Abstract
An outlet device (100) used in the power consumption measurement system of the invention comprises: a feeding unit (101) to which a load (50) in a consumer system is connected and which feeds electricity to the connected load; a sensor circuit (110) for detecting a current amount flowing from the feeding unit (101) to the load (50); and a power consumption amount measuring unit (121) for measuring the power amount consumed by the load (50) on the basis of the current amount detected by the sensor circuit (110).
Claims10
A power consumption measurement system, comprising:
- an outlet device provided in a consumer;
- and
- a measurement unit configured to measure the amount of power consumption associated with the consumer, wherein
- the outlet device comprises:
- a feeding unit, connected to a load within the consumer, configured to supply power to the connected load;
- and
- a detection unit configured to detect the amount of electric current flowing from the feeding unit to the load, and
- the measurement unit measures the amount of power consumption of each load depending on the amount of electric current detected by the detection unit.
An outlet device provided in a consumer, comprising:
- a feeding unit, connected to a load within the consumer, configured to supply power to the connected load;
- and
- a detection unit configured to detect the amount of electric current flowing from the feeding unit to the load;
- and
- a measurement unit configured to measure the amount of power consumption of each load depending on the amount of electric current detected by the detection unit.
A control device, comprising:
- an analyzing unit configured to convert the time waveform of the amount of electric current flowing from the outlet device to the load to a frequency domain to acquire a frequency pattern;
- a first storage unit configured to store the frequency pattern of each load associated with the load identification information for identifying the load;
- and
- a search unit configured to search the load identification information corresponding to the frequency pattern acquired by the analyzing unit from the first storage unit.
A measuring device that can be connected to an outlet device, comprising:
- a feeding unit, connected to a load within the consumer, configured to supply power to the connected load;
- a detection unit configured to detect the amount of electric current flowing from the feeding unit to the load;
- a measurement unit configured to measure the amount of power consumption of each load depending on the amount of electric current detected by the detection unit;
- and
- an analyzing unit configured to convert the time waveform of the amount of electric current detected by the detection unit to a frequency domain to acquire a frequency pattern.
A power consumption measuring method, comprising:
- a step of supplying power to a load connected to an outlet device provided in a consumer by the outlet device;
- a step of detecting the amount of electric current flowing from the outlet device to the load by the outlet device;
- and
- a step of measuring the amount of power consumption of each load depending on the amount of electric current detected by the step of detecting.
