An elevator system drive includes: an electric machine: a first converter electrically connected to an alternating current source and the electric machine: a drive controller controlling the drive: a drive safety circuit unit electrically connected to a safety circuit of the elevator system, to a controller of the elevator system, and to the drive controller; and at least one mechanical brake that is closed by a brake closing command from the elevator system controller. The drive safety circuit unit operates in a first operating state wherein it transmits an emergency stop command coming from the elevator system safety circuit directly and without delay to the first converter, and operates in a second operating state wherein it relays a modified emergency stop command coming from the elevator system safety circuit, with a delay, to the first converter to ensure safe braking of the elevator system even if the mechanical brakes fail.

A method of operating a building elevator system within a building having a plurality of landings including: controlling a first elevator group; controlling a second elevator group; adjusting a range of landings served by one or more elevator systems of the second elevator group in response to at least one of the predicted passenger response time, the time of day, the amount of traffic received by the first elevator group, the amount of traffic received by the second elevator group, the amount of traffic within the first range of landings, the amount of traffic within the second range of landings, the amount of traffic received by the first elevator group relative to the amount of traffic received by the second elevator group, and the amount of traffic within the first range of landings relative to an amount of traffic within the second range of landings.

According to an aspect, there is provided a control device. The control device is configured to receive data from a passenger traffic system configured in a building, the data comprising information associated with operations for transferring passengers of the passenger traffic system; based on the received data, monitor a change in a quality of service level of the passenger traffic system in transferring the passengers and a change in a passenger traffic pattern in transferring the passengers in the passenger traffic system; and in response to detecting the change in the service level or in the passenger traffic pattern, run one or more simulations of the passenger traffic in the passenger traffic system in the at least one building using the received data in order to trigger at least one operation to change a configuration of the passenger traffic system.

A method of operating a building elevator system within a building having a plurality of floors including: controlling a building elevator system comprising a first elevator system having a first elevator car and a second elevator system having a second elevator car; determining one or more sectors for the plurality of floors in response to at least one of a time of day, manual input, a density of the down peak traffic, and whether there is simultaneous up peak or inter-floor traffic, the one or more sectors comprising a first sector having a first plurality of floors and a second sector having a second plurality of floors; assigning the first elevator car to the first sector; and assigning the second elevator car to the second sector.

A method of collecting data using a robot data collection system including: collecting data on a landing of a building using a sensor system of a robot; transmitting the data to a conveyance system of the building; and adjusting operation of the conveyance system in response to the data.

A method of operating a shuttle elevator group including: detecting an arrival of an elevator car at a landing; determining a time since a previous elevator car departed the landing; determining a fullness percentage of the elevator car; determining an estimated time until a next elevator car arrives at the landing; and determining when the elevator car departs the landing based upon at least one of the fullness percentage of the elevator car, the time since the previous elevator car departed the landing, and the estimated time until the next elevator car arrives at the landing.

A method of operating a building elevator system within a building having a plurality of floors including: controlling a building elevator system comprising a first elevator system having a first elevator car and a second elevator system having a second elevator car; determining one or more sectors for the plurality of floors in response to at least one of a time of day, manual input, a density of the down peak traffic, and whether there is simultaneous up peak or inter-floor traffic, the one or more sectors comprising a first sector having a first plurality of floors and a second sector having a second plurality of floors; assigning the first elevator car to the first sector; and assigning the second elevator car to the second sector.

An aspect includes capturing crowd data associated with a lobby area of an elevator system. A dispatching schedule of one or more elevator cars of the elevator system is adjusted based on the crowd data. A notification of the adjustment to the dispatching schedule is output.

Embodiments herein relate to an elevator system of a facility with multiple floors. The elevator system can comprise elevator cars and an elevator controller. The elevator controller includes a memory and a processor. The memory stores computer program instructions executable by the processor to cause the elevator system to determine a current utilization of the elevator system, automatically activate an adaptive split group operation on a per floor basis when the current utilization of the elevator system is greater than a threshold utilization of the elevator system, and dispatch the elevator cars under the adaptive split group operation in accordance with elevator calls.

The invention relates to a method for allocating elevators of an elevator group to landing calls given in the elevator group, the elevator group having a control unit having a destination call control, which elevator control unit is connected to determining means for the prevailing traffic condition in the elevator group. Further the control unit comprises at least a first and second operating mode which are selected according to the prevailing traffic condition, wherein the first operating mode uses immediate call allocation of the elevators which includes the display of the allocated elevator on a destination operating panel immediately after having issued a landing call and wherein the second mode comprises the allocation of an elevator to a landing call before the arrival of the allocated elevator call to the landing where the landing call has been issued. The invention allows an adaption of destination control to different traffic situations.
