Description: 程序功能： 本程序结合了24C02存储器的存储功能，可以掉电保存密码。第一次运行时，若输入000000原始密码后无反应，可以试验着将主程序中前面的一小段被注释线屏蔽的程序前的注释线删掉，然后重新编译下载（可以将密码还原为000000）。此后，再将这小段程序屏蔽掉，再编译下载。方可正常使用。1、开锁：下载程序后，直接按六次S7（即代表数字1），8位LED亮，锁被打开，输入密码时， 六位数码管依次显示小横杠。2、更改密码：只有当开锁（LED亮）后，该功能方可使用。首先按下更改密码键S16，然后设置相应密码，此时六位数码管会显示设置密码对应的数字。最后设置完六位后，按下S17确认密码更改，此后新密码即生效。3、重试密码：当输入密码时，密码输错后按下键S18，可重新输入六位密码。当设置密码时，设置中途想更改密码，也可按下此键重新设置4、关闭密码锁 按下S19即可将打开的密码锁关闭。-Program function: this program combines 24 c02 memory storage function, can power-fail save the password. The first operation, if the input 000000 original password no reaction, can test the main program in the front of the a small section of the comment line screening program before the comment line out, then to recompile the download (can be password reduction for 000000). Since then, then this small segment of a program, shielding off, recompilation download. Can be normal use. 1, unlocking: download procedures, directly according to six times S7 (namely represent Numbers 1), eight LED light, lock is opened, password, six digital tube display in small shaft. 2, to change password: only when the lock (LED light), this function can be used. First press to change password key S16, then set the corresponding code, the six digital tube will display set password corresponding digital. The last set the six, press S17 confirm password change, then the new password is effective. 3, retry pas

Description: 本设计介绍了电子密码锁的应用背景，基本功能和实现方法。在硬件方面，以51单片机为主控芯片，带有一个4*4的矩阵键盘作为密码输入的方式，通过1602液晶显示器提示程序运行状态和使用步骤，并采用了24C02芯片实现对密码的存储功能。利用蜂鸣器、发光二极管、继电器模拟报警和锁的开关。在软件方面，实现了密码的输入、清除、更改，删除等功能。在设计过程中引入了信息反馈的思想，使密码锁功能更灵活、更切合实际。有的按键可实现一键多用的功能，节约资源。本设计已通过Proteus软件成功仿真的电子密码锁的实现过程，并完成实物。-This paper introduces the electronic combination lock application background, basic function and implementation method. In terms of hardware, this design uses 51 single-chip microcomputer as main control chip, with a 4* 4 matrix keyboard as a means of password entry. It adopts 24C02 chip to complete the code s memory function, using LCD 1602 to prompt the program s running state and working procedures, adopting buzzer,LED and relay to imitate the alarm and the lock switch. In the aspect of software, it realizes the password input, remove, change, delete, etc. That it introduces the ideas of information feedback makes the combination lock function more flexible, more practical. A key to achieve some keys can use function, saving the resource. The electronic code lock was successfully simulated by Proteus, at the same time , the entity also was completed.
