太阳能热水器控制系统的设计与研究

ABSTRACTAt present,the number of the world's population is increasing and the speed ofeconomic development is also increasing.At this time,there are more and more problemsin the field of energy:energy consumption,environmental pollution,and these problemsare gradually understood.At this time,"low-carbon life"has become a concern of people,gradually stepping into the vision of people in society.As we all know,solar energy is akind of renewable energy,which is inexhaustible all over the world.It is in line with theenvironmental protection problem and is basically not polluted.Based on this,China mustpay enough attention to solar energy technology and develop related industries.What weneed to see is that solar energy is a kind of energy with great market prospect.On this basis,the emergence of solar water heater not only meets the needs of the development of thetimes,but also makes people meet the needs of environmental protection,which is a greenand energy-saving product we should promote.This paper presents a new type of solar water heater based on the control systemmicrocontroller.This kind of solar water heater is different from the past.The centralprocessor selected in this design is AT89C51 single chip microcomputer,the display screenselected is 12864 dot matrix LCD,and the selected temperature sensing module isDS18B20 temperature sensing module.Through the above devices,time and water levelinformation can be set and displayed,and electric heating and other functions can becarried out in rainy days.By analyzing these information modules,the solar water heatercan provide hot water 24 hours a day.Key words:solar water heater,AT89C51,real-time clock,DS18B20,LCD screenII-
