Abstract: An elevator system includes a first elevator car (28) constructed and arranged to move in a first lane (30, 32, 34) and a first propulsion system (40) constructed and arranged to propel the first elevator. An electronic processor of the elevator system is configured to selectively control power delivered to the first propulsion system (40). The electronic processor includes a software-based power estimator configured to receive a first weight signal and a nm trajectory signal for calculating a power estimate and comparing the power estimate to a maximum power allowance. The electronic processor is configured to output an automated command signal if the power estimate exceeds the maximum power allowance.

Abstract: A system for controlling and configuration of an occupant evacuation operation (OEO) in a multi-story building has an elevator control system, a fire alarm detection system with a plurality of fire sensor devices, wherein the fire alarm detection system generates fire alarm information signals, and a central control system coupled with the elevator control system and the fire alarm detection system. The central control system has a data processing system with a processor and memory which provide a configurable model of the multi-story building, receive signals from the fire alarm detection system and receive signals and transmit control signals from/to the elevator control system. The configurable model allows configuration of the system creating a model of the functionalities in the multi-story building required for the OEO, and the central control system controls the OEO based on the signals received from the fire alarm detection system and the elevator control system.

Abstract: A method and system for reducing rollback in a counterbalancing system as a holding brake is released is disclosed. A limited amount of movement of a drive shaft is present in the holding brake. A motor drive provides current to the motor with the holding brake set such that a torque is applied at the drive shaft. The current is controlled to generate torque in both directions. The limited amount of movement in the brake may be used to determine a direction and magnitude of torque required to support a mechanical load being applied to the motor. The motor drive then provides a current to generate the necessary torque required to support the load prior to releasing the holding brake.

Abstract: The present invention relates to a method for controlling an operation of an elevator, which is capable of moving the elevator to a near floor by using an auxiliary power supply such as a battery in an emergency situation where a commercial power supply cannot be used, while minimizing power consumption through automatic control. The method includes: detecting the current operation zone of the elevator when an auxiliary power supply driving situation occurs; and operating the elevator by using the auxiliary power supply to correspond to the detected current operation zone. The detected current operation zone corresponds to one of an acceleration zone, a constant speed zone, a creep zone and a seating zone.
