Elevator system passengers are transported in one or more of a plurality of elevator cars. The elevator cars can require different amounts of energy to operate. Passenger trips can be allocated to one car or another car based on the expected energy consumption for the trips in one or the other car.

An electronic elevator guard device that monitors a set of integrity states of a plurality of elevator features includes at least one sensor in an elevator and configured for monitoring at least a first of the integrity states and generating a first monitoring signal based on a sensed current status of the first integrity state. The guard device includes a questioning device having or communicating with a human-machine interface and configured for asking predetermined questions to a consulted person and for receiving the person's answers via the human-machine interface, the questions relating to at least a second of the integrity states, and generating a second monitoring signal based on at least one answer. The guard device includes an evaluation device configured for generating an overall monitoring signal based on the first and second monitoring signals and sending the overall signal to a remote recipient via a communication device.

An information processing apparatus includes a controller configured to predict a state of congestion of an elevator installed in a building and generate, based on the predicted state of congestion, a proposal message to propose a departure time for the building to a user planning to travel to the building.

According to an aspect, there is provided a method for elevator call allocation in an elevator group comprising a plurality of elevator cars. The method comprises detecting a logistic operation associated with an elevator car, the elevator car being stationary at a floor, and limiting allocation of new elevator calls to the elevator car in the elevator group in response to detecting the logistic operation.

A method, system, and computer program product for occupant-based elevator actions are provided. The method identifies a set of subjects approaching a set of elevators to generate a set of identities for the set of subjects. A set of initial priority statuses are generated for the set of subjects. Based on the set of identities and the set of initial priority statuses, an elevator dispatch solution is determined. The method updates at least a portion of the initial priority statuses to generate a set of subsequent priority statuses in response to a subset of subjects entering at least one elevator. The method determines an isolation response for a first subject of the subset of subjects and modifies the elevator dispatch solution based on the isolation response to generate an isolation dispatch solution. The at least one elevator executes the isolation dispatch solution.

The invention relates to a method for controlling an elevator. In the method at least one control signal is generated for instructing the at least one mobile robot to a predetermined position. The at least one mobile robot generates at least one control signal to the elevator controller for controlling an elevator in response to an interaction with at least one user in the predetermined position. The invention also relates to an elevator system and a mobile robot implementing at least portions of the method.

To provide an elevator group management device that can accurately present information about learning of operational efficiency of an elevator. The elevator group management device includes a traffic-flow estimating unit configured to estimate a traffic flow based on boarding and alighting floors of users and a number of boarding and alighting people of an elevator, a learning unit configured to determine a policy of running of a car based on the traffic flow estimated by the traffic-flow estimating unit, a simulation unit configured to evaluate operational efficiency at the time when the car is virtually run based on the policy determined by the learning unit, and a display control unit configured to cause an information display device to display information indicating a status of learning by the learning unit and the simulation unit.

A car mover for autonomously moving an elevator car along a lane in a hoistway, including: first and second wheels of the car mover, configured to apply a pinch force against a track therebetween and to rotationally drive along the track, by respective first and second wheel motors of the car mover; and a controller configured to execute: a lateral clearance control self-learning module, wherein based on adjustment data, one or more operational parameters applied by one or more of the first and second wheel motors are adjusted; and a lateral clearance feedback control module, wherein based on one or more of a first lateral clearance adjacent the first wheel on the track and a second lateral clearance adjacent the second wheel on the track, torque applied by one or more of the first and second wheel motors is increased or decreased.
