摘　　要：针对传统机械锁、卡片钥匙式电子锁及电子密码锁等存在的问题,提出基于单片机的以指纹和密码共同控制的指纹密码锁,使系统更加安全、便捷和智能化。采用STM32F103ZET6单片机控制指纹模块,同时与指纹模块进行信息交互,指纹模块正常响应后自动进入指纹识别过程;采用TFTLCD液晶触摸屏实现对人体指纹的录入、清除等功能;指纹模块正常识别后,进入密码输入系统,用户根据TFTLCD液晶触摸屏的提示使用默认密码、进入管理员界面修改密码及掉电保存密码等功能;当密码输入符合要求时,电磁锁自动打开,用户可以进入室内或执行其他部件,完成后续功能。Considering matters bothering traditional mechanical locks,card key E-locks and electronic coded locks,a fingerprint password lock based a combination of STM32F103ZET6 SCM and fingerprint password was proposed which boasts of high safety,convenience and intelligence.In which,the STM32F103ZET6SCM controls and interacts with the fingerprint module;when the fingerprint module normally responds,it automatically enters the fingerprinting process.The TFTLCD touch screen adopted can realize the entry and removal of human fingerprints.The fingerprint module,after normal recognition,enters password input system;users,according to the prompt of TFTLCD touch screen,employs the default password for the administrator interface changes,saving the password at power-down time.The electromagnetic lock opens when the password is correctly input as required,meanwhile,the user can enter indoor or other parts and complete follow-up functions.
