中文题目:基于STC12C5A60S2单片机的智能门锁系统的设计与实现外文题目:DESIGN AND IMPLEMENTATION OF INTELLIGENT DOOR LOCK SYSTEM BASED ON STC12CA60S2 MCU毕业设计（论文）共 64页（其中：外文文献及译文6页）图纸共0张完成日期2016年6月答辩日期2016年6月PAGE IIPAGE I摘要在互联网与电子科技高速发展普及的今天，智能产品大量涌入人们生活中，但在居民生活应用方面仍有很大的发展空间。本系统基于51单片机，3.7V锂电池供电，设计了一款智能门锁，使用LCD1602显示屏作为交互界面，实现状态显示，4×4矩阵键盘作为密码输入端口，实现键盘解锁，HC-05蓝牙模块作为与Android连接的端口，使用Android智能手机输入密码解锁，SIM800L短信模块作为短信发送与接收的端口，实现短信解锁，门锁状态通知等功能。系统使用简单、响应快捷、安全方便，为居民家庭财产提供安全保障，也解决了没有钥匙无法开锁的问题，具有一定应用价值。关键词：单片机；电子锁；密码锁；AbstractToday in the popularity of Internet and the rapid development of electronic technology, intelligent products influx of peoples life, but in the application of life of the residents there are still much room for development. The system based on 51 MCU design a smart door lock, as interactive interface, to achieve the state display with LCD1602 display, 4 * 4 matrix keyboard as a password input port and unlock the keyboard. HC-05 Bluetooth module as the port connected with the Android, Android smartphones to enter a password to unlock, SIM800L SMS module as text messages to send and receive port, a short letter to unlock door Lock status notification, 3.7V lithium battery power supply. The system is easy to use, fast response, convenient and safe, for the residents of the family property to provide security, also have not solved the key to unlocking, has certain application value.Key words：MCU；Electronic lock; Password lock;目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc21442 引言 PAGEREF _Toc21442 1 HYPERLINK \l _Toc19702 1 项目概述 PAGEREF _Toc19702 2 HYPERLINK \l _Toc22899 1.1 选题背景 PAGEREF _Toc22899 2 HYPERLINK \l _Toc19933 1.2 目的及意义 PAGEREF _Toc19933 2 HYPERLINK \l _Toc23663 1.3 国内外研究现状与发展趋势 PAGEREF _Toc23663 2 HYPERLINK \l _Toc247 2 相关技术 PAGEREF _Toc247 3 HYPERLINK \l _Toc10138 2.1 单片机技术 PAGEREF _Toc10138 3 HYPERLINK \l _Toc10289 2.2 矩阵键盘行列扫描技术 PAGEREF _Toc10289 3 HYPERLINK \l _Toc30042 2.3 按键去抖技术 PAGEREF _Toc30042 4 HYPERLINK \l _Toc23490 2.4 串口通信技术 PAGEREF _Toc23490 4 HYPERLINK \
