中文摘要：

现有的家用电热水器主要分为连续水流式和贮水式,前者加热快但功率要求很高,后者功率低但加热时间长、可靠性差。针对该问题设计了一种基于单片机的智能电热水器控制系统。系统在家用贮水式电热水器上进行改进,根据设置的水温和水位值自动控制加热器和进水阀工作,具有人机交互、水位控制、温度控制、漏电保护及声音报警等功能,以及操作方便、安全可靠、节能环保等优点。

英文摘要：

The existing home electric water heater is mainly divided into continuous flow and water storage type. The former is fast but the power requirement is high; the latter has low power but long heating time and poor reliability. Aiming at this problem,an intelligent electric water heater control system based on single chip microcomputer is designed.The system is improved in the household water storage type electric water heater. According to the set of water temperature and water level value,the heater and water valve work is automatically controlled. It has functions such as man-machine interaction,water level control,temperature control,leakage protection,sound alarm,and etc. Also it has advantages of easy operation,safety,reliability,energy saving and environmental protection.
