电子密码锁设计

本设计采用目前十分流行的ATMEL公司的AT89C51作为核心元件,基于MCU强大的可编程功能,加上合理的软硬件设计,实现电子密码锁功能。密码位数3-6位可任意设定,且设有万能密码,在忘记使用密码时,亦可开锁。操作时有相应的声音响应,当输入错误密码次数超过设定次数时,能通过串行口向监控部门发出警报,监控部门能发出语音告警,且能显示发出警报的用户号,监控部门还可以自定义不大于20S的语音报警的声音。用户也可根据自己情况修改用户号和密码,增强了通用性。

The Design of Electronic Code Lock

This design uses the currently popular ATMEL Corporation AT89C51 as a core component,based on the powerful programmable MCU functions,together with reasonable hardware and software design to achieve the functionality of electronic password.3-6 digit password bit can be set arbitrarily,it has universal password,the lock can be opened even the password is forgotten。 When the times that you enter your password wrong more than the number set,the lock can first issues a warning through the serial port to monitor the department,monitoring departments can issue voice alarm,and can display alerts the user number,monitoring departments also can customize the voice is not more than 20S alarm sounds.Users can also modify the user according to its own number and password,and enhanced versatility.
