Patent US9130411


Issued 2015-09-08

Smart Meter, Supply Control Method, Operating Method, Integrated Circuit, System, And Program

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.

4 Independent Claims

  • 1. A smart meter comprising: a power supply control unit configured to control stoppage of a supply of power passing 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 first communication unit is configured to perform communication that does not pass through a predetermined device, the second communication unit is configured to perform communication which passes through the predetermined device, the predetermined device is the electrical device to which the power from a power grid is supplied, and the power supply control unit is configured to prohibit the supply of the power from the power grid to the predetermined device and control power from a predetermined storage battery to be supplied to the predetermined device, after the command is received by the first communication unit.

  • 15. A supply control method comprising: controlling a supply of power passing 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 first communication performs communication that does not pass through a predetermined device, the second communication performs communication that passes through the predetermined device, the predetermined device is the electrical device to which the power from a power grid is supplied, and the supplying of power prohibits the supply of the power from the power grid to the predetermined device and controls power from a predetermined storage battery to be supplied to the predetermined device, after the command is received by the first communication unit.

  • 16. An integrated circuit comprising: a power supply control unit configured to control a supply of power passing 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; 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 performance of only a second communication by the second communication unit, after the command is received by the first communication unit, wherein the first communication unit is configured to perform communication that does not pass through a predetermined device, the second communication unit is configured to perform communication which passes through the predetermined device, the predetermined device is the electrical device to which the power from a power grid is supplied, and the power supply control unit is configured to prohibit the supply of the power from the power grid to the predetermined device and control power from a predetermined storage battery to be supplied to the predetermined device, after the command is received by the first communication unit.

  • 17. A non-transitory computer-readable recording medium for use in a computer, the non-transitory computer-readable recording medium having a computer program recorded thereon for causing the computer to execute steps comprising: controlling a supply of power passing 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 causing performance of only a second communication by the second communication unit, after the command is received by the first communication unit, wherein the first communication performs communication that does not pass through a predetermined device, the second communication performs communication that passes through the predetermined device, the predetermined device is the electrical device to which the power from a power grid is supplied, and the supplying of power prohibits the supply of the power from the power grid to the predetermined device and controls power from a predetermined storage battery to be supplied to the predetermined device, after the command is received by the first communication unit.
