Dual authentication door lock

Abstract

The invention discloses a dual authentication door lock. The dual authentication door lock comprises a fingerprint key, a checking module, and a locking mechanism; the locking mechanism comprises a side spring bolt, an upper spring bolt and a lower spring bolt; through an electric push rod, popping and retraction of the spring bolts can be controlled through an electric push rod, the checking module is used for determining the identity of a guest and comprises a lock cylinder and a processing module, after the lock cylinder rotates by a certain angle, an interface of the processing module canbe exposed out, the key can be inserted into the processing module only by rotating a dynamic angle, in the process, a radio frequency identification module verifies an electronic label in the key, first-layer verification is obtained, after the key is inserted in the processing module, the fingerprint identifying part in the key is powered on, the fingerprint identifying part sends the information after fingerprint identifying to the processing module, second-layer verification is achieved, unlocking is achieved only through two-time verification, and safety is greatly improved.

Description

technical field [0001] The invention belongs to the field of locks, and in particular relates to a double authentication door lock. Background technique [0002] The lock cylinder can be divided into three levels: a, b, and c according to its protection level, representing different security levels from low to high. However, in addition to key unlocking, the current door locks, fingerprints, passwords and other unlocking methods also tend to replace traditional key locks. , but these methods can only be verified from one of the identity features, so it is still easy to be counterfeited, and the unlocking time of the password door lock is longer than that of the fingerprint door lock, but the fingerprint reader fixed on the door is easy to be illegal Molecular damage, and most of the identification modules of this kind of door lock need to work for a long time, so the battery needs to be replaced frequently. Contents of the invention [0003] In view of the deficiencies in...
