The single-chip microcomputer integrates the various components in a chip, uses the internal bus structure, reduces the connection in different chips, enhanced greatly the reliability and anti-jamming capability. In the development of single-chip microcomputer, due to its excellent cost performance, high integration, small size, high reliability, it has been used as a control center all the time. Since the birth of single-chip microcomputer, it began to walk into a human’s life, such as washing machines, refrigerators, electronic toys, DMB, which equipped with the single-chip microcomputer, and improved their intelligence, ability. People, who used them, will love them better. The single-chip microcomputer makes human’s life more convenient, comfortable and colorful. As a result, I use single-chip microcomputer to design intelligent electric water heaters. This paper mainly discusses the intelligent electric water heater how to work. To achieve system goals, in deep analysis of the STC89C51, I made a set of simple and practical control system design. The system is mainly to use single-chip microcomputer to control centers, with specific hardware architecture and the corresponding software design, thus the intelligence of the water heater would bec
