Sensor drift diagnostic device, sensor drift diagnostic method and sensor drift diagnostic program

摘要

PROBLEM TO BE SOLVED: To provide a sensor drift diagnostic device, a sensor drift diagnostic method and a sensor drift diagnostic program capable of more accurately diagnosing drift of a sensor for measuring temperature or humidity in a space. A sensor drift diagnostic device of an embodiment has an absolute temperature calculation unit, a reference data generation unit, a drift score calculation unit, and a drift diagnosis unit. The absolute temperature calculation unit calculates the measured value of the absolute humidity of the target space based on the measured values of the temperature and the relative humidity of the target space. The reference data generation unit is data used for diagnosing the drift of a sensor that measures the temperature and relative humidity of the space, and generates reference data for giving a comparison target to the measured value of the sensor. .. The drift score calculation unit calculates an index value related to the drift based on the reference data. The drift diagnosis unit diagnoses the drift of the sensor based on the index value.
