To obtain a platform door condition diagnostic device that accurately diagnoses the condition of platform doors while reducing labor required to calculate the reference value.SOLUTION: A platform door condition diagnostic device comprises: a test platform door reference value construction unit that calculates the frequency distribution of base data acquired by operating a test platform door or a target platform door created by simulating the target platform door to be used for condition diagnosis, and determines a first reference value from the frequency distribution; a target platform door reference value construction unit that calculates the frequency distribution of base data acquired by operating the target platform door after installation on a station platform and determines a second reference value from the frequency distribution; an abnormality determination reference value construction unit that determines an abnormality determination reference value used for condition diagnosis from the first reference value and second reference value; a diagnostic target data calculation unit that calculates the frequency distribution from in-operation status information, which is the status information of the target platform door during operation; and a diagnostic unit that diagnoses the condition of the target platform door using the frequency distribution calculated by the diagnostic target data calculation unit and the abnormality determination reference value.SELECTED DRAWING: Figure 3
