<p>If a long-period earthquake occurs, it is judged whether any failure is caused or not, and an elevator can be recovered, if any, to its normal operation safely and quickly. An elevator control apparatus comprises a general earthquake sensor and a long-period earthquake sensor which senses the long-period component of the vibration of a building in two levels which the general earthquake sensor does not senses. When the earthquake sensor senses a vibration, an earthquake time control operation is carried out. If the long-period earthquake sensor senses a first level, a long-period earthquake time control operation including report to the outside and inside of the elevator is carried out. If the long-period earthquake sensor senses a second level, a long-period earthquake time control operation is carried out in which a report is sent to the outside and inside of the elevator, the car is moved to the nearest floors and stopped, the door is opened and the closed, the car is moved to a resting floor, and the operation is stopped. Under a predetermined condition, an automatic inspection operation is carried out. If no failure is found out, the operation is returned to the normal operation.</p> |
