摘要
本文设计了一套基于Linux指纹识别门禁系统。该系统由FPI指纹识别模块、Raspberry Pi主控模块、AVR模块的三方通讯实现用户的指纹录入和匹配,以及门锁的开关。在Linux下编写控制程序,通过串口的方式实现Raspberry Pi主控模块与AVR以及FPI之间进行通信,利用Shell脚本程序定时向用户发送邮件来监控门锁的状态,通信部分采用无线方式实现。实验表明,该指纹识别门禁系统采集与预处理速度快,性能稳定、可靠。
A system of fingerprint entrance guard is designed based on Linux which can complete user＇s fingerprint enrollment , matching and controlling of the door＇s status by the three-way communication of the FPI fingerprint identification module , Raspberry Pi control module and AVR. With the help of Linux control procedures, the communication among Raspberry Pi , AVR and FPI is realized by the UART, and shell program is used to send email to user at a regular time to monitor the status of the door ,and the communication part is based on the wireless manner to be achieved . The fingerprint entrance guard system can reach at the high speed of collecting and preproeessing with stability and reliability.
