基于51单片机的智能热水器控制系统
摘 要
随着科技的进步和人们生活水平的不断提高，热水器越来越普遍地走进千家万户，给人们的生活带来了极大的方便。同时，人们对热水器的智能化和安全性都提出了更高的要求。这就要求热水器具有一个智能控制系统，能够自动获取当前水温和水位信息，判断实际温度与预设温度关系，从而实现加热的自动控制。
本文提出了一种基于51单片机的智能热水器控制系统的解决方案，该方案采用DS18B20单线数字温度传感器来对水温进行检测，使用DS1302时钟芯片实现计数和定时功能，同时加入了水位判断和报警设计。用户通过按键和显示屏来完成系统的参数设置，从而实现定时加热、自动恒温等功能。

The intelligent water heater control system based on 51 single chip microcomputer
Abstract
With the progress of science and technology and the continuous improvement of people's living standard, the water heater is more and more widely into the thousands, has brought great convenience to people's the same time, people also hope that the water heater is not just simply by switch or button commands, to heat water, also can according to the people set the temperature of the automatic constant temperature, timing, heating, automatic judgment function such as water level, the water heater of intelligence and security are put forward higher requires a water heater has a intelligent control system, can automatically access to current information, water temperature and water level determine the actual temperature and the preset temperature relations, so as to realize the automatic control of heating.
This paper puts forward a kind of intelligent water heater control system based on 51 single chip solution, the scheme adopts DS18B20 single line digital temperature sensor to test the water temperature, using DS1302 clock chip realize counting and timing functions, at the same time joined the water judgment and alarm user through the buttons and screen to complete the system parameter setting, so as to realize the function such as timing, automatic constant temperature heating.
