摘要:
An object of the present invention is to provide a sway amount estimation system that can suppress a reduction in user convenience that would occur if the operation method is switched more than necessary. A sway amount estimation system (300) includes a sensing unit (78), a judgment unit (80), and an estimation unit (79). The estimation unit (79) calculates an estimated value of the amount of sway of an elevator rope due to vibration caused by building sway based on the sway sensed by the sensing unit (78) and an estimation model incorporating the effect of the displacement amplification of the displacement amplifier (7). The judgment unit (80) judges if the estimated value calculated by the estimation unit (79) is greater than a threshold for switching the operation method for the elevator apparatus (11).

An object of the invention is to provide a vibration damping system that can avoid the occurrence of resonance of an elevator rope regardless of the vibration frequency of a vibration source. A vibration damping system (200) includes a displacement amplifier (7), a calculation unit (66), and a displacement amplification control unit (67). The displacement amplifier (7) is arranged along a given position in the longitudinal direction of the elevator rope. The displacement amplifier (7) amplifies a displacement due to vibration of the elevator rope based on a variable amplification factor. The calculation unit (66) calculates the natural frequency of the elevator rope. The displacement amplification control unit (67) controls the displacement amplification of the displacement amplifier (7) based on the natural frequency calculated by the calculation unit (66) and a preset vibration frequency.

Embodiments are directed to detecting motion of a building housing a multi-deck elevator system, determining, by a processing device, that the detected motion of the building is greater than a threshold, and controlling access to at least one deck of the elevator system based on determining that the detected motion of the building is greater than the threshold such that the at least one deck still is enabled to traverse a hoist-way of the elevator system.

An elevator control device includes a control device body controlling operation of one or more elevators operated between plural floors of a building, and carries out emergency evacuation operation for evacuating people by using an elevator when the building suffers from fire, earthquake, or the like. The elevator control device includes a damage detector that detects damage due to disaster at each floor and outputs the detected damage as damage information of each floor; and a person detector that detects the number and positions of persons present at each floor and outputs these data as person number and position information, and in the emergency evacuation operation, the elevator control device body develops an elevator evacuation operation plan based on the position of the elevator car, the damage information, and the person number and position information, and controls the operation of elevator based on the developed evacuation operation plan.

An elevator controller which enables a stop to be made at the nearest floor in the event of a disaster and can prevent users from being shut up in an emergency landing entrance floor. The elevator controller includes an operation mode controller, a door open/close controller which causes the elevator to open the elevator door at the nearest emergency landing entrance floor for a given time when the operation mode controller has returned an operation mode from an emergency operation mode to a normal operation mode, and an informing controller which causes an informing device, which is provided in a hall of an emergency landing entrance floor for which the door open/close controller causes the door to be opened for a given time or provided in the car, to provide information to the effect that the elevator can be used when the operation mode-controller has returned the operation mode from the emergency operation mode to the normal operation mode.
摘要:
A method for controlling an elevator installed in a building that includes an elevator car arranged to travel in a hoistway between floor landings that are at different heights, one or more ropings connected to the elevator car, a hoisting machine for moving the elevator car, and a control for control the hoisting machine is provided. In the method, the sway data of the building is determined, which data describes the strength of the sway of the building, and the starting position data of the elevator car is determined, which starting position data contains data about the starting position of the elevator car and/or data about how long the elevator car has been in the starting position, and the settings for the run speed of the next run are determined on the basis of the starting position data and the sway data. An elevator is configured to perform the method.

When a long-period-earthquake occurs, an elevator is controlled to ensure that an abnormality is positively judged and that the elevator can be safely and promptly returned to a normal operation. For this purpose, by providing a usual seismic sensor and a long-period seismic sensor that detects long-period components of the shakes of a building, which are not detected by the usual seismic sensor, at two stages, an earthquake emergency return operation is performed when the seismic sensor has gone into action and when a first level has been detected by the long-period seismic sensor, a long-period-earthquake emergency return operation, which involves giving a notice to outside the elevator and inside a car, is performed. When a second level has been detected by the long-period seismic sensor, a notice is given to outside the elevator and inside a car, and a door opening action is performed by stopping the car at the nearest floor and a long-period-earthquake emergency return operation, which involves causing the car to travel to a temporary-stop floor, is performed, whereby the car is caused to suspend the operation. When no abnormality is discovered by performing an automatic inspection operation under prescribed conditions, the elevator is returned to a normal operation.
