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, configured to:

detect a first identification information in a power packet during power distribution;

detect a second identification information in the power packet, wherein the second identification information is next to the first identification information in the power packet;

determine an interval between the detection of the first identification information and the detection of the second identification information, wherein the determined interval corresponds to a first interval of a partitioned power detected during the power distribution, wherein the partitioned power is interposed between the detected first identification information and the detected second identification information;

detect a second interval specified by the partitioned power interposed between the detected first identification information and the detected second identification information; and

determine that a distribution abnormality has occurred in the power distribution in an event the determined first interval of the partitioned power detected during the power distribution is different from the second interval specified by the partitioned power.

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

wherein the second 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 the power packet is configured such that the first identification information and the second identification information are integrated with the partitioned power,

wherein the first identification information and the second identification information correspond to header portions of the power packet, and

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

5. The distribution abnormality detecting device according to claim 4, wherein the second interval specified by the partitioned power is a power packet length.

6. The distribution abnormality detecting device according to claim 1, wherein, in an event 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, in an event 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 first identification information and the second identification information.

8. The distribution abnormality detecting device according to claim 7, wherein the power receiving facility or device information included in the first identification information and the second identification information includes information of the 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, in an event 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 the power receiving facility or device for which suspension of power supply is to be inhibited.

11. A power transmission and reception control device, comprising:

a distribution abnormality detecting device configured to;

detect a first identification information in a power packet during power distribution;

detect a second identification information in the power packet, wherein the second identification information is next to the first identification information in the power packet;

determine an interval between the detection of the first identification information and the detection of the second identification information, wherein the determined interval corresponds to a first interval of a partitioned power detected during the power distribution, wherein the partitioned power is interposed between the detected first identification information and the detected second identification information; and

detect a second interval specified by the partitioned power interposed between the detected first identification information and the detected second identification information,

wherein transmission and reception of power are controlled in an event the determined first interval of the partitioned power detected during the power distribution is different from the second interval specified by the partitioned power.

12. A power supply control device, comprising:

a distribution abnormality detecting device configured to;

detect a first identification information in a power packet during power distribution;

detect a second identification information in the power packet, wherein the second identification information is next to the first identification information in the power packet;

determine an interval between the detection of the first identification information and the detection of the second identification information, wherein the determined interval corresponds to a first interval of a partitioned power detected during the power distribution, wherein the partitioned power is interposed between the detected first identification information and the detected second identification information; and

detect a second interval specified by the partitioned power interposed between the detected first identification information and the detected second identification information,

wherein supply of power is controlled in an event the determined first interval of the partitioned power detected during the power distribution is different from the second interval specified by the partitioned power.
