PROBLEM TO BE SOLVED: To provide a diagnostic system and an elevator that update learning data such that an effect of outlier values is suppressed by using sensor data diagnosed to be normal, and that are capable of tracking secular deterioration.SOLUTION: Provided is a diagnostic system 100, or an elevator provided with the diagnostic system 100, that diagnoses a state of a diagnosis object device on the basis of sensor data S10 which is data from a sensor installed in the diagnosis object device and diagnostic learning data S30. The diagnostic system 100, or the elevator provided with the diagnostic system 100, includes: a diagnostic unit 10 which diagnoses a state of the diagnosis object device on the basis of the sensor data and the diagnostic learning data; and a learning data update unit 20 which adds the sensor data when diagnosed to be normal by the diagnostic unit to an accumulated learning data group retained in beforehand, updates the accumulated learning data group such that only a core of the accumulated learning data group and data which is close to the core data remain and so that distant data is eliminated from the accumulated learning data group, and generates new diagnostic learning data from the updated accumulated learning data group. |
