洗衣机变频调速控制器设计.doc

摘 要 洗衣机是人们必备日常生活家电，其发明与普及改变了人们的劳动理念。传统的洗衣机仅仅局限于洗衣以及脱水等基本功能，而新型的洗衣机则注入很多新型的元素，智能化控制技术的引入，使得洗衣机更加人性化，对于劳动者而言，智能化洗衣机不仅仅提高了劳动效率，而且增加了人们的生活乐趣。一个功能完善的洗衣机，不仅仅只局限于洗衣脱水等功能，还能够按照用户的要求实现更多智能化的要求，除此之外还可以对洗衣机的故障状态进行检测，及时对洗衣机的故障状态进行保护，保证洗衣过程的安全可靠运行。 本文首先介绍了洗衣机的研究背景以及目前国内外的发展趋势，对洗衣机的工作原理进行了深入的剖析，分别从硬件设计以及软件设计两方面对洗衣机进行了设计，由软件驱动硬件的方法来实现了洗衣机控制系统的实现。本次设计以AT89C51单片机为控制核心，在此基础上增设有一定的外围电路，例如时钟电路、复位电路、键盘电路、显示电路、电机驱动电路以及指示灯电路，利用Protues仿真软件实现洗衣机的功能模块如下变频调速模块、故障处理、水位检测、洗涤过程等洗衣机主要基本功能。最后通过硬件以及软件调试，得到了较为完善的洗衣机控制系统，满足了本次设计任务书的基本要求。 关键词：洗衣机；AT89C51；控制系统；Protues仿真  Abstract Washing machines are an essential daily lives of people appliances, its invention and popularization of the concept of changing the way people work . General digital logic circuits controlled by only two or three procedures a washing machine , there are also a fool by -pass procedure . The microcontroller-based control of a washing machine can be a complex process control , water level segment will refine , refine rinsing function , coupled with the application of different clothing and other functions, the washing process is greatly increased. For a fully automatic washing machine , the first requirement to complete the basic functions of laundry ; while also setting several different washing programs according to the different needs of users ; should also consider the strength of the flow of decisions washing conditions ; Also on laundry fault diagnosis process appears to ensure high-speed operation and so on. This paper describes the current situation of the domestic washing machine control systems , the problem facing the development . Gap washer machine from product quality, performance and application perspective ; domestic washer machine industry as a whole to see the problems as well as its development trend. Using AT89C51 microcontroller as the master chip washing machine control systems , washing laundry program runs under MCU control , the main functions of the module are as foll
