摘要

一寸光阴一寸金，时间的宝贵我们不言而喻。因此树立正确的时间观念是每个人走向成功的一项基本要求。而闹钟正是帮助人们树立正确的时间观念所必要的工具。尤其对一些自控能力差的学生。

闹钟有很多种类，机械的、石英的，自从它被人利用钟摆的原理发明以来已经成为人们生活中不能缺少的物品。它既能指示时间，又能按人们预定的时刻发出音响信号或其他信号。

本报告介绍了闹钟的发展现状和人们对闹钟及时间观念的认识以及一种智能音乐闹钟的初步设计方法。本调研主要针对在校大学生对时间观念和闹钟作用的认识，采用多种调研方法综合分析得出闹钟的发展现状和它对树立时间观念的作用以及其市场前景。本设计是由中央控制器、时钟系统、显示器及键盘部分组成。控制器采用单片机，时钟系统采用相应的实时时钟芯片，它将产生的时间信号传递给单片机，单片机通过74LS48译码，使LED 8段数码管显示当前的时间,在计时过程中当到达所设定的闹铃时间后，将播放提示性语句，并且此时LED 数码管所显示的不再是时间而是一个代码，只有用户在将这个代码从键盘上正确的输入进去，才能将其声音关闭，否则声音将一直播放下去。用户可以通过键盘设置闹铃的时间和校正时间以及输入相应提示性语句。

关键词：单片机、智能闹钟

Abstract

An inch of time is an inch of gold, the value of time we are self-evident. Therefore, to establish the correct concept of time is for everyone to an essential requirement for success. While the clock is to help people establish correct concept of time the necessary tool.

There are many types of alarm, machinery, quartz, since it has been used since the invention of the pendulum principle has become the people to live an indispensable. It can indicate the time, and can according to the predetermined time sound signals or other signals.

This report describes the development situation and the people to the alarm clock and time concept understanding and intelligent music alarm clock at the preliminary design stage. This research mainly aimed at college students to the concept of time and alarm clock function understanding, using a variety of research methods of comprehensive analysis the development status and its clock to set up the concept of time effect and its market prospect. This was designed by the central controller, clock system, display and keyboard parts. The controller uses the monolithic integrated circuit, clock system uses the corresponding real-time clock chip, it will generate a time signal to the microcontroller, microcontroller through 74LS48 decoding, the LED digital tube display is not time but a code, only users in the code from the keyboard to the correct input in, in order to sound off, otherwise the sound will have to play all the time. Users can set the alarm via keyboard and input the corresponding time and correction time prompted statement.

Key words: single chip microcomputer, intelligent alarm clock
