Embodiment 1 FIG.
FIGS. 1 to 5 relate to Embodiment 1 of the present invention. FIG. 1 is a block diagram showing the configuration of an entrance / exit management device, and FIG. 2 shows information stored in a storage unit included in the entrance / exit management device. FIG. 3 is a flowchart showing the operation of the entrance / exit management device, FIG. 4 is a diagram explaining the operation of the entrance / exit management device for a normal user, and FIG. 5 is a case where the user is not a normal user of the entrance / exit management device. It is a figure explaining operation | movement of.

  The interior of a facility or building to which the entrance / exit management device of the present invention shown in FIG. 1 is applied is partitioned and provided with compartments. A door (not shown) is provided at the entrance / exit of each section so as to be freely opened and closed. Each user who enters and exits the compartment has an ID tag (not shown). In each ID tag, identification information capable of uniquely identifying each of a plurality of users is recorded in advance.

  The ID tag is a so-called active RFID (Radio Frequency IDentification) tag. That is, the ID tag can transmit the identification information stored therein as a radio signal. The ID tag incorporates a battery that supplies power for transmitting a radio signal.

  A reading unit 10 is installed in the vicinity of the compartment door. The reading unit 10 is for reading the identification information recorded on the ID tag by wireless communication. The reading unit 10 processes an antenna unit (not shown) for receiving a radio signal (electromagnetic wave) transmitted from the ID tag and processes the radio signal received by the antenna unit to acquire identification information and the like included in the radio signal. A signal processing unit (not shown) is provided.

  A predetermined constant whether or not there is an ID tag carried by the user within a range in which the reading unit 10 can receive a radio signal transmitted from the ID tag (hereinafter referred to as “reception range”). It is confirmed at the reading cycle. When an ID tag carried by the user enters the reception range, the ID tag transmits a radio signal including identification information recorded on the ID tag. The reading unit 10 receives a radio signal transmitted from the ID tag and acquires identification information included in the received radio signal.

  Therefore, the ID tag identification information is acquired by the reading unit 10 simply by entering the reception range while the user has the ID tag. As will be described later, the reception range of the reading unit 10 can be selectively changed between the first area and the second area. The initial state of the reception range of the reading unit 10 is the first area.

  An ID tag is an example of an information recording medium possessed by a user, in which identification information is recorded, and the identification information is read by wireless communication. As such an information recording medium, in addition to the active RFID tag described above, a so-called standby communication system (a system in which a radio signal is transmitted from the tag only when the tag is within the tag detection range) is so-called. A semi-active RFID tag can also be used. By using a semi-active RFID tag, the opportunity to transmit a radio signal from the ID tag is limited only when necessary, and unnecessary consumption of the battery built in the ID tag can be suppressed.

  The identification information of the ID tag read by the reading unit 10 is input to the authentication unit 20. The authentication unit 20 is for authenticating the user of the read identification information based on the identification information read by the reading unit 10. The authentication unit 20 includes a traffic authority authentication unit 21 and a normal use determination unit 22.

  In the storage unit 30, information on whether or not the user has the right to pass through the door of the identification information and whether or not the user is a normal user of the door is stored in advance in association with the identification information. Has been. An example of information stored in the storage unit 30 is shown in FIG.

  As described above, the information stored in the storage unit 30 includes, for each identification information of each user, whether or not the user has the right to pass the door for each door to be managed. The information includes information on whether or not the user is a normal user of the door when the user has the right to pass through the door.

  In the example of FIG. 2, when the number “1” or “2” is registered, it means that the user has the right to pass through the door. On the other hand, if nothing is registered, it means that the user does not have the authority to pass through the door.

  And regarding the door which has a passage authority, "1" means that the door is a door which a user does not normally use, ie, a user is not a normal user of the door. Further, “2” means that the door is a door that is normally used by the user, that is, the user is a normal user of the door.

  Therefore, specifically, in accordance with the example of FIG. 2, the user a does not have the authority to pass through the door A, but has the authority to pass through the door B and the door C. And about the door B and the door C which have a passage authority, the user a is not a normal user of the door B but a normal user of the door C.

  Further, the user b does not have the authority to pass through the door A, but has the authority to pass through the doors B and C. And about the door B and the door C which have passage authority, the user b is not a normal user about both the door B and the door C.

  Similarly, the user c has the authority to pass through the doors A and B and does not have the authority to pass through the door C. And about the door A and the door B which have a passage authority, the user c is not a normal user of the door A but a normal user of the door B.

  Here, the normal user of the door means a person who uses the door on a daily or frequent basis due to circumstances such as the presence of the door on a route on which the user passes on a daily basis. Therefore, when a normal user passes near the door, in most cases, the normal user has an intention to go through the door.

  The passage authority authentication unit 21 of the authentication unit 20 refers to the information stored in the storage unit 30 having the content described above, and the user of the identification information read by the reading unit 10 has the door passage authority. Authentication is performed.

  In the information stored in the storage unit 30, when the user of the identification information read by the reading unit 10 has the right to pass through the door (that is, when “1” or “2” is registered) In this case, the passage authority authenticating unit 21 authenticates the user as a person having the door passage authority (successful authentication).

  On the other hand, in the information stored in the storage unit 30, if the user of the identification information read by the reading unit 10 does not have the authority to pass through the door (that is, if nothing is registered), The authority authentication unit 21 does not authenticate the user as a person who has the authority to pass the door (authentication failure).

  The normal use determination unit 22 of the authentication unit 20 determines whether or not the user is a normal user of the door for the user who has been authenticated as the person having the door pass authority by the pass authority authentication unit 21. . This determination is made with reference to the information stored in the storage unit 30.

  When the user is authenticated as a user having the right to pass through the door by the right-of-passage authentication unit 21, either “1” or “2” is registered for the user in the information stored in the storage unit 30. Should have been.

  The normal use determination unit 22 determines that the user is not a normal user of the door when “1” is registered for the door. On the other hand, if “2” is registered for the door, the normal use determination unit 22 determines that the user is a normal user of the door.

  The reading unit 10 includes a reception range changing unit 11. The reception range changing unit 11 is for selectively changing the reception range of the reading unit 10 between the first area and the second area. The reception range changing unit 11 sets the size of the reception range to either the first area or the second area by changing the radio wave output from the antenna of the reading unit 10.

  The first area is an initial state of the reception range of the reading unit 10. The second area is set in a range closer to the door than the first area. Here, the first area is set as a substantially semicircular area in front of the door. The second area is narrower than the first area and is set as a substantially semicircular region included in the first area. Therefore, the second area is in front of the door and is closer to the door than the first area.

  An electric lock system 40 is provided at each door of the compartment. The electric lock system 40 includes a control unit 41, and the lock state of the electric lock of each door is controlled by the control unit 41. The electric lock of each door is locked in the initial state.

  When the normal use determining unit 22 determines that the user is a normal user of the door, the control unit 41 unlocks the electric lock of the door. Therefore, the user can pass through the door.

  On the other hand, when the normal use determining unit 22 determines that the user is not the normal user of the door, the control unit 41 maintains the locked state without unlocking the electric lock of the door at this time. In this case, the reception range changing unit 11 changes the reception range of the reading unit 10 from the first area to the second area.

  After the reception range of the reading unit 10 is changed to the second area, when the user further approaches the door, the user enters the reception range that has become the second area. Identification information of the possessed ID tag is read again by the reading unit 10. The control unit 41 unlocks the electric lock of the door when the identification information of the ID tag possessed by the user is read again by the reading unit 10. Thus, the user can pass through the door.

  The normal user determination by the normal use determination unit 22 is performed for a person who has been authenticated by the pass authority authentication unit 21 as a person having the pass authority of the door. Therefore, the user who is determined to be a normal user of the door by the normal use determination unit 22 naturally has the right to pass through the door. In addition, a user who is determined not to be a normal user of the door by the normal use determination unit 22 is also a person who has the authority to pass the door.

  On the other hand, as a result of the authentication by the passage authority authenticating unit 21, if the user is not authenticated as the user having the door passage authority, the normal user determining unit 22 does not determine the normal user, and the control unit 41 The doors are not unlocked. Therefore, the electric lock of the door remains locked, and the user who has not been authenticated as the person having the authority to pass the door is prevented from passing the door. In this case, the reception range of the reading unit 10 remains the first area.

  Next, the operation flow of the entrance / exit management apparatus configured as described above will be described with reference to the flowchart of FIG. First, the reception range of the reading unit 10 is set to a wide first area. In this state, in step S1, when the reading unit 10 detects an ID tag possessed by the user within the reception range (first area), the reading unit 10 reads the identification information recorded on the ID tag. .

  And it progresses to step S2, and the passage authority authentication part 21 of the authentication part 20 confirms whether the user of the identification information read by the reading part 10 has the passage authority of a door. If the user does not have the authority to pass through the door, the process returns to step S1. If the user is authorized to pass through the door, the process proceeds to step S3.

  In step S3, the normal use determination unit 22 of the authentication unit 20 determines that the user possessing the ID tag of the identification information that has been authenticated as having the right to pass the door in step S2 is the normal user of the door. It is determined whether or not. If the user is a normal user of the door, the process proceeds to step S4.

  In step S4, the control unit 41 of the electric lock system 40 unlocks the electric lock of the door. And in the following step S5, the control part 41 locks the electric lock of the said door. The locking in step S5 is performed after a certain time has elapsed after the unlocking in step S4. Alternatively, a sensor for detecting the open / closed state of the door may be provided, and the door may be locked when the door is opened and closed once after unlocking in step S4. After step S5, the process returns to step S1.

  On the other hand, if the user is not a normal user of the door, the process proceeds to step S6. In step S6, the reception range changing unit 11 changes the reception range of the reading unit 10 from the first area to the narrow second area. In subsequent step S7, it is confirmed whether or not the ID tag of the identification information authenticated in step S2 is detected again within the reception range changed to the second area.

  If the authenticated identification information is read from the ID tag by the reading unit 10 and the ID tag is detected again in the second area, the process proceeds to step S8. In step S8, the reception range changing unit 11 returns the reception range of the reading unit 10 from the second area to the first area. And it progresses to step S4 and the control part 41 of the electric lock system 40 unlocks the electric lock of a door.

  On the other hand, if the ID tag of the identification information authenticated in step S2 is not detected in the second area in step S7, the process proceeds to step S9. In step S9, the reading unit 10 checks whether or not a predetermined time has elapsed since the reception range was changed to the second area in step S6. If a certain time has not elapsed since the reception range was changed to the second area, the process returns to step S7.

  On the other hand, if a certain time has elapsed since the reception range was changed to the second area, the process proceeds to step S10. In step S10, the reception range changing unit 11 returns the reception range of the reading unit 10 from the second area to the first area. Then, the process returns to step S1.

  Through the processes in steps S7, S9, and S10, the reception range changing unit 11 is authenticated by the reading unit 10 within a predetermined time after changing the reception range of the reading unit 10 from the first area to the second area. If the user identification information is not read, the reception range of the reading unit 10 is returned from the second area to the first area.

  The entrance / exit management device configured as described above is associated with each of the reading unit 10 that reads the identification information recorded on the information recording medium possessed by the user and exists within the reception range, and the identification information. A storage unit 30 for storing in advance information on whether the user has the right to pass through the door of the identification information and whether the user is a normal user of the door; and information stored in the storage unit 30 Referring to FIG. 5, the passage authority authentication unit 21, which is an authentication unit for authenticating whether the user of the identification information read by the reading unit 10 has the door passage authority, and stored in the storage unit 30. A normal use determination unit 22 that is a determination unit that refers to the information and determines whether the user authenticated by the authentication unit as a person having authority to pass through the door is a normal user of the door; The authenticated user is When the determination unit determines that the user is not a regular user, the changing unit changes the reception range of the reading unit from the first area to the second area set closer to the door than the first area. A receiving range changing unit 11 and a control unit 41 that unlocks the door when the reading unit 10 reads the authenticated user identification information in the second area are provided.

  And the control part 41 unlocks | releases the said door, when a judgment means (normal use judgment part 22) judges that the said authenticated user is a normal user of the said door.

  For this reason, as shown in FIG. 4, when the user D who is a normal user of the door approaches the door, if the ID tag d possessed by the user D enters the first area, the reading unit 10, the identification information is read. As a result of the authentication of the traffic authority by the traffic authority authenticating unit 21 and the determination of the normal user by the normal usage determining unit 22, the door is immediately unlocked.

  Also, as shown in FIG. 5, when a user E who is not a normal user of the door approaches the door, if the ID tag e possessed by the user E enters the first area, the user D's The identification information is read by the reading unit 10 as in the case.

  As a result of authentication by the passage authority authenticating unit 21, it is confirmed that the user E has the authority to pass. As a result of subsequent determination by the normal use determining unit 22, it is confirmed that the user E is not a normal user. Even though the user E is a person who has the authority to pass, the door is not unlocked at this time ((1) in FIG. 5).

  In this case, the reception range changing unit 11 narrows the reception range of the reading unit 10 from the first area to the second area ((2) in FIG. 5). Then, when the user E further enters the second area after tangent to the door, the door is unlocked for the first time and can pass ((3) in FIG. 5).

  At this time, even if the passage authority authenticating unit 21 is authenticated to have the passage authority, if the user E does not enter the second area within a certain period of time, the user E is notified. It can be determined that there is no intention to pass through the door. Therefore, the door is not unlocked, and the reception range changing unit 11 returns the reception range from the second area to the first area.

  Thus, the entrance / exit management device of the present invention changes the size of the reception range of the reading unit 10 depending on whether or not the user who has the authenticated ID tag is a normal user of the door. For this reason, if it is a normal user of a door, it will be unlocked and will be able to pass through the door when it enters in the 1st wide area.

  On the other hand, if the user is not a normal user of the door, the door is not unlocked when entering the first area, and the door is unlocked when entering the narrower second area. In addition, if the user does not enter the second area within a certain time after entering the first area if the user is not a normal user of the door, the door is locked without being unlocked. Is maintained.

  Therefore, the door is inadvertently unlocked when a user who does not normally use the door and does not intend to pass through simply passes near the door without impairing convenience for a normal user who normally passes the door. Can be suppressed.
