Description

TECHNICAL FIELD The present invention relates to control technology for an elevator in which a plurality of cars are provided in one hoistway.

In recent years, the number of high-rise buildings has been remarkable, and elevators have become indispensable as means of transportation in such high-rise buildings. In addition, in a high-rise building, since the number of users increases as the building becomes taller, it is necessary to increase the number of cars in order to efficiently transport users by elevator.

On the other hand, most elevators conventionally used have one car provided in one hoistway. Therefore, if such an elevator is to be applied to a high-rise building, one hoistway must be provided for each car, and in order to increase the number of cars, the number of hoistways must be increased. I didn't.

JP-A-2003-81542

However, when the number of hoistways installed is increased as described above, there is a problem that the occupancy rate of elevators in the building area increases. Therefore, as an elevator capable of solving such a problem, an elevator in which a plurality of cars are provided independently of each other in one hoistway has been proposed (see, for example, Patent Document 1).

On the other hand, in such elevators, each car cannot move past other cars in the same hoistway, so that cars in one hoistway interfere with each other's movement. It was difficult to improve transportation efficiency to a level that could be put into practical use.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a technique capable of significantly improving transportation efficiency in an elevator in which a plurality of cars are provided independently of each other in each hoistway.

The control device according to the present invention can be applied to the following elevators. Here, the elevators are arranged between a specific stop floor and other stop floors in each hoistway, with the first car ascending/descending at a position closest to the specific stop floor being the first car. is an elevator in which up to N-th cars (N is an integer equal to or greater than 2) are provided independently of each other.

The control device includes zone information, a selection processing section, and an allocation processing section. Here, in a section between a specific stopping floor and other stopping floors, one group consisting of a part of consecutive stopping floors among the multiple stopping floors included in the section is defined as one. As zones, N zones are set in order from the 1st closest to a specific stop floor to the Nth, and the zone information includes information about the N zones. When there is a hall call by inputting a destination floor at the hall, the selection processing unit determines whether or not the departure floor is a specific stop floor, and determines whether or not the departure floor is a specific stop floor. Select whether the direction of movement from the departure floor to the destination floor is the same direction or the opposite direction as the specific stop floor, and specify which zone the destination floor belongs to based on the zone information. By doing this systematically, a car to which the hall call can be assigned in each hoistway is selected as an assignment candidate. Specifically, when the selection processing unit determines that the departure floor is "a specific stop floor", the selection processing unit further determines that the destination floor is "the p-th (p is an integer that satisfies 1≤p≤N) zone". , select the p-th car in each hoistway as a candidate for assignment. In addition, when the selection processing unit determines that the departure floor is not a specific stop floor, the selection processing unit further determines that the moving direction is the opposite direction, and the destination floor is the qth (q is q zone", select the q-th car in each hoistway as an allocation candidate. Then, the allocation processing unit extracts any one car from among the allocation candidates selected by the selection processing unit, and allocates the hall call to the car.

According to the control device, it is possible to control the car so as to transport it to the corresponding zone in response to a hall call whose departure floor is a specific stop floor. Elevator operation under such control is hereinafter referred to as "zone operation".

Then, in this zone operation, the range of motion of each car is the range from a specific stop floor to the zone corresponding to itself. Therefore, even when there is a hall call to depart from a stop floor other than a specific stop floor, taking into account such a range of motion, the user is efficiently boarded in the car in the middle of the range of motion. Allocation candidates are selected as follows so that That is, for a hall call to move from a stop floor other than a specific stop floor to a destination floor in the opposite direction to the specific stop floor (inter-floor movement), the zone to which the destination floor belongs (q-th zone) (q-th car) is selected as an allocation candidate. This ensures that each car is efficiently used not only for transport from a specific stop to its own zone, but also for transport from stops within its range of motion to its own zone. Thus, according to the control device, while zone operation is performed from a specific stopping floor, inter-floor movement from stopping floors other than the specific stopping floor in the direction opposite to the specific stopping floor can be efficiently performed. can be made possible.

Consists of a number of continuous stop floors, including a stop floor that serves as a boundary between the M-th zone (M is an integer that satisfies 1≤M≤N-1) and the (M+1)-th zone in the above control device The zone information may further include information on the 1st to (N−1)-th margin intervals, with the M-th margin interval being the group to be processed. The selection processing unit may also be capable of selectively identifying which margin section the destination floor belongs to based on the zone information when there is a hall call. When the selection processing unit determines that the departure floor is not a specific stop floor, the selection processing unit further determines that the moving direction is the opposite direction, and the destination floor is the s-th (where s is q≤s≤N- (integer satisfying 1) margin interval, the s-th and (s+1)-th cars in each hoistway may be selected as allocation candidates.

According to this configuration, when the destination floor belongs to the margin section (s-th margin section), two zones (s-th and (s+1)-th zones) bounded in the margin section Since both of the corresponding cars (s-th and (s+1)-th cars) are selected as allocation candidates, the number of allocation candidates increases to two. By increasing the number of allocation candidates in this way, it becomes possible to extract more optimal cars in allocation processing, and as a result, it becomes possible to improve transportation efficiency.

In the control device described above, the selection processing unit may be capable of selectively identifying which zone the departure floor belongs to based on the zone information when there is a hall call. When the selection processing unit determines that the departure floor is not a specific stop floor, the selection processing unit further determines that the moving direction is the same direction, and the r-th (r is 1 ≤ r ≤ N) regarding the departure floor. (integer satisfying) zone, the r-th through N-th cars in each hoistway may be selected as candidates for assignment.

This configuration utilizes the fact that the r-th to N-th cars can reach the r-th zone in consideration of the range of motion of each car described above. For a hall call to move from a non-specific stopping floor to a destination floor in the same direction as the specific stopping floor (inter-floor movement), the zone to which the departure floor belongs Zones) are selected as allocation candidates. As a result, each car can not only transport from a specific stopping floor to its own zone (transportation by zone operation), but also transport from a stopping floor within its movable range in the same direction as a specific stopping floor (zone operation). transport in the opposite direction). Thus, according to the above configuration, inter-floor movement in the same direction as the specific stopping floor can be efficiently enabled from the stopping floor other than the specific stopping floor.

In the above control device, the selection processing unit may be capable of selectively identifying which margin section the departure floor belongs to based on the zone information when there is a hall call. . When the selection processing unit determines that the departure floor is not a specific stop floor, the selection processing unit further determines that the moving direction is the same direction, and the t-th departure floor (t is 1≤t≤N- 1), the t-th to N-th cars in each hoistway may be selected as allocation candidates.

According to this configuration, if the departure floor belongs to the margin section (t-th margin section), even if the departure floor is on the (t+1)-th zone side, the (t+1)-th to N-th The t-th car belonging to the t-th zone is also selected as an allocation candidate in addition to the cars up to and including the t-th zone, increasing the number of allocation candidates. By increasing the number of allocation candidates in this way, it becomes possible to extract more optimal cars in allocation processing, and as a result, it becomes possible to improve transportation efficiency.

In the control device according to the present invention described above, when the selection processing unit determines that the departure floor is "a specific stop floor", the destination floor is "p-th (p satisfies 1 ≤ p ≤ N a process of selecting the p-th car in each hoistway as an allocation candidate when it is specified that it belongs to the "zone of integer)", and when it is determined that the departure floor is not a specific stop floor, the moving direction are in the same direction, and the departure floor belongs to the r-th zone (r is an integer that satisfies 1 ≤ r ≤ N). and selecting a car as an allocation candidate.

The control device allows each car to be used not only for transport from a specific stop floor to its own zone, but also for transport in which the direction of movement is the same as the specific stop floor. In this way, according to the above control device, while performing zone operation from a specific stopping floor, it is also possible to move between floors from a stopping floor other than the specific stopping floor in the same direction as the specific stopping floor. can do.

As shown in FIG. 2, the elevator is provided with a plurality of hoistways R, and each hoistway R is provided with N cars G (N is an integer equal to or greater than 2). Although not particularly limited, the example of FIG. 2 shows a case where three cars G are provided in each hoistway R (that is, N=3).

In addition, the elevator is provided with a specific stop floor Ft, such as a lobby floor, at which the elevator can be used only after entering the building. In this embodiment, N specific stop floors Ft are provided corresponding to the number (N) of cars G in each hoistway R. In the example of FIG. 2, N stopping floors from the lowest floor among Kr stopping floors F(1) to F(Kr) provided in the elevator are not particularly limited. The case where F(1)-F(N) is a particular stop Ft(1)-Ft(N) is shown.

In each hoistway R, specific stop floors Ft(1) to Ft(N) and other stop floors F (although not limited to a specific stop floor F, which is the highest floor in the example of FIG. 2) (Kr)), the car G (1) to G (N ) are provided independently of each other. The first to Nth cars G(1) to G(N) are associated with specific stopping floors Ft(1) to Ft(N) on a one-to-one basis. For stops to Ft(1) to Ft(N), each car G(n) (where n is a number that satisfies 1≦n≦N) directs itself to its corresponding specific stopping floor Ft(n). Only stopping is allowed.

Furthermore, in the operation section between the specific stop floor Ft (N) and the other stop floor F (in the example of FIG. 2, the stop floor F (Kr), which is the top floor), A group consisting of some continuous stopping floors F among a plurality of stopping floors F (in the example of FIG. 2, stopping floors F(N) to F(Kr)) is specified as one zone Z. N zones Z(1) to Z(N) are set from the 1st closest to the stop floor Ft(N) to the Nth in order. How the zone Z set in this manner is used in elevator control will be described later.

<Destination floor registration device>
The destination floor registration device 101 is installed at the boarding point of each floor (indicated by symbol H in FIG. 1), and device information Pd for identifying each is set in the destination floor registration device 101. ing. Further, each destination floor registration device 101 is provided with a touch panel 1 having both a function as an input unit and a function as a display unit, and the touch panel 1 has an input screen for inputting the destination floor Fd. , a notification screen for conveying various information to the user, and the like are displayed. Here, various types of information displayed on the notification screen include information on the car G to be boarded (in this embodiment, information on the hoistway R on which the car G is provided), a specific stop floor, and so on. When the destination floor Fd is input in any one of Ft(1) to Ft(N), it includes information indicating from which floor the car G should be boarded. Each destination floor registration device 101 is not limited to the touch panel 1, and is provided with an input unit (such as a mechanical button for inputting the destination floor Fd, etc.) and a display unit (such as a monitor dedicated to display) separately. may have been

Information such as the destination floor Fd input through the touch panel 1 is used for elevator control executed by the group supervisory control device 103, which will be described later. Therefore, the destination floor registration device 101 appropriately transmits the information to the group supervisory control device 103 each time the user inputs information such as the destination floor Fd on the touch panel 1 . In addition, the destination floor registration device 101, in order to allow the group supervisory control device 103 to recognize its own position, which is the source of the information, also includes the device information Pd of the destination floor registration device 101 together with information such as the destination floor Fd. It is transmitted to the management control device 103 .

<Elevator controller>
Elevator control devices 102 are provided one by one for each hoistway R, and independently control the operations of N cars G provided on the corresponding hoistway R (Fig. 1). reference). The elevator controller 102 is centrally managed and controlled by the group supervisory controller 103 .

<Group supervisory control device>
The group supervisory control device 103 has a storage unit 2 and a control unit 3 (see FIG. 1).

The storage unit 2 is a memory such as a ROM or a RAM, and various information necessary for elevator control is stored in the storage unit 2 . In this embodiment, device management data Dd and zone information Dz are stored in the storage unit 2 as information necessary for elevator control.

FIG. 3A is a conceptual diagram showing an example of device management data Dd. As shown in FIG. 3A, the device management data Dd includes, for each device information Pd of the destination floor registration device 101, a device address Pa and an installation floor Fs, which are other information related to the destination floor registration device 101. They are associated and stored in advance. Here, the device address Pa is an address (such as an IP address) used for controlling the operation of the destination floor registration device 101 identified by the device information Pd and for transmitting information to the destination floor registration device 101 . The installation floor Fs is the floor where the destination floor registration device 101 identified by the device information Pd is installed.

FIG. 3B is a conceptual diagram showing an example of zone information Dz used in the embodiment. As shown in FIG. 3(B), the zone information Dz includes information on N zones Z(1) to Z(N) set within the service section. Specifically, in the zone information Dz, for each zone Z, a stop floor F belonging to that zone Z is associated. In FIGS. 2 and 3B, the number of the stop floor F, which is the boundary between two vertically adjacent zones Z, is represented by m. More specifically, for (N−1) boundaries formed by N zones Z(1) to Z(N), the numbers of the stopping floors F that form the (N−1) boundaries are respectively It is represented by m(1) to m(N-1).

The control unit 3 is a processing device such as a CPU. Then, there is a hall call (input of the destination floor Fd at the hall), and the group supervisory control device 103 receives the information necessary for elevator control (including the destination floor Fd and the device information Pd) from the destination floor registration device 101. In this case, the control unit 3 executes a selection process and an allocation process as control processes for controlling the elevator. Specifically, it is as follows.

In the selection process, the control unit 3 selects the stop floor F (in the present embodiment, the installation floor Fs of the destination floor registration device 101 for which the destination floor Fd has been input) at which the landing for which the destination floor Fd has been input is located. As the departure floor Fc, it is determined whether or not the departure floor Fc is a specific stopping floor Ft, and the movement direction Dm from the departure floor Fc to the destination floor Fd is the same or opposite to the specific stopping floor Ft. Determining which one it is, specifying which zone Z the destination floor Fd belongs to based on the zone information Dz, and specifying which zone Z the departure floor Fc belongs to based on the zone information Dz and are selectively performed, a car G to which the hall call can be assigned in each hoistway R is selected as an assignment candidate Gc. In this embodiment, the control unit 3 can execute the following processes (1) to (3) as the selection process.

(1) When the control unit 3 determines that the departure floor Fc is "a specific stop floor Ft", the control unit 3 further determines that the destination floor Fd is "the p-th (p is an integer satisfying 1≤p≤N) zone Z(p)”, the p-th car G(p) in each hoistway R is selected as an allocation candidate Gc.

(2) When the control unit 3 determines that the departure floor Fc is not the specific stop floor Ft, it further determines that the moving direction Dm is the opposite direction, and the destination floor Fd is the q If the car is identified as belonging to the th (q is an integer that satisfies q≦N) zone Z(q)”, the qth car G(q) in each hoistway R is selected as an allocation candidate Gc.

(3) When the control unit 3 determines that the departure floor Fc is "not a specific stop floor Ft", it further determines that the moving direction Dm is "same direction" and also determines that the departure floor Fc is "r th (r is an integer satisfying 1≦r≦N) zone Z(r)”, the r-th to N-th cars G(r) to G in each hoistway R (N) is selected as an allocation candidate Gc.

In the allocation process, the control unit 3 extracts one optimum car G from among the allocation candidates Gc selected in the selection process in consideration of the operation status, etc., and allocates the hall call to the car G. .

In this embodiment, the selection processing and the allocation processing are executed by the selection processing section 31 and the allocation processing section 32 respectively configured in the control section 3 (see FIG. 1). Specifically, these processing units are composed of software by causing a processing device (such as a CPU), which is the control unit 3, to execute a program, and such a program is stored in the storage unit 2. ing. The program may be stored in a portable storage medium in a readable state, read from the storage medium and stored in the storage unit 2, or may be stored in a server or the like so as to be downloaded, Those downloaded from the server may be stored in the storage unit 2 . Note that the above processing unit may be configured by hardware by constructing the control unit 3 in the group supervisory control device 103 with a circuit.

Details of control processing (including selection processing and allocation processing) executed by the group supervisory control device 103 will be described below.

[2] Control Processing Executed by Group Supervisory Control Device FIG. 4 is a flow chart showing control processing executed in this embodiment. In this control process, there is a hall call (input of the destination floor Fd at the hall), and information necessary for elevator control (including the destination floor Fd and device information Pd) is sent by the group supervisory control device 103 to the destination floor registration device 101. is started when received from

When the control process is started, the control unit 3 of the group supervisory control device 103 uses the device information Pd included in the information (received information Pr) received from the destination floor registration device 101 to extract from the device management data Dd , the device address Pa and installation floor Fs corresponding to the device information Pd are read (step S100). Since the installation floor Fs read out here matches the stop floor F where the hall call (input of the destination floor Fd at the hall) is made, the user who made the hall call should board the car G. can be used as the departure floor Fc.

Therefore, the control unit 3 determines whether the user who has called the platform intends to board from a specific stop floor Ft or from a stop floor F other than the specific stop floor Ft. Assuming that the installation floor Fs read in step S100 is the departure floor Fc, it is determined whether or not the departure floor Fc is a specific stop floor Ft (step S101). Specifically, the control unit 3 determines whether or not the departure floor Fc matches any one of the specific stopping floors Ft(1) to Ft(N), thereby determining whether the departure floor Fc is the specific stopping floor Ft. Determine whether or not

If the control unit 3 determines in step S101 that "it is a specific stop floor Ft (Yes)", then it is determined that the user who called the platform intends to get on from the specific stop floor Ft. can be judged. In this case, the control unit 3 identifies which zone Z the destination floor Fd in the received information Pr belongs to based on the zone information Dz (see FIG. 3B) (step S102). Specifically, by referring to the zone information Dz, the control unit 3 extracts the number of the zone Z associated with the stop floor F that matches the destination floor Fd in the received information Pr. A zone Z to which the destination floor Fd belongs is specified.

Then, if the control unit 3 determines in step S102 that the destination floor Fd belongs to the "p-th (p is an integer satisfying 1≤p≤N) zone Z(p)", The p-th car G(p) in the list is selected as an allocation candidate Gc (step S103), and then the process proceeds to the allocation process. In step S103, the p-th car G(p) for each hoistway R is selected as an allocation candidate Gc, so the number of allocation candidates Gc increases according to the number of hoistways R.

In the assignment process in this case, the control unit 3 selects from among the assignment candidates Gc (the p-th car G(p) selected for each hoistway R) selected in step S103, taking into consideration the operation status and the like. One optimum car G is extracted, and the hall call (departure floor Fc and destination floor Fd) to be processed at that time is assigned to the car G.

Then, the control unit 3 displays a notification screen for notifying the user of the information of the hoistway R in which the car G to which the hall call is assigned is provided (for example, the information of which entrance to get on), It is displayed on the touch panel 1 of the destination floor registration device 101 specified by the device address Pa read in step S100. In addition to the information on the hoistway R, information such as the destination floor Fd input by the user may be displayed on the notification screen.

Here, in this embodiment, the cars G(1) to G(N) in each hoistway R are permitted to stop only at their corresponding specific stop floors Ft(1) to Ft(N). It is Therefore, when a user makes a hall call at one of the specific stop floors Ft(1) to Ft(N), the floor at the time of making the hall call is assigned to the hall call. It may happen that the elevator car G is at a floor other than the specific stop floor Ft at which it can stop. In this case, the control unit 3 further displays a specific stop floor Ft on which the assigned car G can stop on the notification screen, and prompts the user to move to that floor by an escalator or the like. may

According to such selection processing (steps S101 to S103) and allocation processing, in response to a hall call with a specific stop floor Ft as the departure floor Fc, the car G is transported to the corresponding zone Z. can be controlled to do so. Elevator operation under such control is hereinafter referred to as "zone operation".

In this zone operation, the range of motion of each car G is from a specific stop floor Ft to the zone Z corresponding to itself. Therefore, in the present embodiment, even if there is a hall call with a departure floor Fc from a stop floor F other than a specific stop floor Ft, such a range of motion is taken into account and the car G is moved in the middle of the range of motion. The following control is performed so that the user can be efficiently boarded.

If the control unit 3 determines in step S102 that it is not the specific stop floor Ft (No), then the user who called the platform can start from the stop floor F other than the specific stop floor Ft. It can be determined that you are about to board. In this case, the control unit 3 determines whether the user intends to move upward or downward, so that the movement direction Dm from the departure floor Fc to the destination floor Fd is determined by the specific stop floor Ft. It is determined whether it is in the same direction or in the opposite direction (step S110). In the example of FIG. 2, the same direction as the specific stopping floor Ft corresponds to the downward direction, and the opposite direction to the specific stopping floor Ft corresponds to the upward direction.

If the control unit 3 determines in step S110 that the movement direction Dm is the "reverse direction" (upward direction in the example of FIG. 2), based on the zone information Dz (see FIG. 3B), It is specified which zone Z the destination floor Fd belongs to (step S111). Specifically, by referring to the zone information Dz, the control unit 3 extracts the number of the zone Z associated with the stop floor F that matches the destination floor Fd, and the destination floor Fd belongs to that number. Identify zone Z.

Then, when the control unit 3 determines in step S111 that the destination floor Fd belongs to the “q-th (q is an integer satisfying q≦N) zone Z(q)”, The q-th car G(q) is selected as an allocation candidate Gc (step S112), and then shifts to allocation processing. In step S112, since the q-th car G(q) for each hoistway R is selected as the allocation candidate Gc, the number of allocation candidates Gc increases according to the number of hoistways R.

In the assignment process in this case, the control unit 3 selects from among the assignment candidates Gc selected in step S112 (the q-th car G(q) selected for each hoistway R), considering the operation status and the like. One optimum car G is extracted, and the hall call (departure floor Fc and destination floor Fd) to be processed at that time is assigned to the car G.

According to such selection processing (steps S101, S110 to S112) and allocation processing, from a stop floor F other than the specific stop floor Ft, the direction opposite to the specific stop floor Ft (upward in the example of FIG. 2) In response to a hall call for movement to a certain destination floor Fd (inter-floor movement), a car G (q-th boarding Car G(q)) is selected as an allocation candidate Gc. As a result, each car G can efficiently transport not only from a specific stopping floor Ft to its own zone Z (transportation by zone operation), but also from a stopping floor F within its movable range to its own zone Z. It will be used well. In this way, according to the control process described above, while zone operation is performed from a specific stopping floor Ft, an interfloor operation from a stopping floor F other than the specific stopping floor Ft in the direction opposite to the specific stopping floor Ft is performed. Movement can also be efficiently enabled.

On the other hand, if the control unit 3 determines in step S110 that the movement direction Dm is "same direction", it determines what number the departure floor Fc is based on the zone information Dz (see FIG. 3B). Whether it belongs to zone Z is specified (step S121). Specifically, the control unit 3 refers to the zone information Dz to extract the number of the zone Z associated with the stop floor F that matches the departure floor Fc, and the departure floor Fc belongs to that number. Identify zone Z.

Then, when the control unit 3 determines in step S121 that the departure floor Fc belongs to the “r-th (r is an integer satisfying 1≦r≦N) zone Z(r)”, each hoistway R The r-th to N-th cars G(r) to G(N) are selected as allocation candidates Gc (step S122), and then shift to allocation processing. In step S122, since the r-th to N-th cars G(r) to G(N) for each hoistway R are selected as allocation candidates Gc, the number of allocation candidates Gc is equal to the number of hoistways R. will increase accordingly.

In the allocation process in this case, the control unit 3 selects from among the allocation candidates Gc (cars G(r) to G(N) selected for each hoistway R) selected in step S122, and considers the operation status. Then, one optimum car G is extracted, and the hall call (departure floor Fc and destination floor Fd) to be processed at that time is assigned to the car G.

Such selection processing (steps S101, S110, S121 to S122) and assignment processing take into consideration the range of motion of each car G described above, and from r-th to N-th zones to r-th zone Z(r). This is based on the fact that the cars G(r) to G(N) can reach each other. In response to a hall call for movement (inter-floor movement) from a stop floor F other than a specific stop floor Ft to a destination floor Fd in the same direction as the specific stop floor Ft (downward in the example of FIG. 2) Then, the car G (r-th to N-th cars G(r) to G(N)) that can reach the zone Z (r-th zone Z(r)) to which the departure floor Fc belongs is It will be selected as an allocation candidate Gc. As a result, each car G can not only transport from a specific stopping floor Ft to its own zone Z (transportation by zone operation), but also can move from a stopping floor F within its movable range in the same direction as the specific stopping floor Ft. It will also be used efficiently for transport (transport in the opposite direction to zone operation). Thus, according to the above-described control process, inter-floor movement from a stop floor F other than the specific stop floor Ft in the same direction as the specific stop floor Ft can be efficiently enabled.

Thus, according to the group supervisory control device 103 of the present embodiment and the above-described control process executed by it, in an elevator in which a plurality of cars G are independently provided in each hoistway R, a specific While the zone operation from the stop floor Ft is efficiently performed, transportation from the stop floors F other than the specific stop floor Ft can also be efficiently performed, and the transportation efficiency can be significantly improved.

[3] Modification [3-1] First Modification FIG. 5 is a conceptual diagram showing various settings used in the first modification together with the configuration of the elevator. As shown in FIG. 5, in each hoistway R, a margin section Y is set in addition to the zone Z in the present modification. Here, the margin section Y is a group composed of several stopping floors F including a stopping floor F(m) that serves as a boundary between two zones Z that are vertically adjacent to each other. Here, the stop floor F(m) is the number of the stop floor F, which is the boundary between two zones Z that are vertically adjacent to each other, represented by m. In the following, for (N−1) boundaries formed by N zones Z(1) to Z(N), the numbers of stopping floors F that form the (N−1) boundaries are m (1) to m(N-1) (see FIG. 5).

Specifically, the margin section Y is set as follows. That is, the stopping floor F(m(M)), which is the boundary between the Mth (M is an integer satisfying 1≦M≦N−1) zone Z(M) and the (M+1)th zone Z(M+1), is A group consisting of a number of consecutive stopping floors F, including F, is set as the M-th margin section Y(M). In the example of FIG. 5, the margin section Y(M) is a stopping floor F(m(M)−k) (k is an integer equal to or greater than 1) centered on the stopping floor F(m(M)) serving as the boundary. to the stopping floor F(m(M)+k) (2k+1) stopping floors F.

Note that the margin section Y(M) is defined by the number of stopping floors F below the boundary stopping floor F(m(M)) among the stopping floors F included in the section, and the number of stopping floors F ( The number of stop floors F above m(M)) may be changed as appropriate. In addition, the margin section Y(M) may be appropriately changed to be composed only of the stopping floor F(m(M)) as a boundary and the stopping floor F above that floor, The stop floor F(m(M)) serving as a boundary and the stop floor F below that floor may be changed as appropriate. Furthermore, the width of the margin section Y(M) (the width from the lower floor to the upper floor of the stop floors F constituting the margin section Y(M)) may be set to a different width for each hoistway R. Alternatively, it may be changed according to the time period.

In the zone information Dz, in addition to the information about the N zones Z(1) to Z(N), margin intervals Y(1) to Y(N-1) from the 1st to the (N-1)th ) is further included. FIG. 6 is a conceptual diagram showing an example of zone information Dz used in this modification.

In the selection process, the control unit 3 of the group supervisory control device 103 specifies which margin section Y the destination floor Fd belongs to based on the zone information Dz, and determines what the departure floor Fc belongs to based on the zone information Dz. It is also possible to selectively specify whether it belongs to the th margin section Y, and the allocation candidate Gc can be selected by executing the following processes (4) and (5) as the selection process. .

(4) When the control unit 3 determines that the departure floor Fc is not a specific stop floor Ft, it further determines that the moving direction Dm is the opposite direction, and the destination floor Fd is s th (s is an integer that satisfies q≦s≦N−1) margin section Y(s)”, the sth and (s+1)th cars G ( s) and G(s+1) as allocation candidates Gc.

(5) When the control unit 3 determines that the departure floor Fc is "not a specific stop floor Ft", it further determines that the movement direction Dm is "same direction", and further determines that the departure floor Fc is "t th (t is an integer that satisfies 1≦t≦N−1)”, the t-th to N-th cars G(t) to G(N) is selected as an allocation candidate Gc.

Then, in the allocation process, as in the above-described embodiment, the control unit 3 extracts one optimum car G from among the allocation candidates Gc selected in the selection process in consideration of the operation status and the like, and The hall call is assigned to car G.

FIG. 7 is a flowchart showing control processing executed in this modification. In this modification, when the control unit 3 determines in step S110 that the moving direction Dm is the "reverse direction", it determines whether the destination floor Fd belongs to any margin section Y or whether the margin Whether or not the destination floor Fd belongs to any margin section Y based on the zone information Dz (see FIG. 6) in order to determine whether it belongs to any zone Z and not to any section Y is determined (step S200).

When the controller 3 determines in step S200 that it does not belong to any margin section Y (No), the destination floor Fd belongs to only one zone Z. can be determined to be In this case, the control unit 3 selects the allocation candidate Gc by identifying which zone Z the destination floor Fd belongs to, and then , shifts to allocation processing.

On the other hand, if the control unit 3 determines in step S200 that "it belongs to any margin section Y (Yes)", based on the zone information Dz (see FIG. 6), the destination floor Fd is of what number. Whether it belongs to the margin section Y is specified (step S201). Specifically, by referring to the zone information Dz, the control unit 3 extracts the number of the margin section Y associated with the stop floor F that matches the destination floor Fd. Identify the margin section Y to which it belongs.

Then, when the control unit 3 determines in step S201 that the destination floor Fd belongs to the “s-th (s is an integer satisfying q≦s≦N−1) margin section Y(s)”, each The s-th and (s+1)-th cars G(s) and G(s+1) in the hoistway R are selected as allocation candidates Gc (step S202), and then the process proceeds to the allocation process. In step S202, the s-th and (s+1)-th cars G(s) and G(s+1) for each hoistway R are selected as allocation candidates Gc. will increase according to the number of

In the allocation process in this case, the control unit 3 selects allocation candidates Gc (s-th and (s+1)-th cars G(s) and G(s+1) selected for each hoistway R) selected in step S202. From among them, one optimum car G is extracted in consideration of the operation status, etc., and the hall call (departure floor Fc and destination floor Fd) to be processed at that time is assigned to the car G.

According to such selection processing (steps S101, S110, S200 to S202) and assignment processing, if the destination floor Fd belongs to the margin section Y(s), the boundary Since the cars G(s) and G(s+1) corresponding to the two zones Z(s) and Z(s+1), respectively, are selected as allocation candidates Gc, the number of allocation candidates Gc is reduced to two. will increase. By increasing the number of allocation candidates Gc in this way, it becomes possible to extract a more optimal car G in allocation processing, and as a result, it becomes possible to improve transportation efficiency.

If the control unit 3 determines in step S110 that the direction of movement Dm is "same direction", it determines whether the departure floor Fc belongs to any margin section Y or whether the margin section Y In order to determine whether the departure floor Fc belongs to any zone Z without belonging to it, it is determined whether or not the departure floor Fc belongs to any margin section Y based on the zone information Dz (see FIG. 6). (Step S210).

If the controller 3 determines in step S210 that it does not belong to any margin zone Y (No), then the departure floor Fc belongs to only one zone Z. can be determined to be In this case, the control unit 3 selects an allocation candidate Gc by identifying which zone Z the departure floor Fc belongs to, and then , shifts to allocation processing.

On the other hand, if the control unit 3 determines in step S210 that "it belongs to any margin section Y (Yes)", based on the zone information Dz (see FIG. 6), the control unit 3 determines which floor the departure floor Fc belongs to. Whether it belongs to the margin section Y is specified (step S211). Specifically, the control unit 3 refers to the zone information Dz to extract the number of the margin section Y associated with the stop floor F that matches the departure floor Fc. Identify the margin section Y to which it belongs.

Then, when the control unit 3 determines in step S211 that the departure floor Fc belongs to the “t-th (t is an integer satisfying 1≦t≦N−1) margin section Y(t)”, t 1st to Nth cars G(t) to G(N) are selected as allocation candidates Gc (step S212), and then shift to allocation processing. In step S212, the t-th to N-th cars G(t) to G(N) for each hoistway R are selected as allocation candidates Gc. The number will increase accordingly.

In the allocation process in this case, the control unit 3 selects among allocation candidates Gc (t-th to N-th cars G(t) to G(N) selected for each hoistway R) selected in step S212. , one optimum car G is extracted in consideration of the operation status, etc., and the hall call (departure floor Fc and destination floor Fd) to be processed at that time is assigned to the car G.

According to the selection process (steps S101, S110, S210 to S212) and the allocation process, if the departure floor Fc belongs to the margin section Y(t), the departure floor Fc belongs to the zone Z(t+1). In addition to the cars G(t+1) to G(N), the car G(t) belonging to the zone Z(t) is also selected as the allocation candidate Gc, and the number of the allocation candidates Gc increases. It will be. By increasing the number of allocation candidates Gc in this way, it becomes possible to extract a more optimal car G in allocation processing, and as a result, it becomes possible to improve transportation efficiency.

Any one of them may be executed as appropriate, or some or all of them may be executed as appropriate.

[3-3] Third Modification In the above-described elevator, the number of cars G (N) in each hoistway R and the same number of stopping floors F are the specific stopping floors Ft (Fig. 2 , FIG. 5), but the number of specific stop floors Ft may be less than the number of cars G (N). For example, the number of specific stop floors Ft may be one. In such a case, in order to allow any car G in each hoistway R to stop at a specific stopping floor Ft, below a specific stopping floor Ft, A garage floor is provided for evacuating another car G upon its arrival at Ft. The above-described control process can also be applied to such an elevator.
