摘　　要：提出了一种基于单片机的太阳能热水器出水恒温控制系统。系统以AT89C2051单片机为核心,根据用户的设定温度和测得的出水口温度,以脉冲宽度调制方式调整冷热水的进水阀门,使得出水温度在冷、热水温度或压力发生变化时也能保持基本恒定。实验表明:系统结构简单有效,调节稳定快速。A water temperature control system for solar heater based on a micro control unit（MCU） is developed.The micro control chip AT89C2051 is used to measure the temperature of output water,and compare it with the temperature value set by the user.The system then adjusts the on-off state periods of the solenoid valves for hot and cold water.The temperature of output water remains constant regardless of the varied input water temperature and water pressure.Experiments show that the system structure is simple and effective,and it works stably and responds quickly.
