摘要: In a two-way ring elevator communications system, characterized in that controller is associated with each to process inter-elevator messages and the controllers of elevators are linked together serial fashion on system so passed along processed by other two directions independent rings, whichever rings properly functioning used at full capacity but if neither then both operated reduced capacity, reduction being carried out reducing time between reassignments hall calls.
