Power collecting device, power measuring device, and power collecting method

Abstract

A power collecting device () according to the present invention includes: a polling interval determination unit configured to determine a polling interval () as a time interval at which measured data () is collected from an appliance (); a band measurement unit configured to measure a communicable band () usable for communication between the 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 () becomes equal to or smaller than a data volume that can be communicated at 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 data transmission request message () requesting the appliance () for transmitting the measured data () including the measured value obtained through the measurement at the sampling interval ().
