Abstract
The power information management device is directly or indirectly connected to a communication network and is provided with: wiring that transmits power; a power measurement unit that measures an amount and a direction of the power transmitted through the wiring; a power information generation unit that generates, on a predetermined period basis, power information that represents the amount and the direction of the power measured by the power measurement unit; and a communication unit that transmits the power information to the communication network, wherein a load unit, a power generation unit and a power storage unit are directly or indirectly connectable to the wiring.
Claims12
A power information management device directly or indirectly connected to a communication network, the power information management device being used for a power information management system including a settlement computer that is connected to the communication network and a plurality of power information management devices directly or indirectly connected to the communication network,
- wherein identification information, which is unique to one of registered users for the power information management system, is given to the power information management device, and settlement is performed for the one of registered users,
- wherein the power information management device comprises:
- wiring that transmits power, a load unit, a power generation unit and a power storage unit being directly or indirectly connectable to the wiring;
- a power measurement unit that measures an amount and a direction of the power transmitted through the wiring;
- a power information generation unit that generates, on a predetermined period basis, power information that represents the amount and the direction of the power measured by the power measurement unit;
- a communication unit that transmits, to the communication network, the power information having attached therewith the identification information given to the power information management device, and receives second power information transmitted from a device different from the power information management device;
- and
- an identification information determination unit that determines whether or not identification information attached to the second power information received by the communication unit matches the identification information given to the power information management device,
- wherein:
- if it is determined that the identification information attached to the second power information fails to match the identification information given to the power information management device, the power information generation unit modifies the power information based on the second power information, and the communication unit transmits the modified power information and the second power information to the settlement computer through the communication network;
- and
- if it is determined that the identification information attached to the second power information matches the identification information given to the power information management device, the communication unit transmits the power information without modification to the settlement computer through the communication network and does not transmit the second power information.
A power information management system, comprising:
- a settlement computer that is connected to a communication network;
- and
- a plurality of power information management devices, each being given identification information, wherein
- each of the plurality of power information management devices comprises:
- wiring that transmits power, a load unit, a power generation unit and a power storage unit being directly or indirectly connectable to the wiring;
- a power measurement unit that measures an amount and a direction of the power transmitted through the wiring;
- a power information generation unit that generates, on a predetermined period basis, power information that represents the amount and the direction of the power measured by the power measurement unit;
- a communication unit that transmits, to the communication network, the power information having attached therewith the identification information given to the power information management device, and receives second power information transmitted from a device different from the power information management device;
- and
- an identification information determination unit that determines whether or not identification information attached to the second power information received by the communication unit matches the identification information given to the power information management device,
- wherein:
- if it is determined that the identification information attached to the second power information fails to match the identification information given to the power information management device, the power information generation unit modifies the power information based on the second power information, and the communication unit transmits the modified power information and the second power information to the settlement computer through the communication network;
- and
- if it is determined that the identification information attached to the second power information matches the identification information given to the power information management device, the communication unit transmits the power information without modification to the settlement computer through the communication network and does not transmit the second power information, and
- wherein the identification information is unique to each of registered users for the power information management system, and settlement is performed based on each of the registered users.
