no. 1 Embodiment approach

[0040]

[0041] figure 1 It is a block diagram showing the configuration of main parts of the abnormal temperature detection device according to the first embodiment of the present invention. Such as figure 1 As shown, the abnormal temperature detection device 1 of the present embodiment has a temperature acquisition unit 11 (temperature acquisition unit), a preprocessing unit 12 (preprocessing unit), a learning unit 13 (learning unit), a judging unit 14 (judging unit), an output The unit 15 and the input unit 16 detect abnormal temperature. Here, the abnormal temperature means a temperature significantly higher than normal, or a temperature significantly lower than normal. In this embodiment, a case where a temperature significantly higher than normal is detected as an abnormal temperature will be described as an example. In addition, the normal temperature and the abnormal temperature are not fixed, and can be changed to any temperature according to the situation in whi...

Abstract

This abnormal temperature detection device is provided with: a temperature acquisition unit that acquires temperature data; and a pre-processing unit that performs a pre-process for calculating differential data indicating a differential sequence of the temperature data, generating replacement data in which either the differential data that is a positive number or the differential data that is a negative number is replaced by zero, and performing a pre-process in which the differential data that is a positive number or the differential data that is a negative number is calculated. Calculating the similarity between the reference data and the replacement data generated according to the teacher data of which the normal or abnormal recognition is completed; a learning unit that performs machine learning on the similarity calculated by the pre-processing unit and outputs a recognition function; and a determination unit that uses the identification function to determine whether the temperature data for detection, which has been acquired by the temperature acquisition unit and has been pre-processed by the pre-processing unit, is normal or abnormal.

Description

technical field [0001] The invention relates to an abnormal temperature detection device, an abnormal temperature detection method and a recording medium. [0002] This application claims the priority of Japanese Patent Application No. 2020-143271 filed on August 27, 2020 and uses the contents thereof here. Background technique [0003] In the event of an accident such as a fire in a residential building, a fire in a coal-fired power station, or a leak of molten steel in a steel factory, loss of human life and opportunity may occur. Therefore, from the viewpoint of avoiding loss of human life and loss of opportunity, it is extremely important to detect abnormal temperature due to occurrence of an accident. In addition, abnormal temperature may be used to mean temperature significantly lower than normal time in addition to the meaning of temperature significantly higher than normal time.
