摘要

为克服传统门禁系统价格高、安全性低的缺点

设计了一种基于STC89C52单片机的指纹密码锁系统

提出了三种解锁模式。硬件采用FPM10A光学指纹识别模块完成人体指纹录入、识别和清除等操作

结合电子密码单元实现双重开锁保护

并辅以液晶显示、按键输入、开锁控制和指示提醒等模块。软件包含各模块初始化配置和具体逻辑实现。测试结果表明:设计的指纹密码锁系统可以有效进行门禁控制

指纹识别率高

系统模块功耗低

明显提高了门禁系统的安全性和便捷性。

Abstract

In order to overcome the shortcomings of high price and low security of traditional access control system

a fingerprint password lock system based on STC89 C52 MCU is designed. Three unlock modes are proposed. The hardware uses FPM10 A optical fingerprint module to complete the operations of human fingerprint input

identification and removal

combined with electronic password unit to achieve double unlocking protection

and supplemented by LCD display

key input

unlocking control and instruction reminder modules. The software contains the initial configuration of each module and the specific logic implementation. The test results show that the fingerprint password lock system can effectively control the entrance guard

it has high fingerprint identification rate and low power consumption of system module

the security and convenience of the access control system are obviously improved.
