Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation control device for a double-deck elevator, and more particularly to an operation control device for deciding a double-deck elevator to efficiently service a user's usage request from a hall.

[0002]

2. Description of the Related Art In order to increase the effective use area in a building, there is a method of reducing the hoistway area by adopting a double deck elevator having vertically connected cars.

The operation system of this double-deck elevator is roughly classified into a system that restricts the stop floor to an even floor of the upper car and an odd floor of the lower car, and a system in which upper and lower cars are freely serviced to each floor, the latter. Although the method of (1) is convenient and convenient for the user as it is a normal single-deck elevator, compared to the former method, the number of times of stopping is large and the efficiency is slightly inferior.

Therefore, Japanese Patent No. 1616619 et al. Discloses a method of reducing the number of stoppages by servicing consecutive floors at the same time in upper and lower cars.

Further, in Japanese Unexamined Patent Publication No. 8-198529, based on the allocation evaluation value of each of the upper and lower cars, an extra waiting time due to the influence of the other connected car (the other car) is used as the allocation evaluation index. We are allocating.

[0006]

In the above-mentioned prior art, Japanese Patent No. 1616619, the consideration of the other car is made, but the consideration is that the two adjacent floors are in the same direction. If there is an assignment command for the landing call of the car and / or the car floor call and the hall call match, other factors such as waiting time of the other car and prediction of congestion in the car are considered. Not not.

Further, in Japanese Unexamined Patent Publication No. 8-198529, there is a call to the other party car which is stopped for getting on and off the other car even though there is no car interior call or landing call. However, only the car itself waited by the other car is taken into consideration, and the waiting time of the other car is not taken into consideration.

The object of the present invention is to evaluate not only the evaluation value of the target car itself (hereinafter referred to as its own car) but also the evaluation of the other car connected to the target car (hereinafter referred to as the other car). By evaluating and allocating it, the operation control will be performed while taking into consideration the influence of the partner car unique to the double deck elevator.

The resulting object of the present invention is to provide a highly efficient operation control device for a double deck elevator.

Another object of the present invention is to provide an operation control device capable of processing when a double-deck elevator and a single-deck elevator are mixed, or when a single-deck operation and a semi-double-deck operation are mixed.

[0011]

[Means for Solving the Problems] In order to achieve the above object, a plurality of double-deck elevators having vertically connected cars, a hall calling means for accepting a user's usage request, and a usage request When deciding a double-deck elevator to be serviced as a service, an allocation means is provided for each car of each unit that uses an evaluation value that simultaneously considers the evaluation value of its own car and the evaluation value of the other car.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a system configuration according to an embodiment of the present invention.

A plurality of double deck elevator machines 1
0 has an upper car 11 and a lower car 12, which are vertically connected cars. The unit control device 13 runs, stops, opens and closes the double-deck elevator unit 10.

A plurality of double deck elevator machines 1
The operation control device 20 that performs 0 operation has the arrival state prediction unit 2
1 and an assigned car determination unit 22 corresponding to the assigning means which is the main point of the present invention.

A hall call button 30 is provided in the elevator hall on each floor to receive a use request from a user. Further, the service guide lamp 31 informs the user of which of the plurality of double-deck elevator machines 10 will service the usage request.

The use request signal input by the user operating the hall call button 30 is transmitted to the operation control device 20.
The operation control device 20 receives a car status signal such as the position of each double-deck elevator car 10 and the number of people in the car from the machine control device 13, and each car of the double-deck elevator 11 to the floor where the user who issued the usage request signal waits. , 12 arrival states are predicted in consideration of the own car waiting time evaluation value and the partner car waiting time evaluation value, the car to service the user is determined, and the assigned car signal is transmitted to the service information lamp 31. And inform the user. The assigned car signal is also transmitted to the machine control device 13 corresponding to the assigned car.

In the description of the present embodiment, only the essential parts of the present invention will be described in detail, and the description of the parts to which the publicly known and publicly-known technology can be applied in the normal single-deck elevator operation control device will be omitted. .

FIG. 2 is a flow chart for explaining one embodiment of the operation control processing 100 executed by the operation control device 20.

The operation control processing 100 is, for example, 100 m.
It is assumed to be activated periodically such as s or in response to a use request signal from the user.

Here, steps 111 to 112 are processes in the arrival prediction unit 21, and steps 121 to 131 are assigned car determination units 22.
Is a process corresponding to.

In step 111, each unit control device 13
It receives a car status signal such as the position of each double deck elevator machine 10 and the number of people in the car.

In step 112, each of the double-deck elevators 11 and 1 using the acquired upper and lower car state signals.
2, estimated arrival time to each floor, each upper and lower car 11 on each floor,
Estimate the number of people in 12 cars.

In step 121, it is confirmed whether or not there is a new usage request for which a car to be serviced has not been decided. Only when there is a new usage request in step 121,
The process proceeds from step 122 to step 131.

Steps 122 to 128 are loop processing for the car.

In step 122, the number of the car to be evaluated (own car) is i, and the number of the car (partner car) connected to the car is j, and the number of people in the car and the waiting time prediction data are calculated. Based on
1 (i) and Φ1 (j) are obtained.

At step 123, step 1 is performed at the relevant usage request floor based on the number of people in the car predicted at step 112.
Check whether 22 of the own car i and the other car j are allocatable. The non-allocatable car here refers to a car that is closed during single-deck operation, a car for a single-deck elevator, a full car, or a non-service floor. If both the own car i and the partner car j can be assigned, the process proceeds to step 124, and if at least one car cannot be assigned, the process proceeds to step 125.

In the present embodiment, the process of step 124 is the essential operation of the allocating means for determining the car to be serviced in response to the usage request. In this process, the car to be serviced is determined, but not only the car i concerned is evaluated and assigned. The evaluation values of both the own car i and the partner car j are simultaneously considered and evaluated, and the allocation is performed. At this time, the allocation is performed based on the predicted arrival time at the relevant floor predicted in step 112.

As one of the allocation methods, the car i
There is a method of taking the average of the larger of the waiting time evaluation value of 1 and the waiting time evaluation value of the other car and the waiting time evaluation value of the own car. The equation is shown in equation (1).

[0030]

Φ (i) = {max (Φ1 (i), Φ1 (j)) + Φ1 (i)} / 2 (1) Φ (i): the partner car of the car (i) Waiting time evaluation value Φ1 (i): Waiting time evaluation value Φ1 (j) of own car (i): Waiting time evaluation value of partner car (j) Here, the above waiting time evaluation value is, for example, This is for a new usage request.

In this evaluation formula, first, the waiting time evaluation value Φ1 (i) of the own car and the waiting time evaluation value Φ1 (j) of the other car.
By comparing with, the evaluation value that is predicted to have a long waiting time (large) is adopted. As a result, it becomes possible to evaluate the waiting time in consideration of the person with the longer waiting time. Moreover, by adding the waiting time evaluation value Φ1 (i) of the own car to this, it becomes possible to distinguish between the own car and the other car. Finally, dividing the sum of the two by 2 gives 1
The waiting time evaluation value per car can be obtained.

By using the value per one car, even when single deck elevators are mixed at all times or temporarily during group management, even when there are elevators performing single deck operation, fair allocation is made. It becomes possible to do. Of course, on the contrary, the waiting time evaluation value of the elevator operating using one car,
It is obvious that the waiting time evaluation value of the elevator operating using both cars can be weighted at an arbitrary ratio.

As another allocation method, there is a method of taking a weighted average of the waiting time evaluation value of the own car and the waiting time evaluation value of the other car. Equation (2) shows a generalized formula thereof.

[0034]

Φ (i) = {k * Φ1 (i) + Φ1 (j)} / (k + 1) ... Number (2) k: In the evaluation formula of the number of weighting factors (2), the waiting time of the own car Evaluation value Φ1
Normalized by adding the waiting time evaluation value Φ1 (j) of the opponent car to k * Φ1 (i) weighted on (i) and dividing by (k + 1) so that the evaluation value per car is obtained. Is. Thereby, it is possible to obtain the waiting time evaluation value per car in consideration of the partner car at an arbitrary ratio.

When the process proceeds to step 125, it is determined whether the full car is the own car, the other car, or both cars. If the full car is the other car, step 126
Proceed to and ignore the evaluation value of the other car and use the evaluation value of the own car that is not full as it is as the evaluation value. On the contrary, if the car is full, the process proceeds to step 127, and the evaluation value is set so that the car is prohibited from being allocated.

In step 128, it is judged whether or not the calculation process of the evaluation value Φ (i) has been completed for all the cars, and if not completed, the process is repeated from step 122 for the next car to obtain the evaluation values of all the cars. Then, the process proceeds to step 129, and the assigned hall call is assigned to the car i having the smallest evaluation value Φ (i).

Here, in step 123, the full car is separated from the step 124 because the allocation evaluation value of the other car is used in the allocation evaluation value, so that one car is full and the allocation evaluation value is large. This is because a value makes it difficult to assign a call even if the other car is not full.

Next, at step 130, an allocation signal is instructed to the car control device 13 of the car to which the car is allocated, and at step 131, the service guide lamp 31 corresponding to the car of the car on the floor is turned on.

Further, in the description of the present embodiment, a simple example is used because any assignment evaluation value Φ which determines the selection method of the assigned number does not conflict with the gist of the invention. In addition, I attach importance to the longest waiting time,
It is obvious that the present invention can be realized by using a method of performing weighted evaluation of a plurality of items such as the boarding time and the congestion degree in the car.

According to the present embodiment, the own car and the other car can be taken into consideration in the allocation process for deciding the allocated car, and more efficient operation control can be performed.

Further, according to the present invention, there is an effect that it is possible to select an assigned elevator for a double-deck elevator by utilizing software of a normal single-deck elevator control device.

[0042]

As described above, according to the present invention, it is possible to operate an efficient double-deck elevator in consideration of not only the evaluation value of the car but also the evaluation value of the car connected to the car. Has the effect of Further, there is an advantage that group management and maintenance work such as adjustment of various constants depending on the usage situation becomes easy.
