Patent attributes
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).
