint and the password are used together. The intelligent fingerprint coded lock further has a creative user management function, including authority levels such as visitors, children, adults, the house owner and the manager, so that the safety of the lock is further improved, and the design is more humanized.

Description

technical field [0001] The invention belongs to the technical field of intelligent locks, and relates to an intelligent fingerprint password lock. Background technique [0002] Fingerprint lock is a kind of intelligent lock with human fingerprint as identification carrier and means. It is the perfect crystallization of computer information technology, electronic technology and mechanical technology. The uniqueness and non-replicability of fingerprints determine that fingerprint locks are the safest locks among all locks at present. The intelligent fingerprint electronic code lock makes full use of the software and hardware resources of the 51 system single-chip microcomputer, and introduces the intelligent analysis function, which improves the reliability and security of the system. However, the current smart fingerprint electronic code locks on the market are basically single-sided outdoor operations. When adding and changing the password outside the door, it may be peeped...

AI Technical Summary

Problems solved by technology

However, the smart fingerprint electronic combination locks currently on the market are basically operated on one side outdoors, and outsiders may be peeped when adding and changing passwords outside the door, and they are not humanized enough, so users are not satisfied.
