Definitions
- the present application relates to the field of elevator communication systems.
- an elevator controller may receive information from call buttons and then control an elevator drive to serve calls, or the elevator controller may receive information from a safety circuit and then based on this information control one or more entities of the elevator system. These are only some possible examples of situations where information is received and/or sent within an elevator system.
- an elevator system may comprise multiple different internal data transmission solutions. This may mean that multiple different communication stacks and multiple different physical layers may be used simultaneously. The use of multiple different internal data transmission solutions may result in a complicated and inefficient solution. Further, if a bus node, for example, a node disposed in a pit is connected to a communication bus enabling communication to an elevator controller, the communication bus may become faulty and thus communication from the bus node in the pit (for example, from the pit inspection station) towards the elevator controller may not be possible.
- an elevator communication system associated with a building comprising an elevator shaft.
- the elevator communication system comprises an ethernet bus, an elevator controller communicatively connected to the ethernet bus and configured to communicate via the ethernet bus, a plurality of connecting units disposed along the elevator shaft to implement the ethernet bus, at least one bus node disposed in the elevator shaft separated by a distance from the elevator controller and being communicatively connected to the ethernet bus and configured to communicate via the ethernet bus, and a second data channel separate from the ethernet bus, the second data channel establishing a direct connection between the at least one bus node and the elevator controller.
- the at least one bus node is disposed in a pit of the elevator shaft and the elevator controller is disposed in an upper part of the elevator shaft, in a landing of the upper part of the building, or in a machine room in the upper part of the building.
- a maintenance or an inspection device disposed in the pit such as pit inspection station, can be used for a maintenance and/or an inspection operation even in case of a malfunction of the primary bus, i.e. the ethernet bus.
- the second data channel comprises a separate ethernet bus section from the at least one bus node to the elevator controller.
- the second data channel comprises a separate wire loop between the at least one bus node and the elevator controller.
- the second data channel comprises a wireless data channel between the at least one bus node and the elevator controller.
- the at least one bus node comprises an inspection station.
- the various embodiments discussed below may be used in an elevator system comprising an elevator that is suitable and may be used for transferring passengers between landing floors of a building in response to service requests.

For example, the bus node 102C may be disposed in a pit of the elevator shaft and the elevator controller 100 be disposed in an upper part of the elevator shaft, in a landing of the upper part of the building, or in a machine room in the upper part of the building.
- the elevator controller 100 may be disposed in the lower part of the building.
