摘要
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。其中,电热水器控制器性能的好坏不仅是电热水器性能好坏的体现,更关系到人身安全等重要内容。因此,电热水器控制器的设计是智能电热水器的需要,同时也是电热水器的重要组成部分。
论文首先结合当前电热水器的发展现状和发展趋势,介绍了电热水器控制器研究的目的及意义。在确定控制参数的基础上,详细介绍了控制器的各功能组成模块及工作原理。根据电热水器工作原理进行控制器的硬件电路设计和软件设计。最后深入介绍了控制器的调试方法和过程,以及对整个控制器的设计与实现工作进行总结。硬件电路设计中充分利用51单片机的特点,主要对水温控制、水位控制和漏电检测模块进行了详细地分析设计。其中,通过采用自制分段式水位传感器,实现了水位测量的低成本设计;对水温控制进行了完整的理论分析和算法设计,测量精度达到±1℃;通过分析漏电检测原理,在理论计算基础上设计了漏电检测电路。软件部分在硬件平台的基础上实现电热水器的控制工作,包括液晶显示程序、按键扫描程序、水位控制程序、温度控制程序、漏电检测程序以及声音提示程序等。
本系统在软硬件设计的基础上,使用了计算机仿真演示。通过计算机仿真,该控制器可以实现对水位控制、温度控制等功能,并能动态监测电热水器工作状况,这也验证了此设计的正确性。

Abstract
With the improvement of quality of people's lives, people’s demand for water heaters tend to be more intelligent and digital. Among them, whether the electric water heater controller performance is good or not is not only the embodiment of the water heater performance, but also related to personal safety and other important content. Therefore, the electric water heater controller design is not only the need of intelligent water heater; but also is an important part of electric water heater.
Firstly with the electric water heaters’ current development situation and trend, the purpose and significance of the electric water heater controller was introduced in this paper. Based on determining the control parameters, the ponent and the working principle of the controller were introduced in detail. The controller hardware and software were designed by knowing the working principle of the water heaters. Finally, the paper described the debugging process and method in detail, the design and implementation of the control system also was summarized. Full use of features 51MCU in hardware design, mainly analysis the water temperature control, water control and leakage detection module in detail .Among them, the water temperature control for plete theoretical analy
