摘　　要：基于STC89C52设计一款具有时间、星期、年月日和温度显示的万年历,主要由DSl302实现时分秒、年月日和星期的计时功能,DS18B20实现温度采集功能,该万年历除复位按键外,还设置有4个按键,可以对时间进行"加""减"设置,同时还具备定时功能,定时时间到则蜂鸣器报警,在LCDl602液晶屏上进行实时显示,实现人机交互。利用Keil软件编写C程序,通过Proteus仿真以减少焊接盲目性,最后进行实物电路制作,实现设计、仿真与制作的一体化,具有理论与实践结合的现实意义。Based on STC89C52, the paper designs a permanent calendar system which can display time, date, week and temper- ature. DS1302 is a kind of permanent calendar chip that can reckon time,including of seconds, minutes, hours, year, month, day week and so on. Besides, the DS18B20 has the function of temperature acquisition. There are four buttons in the perma nent calendar system besides the reset button, one could add or subtract time, set alarm and buzzer warning by operating the buttons. All the phenomena can be real-time displayed and achieved human-computer interaction function via the LCD 1602. The author has written the C program by using the Keil software, simulated circuit diagram to reduce the blindness of welding by Proteus, and made physical circuit realize the integration of design, simulation and production. The design realizes the com- bination of theory and practice of practical significance.
