摘要
现在电子时钟在越来越多的领域得到了应用,尤其是对某些无人看守的测控系统及有关的自动化控制等对时钟精确度要求很高的场合,电子时钟具有十分重要的应用价值。文章利用时钟芯片DS1302,AT89C52单片机以及数码管等元件,设计新的数字时钟电路,实现定时、计时、报警等功能。经大量的仿真实验验证,设计的数字时钟显示时间正确,工作具有较高的准确性和可靠性。
Now electronic clock has been applied in more and more areas,especially for some unmanned control system and automatic control places where the clock accuracy requirements are high,it is of very important value.This article uses the clock chip DS1302,AT89C52 microcontroller and digital tube components to design a new digital clock circuit,which can achieve setting alarm clock,timing,calling the police and other functions.Through a large number of simulation experiments,it is verified that digital clock designed displays the correct time,and works with high accuracy and reliability.
