Abstract

A smart meter includes: a power supply control unit which causes stoppage of a supply of power passing through the smart meter to an television and so on, when an RD command to stop the supply is received; a first communication unit which performs a first communication through which the RD command is received; a second communication unit which performs a second communication; and a communication control unit which: causes the performance of the first communication before the RD command is received; and prohibit the performance of the first communication and cause only the performance of the second communication, after the RD command is received.

First claim

The invention claimed is:

1. A smart meter comprising:
a power supply control unit configured to control stoppage of a supply of power through the smart meter to an electrical device when a command to stop the supply is received;
a first communication unit configured to perform a first communication and to receive the command;
a second communication unit configured to perform a second communication; and
a communication control unit configured to:
control the performance of the first communication until the command is received by the first communication unit; and
prohibit the performance of the first communication and control the performance of only the second communication, after the command is received by the first communication unit,
wherein the power supply control unit is configured to prohibit the supply of power from a power grid to an electrical device and control power from a predetermined storage battery to be supplied to the electrical device, after the command is received by the first communication unit,
the smart meter:
operates in one of a plurality of modes including a first mode and a second mode; and
operates in the first mode when the command is not received, and operates in the second mode upon receiving the command, and
the communication control unit is configured to:
control the performance of the first communication during operation in the first mode; and
prohibit the performance of the first communication and control the performance of only the second communication, during operation in the second mode, and
wherein during operation in the second mode, the power supply control unit is configured to control stoppage of only the supply of the power from the power grid to the electrical device, out of the smart meter and the electrical device, and
the smart meter operates under the power from the power grid even during operation in the second mode.

2. The smart meter according to claim 1 ,
wherein the first communication unit is configured to perform communication through a first communication network, and
the second communication unit is configured to perform communication through a second communication network different from the first communication network.

3. The smart meter according to claim 2 ,
wherein the second communication network is a mobile phone network.

4. The smart meter according to claim 1 ,
wherein the smart meter:
operates in a third mode when not operating in the second mode, when the command is received; and
operates under power from a predetermined storage battery and not under the power from the power grid, during operation in the third mode, and
the communication control unit is configured to control the performance of the first communication during operation in the third mode.

5. The smart meter according to claim 1 ,
wherein, when the command is received, the smart meter operates in a fourth mode after operating in the second mode,
the second communication is communication which passes through the electrical device, and
the power supply control unit is configured to:
control power from a predetermined storage battery to be supplied to the electrical device during operation in the second mode; and
control the power from the power grid to be supplied to the electrical device during operation in the fourth mode.

6. The smart meter according to claim 1 , comprising
a record transmitting unit configured to transmit, using the second communication, a record of an operation of the smart meter to the electrical device after the command is received, the operation being an operation of the smart meter before the command is received.

7. The smart meter according to claim 6 ,
wherein the second communication unit is configured to receive, from the electrical device to which the record is transmitted, data specifying an operation of the smart meter, and
the smart meter performs the operation specified by the data, when the data is received.

8. The smart meter according to claim 1 ,
wherein the smart meter operates at a first frequency before the command is received, and operates at a second frequency lower than the first frequency after the command is received.

9. The smart meter according to claim 1 ,
wherein the smart meter operates on first firmware before the command is received, and operates on second firmware after the command is received.

10. The smart meter according to claim 1 ,
wherein the smart meter operates under a first CPU before the command is received, and operates under a second CPU after the command is received.

11. A system comprising:
the smart meter according to claim 1 ;
an electrical device; and
a server,
wherein the smart meter:
receives the command from the server, using the first communication; and
includes a record transmitting unit configured to transmit, using the second communication, a record of an operation of the smart meter to the electrical device, when the command is received,
the electrical device transmits the transmitted record to the server,
the server transmits, to the electrical device, first data and second data which are generated from the transmitted record, the first data specifying an operation of the smart meter, and the second data specifying an operation of the electrical device, and
the electrical device performs the operation specified by the transmitted second data, and transmits the transmitted first data to the smart meter, and
the smart meter performs the operation specified by the transmitted first data.

12. A supply control method comprising:
controlling a supply of power through a smart meter to an electrical device to be stopped, when a command to stop the supply is received by a first communication unit that performs a first communication, the first communication unit and a second communication unit being included in the smart meter;
controlling the performance of the first communication until the command is received by the first communication unit; and
prohibiting the performance of the first communication and controlling performance of only a second communication by the second communication unit, after the command is received by the first communication unit,
wherein the supplying of power prohibits the supply of power from a power grid to an electrical device and controls power from a predetermined storage battery to be supplied to the electrical device, after the command is received by the first communication unit,
the smart meter operates in one of a plurality of modes including a first mode and a second mode, and operates in the first mode when the command is not received and operates in the second mode upon receiving the command,
performance of the first communication is controlled during operation in the first mode, and the performance of the first communication is prohibited and performance of only second communication is controlled during operation in the second mode, and
wherein during operation in the second mode, stoppage of only the supply of the power from the power grid to the electrical device is controlled, out of the smart meter and the electrical device, and
the smart meter operates under the power from the power grid even during operation in the second mode.

13. An operating method executed in a system including the smart meter according to claim 1 , an electrical device, and a server, the method comprising:
transmitting a record of an operation of the smart meter to the electrical device, when the command is received from the server through the first communication, the transmitting being performed by the smart meter using the second communication;
transmitting th
