A system and method for remotely monitoring the operation of elevators to determine elevator shutdown. A control box is mounted to each elevator that includes one or more sensors that can detect movement of the elevator, a processor that can process data received from the sensors and a communications device that can transmit the processed data. The method includes determining a usage rate of movement of each of the elevators in the processor using the data, transmitting the usage rate from each of the communications devices to a remote server, and comparing the usage rate of each of the elevators to the usage rate of the other elevators in the server. The method then determines that one of the elevators has shut down or has a low performance if its usage rate is significantly different than the usage rate of the other elevators.

Provided is an elevator control device capable of calling attention to contact between a user and an autonomous moving body in an elevator shared by the user and the autonomous moving body. The elevator control device includes an elevator notification control unit configured to causes, based on a call for an elevator from an autonomous moving body, equipment provided in a hall of the elevator of a floor on which the autonomous moving body is present or equipment provided in a car of the elevator to provide notification of information indicating that the autonomous moving body boards or disembarks from the car.

An elevator shaft element, an elevator arrangement and a method. The elevator shaft element comprises a frame module arranged for receiving an elevator car therein. The frame module is constructed from a transport and/or storage unit, comprising side walls, a bottom wall and a roof wall. The unit is arranged to be positioned vertically such that said side walls, bottom wall and upper wall of the unit define an inner space of the elevator shaft. Elevator car guides for guiding movement of the elevator car in the elevator shaft element are attached to said bottom wall and/or roof wall.

According to an aspect, there is provided a method for determining the number of elevator cars in a two-shaft multi-car elevator system. The method comprises determining the number of active elevator cars N in the two-shaft multi-car elevator system by

[00001]$N=\frac{\mathrm{RTT}*\mathrm{arr}}{a*\mathrm{carsize}},$

wherein RTT is a round trip time of the two-shaft multi-car elevator system, arr is the arrival rate of passengers, a is a car load factor, and carsize is the number of passengers one elevator car is able to carry.

A method of establishing a range restriction for calling an elevator car through a mobile device is provided. The method comprising: displaying a map of a desired building on a manager device; adjusting the range restriction using the manager device, wherein the range restriction limits elevator calls to mobile devices located within a selected range of the desired building; receiving an elevator call from a mobile device, the elevator call including a geographical location of the mobile device; and moving the elevator car in response to the elevator call when the geographical location of the mobile device is within the range restriction limits.

Methods for determining an absolute position of a moving travel unit of a stationary transport system, the travel unit movable along a travel path inside the system. The travel unit is driven by at least one linear motor along the path. The linear motor is a synchronous motor including a plurality of stator units installed along the travel path configured to provide a magnetic field traveling along the travel path. At least one rotor unit is attached to the travel unit and is configured to be driven along the travel path by the traveling magnetic field. Wherein respectively by analysis of regulating parameters of a vector regulation of the linear motor an active stator unit is determined from the plurality, which presently provides the magnetic field driving the rotor unit and a relative position of the rotor unit in relation to the active stator unit is computed.

A method of establishing a range restriction for calling an elevator car through a mobile device is provided. The method comprising: displaying a map of a desired building on a manager device; adjusting the range restriction using the manager device, wherein the range restriction limits elevator calls to mobile devices located within a selected range of the desired building; receiving an elevator call from a mobile device, the elevator call including a geographical location of the mobile device; and moving the elevator car in response to the elevator call when the geographical location of the mobile device is within the range restriction limits.

Methods and systems for making elevator service requests in a building. The method including obtaining a floor plan for the building and overlaying a measurement system of suitable scale onto the floor plan. The method also includes identifying relevant features and their location in the floor plan based on the measurement system, determining a pathway from a user device to a target area in the vicinity of an elevator door based on the relevant features, and computing a travel duration from the user device to the target area. Finally, the method includes assigning an elevator car to a user based on a user service request at the user device and the travel duration.

Lift systems may include a first shaft unit and a second shaft unit, each of which may include a number of lift shafts. One or more single-car systems and/or multi-car systems may be disposed in the first shaft unit, whereas one or more shaft-changing multi-car systems may be disposed in the second shaft unit. A transporting operation may be carried out from an initial floor to a destination floor wherein a control unit determines whether to utilize one or more cars from the single car systems, the multi-car systems, the shaft-changing multi-car systems, or some combination thereof depending on factors such as the destination floors of the passengers, traffic density, energy demand, and/or availability of cars.

A method of operating a dispatcher of an elevator group of a building elevator system having a plurality of elevator systems organized into multiple elevator groups including: receiving an elevator call, the elevator call including a desired destination; transmitting elevator status data from the elevator group to one or more other elevator groups of the building elevator system; receiving elevator status data from each of the one or more other elevator groups of the building elevator system; determining a verdict depicting whether an elevator car of the elevator group is best to serve the elevator call in response to the elevator status data of each of the one or more other elevator groups of the building elevator system; and calling an elevator car in response to the verdict.
