Document Type and Number:
Japanese Patent JP6569812
Kind Code:
B2
Abstract:
Provided is an elevator system whereby opening of a landing door at a floor other than a stopping floor of a cage can be detected even when a cage door and the landing door are open at the stopping floor of the cage. The elevator system is provided with: a plurality of landing doors, for each of which a door-opening-allowable zone is set; a plurality of second door-opening-allowable zone detection circuits for detecting entry of a cage of an elevator into a corresponding door-opening-allowable zone, the second door-opening-allowable zone detection circuits being provided so as to respectively correspond to the positions of the plurality of landing doors inside a hoistway; a plurality of landing-door-opening detection devices provided so as to respectively correspond to the positions of the plurality of landing doors inside the hoistway, and each having a landing-door-opening detection junction, the open/closed state thereof changing in response to the open/closed state of the corresponding landing door, the landing-door-opening detection devices short-circuiting both ends of the landing-door-opening detection junctions when the corresponding second door-opening-allowable zone detection circuit detects entry of the cage into the corresponding door-opening-allowable zone; and a control panel for detecting that a landing door other than the landing door for which the cage has entered the door-opening-allowable zone is open on the basis of the detection state of the second door-opening-allowable zone detection circuits and the state of the plurality of landing-door-opening detection junctions, the control panel being connected to wiring for connecting the plurality of landing-door-opening detection junctions in series.
