毕业设计基于单片机的作息时间控制器摘 要校园作息时间控制系统主要用于学校, 对一些以 24 小时为周期的开关量进行自动控制。该控制系统是采纳 8031 单片机来实现对上述开关量的控制, 利用内部时钟来提供时钟信息, 设有六位数码管、 能够实时显示时间、 系统还设有输入键盘, 用以修改实时时钟, 体现了系统简单、 工作稳定可靠、 价廉、 控制时间精确及系统体积小等优点。关键词 作息时间控制 定时器 语音芯片 8031AbstractThe campus the daily timetable control system which is mainly used in the campus, it auto-control some switches which have periods of 24 hours. This control system carries out the switch parameter controls all above by SCM 8031 .It uses the Internal Clock to provide the clock information. It could show the real time with 6 bit digital tube. And it could modify the real time clock with the input keyboard. The system is simple, the running is steady and dependable, the controlled time is exact, and the physical volume of the system is small, all the advantages above can be incarnated in this system.Key words:THE DAILY TIMETABLE CONTROL,TIMER, DELAYED ACTION,8031目 录1 引言..................................................51.1 概述.............................................51.2 本文讨论内容.....................................52 作息时间控制器的整体设计..............................53 作息时间控制器的硬件设计..............................53.1 单片机芯片介绍...................................63.2 扩展电路.........................................73.2.1 程序存储器( 2764) ..........................73.2.2 数据存储器( 6264) ..........................83.2.3 扩展电路部分接线............................93.3 键盘显示电路....................................103.4 音乐播放电路....................................123.5 复位电路........................................143.6 晶振电路........................................153.7 电源电路..................
