2. Operation The operation of the elevator system of this embodiment will be described.

2-1. Specific Operation of Destination Floor Registration Device The operation of the destination floor registration devices 210 and 310 will be described. FIG. 7 is a flow chart showing an example of the operation of the destination floor registration devices 210 and 310. As shown in FIG.

The processing shown in FIG. 7 is executed by destination floor registration devices 210 and 310 installed on non-common floors (2nd to 9th floors, 11th to 20th floors). Each of the destination floor registration devices 210 and 310 constantly executes the processing shown in FIG. A case where the destination floor registration device 210 for the low-rise bank executes the processing of FIG. 7 will be described below. Since the same applies to the case where the destination floor registration device 310 for the high-rise bank executes the processing of FIG. 7, the description is omitted.

The destination floor registration device 210 determines whether or not a destination floor has been designated (S1). The control unit 211 of the destination floor registration device 210 determines that the destination floor has been designated when a signal based on the designation operation of the destination floor is received from the operation unit 215 . The signal includes destination floor information corresponding to the designation operation of the operation unit 215 .

If the destination floor is not specified (NO in S1), the control unit 211 of the destination floor registration device 210 executes step S1 again.

If a destination floor is specified (YES in S1), the destination floor registration device 210 transmits an allocation request signal to the group supervisory control device 100 (S2). The control unit 211 of the destination floor registration device 210 includes the departure floor and destination floor information in the allocation request signal. The “departure floor” is stored, for example, in the storage unit 212 of each destination floor registration device 210 as information of the floor where the destination floor registration device 210 is installed. The control unit 211 reads the departure floor from the storage unit 212 and uses it when generating the allocation request signal. Similarly, the control unit 211 uses the destination floor information included in the signal transmitted from the operation unit 215 when generating the allocation request signal.

Destination floor registration device 210 determines whether or not an allocation result signal has been received from group supervisory control device 100 (S3). The allocation result signal is a signal transmitted from the group supervisory control device 100 in response to the allocation request signal, and includes at least the information of the allocated car. The assigned car is one car assigned by the group supervisory control device 100 from among all the cars (A car to F car).

If no allocation result signal has been received from the group supervisory control device 100 (NO in S3), the destination floor registration device 210 executes step S3 again.

If the allocation result signal is received from the group supervisory control device 100 (YES in S3), the destination floor registration device 210 determines whether or not the information of the "transfer floor" is included in the allocation result (S4). "Transfer floor" refers to a floor in a bank whose destination floor is different from the departure floor included in the allocation request signal, and when an elevator transfer is required, any floor among a plurality of common floors (1st floor, 10th floor) This is information for specifying whether to change trains at.

If the departure floor and the destination floor included in the assignment request signal are in the same bank and no transfer is required, the transfer floor is not included in the assignment result (NO in S4). The control unit 212 of the destination floor registration device 210 causes the display unit 215 to display the "allocated car" indicated by the allocation result signal for a predetermined time (S5). The predetermined time is a length of time during which the user can visually recognize the assigned car, for example, 4 seconds.

A display example of the destination floor registration device 210 regarding step S5 is shown in FIGS. 8A and 8B.

As an example, FIG. 8A shows an example in which the 8th floor is registered as the destination floor (YES in S1), and FIG. 8B shows an example in which the assigned elevator corresponding to the destination floor of the 8th floor is the A elevator (S5). .

If the transfer floor is included in the allocation result (YES in S4), the control unit 212 of the destination floor registration device 210 causes the display unit 215 to display the "allocated car" and "transfer floor" indicated by the allocation result signal for a predetermined time. (S6). The predetermined time is a length of time during which the user can visually recognize the assigned car and the transfer floor, for example, 6 seconds. The display time of the assigned elevator car and transfer floor in step S6 may be longer than the display time of the assigned elevator car in step S5 according to the amount of information to be displayed.

As display examples of the destination floor registration device 210 relating to step S6, a display example 1 is shown in FIGS. 9A and 9B, and a display example 2 is shown in FIGS. 10A and 10B.

Regarding display example 1, FIG. 9A shows an example in which the 18th floor is registered as the destination floor (YES in S1), and FIG. is the tenth floor (S6).

Regarding display example 2, FIG. 10A shows an example in which the 13th floor is registered as the destination floor (YES in S1), and FIG. is the first floor (S6).

As described above, when a destination floor requiring a transfer between different banks is registered in the destination floor registration devices 210 and 310, the elevator system automatically determines the transfer floor, and the destination floor registration devices 210 and 310 Information about the transfer floor is displayed on the display units 214 and 314 of , (FIGS. 9B and 10B). Even if there are a plurality of transfer floor candidates (common floors), the transfer floor information displayed on the destination floor registration devices 210 and 310 may be used as the basis for the transfer, so the user does not need to select and set the transfer floor. You can save the trouble. For example, if the user operates the destination floor registration device 210 for the low-rise bank, the user does not need to operate the destination floor registration device 310 again for the high-rise bank after arriving at the transfer floor, and the destination floor registration device for the low-rise bank does not need to be operated again. It is possible to move between different banks with a single operation at 210 . In this way, user convenience can be improved.

The transfer floor may also be determined by the elevator system based on various parameters such as the time required to reach the transfer floor. As a result, it is possible to operate the elevator with improved operational performance and user convenience. Details will be described later.

2-2. Specific Operations of Group Supervisory Control Device Specific operations of the group supervisory control device 100 will be described. FIG. 11 is a flowchart showing an example of processing performed when the group supervisory control device 100 receives allocation request signals from the destination floor registration devices 210 and 310 .

The control unit 101 of the group supervisory control device 100 determines whether or not the departure floor and the destination floor included in the allocation request signals received from the destination floor registration devices 210 and 310 are floors of different banks (S11). When receiving an allocation request signal from the destination floor registration device 210 for the low-rise bank, the departure floor is a low-rise floor (2nd to 9th floors), so if the destination floor is a high-rise floor (11th to 20th floors) , that the departure floor and the destination floor are in different banks (YES in S11). When an allocation request signal is received from the destination floor registration device 310 for a high-rise bank, the departure floor is a high-rise floor (11th to 20th floors), so if the destination floor is a low-rise floor (2nd to 9th floors) , the departure floor and the destination floor are determined to be floors of different banks.

On the other hand, if the departure floor and the destination floor are in the same bank, it is determined that they are not in different banks (NO in S11), and the control unit 101 of the group supervisory control device 100 determines the assigned car (S12). . When receiving an allocation request signal from the destination floor registration device 210 for the low-rise bank, the control unit 101 determines the allocated elevator from among the six low-rise bank elevators 230 (A-F). When receiving an allocation request signal from the destination floor registration device 310 for the high-rise bank, the control unit 101 determines the assigned elevator from among the six high-rise bank elevators 330 (G to L).

If the departure floor and the destination floor are in the same bank, the destination floor can be reached by either the low-rise bank elevator 230 or the high-rise bank elevator 330, so there is no need to change trains. Therefore, the control unit 101 of the group supervisory control device 100 does not set the transfer floor, but determines only the assigned car.

The assigned number is determined, for example, based on the assigned evaluation value, which is an index related to transportation performance. The control unit 101 of the group supervisory control device 100 obtains an allocation evaluation value for each car, assigns a destination floor call to a car having an allocation evaluation value indicating optimum allocation among the obtained allocation evaluation values, and assigns the car to the allocated car. to decide. A known method can be used for the allocation method based on the allocation evaluation value. For example, it is possible to use an allocation method that minimizes the sum of waiting times and the sum of service completion times for all machines and all calls.

The group supervisory control device 100 transmits the allocation result signal to the destination floor registration device and the elevator car control device (S13). When receiving an allocation request signal from the destination floor registration device 210 for the low-rise bank, the control unit 101 controls the destination floor registration device 210 that transmitted the allocation request signal and the elevator car control device 220 corresponding to the allocated elevator car determined in step S12. send an allocation result signal to When the allocation request signal is received from the destination floor registration device 310 for the high-rise bank, the control unit 101 connects the destination floor registration device 310 that transmitted the allocation request signal and the elevator car control device 320 corresponding to the assigned elevator determined in step S12. send an allocation result signal to The allocation result signal includes information on the allocated car determined in step S12.

As described with reference to FIGS. 7 and 8B, the destination floor registration device 210 that has received the allocation result signal from the group supervisory control device 100 displays "allocated car" on the display unit 214 for a predetermined time (S5). Similarly, when the destination floor registration device 310 receives the allocation result signal, the display unit 314 displays "allocated car" for a predetermined time (S5).

When it is determined that the departure floor and the destination floor are in different banks (YES in S11), the control unit 101 determines the first assigned car and transfer floor (S14). When receiving an allocation request signal from the destination floor registration device 210 for the low-rise bank, the control unit 101 determines the first allocated elevator from among the six low-rise bank elevators 230 (A-F). A transfer floor is determined from among two common floors (1st floor and 10th floor). When an allocation request signal is received from the high-rise bank destination floor registration device 310, the control unit 101 determines the first allocated elevator from among the six high-rise bank elevators 330 (G-to-L). A transfer floor is determined from among two common floors (1st floor and 10th floor).

The details of the determination process (S14) of the first assigned car and transfer floor will be described with reference to FIG. FIG. 12 is a flow chart showing an example of the process of determining the first assigned car and the transfer floor of the group supervisory control device 100 according to the first embodiment.

As shown in FIG. 12, the group supervisory control device 100 determines the time required to reach the first common floor when each elevator is assigned the first common floor, and the time required to reach the first common floor when the second common floor is assigned. 2 and the time required to reach the common floor are calculated (S14-1). For example, when an allocation request signal is received from the destination floor registration device 210 for the low-rise bank, the control unit 101 of the group supervisory control device 100 performs transfer for each of the six low-rise bank elevators 230 (A to F). The required time to reach the 1st floor when the 1st floor is assigned as a floor candidate and the required time to arrive at the 10th floor when the 10th floor as a transfer floor candidate is assigned are calculated. When receiving an allocation request signal from the high-rise bank destination floor registration device 310, the control unit 101 of the group supervisory control device 100 selects transfer floor candidates for each of the six high-rise bank elevators 330 (G-to-L). and the time required to reach the 10th floor when the 10th floor, which is a transfer floor candidate, is assigned. The group supervisory control device 100, for example, based on the current position of each elevator, the number of floors up to the common floor, the call registered at the floor on the way to the common floor, etc., determines the traveling time between floors, The time required for each elevator to reach the common floor is calculated by obtaining the stop time at the floor and accumulating these times. This "required time" is an evaluation regarding the operation of elevator 230, and is also referred to as a "first evaluation".

The group supervisory control device 100 determines the first assigned elevator and transfer floor based on the combination of the elevator and the common floor that takes the shortest required time (S14-2). The control unit 101 of the group supervisory control device 100 identifies a combination of elevator cars and common floors that provides the shortest required time from among the plurality of required times calculated in step S14-1, and determines the combination of elevator cars and common floors that constitute the combination. are respectively set to the first assigned car and the transfer floor.

According to the above determination method, the time required to reach the transfer floor can be minimized, and convenience for the user can be improved.

After determining the first allocated car and transfer floor, the control unit 101 of the group supervisory control device 100 transmits a first allocation result signal to the destination floor registration device and the car control device (S15). When the allocation request signal is received from the destination floor registration device 210 for the low-rise bank, the control unit 101 sends the first allocation result signal to the destination floor registration device 210 that transmitted the allocation request signal and the first allocation elevator. It is transmitted to the elevator control device 220 . When an allocation request signal is received from the destination floor registration device 310 for a high-rise bank, the control unit 101 sends the first allocation result signal to the destination floor registration device 310 that transmitted the allocation request signal and to the first allocated car. It is transmitted to the elevator control device 320 . The first allocation result signal includes information on the first allocated car and transfer floor determined in step S14.

As described with reference to FIGS. 7, 9B, and 10B, the destination floor registration device 210, which receives the first allocation result signal from the group supervisory control device 100, causes the display unit 214 to display "allocated car (first allocated car)". and "change floor" are displayed for a predetermined time (S6). Similarly, when the destination floor registration device 310 receives the allocation result signal, the display unit 314 displays "assigned car (first assigned car)" and "transfer floor" for a predetermined time (S6).

The car controllers 220 and 320 that have received the first assignment result signal from the group supervisory control device 100 cause the in-car display of the first assigned car to display information about the transfer floor. A specific display example is shown in FIG.

FIG. 13 is a diagram showing a display example of the in-car indicator 400 of the first assigned car. The in-car display device 400 shown in FIG. 13 displays the characters "Transfer guide", the characters "Transfer floor → 10th floor", and the characters "*Transfer car will be guided before arrival.". Similarly, when the transfer floor is the first floor, the characters "transfer floor→first floor" are displayed. By displaying the information about the transfer floor on the first assigned car in motion, it is possible to inform the user who is on board of the transfer floor again, and also to announce that the transfer car will be guided before the arrival of the transfer car. be able to. In this way, user convenience can be improved. If the transfer floors are different depending on the destination floors even in the same car, the in-car display 400 may display each destination floor and the transfer floor corresponding to each destination floor together.

The group supervisory control device 100 determines whether or not the first assigned car has departed (S16). When the control unit 101 of the group supervisory control device 100 receives a signal indicating that the first assigned car has departed from the car controllers 220 and 320 corresponding to the first assigned car, it determines that the first assigned car has departed. .

When determining that the first assigned car has not departed (NO in S16), the group supervisory control device 100 executes step S16 again.

When determining that the first assigned car has departed (YES in S16), the group supervisory control device 100 calculates the "remaining time" until the first assigned car arrives at the transfer floor (S17). The control unit 101 of the group supervisory control device 100 selects the first assigned car based on the current position of the first assigned car, the number of floors to the transfer floor, the calls registered at the floors on the way to the transfer floor, etc. Calculate the remaining time until reaches the transfer floor. Any known method may be used to calculate the remaining time.

The group supervisory control device 100 determines whether or not the remaining time calculated in step S17 is within a predetermined time (S18). The predetermined time is, for example, 10 seconds. If it is determined that the remaining time is not within the predetermined time (NO in S18), steps S17 and S18 are executed again.

When determining that the remaining time is within the predetermined time (YES in S18), the group supervisory control device 100 determines the second assigned car (S19). The second assigned elevator is the next elevator 330 used by the user to move to the destination floor after getting off at the transfer floor. The second assigned elevator is an elevator in a different bank than the first assigned elevator. The second assigned car is also called a "transfer car".

The determination of the second assigned car (S19) may be performed in the same manner as the determination of the assigned car in step S12. That is, the control unit 101 of the group supervisory control device 100 obtains an allocation evaluation value for each car, assigns a destination floor call to the car having an allocation evaluation value indicating the optimum allocation among the obtained allocation evaluation values, and selects the car. The second assigned car may be determined. This assigned evaluation value is an evaluation regarding the operation of elevator 330, and is also referred to as a "second evaluation".

When the second assigned elevator car is determined (S19), the group supervisory control device 100 transmits a second assignment result signal to the lower bank elevator elevator controller 220 and the upper bank elevator elevator controller 320 (S20). In the case of movement from a low-level bank to a high-level bank, a second allocation result signal is transmitted to the low-level bank machine controller 220 corresponding to the first allocated machine and the high-level bank machine controller 320 corresponding to the second allocated machine. do. In the case of movement from a high-rise bank to a low-rise bank, the second allocation result is transmitted to the high-rise bank elevator car control device 320 corresponding to the first allocated car and the low-rise bank elevator car control device 220 corresponding to the second allocated car. . The second allocation result signal includes information about the second allocated car determined in step S19.

Of the car control devices 220 and 320 that have received the second allocation result signal from the group supervisory control device 100, the car control device corresponding to the first allocated car that is running displays the in-car display of the first allocated car. Display guidance information about the number. Examples of the display are shown in FIGS. 14 and 15. FIG.

FIG. 14 is a diagram showing a display example of the in-car indicator 400 according to the first embodiment. Upon receiving the second allocation result signal, the in-car display 400 is controlled to switch from the display screen of FIG. 13 to the display screen of FIG. The in-car display device 400 shown in FIG. 14 displays the characters "transfer guidance", the characters "15th floor→Car H", and the characters "18th floor→Car I". As a result, users boarding the first allocated elevator can recognize the destination floor and transfer elevator information in advance before arriving at the transfer floor, and can transfer to the transfer elevator after getting off at the transfer floor. can be done smoothly.

FIG. 15 is a diagram showing a display example of the in-car indicator 400 according to the modification of the first embodiment. In the example shown in FIG. 15, in addition to the display contents of FIG. 14, the characters "(Transfer at the 10th floor)" are displayed in the lower row. User convenience can be improved by displaying the information on the "transfer floor" in addition to the information on the "transfer car".

On the other hand, among the elevator car controllers 220 and 320 that have received the second assignment result signal from the group supervisory control device 100, the elevator controller corresponding to the second assigned elevator car opens the door for a predetermined time when the second assigned elevator car arrives. control to open.

FIG. 16 is a schematic diagram showing the operation of transferring to a transfer car after the user arrives at the transfer floor. In the example shown in FIG. 16, user X1 who was on board E car (first allocated car) of the low-rise bank transfers to I car (second allocated car) of the high-rise bank, and the same E car (first allocated car) A case where user X2, who was on a high-rise bank, transfers to a high-rise bank car No. H (second assigned car) will be exemplified. As shown in FIGS. 14 and 15, since the transfer car is displayed on the in-car display 400 of the first assigned car that is running, a plurality of users X1 and X2 can smoothly transfer to each transfer car. be able to.

In the example shown in FIG. 16, a floor indicator 500 is provided on the wall surface between the low bank and the high bank. The floor display device 500 displays the same display as the display examples shown in FIGS. 14 and 15, and displays guidance regarding transfer elevators. Specifically, the floor display 500 receives the second assignment result signal from the group supervisory control device 100 in the same manner as the elevator controller (S20), and transfers to the second assigned elevator included in the second assignment result signal. Floors may be displayed. At this time, the floor display device 500 may categorize by the first assigned elevator car and display information on the second assigned elevator car and transfer floors. As a result, the user can check the second assigned car to which he/she will transfer next while checking the first assigned car he has boarded. In this way, user convenience may be further improved.

3. According to the elevator system described above, even if a destination floor call for movement between different banks is registered in the destination floor registration devices 210 and 310 (YES in S11), the group supervisory control device 100 registers the first assigned elevator and The transfer floor is determined (S14), and the second assigned car after transfer is also determined (S19). Elevator users can move between different banks only by performing a destination floor registration operation once, and the convenience of the users can be improved.

When transfer floors are determined from among multiple common floors (1st floor, 10th floor), transfer floors are selected based on the combination of common floor and elevator that minimizes the "required time" from the departure floor to the common floor. and the first assigned car is determined (S14). As a result, operation with improved operating performance of the elevator becomes possible. Also, when the second assigned elevator (transfer elevator) is determined from multiple (6) elevators, the remaining time until the first assigned elevator arrives at the transfer floor is within the predetermined time. A transfer car is determined (S17-S19). As a result, the transfer car can be determined based on the latest information immediately before arriving at the transfer floor, and a more appropriate transfer car can be selected.

When the transfer car is determined, the information about the transfer car is displayed on the in-car display 400 of the first assigned car that is running (FIGS. 14 and 15). As a result, the user can recognize the transfer machine before arriving at the transfer floor, and as shown in FIG. you can switch.

(Embodiment 2)
In the second embodiment, regarding the determination processing (S14) of the first assigned car and transfer floor in the flowchart of FIG. 11, steps S14-1 and S14-2 shown in FIG. Execute S100-2.

FIG. 17 is a flowchart showing an example of the first assigned car and transfer floor determination process (S100) according to the second embodiment. In step S14 of the first embodiment, the first assigned car and transfer floor are determined based on the "required time" to arrive at the common floor, whereas in step S100 of the second embodiment, The first assigned car and transfer floor are determined based on the "power consumption" until arrival. Differences from the first embodiment will be mainly described below.

As shown in FIG. 17, the group supervisory control device 100 determines the power consumption until each elevator reaches the first common floor when assigned to the first common floor, and the power consumption when each elevator is assigned to the second common floor. 2, the power consumption until reaching the common floor is calculated (S100-1). For example, when an allocation request signal is received from the destination floor registration device 210 for the low-rise bank, the control unit 101 of the group supervisory control device 100 performs transfer for each of the six low-rise bank elevators 230 (A to F). The power consumption until arrival at the 1st floor when assigned to the 1st floor, which is a floor candidate, and the power consumption until arrival at the 10th floor, when assigned to the 10th floor, which is a transfer floor candidate, are calculated. When receiving an allocation request signal from the high-rise bank destination floor registration device 310, the control unit 101 of the group supervisory control device 100 selects transfer floor candidates for each of the six high-rise bank elevators 330 (G-to-L). and the power consumption until reaching the 10th floor when assigned to the 10th floor, which is a transfer floor candidate. The group supervisory control device 100, for example, calculates the power consumption until each elevator reaches the common floor based on the current position of each elevator and the number of floors to the common floor. Note that when calculating the power consumption, the weight of the passenger who is currently boarding or who is scheduled to board the vehicle and the weight of the counterweight may be taken into consideration. As a result, it becomes possible to determine whether the operation up to the common floor is powered operation or regenerative operation, and it is possible to accurately calculate the power consumption according to the weight of the passengers. Note that the weight of passengers can be estimated based on the number of calls between floors (the number of passengers) grasped by the destination floor registration.

The group supervisory control device 100 determines the first assigned elevator car and transfer floor based on the combination of elevators and common floors that minimize power consumption until arrival (S100-2). The control unit 101 of the group supervisory control device 100 identifies the combination of the elevator car and the common floor that has the lowest power consumption among the plurality of power consumptions calculated in step S100-1, and determines the elevator car and the common floor that constitute the combination. are set to the first assigned car and transfer floor.

According to the above determination method, the power consumption up to the transfer floor can be minimized, and the operating cost of the elevator can be reduced.

(Other embodiments)
(A) In each of the above embodiments, the first assigned car and transfer floor are determined based on either the required time or the power consumption (S14, S100), but this is not the only case. For example, the first assigned car and transfer floor may be determined while properly using the required time and power consumption according to the time period. Specifically, in the first time slot, the first assigned car and transfer floor are determined based on the required time, and in the second time slot different from the first time slot, the first Assigned elevators and transfer floors may be determined. The first time zone is, for example, a busy time such as the time to go to work (8:30 am to 9:00 am) and the time to leave the office (5:00 pm to 6:00 pm), and the second time zone is the other non-crowded time. It is time. By determining the first assigned elevator and transfer floor based on the required time during times when the elevator is used frequently, it is possible to improve user convenience, while during times when the elevator is used less frequently, it is based on power consumption. , it is possible to operate in such a way as to reduce operating costs.

(B) In the first embodiment described above, regarding step S14 relating to the process of determining the first assigned car and the transfer floor, a case was described in which the determination is made based on the time required to arrive at the common floor from the departure floor. not limited to For example, the first assigned car and transfer floor may be determined based on the total required time from the departure floor to the destination floor. The required time from the departure floor to the destination floor is calculated by (1) calculating the required time from the departure floor to the common floor by the same method as in Embodiment 1, and (2) storing the required time from the common floor to the destination floor. It may be calculated by reading from 102 and adding. In this case, (2) the required time from the common floor to the destination floor is defined in advance as a constant for each combination of common floors and non-common floors. The group supervisory control device 100 uses the required time stored in the storage unit 102 as (2) the required time from the common floor to the destination floor, thereby simplifying the total required time from the departure floor to the destination floor. can be calculated in the following manner.

(C) In each of the above embodiments, the case where the group supervisory control device 100 is one control device has been described, but the present invention is not limited to such a case. For example, as shown in FIG. 18, a group supervisory control system 1000 comprising a plurality of devices may be used.

When the destination floors registered by the destination floor registration device 210 for the low-rise bank are the floors of the low-rise bank (1st to 10th floors) (NO in S11 of FIG. 11), the input transfer device 1100 outputs the call signal of the destination floor. is transferred only to the group management controller 1200 for the low bank. The group supervisory control device 1200, which has received the call signal for the destination floor, determines the assigned car from among the elevators 230 of A to F based on the assigned evaluation value, which is an index related to transportation performance, for example (S12). . The group supervisory control device 1200 transmits an allocation result signal including information on the determined allocated car to the car control device 220 corresponding to the allocated car, and also to the destination floor registration device 210 via the input transfer device 1100. (S13).

When the destination floors registered by the destination floor registration device 310 for high-rise banks are high-rise bank floors (1st floor, 10th to 20th floors) (NO in S11), the input transfer device 1100 outputs a call signal for the destination floor. is transferred only to the high-rise bank group management controller 1300 . The group supervisory control device 1300, which has received the call signal for the destination floor, determines the elevator car to be assigned from among the G-to-L elevators 330 based on the assigned evaluation value, which is an index related to transportation performance, for example (S12). . The group supervisory control device 1300 transmits an allocation result signal including information on the determined allocated car to the car control device 320 corresponding to the allocated car, and also to the destination floor registration device 310 via the input transfer device 1100. (S13).

On the other hand, if the departure floor and the destination floor included in the allocation request signal received from the destination floor registration devices 210 and 310 are floors of different banks (YES in S11), the input transfer device 1100 performs group management control for low-rise banks. The destination floor call signal is transferred to both the device 1200 and the high-rise bank group supervisory control device 1300 .

Of the group management controllers 1200 and 1300 that have received the call signal for the destination floor, the process of determining the first assigned elevator and the transfer floor (S14) is the group management control on the bank side that manages the elevators from the departure floor to the transfer floor. It may be performed by the device alone. In the process of determining the second assigned car (S19), based on information transmitted from the low-rise bank group management control device 1200 and information transmitted from the high-rise bank group management control device 1300, the input transfer device 1100 may be executed. At this time, the input transfer device 1100 acquires information (S17) on the remaining time until the first assigned elevator arrives at the transfer floor from the bank-side group supervisory control device that manages the elevators from the departure floor to the transfer floor. Alternatively, information such as the arrival time until each elevator of the bank reaches the transfer floor may be obtained from the bank-side group supervisory control device that manages the elevators from the transfer floor to the destination floor.

According to the above configuration, it is possible to execute the same processing as in the first and second embodiments while communicating necessary information between the devices in the group supervisory control system 1000 .

(D) In each of the above-described embodiments, the case where there are two common floors (1st floor and 10th floor) for the low-rise bank and the high-rise bank has been described, but this is not the only case, and there are three or more common floors. may exist.
