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.
