The Design of Electronic Calendar

摘 要

随着当今世界经济的快速发展和信息化时代的来临，各种各样的小型智能家电产品陆续出现在我们的生活当中。日历是人们不可或缺的日常用品。但一般日历都为纸制用品，使用不便，寿命不长。电子万年历采用智能电子控制和显示技术，改善了纸制日历的缺陷。本设计以AT89S52单片机为核心，构成单片机控制电路，结合DS1302时钟芯片和24C02 FLASH存储器，完成时间的自动调整和掉电保护，全部信息用液晶显示。52单片机万年历程序52单片机万年历程序时间、日期调整由三个按键来实现，并可对闹铃开关进行设置。日历能显示阳历和阴历年、月、日以及星期、时、分、秒。在显示阴历月份时，能标明是否闰月。

ABSTRACT

With the rapid development of world economy and the forthcoming of information era, many kinds of mini-type intelligent domestic electric appliances appear in our life one after another. Calendars are necessary daily goods in people’s life. But they are generally paper goods with inconvenient use and short life. Electronic calendar adopts the technology of intelligent electronic control and display, and then improves the deficiency of paper calendars. The design adopts the core of AT89S52 single chip microcomputer, which constitutes controlling circuit, and integrates DS1302 clock chip and 24C02 FLASH memory, which achieve self-adjusting of time and no power protecting. LCD displays all information. Time and date adjusting is carried out by three keys, which can also set the alarm clock. The calendar can display solar and lunar year, month, day, week, hour, minute, second. When displaying lunar months, leap month is showed.

Key Words： electronic calendar ；52 series single chip microcomputer ； clock chip； flash memory ； LCD
