Patent ID: 7926620

Claim:
An elevator control apparatus performing control operations in response to shakes of a building provided with an elevator, characterized in that the elevator control apparatus comprises: a seismic sensor that is provided in the building and detects the shakes of the building at a plurality of levels, a long-period seismic sensor that is provided in the building and detects long-period components of the shakes of the building not detected by the seismic sensor at a prescribed first level and a second level higher than the first level, operation control means that performs an earthquake emergency return operation when the shakes of the building have been detected by the seismic sensor, long-period-earthquake first-level control operation means that gives a notice to outside the elevator and inside a car when a first-level long-period component has been detected by the long-period seismic sensor, long-period-earthquake second-level control operation means that gives a notice to outside the elevator and inside the car when a second-level long-period component has been detected by the long-period seismic sensor, performs a door opening action by stopping the car at the nearest floor, and causes the car to travel to a temporary-stop floor after a lapse of a prescribed time, thereby causing the car to suspend the operation, and operation mode restoration means which causes a normal operation to be restored when, in a case where a second-level long-period component is not detected within a prescribed time after the detection of a first-level long-period component by the long-period seismic sensor, a prescribed time has elapsed after the first-level long-period component is not detected any more, and which causes an normal operation to be restored when, in a case where a second-level long-period component is detected within a prescribed time after the detection of a first-level long-period component by the long-period seismic sensor, no abnormality is discovered in an automatic inspection operation performed thereafter.
