资料介绍

文章介绍了以STC12C5A60S2单片机为主控芯片的指纹门禁系统设计与实现。主要包括光学生物指纹采集模块、语音模块、旋转编码器。指纹模块通过串口与单片机通信,将获取的指纹信息传给单片机实现指纹信息的管理,当指纹模块检测到有手指放在光学指纹传感器上时,指纹模块会自动扫描用户指纹,将之与指纹存储器中的指纹进行特征匹配。若匹配成功,上位机传达匹配成功的指令,驱动电磁锁执行开门动作,进而实现指纹门禁功能。

This paper introduces the design and implementation of fingerprint access control system based on STC12 C5 A-60 S2 microcontroller. It mainly includes optical bio-fingerprint acquisition module, voice module, rotary encoder. The fingerprint module communicates with the single-chip microcomputer through the serial port, and transmits the acquired fingerprint information to the single-chip computer to realize the management of the fingerprint information. When the fingerprint module detects that a finger is placed on the optical fingerprint sensor, the fingerprint module automatically scans the user fingerprint, and the fingerprint memory is matched with the fingerprint memory. The fingerprint in the feature is matched. If the matching is successful, the upper computer transmits the command that the matching is successful, and drives the electromagnetic lock to perform the opening operation, thereby implementing the fingerprint access control function.
