毕业论文（设计）rocontroller as the core to design the Smart electric water heater. The design of intelligent MCU control the possibility of electric water heaters were analyzed using temperature sensors, water level detection device, and the ADC, etc. to complete the design. In the hardware design, the main system and its extension to the microcontroller, power supply circuit, keyboard, display and interface circuits, analog to digital conversion circuit, the water level and water temperature detection circuit, alarm circuit is described in detail. It also details the design applied to the main chip in the performance and features, including AT89C51, DS18B20, ADC0809 and so on. In software design, the use of assembly language programming, microcontroller because of its easy for the identification, execution speed. Finally, the error analysis software debugging.
The Smart electric water heater designed to achieve the program is simple. To control the use of software design, can detect the water level and water temperature smart, intelligent heating, and improve the overall reliability and accuracy, simple, low cost, safe and practical features, consistent with residential, office water requirements, with the promotion of Value.
Keywords: Intelligent temperature control, home water heaters, MCU, LCD display.

第一章 绪论
随着人们生活水平的提高，热水器在人们的生活中扮演着越来越重要的角色，越来越受到人们的青睐。由于燃气热水器易受水压限制，而且安全性较差。每年使用燃气热水器造成的爆炸、中毒等事故也屡有所闻。消费者对燃气热水器怀有一定的惧怕感，所以燃气热水器渐渐淡出市场。而智能电热水器越来越受到人们的认可。
电热水器在中国的历史已经有10多年了，期间也经历了数次起落的过程，在上个世纪的最后几年，随着国外品牌的进入和国内一些大家电厂的目光转向电热水器，智能储水式电热水器能适应任何天气变化，普通家庭可直接安装使用，长时间通电可以大流量供热水。使用时不产生废气，既安全又卫生。目前市场上销售的电热水器多数还带有防触电装置。干净卫生，不必分室安装，调温方便。在电热水器发展到如今的水平，已经可以基本满足生产生活中的需求。但为求精益求精，当今学者将目光放在了更好的调节控制水温水位上，尽可能得使其更智能化，能够做到更加的安全稳定舒适。我国在对电热水器水温水位系统的研究已取得很大的成就，并在不断地完善之
