5、进一步深化和巩固所学基础理论、专业知识及实验技能，提高学生的技术应用能力，使学生了解和掌握单片机应用系统的软、硬件设计过程、方法及实现，为以后设计和实现单片机应用系统打下良好基础。二、系统结构框图与工作原理2.1 设计示意图 单片机AT89C51LCD显示模块声音模块调节模块图2-1 系统电路框图以单片机为核心，设计一个智能化作息时间控制器。该控制器要求的功能有：按本校作息时间接通/断开电铃；并用12864液晶屏的第一行显示本人的姓名和学号，第二行显示实时时钟。作息时间控制器用于学校教学楼的时间控制，利用单片机内部定时器实现时间基准定时，显示的内容要求有时、分、秒各两位，并能调节小时和分钟。2
6、.2 单片机核心控制模块采用AT89C51，它具有Flash ROM，内部具有4KB ROM 存储空间，能于3V的超低压工作，而且与MCS-51系列单片机完全兼容。2.3 LCD液晶显示模块LCD12864为128*64点阵型液晶显示模块，可显示各种字符及图形，可与CPU直接接口，具有8位标准数据总线、6条控制线及电源线，采用KS0107控制IC。该模块包括的函数为LCD_inti()/LCD 的初始化、checkbusy()/检查LCD是否忙碌、 writecode()/写命令、 writedata()/写数据、hanzi()/显示汉字、 zifu()/显示数字或字符。2.4 声音模块电路板
7、上的主控模块直接接一个蜂鸣器，构成一个简单的音响电路，该电路利用单片机的一个引脚作为音源，一个引脚接高电平，导通时，蜂鸣器发声，比一个引脚接地时候的声音要大些。脉冲信号的频率决定了其发出声音的音调。该模块比较简单，其函数为void s_fmq()/蜂鸣器叫 、nling()/判断是否闹铃。2.5 调节模块该模块要实现6个模式的调节和转变。调节模式的实现只用了三个按钮，分别是Mode 、Inc和Dec按钮。图2-2 电路原理图三、软件设计与说明开始作息时间控制子程序比较时、分、秒参数送12864初始化程序是闹铃响10s12864初始化到“8：00”？否读、写日期和时间到“8：45”？闹铃响10s
