哪位大哥大姐帮忙翻译一下电子钟论文摘要 多谢了

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。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。
单片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。它体积小，成本低，功能强，广泛应用于智能产业和工业自动化上。而51系列单片机是各单片机中最为典型和最有代表性的一种。这次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。
本文通过对一个基于单片机的能实现定时，秒表，万年历，闹钟等功能的多功能电子时钟的设计学习，详细介绍了单片机应用中的数据转换显示，液晶显示原理，键盘扫描原理，单片机的定时中断原理。从而达到学习、了解单片机相关指令在各方面的应用。系统由AT89S52、温度检测芯片、时钟芯片、液晶显示器、存储器、稳压电源等部分构成，能实现时钟日历显示的功能，能进行时、分、秒的显示和实时温度显示。也具有日历计算和时钟、日历的校准，定时时间的设定和闹铃等功能。文章后附有电路原理图、PCB板图和程序清单，以供读者参考。因水平有限，难免有疏落不足之处，敬请老师和同学能给与批评指正。

Computers have accelerated the transformation of the world's human pace, but it is after all bulky. SCM in this case was born. As of today, SCM application rapid development of technology, looking around us now in all spheres of life, from missiles, navigation equipment, to the various instruments on the aircraft control from a computer network communications and data transmission, industrial automation to real-time process control and data processing, and our lives extensive use of the smart card, electronic pets, which is inseparable from the microcontroller. Monolithic single-chip micro-computer or computer. (Single-Chip Microcomputer) is the set of CPU, RAM, ROM, the timing, number and variety of interface integrated microcontrollers. Its small size, low cost, high performance, which are widely used in smart industries, and industrial automation. And 51 Series SCM SCM is the most typical and the most representative one. The graduation design Through the study, and thereby achieve the study, design, development hardware and software capabilities. Based on a microcontroller based on the will to achieve timing, stopwatch, calendar, alarm clocks, and other functions of a multi-functional electronic clock design study, in detail, the computer application of data conversion, Principle LCD, keyboard scanning principle, SCM regularly interrupted principle. Thereby achieve studying and understanding the relevant directives SCM in all aspects of the application. By AT89S52 system, temperature detection chip, the clock chips, liquid crystal displays, memory, Regulators and electricity supply of components, to achieve clock calendar display function can be carried out, hours seconds of the show and real-time temperature display. Also calculated with the calendar and clock, calendar calibration, regular hours and set the alarm function. The article attached circuit diagram, the PCB plans and procedures checklist for the reference of our readers. Due to limited, and it will inevitably be lighter inadequate, locations will give teachers and students correction and criticism.
