PAGE 时间管理基于单片机的时间控制器 摘 要 本设计详细介绍了利用AT89C51单片机设计时间控制器的方法。该时间控制器是以AT89C51单片机为核心，扩展一片XICOR公司的X5045组成的小系统，控制一路继电器：可以设定一天中的时间，设定继电器的开启时间和关闭时间，可以清除不需要的定时，能够紧急启动：所有的设定均通过键盘实现，按键具有连击功能，每个状态都有指示灯提示。我们设计的作息时间控制是用单片机实现的，是为了更好的对时间控制智能化。时间控制器包括硬件和软件。硬件部分包括继电器，存储器和显示器接口芯片。软件部分，主要是主程序设计。软硬件结合在一起，先调试子程序，然后逐级叠加调试，最后系统调试通过。时间控制系统可以准确的显示时间，在定时时间到时发出悦耳的铃声提醒同学们按时上下课。 关键词：单片机，控制，时间 Abstract This design USES AT89C51 is introduced time controller design method. The time controller based on AT89C51 single-chip microcomputer as the core, expanding a XICOR X5045 consisting of small systems, control relay all the way: you can set the time of day, set the relay open time and close time, timing, can remove don't need to start the emergency: all set by keyboard and buttons with functions of combo, each state has a light hint. Our design work and rest time control are implemented using single chip microcomputer, is intelligent in order to better control over time. Time controller includes hardware and software. Hardware part includes relay, storage and display interface chip. Software part, mainly is the main program design. Hardware and software together, debugging subroutine first, and then overlay debugging step by step, finally system debugging through. Time control system can accurately display the time in the regular time when a melodious bell remind students adding and dropping classes on time. 目录 1． 系统设计方案与论证……………………………………………………………………3 2．1设计要求…………………………………………………………………………………3 2．2系统设计总体方案…………………………………………………………………..….3 2　系统的硬件设计与实现………………..…………………………………………………4 2．1．1时钟芯片DS12887性能简介……………………………………………………….4 2．1．2时钟芯片读写时序……………………………………………………………….…6 2．1．3 时间寄存器地址……………………………………………………………………6 2．1．4 特殊控制寄存器功能………………………………………………………………7 2．2．1 液晶SYB12864介绍………………………………………………………………8 2．2．2 液晶与单片机的接口………………………………………………………………8 2．2．3 液晶写操作时序……………………………………………………………………9 2．3．1 红外发送与接收……………………………………………………………………10 2．3．2 遥控码数据分析……………………………………………………………………10 2．3．3 接收电路……………………………………………………………………………11 2．4．1电源部分电路图…………
