Abstract:
To provide a platform door diagnostic device, a diagnostic method, and a diagnostic program capable of performing diagnosis of soundness more appropriately than the conventional one.SOLUTION: A time series data acquisition unit 321 acquires time series data showing physical quantity relating to control of a platform door or the physical quantity indicating a state of the platform door according to the platform door installed in a platform. A feature value calculation unit 323 calculates a feature value showing a variation feature of the time series data by using the time series data acquired by the time series data acquisition unit 321. A soundness determination unit 324 determines soundness of the platform door by comparing the feature value calculated by the feature value calculation unit 323 with a threshold that is predetermined by using a frequency distribution of a feature value obtained when the platform door is abnormal and a frequency distribution of a feature value obtained when the platform door is normal. An output unit 325 outputs a determination result of the soundness determination unit 324.SELECTED DRAWING: Figure 4
