基于51系列单片机的多路定时唤醒仪设计论文

基 于 51 系 列 单 片 机 的 多 路 定 时 唤 醒 仪 设 计摘 要时钟是人们生活和生产必不可少的一种工具，尤其在现在讲究效率的年代，更需要时常提醒人们时间。因此，设计一种多路定时唤醒仪也显得十分有意义。本文设计了一款能显示时钟、校对时钟、并且带有三路定时报警的数字时钟。本文对当前电子钟的开发手段进行了比较和分析，最终确定了采纳单片机技术实现多路定时唤醒仪。本设计应用AT89C52芯片作为核心控制器，使用DS1302 实时时钟日历芯片完成时钟的基本功能。另外，本设计还包含6位LED数码管显示模块，键盘模块以及单片机基本应用电路。这种实现方法的优点是电路简单，性能可靠，实时性好，时间精度高，操作简单，编程容易。该唤醒仪可以应用于一般的生活和工作中，也可通过改装，提高性能，增加新功能，从而给人们的生活和工作带来更多的方便。关键词：电子时钟；多路定时；AT89C52 ；DS1302 ；唤醒仪 The Design of Multi-channel wake-up clock based on MCS-51 AbstractClock, as a tool, is essential to people's lives and production. Particularly in the current era of efficient, it is necessary to remind people the time. Therefore, the design of a multi-channel clock is very meaningful. The paper designs a clock can not only display time, proofread time, but also can wake up by multi-channel.Comparing and analysising the development technology of the electron clock, the design determines to use the MCU technology to realize the multi-channel wake-up clock. This design utilizes AT89C52 as a core chip and uses DS1302 real-time clock chip to complete the basic function of the clock. In addition, the design also includes six LED digital display module, the keyboard module, as well as the basic application of single-chip circuit. The method has the advantage of being simple circuit, reliable performance, good real-time, high precision of the time, simply operation, easy programming. The multi-channel wake-up clock can be applied to the general liv...
