POWER COLLECTION DEVICE, POWER MEASUREMENT DEVICE, AND POWER COLLECTION METHOD

摘要

Disclosed is a power collection device (101) equipped with a polling interval determination unit (203) that determines a polling interval (212), which is the interval of time in which measurement data (220) is collected from a device (102); a bandwidth measurement unit (709) that measures the bandwidth available for communication (711), which can be used for communication between the power collection device (101) and the device (102); a sampling interval determination unit (710) that determines a sampling interval (712), which is the measurement time interval of a plurality of measurement values included in the measurement data (220), in a manner such that the data volume of the measurement data (220) is no more than the data volume that can be communicated within the polling interval (212) using the bandwidth available for communication (711); and a data transmission request unit (204) that transmits a data transmission request message (213), which requests the device (102) to transmit the measurement data (220) that includes the measurement values measured during the sampling interval (712), to the device (102) during the polling interval (212).
