摘　　要：以STC89C52单片机为主控芯片,设计了节能饮水机控制系统。通过两个DS18B20温度探头将热水和温水水温实时送入STC89C52单片机,并采用液晶显示器LCD1602显示当前热水和温水水温,以及温水水温的设定值上限和下限。当热水烧好后,通过继电器自动控制加热器关闭并语音提醒人们热水可以饮用。当温水准备好后,通过继电器自动关闭温水池和热水池之间的电磁阀,以及温水池的进水电磁阀,并语音提醒人们温水可以饮用,避免了热水反复加热,温水水温数据误差在0.3℃以内,可以满足不同使用者对温水水温的需求。该饮水机节能,使用安全方便成本低,可以随时为人们提供热水、温水、凉水,而且具有温水水温设置等功能。In order to provide convenience for people＇s lives, save energy sources, economical utilization of electric pow- er, design of a control system of energy saving drinking machine based on STC89C52 microcontroller. The hot water and warm water temperature data collected from two temperature probe DS18B20 real-time sent to STC89C52 microcon- troller, and display current hot water temperature, warm water temperature, upper and lower warm water temperature limit using LCD1602. When the water is boiling, the system could automatically close heater through relay and language warning people that hot water can be drunk. When the warm water temperature is suitable, the system could automati- cally close the electromagnetic valve between warm water pool and hot water pool, and could automatically close the elec- tromagnetic valve of warm water pool through relay and language warning people that warm water can be drunk, avoid the hot water is heated repeatedly, the warm water temperature data error in 0.3℃, meet various requirements of users. The drinking machine is energy saving, the operation is secure and convenient and low cost. The system not only can provide hot water, warm water, and pure water, but also have the function of water temperature setting of warm water, etc.
