Description

  Embodiments described herein relate generally to an elevator control device.

  Conventionally, in buildings where elevators are installed, inundation sensors are installed in the pits at the bottom of the hoistway. When inundation is detected in the pits due to flooding, etc., control is performed to move the car to the upper floor. ing. By controlling in this way, it is possible to prevent the car from being flooded and to prevent a failure of equipment mounted on the car.

  However, when a major earthquake occurs, the elevator stops immediately and the operation cannot be resumed until the worker performs return work, so even if the tsunami detects inundation in the pit, the car is moved. There was a problem that the car could be flooded due to the inability to drive the car.

  In addition, even if the magnitude of the earthquake is not so large and the operation of the elevator is restored in a short time, if the tsunami occurs, water may invade more rapidly than the flood, and the inside of the building may inundate at a high speed. . In such a case, there has been a problem that there is a possibility that the car will not move in time after the inundation sensor detects the inundation, and the car may be submerged.

  In order to respond to this, it is possible to obtain information on tsunami warnings and tsunami warnings issued by external systems, and use this information to move the car to the upper floor before the tsunami arrives. There is a technology to avoid flooding.
