摘　　要：电子万年历是单片机系统的一个应用,本设计由硬件和软件两部分组成,硬件由主控器、时钟电路、温度检测电路、显示电路、键盘接口5个模块组成,主控模块用AT89C52、时钟电路用时钟芯片DS12C887、显示模块用LCD、温度检测采用DS18B20温度传感器、键盘接口电路用普通按键完成;软件利用C语言编程实现,单片机通过时钟芯片DS12C887获取时间数据,DS18B20采集温度信号送给单片机处理,然后通过LCD显示阳历年、月、日、时、秒、闹钟、星期、温度。Electronic perpetual calendar which is an application of the single-chip processor system, is combining by hardware and software. Hardware is composed of five modules： Main control unit, clock circuit, temperature test circuit, display circuit, keyboard interface. Main control module adopts AT89C52, clock circuit adopts the DS 12C887 clock chip, display module adopts the LCD, and temperature test adopts the DS 18B20 temperature sensor, keyboard interface circuit is completed by connecting ordinary button. Software takes language of C to program, Single-chip processor gets the time data through using the DS12C887 clock chip. The DS18B20 gathers temperature siguals and transmits them to single-chip processor. Lastly, the LCD displays solar calendar year, month, day, hour, minute, second, alarm clock, week and temperature.
