Abstract
In an elevator system in which a plurality of cars are operated in a coupled or independent manner in a single hoistway, an elevator group-control device includes a front-car car-call detection unit detecting a car call of a front car with respect to its traveling direction out of the plurality of cars or for detecting a floor and a car that are assigned a destination floor of a registered destination floor call; and a rear-car assignment-candidate exclusion unit excluding, from assignment candidate cars, a rear car in the same hoistway as the front car assigned the car call when a landing call for the same direction as the traveling direction is registered at a floor registered by the car call detected by the front-car car-call detection unit.
Claims3
In an elevator system in which a plurality of cars are operated in a coupled or independent manner in a single hoistway, an elevator group-control device comprising:
- a front-car car-call detection unit for detecting a car call of a front car with respect to its traveling direction out of the plurality of cars or for detecting a floor and a car that are assigned a destination floor of a registered destination floor call;
- and
- a rear-car assignment-candidate exclusion unit for excluding, from assignment candidate cars, a rear car in the same hoistway as the front car assigned the car call when a landing call for the same direction as the traveling direction is registered at a floor registered by the car call detected by the front-car car-call detection unit.
In an elevator system in which a plurality of cars are operated in a coupled or an independent manner in a single hoistway, an elevator group-control device comprising:
- a landing destination-floor registration unit for registering a destination floor call for a destination floor being input at a hall;
- a rear-car landing-call detection unit for detecting, out of the plurality of cars, a floor and a car that are assigned a landing call for a rear car with respect to its traveling direction;
- and
- a front-car assignment-candidate exclusion unit for excluding, from assignment candidate cars, a front car in the same hoistway as the rear car assigned by the landing call when a destination floor call for the same destination floor as the landing call and for the same direction as the traveling direction is registered at a floor registered by the landing call detected by the rear-car landing-call detection unit.
In an elevator system in which a plurality of cars are operated in a coupled manner or independent manner in a single hoistway, an elevator group-control device comprising:
- a landing call detection unit for detecting, out of the plurality of cars, a floor and a car that are assigned a landing call;
- and
- a same-floor and upper/lower car assignment-candidate unit for excluding, from assignment candidate cars, the other car in the same hoistway for a new landing call for the same floor and the same direction as the landing call, until a door of the landing call assigned car is in closing operation or is completely closed in response to the landing call at a floor registered by the landing call detected by the landing call detection unit.
