<p>An embodiment of the present invention relates to a control device of an elevator having an electronic earthquake sensor. In the case of having the electronic earthquake sensor, the control device also can suitably deal with the earthquake occurring during the period of power failure. The control device (5) of the elevator has: a driving judging part (20a) for judging whether a PS wave sensor (101) is in a driving state through electric power of a storage battery (103) during the period of power failure when the electronic PS wave sensor (101) recovers from a power failure state in the case of not detecting the earthquake; an operation command outputting part (24) for outputting a diagnosis operation command in the case that the PS wave sensor (101) is judged to be not in the driving state during the period of power failure; and an operation control part (25) for performing diagnosis operation through the diagnosis operation command to determine whether there is an abnormality, so as to start normal operation again in the case of no abnormality and to stop operation in the case of the abnormality.</p> |
