昆明工业职业技术学院 目录 PAGE  昆明工业职业技术学院 班 级 电气自动化三班 学 号 2008212449 用单片机实现电子时钟 姓 名 专 业 电气自动化 指导教师 二〇一〇年六月十八日 昆明工业职业技术学院 摘要  PAGE I 摘 要 单片机计算机即单片微型计算机。（Single-Chip Microcomputer ）,是集CPU ,RAM ,ROM ,定时，计数和多种接口于一体的微控制器。他体积小，成本低，功能强，广泛应用于智能产品和工业自动化上。而51 单片机是各单片机中最为典型和最有代表性的一种。这次 HYPERLINK  HYPERLINK 毕业设计通过对它的学习应用，从而达到学习、设计、开发软、硬的能力。时钟，自从它发明的那天起，就成为人类的朋友，但随着时间的推移，科学技术的不断发展，人们对时间计量的精度要求越来越高，应用越来越广。怎样让时钟更好的为人民服务，怎样让我们的老朋友焕发青春呢？这就要求人们不断设计出新型时钟。计算机的产生加快了人类改造世界的步伐，但是它毕竟体积大。单片机在这种情况下诞生了基于单片机电子时钟，截止今日，单片机应用技 术飞速发展，纵观我们现在生活的各个领域，从导弹的导航装置，到飞机上各种仪表的控制，从计算机的网络通讯与数据传输，到工业自动化过程的实时控制和数据处理，以及我们生活中广泛使用的各种智能IC卡、电子宠物等，这些都离不开单片机。 【关键词】：电子,时钟 Abstract That is, single-chip computer-chip micro-computer. Is a set of CPU, RAM, ROM, from time to time, the count in one interface and a variety of microcontrollers. His small size, low cost, feature strong, smart widely used in industrial automation products and on. The 51 single-chip MCU is the most typical and most representative one. The graduation project through its study and application in order to reach the study, design, development software and hardware. Clock, since its invention of the day, they become friends, but as time goes by, science and technology development, people on the precision of time measurement have become increasingly demanding, more and more widely applied. How to let the clock to serve the people better, how we let an old friend of the rejuvenated it? This requires people to design a new type of clock. The computers have accelerated the pace of human change the world, after all, but it bulky. In this case, single-chip was born. As of today, single-chip application of the rapid development of technology
