TEMPERATURE ANOMALY DETECTION SYSTEM, AND TEMPERATURE ANOMALY DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To accurately detect a temperature anomaly generated in an underfloor apparatus installed on the underfloor of a railway vehicle.;SOLUTION: A temperature anomaly detection system acquires an apparatus temperature value which is a temperature value of an underfloor apparatus, and accumulates the acquired apparatus temperature value. The correlation between the underfloor apparatuses is acquired from the apparatus temperature value to be accumulated, and a correlation coefficient is calculated based on an acquired correlation. The correlation coefficient is acquired from the apparatus temperature value to be accumulated with the apparatus temperature value of a determination object apparatus which is the underfloor apparatus desiring for the determination of the temperature anomaly as a determination temperature value. A proper temperature value is predicted from the apparatus temperature value based on the acquired correlation. The proper temperature value is a proper temperature value when the temperature anomaly is not generated in the determination object apparatus. When a deviation which is a value in which the determination temperature value deviates from the proper temperature value is larger than an anomaly determination threshold value as a result of the comparison between the determination temperature value and the proper temperature value, the anomaly determination for determining that the anomaly temperature is generated in the determination object apparatus is performed. An anomaly determination threshold value is the threshold value for determining that the temperature anomaly is generated in the determination object apparatus.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
