基于TMS320DM642静脉识别的储物柜系统设计

摘要

A design method of vein recognition system controlling lockers based on TMS320DM642 is proposed based on the existing vein recognition algorithm.The system is mainly composed of the electromagnetic locks,the electromagnetic locks controller and a central pro-cessing controller.During the stored procedure,the generated ID number is required to bind with the number of lockers,then the door is open.During the removed procedure,it needs to verify the vein in order to open the locker,then removes vein information finally.On the basis of original,the vein recognition replaces the barcode.This approach is safer than the verification of barcode,and it is not easy to lose.%在现有静脉识别算法的基础上,提出了一种基于TMS320 DM642的静脉识别控制储物柜的方法.该系统主要由电磁锁、电锁控制器和中央处理器组成.存储过程中采集静脉,生成的ID需要与储物柜号绑定,柜门打开;取出过程中,需要静脉验证,打开与其绑定的柜门并删除对应的静脉信息.在原有的基础上,静脉验证取代条形码,这种方法比条形码验证更安全,不易丢失.
