  • Patent number: 10435271
    Abstract: Elevator safety and safety related information needs to be sent reliably to safety controlling systems. Existing elevator communication devices may be used for transmitting this information by processing the received safety and safety related information and processing it before sending it over the communication bus from the elevator car or floor equipment to the controlling devices. A separate communication unit may be used for receiving and processing safety and safety related data packets before they are transmitted over a common bus used for safety and safety non-critical submission.

  • Publication number: 20190062103
    Abstract: Conventionally, elevator communications have been implemented using travelling cables. This is particularly the case when safety related data transmitted from an elevator car has to fulfil real-time restrictions often set by regulators so that the receiving of the information may not be delayed. Typically, this cannot be guaranteed when wireless transmission technologies are used. The reliability can be increased by using a second to supplement the wireless transmission.
