xx工业应用技术学院本科生毕业设计（论文）题目：智能热水器系统设计起止日期：2016年3月6日至3月10日指导教师：职称：学生姓名：学号：专业：院（系）：教研室主任：20 年月日审查院系负责人：20 年月日批准摘要在智能热水器系统控制设计中，采用采用STC89C51单片机作为核心单元，本文对智能热水器如何实现智能化控制做了有效性分析，利用各种原件，例如：感器温度传感器、继电器来完成论文的设计。

通过硬件设计和软件设计两个方面对智能热水器执行控制。

在软件设计方面，采用C语言来进行编程,在硬件设计方面通过键盘显示、接口、温度控制报警电路、电源电路、水温检测电路来构成整个单片机的控制系统，这些功能的实现主要通过对单片机最小系统进行扩展来实现。

在设计方面，通过比较分析，采用最好的方案，力求设计简单易行，能够进行用软件来控制，完成水温的测试，能够进行智能加热，提高了系统设计的准确性和可靠性。

The single-chip microcomputer integrates the various components in a chip, uses the internal bus structure, reduces the connection in different chips, enhanced greatly the reliability and anti-jamming capability. In the development of single-chip microcomputer, due to its excellent cost performance, high integration, small size, high reliability, it has been used as a control center all the time.Since the birth of single-chip microcomputer, it began to walk into a human’s life, such as washing machines, refrigerators, electronic toys, DMB, which equipped with the single-chip microcomputer, and improved their intelligence, ability. People, who used them, will love them better. The single-chip microcomputer makes human’s life more convenient, comfortable and colorful. As a result, I use single-chip microcomputer to design intelligent electric water heaters.This paper mainly discusses the intelligent electric water heater how to work. To achieve system goals, in deep analysis of the STC89C51, I made a set of simple and practical control system design. The system is mainly to use single-chip microcomputer to control centers, with specific hardware architecture and the corresponding software design, thus the intelligence of the water heater would become true.Keywords: single-chip microcomputer, controller, intelligence, water heater, design目录主要符号表第1章绪论 ·······················································································1.1 选题的背景、目的及意义 ·······························································1.2 国内外的研究状况和成果 ·······························································1.3 研究设想和实验设计 ·····································································第2章硬件系统设计 ·········································································2.1 方案验证 ····················································································2.2 硬件系统设计 ··············································································2.2.1 电源电路 ···········································································2.2.2 键盘/显示接口电路······························································2.2.5 报警电路 ···········································································2.2.6 模数转换电路 ·····································································2.2.7 温度检测电路 ·····································································2.2.8 水位检测电路 ·····································································2.2.9 STC89C51功能及特性介绍 ·····················································第3章软件系统设计 ·········································································3.1 主程序流程框图 ·····································································结论······································································································参考文献 ······························································································致谢······································································································第1章绪论1.1 选题的背景、目的及意义随着人们生活水平的提高，越来越多的智能热水器走进了每个家庭，这种热水器使用起来比较方便，逐渐代替了燃气热水器，能热水器的市场份额已经超过了80%，随着新能源的发展，太阳能智能热水器因为安装的局限性，还没有得到普及，对我国城镇居民中，人们在使用智能热水器的时候，非常注重产品的安全，环保，随着家电的普及，人们悠闲选择，电热水器和太阳能热水器，因为燃气热水器对环境会造成污染，随着国家对环保的重视，智能热水器在人们日常生活中所占的比例越来越大，在这种市场需求下，我们开发出了智能热水器，利用单片机来进行系统控制设计，使得人们在使用的时候非常方便安全。
