基于单片机的数字时钟的原理与制作
摘 要
小三号宋体(粗体)居中
单片机在数字时钟中的应用已是非常普遍的,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。通过键盘可以进行校时、定时等功能。输出设备显示器可以用液晶显示技术和数码管显示技术。
本次设计是利用单片机实现具有计时、校时、整点报时等功能的数字时钟,是以单片机AT89C51为核心元件同时采用LED数码管显示器动态显示“时”,“分”,“秒”的现代计时装置。本文详细阐述了单片机和LED数码显示器的内部结构,系统硬件电路和软件程序的设计及调试过程,同时给出了原理图、流程图等。涵盖了从需求分析,系统设计,编程,原理图,PCB图以及最后的试验板焊制等产品开发的基本过程。

Principle and production of digital clock based on
Single Chip Microcomputer
Abstract
Single Chip Microcomputer is already very common in the application of digital clock, as the core controller of a digital clock, SCM can achieve the function of timing via its clock signal. And its time data can be exported via SCM and displayed by the monitor. Keyboard can achieve the function of timing and clocking, to name just a few. The Liquid-crystal display technology and Digitron display technology can be applied in the output device monitor.
This design is utilizing the SCM to produce the digital clock with the functions of clocking, timing, announcing the time on the hour and so on. It is a modern timing device, among which the SCM AT89C51 is the core element. Meanwhile, LED digitron monitor dynamically display the “hour”“minute”“second”. This dissertation elaborates the interior structure, system hardware circuit and the process of software program's design and debug of SCM and LED digitron monitor in detail. Meanwhile, schematic diagram and flow chart are also contains the basic process of requirement analysis ,system design,SCM programming , schematic diagram, PCB chart and final welding of the boar
