Title:
VISITOR SYSTEM USING PALMAR VEIN RECOGNITION
Document Type and Number:
WIPO Patent Application WO/2020/048011
Kind Code:
A1
Abstract:
A visitor system using palmar vein recognition, comprising a power supply, a power supply driver circuit, a palmar vein collection circuit, an SD card, an SD card interface circuit, an ARM processor higher than cortex A8, an LCD display circuit, an LCD display screen, an audio output circuit, a loudspeaker, an RS232/485 communication conversion circuit, and an access controller. The power supply is connected to the ARM processor higher than cortex A8 by means of the power supply driver circuit; the palmar vein collection circuit is connected to the ARM processor higher than cortex A8; the SD card is connected to the ARM processor higher than cortex A8 by means of the SD card interface circuit; the ARM processor higher than cortex A8 transmits intercom visual information to the LCD display screen by means of the LCD display circuit, and outputs an audio prompt by means of the audio output circuit and by means of the loudspeaker; the ARM processor higher than cortex A8 controls logic communication between palmar vein recognition and the circuits, and is provided with a near infrared LED camera. Palmar vein image extraction and digital processing are performed on a visitor.
