Abstract

The application discloses a door lock device based on iris recognition, including: iris sensor, door lock processing module, and height acquisition module; wherein, the iris sensor also includes: including: CCD imaging chip, lens; lens rotation device, lens rotation The device includes: a stepping motor; a frame for installing lenses; a bracket, one side of the frame is rotatably connected to the bracket; a screw nut, the other side of the frame is rotatably connected to the screw nut; a transmission screw, the screw nut is set on the transmission On the lead screw, the transmission lead screw is connected to the stepper motor to be driven by it; the door lock processing module is electrically connected to the height acquisition module and the iris sensor respectively so that the door lock processing module controls the lens in the iris sensor according to the data of the height acquisition module Turn the device. The benefit of the present application is to provide a door lock device based on iris recognition that can intelligently adjust the detection range of the iris sensor according to the user's height.

Description

technical field [0001] The present application relates to an intelligent door lock device, in particular to a door lock device based on iris recognition. Background technique [0002] The iris remains unchanged after the formation of the fetal development stage, which determines the uniqueness of iris characteristics and the uniqueness of identification. Therefore, the iris feature of the eye can be used as the identification object of each person. In order to improve the security of access control, the application of iris recognition to access control unlocking (ie iris lock) is more and more favored. [0003] In the prior art, iris features are often used for unlocking, and the Chinese utility model patent with the application number of 201820625153 discloses an iris lock, which completes the iris identification of people of different heights by forming an oblique angle on the structure. At present, most of the iris locks on the market are similar to the Chinese utility ...
