POWER COLLECTION DEVICE, POWER MEASUREMENT DEVICE, AND POWER COLLECTION METHOD
First Claim
1. A power collecting device being connected to a network and collecting, from an appliance connected to the network, measured data including one or a plurality of pieces of at least one kind of data of current power consumption and accumulated power consumption of the appliance, said power collecting device comprising:
- a polling interval determination unit configured to determine a polling interval as a time interval at which the measured data is collected from the appliance;
a band measurement unit configured to measure a communicable band usable for communication between said power collecting device and the appliance;
a sampling interval determination unit configured to determine a sampling interval as an interval between measurement times of a plurality of measured values included in the measured data so that a data volume of the measured data defined by the sampling interval and the polling interval becomes equal to or smaller than a data volume that can be communicated within the polling interval by using the communicable band; and
a data transmission request unit configured to transmit, to the appliance at the polling interval, a request message requesting the appliance for transmitting the measured data including the measured value obtained through the measurement at the sampling interval.

Abstract
A power collecting device (101) according to the present invention includes: a polling interval determination unit configured to determine a polling interval (212) as a time interval at which measured data (220) is collected from an appliance (102); a band measurement unit configured to measure a communicable band (711) usable for communication between the power collecting device (101) and the appliance (102); a sampling interval determination unit (710) configured to determine a sampling interval (712) as an interval between measurement times of a plurality of measured values included in the measured data (220) so that a data volume of the measured data (220) becomes equal to or smaller than a data volume that can be communicated at the polling interval (212) by using the communicable band (711); and a data transmission request unit (204) configured to transmit, to the appliance (102) at the polling interval (212), a data transmission request message (213) requesting the appliance (102) for transmitting the measured data (220) including the measured value obtained through the measurement at the sampling interval (712).

9. A power collecting device being connected to a network and collecting, from an appliance connected to the network, measured data including a plurality of measured values indicating current power consumption of the appliance for each time measured by the appliance, said power collecting device comprising:
-
a target appliance management unit configured to hold the number of connections as the number of the appliances connected to the network; a timer interval determination unit configured to determine, based on the number of connections, communication speed of the network, and network protocol specifications, a timer interval as a time interval at which the appliance transmits the measured data to said power collecting device; and a data transmission request unit configured to transmit to the appliance a request message requesting the appliance for transmitting the measured data at the timer interval.
