According to an aspect, there is provided an elevator communication system. The system comprises an elevator communication network configured to carry elevator system associated data; a plurality of elevator system nodes communicatively connected to the elevator communication network, wherein at least some of the plurality of elevator system nodes each comprises a camera associated with different landing floors, respectively, configured to provide image data about a respective landing floor area; and a controller communicatively connected to the elevator communication network and being configured to obtain image data from at least one camera during an evacuation situation; and provide, during the evacuation situation, to a node communicatively connected to the elevator communication network information for a graphical user interface comprising image data from a selected set of the cameras.

An application server is configured to receive first information associated with an elevator communication network configured to carry data associated with a plurality of elevator system nodes communicatively connected to the elevator communication network; and provide an application interface towards at least one client, the application interface enabling provision of at least part of the first information associated with the elevator communication network to the at least one client.

An elevator communication system includes an elevator communication network configured to carry elevator system associated data; a plurality of elevator system nodes communicatively connected to the elevator communication network, wherein at least some of the plurality of elevator system nodes each includes a camera associated with at least one of an elevator car configured to provide image data indicating whether a car door of the elevator car is open or closed and a landing floor configured to provide image data indicating whether a landing door of the landing floor is open or closed; an elevator car; and an apparatus communicatively connected to the elevator communication network and being configured to obtain image data from the camera during an evacuation situation; and provide, during the evacuation situation, to a node communicatively connected to the elevator communication network, the image data to enable the node to verify based on the image data that the car door and/or the landing door is closed before the elevator car is moved during the evacuation situation.

The invention relates to an elevator, comprising a hoistway with a plurality of hoistway sections attached to each other to provide a hoistway with a hoistway space, an elevator car arranged in the hoistway space to be vertically movable in the hoistway space between door openings at landings of a building, and doors at the door openings. In order to avoid problems caused by a mutual change of height of a hoistway and a building, a sensor provides to a control system a signal indicating a level difference between a first reference point of the hoistway and a second reference point of the building.

According to an aspect, there is provided an elevator communication system. The system comprises an elevator communication network configured to carry elevator system associated data and a plurality of elevator system nodes communicatively connected to the elevator communication network, wherein at least some of the plurality of elevator system nodes each comprises a camera associated with different landing floors, respectively, configured to provide image data about a respective landing floor area and wherein at least one of the plurality of elevator system nodes comprises a display arranged in an elevator car; and an apparatus communicatively connected to the elevator communication network, the apparatus being configured to receive an elevator call to a landing floor, and cause the display to display data provided by a camera associated with the landing floor in response to the elevator call to the landing floor.

Methods and systems for elevator control are provided. The methods and systems include receiving, by a computing device comprising a processor, a request for at least one service associated with an elevator system from a user device, controlling an elevator car to travel to a specific floor in accordance with the request, controlling an elevator car door to be closed upon arriving at the specific floor, transmitting an indicator to the user device that the elevator car has arrived at the specific floor, and controlling the elevator car door to open upon receiving, by the computing device, an access request from the user device.

According to an aspect, there is provided an elevator communication system. The system includes an elevator controller, a first ethernet bus portion connected to a first port of the elevator controller, a second ethernet bus portion connected to a second port of the elevator controller, and at least one elevator system node communicatively connected to the elevator controller via the first ethernet bus portion and the second ethernet bus portion.

An elevator communication system includes a first elevator controller, a second elevator controller communicatively connected to the first elevator controller, a first ethernet bus portion connected to the first elevator controller, a second ethernet bus portion connected to the second elevator controller, and at least one elevator system node communicatively connected to the first elevator controller via the first ethernet bus portion and to the second elevator controller via the second ethernet bus portion.

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 (1), a message is used for control of a control target by being communicated in a common format between each of equipment servers (7) and each of object servers (9). The control target is a piece (3) of building equipment as a piece of equipment or an object (4) working in a building (2) as a facility.

An elevator installation has an elevator car that is moved in an elevator shaft between floors of a building under control of an elevator controller. The car has a first car door on a first car wall and a second car door on a second car wall. A first group of shaft doors is arranged in public zones of the building and a second group of shaft doors is arranged in non-public zones of the building. The elevator controller has a first operating mode in which the public zones are served; accordingly, only the first car door and the shaft doors for the public zones are actuated. In a second operating mode, the non-public zones are served, and accordingly only the second car door and the shaft doors for the non-public zones are activated.
