Intelligent door lock non-inductive door-opening system based on face recognition and control method thereof

Abstract

The invention discloses an intelligent door lock non-inductive door-opening system based on face recognition, which comprises a detection module for detecting a movement track of a user and judging amovement direction of the user, a control module for activating the operation of an identification module according to the signal output by the detection module, an identification module for acquiringthe facial feature information of a user and comparing with preset data. When the system works, the detection module acquires whether a user exists in a monitoring range in real time, and collects the movement track of the user and judges the movement direction of the user. When the movement direction of the user is the door opening direction, the identification module is activated under the control of a control module, a user face image is acquired, the acquired face image is compared with preset authorized image information, and a door opening command output by the control module is executed by the intelligent door lock when the acquired face image is identical to the preset authorized image information, thereby achieving the opening of the door. As the system is advanced in predictingthe door opening of the user, sufficient time is provided for the system reaction, the time delay starting or stopping are avoided when the user is detected, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of smart locks, in particular to a face recognition-based smart door lock non-inductive door opening system and a control method. Background technique [0002] The existing authentication methods for access control unlocking mainly include card swiping, fingerprint, and face recognition. After the comparison is successful, the microprocessor issues an opening command, and the door lock is opened through an electromagnet or a motor, allowing people to open the door and enter smoothly. [0003] Under the current technical conditions, there are two obvious technical disadvantages when using these authentications to unlock: the first is the need for contact comparison. The second is that the system needs to be activated when the user is near the access control, and it needs to wait for 3-5 seconds before unlocking, which results in poor user experience. Contents of the invention [0004] The technical problem...

Problems solved by technology

[0003] Under the current technical conditions, using these certifications to unlock the lock, there are two obvious technical shortcomings: one is the need for contact comparison

The second is that the system needs to be activated when the user is near the access control, and it needs to wait for 3-5 seconds before unlocking. The user experience is poor.
