数字电路课程设计：洗衣机控制器的设计

08电气8班 彭亮 学号:20081610612课程设计报告学生姓名： 彭亮组成员：郑淑芳 吴俊 刘靖 彭亮 专业班级：08级电自8班学 号： 20081610612时 间：2010年12月20日课题:洗衣机控制器的设计功能:1按内定标准洗涤时间洗涤，脱水时间脱水； 2有预约洗衣功能，如：你预约1小时，则系统会在1小时后自动进入洗涤状态； 3显示屏上能实时显示该机正处于何种状态和该状态下的时间； 4为该机设置了报警提示，及报警铃声控制时间； 5可以自己设定洗涤及脱水的时间； 6可以用于直接脱水； 7报警显示；模块分析:根据系统的设计要求，整个系统可分为键盘转按键，洗衣机主控制器，LCD三个模块。各个模块的作用如下： 1键盘转按键：将板上键盘变为16个按键，从左上到右下，按键按下时，对应输出为1，松开为0 ，它用于洗衣机外端口的输入； 2洗衣机主控制器：它是整个系统正常有序工作的核心，按设计要求产生相应的控制逻辑，以控制其他各部分的协调工作； 3LCD：在LCD上按格式显示4组两位数码 D0D3 从左至右，它用于显示功能中要显示的信息；设计要求1.分析设计任务，拟定多种设计方案，根据当时的制作条件，选定适合的方案绘制框图和设计流程。2.设计各部分单元电路或编写VHDL描述程序。3.对制作的电路进行功能测试，分析各项技术指标；或对设计的电路进行功能仿真，分析仿真波形。4.总结设计资料，但因包括原理电路、VHDL描述、仿真波形的设计报告，校验并演示电路装置。设计过程： 根据上述功能及要显示的信息，我们分析得出10个状态，分别为s0(复位即等待命令，输入)，s1（输入命令），s2(注水)，s3(洗涤)，s4(排水)，s5(漂洗)，s6(脱水)，s7(报警响铃计时)，s8（预约计时），s9(结束，播放提示音计时)。相关模块的程序：1主控系统：LIBRARY IEEE;USE IEEE.STD_LOGIC_1164.ALL;USE IEEE.STD_LOGIC_UNSIGNED.ALL;entity xiyiji is port (CPIN,R : IN STD_LOGIC;
