1、- 1 - 基于 DS1302 的电子万年历设计 专业班级： 06 级通信 1 班 学生姓名： 指导教师： 职 称：讲师 摘 要： 现在是一个知识爆炸的新时代，新产品、新技术层出不穷，电子技术的发展更是日新月异。可以毫不夸张的说，电子技术的应用无处不在，电子技术正在不断地改变我们的生活，改变着我们的世界。在这快速发展的年代，时间对人们来说是越来越宝贵，在快节奏的生活时，人们往往忘记了时间，一旦遇到重要的事情而忘记了时间，这将会带来很大的损失 。因此我们需要一个定时系统来提醒这些忙碌的人，而数字化的钟表给人们带来了极大的方便。由于单片机具有灵活性强、成本低、功耗低、保密性好等特点，所以电子日历时
2、钟一般都以 DS1302 为核心，外加一些外围设备来实现。 近些年，随着科技的发展和社会的进步，人们对数字钟的要求也越来越高，传统的时钟已不能满足人们的需求。多功能数字钟不管在性能还是在样式上都发生了质的变化，有电子闹钟、数字闹钟等等。单片机在多功能数字钟中的应用已是非常普遍的，人们对数字钟的功能及工作顺序都非常熟悉。但是却很少知道它的内部结构以及工作 原理。由单片机作为数字钟的核心控制器，可以通过它的时钟信号进行计时实现计时功能，将其时间数据经单片机输出，利用显示器显示出来，通过按键可以进行定时、校时功能。输出设备显示器可以用液晶显示技术和数码管显示技术。 关键词 ： DS1302 实时钟
3、万年历 The Design of The Simple Logic Controller Based on SCM Abstract： Now a new era of knowledge explosion, new products, new technologies emerge in endlessly, the development of electronic technology is changing. It is no exaggeration to say, electroni c technology applications everywhere, electroni
4、c technology is changing our life, and our world. In this fast development, the time is more precious to people in the fast pace of life, people often forgotten when time, once encounter something important and forget time, this will bring great loss. So we need a regular system to remind those busy
5、 people, and digital clocks bring great convenience. Due to the microcontroller has flexibility, low cost, low power consumption, the secrecy is good wait for a characteristic, so the electronic calendar clocks are generally based on DS1302, plus some peripheral equipment to achieve. In recent years
6、, with the development of science and technology and the progress of the society, the people of a digital clock higher requirements, the traditional clock already cannot satisfy the demands of the people. Multi-functional digital clock in performance or in style have undergone a qualitative change,
7、electronic alarm clock, number, etc. Microcomputer in the multi-function digital clock application is very common, and has the function of digital clock and work order is very familiar with. But few know its internal structure and work principle. By single chip microcomputer as the core controller,
8、digital clock through its clock signal timing realize its function, the clock time data using SCM outputs, display, through the buttons can be regularly, school when function. Output devices with LCD monitors can display technology of digital technology and the pipe. Keywords: DS1302 calendar clock.
