摘要
在当代繁忙的工作与生活中，时间与我们每一个人都有非常密切的关系，
每个人都受到时间的影响。我们必须对时间有一个度量，因此产生了钟表。
钟表的发展是非常迅速的，从刚开始的机械式钟表到现在普遍用到的数字式
钟表，即使现在钟表千奇百怪，但是它们都只是完成一种功能——计时，只
是工作原理不同而已，在人们的使用过程中，逐渐发现了钟表的功能太单一，
没有更大程度上的满足人们的需求。因此在这里，我想能不能把一些辅助功
能加入钟表中去。在此设计中所设计的钟表具有钟表的功能。
本系统采用了以广泛使用的单片机技术为核心，软硬件结合，使硬件部
分大为简化，提高了系统稳定性，并采用 LCD 显示电路、键盘电路，本方案
设计出的万年历可以显示日期时间、农历，设置闹铃功能。
In busy job of the present age and life, time has very close something to do with all of us ,
everyone all accepts the time effect. we must have a magnanimity to time , have produced clock
and watch therefore. Development of clock and watch is very prompt , use clock and watch to the
digital from just originally mechanical dyadic clock and watch to now commonly, even if now clock
and watch is exceedingly strange, they accomplish but one kind of time function of function all only ,
are only operating principle diversity, in the process of people's usage, the function having
discovered clock and watch gradually is very unitary, need not having the satisfied people on bigger
degree. Want to be able to I put some auxiliary function in going to in clock and watch therefore in
here. Function designing that middle what be designed that clock and watch has average clock and
watch's .
And the monolithic machine technology that this system has adopt to use broad usage has been
that core , soft hardware combine , the hardware part has facilitated a messenger extremely , has
raised system stability, adopt LCD demonstrates circuit , keyboard circuit , The perpetual calendar
that the scheme designs out can demonstrate date time , unar calendar , set up the noisy bell
function.
