ELEVATOR COMMUNICATION ARRANGEMENT
摘要:
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 realtime 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.
