TEMPERATURE ANOMALY DETECTION SYSTEM, AND TEMPERATURE ANOMALY DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To accurately detect occurrence of a temperature anomaly at a monitoring object region of a mobile body composed by one or more vehicles such as a rail travelling vehicle.;SOLUTION: A temperature anomaly detection system is constituted by: a divergence temperature value calculation unit 16 for calculating a divergence temperature value in which a temperature value of a monitoring object region included in a mobile body including detected vehicle composition is a value deviating from a reference value; a specific composition evaluation value extraction unit 17 for extracting a specific composition evaluation value from the calculated divergence temperature value; a whole composition moving average calculation unit 18 for calculating a whole composition moving average which is a moving average of the temperature values in all composition detection mobile bodies based on the calculated divergence temperature values; a moving average standard deviation calculation unit 19 for calculating a moving average standard deviation which is a standard deviation of the moving average based on the whole composition moving average; and a temperature anomaly detection unit 21 for determining that a temperature anomaly occurs at the monitoring object region when the specific composition evaluation value is larger than an anomaly threshold value by comparing the specific composition evaluation value with the anomaly threshold value obtained by multiplying the moving average standard deviation and a preset specified scale factor.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
