Embodiment 1

[0019] Such as figure 1 As shown, a household device based on finger vein recognition in the present invention includes a main door, on which a circuit board with a door lock drive module and a vein recognition terminal are arranged; the vein recognition terminal includes a finger vein interface board, and a finger vein recognition terminal An infrared filter is installed in the vein interface board, an infrared light source circuit with a light sensor is installed on the top of the finger vein interface board, and a CMOS sensor is installed at the bottom of the finger vein interface board. The CMOS sensor sends image information to the MCU controller, and the MCU controller receives the image information. Send to the image processing module, the image processing module extracts the data of the SD card through the authentication module, and sends the authentication information to the MCU controller; the MCU controller accepts the authentication information, starts the door lock...

Abstract

The invention discloses a household appliance based on finger vein recognition. The household appliance comprises a main door, the main door is provided with a circuit board having a door lock drivingmodule and a vein identification terminal, the vein identification terminal comprises a finger vein interface plate, an infrared filter is arranged in the finger vein interface plate, the upper partof the finger vein interface plate is provided with an infrared light source circuit with a light sensor, the bottom of the finger vein interface plate is provided with a CMOS sensor, the CMOS sensorsends image information to an MCU controller, the MCU controller receives the image information and transmits the image information to an image processing module, the image processing module extractsthe data of a SD card through an authentication module and sends the authentication information to the MCU controller, and the MCU controller receives the authentication information and activates a door lock driving module or sends the authentication information to an upper computer. The SD card stores 5 to 10 sets of finger vein information. The infrared light source circuit is a control circuitof a near-infrared light source. The beam of the near-infrared source intersects with the finger vein interface plate.

Description

technical field [0001] The invention relates to an access control system, in particular to a household device based on finger vein recognition. Background technique [0002] In recent years, with the rapid development of biometric technology, fingerprint authentication has been widely used. Authentication methods such as iris, voice, face, palm vein, and finger vein with higher security features are also increasingly used. Among them, the finger vein authentication method has been more widely used due to its advantages of high confidentiality, non-replication, convenient authentication, and small size of authentication equipment. The hemoglobin of red blood cells in human veins is the reduced hemoglobin of oxygen, and the reduced hemoglobin absorbs near-infrared rays. Therefore, when near-infrared rays irradiate fingers, only the vein part will have a weak reflection, thus forming a vein pattern image. Since the shape of finger veins is unique and stable, and each person's...
