Document Type and Number:
Japanese Patent JP7127301
Kind Code:
B2
Abstract:
To detect a sensor in which an abnormality has occurred by an information processing apparatus even if the sensor cannot notify the occurrence of the abnormality.SOLUTION: A computer acquires sensor data obtained by a plurality of sensors via a network, and stores the acquired sensor data. Thereafter, the computer generates, for each of a plurality of time ranges, relationship information indicating a relationship between the sensors based on an order in which each of the plurality of sensors detects a detection target. The computer monitors a change in the relationship information generated for each of the plurality of time ranges for each of the plurality of sensors, and detects such a sensor that an abnormality has occurred among the plurality of sensors based on the change in the relationship information.SELECTED DRAWING: Figure 3
