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.

The invention comprises a method and a system for conveying a mobile robot in an elevator involving the monitoring of elevator operating components and of persons surrounding the elevator and operating the elevator by selecting a floor to which the mobile robot is to move. In one aspect an inertial sensor is used to learn or determine the number of floors. The robot may also have methods implemented to assess the floor space inside the elevator or to position itself in front of the elevator in such a way that it can, for example, monitor the operation of elevator operating components without being perceived as an obstacle from the elevator users' perspective.

There are provided a communication system in which a piece of equipment in a facility and a device working in the facility cooperate easily with each other, an equipment server and a device server in the communication system, and a data structure which is to be communicated in the communication system. In a communication system, a message is used for control of a control target by being communicated in a common format between each of equipment servers and each of object servers. The control target is a piece of building equipment as a piece of equipment or an object working in a building as a facility.

An illustrative example embodiment of an elevator system includes a destination entry device configured to allow a passenger to indicate an intended destination prior to entering an elevator car and at least one detector configured to detect a proximity between the passenger and at least one other individual that has not indicated an intended destination. A controller is configured to determine whether the detected proximity between the passenger and the at least one other individual satisfies at least one criterion indicating that the at least one other individual likely is associated with the passenger, will board an elevator car with the passenger, and will travel to the intended destination with the passenger. The controller is configured to assign an elevator car to carry the passenger and the at least one other individual to the intended destination when the detected proximity satisfies the at least one criterion.

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.
