| Summary: | In this paper, it takes ionator HOM as prototype, and puts forward innovative to research and develop a kind of ionized water decontamination and disinfection device based on single chip microcomputer control to replace the chemical detergent and disinfectant used in daily life. In system design, it adopts modular design program, takes single chip microcomputer as the core of control, and determines the schematic diagram of control of function module. In software system design, it gives independent software design to the function module according to the functional requirements realized by software, provides the block diagram of program flow, and conducts debugging and performance test by replacing the circuit board in ionator HOM with the designed circuit board of control system. It is indicated by the debugging that circuit board can work well and control generation of the needed electric signal. Simultaneously, it is known from performance test that the designed circuit board can control ionator HOM effectively and has certain germ killing efficacy.
