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。为了更好的利用我们自己的时间，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——计时功能，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不但具有普通钟表的功能，它还能实现额外的功能：世界时、农历显示。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LED显示电路、键盘电路，使人机交互简便易行，此外结合音乐闹铃电路、看门狗和供电电路。本方案设计出的万年历可以显示日期时间、世界时、农历，设置闹铃功能。

In the busy work and life, time and each of us has a very close relationship, each time people have been affected. In order to make better use of our own time, we must have a measure of time, resulting in a timepiece. Watches and clocks, development is very rapid, from the beginning of the mechanical clocks to the now widely used in digital watches and clocks, watches and clocks, all sorts of strange things even now, but they have just completed a function -- the timing function, just principle is different, in the use process, gradually found the clock function is too single, no more a large extent to meet the needs of people. So here, I think can make some auxiliary function to the clocks go. In this design the design of the clock has not only ordinary clock function, it can also achieve additional functions : the world, calendar display. The system uses a widely used microcontroller as the core technology, software and hardware combination, so that greatly simplified hardware, improve the system stability, and the use of LED display circuit, keyboard circuit, is easy to machine interaction, in addition to combine music alarm circuit, watchdog and power supply circuit. The program designed to show the date of the calendar time, world, lunar, set the alarm function.

In contemporary busy work and life, time and every one of us has a very close relationship, everyone is the influence of the time. In order to make better use of our own time, we must have a measure of time, resulting in a clocks and watches. The development of the clock is very rapid, from the start of mechanical timepieces to widespread use of digital clock now, even now various clock, but they were just completed a function-timing function, just work principle different just, in people's use process, gradually found that the function of the clock is a single, no more degree to meet the people's needs. So here I think can make a few auxiliary function to join in the clock. In the design of design ?
