红外遥控电子密码锁的设计
红外遥控电子密码锁的设计(任务书,开题报告,外文翻译,论文12000字)
摘要
随着现代社会城市化的提高，家庭防盗问题日益突出。结构简单的传统机械锁被撬的事件被盗的几率非常之高，而新型的红外密码电子锁在保证安全性的情况下操作简单方便，是传统锁的理想替代品。
本论文的电路系统的核心控制器件为一片stc89c52单片机，使用红外遥控器达到开锁的目的。本文在介绍了红外通讯的基本原理基础上，介绍了系统总体方案设计和论证，其硬件部分由单片机最小系统、LCD1602显示电路、数据存贮电路、继电器和报警电路组成，其后分析了系统开锁时软硬件各模块如何实现，介绍了相关软件Proteus ISIS和KeiluVision，其软件部分采用模块化设计，整个程序分为主程序、显示程序、延时程序、红外发射接收程序等，从而实现了利用矩形键盘红外遥控输入密码，通过LCD1602显示屏显示解锁流程等功能。在论文最后展示了实物效果，并给出了总结。
测试结果表明本系统以实现所要求的各项功能。
