Abnormal temperature detection device, abnormal temperature detection method, and abnormal temperature detection program

摘要

PROBLEM TO BE SOLVED: To provide an abnormal temperature detecting device, an abnormal temperature detecting method, and an abnormal temperature detecting program capable of detecting an abnormal temperature with high accuracy while eliminating the influence of an ambient environment and considering the time change of the temperature. An abnormal temperature detection device calculates a temperature acquisition unit that acquires temperature data and difference data indicating a difference number sequence of temperature data, and either the difference data that is a positive number or the difference data that is a negative number. The pre-processing unit and the pre-processing unit generate replacement data in which one is replaced with zero, and perform pre-processing to calculate the similarity between the reference data and the replacement data generated from the teacher data for which normality or abnormality has been identified. A learning unit that machine-learns the calculated similarity and outputs an identification function, and a discrimination function that determines whether the temperature data for detection is normal or abnormal, which is acquired by the temperature acquisition unit and preprocessed by the preprocessing unit. It is provided with a determination unit for determining by using. [Selection diagram] Fig. 1
