A method of operating a building elevator system having a plurality of elevator systems organized into an elevator group including: detecting crowd data within an elevator lobby proximate the elevator group on a landing; determining a level of crowdedness in response to the crowd data; determining at least two elevator cars of the plurality of elevator systems are required in response to the level of crowdedness; dispatching an elevator car of a first elevator system of the plurality of elevator systems to the landing; dispatching an elevator car of a second elevator system of the plurality of elevator systems to the landing; and coordinating an arrival time of the elevator car of the first elevator system at the landing and an arrival time of the elevator car of the second elevator system at the landing.

Provided is an elevator system capable of protecting the privacy of users. The elevator system includes: a plurality of in-car communication devices provided in a plurality of respective cars; and a group management device configured to, when an in-car communication device in a car that has arrived at a hall receives identification information from a portable terminal by wireless communication and when the car is not a car to which a call has been allocated on the basis of input from the portable terminal corresponding to the identification information, cause the in-car communication device in the car to transmit information indicating that a user has gotten on a wrong car to the portable terminal by wireless communication.

An illustrative example method of controlling an elevator system includes receiving a first request for elevator service from a requestor, receiving a second request for elevator service from the requestor while the first request is still pending, and controlling the elevator system to provide elevator service for only one of the first request or the second request.

Configuring stoppable floor information set for an elevator cabin of an elevator system. The elevator system of the present invention comprises an elevator cabin, an elevator control device and a wireless signal module which is configured to wirelessly receive a request of registering a destination floor from a passenger's personal mobile terminal and send a corresponding destination floor of the elevator cabin to the elevator control device based on the request of registering the destination floor; wherein the wireless signal module is further configured to obtain landing floor information corresponding to the elevator cabin from the elevator system, and the elevator system configures an stoppable floor information set corresponding to the elevator cabin based on the obtained landing floor information through a handheld terminal and/or the wireless signal module. The stoppable floor information set configured in the present invention is accurate.

The invention relates to a destination control system of an elevator system having at least one elevator group, wherein a destination call is input via at least one destination call input device to the destination control system to be allocated to at least one of the elevators of the elevator group to service the destination call. The destination call input device further includes an optional input for a desired operating time of a so called pre-booked destination call and the destination control system comprises a memory for pre-booked destination call data comprising the departure floor, the destination floor, a correlated operating time for the pre-booked destination call as well as a correlated identifier of the user having issued the pre-booked destination call, in which destination control system the pre-booked destination calls are allocated to the elevators of the elevator group with a higher priority than not pre-booked destination calls. Further, the destination control system has at least one identification reader arranged at least in the vicinity of the elevators to obtain an identifier input by the elevator user, and a pre-booked destination call is confirmed by the destination control system only after it has been checked that the identifier obtained by the identification reader corresponds to the identifier correlated to the pre-booked destination call. The invention rewards pre-booking of destination calls and leads thus to a better efficiency of the elevator system.

A method can be used to operate an elevator system that comprises multiple elevator shafts, an elevator car, and a shaft changing unit. The elevator car can change from a first elevator shaft into a second elevator shaft by way of the shaft changing unit. To convey a user of the elevator system from a starting position to a destination position, a route is determined from a plurality of route options whereby initial values are taken into account for the determination of the route. In this context, a specification relating to use of the shaft changing unit is taken into account as an initial value from the initial values for the determination of the route.

An elevator system having a controller configured for: receiving a communication from the mobile device for a passenger, the communication including first data, wherein the first data is position data obtained by the mobile device executing a multilateration (MLAT) process with one or more proximately located telecommunication devices, rendering a first determination, from the first data, that the mobile device is proximate a first distance from the lobby, rendering a second determination, from the first determination, arrive at the lobby proximate a first time, and transmitting a communication to an elevator instructing the elevator to arrive at the lobby proximate the first time to provide elevator service.

The invention relates to a remote monitoring system for an elevator system. The remote monitoring system comprises at least one remotely operable intermediate device and a monitoring unit for remotely controlling operation of the at least one intermediate device at least partly. The monitoring unit is configured to: control at least one intermediate device to generate a remote com-mand for controlling at least one operation of the elevator system, and monitor a response of the elevator system to the remote command. The invention relates also to a method for remotely monitoring an elevator system.

An elevator system including an elevator controller configured for: effecting a first communication with a mobile device to receive data from an electronic calendar that is activated on the mobile device, rendering a plurality of determinations from the first communication, including: a first determination that a first entry in the electronic calendar indicates that a passenger associated with the mobile device has a first scheduled event that occurs at a first scheduled time, a second determination to effect elevator service proximate to the first scheduled time to the passenger, and effecting a second communication with the elevator car to thereby effect the second determination.

A method of calling an elevator car from a mobile device is provided. The method comprising: receiving a first elevator call from a first mobile device on a first floor, the first elevator call including a destination request to travel to a second floor; moving an elevator car to the first floor in response to the first elevator call; detecting whether the first mobile device is within the elevator car at the first floor; and adjusting operation of the elevator car in response to each mobile device detected within the elevator car.
