Abstract: An elevator system includes an elevator car (28) disposed in and constructed and arranged to move along a hoistway (26) generally defined by a stationary structure. A short-range communication system of the elevator system is configured to provide communication between the elevator car and the stationary structure, and may include a transceiver (62, 64) carried by the elevator car and a plurality of transceivers (66) spaced along the hoistway. A network coordinator (68) of the communication system is operatively coupled to the plurality of hoistway transceivers to provide uninterrupted communication.

Abstract: Methods and systems of controlling elevators including detecting a landing stop for an elevator car, measuring load information associated with the stop, controlling stopping of the elevator at the landing using a machine based on at least one of the detected landing and the measured load information and performing dynamic compensation control of a motion state of the elevator with a computing system and the elevator machine. The dynamic compensation control includes receiving motion state information related to at least one motion state of the elevator car at the computing system, receiving the landing and load information at the computing system, applying a filter to the received information and generating a first control signal, and producing a control output from the first control signal to control the elevator machine to minimize oscillations, vibrations, excessive position deflections, and/or bounce of the elevator car at the detected landing.

Abstract: A ropeless elevator system (10) includes a plurality of elevator cars (14) configured to travel in a hoistway having at least one lane (13, 15, 17), a propulsion system (16, 18) to impart force to each elevator car of the plurality of elevator cars, and a controller (46). The controller is configured to operate in an in-group mode where the plurality of elevator cars perform service demands, and to selectively operate in an out-of-group mode where at least one selected elevator car of the plurality of elevator cars performs a predetermined task and is prevented from performing the in-group mode service demands.

Abstract: A method for controlling car separation in a multi-car elevator system, the method including: initiating, by a controller, a change in a profile of a target elevator car; determining that N elevators cars are affected by the change in the profile of the target elevator car, wherein elevator car N is an elevator car farthest from the target elevator car; calculating for each of the N elevator cars an updated profile; for each of the N elevator cars, beginning with the Nth elevator car and ending with the target elevator car, performing: determining if the updated profile for the elevator car will provide separation between the elevator car and a neighboring elevator car; and when the updated profile for the elevator car will provide separation between the elevator car and the neighboring elevator car, executing an elevator car profile update process for the elevator car.

Abstract: A service tool function availability adjustment system includes a storage medium operable to store a location-based function availability map and at least one processor configured to determine a location of a service tool in relation to one or more equipment components of an equipment service system. The at least one processor configures an availability of one or more functions of the service tool to interact with the one or more equipment components of the equipment service system based on the location-based function availability map and the location of the service tool.

Abstract: An elevator component separation assurance system includes a controller, and a brake controller. The controller includes an electronic processor, a computer readable storage medium, a safety motion state estimator, and a safety assurance module. The safety motion state estimator is configured to identify velocity and position of each one of a plurality of elevator components. The safety assurance module is configured to select a separation map from a plurality of pre-pre-programmed separation maps for each one of an adjacent component pair of the plurality of elevator components for initiating a Ustop that maintains elevator component separation. The brake controller is carried by each one of the plurality of elevator components, and is configured to actuate a secondary brake upon detection of a loss of communication with at least a portion of the controller.

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.
