智能洗衣机控制系统的设计毕业的设计.doc

摘要 洗衣机是现代家庭必备电器之一。随着科学技术的发展，人工智能技术逐渐应用于家用电器中。人们对洗衣机的要求在不断地提高，传统的全自动洗衣机已经不能完全满足人们的需求。智能洗衣机应运而生。 本设计为基于模糊控制理论的微电脑程控式的智能洗衣机设计。应用模糊控制可以实现对洗涤过程中的水位和洗涤时间的合理控制。洗涤过程中，洗衣机能自动检测出布量和布质，自动地确定水位和洗涤时间，使衣物能够达到最佳的洗涤效果。 系统的硬件主要包括主控芯片，电源电路，驱动电路，传感器电路，显示电路，键盘输入电路等。由于本次设计采用了功能强大的AT89C52单片机为主控制芯片，因此系统具有控制能力强，硬件简单，工作可靠等优点。 关键词：AT89C52单片机；智能洗衣机；模糊控制 Abstract The washing machine is one of the essential electrical appliances of the modern family. With the development of science and technology， artificial intelligence technology is gradually applied in household appliances.As the requirements for washing machine is constantly improving， the traditional automatic washing machine can not meet the needs of people. Intelligent washing machines came to being. This paper describes the system design of microcomputer programmed intelligent washing machines based on the fuzzy control theory. The application of fuzzy control can reasonably control the water level and washing time in washing process. In the process of washing， Intelligent washing machine can automatically detect the amount of cloth and the type of fabric， automatically make sure water level and washing time， make clothings reach the best cleaning effect. System hardware mainly includes the main control chip， the power supply circuit， drive circuit， sensor circuit， display circuit， the keyboard input circuit， etc. Because it equipped with the powerful single chip micro-computer named AT89C52，this washing machine has many advantages over its strong controlling ability，simple hardware structure and so on. Key words : AT89C52 single chip; Intelligent washing machine;fuzzy control 目录 摘要 I Abstract II 1 绪论 1 1.1 洗衣机的发展状况概述 1 1.2 模糊控制理论简述 2 1.3 智能洗衣机的设计方案 3 2 系统概述 5 2.1 系统结构介绍 5 2.2 主要芯片及元器件介绍 6 3 系统硬件电路设计 15 3.1 系统电源电路 15 3.2 温度检测电路 15 3.3 水位检测电路 15 3.4 浊度检测电路 16 3.5 液晶显示电路 16 3.6 迅响电路 17 3.7 键盘输入电路 17 3.8 驱动电路 18 3.9 负载检测电路 18 4 系统软件设计 20 4.1
