电子密码锁的设计

本设计以AT89C51单片机为控制核心,结合矩阵键盘、24C04A存储系统等来完成电子密码锁的设计。单片机接收键入的代码后,与存贮在24C04A的密码进行比较,如果密码输入正确,则锁将打开;如果输入不正确则系统报警,但是允许接着输入密码,直到输入正确,系统开锁,设计达到预期效果。

The design use AT89C51 as a core component, combined with matrix keyboards, 24C04A storage system to complete the design of electronic password. MCU receives the type of code, and compare with the password storing in the 24C04A, if the password is entered correctly, the lock will open; if the input is not correct, the system alarm, but then allowed to enter the password until the correct input, the system lock, the design achieve the expected effect.
