本设计中,电子密码锁使用STC89C52单片机控制,采用 C语言编写,通过Proteus软件仿真并进行了实物焊接。电子密码锁通过矩阵键盘进行密码输入,1602A液晶显示模块进行显示。其可实现的功能有:(1)通过切换,对输入的4位密码进行显示或隐藏;(2)通过发光二极管和蜂鸣器,对解密正确或者错误进行声光报警;(3)4位密码修改;(4)在密码遗失情况下,通过初始密码进行密码再设置;(5)采用AT24C02外部存储器,完成断电密码保护功能;(6)具有1-9次的解锁次数任意设定功能;(7)模拟密码箱随机产生密码,并进行解码。本设计特色为采用1602A液晶显示模块,这使得显示更加直观、使用更加方便。密码可实现显示和隐藏切换,通过隐藏密码实现密码保护。-In this design, the electronic code lock use STC89C52 SCM using C language by Proteus software simulation and physical welding. Electronic lock matrix keyboard for password input, 1602A LCD module for display. Its function can be realized: (1) by switching the input four passwords to display or hide (2), right or wrong of the decryption by light-emitting diode and buzzer sound and light alarm (3) 4 (4) In the case of password is lost, the initial password for password re-set password is modified (5) the AT24C02 external memory to complete the power-off password protection (6) have 1-9 times the number of unlock any set given function (7) analog password box randomly generated password, and decoding. The design features of the LCD module using the 1602A, which makes the display more intuitive, easier to use. The password can show and hide the switch, by hiding the password to a password-protected.
