题目基于单片机的电子密码锁的设计
摘要:
随着科技的不断发展,人们越来越重视对具有私密、重要物质的场所的安全性,所以具有报警功能的电子密码锁在日常生活中用的越来越多,因此研究与设计单片机为主要控制器的电子密码锁具有工程意义和解决日常应用需求的价值。
本电子密码锁的设计采用以单片机STC89C52RC为主控制器,应用矩阵键盘、SMC1602A液晶显示器、STC89C52RC内部的EEPROM等器件进行设计了键盘电路、液晶显示电路、UART串口电路、电源(5V)电路、指示(LED)电路、报警(蜂鸣器)电路等电路设计;应用protel软件设计了硬件原理图和PCB图;应用C51语言设计了显示时间和校对时间、输入密码和修改密码、控制EEPROM等软件模块;最后焊接PCB并调试电路。最终设计出一个具有等待状态显示时间(可以对时间进行校准)、输入密码、修改密码、密码正确与否指示、报警、密码保护、一键还原初始密码等功能的密码锁。设计此系统具有较高的安全性和科学性。

Title Design of Electric Coded Lock Based on MCU
Abstract
As technology continues to evolve, there is growing emphasis on having a private, important material security of the place, so the alarm function of electronic locks used in everyday life, more and more, so the research and design of microcontroller as the main controller's electronic locks with engineering significance and value of solving everyday applications.
The electronic locks are designed using a microcontroller STC89C52RC main controller, application matrix keyboard, SMC1602A LCD monitors, STC89C52RC internal EEPROM devices such as the design of the keyboard circuit, liquid crystal display circuit, UART serial circuit, power supply (5V) circuit, indicating (LED) circuit, alarm (buzzer) circuit, circuit design; protel software application designed hardware schematics and PCB map; C51 language designed application displays the time and checking the time, enter the password and change passwords, control software modules such as EEPROM ; finally soldered PCB and debug circuits. The final design of a status display with waiting time (time can be calibrated), enter your password, change your password, the password is correct or not indication, alarm, password protection, a key to restore the initial password lock and other functions. Design of this system with high security and scientific.
