电子时钟因其计时准确、外形美观、价格低廉而深受人们的喜爱并在日常生活中得到广泛的应用。系统是基于实时时钟芯片DS1302制作的电子钟。控制芯片采用AT89S51单片机，由单片机模块，时钟电路模块，LED显示电路模块，按键电路模块等几部分组成。能显示年，月，日，时，分，秒并能通过按键对时间和日期进行调整。具有显示模式选择功能,用户可以选择只显示时间模式或时间和日期交替显示模式。系统电路结构简单，性能可靠，掉电不影响走时使用十分方便。

Accurate electronic time clock for its beautiful appearance, low price and very popular and widely in daily life applications. System is based on real-time clock chip DS1302 produced electronic bell. AT89S51 chip control MCU, from single-chip module, the clock circuit module, LED display circuit module, circuit module, such as a few key parts. Showing the year, month, day, hour, minute, second and through the time and date button to adjust. With a choice of display mode, users can choose to display only time mode or the turn of the time and date display mode. System circuit of simple structure, reliable performance, power-down does not affect the travel time is very convenient to use.
