Description

  The present invention relates to a technology for an entrance / exit management system, and more particularly to a technology for grasping movement using an elevator.

  In an entrance / exit management system using a card (non-contact IC card), a card reader (non-contact IC card reader) and an electric lock are attached to the door of a living room (compartment) such as an office, and each individual (user) enters. If the authority to leave the room (permission / non-permission, etc.) is given, it is possible to grasp the exact location (position, location, etc.) of the individual.

  On the other hand, in a building such as a managed building, if you want to limit the moving floor of people who move using an elevator, control to automatically limit the moving floor (elevator stop floor) according to the authority setting for each individual The technology to perform is mentioned.

  For example, as shown in FIG. 10, the user can hold the card (74) over the card reader (72) installed in the elevator car (70) and press the moving floor button according to the authority set for each individual. Need to control. This prevents the elevators from stopping on floors that are not authorized for each user.

  In relation to the above, Japanese Patent Application Laid-Open No. 2003-276957 (Patent Document 1) discloses a technique for controlling the stop floor of an elevator with the authority given to each individual. For example, in FIG. 10, in the second to fourth floors of the building where the elevator is located, the room where the user A is permitted is only in the room A30 on the third floor. Therefore, in this case, control is performed so that the elevator cannot be stopped on the second floor and the fourth floor (for example, when the user's card is read by a card reader in the elevator, only the third floor button can be pressed). Thereby, security can be further strengthened in the system including the elevator.

  Japanese Patent Laid-Open No. 11-303478 (Patent Document 2) discloses that an electric lock is attached to an outer door of an elevator, and if the correct operation (password) is not performed, the elevator call button is operated to move by the elevator. Techniques have been disclosed that make it impossible to do so.

  Japanese Patent Laid-Open No. 5-250375 (Patent Document 3) notifies the floor number, zone number, and elevator stop impossibility information, and makes it impossible to stop the elevator to the floor to which each individual belongs based on the notification information. Although described, a specific control method is not described.

JP 2003-276957 A Japanese Patent Laid-Open No. 11-303478 JP-A-5-250375

  With the above entrance / exit management system, it is possible to roughly grasp and limit the location of the user. However, for example, as shown in FIG. 10, when a plurality of users (example: A, B) use the elevator (70) at the same time, a problem arises. For example, when the authority of user A and user B (rooms allowed, etc.) are different, the floor on which the elevator can be stopped is also different. For example, user A is permitted only on the third floor (rooms A30 and A32), and user B is permitted on the third floor (room A31) and the fourth floor (room A41).

  In this case, according to the prior art such as Patent Document 1, there is a problem that the user can get off to a floor that is not originally authorized. In the example of FIG. 10, the user A does not have the authority to get off the elevator to the fourth floor (Hall H4), but when the user B who has the authority gets down to the fourth floor (H4), the user A may get off at the same time. I can do it.

  Moreover, in the prior art, since there is the possibility as described above, it is impossible to accurately grasp on which floor the user who moved using the elevator got off (which position). For this reason, it is difficult to grasp the exact location of an individual such as the entrance / exit management system using a card for entering / exiting the room described above in the case of a system including the above elevator. was there.

  In view of the above problems, the main object of the present invention relates to an entrance / exit management system including an elevator, and even when a plurality of people (users) use an elevator, the authority granted to each individual Based on the above, it is to provide a technology that can realize accurate grasp of each person's location, restriction of movement, etc. including getting off the elevator on an unauthorized floor (section).

  In order to achieve the above object, a typical embodiment of the present invention is an entrance / exit management system including an elevator, and has the following configuration.

  In this entrance / exit management system, with regard to the movement (management, etc.) of a person (user) etc. who uses an elevator, a tag (semi-passive tag, etc.) that is attached to the object (person / thing) and moves A tag for transmitting the tag information (ID, etc.) from the tag, a plurality of trigger coils installed in an elevator, a hall (entrance / exit), and the like, a receiver for receiving the tag information etc. via the trigger coil, A controller that determines a target location (movement between sections, etc.) and authority (permission / non-permission of movement to sections, etc.) from tag information and outputs the result.

  Sections are configured according to the arrangement of walls and trigger coils. The hall in the elevator car and the hall in front of the elevator (entrance / exit) are managed as compartments. For example, the trigger coils are arranged in pairs. Movement between the sections is detected by a trigger coil disposed between the sections.

  In the control function of the present system (controller), for example, when the user (target) possessing the tag gets down (enters) into a hall section on a predetermined floor from a section in an elevator car, for example, the trigger coil, And based on the acquisition of tag information etc. through the receiver, etc., the location of the target (in which section, etc.) is detected and grasped. Then, based on the management information of the target authority, it is determined whether or not the authority related to the movement of the target, that is, whether or not getting down (entering) the relevant section is permitted. Then, when it is detected that the user has no authority to get down to the area, for example, an alarm signal (notification information) is generated to the alarm device or the system management server, and the location of the target is notified. To do.

  This system form is, for example, an entrance / exit management system that manages a building including an elevator, an RFID tag attached to an object that is a person or an object, at least the elevator in the building, and its getting on and off A plurality of trigger coils installed in the vicinity of the field corresponding to the configuration of the sections for transmitting tag information from the tags, a receiver for receiving information including the tag information via the trigger coils, and the reception A controller for acquiring information including the tag information through a machine, detecting movement between sections related to the tag target, determining authority for the movement, and controlling the movement. By arranging the trigger coil between the elevator and the landing area, it has at least a section in the elevator and a section of the landing area. And when the object of the tag gets off from the section in the elevator to the boarding area, the controller detects the movement and determines the authority of the movement.

  According to a typical embodiment of the present invention, even when a plurality of people (users) use an elevator, etc., based on the authority given to each individual, It is possible to achieve accurate grasp of each person's location and restriction of movement, including getting off the elevator on an unauthorized floor.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

[system]
FIG. 1 shows a hardware and software block configuration of the entrance / exit management system of the present embodiment. This system includes an elevator 70 (one or more), an operation panel 71 (inside and outside the elevator 70), an elevator instruction device (relay device) 72, a controller 30, a server 10, a display device (terminal) 20, an alarm device 60, and a receiver 40. , A trigger controller 50 (plural), a trigger coil 51 (plural), a tag 52 possessed by an object (person / thing), a network 90, and the like.

  For example, a user (person) possesses a tag 52 as an object. As the person moves, the tag 52 moves. When the object is an object, a tag 52 is attached to an article such as a notebook PC. The tag 52 moves when a person with the tag 52 carries it.

  The trigger coil 51 is an element that is installed in a passage in the building or in the elevator 70 and constitutes a section. The trigger coil 51 serves as a medium for generating a magnetic field and transmitting tag information from the tag 52 when the tag 52 passes. The tag 52 is an RFID tag such as a semi-passive tag and receives tag information (including ID and the like) upon receiving a magnetic field from the trigger coil 51. The receiver 40 receives and reads information from the tag 52 through the trigger coil 51 and transmits the read information to the controller 30. Information such as a trigger coil ID for identifying the trigger coil 51 is encoded in the reception information from the trigger coil 51 to the receiver 40 in addition to tag information (tag ID or the like). Therefore, the trigger coil 51 through which the tag 52 has passed can be identified and determined.

  The controller 30 is a characteristic processing unit, and based on information transmitted from the receiver 40, a target (user ID, etc.) corresponding to the tag 52 and a trigger coil 51 (trigger coil ID, etc.) through which the target has passed. ) And the like, and thereby processing such as detection, determination, and control of movement between target sections is performed. The controller 30 (or the server 10) manages information necessary for control such as target (person / thing) information, target tag 52 ID, section ID, trigger coil 51 ID, and the like (described later). 8 and 9).

  Information on the controller 30 can be collected and stored in the server 30 via the network 90. For example, information indicating which section the target is currently in is output from the controller 30 to the server 10 and recorded. The server 10 manages various types of information related to the entry / exit management. The administrator or the like can check the various types of information on the display device (terminal) 20 or can manage the management information (configuration information (ID, etc.) of each device. Etc.) can be set. Further, the management information can be reflected and set from the server 10 to each device such as the controller 30 via the network 90.

  The elevator instruction device (relay device) 70 is a device according to a known technique that instructs and controls the operation of the elevator 70. The elevator instruction device (relay device) 70 operates the elevator 70 in accordance with a user's operation on the operation panel 71 (such as pressing a destination floor button or a door opening / closing button).

  The trigger controller 50 controls the trigger coil 51 connected correspondingly. Each trigger controller 50 is connected to the controller 30 and the server 10. The trigger controller 50 also manages information such as the ID (trigger coil ID) of each corresponding trigger coil 51. Information such as the trigger coil ID can be set from the server 10 to each trigger controller 50.

  The alarm device 60 issues an alarm to an administrator or a target in accordance with control (such as an abnormal signal) from the controller 30.

  In addition, a system form using a non-contact IC card 74 (which the user has) and a non-contact IC card reader 72 (for example, a system form combined with an existing card entry / exit management system) can be used. Preparation is not essential. When the card reader 72 is used, for example, the card reader 72 is provided in the elevator 70 so as to be interlocked with the operation panel 71. For example, it has a function of restricting the elevator stop floor of the user according to the presence or absence of the user's authority by the authentication of the user's card 74. Also, by providing a card reader 72 at the door of each room, entry / exit management for the room is performed.

[Basic configuration example]
FIG. 2 shows an example of the basic configuration of an entrance / exit management system according to an embodiment of the present invention. The elevator (elevator car) 70 is connected to the controller 30 through the operation panel 71 (71A, 71B), the relay device 73, and the like. An object such as a user carrying the tag 52 gets in the elevator 70. A trigger controller (TC) 50 is connected to each trigger coil 51 (51A to 51D). Each TC 50 is connected to the controller 30 via a network 90, for example. In addition, the receiver 40 is provided within a range where transmission (wireless) from each trigger coil 51 can reach.

  The elevator 70 side has a door 81A, an operation panel 71A, and the like. Correspondingly, the elevator hall (H) has a door 81B, an operation panel 71B, and the like.

  Further, the above-described card reader 72 may be provided in the elevator 70 at a position such as the operation panel 71A. Thereby, for example, a control function of a moving floor (stop floor) for each user is provided. In this case, the system configuration uses both the tag 52 and the card 74.

  This system has “partitions” that are virtual units (areas) for managing the location of the target. This section is not limited to a space such as a physically closed room. In this system, an elevator (elevator car) 70 is defined as a section, for example, section E, and a section (unit divided by a wall, a trigger coil 51, or the like) in front of the elevator 70 in the hall (H) is divided into, for example, sections. Manage as A. An example of another section continuously connected to the section A via the trigger coil 51 is referred to as a section B. The direction A is a movement (when getting off from the elevator 70) from the section E in the elevator 70 to the section A of the hall (entrance / exit). A direction B is a movement (in the case of getting on the elevator 70) from the section A of the hall (the landing) to the section E in the elevator 70.

  A trigger coil 51 is disposed (laid) between the sections. Between the section E and the section A, a pair of trigger coils 51A and 51B is disposed. Between the section A and the section B, a pair of trigger coils 51C and 51D is disposed. In particular, the present embodiment is an example in which one trigger coil 51A of the pair is provided in the elevator 70, and the other trigger coil 51B is provided in the vicinity of the door 81B on the hall side. When the trigger coil 51 is provided in the elevator car 70, there are various ways of laying, for example, by arranging a loop of the trigger coil 51 on the ceiling surface.

  As another embodiment, the trigger coil 51 (51A) may not be provided in the elevator car 70, but the trigger coil 51 may be provided in pairs near the hall-side door 81B.

  In the above configuration, when a target (for example, a person) having the tag 52 descends from the section E in the elevator 70 to the section A of the hall as in the direction A, the pair of trigger coils 51A and 51B The tag information (and the trigger coil ID of the corresponding trigger coil 51, etc.) is acquired to the controller 30 via the receiver 40. The same applies to the direction B. Thereby, the movement between division | segmentation EA of object can be detected. The controller 30 determines the authority of the target along with the detection of the movement between the target sections. For example, when the object is not authorized to enter the section A from the section E (when the section A is not permitted), for example, the controller 30 notifies the server 10 of an abnormality and the alarm device 60 is sounded. Similarly, when the object moves from the section A to the section B, it is detected through a pair of trigger coils 51C and 51D. For example, when the object is not authorized to enter the section B from the section A, an abnormality is notified.

  The controller 30 determines the direction and location of movement of the target between sections based on the detection / reading order of each tag 52 (tag information) on the time axis (for example, the passing order of the tag 52 of the pair of trigger coils 51). Can be determined. For example, if the detection is performed in the order of the first trigger coil 51A and the second trigger coil 51B, it can be determined that the movement is from the section E to the section A as in the direction A, and the detection can be performed in the reverse order. For example, it can be determined that the movement is from the section A to the section B as in the direction B. If the trigger coil 51D is detected next to the trigger coil 51A, it can be determined that the user is in the section A.

[Application configuration example]
In FIG. 3, based on FIG. 1, FIG. 2, the example of a concrete application structure according to the building of management object is shown. This is a case where there are two elevators 70. This entrance / exit management system includes a controller 30 (30a, 30b), a trigger controller 50 {50x, 50y, 50ab, 50cd, etc.}, a trigger coil 51 {51x, 51y, 51a, 51b, 51c, 51d, etc.}, an elevator 70 ( 70x, 70y) and other components similar to those described above (the operation panel 71 on the hall side is omitted).

  Examples of the sections include a section X in the first elevator 70x, a section Y in the second elevator 70y, one section FA in front of the elevators 70x and 70y, a section FB connected from the section FA to the back, and the like.

  Also, for example, one of the two controllers 30 (30a) is used for elevator movement floor control in the case of the system using the card reader 72 described above (the card reader 72 is not shown), and the other (30b) is used as shown in FIG. This is a configuration example for the same main control (for trigger coil 51 control).

[Building example]
FIG. 4 shows a layout configuration example in a building to be managed in this system. There is an elevator 70 that leads from the first floor (1F) to the fourth floor (4F). There is an elevator hall H (H1 to H4) for getting on and off the elevator 70 on each floor. It is connected to each room (A20 etc.) from the hall or passage. Target users, for example, A and B, each have a tag 52. In addition, although it is a case of the system form which does not use the card reader 72, when using, it is provided in the elevator 70, the door of a room, etc. Users A and B are each given authority. For example, both the users A and B are permitted (OK) to get on the elevator 70 from the hall H1 on the first floor. Further, the user A is permitted to enter the rooms A30 and A32 on the 3rd floor, and the other rooms are not permitted (NG). User B is allowed to enter room A31 on 3F and room A41 on 4F, and the other rooms are not allowed (NG). User A is allowed to get off the elevator 70 to 3F hall H3 (to go to room A30). User B is allowed to get off from elevator 70 to halls H3 and H4 in 3F and 4F (to go to rooms A31 and A41). The same applies to the reverse direction (the direction from the room to the elevator 70 and returning to 1F).

  FIG. 5 shows a configuration example such as a section in the vicinity of the hall in the building of FIG. 4 and the arrangement of the trigger coil 51. (A) is for the first floor and (b) is for the fourth floor. T represents the trigger coil 51 and its ID. For example, T4a corresponds to 51a in FIG. 3, and Tx corresponds to 51x. Of the space such as the hall H, the area immediately before the elevator 70 is referred to as a boarding / alighting hall.

  In FIG. 5 (a), there is a section 1F1 of a hall H1 of 1F, and it is possible to get on and off two elevators 70x and 70y. The sections in the elevators 70x and 70y are sections X and Y. On the left hand side of the hall H1, there is a section 1F2 leading to, for example, a staircase or the like (partitioned by trigger coils T1c and T1d).

  In FIG. 5B, in the hall H4 on 4F, there is a boarding area 4F1 in front of the elevators 70x and 70y. On the right hand side from the elevator 70, there is a section 4F2 connected to the section 4F1, and further to the back section 4F3. Examples of the trigger coil 51 include Tx and T4a between sections X-4F1, Ty and T4b between sections Y-4F1, T4c and T4d between sections 4F1 and 4F2, T4e and T4f between sections 4F2 and 4F3, and the like.

  Also, for example, an alarm device 60 is provided in each of the sections 4F1 and 4F2, and an alarm or warning is issued in the case of unauthorized intrusion (abnormality notification) or the like. The section 4F3 is a passage connected to each room, for example. A card reader 72 may be provided at the position of the door in each room to manage entry / exit of the compartments in units of rooms. Or it is good also as a structure which provides the pair of trigger coils 51 in the position of the door of each room, In that case, the detection of the movement between divisions, etc. are implement | achieved similarly to the divisions near an elevator hall.

  Also, the 2F hole H2 and the 3F hole H3 are the same as those shown in FIG. Hereinafter, as an example, a case will be described in which a target (user) moves between the hole H1 of 1F in FIG. 5A and the hole H4 of 4F in FIG. 5B.

[Table (1)]
The table (target authority management information) in FIG. 8 is a configuration example of authority management information related to a partition, which is assigned to each target (user). Sections include not only areas such as halls and passages, but also rooms and elevators. For each user, the permitted and unpermitted sections are managed. The non-permission is “0” and the permission is “1”. Each section is managed by an ID or number such as “1F1”. For example, the sections “A20” to “A42” indicate rooms (FIG. 4), and the sections “1F1” and the like, and the sections “X” and the like indicate the sections shown in FIG. For example, looking at the authority of users A and B, the sections X and Y in the elevators 70x and 70y and the section 4F1 in front of the elevators 70x and 70y of 4F are both permitted. In addition, regarding the section 4F2 and the like further from the section 4F1, the user A is not permitted and the user B is permitted.

  In this example, as shown in FIG. 4, the floor (4F) in which the user (for example, A) is basically not authorized is permitted to get on and off at the section 4F1 in front of the elevator 70, and the interior is deeper than that. This is a case where the advance to the section 4F2 or the like is prohibited. In the case where unauthorized control of getting off to the section 4F1 in front of the elevator 70 is not permitted, it can be realized by changing the setting of the table in FIG.

[Table (2)]
The table (detection pattern management information) in FIG. 9 is a configuration example of management information used for detecting movement between target sections. Defines the detection pattern of the movement source / destination section based on the relationship between the two trigger coils 51 (first (pre-detection) trigger coil, second (rear detection) trigger coil) when tag information is read. . “Pattern” indicates a number for identifying a detection pattern. The pattern here is different from the movement pattern in FIG. The “first (pre-detection) trigger coil” is the ID of the trigger coil 51 detected before in time among the two. The “second (post-detection) trigger coil” is the ID of the trigger coil 51 detected later in time among the two. “Move source partition” and “Move destination partition” indicate the ID of each partition. Although only some definitions for 1F and 4F are shown, information of all patterns is defined and held.

  Further, for example, when the first trigger coil and the second trigger coil are the same, it can be determined that the movement source section and the movement destination section are the same (no movement between sections). For example, when the first trigger coil and the second trigger coil are the same T1a, it can be determined that the movement source section and the movement destination section are the same section 1F1.

  Moreover, although the example mentioned above is a control example at the time of getting off from the elevator 70 to the section of the hall, it can be similarly realized when getting on the elevator 70 from the section of the hall.

[Example of movement pattern]
6 (a) to 7 (f) show the example (Pa ~ Pf) of a part of the movement pattern between the user compartments in the case of the hole H4 of 4F in FIG. 5 (b). Yes. There are patterns related to various subsequent movements in the case of getting off from the first elevator 70x (section X) to the section 4F1 of the landing hall of the hall H4 on 4F.

  In FIG. 6A (referred to as a movement pattern Pa), the user carrying the tag 52 moves down from the elevator 70x (section X) and enters the section 4F1 of the hall, and from there again, the same elevator 70x (section) X). That is, the order (location) of the user (tag 52) in Pa is (1) X → (2) 4F1 → (3) X. In the case of Pa, tag information transmitted from the tag 52 that has passed through the pair of the first trigger coil Tx and the second trigger coil T4a at the time of detection is transmitted to the controller 30 (30a, 30b) via the receiver 40. Sent to. Then, the controller 30 determines that the detection pattern corresponds to the patterns 15 and 16 in FIG. As a result, it is determined that the current final destination section is the section X (that is, in the elevator 70x). At this time, the controller 30 refers to the table of FIG. 8, and the authority regarding the section 4F1 is “permitted (1)” for both the users A and B. Therefore, in this case, no abnormality notification to the alarm device 60 or the server 10 occurs.

  In FIG. 6B (movement pattern Pb), the user (tag 52) gets out of the first elevator 70x (section X) and enters the hall section 4F1, and then the second elevator 70y (section Y). It is a case of getting on. That is, the order in Pb is (1) X → (2) 4F1 → (3) Y. In the case of Pb, the section X passes through Tx and T4a and enters the section 4F1, passes through T4b and Ty, and enters the section Y. In the case of Pb, it corresponds to the patterns 15, 20, and 18. Since the authority regarding the section 4F1 is permitted for both the users A and B, no abnormality notification is generated as in the case of Pa.

  FIG. 6C (movement pattern Pc) shows that the user (tag 52) gets off the elevator 70x (section X) and enters the hall section 4F1, enters the right section 4F2 and then enters the section 4F1. It is a case where it returns and it gets on the elevator 70x (compartment X). That is, the order in Pc is (1) X → (2) 4F1 → (3) 4F2 → (4) 4F1 → (5) X. In the case of Pc, the section X passes through Tx and T4a, passes through T4c and T4d, and reaches the section 4F2. In the case of Pc, it corresponds to the patterns 15, 24, 28, 29, 25, and 16. The authority regarding the section 4F2 is not permitted for the user A and permitted for the user B. Therefore, the controller 30 generates an abnormality notification for the user A when the user A passes T4d and enters the section 4F2 (at the time of pattern 28).

  FIG. 7 (d) (movement pattern Pd) shows that the user (tag 52) gets off the elevator 70x (section X) and enters the hall section 4F1, enters the right section 4F2 and then enters the section 4F1. It is a case where it goes back and gets on the 2nd elevator 70y (section Y). That is, the order of Pd is (1) X → (2) 4F1 → (3) 4F2 → (4) 4F1 → (5) Y. In the case of Pd, it corresponds to the patterns 15, 24, 28, 29, 27, and 18. Since the authority regarding the section 4F2 is not permitted for the user A and permitted for the user B, the controller 30 controls the user A when the user A enters the section 4F2. Anomaly notification is generated.

  FIG. 7 (e) (movement pattern Pe) shows that the user (tag 52) gets out of the elevator 70x (section X) and enters the hall section 4F1, then enters the right section 4F2, and further from there. This is a case where the vehicle enters the section 4F3 and returns to the section 4F2 and the section 4F1 and gets on the elevator 70x (section X). That is, the order at Pe is (1) X → (2) 4F1 → (3) 4F2 → (4) 4F3 → (5) 4F2 → (6) 4F1 → (7) X. In the case of Pe, similarly to the above, it reaches the section 4F2, and further passes from the section 4F2 through T4e and T4f to the section 4F3. In the case of Pe, it corresponds to the patterns 15, 24, 28, 32, 34, 35, 33, 29, 25, and 16. The authority regarding the sections 4F2 and 4F3 is not permitted for the user A and permitted for the user B. Therefore, the controller 30 detects the user at the time when the user A passes T4d and enters the section 4F2 (at the time of pattern 28) and at the time when the user A passes through T4f and enters the section 4F3 (at the time of pattern 32). An abnormality notification for A is generated.

  FIG. 7 (f) (movement pattern Pf) shows that the user (tag 52) gets out of the elevator 70x (section X) and enters the hall section 4F1, enters the right section 4F2, and further from there. This is a case where the vehicle enters the section 4F3 and then returns to the section 4F2 and the section 4F1 and gets on the second elevator 70y (section Y). That is, the order in Pf is (1) X → (2) 4F1 → (3) 4F2 → (4) 4F3 → (5) 4F2 → (6) 4F1 → (7) Y. In the case of Pf, it corresponds to the patterns 15, 24, 28, 32, 34, 35, 33, 29, 27, and 18. An abnormality detection for user A is generated in the same manner as Pe.

  As in the above example, the movement of the user (tag 52) to a section that does not have permission is detected and an abnormality notification is automatically generated. As a result, when the target of the tag 52 is a user, it is possible to detect and warn of unauthorized intrusion or the like into the unauthorized section.

[Effects]
As described above, according to the entrance / exit management system of the present embodiment, even if a plurality of objects (users, etc.) use the elevator 70 at the same time, the floor without authority is based on the authority for each object. It is possible to accurately grasp the location of each target, restrict movement (such as abnormality notification), and the like, including getting off the elevator 70 and getting on the elevator 70. That is, it is possible to improve the security of the entrance / exit management system including the elevator.

  In the example of FIG. 4, when the authorized user B gets off from the elevator 70 to the hall H4 on the 4th floor, the user A gets off at the same time, and the user A has the right to enter (be in) the section. If not, it can be detected and grasped.

  As an example of the operation of this system, when the target of the tag 52 is an object, it is possible to detect, warn, etc., illegal take-out of the object outside the permitted section. For example, a person is provided with the tag 52, and the tag 52 is attached to an article such as a notebook PC, for example, and authority management information is set for each. A combination of both will also work. In addition, for example, setting / control that prioritizes the authority of an object (for example, permission to move to a certain section) over the authority of a person (for example, permission to move to a certain section) is also possible.

  Further, as described above, a system configuration in combination with an entrance / exit management system using a known card reader 72 is also possible. If there is an entrance / exit management system using an existing card reader 72 in a building to be managed, elements such as the trigger coil 51 and the controller 30 unique to this system may be added as they are. When used in combination, the card 74 and the tag 52 may be integrated.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say.

  For example, in the present embodiment, a set of two trigger coils 51 is arranged between the sections, but the present invention is not limited to this, and one or three or more trigger coils 51 are possible. For example, if it is technically possible to detect with one trigger coil 51 including the direction of passage, one trigger coil 51 may be arranged between the sections.

  For example, in this embodiment, there are a plurality (two) of elevators 70 for the elevator hall, and the boarding area is managed as one section (for example, section 4F1). It may be divided and managed in a plurality of sections corresponding to the field (a pair of trigger coils 51 is arranged between each section).

  The present invention can be used for an entrance / exit management system and the like.
