Description

TECHNICAL FIELD

[0001] The present application relates to the field of intelligent lock, and particularly to a new type of fingerprint and finger vein intelligent lock. BACKGROUND

[0002] The fingerprint identification authentication device is integrated on the handle or door handle of the intelligent door lock. When holding the handle or door handle, the thumb is just placed on the collection window of the fingerprint identification authentication device. After successful identification, the door can be quickly opened. The whole door opening action is completed at one time. This door opening method is usually promoted as one-handed opening of the intelligent door lock. At present, the one-handed opening method has been quite popular in the intelligent door lock industry. The public is also very familiar with the fingerprint one-handed opening method. Generally, the intelligent door lock is equipped with an anti-hijacking function. After entering the fingerprint or password with the anti-hijacking alarm function, when hijacked, the door can be opened by using the anti-hijacking fingerprint or password. After opening the door, an alarm information will be sent to the preset alarm object of the user. However, due to the design of the one-handed opening intelligent lock, the thumb fingerprint cannot be set as the anti-hijacking fingerprint. When other fingers are set as the anti-hijacking fingerprint, the hijacker will be alerted when he finds that the user opens the door in an abnormal way, which will bring danger to the user's life.
