A method of operating an elevator system includes detecting a building sway which causes sway of elevator suspension or compensation members. An elevator control system is switched into a building sway mode, and operation of one or more elevator cars of the elevator system is changed via the building sway mode to mitigate vibratory effects of the building sway on the one or more elevator cars.

One elevator system includes an elevator car, counterweight, traction sheave, support wrapped around the traction sheave and suspending the car and the counterweight, a compensation sheave, a compensation member wrapped around the compensation sheave and being affixed at a first end to the elevator car and at a second end to the counterweight, and a tensioner. The support is driven by rotation of the traction sheave to raise and lower the car, and the tensioner is in communication with the traction sheave for linearly displacing a rotational centerpoint of the traction sheave. Another elevator system has an elevator car, counterweight, compensation sheave, compensation rope wrapped around the compensation sheave and being affixed to the car and the counterweight, a traction sheave driving a support suspending the car and the counterweight, and a tensioner in communication with the traction sheave for inducing a variation in tension of the compensation rope.

An exemplary building sway operation system (10) for an elevator includes an acceleration sensor (11), and a data receiving unit (12) for receiving a sensor output from the acceleration sensor (11). The acceleration sensor (11) is designed to be mounted on a movable mass (6) of an active vibration control device (5) for a building, in order to detect the reciprocating motion of the movable mass (6) of the active vibration control device (5) responsive to the occurrence of earthquakes or strong winds.

An elevator system constructed in accordance to one embodiment of the present disclosure includes an elevator car, a counterweight, a sheave assembly, a suspension rope, a compensation rope, a first optical sensor assembly and a controller. The suspension rope has a first suspension end coupled to the elevator car and a second suspension end coupled to the counterweight. The first compensation rope has a first compensation end coupled to the elevator car and a second compensation end coupled to the counterweight. The first optical sensor assembly can have a first optical sensor pair including a first emitter and a first receiver. The first emitter is configured to emit a first beam to be received by the first receiver. The first optical sensor pair is configured to detect interruption of the first beam by the first compensation rope. The controller controls movement of the elevator car based on the detected interruption.

A vibration damping device for reducing vibration of an elevator rope includes a displacement amplifier arranged around a region from a first portion of the elevator rope drawn and a second portion of the elevator rope drawn from an opposite side of one or more sheaves in parallel with the first portion. The displacement amplifier is configured to amplify a displacement of each of the first portion and the second portion of the elevator rope. The device also includes a limiting member that controls displacement amplification performed by the displacement amplifier such that the displacement of the first portion or the second portion amplified by the displacement amplifier does not become greater than a first displacement, which is a displacement of the elevator rope by which the elevator rope is not allowed to return to an equilibrium position of the vibration.

A building management system of an occupiable structure with an elevator system includes an elevator video display, a building computing device and a building status system. The building computing device includes a computer processor and a computer readable storage medium. The building status system is configured to send real-time building condition signals to the building computing device, and the building status system is configured to process the real-time building condition signals and output an associated information signal for display on the elevator video display.

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.

A failure detection device for an elevator is provided. The failure detection device includes: a mobile unit that is movable in a hoistway in an up-down direction independently of a car; a distance measurement unit that is mounted to the mobile unit and is configured to measure a horizontal distance; and a control unit including: a movement amount calculator; a car height position acquirer; a reference value storage; a measurement value acquirer; and a determiner. The failure detection device determines whether a failure has occurred in the hoistway based on the measurement value and the reference value stored in the reference value storage in association with the absolute position at which the measurement value has been measured.

According to an aspect, there is provided a solution in which an event requiring a stop to a next possible floor is detected for a moving elevator car. The stop is then selected to the next possible floor, the next possible floor being the closest unlocked floor in the moving direction of the elevator car.

A method of portfolio management for multiple elevator systems. The method being executable for when an incident occurs includes receiving elevator system information from the edge IoT devices of the elevator systems affected by the incident, analyzing the elevator system information to determine how to triage the elevator systems affected by the incident, generating an output in accordance with results of the analyzing, pushing the output to an application layer using application program interfaces (APIs) to provide operators with first status information in real-time, and sending the output to the operators via communication notification protocols to provide the operators with second status information in real-time.
