Abstract The paper introduces designing process and designing plan of the family power management system which is based on Single-Chip Microcomputer. There are two functions in this system. First it can measure the temperature of water in the fixed time which is designed by user and it will compare the measured temperature with designed temperature. If the measured temperature is lower than designed temperature, the system will not stop providing the power to domestic water heater until the measured temperature is not lower than designed temperature. If the measured temperature is not lower than designed temperature, the system will not function. Second it can control power of refrigerator. When real time is in the fixed time, single-chip microcomputer will control relay to close. And it will continue closing for half an hour.
Due to functions above, users can make the system function during the time of valley electricity by designing functioning time to save money and resource.
