系统由单片机、显示器、键盘等部分组成，利用显示器来显示密码锁输入的相关信息，系统上电时内部默认一组数字密码（4位或4位以上）；通过键盘可以设置新密码，或进行密码校验，密码输入正确则模拟打开密码锁，密码输入错误则发出警报。-



System consists of microcontroller, monitors, keyboards and other components, the use of monitors to display information about locks input, the system power when internal default password for a set of numbers (4 or 4 above)　you can set a new password via the keyboard, or password verification, enter the correct password to open the analog lock, password input error is alert.
