多功能智能电子钟的设计

Design of Intellectual Electronic-Clock of Multifunction

多功能智能电子钟以AT89C2051芯片为核心,采用静态与动态相结合的扫描方式显示。系统软件包括主程序和中断模块,基本时间、总天数、星期、公历、阴历等日历算法模块。其显示模块采用单片机串行输出,以分时动态扫描方式点亮21块LED数码管和4个发光二极管。

The chip of AT89C2051 is based on as the core of intellectual electronic-clock, and the scanning mode is applied to display by combining dynamic scan with static scan. The system software includes： main program, interrupt program and the programmed algorithm about calendar of basic time, total days, week, the Gregorian calendar and the lunar calendar. The displaying module is designed with serial output of one chip computer, 21 pieces of LED nixie light and 4 pieces of LBDs were lighted up by the way of dynamic time-sharing scan.
