Abstract

PROBLEM TO BE SOLVED: To improve operation efficiency of a double deck elevator by providing an assignment changing means for changing an assigning means with vertically interconnected cars, when hall calls generated at a landing occur at continuous two floors. SOLUTION: During an operation of an elevator, a group managing/ controlling device 2 inputs signals of a car position, operation direction, and car call from a car control device 3, and a hall signal from a hall call button 6, and sequentially collects operation situations at a hall call floor. It compares a riding rate into a car in a learned specific state with a prescribed value, and changes an operation specification of the elevator responsive to the comparison result. In addition, it checks relation of hall call and car call of already recorded upper and lower cars to an assigned hall call, and in order to perform an efficient assignment for calls generated at two continuous floors, changes assignment so that the upper car 4A corresponds to a new hall call at a sixth floor and the lower car 4B corresponds to the hall call at a fifth floor.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a double-deck elevator, the control device including means for changing the allocation means by the same elevator car connected above and below the double-deck elevator.
In particular, the present invention relates to a control device for a double deck elevator suitable for reducing the waiting time of an elevator user of the double deck elevator at the time of congestion.

[0002]

2. Description of the Related Art Conventionally, as a method for controlling the operation of a double-deck elevator, a double-deck operation control method in which upper and lower cars are fixed to odd-numbered floors or even-numbered floors for service operation is the most common operation method. Widely known.

[0003] However, for various purposes, a function for operating a double-deck elevator by an operation method different from that described above has been studied.

[0004] The double-deck operation control method has an inconvenience that it cannot be used from an odd-numbered floor to an even-numbered floor. In particular, as in large office buildings in Japan, firefighting and crime prevention measures are emphasized, so the use of stairs to move between floors is completely hindered, and during working hours, open stairs or escalators are installed. 1 leading to the lobby
It is necessary to transfer at the first floor or the second floor.

[0005] Therefore, a double-deck operation control method is used during peak times of elevator users at work and during lunch when transportation capacity is insufficient, and during the other hours, a single deck is provided with only one of the upper and lower cars. There are cases where an operation method is adopted, and the operation method depends on time-based control or selection from a monitoring panel by a manager. For elevator users and managers, the single deck operation method is an operation that can operate both upper and lower cars efficiently because using only one of the upper and lower cars will lose the use value as a double deck elevator A method is needed. In Japanese Patent Application Laid-Open No. 9-221277, simultaneous service availability is recorded as a means for allocating a plurality of double-deck elevators when one of the upper and lower cars is stopped at a position where the other car can be opened. There is disclosed a control device for a double-deck elevator that includes storage means and changes the allocation method using data of the storage means for the allocation of the second floor where hall calls are continuous.

[0006]

In the planning of a building, it is very useful to operate an elevator having two cars in the same hoistway with high efficiency in view of the relationship between the area of the building site and the installation area of the elevator. That is what. However, in the case of the double deck elevator, when the upper car and the lower car stop once on the same floor, respectively, the waiting time of the elevator user becomes longer than that of operating with one car.

[0007] Therefore, the operation control method of the double deck elevator makes the most of its features, responds to hall calls on the second floor continuous with the upper and lower cars, and rides on the upper and lower cars respectively. Elevator users are required to improve efficiency by getting off at the same time with one stop.

An object of the present invention is to improve the efficiency of a single-deck operating method by changing the allocation of hall calls and car calls on a continuous two-story floor between upper and lower cars of a double-deck elevator control system. It is to strengthen the reliability of the control device.

[0009]

In order to achieve the above object, a storage section is provided for storing signals assigned to each of upper and lower cars of a double deck elevator control device. The most effective way to assign a double-deck elevator is to call a hall on a continuous second floor, or
For consecutive hall calls and car calls on the second floor, it is determined whether or not the upper car and the lower car change the allocation of the upper car and the lower car from the storage portion, and then execute. here,
If the assigned hall call becomes an assignment that degrades driving efficiency, such as that the upper car and the lower car stop once on the same floor for this optional double deck elevator, It has an assignment change function that can change the assignment to the elevators.

[0010] The present invention provides the above means,
When a hall call on the second floor or a hall call and a car call occur consecutively in the control device of the double deck elevator, the operation efficiency can be improved by changing the hall calls assigned to the upper and lower cars.

[0011]
