摘要
 数字钟是采用数字电路来实现时，分，秒的数字显示的计时装置。广泛用于家庭，车站, 码头，办公室等公共场所,成为人们日常生活中的必需品。由于数字集成电路的发展和石英晶体振荡器的广泛应用,数字钟的精度远远超过老式钟表, 钟表的数字化给人们的生产生活带来了极大的方便。
 毕业设计主要实现语音报时的多功能数字钟。以凌阳SPCE061A单片机作为控制核心并利用其自带的语音芯片实现任意时刻的语音报时。和普通单片机相比较，此方案不需要附加的语音芯片，因此结构简单。利用SPCE061A的简易开发板“61板”可以在线编程在线调试,可直接调用语音播放函数，可大大地简化工作量，缩短开发时间。采用DS12887实现计时，利用其自带的电池可保证掉电情况下仍可完成计时功能，可以对其方便地进行程序控制。

ABSTRACT
 Digital Clock is a time counting devices using digital circuits. It’s widely used in families, stations, docks, offices and other public places and has become a necessity in daily life. Due to the development of the digital integrated circuits and the application of quartz crystal oscillators, the precision of the digital clock has far exceeded the old ones. Digital clocks give the people's work and daily life a great convenience.
 The design of a multi-function digital clock with voice time report is the main goal. The SPCE061A (a SCM from Sunplus corp.) is used as the core controller. It’s easy to realize arbitrary voice time report with its built-in speech chip. Compare With other general SCMs, this scheme does not need any additional speech Chips. So its structure is simpler. Using the "61 boards" (a simple SPCE061A Development Board), we can program and debug online. The predefined API functions can directly used to realize Speech Synthesis. So we can greatly simplify the developing progress save a lot of time. The DS12887 chip is provides the current time. It can keep working even the main power is off. It also can be controlled by programming.
