Title:
COMMUNICATION SYSTEM AND COMMUNICATION METHOD
Document Type and Number:
Japanese Patent JP2019061411
Kind Code:
A
Abstract:
To efficiently acquire integral power consumption even without increasing memory capacity of a measurement device.SOLUTION: A communication system 1 comprises a measurement device 10 and an HGW 20. The measurement device 10 includes an acquisition unit and a transmission unit. The acquisition unit acquires power consumption that is measured on a predetermined time zone basis, in a time zone and time information indicating the time zone in which the power consumption is measured. In a case where a transmission request of history data of the power consumption is received, the history data of the power consumption corresponding to the transmission request are read out of a first storage unit and transmitted to a request source by the transmission unit. The HGW 20 includes a storage unit, a request unit and an integral power consumption calculation unit. The storage unit stores the latest integral power consumption as reference data. The request unit requests transmission of history data of power consumption to the measurement device 10. Based on the history data of the power consumption acquired from the measurement device 10 and the reference data, the integral power consumption calculation unit calculates integral power consumption at a time subjected to calculation.SELECTED DRAWING: Figure 1
