Claims
- 1. A control operation system for an elevator comprising:a flood detector for detecting a flood amount in a hoistway in an elevator; flood speed computing means for computing a flood speed based on the flood amount detected by the flood detector; and flood control operation command means for setting a flood control operation for the elevator based on the flood speed computed by the flood speed computing means, and issuing a command to an elevator.
- 2. The control operation system for an elevator according to claim 1, further comprising flood predicting means for predicting a future flood development based on at least one of the flood amount detected by the flood detector and the flood speed computed by the flood speed computing means, wherein the flood control operation command means sets a flood control operation based on the future flood development predicted by the flood predicting means.
- 3. The control operation system for an elevator according to claim 2, further comprising:display information generating means for editing at least one of the flood amount detected by the flood detector, the flood speed computed by the flood speed computing means, and the future flood development predicted by the flood predicting means into a display format; and a flood display unit for displaying information edited by the display information generating means.
- 4. The control operation system for an elevator according to claim 3, wherein the flood display unit displays an estimated time for flood amount to reach a threshold water level after a flood in the hoistway is detected.
- 5. The control operation system for an elevator according to claim 1, wherein, if a flood in the hoistway reaches a threshold water level at at least a first speed, the flood control operation command means causes the elevator to immediately stop.
- 6. The control operation system for an elevator according to claim 5, wherein, if the flood in the hoistway reaches the threshold water level slower than the first speed but at least as fast as a second speed, the flood control operation command means causes the elevator to stop at the nearest floor.
- 7. The control operation system for an elevator according to claim 6, wherein, if the flood in the hoistway reaches the threshold water level slower than the second speed, the flood control operation command means prevents a new call from being assigned to the elevator, and causes the elevator to stop at a nearest evacuation floor after responding to at least one call that has already been assigned.
- 8. The control operation system for an elevator according to claim 1, wherein if the flood detector detects a flood amount in the hoistway, the flood control operation command means prevents response to a floor proximate a terminal.
- 9. The control operation system for an elevator according to claim 1, further comprising an auxiliary flood detector for detecting at least a water level in a range that should be detected by the flood detector, wherein if the flood detector is not actuated at a water level that should be detected by the flood detector, while the auxiliary detector is actuated, the flood control operation command means causes the elevator to stop at a nearest evacuation floor.
- 10. The control operation system for an elevator according to claim 3, wherein if a flood amount in the hoistway declines without reaching a threshold water level, then the flood predicting means estimates a recovery time required for reaching a water level that permits elevator operation to be resumed, and the flood display unit displays the recovery time estimated.
- 11. The control operation system for an elevator according to claim 10, wherein, when the flood amount in the hoistway reaches the water level that permits elevator the operation to be resumed, the flood control operation command means clears a flood control operation mode and restores a normal operation mode.
- 12. The control operation system for an elevator according to claim 1, wherein once the flood amount in the hoistway has reached a threshold water level, flood control operation is continued even when water level decreases.
- 13. The control operation system for an elevator according to claim 12, further comprising a reset switch, wherein, if the flood control operation continues the reset switch is operated to clear a command for the flood control operation.
