Embedded Access Control System Design Based On Palm Vein Recognition

Traditional access control technologies mainly use keys, IC cards, passwords and othersfor identification, however, which have many defects,such as easily stolen, easily forged,easily lost, easily forgotten and many other issues. To solve these problems to people withsecurity risks and living in distress, for which we designed a palm vein recognitiontechnology for authentication embedded access control system.This paper we first explains the Access Control System, including the composition,function, classification, analysis of the disadvantages of traditional access control technology.Then introduce the principle and advantages of hand vein recognition technology in detail,and compared with other recognition to show the advantages of the palm vein recognition. Tomake way for palm vein recognition technology and better integration with access control, thepaper chooses full-Chi A20dual-core ARM microprocessor core as the embedded controlsystem hardware design, moreover, accomplishes design of the power supply module,Ethernet communication module, storage devices and a variety of interface circuits usingfull-Chi A20microprocessor.Finally, after debugged the equipment, we found that the low temperature led to theentrance guard system certification success rate is low in winter in the Northern Region.Therefore, we design the heating system, the entrance guard system to normal operation inwinter. Meanwhile, in order to make the property provide better play services for arearesidents，and enjoy the advantages of better intelligence community. We have designed thecorresponding management system software.
