BACKGROUND

1. Technical Field

The present disclosure relates to an information processing device and an anomaly visualizing system.

2. Description of the Related Art

There is known the use of a smart meter for detecting occurrence of a power failure in a power distribution system (for example, refer to Japanese Patent Application Laid-open Publication No. 2015-233278 (JP-A-2015-233278)).

In a case in which a function of a smart meter is impaired, a power failure may occur due to stop of electric supply in a system in which a power usage amount is measured by the smart meter. However, with the method disclosed in JP-A-2015-233278, it has been difficult to determine whether the power failure is caused by impairment of the function of the smart meter.

For the foregoing reasons, there is a need for an information processing device and an anomaly visualizing system that can determine a power failure that is caused due to impairment of a function of a smart meter.

SUMMARY

According to an aspect, an information processing device includes: a receiver configured to receive information related to a plurality of smart meters; a controller configured to determine presence or absence of an anomaly in each of the smart meters based on a reception status of the information from each of the smart meters; and an output unit configured to output information indicating presence or absence of an anomaly in each of the smart meters. The receiver receives the information from the smart meters in a cycle of a first predetermined time. The controller determines that an anomaly is occurring in a smart meter from which information has not been obtained for a second predetermined time that is longer than the first predetermined time. The second predetermined time is n times as long as the first predetermined time, and n is equal to or greater than 2.

According to another aspect, an anomaly visualizing system includes: a plurality of smart meters configured to transmit information indicating a power usage amount in a cycle of a first predetermined time; an integration device configured to relay information transmitted from one or more of the smart meters; a relay device configured to store information indicating presence or absence of an anomaly in the integration device; an extraction device configured to extract, based on information from the smart meters, the integration device, or both, a smart meter from which information has not been obtained for a second predetermined time or more, the second predetermined time being longer than the cycle of the first predetermined time; a power distribution information providing device configured to store information indicating presence or absence of an anomaly in a power distribution system connected to a facility the power usage amount of which is detected by the smart meters; an anomaly visualizing device that is provided to be able to communicate with the extraction device and the power distribution information providing device and is configured to output, based on information from the extraction device and the power distribution information providing device, a map image indicating a location of the smart meter in which an anomaly is occurring; a controller configured to determine presence or absence of an anomaly in each of the smart meters based on a reception status of information from each of the smart meters; and an output unit configured to output information indicating presence or absence of an anomaly in each of the smart meters. The anomaly visualizing device includes storage configured to store information indicating locations of the smart meters, and information indicating a correspondence relation between each of the smart meters and the power distribution system, and a controller configured to determine that an anomaly is occurring in a smart meter in a case in which information has not been obtained for the second predetermined time or more from the smart meter configured to detect the power usage amount of the facility connected to the power distribution system having no anomaly. The second predetermined time is n times as long as the first predetermined time, n is equal to or greater than 2, and the controller determines that an anomaly is occurring in a smart meter in a case in which information has not been obtained from the smart meter for the second predetermined time or more and an integration device having no anomaly is interposed in a transmission and reception path for the information related to the smart meter.
