Abstract
The electric boiler is one which may supply the bathroom, the washroom and the kitchen using domestic electric appliances, in the market the traditional mechanical electric boiler control precision low, the reliability is bad, with people quality of life enhancement, the people more and more tend to the electric boiler request the intellectualization and the digitization, comes from the market and professional's information indicated: The convenience, the security, the central committee and the miniaturization will be tendencies which the water heater will be developed in future. This design introduced constitutes the electric boiler controller essential method with the monolithic integrated circuit. May constitute a function more perfect electric boiler controller using AT89C series monolithic integrated circuit, the controller design may accord to the overall concept, the hardware design, the software design, the debugging, solidify five steps to carry on. Its hardware system by the input, the monolithic integrated circuit and outputs major part three is composed; The software system design uses the modular structure, mainly by the master routine, the interrupt service and certain function module subroutine is composed. Fixed time inferred the heating time through the monolithic integrated circuit the lead to realize the electricity saving function to a certain extent and to avoid urgently needing the hot water situation on the appearance.
