摘要
随着科技的快速发展,人们对时间的观察,从原始的观测太阳到摆钟再到如今的电子钟,不断创新纪录。本次设计的电子万年历系统采用AT89S52单片机为控制核心,能够显示从2000至2099年的年、月、日、星期、时、分、秒并进行整点报时。同时还可显示一年中的公历节日并对当前环境温度进行实时测量。系统具有读取方便、显示直观、功能多样、电路简洁、成本低廉等诸多优点,符合电子仪器仪表的发展趋势,具有广阔的市场前景。
关键词:单片机;多功能万年历。
ABSTRACT
Along with technical fast development, the people to the time observation, from primitive observed the sun to pendulum clock until now electron clock, innovated unceasingly the record. This design's electronic ten thousand calendar system uses at89S52 monolithic integrated circuit is the control core, can demonstrate from 2000 to 2099 year, month, Japan, week, divides, the second and carries on the integral point to report time. Simultaneously may also demonstrate that one year the solar calendar holiday and carries on the real-time measurement to the current ambient temperature. The system has the read to be convenient, the demonstration is direct-viewing, the function is diverse, the electric circuit is inct, cost inexpensive and so on many merits, conforms to the electronic instrumentation measuring appliance's trend of development, has the broad market prospect.
KEY WORDS: monolithic integrated circuit; multi-purpose ten thousand calendars.
