1、HUNAN UNIVERSITY数字电子技术课程设计报告设计课题：洗衣机控制电路设计学生姓名：王建平学生学号：专业班级：08级自动化1班学院名称：电气与信息工程学院 指导教师：叶佳卓一 课程设计的目的：1、能够全面巩固和应用“电子技术基础数字部分”课程中所学的基本理论和方法，并初步掌握小型数字系统设计的基本方法。2、掌握VHDL语言编制小型模块的方法，并采用层次化设计。3、培养电路设计能力，懂得理论设计与实物实现的有效结合。4、掌握Altium Designer软件的应用。二 总体方案分析及选择:洗衣机电路包含有总的控制模块,洗涤控制模块,洗涤记时模块,电动机控制模块以及LCD液晶板的动态显示
2、模块.经过分析后,我们把前四个模块进行组合,把他们合成一个模块即:总控制模块.他们之间的逻辑联结关系，是对数电课程的一个很好总结，也是自己对新知识（LCD液晶板的动态显示）学习理解运用能力的一个很好的提升机会。三 基本功能要求:1 要求设计制作一个普通功能洗衣机控制电路,使之能控制洗衣机的进水阀,排水阀,洗涤程序电机,甩干驱动装置等按预定程序工作.总体过程包括:进水 浸泡 洗涤 排水 甩干五个过程.进水从电路启动开始.其中浸泡可供选择,洗涤时间可以预置,洗涤结束时发出铃声进行提示并自动切断电源.发生故障如:缺水或进水超时 排水超时 甩干碰桶等时也可自动切断电源!2 根据洗衣机工作时不同的洗衣服
3、数量，我们设计了三个档（duoxi zhongxi shaoxi）来对洗衣机的进水 浸泡 洗涤 排水 甩干的五个过程分别预置时间。以此来区分洗衣机不同洗衣数量下的工作状态。3 用中小规模集成电路芯片或CPLD/FPGA设计符合上述任务要求的电路,并制作出能实际运行的装置.4 安装并调试电路,测试各部分电路功能或模型.5 演示并交验硬件装置.下载实现图:四 总控制模块的生成程序 library ieee;use ieee.std_logic_1164.all;use ieee.std_logic_arith.all;use ieee.std_logic_unsigned.all;entity w
