基于单片机的智能热水器系统

AbstractWith the development of society and the improvement of people's livingstandards.People are increasingly demanding for the environment.Especially the environment,safety,intelligence,comfort and humanizedliving environment has become a new pursuit.The old way of life in thepast has been unable to meet people's current needs.With the developmentof science and technology,the development of various fields has becomerapid.In the field of home,technology has combined computer technology,network technology and electronic application technology,and smart homewas born.This report is about smart water heaters in smart homes.Thisdesign uses the product type is AT89C52 single chip computer.In the aspectof software and hardware,this design analyses whether the MCU can controlthe water heater to realize automation.In the aspect of hardware,theminimal system and its expansion,power supply design,various interfaces,digital-to-analog conversion circuit,water level and temperaturechecking circuit,safety protection circuit of MCU are introduced indetail.This report also describes in detail the performance andcharacteristics of the chips used,including,but not limited to,In theaspect of software design,assembly language is used to program.The mainreason for using assembly language is that it is easy to be recognizedby MCU,and the execution speed is relatively fast.Finally,the softwareis tested and analyzed.The design files of the intelligent water heaterare complete,the realization conditions are relatively relaxed,and thesoftware control is adopted.It can detect water temperature and waterlevel and realize intellectualization.Through safety design,thereliability and accuracy of the whole machine are also improved.Key words:SCM automatic control intelligent switch2
