The invention provides an emergency operation device for an elevator, and a method thereof. The emergency operation device for the elevator controls the elevator to perform emergency operation if vibration of a building is detected. The emergency operation device comprises: a vibrometer for detecting the vibration of the building; a shaking amount calculating unit for calculating in real-time, for each floor of the building, the natural period of the building and the shaking amount of an elongated object in an elevator hoistway in a period near the natural period based on a detection signal upon the detection of vibration by the vibrometer; and an operation control unit which, if the shaking amount of any period of each floor calculated by the shaking amount calculating unit reaches a specified threshold stored in a storage unit, determines the floor with the shaking amount to be a resonance floor, or if the shaking amount is predicted to reach a threshold, determines the floor that is predicted to have the shaking amount to be a possible resonance floor, and controls the elevator to perform emergency operation such that the elevator does not stop at the resonance floors and the possible resonance floors. |
