Description

An embodiment of the present invention relates to an elevator group management system that controls the operation of elevators (double-deck elevators) having cars that are vertically connected.

Elevators have an operation called "VIP (very important person) operation" in which specific users are prioritized over general users in the operation service. VIP operation is operation in which only a specific user is placed in a car and the car goes straight to the destination floor of the user. During VIP operation, allocation of normal hall calls is prohibited in order to avoid boarding of general users. On the other hand, in a skyscraper or the like, a double-deck elevator is used in which the cage is constructed in two stages, upper and lower, in order to improve the space efficiency of the building. When a VIP operation is applied to such a double-deck elevator, the elevator is operated with a specific user in the upper car or the lower car.

JP 2007-84242 A

When one car of the double-deck elevator carries a specific user and is in VIP operation, the other car is vacant because normal hall call allocation is prohibited. As a result, the transport capacity of the double-deck elevator cannot be exhibited, and the operating efficiency is significantly reduced.

The problem to be solved by the present invention is to efficiently operate a double-deck elevator with specific users in one car and general users in the other car without impairing the operation service for VIP calls. To provide an elevator group management system capable of

An elevator group management system according to one embodiment controls the operation of an elevator having two vertically connected cars. The elevator group management system includes first registration means, second registration means, first allocation control means, and second allocation control means. The first registration means registers a first destination call including a specific user's destination floor and departure floor at each floor's boarding hall. The second registration means registers a second destination call including destination floors and departure floors of general users at the landings of the respective floors. The first allocation control means allocates the first destination call registered by the first registration means to one car of the elevator. The second allocation control means compares the destination floor and departure floor of the second destination call registered by the second registration means with the destination floor and departure floor of the first destination call, If the second destination call does not affect the response to the first destination call, the other car of the elevator is assigned the second destination call.

Embodiments will be described below with reference to the drawings.
The disclosure is merely an example, and the invention is not limited by the contents described in the following embodiments. Modifications that can be easily conceived by those skilled in the art are naturally included in the scope of the disclosure. In order to make the explanation clearer, in the drawings, the size, shape, etc. of each part may be changed from the actual embodiment and shown schematically. Corresponding elements in multiple drawings may be denoted by the same reference numerals and detailed descriptions thereof may be omitted.

FIG. 1 is a block diagram showing the configuration of an elevator group management system according to an embodiment, showing a configuration in which a plurality of elevators 12a, 12b, 12c, . . . are group-managed. Note that the number of elevators is arbitrary, and at least two or more are sufficient.

Elevators 12a, 12b, 12c, . . . are double-deck elevators in which two cars are connected vertically. The elevator 12a of the A-car has an upper car 13a and a lower car 14a arranged vertically in one car frame. The upper car 13a and the lower car 14a move up and down in the same direction in the hoistway as one elevator. In this case, for example, when the lower car 14a stops at the first floor, the upper car 13a stops at the second floor. The same applies to the B elevator 12b and the C elevator 12c. The elevator 12b of the B car has an upper car 13b and a lower car 14b, and the elevator 12c of the C car has an upper car 13c and a lower car 14c.

The controllers 11a, 11b, 11c, . The A-car control device 11a controls the operation of the A-car elevator 12a. Specifically, the A car control device 11a controls a motor (hoisting machine) (not shown) for raising and lowering the upper car 13a and the lower car 14a, and controls the opening and closing of doors. The same applies to the B car control device 11b and the C car control device 11c. The controllers 11a, 11b, 11c, .

A first registration device 21 and a second registration device 22 used for a DCS (Destination Control System) are installed at the hall of each floor. The registration devices 21 and 22 are hall destination floor registration devices capable of registering the destination floor of the user at the hall. A DCS in which a destination floor registration device is installed at each floor is called a full DCS. DCS is a system in which the most suitable elevator among a plurality of elevators responds to a call (destination call) having a destination floor registered by a user at a hall.

Here, the first registration device 21 registers a destination call of a specific user who is an object of VIP driving. The second registration device 22 registers destination calls of general users. "VIP operation" is an operation that preferentially provides driving services to specific users, and is also called "exclusive operation". A "specific user" is designated in advance as a target for VIP driving. During the VIP operation, care is taken so that general users do not ride in the same car.

Hereinafter, a destination call (first destination call) registered by operating the first registration device 21 will be referred to as a "VIP call", and a destination call (first destination call) registered by operating the second registration device 22 will be referred to as "VIP call". Destination calls) are distinguished by calling them "normal calls". A VIP call includes information about the destination floor entered by a particular customer and the departure floor where the customer is waiting. The normal call includes information on the destination floor entered by the general user and the departure floor where the user is waiting.

As shown in FIG. 2, the first registration device 21 includes an input unit 21a for inputting a destination floor, and a display unit 21b for notifying the user of the elevator heading to the destination floor input by the input unit 21a. have As for the method of inputting the destination floor, it is common to use a numeric keypad, but a method using an IC card, for example, may also be used. In the example of FIG. 2, it is displayed that the destination floor input by the user is the 13th floor, and that the elevator of the A-type elevator responds as the assigned elevator.

The second registration device 22 has a similar configuration, and includes an input unit 22a for inputting the destination floor and a display unit 21b for notifying the user of the elevator heading to the destination floor input by the input unit 22a. have. In the example of FIG. 1, the first registration device 21 for VIP call registration and the second registration device 22 for normal call registration are separately provided. The configuration may be such that calls and normal calls can be selectively registered.

As shown in FIG. 3, a display device 23 is installed in the vicinity of the hall door 25 in the hall 24 of the A car so that the user can smoothly board the assigned car. The display device 23 is a device for displaying the destination floor of the A car for a predetermined time. In the example of FIG. 3, the 8th floor is displayed as the destination floor of the A car. With such a display, the user can board the train after confirming the destination floor. In the example of FIG. 3, only the display device 23 of car A is shown, but in reality, the display device 23 is installed for each car, and the corresponding destination floor is displayed.

The group supervisory control device 30 is a device that comprehensively controls the operation of the elevators 12a, 12b, 12c, . . . The group supervisory control device 30, like the control devices 11a, 11b, 11c, . In this embodiment, the group supervisory control device 30 includes a first assignment control section 31, a second assignment control section 32, an assignment change section 33, and an assignment command output section . Note that these may be implemented by software, hardware such as an IC (Integrated Circuit), or both software and hardware.

The first allocation control unit 31 performs allocation processing for allocating a VIP call registered by operating the input unit 21a of the first registration device 21 to a VIP number machine. The first allocation control unit 31 has a storage unit 31a that associates and stores a newly registered VIP call and the car to which the VIP call is allocated.

A "VIP elevator" is an elevator that performs VIP operation (dedicated operation) with specific users on board. At least one of the plurality of elevators is preset as a VIP elevator. For example, when the elevator 12a shown in FIG. "A car" is displayed on the display unit 21b as the information of the assigned car.

In addition, when there are two or more VIP cars, the first allocation control unit 31 selects the VIP car that is most suitable for operation efficiency from among these VIP cars, and selects the selected VIP car. Assign a VIP call to the upper or lower car. A VIP car to which a VIP call is assigned is referred to as a "VIP assigned car".

The second allocation control unit 32 performs allocation processing for allocating normal calls registered by operating the input unit 22a of the second registration device 22 to any one of the elevators 12a, 12b, 12c, . The second allocation control unit 32 has a storage unit 32a that associates and stores a newly registered normal call and the car to which the normal call is allocated. A second allocation control unit 32 selects an elevator car that is most suitable for operation efficiency from among the elevators 12a, 12b, 12c, . . . The information of the allocated car is displayed on the display section 22b of the registration device 22. FIG.

The allocation change unit 33 cooperates with the second allocation control unit 32 to change the normal call allocated to the VIP car to another unit when receiving the allocation change instruction from the first allocation control unit 31. Change the assignment to the machine number.

The allocation command output unit 34 receives the information of the allocated car from the first allocation control unit 31 or the second allocation control unit 32, and responds to the allocated car in the control devices 11a, 11b, 11c, . An assignment command is output to the elevator control device to make the assigned elevator respond to the floor where the destination call (VIP call or normal call) is registered at the boarding hall. Also, the destination floor of the assigned car is displayed on the display device 23 installed at the boarding point of the assigned car.

Here, the VIP number is also subject to normal call allocation. However, if a VIP call and a normal call are assigned to a VIP car, there is a possibility that a specific user and a general user ride together in the same car. In addition, even if specific users and general users are separated into separate cars, if general users get off on floors before specific users, VIP operation is not performed (specific users cannot be transported directly to their destination floors). For this reason, if a VIP call has already been assigned to a VIP number machine, the normal call will not be assigned to the VIP number machine, or if the normal call has already been assigned to the VIP number machine, the normal call will be unconditionally transferred to another machine. It is common to reassign specific passengers to one car of the VIP car and operate the other car while the other car is vacant.

On the other hand, in this embodiment, since the DCS is adopted, the destination floor of the user is known in advance. Therefore, if it is judged that "ordinary calls do not affect the response of VIP calls" from the positional relationship between the destination floor and departure floor for normal calls and the destination floor and departure floor for VIP calls, By allocating VIP calls to one car and ordinary calls to the other car, it is possible to efficiently drive specific users and general users on the same VIP car.

"Normal calls do not affect the response of VIP calls" means that "a VIP call driving service (VIP driving) can be implemented". In other words, it means that the assigned VIP call machine can respond to the specific user's departure floor without stopping on the middle floor due to the normal call response, and can go straight from the departure floor to the specific user's destination floor.

In the following, the processing operations of this system will be described separately for (a) ordinary call allocation processing and (b) VIP call allocation processing.

(a) Allocation processing for normal calls FIG. 4 is a flow chart showing allocation processing for normal calls in this system. Here, a process for allocating a newly registered normal call to a VIP number machine to which a VIP call has been allocated will be described. The processing shown in this flowchart is executed by the group supervisory control device 30, which is a computer, reading a predetermined program.

When a normal call is registered by operating the second registration device 22 (Yes in step S1-1), the second allocation control unit 32 provided in the group supervisory control device 30 receives the normal call information (destination floor and departure floor) are given.

First, the second allocation control unit 32 acquires VIP call allocation information from the first allocation control unit 31, and determines whether or not there is a VIP allocated car based on the allocation information (step S1-2). ). A "VIP assigned car" is a VIP car to which a VIP call has already been assigned. For example, assuming that elevator 12a of elevator A is a VIP elevator, it is determined whether a VIP call is assigned to upper car 13a or lower car 14a of elevator 12a.

If there is no VIP-allocated car (No in step S1-2), the second allocation control unit 32 assigns both the upper car and the lower car of the VIP car (step S1-9). In other words, when VIP calls are not assigned to either the upper car 13a or the lower car 14a of the elevator 12a of the A-car, even if a general user rides on the elevator 12a, it is impossible to ride with a specific user. Therefore, the elevator 12a can be included in the allocation target of the normal call.

Here, if there is a VIP-assigned elevator (Yes in step S1-2), the second assignment control unit 32 generates VIP call information (departure floor and destination floor) assigned to the VIP-assigned elevator and , the following processing is performed based on the newly registered normal call information (departure floor and destination floor).

That is, first, the second allocation control unit 32 compares the directivity of the VIP call and the directivity of the normal call (step S1-3). "Direction" means the driving direction from the departure floor to the destination floor. The directionality of a VIP call is determined by the departure floor and destination floor of the VIP call. The directionality of a normal call is determined by the departure floor and destination floor of the normal call. If the directionality of the normal call and the directionality of the VIP call are different, and the normal call is assigned to the VIP-assigned machine, the VIP-assigned machine responds to the normal call, which increases the time until the VIP call is answered. As a result, there is a possibility that the operation service of the VIP call that has registered the VIP call will be degraded. Therefore, when the directionality of the normal call and the directionality of the VIP call are different (No in step S1-3), the second allocation control unit 32 determines that both the upper car and the lower car of the VIP allocated car are not to be allocated. (step S1-8).

On the other hand, if the directionality of the normal call and the directionality of the VIP call are the same (Yes in step S1-3), the second allocation control unit 32 assigns the “destination floor and departure floor” of the VIP call to the normal Based on the positional relationship between the "destination floor and departure floor" of the call, it is determined whether or not the normal call can be assigned to the upper car or lower car of the VIP assigned elevator (steps S1-4 to S1-6). .

Now, assuming that a VIP call is assigned to the upper car of the VIP-assigned elevator, a specific example will be shown in FIG. 5 and explained.
First, the second allocation control unit 32 determines the positional relationship between the departure floor of the normal call and the departure floor/destination floor of the VIP call (step S1-4). In the example of FIG. 5, a VIP call from the 2nd floor to the 8th floor is assigned to the upper car of the VIP-assigned elevator car. Here, since the normal call is assigned to the lower car of the VIP-assigned car, the departure floor of the normal call and the stop floor of the lower car are compared. The stops of the lower car are one floor below the stops of the upper car, so they are the 1st and 7th floors.

Here, if the departure floor of the normal call is neither the 1st floor of the lower car stop floor nor the 7th floor (No in step S1-4), the normal call affects the response of the VIP call. Therefore, the second allocation control unit 32 excludes both the upper car and the lower car of the VIP-allocated car (step S1-8). "Normal calls affect the response of VIP calls" means that "the operation service for VIP calls (VIP operation) cannot be performed". In other words, the elevator to which the VIP call is assigned stops halfway due to the response to the normal call, and it is impossible to give priority to specific users over general users.

Subsequently, the second allocation control unit 32 determines the positional relationship between the destination floors for normal calls and the destination floors for VIP calls (steps S1-5 and S1-6). As shown in FIG. 5, if the destination floor of the normal call is the 7th floor, which is one floor below the destination floor of the VIP call (Yes in step S1-5), allocation is performed to the lower car of the VIP-allocated car. However, it does not affect VIP calls in the upper car. Therefore, the second allocation control unit 32 excludes the upper car of the VIP allocated car from being allocated, and makes the lower car the object of allocation (step S1-7).

Also, if the destination floor of the normal call is the 8th floor, which is the same floor as the destination floor of the VIP call, or the 9th floor, which is one floor above the destination floor of the VIP call (Yes in step S1-6), Even if a normal call is assigned to the lower car of the VIP-assigned car, it does not affect the VIP call in the upper car. Therefore, the second allocation control unit 32 excludes the upper car of the VIP allocated car from being allocated, and makes the lower car the object of allocation (step S1-7).

If the destination floor of the normal call is answered after the destination floor of the destination call, even if the floor is higher than the ninth floor, the lower car can be included in the assignment target. However, in the example of FIG. 5, since there are only up to the 10th floor, up to the 9th floor is the highest floor where the lower car can be operated.

If the conditions of steps S1-5 and S1-6 are not satisfied, the normal call affects the response of the VIP call. It is excluded from allocation (step S1-8).

In this way, even if a VIP call is assigned to one car, if it does not affect the operation service of the VIP call, by assigning a normal call to the other car, Efficient driving can be performed using both the car and the lower car.

In the flowchart of FIG. 4, it is assumed that the VIP call is assigned to the upper car, but the same applies to the case where the VIP call is assigned to the lower car.・Comparing the positional relationship between the destination floor and the departure and destination floors for normal calls, and if it is determined that normal calls do not affect the operation service for VIP calls, the upper car will be included in the allocation target. should be controlled.

(b) VIP Call Allocation Processing FIG. 6 is a flow chart showing the VIP call allocation processing of this system. Here, a description will be given of the process of assigning a newly registered VIP call to a car to which a normal call is assigned and to which a VIP call can be assigned. The processing shown in this flowchart is executed by the group supervisory control device 30, which is a computer, reading a predetermined program.

When the VIP call is registered by operating the first registration device 21 (Yes in step S2-1), the information of the VIP call (destination floor and departure floor) are given.

First, the first allocation control unit 31 allocates the VIP call to the VIP car (elevator for VIP operation) based on the destination floor and departure floor of the VIP call (step S2-1). In this case, the first allocation control unit 31 allocates the VIP call to the car that is most suitable in terms of operational efficiency (the car that can respond to the departure floor earliest) among the upper car and the lower car of the VIP car. . However, since a VIP call has priority over a normal call, if a normal call has already been allocated to a car to which a VIP call is to be allocated, the first allocation control unit 31 changes the allocation through the allocation change unit 33. The allocation of normal calls is changed to another car (step S2-3). As a result, the driving service for VIP calls can be prioritized over normal calls. Note that the assignment change is performed on the assumption that general users do not board the VIP car. When the allocation is changed, the information of the car after the allocation is changed is notified through the display device 23 at the hall.

The above steps S2-1 and S-2 are basic processes for allocating a VIP call to one car of the VIP car. Here, when the normal call is assigned to the other car of the VIP car, the following processing is executed (steps S2-4 to S2-9). If a plurality of normal calls are assigned to the other car of the VIP car, the following process is repeated by the number of normal calls assigned.

Now, assuming that a new VIP call is assigned to the upper car of the VIP car, a specific example will be shown in FIG. 7 and explained.
First, the first allocation control unit 31 acquires the information (departure floor and destination floor) of the normal call registered in the lower car of the VIP car from the second allocation control unit 32, and determines the directionality of the normal call. is the same as that of the VIP call (step S2-4). As described above, "directionality" refers to the driving direction from the departure floor to the destination floor. The directionality of a VIP call is determined by the departure floor and destination floor of the VIP call. The directionality of a normal call is determined by the departure floor and destination floor of the normal call.

If the directionality of the VIP call and the directionality of the normal call are different (No in step S2-4), if the normal call is left assigned to the lower car, the departure floor of the VIP call assigned to the upper car It takes longer to respond. Therefore, the first allocation control unit 31 issues an allocation change command to the allocation change unit 33 to change the allocation of the normal call to another car (step S2-9).

On the other hand, if the directionality of the VIP call and the directionality of the normal call are the same (Yes in step S2-4), the positions of the departure floor/destination floor of the VIP call and the departure floor/destination floor of the normal call Depending on the relationship, even if a normal call is assigned to the lower car of the VIP car, the normal call may not affect the response of the VIP call.

The first allocation control unit 31 determines the positional relationship between the departure floor of the normal call already allocated to the lower car and the departure floor/destination floor of the VIP call (step S2-5). In the example of FIG. 7, a VIP call from the 2nd floor to the 8th floor is assigned to the upper car of the VIP-assigned elevator car. Therefore, the departure and destination floors for VIP calls are the 2nd and 8th floors, which are the stop floors of the upper car.

Here, since the normal call is assigned to the lower car, the departure floor of the normal call and the stop floor of the lower car are compared. The stops of the lower car are one floor below the stops of the upper car, so they are the 1st and 7th floors. If the departure floor of the normal call is neither the 1st floor nor the 7th floor (No in step S1-4), the normal call affects the response of the VIP call. Therefore, the first allocation control unit 31 issues an allocation change command to the allocation change unit 33 to change the allocation of the normal call to another car (step S2-9).

Subsequently, the first allocation control unit 31 determines the positional relationship between the destination floors of ordinary calls and VIP calls already allocated to the lower car (steps S2-6 and S2-7). As shown in FIG. 7, if the destination floor of the normal call is the 7th floor, which is one floor below the destination floor of the VIP call (Yes in step S1-5), the normal call is assigned to the lower car of the VIP car. Even if it remains, it does not affect VIP calls in the upper car. Therefore, the first allocation control unit 31 does not change the allocation of the normal call, but makes the upper car of the VIP car respond to the departure floor of the VIP call (step S2-8).

Also, if the destination floor of the normal call is the 8th floor, which is the same floor as the destination floor of the VIP call, or the 9th floor, which is one floor above the destination floor of the VIP call (step S2-7 Yes), even if the normal call remains assigned to the lower car of the VIP car, it does not affect the VIP call in the upper car. Therefore, the first assignment control unit 31 does not change the assignment of the normal call, but makes the upper car of the VIP car respond to the departure floor of the VIP call (step S2-8).

If the destination floor of the normal call is answered after the destination floor of the destination call, the normal call need not be reallocated even if the floor is higher than the ninth floor. However, in the example of FIG. 7, since there are only up to the 10th floor, up to the 9th floor is the highest floor where the lower car can be operated.

If the conditions of steps S2-6 and S2-7 are not satisfied, the normal call affects the response of the VIP call. Then, the normal call is assigned to another car (step S2-9).

In this way, when a normal call is assigned to one of the cars and does not affect the operation service of the VIP call, the normal call is responded to without changing the assignment, so that the upper car Efficient driving can be performed using both of the lower cages.

In the flowchart of FIG. 6, it is assumed that normal calls are assigned to the lower car. By comparing the positional relationship between the departure floor and the destination floor of the call, if it is judged that there is no effect on the operation service of the VIP call, control should be exercised so as not to change the allocation of the normal call.

According to at least one embodiment described above, it is possible to efficiently load specific users in one car of a double-deck elevator and general users in the other car without impairing the operation service for VIP calls. It is possible to provide an elevator group management system capable of operating in
