摘 要:太阳能控制器以AT89S51单片机为监测控制核心,采用温度传感器、水位传感器实现温度和水位两种参数的实时显示,利用水位传感器、报警、给排水电路实现缺水报警、自动上水和管道排空的功能,并实现相应控制。
热水器智能控制系统的特点不仅是显示蓄水箱里水的水位和温度,而且具有当水位低于最低水位时系统会报警并自动给蓄水箱上水。当水位达到最高水位时系统会自动停止上水,冬季寒冷天气可以使管道排空防止管道损坏等特点。

Abstract: The solar water heater controller based on AT89S51 monitoring control of the core, with the temperature sensor, water level sensor temperature and water level of two parameters by using water level sensor, real-time display, alarm, water supply and drainage circuit alarm, automatic water supply and pipeline emptying function, and the realization of the corresponding control.
The water heater characteristics of intelligent control system is not only displayed in the water storage tank water level and temperature, but also when the water level below the lowest water level when the system will alarm and automatic water storage tank of water .when the water level reached the highest level , the system will automatically stop supplying water, cold winter weather can make the pipeline emptying pipe to prevent damage and so on.

本设计设计的太阳能控制器以AT89S51单片机为监测控制核心,采用温度传感器、水位检测电路实现温度和水位两种参数的实时显示,利用水位传感器、系统控制、给排水电路实现缺水报警、自动上水和管道排空的功能,并实现相应控制。使用到的各器件的具体用法将在下文一一说明。
功能上:按下系统启动开关,对水温和水位进行监控,数码管显示当前水温和水位,如果是最低水位,即0水位的时候,系统发出缺水警报,并自动上水,水位慢慢上升,当水位达到最高水位,即4水位时,断开给水开关,此时蓄水箱已满;需要排水时按下排水开关排水,水位慢慢下降,当降到最低水位,即0水位时,断开排水开关。
