Abstract

There is provided a distribution abnormality detecting device that detects a distribution abnormality of partitioned power with identification information, the distribution abnormality detecting device being configured to: determine that the distribution abnormality has occurred when an interval of the identification information detected during power distribution is different from an interval specified by the partitioned power.

Claims

1. A distribution abnormality detecting device that detects a distribution abnormality of partitioned power with identification information, the distribution abnormality detecting device being configured to:

determine that the distribution abnormality has occurred when an interval of the identification information detected during power distribution is different from an interval specified by the partitioned power.

2. The distribution abnormality detecting device according to claim 1,

wherein the interval specified by the partitioned power is a constant time interval.

3. The distribution abnormality detecting device according to claim 1,

wherein the partitioned power is constant.

4. The distribution abnormality detecting device according to claim 1,

wherein a power packet is configured such that the identification information is integrated with the partitioned power,

the identification information corresponds to a header portion of the power packet, and

the partitioned power corresponds to a payload portion of the power packet.

5. The distribution abnormality detecting device according to claim 4,

wherein the interval specified by the partitioned power is a power packet length.

6. The distribution abnormality detecting device according to claim 1,

wherein, when it is determined that the distribution abnormality has occurred, distribution or reception of power is suspended.

7. The distribution abnormality detecting device according to claim 1,

wherein, when it is determined that the distribution abnormality has occurred, supply of power to a power receiving facility or device is suspended based on power receiving facility or device information included in the identification information.

8. The distribution abnormality detecting device according to claim 7,

wherein the power receiving facility or device information included in the identification information includes information of a power receiving facility or device for which suspension of power supply is to be inhibited.

9. The distribution abnormality detecting device according to claim 1, further comprising:

a storage device,

wherein, when it is determined that the distribution abnormality has occurred, supply of power to a power receiving facility or device is suspended based on power receiving facility or device information stored in the storage device.

10. The distribution abnormality detecting device according to claim 9,

wherein the power receiving facility or device information includes information of a power receiving facility or device for which suspension of power supply is to be inhibited.

11. A power transmission and reception control device that transmits and receives partitioned power with identification information, comprising:

a distribution abnormality detecting device that detects identification information during power distribution,

wherein transmission and reception of power are controlled when an interval of the identification information detected by the distribution abnormality detecting device is different from an interval specified by the partitioned power.

12. A power supply control device that supplies partitioned power with identification information, comprising:

a distribution abnormality detecting device that detects identification information during power distribution,

wherein supply of power is controlled when an interval of the identification information detected by the distribution abnormality detecting device is different from an interval specified by the partitioned power.

13. A packet structure transmission control device that controls transmission of a packet structure that contains (A) a payload specified by a physical amount and (B) header information including a payload length of the payload, wherein the packet structure transmission control device determines that an abnormality has occurred in transmission of the packet structure when data that is based on the payload length of the payload obtained by the packet structure transmission control device does not match data related to the payload length in the header information obtained by the packet structure transmission control device.

14. The packet structure transmission control device according to claim 13,

wherein transmission of the packet structure is controlled when it is determined that an abnormality has occurred in transmission of the packet structure.
