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. Platform: |
