Abstract
In an elevator system having an elevator control unit and an atmospheric pressure control unit, an elevator operation state monitor monitors the operation state of the elevator control unit, and an atmospheric pressure control state monitor monitors the operation state of the atmospheric pressure control unit. When a trouble in the elevator operation or atmospheric pressure control is detected, a minor/major trouble judgment unit judges the seriousness level of the trouble, and a rescue mode selector selects a rescue mode. In this case, when the atmospheric pressure control is abnormal, it is judged a major trouble, and a mode to ensure ventilation in an elevator car is selected. This enhances the safety in a highly airtight elevator such as a superhigh-speed high-rise elevator.
Claims10
An elevator system having an elevator operation control unit to control the operation of an elevator, and an atmospheric pressure control unit to control the pressure in an elevator car by operating a blower installed in the car, comprising:
- an elevator operation state monitoring means for monitoring the operation state of the elevator operation control unit;
- an atmospheric pressure control state monitoring means for monitoring the operation state of the atmospheric pressure control unit;
- and
- a rescue control means for executing a specific rescue process selected according to the seriousness level of a trouble when a trouble in an elevator is detected by the elevator operation state monitoring means or when an abnormal change in atmospheric pressure is detected by the atmospheric pressure control state monitoring means.
An elevator system having an elevator operation control unit to control the operation of an elevator, and an atmospheric pressure control unit to control the pressure in an elevator car by operating a blower installed in the car, comprising:
- an elevator operation state monitor which monitors the operation state of the elevator operation control unit;
- an atmospheric pressure control state monitor which monitors the operation state of the atmospheric pressure control unit;
- and
- a rescue controller which executes a specific rescue process selected according to the seriousness level of a trouble when a trouble in an elevator is detected by the elevator operation state monitor or when an abnormal change in atmospheric pressure is detected by the atmospheric pressure control state monitor.
