Detailed Description

Examples of embodiments of the present invention will be described below with reference to the drawings. In the drawings, components having substantially the same function or configuration are denoted by the same reference numerals, and redundant description thereof is omitted. The drawings illustrate specific embodiments and examples consistent with the principles of the present invention, but are for the understanding of the present invention only and are not intended to be limiting of the invention.

< one embodiment >

[ landing layout ]

First, a landing layout of an entrance linkage system of an elevator to which an embodiment is applied will be described with reference to fig. 1. Fig. 1 is a plan view showing a structural example of a landing layout to which an entrance linkage system of an elevator according to an embodiment is applied.

In a landing to which the doorway linkage system of an elevator according to the present embodiment is applied, a plurality of groups a to C configured as groups (groups) divided for each service zone of the car are provided. A plurality of doorway devices 20 are provided on the way to the landings. The doorway device 20 is provided between, for example, an entrance of a building and a landing of each bank of an elevator.

The information medium 10 is one of communication devices, for example, an IC card using a noncontact type. When the user requests to use any floor of the elevator, destination floor information 12 is written in the memory of the information medium 10 by a person in charge of reception of the building in which the elevator is located (see fig. 3 described later). The user of the elevator receives the information medium 10 in which the destination floor information 12 (hereinafter, also simply referred to as "destination floor information") is written from the reception person in charge.

A user who holds the information medium 10 authenticates using the information medium 10 at any one of the gateway devices 20, and enters the elevator hall through the gateway device 20. At this time, the user is guided to one of the group a composed of the individual machines (elevator individual machines) a to D, the group B composed of the individual machines E to H, and the group C composed of the individual machines I to L among the plurality of groups a to C based on the display on the gateway device 20. The "stand-alone" is usually referred to as a car. In this embodiment, bank a is used for the low floor, bank B is used for the medium floor, and bank C is used for the high floor. The information medium 10 and the gateway device 20 will be described in detail with reference to fig. 3 described later.

[ car stop floors assigned to respective banks ]

Fig. 2 is an explanatory diagram showing an example of car stop floors assigned to banks a to C in the entrance/exit linkage system of an elevator according to one embodiment.

In the example of fig. 2, floors from 1 floor (1FL) to 13 floors (13FL), and 1 floor and 2 to 6 floors as reference floors are allocated as stop floors of the bank a. Layers 1 and 6 to 10 are assigned as stop layers for bank B, and layers 1 and 10 to 13 are assigned as stop layers for bank C. The other layers are set as non-stop layers. Here, the floors 1, 6, and 10 are stop floors of a plurality of banks (cars), that is, common floors of banks in which a plurality of banks can receive common service.

The user of the floor set as the common floor of the banks is assigned to one of the banks corresponding to the common floor of the banks differently from the users of the other floors, and therefore is not always assigned to the single machine of the same bank. For example, in the case where the destination floor of the user is the 10 floors that are the common floor, the user is assigned to the individual belonging to the bank a or the bank C, but the assignment to which of the bank a or the bank C is assigned differs depending on the operation state of the individual in each bank at that time.

Therefore, in one embodiment of the present invention, a bank identification ID (an example of bank identification information) for identifying a bank is registered in advance in an information medium 10 held by a user on a bank-sharing floor, and when the user uses an elevator, the bank identification ID registered in the information medium 10 is read by the entrance device 20. Then, based on the bank set in association with the bank identification ID read from the information medium 10, a group management device described later corresponding to the bank is selected, and only the user information including the destination layer information stored in the information medium 10 is transmitted to the group management device.

[ Elevator entrance/exit linkage System ]

Next, a configuration of a control system of an entrance linkage system of an elevator according to an embodiment will be described with reference to fig. 3. Fig. 3 is a block diagram showing an example of a control system configuration of an entrance linkage system of an elevator according to an embodiment.

As shown in fig. 3, the entrance/exit linkage system of an elevator according to the present embodiment includes a plurality of entrance/exit devices 20 through which users having information media 10 pass, a communication switching device 30 that performs communication based on data related to users who pass through the entrance/exit devices 20, group management devices 40A to 40C that perform individual assignment based on data from the communication switching device 30, and individual devices a to L. The elevator entrance/exit linkage system has a multi-bank structure including a bank A, a bank B, and a bank C, wherein the bank A has a group management device 40A (group management device A) for performing group management on a plurality of individual machines A to D, the bank B has a group management device 40B (group management device B) for performing group management on a plurality of individual machines E to H, and the bank C has a group management device 40C (group management device C) for performing group management on a plurality of individual machines I to L.

(gateway device)

The doorway device 20 reads user information from an information medium 10 held by a user to authenticate the user, and transmits the user information to the communication conversion device 30 in order to make a hall call (call) to the floor where the doorway device 20 is located. In the memory mounted on the IC card of the information medium 10, at least the bank identification ID11 (hereinafter, also simply referred to as "bank identification ID") and the destination layer information 12 are stored as user information. The gateway device 20 includes a first communication control unit 21, a security processing unit 22, a display unit 23, and a second communication control unit 24.

The first Communication control unit 21 is a wireless Communication interface for performing wireless Communication with the information medium 10 using a Near Field Communication (NFC) technology. For example, the first communication control unit 21 communicates with the information medium 10 near the reading surface, not shown, of the entrance device 20 by magnetic coupling or the like. The communication data (including the user information) received from the information medium 10 by the first communication control unit 21 is supplied to the security processing unit 22.

The security processing unit 22 authenticates the user based on the user information stored in the information medium 10 supplied from the first communication control unit 21, and opens the door when the authentication is completed. As described above, the read user information includes the destination floor information 12 specified by the user, the bank identification ID11 set based on the destination floor information, and the like. The first communication control unit 21 and the security processing unit 22 constitute a card reader for reading information stored in an IC card or the like.

The display unit 23 displays the results of various processes performed by the security processing unit 22 based on the bank identification ID read from the information medium 10. For example, when the elevator is normal, the display unit 23 performs display processing of the assignment unit data (data indicating which elevator unit is assigned) output from the group management devices 40A to 40C via the second communication control unit 24. In addition, the display unit 23 performs display processing for notifying the abnormality determined by the communication switching device 30 via the second communication control unit 24 when the elevator is abnormal.

The second communication control unit 24 is a communication interface for performing wireless or wired data communication with the communication conversion device 30. For example, the first communication control unit 21 communicates with the information medium 10 near the reading unit, not shown, by magnetic coupling or the like. When transmitting the user information to the communication conversion apparatus 30, the second communication control unit 24 adds the address information of the own apparatus to the user information and transmits the user information. Thus, after the authentication is passed, the target group management apparatus transmits the distributed individual data from the target group management apparatus to the gateway apparatus 20 as the own apparatus using the address information. As the address information, for example, a mac (media Access Control) address, an IP address, or the like can be used.

(communication switching device)

The communication conversion apparatus 30 performs predetermined determination processing based on the user information. The communication converting apparatus 30 includes a first communication control section 31, a bank determining section 32, a communication data converting section 33, and a second communication control section 34.

The first communication control unit 31 performs wired or wireless data communication with each of the gateway devices 20. For example, the first communication control unit 31 receives the user information of the information medium 10 read by the entrance device 20 and supplies the user information to the bank determination unit 32. The first communication control unit 31 transmits the assignment unit data to the corresponding gateway device 20 based on the address information added to the assignment unit data transmitted from the target group management device.

The bank determination unit 32 acquires the bank identification ID read from the information medium 10 held by each user via the first communication control unit 31, and performs a specific process based on the bank identification ID. That is, when the bank identification ID is detected from the user information, the bank determination unit 32 determines the group management device identification ID corresponding to the bank indicated by the bank identification ID with reference to a table T1 shown in fig. 4 to be described later. Then, the bank decision section 32 transmits data including at least user information of the destination layer information to the group management device identified by the group management device identification ID.

The communication data conversion unit 33 performs processing for converting the data supplied from the bank determination unit 32 into a data format for data communication with the group management devices 40A to 40C.

The second communication control unit 34 performs wired or wireless data communication with each of the group management devices 40A to 40C. The second communication control unit 34 selects and communicates with the group management device corresponding to the bank identification ID determined by the bank determination unit 32.

(group management device)

The group management devices 40A to 40C are provided in correspondence with the banks a to C divided for each service section of the car, and select a single machine in the corresponding bank based on the determination result of the communication conversion device 30 to assign a hall call. Since the group management devices 40A to 40C have the same configuration, the group management device 40A will be described here. The group management device 40A includes a communication control unit 41A and a single machine allocation unit 42A.

The communication control unit 41A communicates with the second communication control unit 34 of the communication switching device 30, and communicates with each individual machine (car) in the corresponding bank. For example, the communication control unit 41A acquires the current position of the car of each individual machine, the state of the car, for example, the extension of the door opening time, and the like, and the latest information on the car of each individual machine, for example, the remaining amount of the battery provided in the car.

The unit assigning unit 42A assigns any one of the units a to D in the corresponding bank a by using the data of the user information (destination layer information) received from the communication conversion apparatus 30. The communication control unit 41A communicates with the individual assigned by the individual assigning unit 42A, and moves the car of the individual to the call floor. Then, the communication control unit 41A adds address information of the gateway device 20 to which the user information is transmitted, to the data of the individual (individual distribution data) distributed by the individual distribution unit 42A, and transmits the data to the communication switching device 30.

The group management device 40B includes a communication control unit 41B and a stand-alone distribution unit 42B, and functions thereof are the same as those of the communication control unit 41A and the stand-alone distribution unit 42A of the group management device 40A, respectively. The group management device 40C includes a communication control unit 41C and a single machine allocation unit 42C, and functions thereof are the same as those of the communication control unit 41A and the single machine allocation unit 42A of the group management device 40A, respectively.

Next, an example of the correspondence relationship between the group ID and the group management device in the entrance/exit linkage system of an elevator according to an embodiment will be described with reference to fig. 4. Fig. 4 is an example of an association table showing the association between the group ID and the group management device ID in the entrance/exit linkage system of an elevator according to the embodiment.

In table T1 shown in fig. 4, the group identification ID "AAA" indicating the group a is associated with the group management device identification ID "a". The group management device identification ID "a" indicates a group management device 40A (refer to fig. 3) set in correspondence with the bank a. The bank identification ID "BBB" representing bank B is associated with the group management device identification ID "B". The group management device identification ID "B" indicates a group management device 40B (refer to fig. 3) set in correspondence with the bank B. A bank identification ID "CCC" representing bank C is associated with the group management device identification ID "C". The group management device identification ID "C" indicates a group management device 40C (refer to fig. 3) set in correspondence with the bank C. Each identification ID is represented by letters, but other symbols such as numbers may be used.

The bank determination unit 32 of the communication converting apparatus 30 can refer to the table T1 to specify the group management apparatus corresponding to the bank identification ID read from the information medium 10.

(user information registration device)

The user information registration device 50 shown in fig. 3 performs short-range wireless communication with the information medium 10, and registers destination floor information and the group ID in the user information of the information medium 10. The user information registration device 50 includes a communication control unit 51, a bank identification ID assignment processing unit 52, and a display unit 53.

The communication control unit 51 is a wireless communication interface for performing wireless communication with the information medium 10 using a near field communication technology such as NFC. The data received by the communication control section 51 from the information medium 10 is supplied to the bank identification ID assignment processing section 52.

When the destination floor of the user is a stop floor common to a plurality of banks, the bank ID assignment processing unit 52 calculates the user of each bank corresponding thereto, and registers the bank ID corresponding to the bank having the smallest number of users in the user information of the information medium 10. The registration process of the bank identification ID will be described in detail with reference to fig. 8 described later.

The display unit 53 displays an input setting screen for inputting various information required by the bank ID assignment processing unit 52, assignment results of the bank IDs, and the like.

[ hardware configuration of each device ]

Next, the hardware configuration of each device for realizing the function of the control system of the entrance/exit linkage system of the elevator shown in fig. 3 will be described with reference to fig. 5. Fig. 5 is a block diagram showing an example of a hardware configuration of each device provided in the entrance/exit linkage system of the elevator.

Here, an example of the hardware configuration of the computer 60 provided in the gateway device 20, the communication switching device 30, the group management devices 40A to 40C, and the user information registration device 50 will be described. Here, each part of the computer 60 may be selected or rejected according to the function and the purpose of use of each device.

The computer 60 includes a CPU (Central Processing Unit) 61, a ROM (Read Only Memory) 62, and a RAM (Random Access Memory) 63, which are connected to a bus 64. And the computer 60 includes a display section 65, an operation section 66, a nonvolatile memory 67, a first communication interface 68, and a second communication interface 69.

The CPU61 is an example of a control unit, and reads program codes of software for realizing the functions of the present embodiment from the ROM62 and executes the program codes. The computer 60 may include a Processing device such as an MPU (Micro-Processing Unit) instead of the CPU 61. The RAM63 is used for temporarily writing variables, parameters, and the like generated in the middle of arithmetic processing by the CPU61 and the like.

The display unit 65 is, for example, a liquid crystal display, and displays the result of processing performed by the computer 60. The operation unit 66 is, for example, a keyboard, a mouse, a touch panel, or the like, and allows a user to perform predetermined operation input and instruction.

For example, the operation unit 66 may be deleted in the gateway device 20. The display unit 65 and the operation unit 66 can be deleted in the communication conversion apparatus 30 and the group management apparatus 40. When the user information registration device 50 and the information medium 10 are in a communicable state, the operation unit 66 can be operated to input a destination layer of the user to the information medium 10.

As the nonvolatile memory 67, for example, an HDD (Hard Disk Drive), an SSD (Solid State Drive), a flexible Disk, an optical Disk, a magneto-optical Disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, or the like can be used. The nonvolatile memory 67 may store a program for causing the computer 60 to function, in addition to an OS (Operating System) and various parameters. For example, the nonvolatile memory 67 of the communication converting apparatus 30 may store information on the stop level assigned to each bank (see fig. 2), a table T1 (see fig. 4), and the like.

The first communication interface 68 and the second communication interface 69 can transmit and receive various data between the respective devices via a network such as a wired or wireless LAN using, for example, a NIC (network interface Card) or the like. The first communication interface 68 may be an interface for performing communication using a near field communication technology such as NFC.

For example, the first communication control section 21 and the second communication control section 24 of the inlet and outlet device 20 (refer to fig. 3) correspond to the first communication interface 68 and the second communication interface 69. The first communication control section 31 and the second communication control section 34 of the communication conversion apparatus 30 correspond to the first communication interface 68 and the second communication interface 69. The communication control units 41A to 41C of the group management devices 40A to 40C correspond to the first communication interface 68.

The communication control unit 51 of the user information registration device 50 corresponds to the first communication interface 68. The first communication control unit 21 of the entrance device 20 and the communication control unit 51 of the user information registration device 50 communicate by short-range wireless communication. The communication control unit 51 constitutes a card reader/writer that reads information stored in an IC card or the like or writes information to the IC card.

[ display processing of gateway device ]

Next, the steps of the display processing method in the gateway device 20 will be described with reference to fig. 6. Fig. 6 is a flowchart showing an example of the steps of the display processing method in the gateway device 20. The CPU61 realizes the processing shown in fig. 6 by reading and executing programs stored in the ROM62 or the nonvolatile memory 67.

Since the door of the gateway device 20 is normally closed, the user brings the information medium 10 held by the user close to the reading surface of the gateway device 20 in order to pass through the gateway device 20 (the first communication control unit 21 in fig. 3). In this way, the security processing unit 22 of the gateway device 20 reads the user information stored in the memory of the information medium 10, and transmits the read user information to the communication conversion device 30 via the second communication control unit 24. Then, the communication switching device 30 performs a communication switching process for performing individual assignment based on the user information (S1). The details of this communication conversion processing will be described with reference to fig. 7 described later.

After that, the security processing unit 22 waits for the distribution unit data to be transmitted from the communication switching device 30, and periodically determines whether or not the distribution unit data is received (S2). When the distributed single-device data is not received (no in S2), the security processing unit 22 returns to the process of step S2 in which the communication conversion process is performed.

If the distributed stand-alone data is received in step S2 (yes in S2), the security processing unit 22 displays the distributed stand-alone on the display unit 23 (S3). The user confirms the assigned individual machine displayed on the display section 23 of the doorway device 20 and moves to a landing with the corresponding individual machine to wait for the arrival of the car.

As described above, when the destination floor of the user is not the bank common floor, the user information is transmitted to the group management device corresponding to the bank based on the destination floor information. However, when the destination floor of the user is a common floor for banks, if the individual assignment processing is performed based on only the destination floor information, the user may be guided to a different bank each time. As described above, for example, if the user is a user of a common floor (refer to fig. 2) of a bank of 10 floors, the user is assigned to a single elevator belonging to the bank B or the bank C. Then, the communication conversion apparatus 30 according to the present embodiment performs the following processing shown in fig. 7.

[ communication conversion processing of communication conversion device ]

Fig. 7 is a flowchart showing an example of the procedure of the communication conversion processing method in the communication conversion apparatus 30.

In fig. 7, when the bank determination unit 32 of the communication switching device 30 receives the user information of the information medium 10 from the gateway device 20, it determines whether or not the bank identification ID is included in the user information (S11). When the user information includes the bank identification ID, the bank determination unit 32 determines whether the bank identification ID is normal (S12), and then determines whether the group management device of the bank corresponding to the bank identification ID is normal (S13). Since it is normally normal (yes at S12, yes at S13), the bank decision section 32 transmits the user information including at least the bank ID and the destination layer information to the group management device corresponding to the bank, for example, the group management device 40B (S14).

On the other hand, when the group ID is abnormal in step S12 (no in S12) or when the group management apparatus of the target bank is abnormal in step S13 (no in S13), the bank determination unit 32 transmits data indicating that an abnormality, which is an exception, has occurred (an abnormality indication) for each case to the entrance apparatus 20, and causes the display unit 23 of the entrance apparatus 20 to display the abnormality indication (S17). After the bank determination unit 32 executes the process of step S17, it ends the process of the present flowchart.

For example, if 3 banks a to C exist in the elevator, but the user information includes a bank ID "DDD" indicating the bank D, it is determined that the bank ID is abnormal. The abnormality of the group management device means a case where a response signal from the group management device out of a normal range indicates an abnormal value or a case where the response signal is not returned.

After the process of step S14, the bank decision unit 32 decides whether or not reception of the distributed list data from the distributed group management device (for example, the group management device 40B) is being awaited (S15), and if reception of the distributed list data is being awaited (yes at S15), the decision process of step S15 is continued.

Next, if the reception of the distribution list data is not waited for in step S14, that is, if the distribution list data is received (no in S15), the bank determination unit 32 transmits the distribution list data to the entrance device 20 and causes the display unit 23 of the entrance device 20 to display the distributed list (S16). After the process of step S16 is completed, the bank determination unit 32 ends the process of this flowchart.

In addition, in step S11, if the bank identification ID is not included in the user information (no in S11), the bank determination unit 32 acquires the bank identification ID (decided bank identification ID) predetermined for the destination floor information, which is stored in advance in the nonvolatile memory 67 (S18). Then, the bank determination unit 32 proceeds to the process of step S13 after the process of step S18. In this case, in order that the user information of the information medium 10 does not include the bank identification ID, the bank identification ID is determined in advance for the destination layer information, and the information is registered as a table (not shown), and the table is generated in addition to the table T1 of fig. 2 and stored in the nonvolatile memory 67.

Then, in the group management device to which the assignment is made, for example, in the group management device 40B, the appropriate individual is assigned by the individual assigning section 42B based on the destination layer information included in the received user information as in the normal case, and the assigned individual data is notified to the display section 23 of the destination device 20 through the communication switching device 30.

Accordingly, the user of the bank common layer uses the same individual bank every time with exception (at the time of detecting abnormality at S12, S13) based on the bank ID stored in the information medium 10 owned by the user. This allows the user to assign the single machine only by using a specific hall (landing), thereby improving the convenience of the user. That is, it is possible to prevent the user of the common floor of the banks from being able to assign the individual machines of different banks at a time as in the prior art.

On the other hand, when the user information does not include the bank identification ID, the user information is transmitted to the group management device of the bank predetermined in association with the destination layer information, for example, the group management device 40B. Then, the same processing is performed in the group management device 40B. Therefore, even when the user information does not include the bank identification ID, the same bank and hall (hall) are used each time. In this way, the user can use the conventional bank and hall regardless of whether the bank shares the user of the floor or the user of another floor, or in the case where the user information does not include the bank identification ID.

[ ladder group assignment processing in user information registration apparatus ]

Next, an example of the procedure of the bank assignment processing method in the user information registration device 50 will be described with reference to fig. 8. Fig. 8 is a flowchart showing an example of the procedure of the bank assignment processing method in the user information registration device 50. By implementing this flowchart, the bank identification ID determined in accordance with the destination floor is registered in the information medium 10 regardless of whether the destination floor of the user is the bank common floor. While fig. 1 to 3 show a 3-bank structure such as banks a to C as an example, the example adopted in fig. 8 is an example assumed to be a 4-bank structure such as banks a to D.

In fig. 8, first, the information medium 10 is brought close to the reading surface of the user information registration device 50 (corresponding to the communication control unit 51 in fig. 3), the communication control unit 51 reads the user information from the memory of the information medium 10, and the data of the read user information is sent to the bank identification ID assignment processing unit 52. When the group ID assignment processing unit 52 detects that the information medium 10 approaches the reading surface, it determines whether or not the elevator has a plurality of groups (S21), and if not (no in S21), it ends the processing in the present flowchart. When the elevator does not have a plurality of banks, it is not necessary to assign the banks, and an appropriate single machine can be assigned only based on the destination floor information.

Next, when the elevator has a plurality of banks (yes in S21), the bank ID assignment processing unit 52 determines whether or not to use the bank common floor based on the read user information (S22). When the bank common layer is to be used (yes at S22), the bank ID assignment processing unit 52 calculates the number of users corresponding to the bank (S23). The number of users is an example of an index indicating the use requirement of each bank. For example, in the case where the destination floor is 10 floors, the number of users is counted for the bank B and the bank C. The user information registration device 50 accumulates information on the number of users (the number of the elevator groups and the number of the users) assigned to each elevator group, and can calculate the users of each elevator group based on the information on the number of the elevator groups and the number of the users.

Next, the bank ID assignment processing unit 52 calculates the bank with the least users among the plurality of banks for which the number of users has been calculated (S24). Then, the bank identification ID assignment processing unit 52 registers the bank identification ID indicating the bank with the smallest number of users as the user information in the information medium 10 through the communication control unit 51 (S25). The communication control unit 51 can not only read information from the information medium 10 but also write information in the memory of the information medium 10. After the process of step S25 ends, the process of the present flowchart ends.

On the other hand, if the bank common floor is not to be used in step S22 (no in S22), the bank ID assignment processing unit 52 determines whether or not the destination floor of the user information is the stop floor of the bank a (S26). Then, when the destination floor is the stop floor of the bank a (yes at S26), the bank ID assignment processing unit 52 registers the bank ID indicating the bank a as the user information in the information medium 10 via the communication control unit 51 (S27).

Next, when the destination floor is not the stop floor of the bank a (no in S26), the bank ID assignment processing unit 52 determines whether or not the destination floor is the stop floor of the bank B (S28), and when the destination floor is the stop floor of the bank B (yes in S28), registers the bank ID indicating the bank B as the user information in the information medium 10 (S29).

Next, when the destination floor is not the stop floor of the bank B (no in S28), the bank ID assignment processing unit 52 determines whether or not the destination floor is the stop floor of the bank C (S30), and when the destination floor is the stop floor of the bank C (yes in S30), registers the bank ID indicating the bank C as the user information in the information medium 10 (S31).

Next, when the destination floor is not the stop floor of the bank C (no in S30), the bank ID assignment processing unit 52 determines whether or not the destination floor is the stop floor of the bank D (S32), and when the destination floor is the stop floor of the bank D (yes in S32), registers the bank ID indicating the bank D as the user information in the information medium 10 (S33).

Next, when the destination floor is not the stop floor of the bank D (no in S32), the bank ID assignment processing unit 52 displays a screen indicating that the use floor included in the user information is abnormal on the display unit 53 of the user information registration device 50 (S34). After the end of any of the processing in steps S27, S29, S31, S33, and S34, the processing in this flow is ended.

By performing the above-described bank identification ID registration processing in the user information registration device 50, the bank identification ID corresponding to the destination floor is registered in the information medium 10 regardless of whether the destination floor of the user is the bank common floor.

The elevator to be controlled according to the above-described embodiment includes a plurality of banks a to C and group management devices 40A to 40C for group management of a plurality of individual machines in association with each other, and each of the banks a to C serves to have a bank-shared floor between them. In the present embodiment, the user information is read from the information medium 10 held by the user by the gateway device 20 (security processing unit 22), and the communication conversion process 30 performs control so that the group management devices 40A to 40C of the corresponding groups a to C perform assignment of individual machines based on the group identification ID of the user information. That is, the bank identification ID is registered in advance as user information in the user information medium 10, and the bank determining unit 32 of the communication switching device 30 transmits the user information for assigning a single machine to any one of the group management devices of the banks a to C corresponding to the bank identification ID.

Accordingly, the present embodiment guides the user to a landing of any one of the banks a to C indicated by the bank identification ID registered in the information medium 10. With this configuration, the user of the bank common layer can avoid assigning the individual to a different bank every time, and can assign the individual to the same bank almost except for an exception (when an abnormality occurs) based on the bank identification ID of the information medium 10 owned by the user. Therefore, the user can always use the single machine of the same ladder group and only use a specific ladder hall, thereby improving the convenience of the user.

The present invention is not limited to the above embodiments, and various other application examples and modifications can be made without departing from the scope of the present invention described in the summary of the invention.

For example, the above-described embodiments have been described in detail and specifically with respect to the configurations of the apparatus and the system for easy understanding of the present invention, but the present invention is not limited to the embodiments having all the configurations described. Moreover, a part of the structure of one embodiment may be replaced with the structure of another embodiment, and the structure of another embodiment may be added to the structure of one embodiment. Further, some of the configurations of the embodiments may be added, deleted, or replaced with other configurations.
