1、毕业设计数字钟的设计摘要:随着电子工业的发展,电子产品日新月异。钟表的数字化给人们生产生活带来了极大的方便,而且大大地扩展了钟表原先的功能。诸如数字钟、万年历、电子表、定时自动报警、定时启闭电路、通断动力设备,甚至各种定时电气的自动启用、通信、网络等众多领域,所有这些都是以钟表数字化为基础的。由于其功能的不断增加,使用方便性不断提高,很多产品已经成为人类日常生活中不可或缺的助手。本文是基于单片机控制的数字钟系统的设计。该系统主要以单片机芯片AT89C51为核心结合按键选择模块来控制数码管显示模块和蜂鸣器模块工作,从而实现时钟和闹钟功能,并可对时钟及闹钟的时、分、秒进行单独
2、校对,使其校正到标准时间。此设计以软件控制硬件及软硬件结合为指导思想,充分发挥单片机功能。同时,该数字钟系统还具有功耗小、成本低的特点,具有很强的实用性。由于系统实现的功能简单,因此具有一定的可扩展性。关键词:AT89C51单片机;数码管显示;ThedesignofdigitalclockAbstractWiththedevelopmentoftheelectronicsindustry,electronicproductsaredifferentfrombeforedaybyday.Watchesdigitalhasbroughtgreatconveniencetope
