Document Type and Number:
WIPO Patent Application WO/2023/079985
Kind Code:
A1
Abstract:
This sign detection device comprises: a preprocessing unit that acquires a time-series feature amount indicating the operation status of a cooling target device that has a heat source and a cooling unit that cools the heat source with a cooling medium; and a construction unit that generates a training data set on the basis of the time-series feature amount acquired by the preprocessing unit and labels indicating whether the cooling performance of the cooling unit is normal or abnormal, and constructs a sign detection model using the training data set.
