JP7036072B2 - Operation control method for multicar elevator system - Google Patents

Description

The present invention relates to an operation control method for a multi-car elevator system in which a plurality of baskets are used on one shaft, and more specifically, an operation of a multi-car elevator system in which a plurality of baskets are used on a plurality of shafts. It is about the control method.

In order to increase the operating rate with respect to the installation area of an elevator in a high-rise building or the like, a so-called multicar elevator system in which a plurality of baskets are independently used on one shaft has been proposed (see, for example, Patent Document 1).
In this type of multicar elevator, in addition to the service floor where passengers can get on and off, the lower side is below or above the service floor (generally the lower side, and the example provided below is described below). There is a garage floor where you can evacuate your basket (called the lower basket). As a result, both the upper basket (referred to as the upper basket) and the lower basket can be stopped on the lowest floor, which is the lowest service floor.
However, on the top floor, which is the uppermost service floor, the upper basket can be stopped, but the lower basket cannot be stopped due to the presence of the upper basket. In other words, the upper basket can be stopped on all service floors, and the lower basket can be stopped on service floors other than the top floor.

For this reason, passengers who wish to move to the top floor cannot be placed in the lower basket.

Therefore, in Patent Document 1, by displaying and guiding the serviceable service floor of the arrived basket, it is possible to determine whether or not one can reach the desired destination floor by getting in the basket. , When a basket that cannot be serviced arrives, the message "Please do not board" is displayed.

Japanese Patent No. 4194981

However, in the conventional method, there are an "immediate allocation method" that determines the basket that responds instantly when the destination floor is registered at the landing, and an "immediate forecast method" that immediately guides the shaft that raises and lowers the assigned basket at the landing. It is adopted.
That is, it is assumed that the passenger is waiting in front of the shaft for raising and lowering the assigned basket, and when the basket in the desired direction arrives, the passenger can reach the destination floor by getting on the basket.

An object of the present invention is to reach a desired destination floor by waiting for passengers to arrive at a designated shaft and boarding according to a vertical boarding guide in a multicar elevator system adopting an immediate allocation method and an immediate forecast method. It is to provide an operation control method of a multi-car elevator system that can be performed.

In order to solve the above problems, the operation control method of the multicar elevator system of the present invention is used.
This is an operation control method for a multi-car elevator system in which multiple baskets are deployed on multiple shafts so that they can be raised and lowered, and boarding guidance is provided by the immediate allocation method and the immediate forecast method.
For the combination of each floor and each direction, there is at least one basket that can be transported to all destination floors in that direction from that floor as the departure floor, and the basket that can be used in one direction is available. , Control is performed so that the car can arrive earlier than the other car in the shaft to which the car belongs and cannot handle one side, and the boarding guidance can be provided.

More preferably, a first-come-first-served determination means for determining which basket arrives first in each direction of each floor, at least based on the position and direction of the basket in the shaft.
A boarding / alighting determination means for determining whether or not to stop in each direction of each floor to provide boarding guidance for each basket based on the position and direction of the basket in the shaft.
With
If there is a different non-single-compatible basket in the shaft to which the single-sideable basket belongs,
It is determined by the first-come-first-served means that the basket that can handle one side arrives earlier than the different baskets that cannot handle one side.
Or,
Even if a different basket that cannot handle one side arrives first, it is determined that the car is stopped by the boarding / alighting determination means and the boarding guidance is not performed.
It is controlled so that there is at least one shaft satisfying the above.

According to the operation control method of the multicar elevator system of the present invention, if a serviceable basket cannot arrive first for all floors in the same direction, the service is provided by the basket. By preventing the car from moving up and down when the other car on the shaft to which the car belongs cannot be serviced, it is possible to prevent passengers from erroneously boarding. As a result, passengers can ride in the direction of the basket in front of the designated shaft without being aware of the same feeling as when riding in a single car elevator, that is, the upper and lower baskets.

Hereinafter, the multicar elevator system 10 of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of a multicar elevator system 10 to which the present invention can be applied.
As shown in FIG. 1, the multicar elevator system 10 has a plurality of baskets 30, 32 (α1, α0, β1, β0, γ1 and γ0) on a plurality of shafts 20 (α, β and γ) installed in a building, respectively. ) Is commissioned. In the illustrated embodiment, the number of shafts 20 is three, and two upper baskets 30 and two lower baskets 32 are provided on each of the shafts 20, but the number of shafts 20 is not limited to this. , The number of baskets 30 and 32 may be plural.

The building has a plurality of service floors 40 on which passengers can get on and off the baskets 30 and 32. Of the service floors, the service floor 40 located at the top is referred to as the top floor 42, and the service floor 40 located at the bottom is referred to as the bottom floor 44.

The shaft 20 is provided with a garage floor 46 on which the lower basket 32 can be retracted below the lowest floor 44. The garage floor 46 may be provided above the top floor 42, and in this case, the upper and lower parts of the following embodiment may be read as top and bottom.

A landing device 50, which will be described later, is deployed on each service floor 40. Passengers operate the landing device 50 to specify a destination floor, and a desired destination direction to arrive at the shaft 20 notified by the landing device 50. You can move to the destination floor by getting on the basket 30 or 32.

FIG. 2 is a control block diagram of the multicar elevator system 10 of the present invention.
The control of the multicar elevator system 10 is provided for each of the landing device 50 deployed on each service floor 40, the group management control means 60 for comprehensively controlling the baskets 30 and 32 of each shaft 20, and the shaft 20. The in-shaft operation control means 70 that controls the operation of the baskets 30 and 32 by an algorithm that causes a plurality of baskets 30 and 32 that are in service of the shaft 20 to move and respond to calls, and the individual baskets 30 and 32 are operated in the shaft. This is performed by the basket control means 72 that travels, opens and closes the door, and the like according to the instructions of the operation control means 70.

More specifically, as shown in FIG. 3, the landing device 50 is arranged on each service floor where passengers can get on and off, and the landing call registration means 52 in which passengers specify the destination floor and passengers who specify the destination floor. It is provided with an arrival forecasting means 54 that displays the location of the shaft 20 to which the basket 30 or 32 to be boarded is assigned, and a boarding guidance means 56 that guides the ascending / descending direction of the basket 30 or 32 arriving at the shaft 20. ..

The landing call registration means 52 registers the destination floor desired by the passenger, and the information on the landing call registered in the landing call registration means 52 is sent to the group management control means 60.
The arrival forecasting means 54 is a means for notifying passengers of the shaft 20 assigned to the generated landing call and instructing the passengers to wait on the notified shaft 20.
The boarding guidance means 56 is a means for indicating the ascending / descending direction of the basket 30 or 32 arriving by the shaft 20 notified by the arrival forecasting means 54, and is upward when the destination floor is upward and downward when the destination floor is downward. Notify. For example, the boarding guidance means 56 may be a triangular hole lantern indicating an upward direction or a downward direction.

The arrival forecasting means 54 and the boarding guidance means 56 also operate based on the information from the group management control means 60.

By registering the desired destination floor in the landing call registration means 52, the user waits in front of the shaft 20 notified by the arrival forecast means 54, and follows the guidance of the boarding guide means 56 in the desired direction of travel ( When the basket 30 or 32 in the destination direction) arrives, the passenger may get on the basket 30 or 32.

As described above, the group management control means 60 is a device that comprehensively controls the operation of the baskets 30 and 32 of each shaft 20, and more specifically, the allocation candidate selection means 62, the optimum allocation determination means 64, and the group management control means 60. It is equipped with first-come-first-served determination means 66 and boarding / alighting determination means 68.

The allocation candidate selection means 62 excludes the unassignable shaft 20 from all the shafts 20 so that any of the baskets 30 or 32 can be assigned immediately whenever a call to the top floor occurs. , Is a means of selecting a candidate shaft 20.
The optimum allocation determination means 64 is a means for allocating a call to the shaft 20 so that the waiting time, the boarding time, and the like are optimized from among the shafts 20 selected by the allocation candidate selection means 62.

Further, in the first-come-first-served determination means 66, which basket is from the other basket in each direction of each floor based on the position and direction of each basket 30 and 32 in the shaft 20 and the call assigned to the baskets 30 and 32. Is also a means of determining whether it can arrive first.

The boarding / alighting determination means 68 is stopped in a direction on a certain floor based on the positions and directions of the baskets 30 and 32 in the shaft 20 and the calls assigned to the baskets 30 and 32, and is by the boarding guidance means 56. It is a means for determining whether or not the vehicle is in a state of providing boarding guidance.

Here, selective collective operation (hereinafter referred to as “selector operation”), which is a conventional operation method, will be described.
The terms used in this specification are defined as follows.
-[Front call]: As shown in Q1 and Q2 in FIG. 4, the basket is called in the same direction as the moving direction (destination direction) of the basket, and the position of the basket is the same as the departure floor or the traveling direction side. It is a call on the (destination direction side).
-[Face-to-face call]: As shown in Q3 and Q4 in FIG. 4, the movement direction of the basket is opposite to the traveling direction (destination direction), and in order to respond to the call, the basket is moved beyond the current floor. It is a call that needs to be moved to and flipped.
-[Sakazura call]: As shown in Q5 and Q6 in FIG. 4, the movement direction of the basket is opposite to the traveling direction (destination direction), and the position of the basket is the same as the departure floor or the traveling direction. It is a call on the opposite side (opposite to the destination direction).
-[Back call]: As shown in Q7 to Q9 in FIG. 4, the basket moves in the same direction as the traveling direction (destination direction), and the position of the basket is on the opposite side of the traveling direction from the departure floor (rear call). It is a call on the opposite side of the destination direction).
-[Available] (For example, "Cago C can respond to Call Q"): Only Call Q allows C to get passengers on the departure floor and get off at the destination floor.
-[Single-sided support] (For example, "Cago C can handle single-way support at departure floor F and direction D"): Basket C can handle all calls in direction D at departure floor F. ..
-[Passing] (for example, "Cago C passes through the floor F in the direction D"): The basket C passes through the floor F in the direction D, or stops at the floor F and then in the direction D. To move.
-[Getting on and off] (for example, "the basket C gets on and off the floor F in the direction D"): The passenger guidance means 56 calls one of the destination floors where the basket C stops at the floor F and the direction is D. To guide passengers to board the vehicle according to the boarding guide, or to disembark the call where the basket C passes to the floor F in the direction D and the destination floor is F. When getting on and off, since the guidance method (boarding guidance) is based on the direction, the non-discrimination constraint R3 must be obeyed regardless of the destination floor. Therefore, all the calls whose departure floor assigned to a certain shaft is the floor F and the direction is D will be boarded.
-[Preceding] (for example, "Cago I leads the floor F in the direction D ahead of the basket J"): It means that the basket I passes through the floor F in the direction D before the basket J. Which basket precedes depends on the operation method in the shaft.

As shown in Fig. 5, [front call] is the first quadrant, [face-to-face call] is the second quadrant, [reverse call] is the third quadrant, and [rear call] is the fourth quadrant. Occasionally, the service is in a small quadrant, i.e., the counterclockwise quadrant indicated by the arrow L in the figure. That is, in the selecole operation, a call that can respond in ascending order of quadrant is searched from among the multiple baskets assigned to the basket, and if the smallest quadrant of the held call is the first quadrant or the third quadrant, the player goes out. Is the call of the nearest floor, and if it is in the 2nd or 4th quadrant, the basket is moved to the call of the farthest floor, the door is opened and closed, and boarding / alighting guidance is given.
As can be seen by referring to the arrows L1 and L2 in FIG. 5, in the first quadrant and the third quadrant, and in the second quadrant and the fourth quadrant, when the moving direction of the basket is opposite, the first quadrant becomes the third quadrant. , The second quadrant is the fourth quadrant.

The state transition diagram of the selection operation is shown in FIG. 6, and the flowchart is shown in FIGS. 7 to 9.
The operation when the current mode is <idle> is performed as follows (see FIGS. 6 and 7).
-At the time of import = no current direction (step S101 in FIG. 7).
-Transition condition (step S102) and processing =
When the condition G101 is satisfied: The mode is changed to <rise> (step S103).
When the condition G102 is satisfied: The mode is changed to <descending> (step S104).
-Processing (when none of the transition conditions are satisfied) = Nothing is performed, and the process waits until the conditions change or an appropriate time elapses (step S105).

The condition G101 (step S103) is satisfied when any of the following is satisfied.
・ The departure floor is the current floor of the basket and there is an upward call.
・ There is a landing call above the current floor of the basket.
・ There is a basket call with the destination floor above the current floor of the basket.

The condition G102 (step S104) is satisfied when any of the following is satisfied.
・ The departure floor is the current floor of the basket and there is a downward call.
・ There is a landing call below the current floor of the basket.
・ There is a basket call with the destination floor below the current floor of the basket.

The operation when the current mode is <rise> is performed as follows (see FIGS. 6 and 8).
-At the time of import = the current direction is on the top (step S111 in FIG. 8).
-Transition condition (step S112) and processing =
When the condition G103 is satisfied: The mode is changed to <descending> (step S113).
When the condition G104 is satisfied: The mode is changed to <idle> (step S114).
-Processing (when none of the transition conditions are satisfied) = [front call] and [face-to-face call] are serviced (step S115).

The condition G103 (step S113) is satisfied when all of the following are satisfied at the same time.
-Neither basket call, [front call], nor [face-to-face call] is assigned.
-Either [reverse call] or [back call] is assigned.

The condition G104 (step S114) is satisfied when there is no call of any kind in the basket.

The operation when the current mode is <downward> is performed as follows (see FIGS. 6 and 9).
-At the time of import = the current direction is down (step S121 in FIG. 9).
-Transition condition (step S122) and processing =
When the condition G103 is satisfied: The mode is changed to <rise> (step S123).
When the condition G104 is satisfied: The mode is changed to <idle> (step S124).
-Processing (when none of the transition conditions are satisfied) = [front call] and [face-to-face call] are serviced (step S125).

Based on the above, the operation of the elevator, which is a general operation of the elevator, has been described using a state transition diagram and a flowchart. Subsequent operation of the basket will be explained using a state transition diagram, omitting the flowchart.

In a multicar elevator, multiple baskets run in the shaft. However, the operation method is not free, and collisions between cars in the shaft must be avoided.
This means that one basket will prioritize the other in order to resolve the interference, and depending on how it is prioritized, a particular basket may not be able to serve indefinitely. Therefore, the conditions implicitly guaranteed by an elevator with one basket in the shaft are not always satisfied by the multicar elevator, and it is necessary to consider the following constraints.

-Immediate allocation constraint (R1): A constraint that determines which shaft the basket belongs to when a landing call occurs. This is a restriction for the user to know which shaft should wait for the arrival of the basket when the landing call is registered in the landing call registration means 52.

-Assignment non-changeable constraint (R2): A constraint in which the shaft to be assigned to the generated landing call is once determined and then the shaft is not changed. When the shaft allocation is changed, it is necessary to guide the user to move the waiting shaft, and this is a restriction provided to avoid the troublesomeness of the user. Note that this restriction allows changes to the cage inside the shaft.

-Non-sorting constraint (R3): This is a constraint caused by having multiple response baskets in the shaft for one boarding guidance means 56 (guidance only up and down), and is currently arriving at a certain destination floor. It is not possible to get on a basket that arrives after the next one instead of the one that is there. Therefore, when all the baskets C [get on and off] in the direction D from the floor F, regardless of the shaft, it is necessary to respond to all the calls satisfying the following conditions.
Condition: Basket call occurrence condition: Departure floor is F and direction is D. Landing call

-Fairness constraint (R4): A constraint that must always respond to the registered landing call Q. That is, it is a restriction for preventing a state in which the basket C cannot respond to the call Q permanently by setting the number of times the basket C is inverted or passed without responding to the landing call Q to a predetermined number or less.

-Non-passable constraint (R5): If a landing call Q (with multiple) whose direction is D on the departure floor F is assigned to the shaft, the basket that moves to the floor F and then moves to the direction D is , A constraint that must be answered for all of those landing calls Q.

-Reversal constraint (R6): All baskets C are constraints that move or [get on and off] in order to respond to [front call] or [face-to-face call] as long as there is a basket call beyond the current floor. In the present invention, as will be described later, the basket cannot be passed because the impassability constraint (R2) is provided, but if the impassability constraint (R2) is not provided, only the landing call is made. It may be passed without making a response.

With respect to the above constraints (R1) to (R6), the immediate allocation constraint (R1), the non-assignable constraint (R2), and the non-separation constraint (R3) are always applied in the present specification.

In the multicar elevator system in the present specification, as shown in FIG. 10, the boarding guidance means 56 is only up and down, and it is determined whether the basket in the shafts α, β, and γ is the upper basket or the lower basket. Can not do it. Therefore, it is necessary to prevent the user from accidentally getting in the basket that cannot move to the destination floor in the shaft. Therefore, the first-come-first-served determination means 66 and the boarding / alighting determination means 68 perform operation control so that at least one shaft that always satisfies any of the following conditions exists for all floors F and all directions D. ..
-In the shaft, a basket that is [single-sided] is [leading] in the floor F and direction D.
・ For all the baskets in the shaft, if you [lead] from any of the baskets that are [single-sided] to the floor F and direction D, do not [get on and off] (pass) on the floor F and direction D. Can be done). In other words, any basket that is not [single-sided] will not [get on and off] until any of the baskets that are [single-sided] pass through.
However, it is not necessary for all shafts to comply with this operation control, as long as there is room for immediate allocation and response regardless of which floor the call occurs, and at least one shaft for each floor and each direction. However, if the floor and direction are different, other shafts may follow this operation control.

The allocation candidate selection means 62 described above narrows down the shafts that can be serviced when a call occurs according to the procedure of FIGS. 11 to 13, and allocates the optimum shaft.

As shown in FIG. 11, in the call assignment procedure, N is the call to be assigned (step S201).
A is used as an allocation candidate set for all shafts, and for each shaft H, first, every time a call N is generated, it is determined whether or not a shaft that can be assigned to this call N can be assigned (loop steps S203 to Step S206).

Specifically, for each shaft H belonging to the allocation candidate set A, whether any basket in the shaft H can correspond to the call N, that is, the shaft H satisfying the following condition G404 is removed from the allocation candidate set A. (No in step S204 and step S205).

The condition G404 is satisfied when the following conditions are satisfied.
-Not all baskets in shaft H are [available] to call N.

By making the above determination for all the shafts, it is possible to exclude the shafts that cannot be serviced and leave only the shafts that can be serviced in the allocation candidate set A.

When the number of shafts belonging to the allocation candidate set A becomes one by the above determination, the allocation candidate selection means 62 allocates the shaft to the only candidate (Yes in step S207 and step S208).

On the other hand, when a plurality of shafts belonging to the allocation candidate set A remain (No in step S207), as shown in FIG. 12, the procedure for selecting from the plurality of shafts is executed, and candidates are selected from the allocation candidate set A. The shafts to be used are narrowed down (step S209), and the optimum allocation is performed from the narrowed down shafts (step S210).

To select the optimum shaft from the plurality of shafts, first, the first-come-first-served determination means 66 counts the number of shafts (Z401) satisfying the following condition G401 for the shafts belonging to the allocation candidate set A (FIG. 12). Step S301).

The condition G401 is satisfied when the following conditions are satisfied.
-On the shaft H, a basket that is [single-sided] is [leading] for all floors F and directions D.

That is, the basket of each shaft H belonging to the allocation candidate set A is [single-handed] for all calls in the direction D for all floors F, and the basket is in the same shaft. Determine if it is possible to [pass] before the basket of.

For each shaft, the condition G401 is determined, the number of shafts (Z401) is counted (step S302), and if the number is 1 or more, the process proceeds to the next step S303. If the above condition G401 is not satisfied, the process proceeds to step S304.

When the number of shafts (Z401) satisfying the condition G401 is 1 or more (Yes in step S302), and when the number is 1 or more, the corresponding shaft is set as the current candidate of the allocation candidate set A (step S303). ).

When the number of shafts (Z401) satisfying the condition G401 is zero (No in step S302), the nominal N is tentatively assigned to the shaft H for the allocation candidate set A (loop step S304 to step S308), and the next condition G405 Is applied to narrow down the shaft (step S306 and step S307).

The condition G405 is satisfied when all of the following are satisfied at the same time.
-For all combinations of floors F and directions D, there is no shaft that satisfies the following condition G406 or condition G407. That is, not all shafts satisfy both the condition G406 and the condition G407.

The condition G406 is satisfied when the following conditions are satisfied.
-A basket that is [single-sided] with the floor F in direction D "leads" to any basket in the shaft.

The condition G407 is satisfied when the following conditions are satisfied.
-For all the baskets that [lead] to the baskets that are [single-sided] in the direction D of the floor F, pass through the floor F without [getting on and off] (see Fig. 13 and the following) in the direction D. Can be done.

The determination of getting on and off follows the procedure for determining getting on and off as shown in FIG. In other words, the determination of getting on and off is the determination of whether the basket K of interest in the shaft can pass through the floor F of interest in the direction D of interest, or whether it is necessary to stop for passengers to get on and off. Is. This determination can be performed by the boarding / alighting determination means 68.

First, the focus basket is K, the focus floor is F, and the focus direction is V (step S401).
At this time, it is determined whether or not the basket K gets off on the floor F based on whether or not all of the following conditions are satisfied (step S402).

Conditions ・ The basket K has a call with the floor F as the destination floor.
・ A call is made to the basket K with the destination floor beyond the floor F.

When all the above conditions are satisfied (Yes in step S402), the basket K stops at the floor F, and after the stop, has a stop floor in the same direction beyond the floor F. In this case, since the basket K cannot pass through the floor F and needs to be stopped for getting off, the process proceeds to step S405 and the boarding / alighting determination "true" is returned.

If any or all of the above conditions are not satisfied (No in step S402), it is determined whether or not the basket K gets on the floor F based on whether or not the following conditions are satisfied (step S403).

Conditions ・ There is a call that responds without passing through when the departure floor is F and the direction is V.

If the above conditions are satisfied, the basket K cannot pass through the floor F because the basket K stops at the floor F and responds to the call to board the passenger (Yes in step S403). Therefore, the process proceeds to step S405, and the boarding / alighting determination "true" is returned.

When the condition of step S403 is not satisfied (No of step S403), it is determined whether or not there is at least one nominal R that satisfies all of the following conditions (step S404).

Condition ・ The destination floor of the call R is F.
-The direction of the nominal R is V.
・ Get on and off at the departure floor org (R) of the call R.

In this case, the focus basket K, the focus floor is org (R), the focus direction is V, and the boarding / alighting determination is performed recursively, and if these conditions are satisfied, the boarding / alighting determination "true" is returned ( Yes in step S404 and step S405).

If there is no call R that satisfies the condition of step S404, the boarding / alighting determination "false" is returned (No in step S404, step S406).

According to the above flowchart 13, it is possible to determine the boarding / alighting of a plurality of (Z401) shafts remaining in the allocation candidate set A, and when the boarding / alighting determination is “true”, the condition G407 “cannot pass”, that is, the condition. It is determined that G407 is not satisfied, and if the boarding / alighting determination is "false", the condition G407 is "passable", that is, it is determined that the condition G407 is satisfied.

As a result, the shafts satisfying the above condition G405 are excluded (steps S306 and S307), and the remaining shafts that are not excluded are set as the allocation candidate set A, and the optimum allocation is determined from them (step S210 in FIG. 11).

[Priority time stamp]
In consideration of the fairness constraint (R4), in the present invention, the operation of each basket of each shaft is basically performed according to the operation of the selection.
However, unlike the case where there is only one basket on the shaft, since multiple baskets operate in the shaft, when the baskets move in the direction facing each other, that is, when the upper basket moves downward and the lower basket moves upward. , Mediation is required to avoid collisions.
Therefore, a time mark is provided between the baskets so that the interference between the baskets can be resolved based on the time mark.

The time stamp is issued as the time when the basket call is eliminated and the [reverse call] and [back call] are serviced for [front call] and [face-to-face call]. Priority is given to the time stamps of each basket, and the time stamps with priorities are designated as [priority time stamps].
As for the priority of the time stamps, the older the time stamp is, the higher the priority is, and if the time stamps are the same, the order of the basket numbers can be used.

In addition, when the basket gets the desired direction, that is, when the lower basket can be raised or the upper basket can be lowered, or when the call to the basket is no longer necessary due to the allocation change, the other basket is requested. If there is a direction in which you are doing, you can give way to the other basket, so the [Priority time mark] will be deleted.

According to the above, the operation of the upper basket can be controlled based on the [priority time mark].

More specifically, when the [preceding] when two upper and lower baskets are operated on one shaft, the basket I [preceding] the floor F from the basket J in the direction D is the operation method in this shaft. In, it shall be as follows.

Assuming that the departure floor is F and the direction is D and the call Q (which does not have to be actually registered) is set, "the basket I is the first quadrant with respect to the call Q, and the basket J is from the first quadrant. Is it larger, or even in the first quadrant, the basket I is closer to the floor F. " However, if neither is in the first quadrant, neither is [preceding].

The operation control in the shaft of the multicar elevator differs depending on whether or not the above-mentioned impassability constraint (R5) is applied in operation.
That is, it is necessary to distinguish between the case with the impassability constraint (R5) and the case without the impassability constraint (R5).

When there is a non-passable restriction (R5), it is necessary to wait so that the car that cannot respond to the movement or change of direction of the car does not [lead] as an operation policy. This is because, within the assigned shaft, if the next direction of movement is the same as the calling direction, it must respond without being able to pass through the departure floor where the calling is occurring.

The movement restriction of the basket, which becomes a problem when there is an impassability restriction (R5), will be described.
For example, as shown in FIGS. 24 and 25, two baskets α1 and α0, β1 and β0, and γ1 and γ0 are used in the three shafts α, β, and γ, respectively, and are located below the bottom floor. An example is a multicar elevator system provided with a garage floor where a basket can be retracted.

In the multi-elevator system having the above configuration, for example, the following problems occur (problem 1).
For example, as shown in FIG. 24, the baskets other than γ0 are moving upward, α1 is climbing the 8th floor, α0 is getting on and off the 1st floor, β1 is climbing the 9th floor, and β0 is the 1st floor. It is assumed that γ1 is climbing the 7th floor and γ0 is waiting on the garage floor without any direction while getting on and off.

In this case, the basket γ0 cannot turn upward. This is because when γ0 is also upward, only the lower basket [leads] in the upper direction on the first floor, and the call to the top floor where the lower basket cannot be moved is mistakenly boarded. Therefore, it is necessary to maintain the standby until α0 or β0 starts from the first floor.

In addition, the following problems also occur (Problem 2).
For example, as shown in FIG. 25, all the baskets are moving upward, α1 is climbing the 14th floor, α0 is getting on and off on the 8th floor and the basket is called on the 12th floor, and β1 is on the 15th floor. While climbing, β0 is getting on and off on the 7th floor and has a basket call on the 13th floor, γ1 is on the 5th floor before starting and has a basket call on the 10th floor, and γ0 is climbing on the 2nd floor and has a basket call on the 11th floor. do.

In this case, the start of the basket γ1 must be after either the basket α0 or β0 [passes] on the 9th floor and arrives at the 10th floor. This is because if the basket γ1 [passes] on the 10th floor earlier than that, the only basket that [leads] in the upward direction on the 9th floor will be the lower basket, and the lower basket will be erroneously called to the top floor where it cannot move. This is because it will cause them to do so.

In order to solve these problems 1 and 2, under the impassability constraint (R5), the start of the upper basket and the upward reversal of the lower basket are restricted. Alternatively, since the passage of the car is not allowed due to the impassability restriction (R5), it is conceivable that the car will be stopped without advancing the service until the situation changes due to the movement of the car of another shaft.

Therefore, regarding the operation of the upper basket shown in FIG. 19, the current position when moving is performed as a condition for servicing [front call] and [face-to-face call] in the execution processing of the modes <climb> and <reverse ascending>. The following conditions are added for each floor from to the floor immediately before the destination.

Condition: Regarding the floor F and the upward direction, there is one other shaft that can be [single-sided] in advance.

By adding this condition, when only the shaft is [single-sided] from the current position to the floor immediately before the destination, it operates so as not to start. As a result, it is possible to solve the problem 1 that all the shafts cannot respond to the call to the top floor.

For the lower basket, in addition to the condition G203 in FIG. 14, the following conditions are added. Condition: Condition G203 and even if the direction is up, there is one shaft that can be [single-sided] upward for each floor. exist.

When the above condition is not satisfied, the problem 2 can be solved by maintaining the standby in the mode <descending inversion required>.

As described above, the above problems 1 and 2 can be solved by adding the state transition condition to the operation algorithm when the impassability constraint (R5) is present.

Further, when there is no impassability restriction (R5), even if the next [passing] direction is the same as the landing call, when the car call is not answered, the car can be allowed to pass. For this reason, as an operation policy, it is necessary to control the allocation so as to avoid the situation where the unsupported basket [precedes] and gets on and off.

The operation under the condition that there is no impassability restriction (R5) can be the zone operation, that is, the operation based on the [zone boundary] and the [own zone call] described below.

-[Zone boundary]: The [Zone boundary] of the basket J is the range in which the basket J moves. For example, as shown in FIG. 26, when three upper baskets α2, an intermediate basket α1, and a lower basket α0 are operated on one shaft and two garage floors are provided on the lower side, the upper boundary of each basket is provided. Is referred to as [zone boundary]. More specifically, in the illustrated embodiment, the [zone boundary] of the middle basket α1 is on the 8th floor, and the [zone boundary] of the lower basket α0 is on the 4th floor.

-[Own zone call]: In the [Own zone call] of the basket J, both the departure floor and the destination floor of the call are below the [zone boundary] of the basket J, and either the departure floor or the destination floor of the call is It is called above the [zone boundary] of the basket one below the basket J. More specifically, the [own zone call] of the basket α1 is a call in which either the departure floor or the destination floor of the call is on the 5th to 8th floors.

Basically, in zone operation, if the [own zone call] of the basket is in [front call] or [face-to-face call], you can stop and get on and off, and if there is a basket call, you can get on and off. If not, it passes without answering [Call your zone].

Specifically, assuming that the [zone boundary] of the lower basket α0 shown in FIG. 27 is the 4th floor, the upper basket α1 passes through the 2nd floor and [gets on and off] on the 3rd floor. Due to non-discrimination restrictions (R3), calls from the 3rd floor to the 4th floor are also allowed to board.

If the basket's own zone call is not in [Front call] or [Back call], flip it from top to bottom. However, the upper basket must meet the conditions for the lower basket. Note that only the top to bottom are considered because the garage floor is on the lower side.

In the case of zone operation without the impassability restriction (R5), the following problems occur.

"Problem 3: Case where the chain of calls becomes a problem"
You can get on and off the call if you are in your own zone. However, even if there is [Call your own zone], you may have to avoid it by allocating if you cannot pass through.
That is, as shown in FIG. 28, the lower zone boundaries of the lower baskets α0, β0, and γ0 are on the 12th floor, the upper baskets are all outside the lower zone boundaries, the lower baskets α0 are on the 8th and 9th floors, and the lower basket β0 is 8th. It is assumed that a new landing call Q1 with the departure floor as the 7th floor and the arrival floor as the 8th floor occurs under the situation where the 7th and 10th floors are assigned to the lower baskets γ0 on the 10th floor and the 10th floor.
In this case, the new landing call Q1 cannot be assigned to the shaft γ. This is because, after assigning the new landing call Q1 to the lower basket γ0, when a new landing call with the top floor as the arrival floor occurs on the 8th floor, all the baskets that can respond become the lower basket, and the top floor. This is because the boarding call to the destination is mistakenly boarded.

"Problem 4: Case where call chain (multiple chains) becomes a problem"
Further, as shown in FIG. 29, the lower zone boundaries of the lower baskets α0, β0, and γ0 are on the 12th floor, and the upper baskets are all outside the lower zone boundaries. Consider the situation where the 5th and 10th floor basket calls are assigned to the 5th and 10th floors and the lower basket γ0.
If the 5th floor landing call Q1 assigned to the shaft γ is a landing call with the arrival floor as the 7th floor, it is assumed that a new landing call Q'with the departure floor as the 7th floor and the arrival floor as the 9th floor has occurred. .. At this time, this new landing call Q'cannot be assigned to the shaft γ. This is because, after assigning the new landing call Q'to the lower basket γ0, when a new landing call with the top floor as the arrival floor occurs on the 9th floor, all the baskets that can respond become the lower basket, and the top This is because the call to the floor is mistakenly boarded.

"Problem 5: Cases where forced passage is required"
As shown in FIG. 30, the lower zone boundaries of the lower baskets α0, β0, and γ0 are on the 12th floor, and the upper baskets are all outside the lower zone boundaries. Consider the case where the landing calls on the 9th and 10th floors and the lower basket γ0 are assigned to the 5th and 10th floors, and the landing call Q1 on the 5th floor assigned to the lower basket γ0 is the landing call with the arrival floor as the 7th floor. ..
It is assumed that a new landing call Q'with the departure floor as the 7th floor and the arrival floor as the 9th floor has occurred. At this time, the new landing call Q'may not be assigned to the shaft γ but may be assigned to the shaft β. However, it is necessary to pass the lower basket β0 on the 7th floor without getting on and off. This is because, after assigning the new landing call Q'to the lower basket β0, when a new landing call with the top floor as the arrival floor occurs on the 7th floor, all the baskets that can respond become the lower basket, and the top This is because the call to the floor is mistakenly boarded.

"Problem 6: Case where forced reversal is required"
As shown in FIG. 31, the lower zone boundary of the lower basket α0, β0, γ0 is on the 12th floor, and the upper baskets are all outside the lower zone boundary. Consider the situation where β0 is assigned the 9th and 10th floors, and the lower basket γ0 is assigned the 5th floor.
At this time, if the landing call Q1 on the 5th to 7th floors, the landing call Q2 on the 7th to 9th floors, and the landing call Q3 on the 9th to 11th floors are assigned to the shaft γ, the basket γ0 is the landing call Q1 and the landing. You can answer the call Q2.
However, it must be reversed without responding to the landing call Q3. This is because the only basket that gets on and off in the upward direction on the 9th floor is the lower basket, and if a new landing call with the top floor as the arrival floor occurs, an erroneous boarding will be induced.

In order to solve the above problems 1 to 3, in the zone operation algorithm when there is no impassability constraint (R5), the call is answered when the following conditions G601 and G602 are satisfied.

Condition G601: All responding calls are included in the own zone or the zone of the lower basket, and at least one is in the own zone.
Condition G602: Even if the basket responds to the target call, there is at least one shaft that can be immediately assigned regardless of which floor the call occurs.

The call to the top floor occurs on the target floor F by responding to the landing call only when all of the above conditions G601 to G602 are satisfied, that is, by not responding when any of the conditions is not satisfied. It is possible to prevent the induction of erroneous boarding due to.

Further, as a reversal condition in the zone operation algorithm when there is no impassability constraint (R5), in addition to the establishment of the conventional reversal condition, one of the following conditions is satisfied (however, the following conditions are two baskets). In the case of).

-Condition G611: There is no landing call in the second quadrant or less, and there is no basket call.
-Condition G612: Even if there is a landing call in the first quadrant, the response condition of the call is not satisfied.

"Problem 7: The case where the priority time mark is retained when the response condition is not satisfied"
Further, if the lower car transitions to the mode <descent required reversal> without satisfying any of the above-mentioned conditions G601 to G602, the situation continues to stand by without operating while holding the time mark that has priority over the upper car. There is a possibility of falling into. The above-mentioned conditions G202, G203 and G205 in FIG. 14 are changed to the conditions G222, G223 and G225, respectively, as shown in the following and the state transition diagram 32 and the flowcharts FIG. 33 and FIG. 34. In addition, since the parts other than the changed parts are the same as those in FIGS. 14 to 18, the same reference numerals are given and the illustrations and explanations are omitted as appropriate.

The condition G222 (step S703) is satisfied when all of the following conditions are satisfied (FIGS. 32 and 33).
・ There is no basket call, [front call], or [face-to-face call].
-Even if the direction is turned up, there is a [front call] or [face-to-face call] that satisfies the response condition.

-Satisfy the condition G222.
-The mode of the upper basket is raised, the [Priority time mark] is older than the upper basket, or the mode of the upper basket is idle.

The condition G225 (step S714) is satisfied when the following conditions are satisfied.
-Even if the direction is turned up, neither [front call] nor [face-to-face call] that satisfies the response condition exists.

Similarly, the transition condition G212 from the mode <rise> to the mode <reverse ascending> of the upper basket in FIG. 19, the transition condition G213 from the mode <reversal required to ascend> to the mode <reversal required>, and the mode <reversal required to ascend>. The transition condition G215 from> to the mode <rise> is also changed to the conditions G232, G233 and G235, respectively, as shown below and in the state transition diagrams 35, flowcharts 36 and 37. In addition, since the parts other than the changed parts are the same as those in FIGS. 19 to 23, the same reference numerals are given and the illustrations and explanations are omitted as appropriate.

The condition G232 (step S803) is satisfied when all of the following conditions are satisfied (FIGS. 35 and 36).
・ There is no basket call, [front call], or [face-to-face call].
-Even if the direction is turned down, there is a [front call] or [face-to-face call] that satisfies the response condition.

The condition G233 (step S813) is satisfied when all of the following conditions are satisfied (FIGS. 35 and 37).
-Satisfy the condition G232.
-The mode of the lower basket is down, the [Priority time mark] is older than the lower basket, or the mode of the lower basket is idle.

The condition G235 (step S814) is satisfied when the following conditions are satisfied (FIGS. 35 and 37).
-Even if the direction is turned down, neither [front call] nor [face-to-face call] that satisfies the response condition exists.

By changing the condition in this way and adding the establishment of either the above condition G611 or G612 to the inversion condition, the above problem 4 at the time of inversion can be solved.

Even if the number of baskets in the shaft is increased by performing the above operation control, passengers on any service floor can manage the group simply by operating the landing call registration means 52 and designating the destination floor. Since the shaft and the basket to be boarded are immediately assigned by the control means 60, the passenger gets on the arrived basket in front of the shaft designated by the arrival forecast means 54 based on the direction indication indicated by the boarding guide means 56. Then you can reach the desired destination floor.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.

For example, in the above embodiment, a multicar elevator system in which a plurality of baskets are commissioned for all shafts has been described, but it is sufficient that there is at least one serviceable basket, and in this case, a single car shaft is used. It may be mixed.
If there is one or more shafts in which all the baskets in the shaft can service the combination of the departure floor and the destination floor, the operation method of the present invention may not be used. For example, if there is a single car shaft that serves all floors.
