Title:
FINGER VEIN IDENTIFICATION-BASED SMART BUILDING VISUAL INTERCOM SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/019680
Kind Code:
A1
Abstract:
A finger vein identification-based smart building visual intercom system, comprising a power source, a power source driver circuit, a finger vein collection circuit, an SD card, an SD card interface circuit, a single chip, an LCD display circuit, an LCD display screen, an audio output circuit, a speaker, an RS-232/485 communication conversion circuit, and an access controller; the power source is connected to the single chip via the power source driver circuit; the finger vein collection circuit is connected to the single chip; the SD card is connected to the single chip via the SD card interface circuit; the single chip transmits visual intercom information to the LCD display screen via the LCD display circuit; the access controller is connected to the RS-232/385 conversion circuit to control door opening and closing; and the single chip controls logical communication between finger vein identification and a circuit. The access control method of the present system employing finger vein biometric identification technology can accurately identify users and control the access control system, ensuring safety in residential areas.
