Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a multi-decker elevator in which a plurality of cars are vertically connected, and in particular, to a multi-decker elevator that can appropriately allocate cars to hall calls. It is related to.

[Background Art] In recent years, as buildings have become taller, the number of people living in the buildings has increased, and elevators with high transportation capacity have been required.

To deal with this, simply increasing the number of elevators increases the building area occupied by these elevators, reducing the effective usable area of the building. Therefore, multi-deck elevators with multi-story elevator cars are used.

As a conventional multi-deck elevator of this type,
A double deck elevator disclosed in Japanese Patent No. 1-1.2825 can be mentioned.

FIG. 4 is a schematic diagram showing a conventional double-decker elevator published in the publication No.

In the figure, (1) is an elevator car formed by connecting two cars vertically, and (2) is an I-
, the -1-car located on the side, and (3) the lower car located below. (4) is a hoist that raises and lowers the elevator car (1), (5) is a counterweight that balances the weight with the elevator car (1), and (6) is the elevator car (1).
It is a lobe that connects the counterweight (5) and the winding machine (4).

Conventional double deck elevators form an elevator car (1) by connecting an upper car (2) and a lower car (3) vertically, without increasing the area occupied by the hoistway in the building. Transportation capacity is increasing.

In such conventional double-decker elevators, in principle, a car located after a hall call in the direction of travel is assigned. Further, if there is a car that can simultaneously stop the call in the car in response to a hall call, that car is allocated.

However, with this type of double-decker elevator, even though the car you are riding in does not call, there are times when the elevator is waiting to stop at an intermediate floor for passengers in the other car to get on or off. Therefore, passengers in the car waiting for the car to stop may become psychologically irritated. Furthermore, even if a car is called in the car in which you are riding, if it takes time for passengers in the other car to get on and off, you will still be waiting for a long time to stop, and the passengers in the car may feel anxious. I feel irritated.

Therefore, in such a case, the conventional double deck elevator described in the above-mentioned Japanese Utility Model Publication No. 51-12825 displays the reason for non-departure to alleviate the anxiety and irritation of the passengers.

[Problems to be Solved by the Invention] However, in the conventional multi-deck elevator as described above, from the viewpoint of operation efficiency, in response to a hall call for the elevator car (1), as a general rule, the car located at the rear in the direction of travel is had been assigned. Therefore, there is a high possibility that there are passengers in the car waiting to stop, and the reason for not departing is simply displayed to the passengers in this car.
This did not significantly reduce passengers' feelings of anxiety and irritation.

Additionally, in order to reduce this type of frustration, measures have been taken to open the elevator doors of cars that are waiting to stop at intermediate floors to alleviate the feeling of being in a closed room. but,
Once an elevator door is opened, the elevator cannot run until the elevator door is closed, which reduces the efficiency of elevator operation.

Therefore, this invention reduces the number of passengers in the car waiting to stop at an intermediate floor when an elevator car is called for a landing, and can allocate multiple cars so that passengers do not feel anxious or irritated as much as possible. The objective is to provide a deck elevator.

[Means for Solving the Problems] The multi-deck elevator according to the present invention responds to a landing call of an elevator car formed by connecting a plurality of cars in the vertical direction by determining the possibility that there are passengers among the plurality of cars. a first car allocating means that allocates a car with a high probability of having a passenger; a second car allocating means for allocating a car with a high possibility of no passengers when passengers in the car can get off by stopping at a landing corresponding to a hall call; The present invention further includes a third car allocating means for allocating a car with a larger number of passengers when the probability of having passengers among the plurality of cars is approximately the same.

[Operation] In the present invention, in response to a hall call for an elevator car formed by connecting a plurality of cars in a downward direction, the possibility that there are passengers among the plurality of cars is determined by the first car allocation means. allocating a car with a high number of passengers, and using the second car allocating means, even if there is a passenger in any one of the plurality of cars, a car that is likely to have no passengers is stopped at the landing corresponding to the landing call. Accordingly, when a passenger in the car can get off, a car with a high probability of having no passengers is allocated, and furthermore, when the possibility of having a passenger among a plurality of cars is approximately the same, the third car allocation means: Since the car with the largest number of passengers is allocated, the car with the largest number of passengers is allocated to the hall call, and the number of passengers in the car waiting to stop at an intermediate floor can be reduced.

[Example] A double deck elevator will be described below as an example of the present invention.

FIG. 1 is a schematic diagram showing the overall construction of a double deck elevator according to an embodiment of the present invention.

When an elevator user operates 2FDB) to (IOFDB), the hall call registration for the elevator car (1) is stored in the RAM (10) via the communication control interface (11-). In response to the hall call for the elevator car (1), the control device (7) controls the elevator car (2) or the lower car (3) according to a predetermined program.
and, in accordance with this decision, Volume 1 aircraft (4)
By controlling the drive of the car, either the car (2) or the lower car (3) is assigned to - as appropriate.

In addition, in this double deck elevator, the status signals of the elevator car (1) are also transmitted via the communication control interface (
1, 1) to the control device (7). Therefore, the destination floor signal (
Various information such as the car number (car call) and car weight are also manually input to the control device (7).

Next, a program for allocating an upper car (2) or a lower car (3) to a hall call of the elevator car (1), which is executed by the control device (7) in item 1, will be explained.

FIG. 2 is a flowchart 1 showing an example of a control program for a double cylinder elevator, which is an embodiment of the present invention. In addition, in this example, the elevator car (1) is traveling upward in front of the 5th floor landing (5F) corresponding to the upper car (2).
In contrast, the case where the up button (5FUB) on the fifth floor landing (5F) is operated will be described. In addition, the elevator car (
It is assumed that there are two passengers in the lower car (3) in 1), and the destination buttons on the 8th and 9th floors are being operated.

First, in step S1, various information regarding the elevator car (1) (current position, running speed, direction of operation, load in the car, operation status of destination buttons in the car, etc.), and information on each landing (IF) are collected.
Various information related to the car call (IOF) (operation status of the second up button and down button of each landing, etc.) is stored in the RAM (10) via the communication control interface (11). In step S2, press the up button (5F) on the 5th floor landing (5F).
It is determined whether or not a hall call has been registered by operating UB). In this example, the fifth floor landing (5F)
Since the up button (5FUB) has been operated, it is determined that the hall call registration has been pressed, and the process advances to step S3. In step S3, it is determined whether the elevator car (1) is in operation and can respond to the hall call registration in step S2.

If the elevator car (1) is in operation and can respond to hall call registration, it is determined in step S4 whether the traveling direction of the elevator car (1) is an upward direction. If the running direction of elevator car (1) is -1-up direction,
In step S5, the elevator car (1
) is where the upper car (2) is passing by. In this example, the elevator car (1) is traveling up in front of the 5th floor (5F), and the 5th floor landing (
Since the elevator car (1) on the 5th floor is running at a speed that can respond to the call, steps S3 and S
4. In both steps, the determination is "YES", and the process proceeds to step S6. In step S6, the fifth floor landing (
An operation for allocating an elevator car (1) is performed in response to a hall call from 5F), and the elevator car (1) is stopped in accordance with the allocation. In addition, if it is determined "NO" in each of the determinations from step S2 to step S5, the process returns to the main routine consisting of a normal operation control program.

FIG. 3 is a flowchart 1 showing details of the routine of step S6 of the control program of FIG.

In the figure, in step S11, it is determined whether or not the 5th floor car call has been made by operating the destination button in the upper car (2); If the lower basket (
By operating the destination button in 3), it is determined whether or not a car call for the fourth floor is being made. In step Sll -1- basket (
If the 5th floor car call is made by operating the destination button in 2), and if the 4th floor car call is made by operating the destination button in the lower car (3) in step S12, either In this case, proceed to step 81.6 and go to the 5th floor landing (5F).
In response to the hall call registration by operating the up button (5FUB), car (2) is assigned to -, and in step 51-7, car (2) of elevator car (1) is assigned to the 5th floor landing (5F) according to the assignment. ) to stop. That is, step S]
, 1 in 1-car (2)] If the 5th floor car is called by operating the destination button in 2, there is a passenger in -1-car (2) who will get off at the 5th floor landing (5F). This is a highly likely case, and as a result, it is a case where the hall call registration is consistent with the operation of the up button (5FUB) on the fifth floor hall (5F).

In addition, if the fourth floor car call is made by operating the destination button in the lower car (3) in step 81.2, the lower car (
3), there is a high possibility that there are passengers getting off at the 4th floor landing (4F), and in this case, the lower car (3) stops at the 4th floor landing (4F), and as a result, the upper car (
This is a case where 2) matches the hall call registration by operating the "-Go up button (5FUB)" on the fifth floor (5F). However, in this embodiment, the lower car (
Since only the destination buttons for the 8th and 9th floors have been operated in step 3), "No" is determined in both steps Sll and step 812, and the process proceeds to steps S] and 3. In step 313, it is determined whether or not a car call has been made by operating the destination button in car 2 (2). Upper basket (
If no car call is made by operating the destination button in car 2), it is extremely unlikely that there are passengers in car 7 (2), and in this case, the process advances to step S18.
Allocate the lower car (3) to the landing call registration by operating the up button (5FUB) on the 5th floor landing (5F), and proceed to step S.
], elevator car (1) according to said assignment at 9
The lower car (3) is stopped at the 5th floor landing (5F). In this embodiment, since there is no passenger in the upper car (2), a car call should not have been made by operating the destination button in the upper car (2), so the process goes from step S18 to step S19. move on. In addition, in this program, if there are no passengers in the second car (2), the lower car (3) is assigned to the elevator car (1-) landing call (in the ascending direction). . This is because if the conditions for the car (2) and the lower car (3) are the same, it is more efficient to assign the lower car (3) to -. Therefore, if there are no passengers in the car (2), the lower car will respond to the landing call (in the ascending direction) of the elevator car (1) without considering the condition in the lower car (3). (3) is assigned. If the car is called by operating the destination button in the upper car (2) in step 813, then the car is called by operating the destination button in the lower car (3) in step 51-4. It is determined whether the Lower basket (3
) If no car calls have been made by operating the destination button in ), it is extremely unlikely that there are passengers in the lower car (3), and it is extremely unlikely that there are passengers in the second car (2). In this case, the process proceeds to step S16, and in response to the hall call for the 5th floor (5F), 1-car (2)
is assigned, and in step S17, the upper car (2) is stopped at the fifth floor landing (5F) according to the assignment. Step 81

3) If both cars are called by operating the destination button in 1-car (2) and lower car (3), there is a possibility that there are passengers in 1-car (2) and lower car (3). 3) are also considered to be substantially the same, so in this case, the number of passengers in the seventh car (2) is determined by comparing the load of the upper car (2) and the load of the lower car (3) in step S15. The number of passengers in the lower car (3) is compared. In other words, it is determined whether the load on the upper car (2) is greater than the load on the lower car (3).
) is larger than the number of passengers in the lower car (3), and in this case, the process proceeds to step S19 via steps S] and 8. Conversely, if the load on the -1-car (2) is small, the number of passengers in the upper car (2) is smaller than the number of passengers in the lower car (3), and in this case, The process advances to step S17 via step 816. In addition, in the double deck elevator of this embodiment, according to the flowchart 1 shown in FIGS. 2 and 3 above, the process returns to the beginning again at an appropriate calculation cycle (approximately 100 m5ec), and the above series of programs is repeated. executed.

Note that the second step described in step S17 and step s19
The elevator car (1
) is performed by the control device (7) appropriately controlling the drive of the winding machine (4).

'', the double deck elevator of this embodiment includes an elevator car (1) formed by vertically connecting a -t-x car (2) and a lower car (3), and the elevator car (
In response to the hall call (by operating the up button on the 5th floor landing) in 1), the first car assignment is to allocate the car that is most likely to have a passenger among the upper car (2) and lower car (3). means(

Then, in response to the hall call for the elevator car (1), the first car assignment means assigns the elevator car (2) and the lower car (3).
), the cars with a high probability of having passengers are assigned to the relevant landing area. Furthermore, by the second car assignment means, even if there is a passenger in one of the -1-car (2) and the lower car (3), the car that is most likely to have no passengers will respond to the hall call. When passengers in the car can get off by stopping at a landing, a car with a high probability of having no passengers is assigned. Furthermore, by the third car allocation means, -1-car (
2) and the lower car (3), when the probability of having passengers is approximately the same, the car with the largest number of passengers is assigned to the relevant landing.

Therefore, in this embodiment, a car with a large number of passengers is usually allocated more calls than a car with a small number of passengers in response to a hall call for elevator car (1). The number of passengers onboard can be reduced.

As a result, unlike conventional double-decker elevators, there is a reduction in the number of people waiting to stop at an intermediate floor for passengers in the other car to get on or off, even though the car they are riding is not called. As a result, the psychological irritation of passengers on board is reduced, and the chances of them feeling anxious or irritated are reduced. However, since there is no need to open the elevator door of a car waiting to stop at an intermediate floor to alleviate the feeling of being in a closed room, the operating efficiency of the elevator does not deteriorate.

As a result, a double deck elevator is created that does not make passengers in the car feel anxious or irritated as much as possible.

By the way, in the above embodiment, a double deck elevator in which a -1 car (2) and a lower car (3) are connected vertically is explained as an example of a multiple deck elevator.
The present invention can be similarly applied to an l-ripple deck elevator in which two cars are connected in the vertical direction, or even to a multiple deck elevator in which the number of cars is increased. However, if the number of cars is increased, the above 2.
The judgment operation in flowchart 1 shown in FIGS. 0 and 3 also increases, and the control program becomes complicated.

In addition, in the above embodiment, one elevator is
I explained what to do with multiple deck elevators,
It is also possible to apply the present invention to a multi-deck elevator in which a plurality of elevators manage a group of elevators (1,). In the case of a multi-deck elevator in which multiple elevators manage cars (1,) as a group, cars may be assigned to each elevator as described in -1-, or each car may be assigned a car as explained above. An assignment may be made.

Furthermore, as another application example, an evaluation formula may be created to obtain an evaluation value for each car, and the optimum car may be assigned.

[Effects of the Invention] As described above, the multi-deck elevator of the present invention has a first method of allocating a car to a landing call of an elevator car formed by connecting a plurality of cars in a downward direction. It is equipped with a car allocation means, a second car allocation means, and a third car allocation means, and the first car allocation means selects a plurality of cars that are likely to contain passengers to the relevant landing area. According to the second car allocation means, even if there is a passenger in any one of the plurality of cars, a car that is likely to have no passengers is allocated to the car by stopping at the landing corresponding to the landing call. When a passenger can get off the car, a car with a high probability of having no passengers is assigned, and further, when the probability of having a passenger is almost the same among the plurality of cars, the car with a large number of passengers is assigned. Since the car is assigned to the corresponding landing, it is possible to reduce the number of passengers in the car waiting to stop at an intermediate floor, and the psychological irritation of the passengers in the car is also reduced, reducing feelings of anxiety and impatience. The chances of feeling that way are greatly reduced.
