FPGA-based face, finger and palm print, voice and weight composite identification access control system

Abstract

The invention discloses an FPGA-based face, finger and palm print, voice and weight composite identification access control system. The composite identification access control system comprises an FPGA data processing module, a face collector, a finger and palm print collector, a voice collector, a weight collector, a data accessing module, a display module, an access controller, an access lock, a loudspeaker, networking protocol firmware and an access control management terminal; the four collectors transmit data information collected separately to the FPGA data processing module, then the data information is transmitted to the data accessing module through the FPGA data processing module for being stored or compared with information stored in the data accessing module; when all identity identification is consistent, the identification result is 'pass', and the access lock is opened through the access controller; when one of identity identification is not consistent, an arbitration can be applied to the management terminal, and when the identification result is 'not pass', the access lock is closed through the access controller. Through such a way, the safety and practicability of the access control system are high, the cost for upgrading and updating is low and the computation speed is fast.

Description

technical field [0001] The present invention relates to the improvement of a compound recognition access control system, especially a FPGA-based face, finger palm print, voice and weight compound recognition with high security, low cost of upgrading, high practicability and faster calculation speed access control system. Background technique [0002] Many companies, hotels, schools, office buildings and other units have installed access control systems, which has improved the level of intelligent management of personnel entering and leaving the unit, and ensured the safety of the unit's property. Although existing access control systems such as magnetic cards and IC cards with single-chip microcomputers as the data processing center have brought a lot of convenience to people, the loss of magnetic cards and IC cards or data being copied by people has brought many problems to the use of traditional magnetic cards and IC card access control systems. A lot of inconvenience. W...

Problems solved by technology

However, a single identification information is easy to be forged, and the upgrade of the single-chip microcomputer needs to replace the hardware as a whole, which brings many difficulties to the user unit
