There is provided a smart tap into which one or more than one power plugs can be inserted, including a voltage waveform measurement unit, a current waveform measurement unit, a communication unit, a control unit, and an arithmetic unit, wherein the voltage waveform measurement unit and the current waveform measurement unit are units which measure a voltage waveform and a current waveform of power supplied to each of one or more home appliances via a corresponding one of respective power plugs connected to the home appliances and the communication unit is a unit which transmits the voltage waveform and the current waveform or a result of processing of the waveforms to a server which is installed in a place separate from the smart tap and receives a control signal based on a result of computation in the server, and the control unit is a unit which controls switching of the power supplied to the home appliance and the amount of the supplied power in accordance with the control signal. The smart tap identifies a household electrical appliance connected by a power plug on the basis of, e.g., a result of measuring power waveforms of a plurality of electric appliances at the time of energization of the electric appliances. The smart tap measures and calculates the amounts of power requested by the household electrical appliances, grasps the operation statuses of the electric appliances to detect abnormal operation, and controls an EoD system. |
