Power management system and power management method
View Patent ↗There is provided a power management system including a detecting apparatus configured to detect electromagnetic waves generated in relation to an operation of an appliance and a receiving apparatus including an appliance determining unit configured to determine a type of the appliance based on a power spectrum of the electromagnetic waves, an operation determining unit configured to determine the operation of the appliance based on the power spectrum of the electromagnetic waves, and a power estimating unit configured to estimate power consumption of the appliance based on the type and operation of the appliance.
1. A power management system comprising:
a detecting apparatus having an antenna and a detecting unit, said antenna configured to wirelessly receive an electromagnetic signal emitted from an appliance during an operation thereof and said detecting unit configured to detect electromagnetic waves from the received electromagnetic signal; and
a receiving apparatus including an appliance determining unit configured to determine a type of the appliance based on a power spectrum of the electromagnetic waves, an operation determining unit configured to determine the operation of the appliance based on the power spectrum of the electromagnetic waves, and a power estimating unit configured to estimate power consumption of the appliance based on the type and operation of the appliance.
2. The power management system according to claim 1 , wherein the receiving apparatus includes a display unit configured to display the power consumption that is estimated.
3. The power management system according to claim 1 , wherein the receiving apparatus acquires information regarding the electromagnetic waves from the detecting apparatus through wireless or wired communication.
4. The power management system according to claim 1 , wherein the detected electromagnetic waves are electromagnetic waves generated by an electronic circuit of the appliance.
5. The power management system according to claim 1 , wherein the detected electromagnetic waves are electromagnetic waves generated by a remote controller that operates the appliance.
6. The power management system according to claim 1 , wherein the appliance determining unit analyzes the spectrum of the electromagnetic waves.
7. A power management method comprising:
wirelessly receiving an electromagnetic signal emitted from an appliance during an operation thereof and detecting electromagnetic waves from the received electromagnetic signal;
determining a type of the appliance based on a power spectrum of the electromagnetic waves;
determining the operation of the appliance based on the electromagnetic waves; and
estimating power consumption of the appliance based on the type and operation of the appliance.
