Abstract
According to an aspect, there is provided an elevator communication system. The system comprises an elevator controller, a multi-drop ethernet bus segment reachable by the elevator controller, and a plurality of elevator system nodes connected to the at least one multi-drop ethernet bus segment configured to communicate via the multi-drop ethernet bus, wherein the elevator controller is reachable by the elevator system nodes via the multi-drop ethernet bus segment.
Claims26
An elevator communication system, comprising:
- an elevator controller;
- at least one multi-drop Ethernet bus segment including an elevator car segment installed within an elevator car and reachable by the elevator controller;
- at least one point-to-point Ethernet bus including a first point-to-point Ethernet bus within a travelling cable of the elevator car;
- at least one network connecting device, the at least one network connecting device including a network connecting device within the elevator car and having a first port connected to the elevator car segment of the at least one multi-drop Ethernet bus segment and a second port connected to the first point-to-point Ethernet bus;
- and
- a plurality of elevator system nodes connected to the at least one multi-drop Ethernet bus segment, the plurality of elevator system nodes configured to communicate via the at least one multi-drop Ethernet bus segment such that the elevator controller is reachable by the plurality of elevator system nodes via the at least one multi-drop Ethernet bus segment.
A method for introducing a new elevator system component to an elevator control system, the method comprising:
- connecting the new elevator system component to an elevator system bus node connected to a multi-drop Ethernet bus segment installed within an elevator car and associated with an Ethernet bus included in the elevator control system, the elevator system bus node being one of a plurality of elevator system bus nodes, and the Ethernet bus including at least one point-to-point Ethernet bus including a first point-to-point Ethernet bus within a travelling cable of the elevator car, the elevator system bus node being connected to a first port of a network connecting device within the elevator car and the first point-to-point Ethernet bus being connected to a second port of the network connecting device;
- and
- transmitting operational characteristics and a network address of the new elevator system component from the elevator system bus node to a configuration controller via the network connecting device and the Ethernet bus, wherein the configuration controller is configured to generate configuration data based on the operational characteristics and the network address of the new elevator system component.
