ELEVATOR SYSTEM

摘要

An elevator system to continue communication even if a tracking error exists and to reduce interference on other transponders when transmitting a video and audio between an endstation facility and another endstation facility via a transponder mounted on communications satellite. This transmission system includes a tracking antenna that tracks a transponder, a tracking error calculation circuit that obtains a tracking error in a tracking operation of the tracking antenna, a transmission level control circuit that obtains a transmission level of a signal in response to the tracking error, and a transmitter that transmits the signal at the obtained signal level via the tracking antenna to the transponder of the communication target.

主权项

1. An elevator system comprising:
a group control device which performs group control of a plurality of elevator devices; and a destination call registration device, installed in an elevator hall, by which a passenger registers a destination call in the hall, wherein each of the elevator devices includes a plurality of cars that ascend and descend in the same shaft, and wherein the group control device includes:
a first determination unit which tentatively assigns a call newly registered from the destination call registration device to a first car, and excludes the first car from candidate cars of a first group in a case where a second car arranged above or below the first car stops at the hall before the first car; andan assigned car determination unit which selects a car to which the new registration call is assigned from the candidate cars of the first group.
