PROBLEM TO BE SOLVED: To provide a failure diagnosis device, system and method capable of accurately diagnosing a failure in an elevator device.SOLUTION: A failure diagnosis device of an exemplary embodiment comprises a specification acquiring part, an ideal timing acquiring part, a failure diagnosis part and a notification part. The specification acquiring part acquires specifications of an elevator device to be a target for failure diagnosis. The ideal timing acquiring part acquires ideal timing meeting with predetermined requirements in a case where the elevator device is normal on the basis of status of the elevator device, action command and start time of the action specified by the action command. The failure diagnosis part diagnoses a failure in the elevator device on the basis of time-lag between the ideal timing and actual timing in which the elevator device actually meets the predetermined requirement. The notification part notifies diagnosis result.SELECTED DRAWING: Figure 1 |
