Title:
SMART TAP
Document Type and Number:
Japanese Patent JP2016028545
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a smart tap which identifies household electrical appliances connected by a power plug on the basis of, e.g., a result of measuring a power waveform of each of a plurality of electric appliances at the time of energization of the electric appliances, grasps the operation states of the household electrical appliances to detect an abnormal operation, and controls an EoD system.SOLUTION: A smart tap includes voltage waveform measurement means, current waveform measurement means, radio communication means including an antenna, control means, and an arithmetic unit. The voltage waveform measurement means and the current waveform measurement means measure a voltage waveform and a current waveform of power supplied to each of one or more household electrical appliances via a corresponding one of respective power plugs connected to the household electrical appliances. The radio communication means 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. The control means controls switching of the power supplied to the household electrical appliances and the amount of the supplied power in accordance with the control signal.SELECTED DRAWING: Figure 4
