The in tellige nt water heater con trol
system based on 51 sin gle chip
microcomputer
Abstract
With the progress of scie nee and tech no logy and the con ti nu ous
improvement of people's living standard, the water heater is more and more widely
into the thousands, has brought great convenience to people's the same time,
people also hope that the water heater is not just simply by switch or butt on comma
nds,to heat water, also can accord ing to the people set the temperature of the
automatic constant temperature, timing,
heating, automatic judgment function such as water level, the water heater of
intelligence and security are put forward higher requires a water heater has a in
tellige nt con trol system, can automatically access to curre nt in formatio n, water
temperature and water level determ ine the actual temperature and the preset
temperature relations, so as to realize the automatic con trol of heati ng.
This paper puts forward a kind of in tellige nt water heater con trol system
based on 51 single chip solution, the schemeadopts DS18B20single line digital
temperature sensor to test the water temperature, using DS1302clock chip realize
counting and timing functions, at the sametime
joined the water judgment and alarm user through the buttons and screen to
complete the system parameter setti ng, so as to realize the fun ctio n such as tim
ing, automatic con sta nt temperature heati ng.
