摘 要
电热水器是一种可供浴室、洗手间及厨房使用的家用电器，市场上传统的机械式电热水器控制精度低、可靠性差，随着人们生活质量的提高，人们对电热水器的要求越来越趋向于智能化和数字化，来自市场和业内人士的信息表明:方便化、安全化、中央化、小型化将是热水器未来发展的趋势。本次设计介绍了用单片机构成电热水器控制器的基本方法。利用AT89C系列单片机可构成一功能较为完善的电热水器控制器,控制器的设计可按总体方案、硬件设计、软件设计、调试、固化五个步骤进行。其硬件系统由输入、单片机和输出三大部分组成;软件系统的设计采用模块化结构,主要由主程序、中断服务程序和若干功能模块子程序组成。通过单片机定时推断出加热时间的提前量在一定程度上实现了节电功能和避免了等用热水情况的出现。

Abstract
The electric boiler is one which may supply the bathroom, the washroom and the kitchen using domestic electric appliances, in the market the traditional mechanical electric boiler control precision low, the reliability is bad, with people quality of life enhancement, the people more and more tend to the electric boiler request the intellectualization and the digitization, comes from the market and professional’s information indicated: The convenience, the security, the central committee and the miniaturization will be tendencies which the water heater will be developed in future. This design introduced constitutes the electric boiler controller essential method with the monolithic integrated circuit. May constitute a function more perfect electric boiler controller using AT89C series monolithic integrated circuit, the controller design may accord to the overall concept, the hardware design, the software design, the debugging, solidify five steps to carry on. Its hardware system by the input, the monolithic integrated circuit and outputs major part three is composed; The software system design uses the modular structure, mainly by the master routine, the interrupt service and certain function module subroutine is composed. Fixed time inferred the heating time through the monolithic integrated circuit the lead to realize the electricity saving function to a certain extent and to avoid urgently needing the hot water situation on the appearance.
