Elevator system

This application is based on and claims the benefit of priority from Japanese Patent Application No. 2016-000071 (filing date: January 4, 2016), the entire contents of which are incorporated herein by reference.

Technical Field

Embodiments of the present invention relate to an elevator system.

Background Art

Conventionally, a technology is known that automatically assigns a single elevator to a predetermined destination floor (the intended floor) to a user who has passed through a security gate and received authentication. With this technology, a user may miss the elevator automatically assigned to them. In this case, the user must request an elevator assignment for the predetermined destination floor again.

Summary of the Invention

In existing elevator systems, to receive an elevator reassignment, users must return to the emergency door and operate a dedicated destination floor registration device located in the elevator lobby for receiving an elevator reassignment. Therefore, it is desirable to further improve user convenience when receiving an elevator reassignment.

The elevator system of the embodiment is an elevator system that manages a plurality of elevators installed in a building equipped with a security door as a group. The elevator system includes an authentication device and a control device. The authentication device authenticates a user who enters the building through the security door (entry). Based on the authentication result of the authentication device, the control device allocates a first elevator bound for a first destination floor from among the plurality of elevators to the user, and when predetermined conditions related to the first elevator are met, the control device causes the first elevator to depart for the first destination floor. Each of the plurality of elevators includes a car, a registration device, and a first notification device. The registration device is provided in the car and is configured to receive registration of a destination floor by a user in the car. The first notification device is provided in the car and is configured to notify information. After the first elevator is started, if the registration device of one of the plurality of second elevators other than the first elevator accepts a registration for the first destination floor from a user who missed boarding the first elevator, the control device allocates a third elevator heading for the first destination floor from among the plurality of second elevators to the user who missed boarding the first elevator, and causes the first notification device of the one elevator to notify the user of guidance to the third elevator.

According to the elevator system having the above configuration, it is possible to further improve the convenience for users when receiving an elevator assignment again.

DETAILED DESCRIPTION

<Implementation Method>

First, the configuration of an elevator system 1 according to the embodiment will be described with reference to FIG. 1 to FIG. 4 .

FIG1 is a block diagram illustrating an exemplary configuration of an elevator system 1 according to an embodiment. As shown in FIG1 , the elevator system 1 according to the embodiment includes a control device 50 that manages an elevator group 3 comprising four elevators 4, namely, elevators A through D, as a group. This control device 50 includes four individual control devices 9 that control each of the four elevators 4 as an individual, and a single group management control device 2 that controls the four elevator groups 3 as a group. While FIG1 illustrates an example of an elevator group 3 comprising four elevators 4, in the embodiment, the number of elevators 4 constituting the elevator group 3 may be three or fewer, or five or more.

Each elevator 4 includes a car 5, a counterweight 6, a main rope 7, and a hoisting machine 8. Each elevator 4 is a so-called bucket elevator, in which the car 5, which can be raised and lowered within a hoistway installed in a building, and the counterweight 6, which serves as a counterweight, are connected by the main rope 7. The main rope 7 is suspended from, for example, a main pulley 8a and a guide pulley (not shown) of the hoisting machine 8 located above the hoistway. One end of the main rope is connected to the car 5, and the other end is connected to the counterweight 6. The hoisting machine 8 also includes, for example, a power-generating electric motor 8b. This motor 8b drives the main pulley 8a connected to the motor 8b, which is then rotated. The friction generated between the main pulley 8a and the main rope 7 electrically pulls the main rope 7. Each elevator 4 is controlled by a corresponding individual control device 9. This allows the car 5 to ascend and descend within the hoistway, allowing users to travel to a boarding hall 10 of a desired floor by riding the car 5.

The individual control device 9 includes a microcomputer and a drive circuit. The microcomputer includes, for example, a CPU (Central Processing Unit) that performs various calculations, a ROM (Read Only Memory) that pre-stores predetermined control programs, a RAM (Random Access Memory) that temporarily stores CPU calculation results, a backup RAM that stores pre-prepared mapping data and information such as the specifications of the elevator 4, and input/output port devices. Furthermore, the various components of the microcomputer are interconnected via a conventional bidirectional common bus. The individual control device 9 is electrically connected to the various components of the elevator 4, including the hoisting machine 8, and comprehensively controls the operation of the elevator 4.

Like the individual control devices 9 described above, the group management control device 2 also includes a microcomputer and a drive circuit. The microcomputer includes, for example, a CPU (Central Processing Unit) that performs various calculations, a ROM (Read Only Memory) that pre-stores predetermined control programs, a RAM (Random Access Memory) that temporarily stores CPU calculation results, a backup RAM that stores pre-prepared mapping data and information such as elevator 4 specifications, and input/output port devices. Furthermore, the various components of the microcomputer are interconnected via a conventional bidirectional common bus. The group management control device 2 performs group management of the elevator group 3 by exchanging detection signals, drive signals, control commands, and the like with the individual control devices 9 of the multiple elevators 4.

In this embodiment, a security door 220 is installed at a location (e.g., an entrance of a building using the elevator system 1) leading to the lobby 10 of the elevator 4. The security door 220 is connected to an authentication device 210 that authenticates users entering the building through the security door 220.

Fig. 2 is an illustrative diagram showing the appearance of a security door 220 according to an embodiment. Hereinafter, as an example, an example in which the authentication device 210 is incorporated into the security door 220 will be described.

As shown in Figure 2, security door 220 is a so-called flapper gate with an openable and closable door leaf 221. It includes an authentication device 210, a reader 222, and a door-side notification device 223. Reader 222 is configured to read predetermined identification information from an ID card 19 carried by a user entering the building through security door 220 (a person using elevator 4) using either a contact or non-contact method. Furthermore, door-side notification device 223 is an output device such as a display device or a speaker that can notify users about information before they pass through security door 220.

The reader 222 is provided so as to be exposed from the security gate 220. Thus, when a user passes through the security gate 220, they can bring their ID card 19 into contact with or close to the reader 222, allowing the reader 222 to read the identification information embedded in the ID card 19. The ID card 19 has a built-in RFID (Radio Frequency Identification) tag or the like embedded with the identification information.

Furthermore, the embodiments are not limited to a configuration in which identification information is read from an ID card 19. Alternatively, the identification information may be read from a file containing a two-dimensional code, such as a QR code (registered trademark) or a barcode. For example, a situation in which company staff within a building pre-issue a notice (invitation) containing a QR code to users entering the building can be envisioned. In this case, the identification information corresponding to the QR code on the notice is associated with the destination tier of the user to whom the notice was issued, and the information is then registered in a storage unit (not shown).

The aforementioned identification information is the subject of authentication processing by authentication device 210. Based on the identification information read by reader 222, authentication device 210 determines whether the user attempting to pass through security gate 220 has been granted entry in advance by, for example, a company employee within the building. If it is determined that the user attempting to pass through security gate 220 has been granted entry in advance by, for example, a company employee within the building, door leaf 221 of security gate 220 opens, allowing passage through.

In the embodiment, the destination floor that the user can reach by riding the elevator 4 (car 5) is preset based on the user (identification information). In other words, the group management control device 2 of the embodiment is configured to allocate one elevator 4 from a plurality of elevators 4 to the destination floor preset based on the user's identification information, based on the authentication result of the authentication device 210.

More specifically, when the authentication device 210 completes authentication processing and determines that the user about to pass through the security door 220 is a person who has been granted entry permission in advance, the group management control device 2 dispatches one of the multiple elevators 4 to the lobby 10 and performs a call registration process to register the destination floor preset by the user with the elevator 4. The group management control device 2 determines the elevator 4 to be dispatched to the lobby 10 based on the status of each car 5 of each elevator 4.

For example, the group control device 2 performs a predetermined evaluation calculation for calls generated by the elevator group 3 based on the total number of calls (total number of users) and/or the number of calls to each destination floor, outputs from various sensors and detectors, the current position and movement direction (up/down direction) of the car 5, predicted hall calls and car calls, and the predicted destination floor, among other conditions of each elevator 4 and car 5. Furthermore, based on this predetermined evaluation calculation, the group control device 2 determines the arrival order of the cars 5, etc., so that each car 5 moves optimally while responding to each call, and performs allocation processing to allocate the car 5 to respond to each call. In this way, the group control device 2 efficiently allocates the operation of multiple cars 5, thereby ensuring efficient operation of the elevator group 3 as a whole.

Here, the group management control device 2 causes the door-side notification device 223 of the security door 220 to display guidance to the elevator 4 assigned through the call registration process described above. For example, the group management control device 2 causes the door-side notification device 223 to display the identification information (name, number, etc.) of the elevator 4 assigned through the call registration process, or causes the door-side notification device 223 to display the location of the elevator within the lobby 10 and a map of the lobby 10. This allows users to easily confirm the route of the elevator 4 they are supposed to board (the elevator 4 automatically assigned by the group management control device 2) by checking the door-side notification device 223 when passing through the security door 220.

When a predetermined condition related to an elevator 4 is met, the group management control device 2 of the embodiment automatically causes the elevator 4 to depart. The predetermined condition refers to the number of times the elevator 4 has been assigned by the group management control device 2 (allocation count) reaching a predetermined value. The predetermined value corresponds to the upper limit of the number of people that can board the car 5 of the elevator 4. Each time the group management control device 2 assigns an elevator 4 to a user, it increments the allocation count for that elevator 4. Furthermore, the group management control device 2 counts the allocation count for each of the multiple elevators 4, excludes elevators 4 whose allocation counts have reached the predetermined value from the aforementioned allocation targets, and then causes the elevators 4 to wait for a predetermined time before departing to the destination floor. The predetermined time, for example, is sufficient time for a user who has passed through the security door 220 to board the elevator 4.

The automatic departure of the elevator 4 described above is performed regardless of whether the user has boarded the elevator 4. That is, in this embodiment, even if a user who has passed through the security door 220 does not board the elevator 4 automatically assigned by the group control device 2, the group control device 2 will determine that the departure conditions have been met and automatically dispatch the elevator 4 if the number of assigned times for that elevator 4 reaches a predetermined value. Therefore, if a user becomes disoriented or otherwise attends to other matters after passing through the security door 220, they may not be able to board the assigned elevator 4 within the predetermined time. In such cases, the user will need to be reassigned another elevator 4 to the destination floor, replacing the elevator 4 they missed.

Conventionally, in order to receive the reassignment of the elevator 4, the user had to return to the security door 220 and operate a dedicated destination floor registration device, etc., provided in the elevator 4 lobby 10, etc., for receiving the reassignment of the elevator 4. Therefore, it is desired to further improve the convenience of the user when receiving the reassignment of the elevator 4.

Therefore, in the embodiment, it is configured so that the user can receive the allocation of the elevator 4 again by operating the operating panel 18 provided as a normal device in the car 5. As a result, the user who missed the elevator 4 allocated when passing through the safety door 220 can receive the allocation of the elevator 4 again by simply getting on the car 5 of another elevator 4 waiting in the boarding and alighting hall 10 and performing a predetermined operation using the operating panel 18 in the car 5.

FIG3 is an illustrative diagram showing the equipment within the car 5 according to the embodiment. As shown in FIG3 , an operating panel 18 and a car-side notification device 14 are provided within the car 5. The operating panel 18 is a destination floor registration device, such as a button, configured to receive registration of a destination floor by a user riding in the car 5. The car-side notification device 14 is an output device, such as a display device and a speaker, capable of notifying users riding in the car 5 of information.

If a user misses the elevator 4 that was automatically assigned when passing through the security door 220, they board the car 5 of another elevator 4 that arrives at the lobby 10 and operate the operating panel 18 inside that car 5 to input their destination floor. In this embodiment, since the destination floor is set for each elevator 4 when the group control device 2 assigns the elevator 4, even if the user enters the destination floor by entering the other elevator 4, the other elevator 4 may not stop at the input destination floor. Therefore, when the operating panel 18 accepts the destination floor input by a user who missed the elevator 4, the group control device 2 executes a re-call registration process. This process is to re-assign an elevator 4 heading for the input destination floor to the user from among multiple elevators 4 other than the elevator 4 that the user missed (including the other elevator 4 for which the destination floor was input).

The group management control device 2 causes the car-side notification device 14 in the car 5 in which the user, who has received the new assignment of the elevator 4 through the re-call registration process, is currently riding to notify the user of guidance to the newly assigned elevator 4. For example, if the car 5 in which the user is currently riding matches the car 5 of the newly assigned elevator 4, the group management control device 2 causes the car-side notification device 14 in the car 5 in which the user is currently riding to notify the user of a message urging the user to wait in the car 5 in which the user is currently riding. Alternatively, if the car 5 in which the user is currently riding does not match the car 5 of the newly assigned elevator 4, the group management control device 2 causes the car-side notification device 14 in the car 5 in which the user is currently riding to notify the user of a message urging the user to transfer to the car 5 of the newly assigned elevator 4.

The transfer guidance described above is achieved by causing the car-side notification device 14 to display the identification information of the elevator 4 at the transfer destination, or by displaying the position of the elevator 4 in the hall 10 and a map of the hall 10. Thus, the user can easily confirm the movement of the other elevator 4 they are about to board by checking the car-side notification device 14 in the car 5 for which the destination floor is registered.

Here, in the embodiment, guidance to the elevator 4 of the transfer destination is not only notified by the car-side notification device 14 in the car 5 in which the user is riding, but can also be notified by equipment in the boarding hall 10 as will be described below.

FIG4 is an illustrative diagram showing the equipment within the hall 10 according to the embodiment. As shown in FIG4 , the hall 10 is provided with a hall-side notification device 12 and a car position floor indicator 13. The hall-side notification device 12 is, for example, an indicator such as a lantern that allows users to identify the elevator 4. Furthermore, the car position floor indicator 13 is configured to indicate which floor the corresponding car 5 is currently located. A plurality of these hall-side notification devices 12 and car position floor indicators 13 are provided, each corresponding to a plurality of elevators 4.

When a user needs to transfer to a car 5 through a re-call registration process, the group management control device 2 of the embodiment displays guidance to the transfer destination elevator 4 on the car-side notification device 14 in the car 5 and illuminates the hall-side notification device 12 corresponding to the transfer destination elevator 4 in a manner that allows the user to distinguish it from the other hall-side notification devices 12. This allows the user to obtain information about the transfer destination elevator 4 even after exiting the car 5 and moving through the hall 10. Furthermore, the hall-side notification device 12 can be used not only to provide guidance to the car assigned through the re-call registration process but also to provide guidance to the car assigned through the call registration process.

Furthermore, in the embodiments, the call registration process and the re-call registration process may be performed simultaneously, and the same elevator (elevator 4) may be assigned by both processes. In this case, if the number of times the same elevator is assigned does not reach the predetermined value even after both the call registration process and the re-call registration process, no problem will arise. However, if the number of times the same elevator is assigned reaches the predetermined value after either the call registration process or the re-call registration process, it will be more efficient to predetermine whether the same elevator will be assigned first: to a user assigned by the call registration process (a user inside the safety door 220) or to a user assigned by the re-call registration process (a user already in the car 5).

Therefore, in the embodiment, when the above-described situation occurs, the group control device 2 prioritizes users already in the car 5. More specifically, when the above-described situation occurs, the group control device 2 causes the car 220 to depart before the user inside the safety gate 220 has completely passed through the safety gate 220, that is, before the user enters the car automatically assigned by the call registration process (the same car described above). Furthermore, the group control device 2 assigns the user inside the safety gate 220 a new car different from the car the user missed (the same car described above), and causes the door-side notification device 223 to notify the user of the newly assigned car. This allows users already in the car 5 to arrive at their destination floor with priority, while also allowing users inside the safety gate 220 to reach their destination floor via a car different from the one they were initially assigned.

Next, control executed in the elevator system 1 according to the embodiment will be described.

FIG5 is an exemplary flowchart showing the flow of processing executed by the elevator system according to the embodiment.

In the process flow of FIG5 , first, in S1, the authentication device 210 performs authentication processing on a user who is about to pass through the security gate 220. As described above, the authentication process is the process of determining whether to grant permission to the user to pass through the security gate 220. The specific processing performed in S1 will be described later using FIG6 , and therefore will be omitted here.

In S2, the group control device 2 performs call registration based on the results of the authentication process in S1. As described above, call registration involves assigning a user authenticated by the authentication device 210 to an elevator 4 (machine) destined for a destination floor pre-set based on the user's identification information. The specific processing performed in S2 will be explained later using Figure 7 and will therefore be omitted here.

In S3, the group control device 2 determines whether the departure condition of elevator 4 (machine number) is satisfied. The departure condition of elevator 4 is that the number of times that elevator 4 has been assigned by the above-mentioned call registration process and re-call registration process (number of assignments) has reached a predetermined value.

If it is determined in S3 that the departure condition is satisfied, the process proceeds to S4. Then, in S4, the group control device 2 starts the car that satisfies the departure condition. Then, the process ends.

If it is determined in S3 that the start condition is not satisfied, the process of S4 is not executed and the process is terminated directly.

FIG. 6 is an exemplary flowchart showing the authentication process (processing executed in S1 of FIG. 5 ) according to the embodiment.

6 , first, in S11, the authentication device 210 reads identification information from the ID card 19 that is in contact with or close to the reader 222 of the security door 220. At this time, the door 221 of the security door 220 is closed.

In S12, the authentication device 210 determines whether the user of the ID card 19 corresponding to the identification information is a person who has been given entry permission in advance by company employees in the building, that is, whether the user can be given permission to pass through the security gate 220 based on the identification information read in S11.

If it is determined in S12 that the user can be allowed to pass through the security door 220, the process proceeds to S13. Then, in S13, the authentication device 210 opens the door 221 of the security door 220. The process then returns to S2 in FIG. 5 .

On the other hand, if it is determined in S12 that the security door 220 cannot be passed, the process proceeds to S14. In S14, the authentication device 210 keeps the door 221 of the security door 220 closed. The process then returns to S2 in FIG. 5 .

FIG. 7 is a flowchart showing an example of the call registration process (processing executed in S2 of FIG. 5 ) according to the embodiment.

In the processing flow of Figure 7 , first, in S21, the group control device 2 assigns one elevator (elevator 4) to a user authenticated by the authentication device 210. Specifically, based on the authentication result of the authentication device 210, the group control device 2 assigns one elevator 4 from a plurality of elevators 4 to the authenticated user.

In S22, the group management control device 2 causes the door-side notification device 223 of the security gate 220 to notify the driver of the vehicle assigned in S21. For example, the group management control device 2 causes the door-side notification device 223 to display the identification information of the vehicle assigned in S21, or causes the door-side notification device 223 to display the location of the vehicle within the lobby 10 and a map of the lobby 10.

In S23, the group control device 2 registers the destination floor to the elevator assigned in S21. The destination floor registered here is a destination floor that is set in advance for the user and that the user can reach by riding the elevator 4 (car 5).

In S24, the group control device 2 increments the count of the number of times the car assigned in S21 is assigned. Then, the process returns to S3 of FIG5.

Fig. 8 is a flowchart illustrating an example of the re-call registration process according to the embodiment. As described above, the re-call registration process is a process for assigning another car to a user who has missed the car (elevator 4) assigned by the call registration process (see Fig. 7 ).

In the processing flow of FIG8 , first, in S31, the group management control device 2 determines whether the operating panel 18 in the car 5 has accepted the input of the destination floor by the user. If it is determined in S31 that the operating panel 18 has not accepted the input of the destination floor, the processing ends. On the other hand, if it is determined in S31 that the operating panel 18 has accepted the input of the destination floor, the processing proceeds to S32.

In S32, the group control device 2 newly allocates to the user a car that goes to the destination floor input in S31 from cars other than the car that the user missed taking.

In S33, the group management control device 2 determines whether the car 5 having the operating panel 18 for which the input of the destination floor was received in S31 (i.e., the car 5 in which the user who inputted the destination floor is currently riding) is the same as the car 5 of the elevator 4 newly assigned in S32. In other words, the group management control device 2 determines whether the destination floor input in S31 has already been registered as the stopping floor of the car 5 in which the user who inputted the destination floor is currently riding.

In S33, if the destination floor input in S31 has already been registered as a stop floor, the process proceeds to S34. In this case, the user can reach the destination floor without changing cars 5. Therefore, in S34, the group management control device 2 causes the car-side notification device 14 in the car 5 the user is currently riding to notify that no transfer is necessary. Then, in S35, the group management control device 2 increments the count of the number of times the car corresponding to the car 5 the user is currently riding is assigned. The process then terminates.

On the other hand, in S33, if the destination floor input in S31 has not been registered as a stop floor, the process proceeds to S36. In this case, since the user cannot reach the destination floor even if they remain in the car 5 they are currently riding, they need to transfer to another car 5 (machine). Therefore, in S36, the group management control device 2 causes the car-side notification device 14 in the car 5 the user is currently riding in and the hall-side notification device 12 in the hall 10 outside the car 5 to notify the user of guidance to the machine of the transfer destination. Then, in S37, the group management control device 2 increments the count of the number of times the machine corresponding to the car 5 of the transfer destination is allocated. Then, the process ends.

FIG. 9 is a flowchart showing an example of processing when a conflict occurs between the call registration processing (see FIG. 7 ) and the re-call registration processing (see FIG. 8 ) in the embodiment.

In the processing flow of Figure 9, first, in S41, the group management control device 2 determines whether the elevator call registration processing and the re-call registration processing are performed simultaneously, and through these two processes, the same machine (elevator 4) is assigned to the user who passes through the safety door 220 and the user who operates the operating panel 18 in the car 5.

If it is determined in S41 that the call registration process and the re-call registration process are not being performed simultaneously, or that the same elevator number is not assigned by these two processes, the process ends. On the other hand, if it is determined in S41 that the call registration process and the re-call registration process are being performed simultaneously and the same elevator number is assigned by these two processes, the process proceeds to S42.

In S42, the group control device 2 increments the count of the number of allocations. Specifically, the group control device 2 increments the count of the number of allocations to the same elevator by two times, one by the call registration process and one by the re-call registration process.

In S43, the group control unit 2 determines whether the number of times the same elevator has been assigned has reached a predetermined value through either the call registration process or the re-call registration process. If it is determined in S43 that the number of times assigned has not reached the predetermined value, the process ends. On the other hand, if it is determined in S43 that the number of times assigned has reached the predetermined value, the process proceeds to S44.

In S44, the group control unit 2 causes the same car to depart. More specifically, the group control unit 2 causes the car to depart before the user inside the security gate 220 has completely passed through the security gate 220, that is, before the user has boarded the car automatically assigned by the call registration process (the same car). In this case, the user inside the security gate 220 will miss the car automatically assigned by the call registration process.

Therefore, in S45, the group control device 2 newly assigns a car (elevator 4) different from the car that the user missed to the safety gate 220. Then, in S46, the group control device 2 causes the door-side notification device 223 of the safety gate 220 to display guidance to the car newly assigned in S45.

Then, in S47, the group control unit 2 registers the destination floor pre-set based on the user's identification information with the newly assigned elevator in S45. Then, in S48, the group control unit 2 increments the count of the number of times the newly assigned elevator in S45 has been assigned. The process then ends.

As described above, the control device 50 (group management control device 2) of the embodiment causes the car (elevator 4) assigned to a user inside the safety gate 220 to depart. If the operating panel 18 in one of the multiple other cars other than the assigned car receives a destination floor registration from a user who missed boarding the assigned car, the control device 50 then assigns a new car to the user's destination floor from the multiple other cars, and causes the car-side notification device 14 in the car 5 equipped with the operating panel 18 that received the destination floor registration to notify guidance to the newly assigned car. Thus, even if the user missed boarding the car assigned inside the safety gate 220, simply by boarding the car 5 of the other car that has arrived at the hall 10 and performing a predetermined operation, the user can receive a new car assignment to the destination floor in the assigned car 5 and confirm guidance to the newly assigned car. Consequently, user convenience when receiving a new car assignment can be further improved. Furthermore, according to the embodiment, since it is not necessary to provide a dedicated device in the boarding hall 10 only for receiving the allocation of the elevator 4 again, the aesthetics of the boarding hall 10 can also be improved.

Modifications

In the above embodiment, an example has been described in which one elevator (elevator 4) is assigned to a user inside the safety gate 220. However, as a modification, a case where a plurality of elevators are assigned to a user inside the safety gate 220 is also conceivable. This modification will be described below with reference to FIG10 .

Fig. 10 is an exemplary flowchart showing details of the call registration process of a modification. The process flow of Fig. 10 is a process flow executed after the authentication device 210 completes authentication, and corresponds to the processes of S2 to S4 of Fig. 5 in the above-described embodiment.

In the processing flow of Figure 10, first, in S51, the group management control device 2 assigns multiple elevators to the user who has been authenticated by the authentication device 210. In other words, in S51, the group management control device 2 selects multiple elevator candidates that can serve as the elevator that carries the user through the security gate 220 to the destination floor.

Then, in S52, the group management control device 2 causes the door-side notification device 223 of the safety door 220 to notify the passengers of the guidance to the multiple cars assigned in S51. The notification method may be a method of notifying the passengers of the multiple cars at once or a method of notifying the passengers of the multiple cars one by one in sequence.

In S53, the group control device 2 registers the destination floor with the car scheduled to depart earliest among the plurality of cars assigned in S51. Then, in S54, the group control device 2 increments the count of the number of times the car scheduled to depart earliest is assigned.

In S55, the group management control device 2 determines whether the number of times the car scheduled to depart the earliest has been assigned has reached a predetermined value. This S55 process is repeated until it is determined that the number of times the car has been assigned has reached the predetermined value. If it is determined that the number of times the car has been assigned has reached the predetermined value in S55, the process proceeds to S56.

In S56, the group control device 2 starts the car that is scheduled to start the earliest. If a sensor is installed in the car 5 of the car, the sensor can be used to confirm whether the user who has been authenticated by the authentication device 210 has boarded the car 5 before the car is started.

In S57, the group management control device 2 determines whether all of the multiple cars assigned in S51 have departed. If it is determined in S57 that none of the multiple cars have departed, there are still candidates for cars that can carry the user inside the security gate 220 to the destination floor, so the process returns to S53. On the other hand, if it is determined in S57 that all of the multiple cars have departed, it is assumed that the user, authenticated by the authentication device 210, has arrived at the destination floor via one of the multiple cars, and the process ends.
