The invention relates to a method for generating an elevator call. The method comprises: obtaining (202) image data representing at least one symbol (310, 310a, 310b) illustrated on a symbol representing device (320) from at least one image sensing device (112), identifying (204) the at least one symbol (310, 310a, 310b) from the obtained image data, and generating (206) the elevator call in accordance with the identified at least one symbol (310, 310a, 310b). The invention relates also to an elevator control unit (108) and an elevator system (100) performing at least partly the method.

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 present invention relates to automatic elevator call control, and belongs to the field of elevator intelligent control technologies. An automatic elevator call system provided in the present invention calculates duration information from the moment when the personal mobile terminal leaves coverage of the wireless signal to the moment when the personal mobile terminal enters the coverage again, and when the duration information is less than or equal to a preset time threshold, causes the personal mobile terminal to be incapable of automatically sending an elevator call request command in a time period from the moment when the personal mobile terminal enters the coverage again to the moment when the personal mobile terminal leaves the coverage again. The present invention can effectively avoid invalid or abnormal elevator call request operations, and the elevator system achieves high running efficiency.

A building control system includes a plurality of interconnected building systems. A mobile application is configured to be installed on at least one mobile device. The mobile application is configured to cause the mobile device to interface with the building server and to display a graphical user interface (GUI). The GUI includes an elevator pane configured to allow a user to interface with a building elevator control system.

The invention refers to an arrangement for the allocation of destination calls in an elevator system with at least two elevators, comprising a wireless transmitter device connected with an allocation control of the elevator system. The transmitter device interacts within a certain mutual distance with a wireless ID device carried by a passenger, which ID device is configured to transmit to the transmitter device an ID which is linked with a special transportation service in the elevator system. The elevator system comprises a memory with correlated operation parameters of the elevators which are linked to the particular special transportation service request of the ID device, whereby the ID device is configured to transmit ID data and/or a call with a departure floor and destination floor to the allocation control. The transmitter device is located within a transmitter accommodation space located at least in the vicinity of an elevator, whereby the transmitter device is located in the vicinity of a tag carrying a symbol correlated to the special transportation service.

The present invention relates to tracking of a passenger flow in an elevator car. A passenger flow tracking system for an elevator car according to the present invention includes: a first Bluetooth module installed in the elevator car, the first Bluetooth module being configured to broadcast a first Bluetooth signal that can substantially cover the interior of the elevator car and receive a response fed back by a personal mobile terminal carried by a passenger inside the elevator car; and a passenger flow determining unit configured to at least determine, based on a change in the received response, that the passenger leaves and/or enters the elevator car.

Communication for an elevator service request in the field of elevator technologies. A wireless signal device for broadcasting a wireless signal according to the present invention is capable of communicating with an elevator controller of an elevator system, establishing a wireless connection with a personal mobile terminal based on the wireless signal, receiving an elevator service request command from the personal mobile terminal, and sending the received elevator service request command to the elevator controller for elevator service control. The wireless signal device comprises: an elevator service request command responding unit configured to generate an elevator service request command data packet that has been responded to according to the elevator service request command that has been received; and a broadcasting unit configured to broadcast the elevator service request command data packet that has been responded to.

According to an aspect, there is provided a method and an apparatus for transmitting an elevator call. In the solution, a predetermined triggering event associated with a status of a vehicle is identified and transmission of the elevator call is caused based on the predetermined triggering event associated with the status of the vehicle.

An apparatus and a method are disclosed by which it is determined whether a receiver has received an object identifier, and wherein, in case the receiver has received the object identifier, entry control information is created based on the object identifier, and in case the receiver has not received the object identifier, the entry control information is created based on default information.

A method and system for controlling elevator dispatch is provided. User data, including user behavior, is collected from a number of users over a specified time period. Elevator use data for a number of elevators in a building is also collected over the specified time period. Applying the user data and elevator use data, an elevator dispatch model is constructed that predicts future elevator use according to predicted user needs. An elevator control system dispatches the elevators according to the dispatch model. The elevator dispatch model is refined according to feedback data collected from users over a subsequent time period.
