Abstract
According to an aspect, there is provided an elevator communication system. The system comprises an ethernet bus, at least one message forwarding element connected to the ethernet bus and being configured to communicate with a control entity that is external to the elevator system, and at least one elevator system component configured to communicate via the ethernet bus and being provided with an ethernet medium access control address. The at least one elevator system component is configured to at least one of receive an ethernet frame from the control entity and to send an ethernet frame to the control entity.
Claims14
An elevator communication system configured to facilitate communication for an elevator system, the elevator communication system comprising:
- an Ethernet bus;
- a message forwarding element connected to the Ethernet bus, the message forwarding element configured to communicate with a controller, the controller being external to the elevator system, the controller being one of a building manager, a building automation control entity, a cloud control entity, a remote server, or a service center;
- and
- at least one elevator system component having an Ethernet medium access control address assigned thereto, the at least one elevator system component configured to exchange an Ethernet frame with the controller via the Ethernet bus using the message forwarding element such that the elevator system component is directly addressable by the controller via the Ethernet medium access control address allowing the controller to directly address and control the at least one elevator system component and the at least one elevator system component to directly send data to the controller.
An elevator communication system configured to facilitate communication for an elevator system, the elevator communication system comprising:
- an Ethernet bus;
- a message forwarding element connected to the Ethernet bus, the message forwarding element configured to communicate with a controller, the controller being external to the elevator system;
- and
- at least one elevator system component having an Ethernet medium access control address assigned thereto, the at least one elevator system component configured to,
- exchange an Ethernet frame with the controller via the Ethernet bus using the message forwarding element, and
- set to a high-impedance state in response to other ones of the at least one elevator system component of a same multi-drop Ethernet bus segment being active.
