<p>PROBLEM TO BE SOLVED: To solve the problem that a special management device is required or the load of power management is concentrated on a specific electric apparatus in order to manage the electric energy consumed by a plurality of electric apparatuses.SOLUTION: Each electric apparatus includes transmission means which, when receiving a data structure having areas to which power consumptions of each electric apparatus and identifiers of each electric apparatus are to be written, writes a current power consumption of the electric apparatus into an area corresponding to the electric apparatus in the data structure and transmits the data structure to another electric apparatus of which the identifier is written in the data structure. Each electric apparatus controls power consumption of the electric apparatus on the basis of the current power consumption of the electric apparatus and power consumption of other electric apparatuses of which the identifiers are written in the data structure. If the transmission means fails to receive ACK from an electric apparatus as a transmission destination, the transmission means transmits the data structure to another electric apparatus other than the transmission destination, of which the identifier is written in the data structure.</p> |
