Along with the people living standard enhancement, each kind of water heater use quite popularized.One after another is also published with it necessary control meter.However, in the market each kind of water heater control circuit also with ideally requests to be far from at present.The consumer needs truely “automatic” the control, realizes the use to simplify.On the home use television, the electric refrigerator were likely same, put through the power source, the hypothesis finished do not need to worry again.
This graduation project has designed one kind of automatic circuit using at89C51 monolithic integrated circuit, this electric circuit used in the solar water heater, could realize when the water used, if the date exposed to the sun the water temperature not to be able to achieve the setting value, then the electric heating made up automatically heats.Thus has realized the water heater automatic and the energy conservation.This article introduced in detail based on the monolithic integrated circuit solar-powered water heater automatic control system composition, the hardware design.Has realized the temperature and the water level parameter real time display, when has the temperature hypothesis, the water level hypothesis and the control function, after the power cut comes the electricity again does not need to establish, has the breakdown to report to the police with the breakdown from the processing function, good stability and resistance to interference.
This article in detail introduced this control system hardware design process and the software, the hardware debugging process.
