Intelligent multifunctional door lock, control system and control method

Abstract

The invention provides an intelligent multifunctional door lock, a control system and a control method, and relates to the field of locks. The intelligent multifunctional door lock is characterized in that the door lock comprises a lock box and a panel, a lock cylinder and a handle are arranged on the lock box, an operation panel with a fingerprint sensor is arranged on the panel, a sliding cover can vertically and slidably open and close and covers the panel, sliders are mounted on two sides of the fingerprint sensor and can vertically slide, guide grooves are formed in the sliders, fingerprint brushes are mounted in the guide grooves in the left slider and the right slider and paste and cover the surfaces of fingerprint identifiers, a power device is arranged in the panel and drives the fingerprint brushes to wipe backwards and forwards on the surfaces of the fingerprint identifiers through the sliders, fingerprints remaining on the surfaces of the fingerprint identifiers are completely cleaned, and a camera is arranged on the sliding cover.

Description

technical field [0001] The invention relates to the field of locks, in particular to an intelligent multifunctional door lock, a control system and a control method. Background technique [0002] Fingerprint recognition technology is currently the most widely used and mature biometric technology in the field of biometrics. According to different fingerprint collection methods, fingerprint collection modules are divided into optical type, semiconductor capacitive type, and radio frequency type; when used in the security field, the latter two collection methods have a higher security level, but have higher requirements for fingers. Fingers, dry fingers, wet fingers, shallow texture fingerprints, and elderly finger users may have defects that are difficult to identify; optical acquisition methods can be applied to relatively harsh environments, and there are no strict requirements for fingers, but traditional designs will use Fingerprint identification window, on this piece of...

Problems solved by technology

According to different fingerprint collection methods, fingerprint collection modules are divided into optical type, semiconductor capacitive type, and radio frequency type; when used in the security field, the latter two collection methods have a higher security level, but have higher requirements for fingers. Fingers, dry fingers, wet fingers, shallow texture fingerprints, and elderly finger users may have defects that are difficult to identify; optical acquisition methods can be applied to relatively harsh environments, and there are no strict requirements for fingers, but traditional designs will use The fingerprint identification window, on this glass sheet, often leaves the user's fingerprints. By irradiating these fingerprints with a flashlight, or extracting fingerprints and copying them, fake fingerprints can be obtained, and then these residual fingerprints or fake fingerprints can be used for identity information. The forgery of biometrics becomes exploitable and reduces the security of biometrics
