The invention relates to an elevator group-control device for controlling a plurality of cars in a double-deck elevator system in which a plurality of cars are operated in a coupled manner in a single hoistway, or in a one-shaft multi-car system in which a plurality of cars are operated independently in a single hoistway.
In a conventional elevator group-control device for a double-deck elevator, for example, at an upward operation, when a same-direction assignment detection means detects that an up landing call of the 6th floor is assigned to an upper car and an other-car car-call presence/absence determining means determines registration of a car call of the 6th floor for a lower car, an assignment changing means changes the assignment of the up landing call of the 6th floor from the upper car to the lower car to deal with both calls by a single stop (for example, refer to Patent Document 1).
Patent Document 1: Japanese Unexamined Patent Publication No. H08-259126
In a conventional elevator group-control device for a double-deck elevator or a one-shaft multi-car elevator, by the change in assignment afterward, a landing call for and a car call of a lower car or an upper car are managed to be assigned to either one of the cars. However, in a system in which a destination floor call is registered by inputting a destination floor at a hall, an assigned car is informed to each user when a destination floor is inputted at a hall, and the assignment cannot be changed afterward. Therefore, there has been a problem that the conventional method cannot be adopted.
In addition, in a system in which a destination floor call is registered by inputting a destination floor at a hall, if a front car arrives in response to a car call and a landing call for the same floor and the same direction as the car call is assigned to a rear car in the same hoistway and if no means is provided for informing a user of whether the arriving car with the door opened is the front car or the rear car in the same hoistway, a case may occur in which a user who needs to board the rear car to which the landing call is originally assigned may erroneously board the car that has arrived at a car call destination in response to the car call. In general, in a system in which a destination floor call is registered by inputting a destination floor at a hall, a destination button is not installed in an elevator car or input of a destination car button in an elevator car cannot be registered in many cases, so that there has been a problem that only movement to a floor different from an intended destination floor may be possible or users may be trapped if a front car that users erroneously board stops for a last car call.
An elevator group-control device according to the invention includes a front-car car-call detection means 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 means 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 means.
An elevator group-control device according to the invention includes a rear-car assignment-candidate exclusion means for excluding a rear car in the same hoistway from assignment candidate cars when a front car in the same hoistway is assigned a car call and a landing call for the same floor and the same direction as the car call is registered. This allows a passenger to be prevented from erroneously boarding a car different from a car that the passenger should board and further allows for eliminating installation of a unit such as a display for informing a passenger of whether a currently arriving car is the upper car or the lower car to help the passenger avoid erroneously boarding the car.
Embodiment 1
Here, an operational flow will be explained assuming a case where a destination floor call 50 of the 7th floor for the 8th floor is newly registered. Using a front-car car-call detection means for detecting a car call of a front car with respect to its traveling direction or detecting a floor and a car that are assigned a destination floor of a registered destination floor call, the car 1A and the car call 11A for the 7th floor, the car 1A and the car call 12A for the 9th floor, the car 1A and the car call 13A for the 10th floor, and the car 2A and the car call 21A for the 11th floor are detected. Next, when a landing call for the same direction as the traveling direction is registered at a floor registered by the car calls detected by the front-car car-call detection means, by a rear-car assignment-candidate exclusion means that excludes, from assignment candidate cars, the rear car in the same hoistway as the front car that is assigned the car call, the front car 1A that is assigned the car call for the same direction and the same floor as the landing call of the 7th floor and the rear car 1B in the same hoistway are selected for the newly registered landing call of the 7th floor for the 8th floor, and the car 1B is excluded from the assignment candidate cars. The elevator group-control device selects an assignment car from other cars excluding the car 1B, dispatches the assignment car for the new destination floor call 50 of the 7th floor for the 8th floor, and displays the assigned car number in a liquid-crystal display part of an operational panel for registering a destination floor at a hall.
While the up car call 21B for the 7th floor assigns the same travel direction and floor as the new destination floor call for the 7th floor and is assigned to the lower car, i.e., not from a front car but from the rear car, the car 2B is not excluded from assignment candidate cars.
Next, an assigned car selecting method for the elevator group-control device according to Embodiment 1 of the invention will be explained using the flow chart of
Next, a system configuration of the invention will be described with reference to
It should be noted that, although the explanation has been made for an elevator group-control device for controlling a one-shaft multi-car elevator system in which a plurality of cars are operated independently in the same hoistway, the elevator group-control device may be for controlling a double-deck elevator system in which a plurality of cars are operated in a coupled manner.
The elevator group-control device thus configured eliminates arrival of the rear car in the same hoistway in response to a landing call for the same floor and the same direction as the front car after first arrival of the front car in response to a car call. This brings about an effect of preventing a passenger from erroneously boarding the car arriving in response to the car call and further brings about an effect of eliminating installation of a unit such as a display for informing a passenger of whether a currently arriving car is the upper car or the lower car to help a passenger avoid erroneously boarding the car.
Embodiment 2
Here, an operational flow will be explained assuming a case where a destination floor call 150 of the 5th floor for the 7th floor is newly registered. Using a rear-car landing-call detection means for detecting a floor and a car that are assigned a landing car call for a rear car with respect to its traveling direction, the up landing call 112B of the 7th floor for the car 1B is detected. Since the detected up landing call 112B and the destination floor call 150 are for the same upward traveling direction, and the destination floor of the destination floor call 150 and the floor of the up landing call 112B are the same 7th floor, the front car 1A that is in the same hoistway as the car 1B is excluded from assignment candidate cars by a front-car assignment-candidate exclusion means. The elevator group-control device selects an assignment car from other cars excluding the car 1A, dispatches the assignment car for the new destination floor call 150 of the 5th floor for the 7th floor, and displays the assigned car number in a liquid-crystal display part of an operational panel for registering a destination floor at a hall.
Next, an assigned car selecting method for the elevator group-control device according to Embodiment 2 of the invention will be explained using the flow chart of
The system configuration is the same as that of Embodiment 1, except that the rear-car assignment-candidate exclusion means in
It should be noted that, although the explanation has been made for an elevator group-control device for controlling a one-shaft multi-car elevator in which a plurality of cars are operated independently in the same hoistway, the elevator group-control device may be for controlling a double-deck elevator system in which a plurality of cars are operated in a coupled manner.
The elevator group-control device thus configured eliminates arrival of the other car in the same hoistway in response to a landing call for the same floor and the same direction as the car after first arrival of the car in response to a car call. This brings about an effect of preventing a passenger from erroneously boarding the car arriving in response to the car call and further brings about an effect of eliminating installation of a unit such as a display for informing a passenger of whether a currently arriving car is the upper car or the lower car to help a passenger avoid erroneously boarding the car.
Embodiment 3
Here, an operational flow will be explained assuming a case where a destination floor call 250 of the 4th floor for the 7th floor is newly registered. Using a front-car car-call detection means for detecting a floor and a car that are assigned a landing car call for a front car with respect to its traveling direction, the landing call of the 4th floor for the car 1A is detected. Since the detected landing call of the 4th floor for the car 1A is the same as the new destination floor call 250 in terms of the landing call floor and the traveling direction, and the car 1A is responding to the landing call with its door being fully opened, i.e., not in closing operation or not completely closed, the car 1B in the same hoistway as the car 1A is excluded from assignment candidate cars by a same-floor and upper/lower car assignment-candidate means. The elevator group-control device selects an assignment car from other cars excluding the car 1B, dispatches an assignment car for the new destination floor call 250 of the 4th floor for 7th floor, and displays the assigned car number in a liquid-crystal display part of an operational panel for registering a destination floor at a hall.
Although the car 1A has been already assigned a large number of car calls, and the cars 2A, 2B, 3A, 3B, 4A, and 4B need time to respond to the new destination floor call 250, the elevator group-control device selects an assignment car from the cars excluding the car 1B.
Next, an assigned car selecting method for the elevator group-control device according to Embodiment 3 of the invention will be explained using the flow chart of
The system configuration is the same as that of Embodiment 1, except that the rear-car assignment-candidate exclusion means in
It should be noted that, although the explanation has been made for an elevator group-control device for controlling a one-shaft multi-car elevator system in which a plurality of cars are operated independently in the same hoistway, the elevator group-control device may be for controlling a double-deck elevator system in which a plurality of cars are operated in a coupled manner.
In the elevator group-control device thus configured, the other car in the same hoistway as a car responding to a landing call will not be assigned to the landing call for the same floor and the same direction. This brings about an effect of preventing a passenger from erroneously boarding the car arriving in response to the car call and further brings about an effect of eliminating installation of a unit such as a display for informing a passenger whether a currently arriving car is the upper car or the lower car to help a passenger avoid erroneously boarding the car.
The present invention can be effectively utilized in appropriately determining an assignment car in an elevator group-control device for controlling a plurality of cars in a double-deck elevator system in which a plurality of cars are operated in a coupled manner in a single hoistway, and in a one-shaft multi-car system in which a plurality of cars are operated independently in a single hoistway.
