In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted. In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted. Each management area including the passage is basically a space that does not have any means other than the area partitioning means 3. Of course, this does not exclude even normal entry / exit such as entering / exiting through a window.

  1 to 6, 4 is an RFID tag reading area around the area partition means 3, and 5 is an antenna unit connected to the communication control unit 2 that emits a beam to the RFID tag reading area 4. ˜5i are antenna units installed on the security doors 3a to 3i, respectively, and 5j is an antenna unit installed on the door 3j. 6 is a server (control unit) constituting the communication control unit 2, 7 is an RFID reader / writer constituting the communication control unit 2 to which the antenna unit 5 is connected, and a plurality of RFID reader / writers 7 are wired or wirelessly connected to the server 6 Are connected to each other. The antenna unit 5 (antenna units 5a to 5j) is a radio wave type antenna that uses a UHF band or a millimeter wave band, but the path-restricted RFID system according to the present invention uses an electromagnetic induction method that uses the HF band. The present invention can also be applied to an RFID system that uses another communication method such as. The security door 3 may be controlled on the server 6 side or on the RFID reader / writer 7 side. In the drawing, the connection relationship between the server 6 or the RFID reader / writer 7 and the area partitioning means 3 is omitted. In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted.

  1 to 6, 8 is a cable (LAN cable or coaxial cable) for connecting the communication control unit 2 or RFID reader / writer 7 and the antenna unit 5, and 9 is a connection between the communication control unit 2 and the RFID reader / writer 7. LAN cable. It is assumed that the LAN cable 9 includes not only a wired cable but also a wireless cable. That is, the network between the server 6 and the RFID reader / writer 7 may use a wired LAN and a wireless LAN independently, or may use both. 10 is a coaxial cable that connects the RFID reader / writer 7 and the antenna unit 5, 11 is a display unit that is a display unit (informing unit), 12 is a rotating lamp that is an informing unit, 13 is a display unit 11, a rotating lamp 12, and an RFID An informing unit cable for connecting the reader / writer 7, 14 a speaker as a warning means (informing unit), 15 an informing unit cable for connecting the speaker 14 and the RFID reader / writer 7, and 16 for entering and leaving the management area A passer-by such as a person or a guest, 17 is an RFID tag (IC card) possessed by the passer-by 16. Similar to the antenna unit 5 (antenna units 5a to 5j), the RFID tag 17 is a radio wave system using the UHF band or millimeter wave band or an electromagnetic induction system using the HF band in the path-restricted RFID tag system according to the present invention. It is possible to use an RFID tag or an IC card using various communication methods such as. In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted.

  1 and 2, it can be seen that the management area 1 that is a passage is partitioned by the management areas 2 to 5 that are all living rooms and the security door 3, but the route restriction system according to the first embodiment is a building. It is possible to apply even if it is not a building of the structure of 1. For example, there may be a case where there is no passage and all management areas are composed of living rooms, or a case where there is a passage but there is a living room that does not face the passage. Needless to say, the present invention can be applied not only to a building but also to an outdoor space such as a factory or school facility, and can be applied both indoors and outdoors. In such a case, a flapper gate may be used as the area partitioning means in addition to the security door. Moreover, it is not necessary to provide the security door 3 in a living room like the toilet partitioned by the door 3j shown in FIGS. In FIGS. 1 and 2, the door 3 j is unlocked and connected to the communication control unit 2 via the cable 8. Therefore, the door 3j is unlocked by the communication control unit 2 reading the tag ID of the RFID tag 17 via the antenna unit 5j installed in the vicinity of the door 3j. If the tag ID of the official RFID tag 17 is authenticated without performing the passage permission or the passage prohibition authentication based on the tag ID, the door 3j is opened. Lock it.

  The security door 3 and the structure accompanying this will be described with reference to FIGS. In addition, FIGS. 1 and 2 may be used for explanation. In FIG. 3A, the management area is partitioned by two security doors 3, and the antenna unit 5 is installed above each. When the passerby 16 enters the RFID tag reading area 4 of the antenna unit 5, the communication control unit 2 authenticates the tag ID, and if the tag ID is permitted to pass according to the content of the tag ID, the communication control unit 2 unlocks the security door 3. Next, FIG. 3B shows by dotted lines that the antenna unit 5 is also installed inside the security door 3. Thus, by installing the antenna unit 5 inside and outside the security door 3, it is possible to authenticate the tag ID of the RFID tag 17 inside and outside the security door 3. )can do. If the RFID tag reading area 4 can be formed inside and outside the security door 3 with only one antenna unit 5, the antenna unit 5 may be installed only on one side of the security door 3, but in that case, a passerby It is necessary to detect 16 traveling directions. In addition, when only one-way passage permission or no-pass authentication is performed for any tag ID, the antenna unit 5 may be installed only on one side of the security door 3. For this reason, the illustration of the antenna unit 5 in the management area is omitted in drawings other than FIG. If the area is partitioned by only one area partitioning means 3 as in the management area 5 (design room), one security is not provided, instead of the two security doors 3 shown in FIGS. Although only the door 3 is set, setting the passage permission of the two-way passage permission or the passage prohibition condition to the security door 3 is the same as the other management areas.

  In FIG. 3, the management area is described as a management area divided by two security doors 3 without specifying the management area. However, in FIG. 4, the management area is specified as the management area 2 (exhibition room), and further communication control is performed. A configuration in which the unit 2 includes the server 6 and the RFID reader / writer 7 will be described, but there is no difference in the essential configuration. FIG. 4A shows a state in which the management area 2 is partitioned by the security door 3c and the security door 3d. The antenna unit 5 c and the antenna unit 5 d are connected to the RFID reader / writer 7 through a coaxial cable 10, and the RFID reader / writer 7 is connected to the server 6 through a LAN cable 9. As shown in FIG. 4A, by dividing the function of the communication control unit 2 into the server 6 and the RFID reader / writer 7, the RFID reader / writer 7 is installed in the vicinity of each security door 3 (area partition means 3). As a result, not only the maintainability of each security door 3 is improved, but if a path restriction list described later is acquired from the server 6 or from the outside, the RFID reader / writer 7 and the security door 3 (in FIG. 4, the security door 3c The tag ID can be authenticated only in the closed network between the security door 3d) and the security door 3d).

  FIG. 4B shows a configuration near the security door in which a notification unit and warning means are added to the configuration near the security door shown in FIG. Further, the management area to be targeted is management area 3 (office). 4 (a) and 4 (b), there is no difference in the essential configuration. The display unit 11 and the rotating lamp 12 are connected to the RFID reader / writer 7 via the notification unit cable 13 in the security door 3e. The display unit 11 and the rotating lamp 12 function as a notification unit that notifies the tag ID authentication result. The display unit 11 may be a screen such as a liquid crystal display that displays a tag ID authentication result, or may be a light emitting element such as an LED. The display unit 11 may display “OK” if the passage is permitted, “NG” or the like if the passage is not allowed (the display of “OK” is illustrated in FIG. 4B). When the display unit 11 uses light emitting elements and the number of light emitting elements is small, the tag ID authentication result is changed to the lighting color of the light emitting element, the light emitting element is blinked, the traffic is permitted or not permitted. Notification may be made by, for example, turning on the corresponding light emitting elements.

  The display unit 11 not only displays “OK” or the like even when the passage is permitted, but also displays whether the tag ID that is permitted to pass has a one-way passage restriction on the security door. May be. With one-way traffic, the tag ID is authenticated, and it is possible to enter the adjacent management area through the security door, but there is authentication of permission to pass from the previous management area to the previous management area. It means not going down. Specifically, although it is possible to enter the management area 2 (exhibition room) from the management area 1 (passage) via the security door 3c, the management area 1 (passageway) from the management area 2 (exhibition room) via the security door 3c. ) May not enter the room (cannot leave the management area 2). In addition, even if it is impossible to pass, if one can enter the room from the opposite side of the security door, the one-way passage in that sense may be notified by the display unit 11. In this case, it is only necessary to prepare two types of one-way display such as one-way (permitted passage), one-way (not permitted), and the like. Of course, when there is no such traffic restriction, the display unit 11 may display that there is no traffic restriction by displaying that the traffic is bidirectional. Thus, since the passerby 16 can be informed in advance of the presence or absence of traffic restrictions, the possibility that the passerby 16 gets lost in the management area is also reduced. Further, as with the display unit 11, the revolving lamp 12 may be displayed as being lit if it is permitted to pass, or not lit if it is not allowed to pass (in FIG. However, in addition to turning on the light, it may be notified that the traffic is permitted or not allowed by blinking or turning off, but in the case of turning off, it is necessary to turn on in advance, but it remains turned off. This is not the case if this is a notification.) The one-way traffic restriction may be similarly notified by the rotating lamp 12. In that case, in order to identify two-way traffic, one-way traffic, and impassability, three types of notification patterns may be decided in advance by turning on, blinking, and turning off. The same applies to the display unit 11, and three types of display patterns may be set in advance in order to identify two-way traffic, one-way traffic, and impassability. In addition, when three types of notification patterns (display patterns) are displayed (notified) by dividing one-way into one-way (pass-permitted) and one-way (not-permitted), there are four types of notification patterns (display patterns). Will increase. In other words, it is only necessary to prepare notification patterns (display patterns) for the types to be notified. Further, the display unit 11 and the rotating lamp 12 may notify the warning by light or display when the result of the tag ID authentication is impassable.

  Subsequently, a speaker 14 is connected to the RFID reader / writer 7 via a notification unit cable 15 in the security door 3 f illustrated in FIG. The speaker 14 functions as a notification unit that notifies the authentication result of the tag ID, like the display unit 11 and the rotating lamp 12 described above. The speaker 14 only needs to notify the authentication result of the tag ID by voice or sound. If the passage is permitted, “OK indicating melody” may be transmitted, and if the passage is not permitted, “NG indicating melody” may be transmitted. It is conceivable (FIG. 4 (b) shows a state where an exemplary voice or sound (melody) is flowing). Of course, like the display unit 11 and the rotating lamp 12, the speaker 14 may notify that there is a one-way passage restriction described above. The speaker 14 may notify the warning by voice or sound when the tag ID authentication result is impassable. That is, when the display unit 11, the rotating lamp 12, and the speaker 14, which are notification units, are used as the warning unit, the warning is displayed when the tag ID authentication result is impassable. It will be notified by light or sound emitted from or light and sound. Moreover, the display part 11, the revolving light 12, and the speaker 14 illustrated in FIG. 4B may be used in combination with each security door 3, or may be used individually. Furthermore, the display unit 11, the rotating lamp 12, and the speaker 14 illustrated in FIG. 4B may be configured as an integrated device. The informing means and the number thereof selected for the combination of integration are arbitrary.

  Next, the relationship between the management areas will be described with reference to FIGS. 3 and 4, the communication control unit 2 and one management area are connected and managed. However, as shown in FIGS. 1 and 2, the communication control unit 2 actually has the management area 1. It is tied to ~ 5 and is managed. One RFID reader / writer 7 may be installed and managed for a plurality of management areas, or one RFID reader / writer 7 may be installed for each management area and a plurality of management areas. You may provide with an installation location. Specifically, as shown in FIG. 5, an RFID reader / writer 7 may be installed for each management area, and authentication of passage permission or passage prohibition may be performed. As shown in FIG. For example, one RFID reader / writer 7 may be installed to permit passage permission or to prohibit passage. 5 and 6 illustrate the management area 2 and the management area 3, the same configuration of the communication control unit 2 can be applied to the other management areas 1, 4, and 5. .

  Finally, the operation of the route-restricted RFID system according to the first embodiment will be described with reference to FIGS. In general operation, among the plurality of area partitioning means 3, there are a plurality of management areas partitioned by at least one area partitioning means, and the plurality of management areas are adjacent to each other via the area partitioning means 3. For each of the two management areas, the communication control unit 2 performs, for each tag ID, authentication for permission to pass, or prohibition of passage where the two management areas are one-way or two-way traffic. Description will be made using a management area 1 (passage) and a management area 2 (exhibition room) in the building 1 shown in FIGS. As an example, the security preset items for the management area 1 and the management area 2 are as follows. When the passer 16 is a related person, it is assumed that the tag ID of the RFID tag 17 possessed by the passer 16 is permitted to pass in both directions of the security door 3c and the security door 3d in the management area 2. When the passer-by 16 is a guest, the tag ID of the RFID tag 17 possessed by the passer-by 16 is assumed to be permitted to pass one-way through the security door 3c and the security door 3d in the management area 2. Specifically, the tag ID of the RFID tag 17 held by the guest is allowed to enter the management area 2 from the management area 1 that is a passage through the security door 3c, but from the management area 2 to the security door 3c. It is not permitted to leave the management area 1 that is a passageway, and the tag ID of the RFID tag 17 held by the guest is the management area 1 that is a passageway from the management area 2 to the security door 3d. However, it is not permitted to enter the management area 2 beyond the security door 3d from the management area 1 which is a passage.

  Based on the above preset items, the route-restricted RFID system according to the first embodiment will be specifically described. When a person in the management area 1 enters the RFID tag reading area 4 of the antenna unit 5c installed in the security door 3c, a radio wave (question wave) for confirming the tag ID from the antenna unit 5c controlled by the communication control unit 2 Is transmitted to the RFID tag reading area 4, and the RFID tag 17 held by the person who has received the interrogation wave transmits a reply wave with its tag ID as information to the antenna unit 5c. The antenna unit 5 c that has received the reply wave transmits the received signal to the communication control unit 2. The communication control unit 2 extracts the tag ID from the received signal derived from the return wave from the RFID tag 17 and authenticates that it is the ID (tag ID) of the person concerned, and then issues an unlocking instruction to the security door 3c. After the related person has entered the management area 2, the security door 3c is instructed to lock. When a related person leaves the management area 2 and heads toward the management area 1, the communication control unit 2 manages the security door 3 to select either the security door 3c or the security door 3d. The same processing as when entering the management area 2 from the area 1 is performed.

  When a guest in the management area 1 enters the RFID tag reading area 4 of the antenna unit 5c installed in the security door 3c, a radio wave (question wave) for confirming the tag ID is received from the antenna unit 5c controlled by the communication control unit 2. The RFID tag 17 transmitted to the RFID tag reading area 4 and held by the guest who has received the interrogation wave transmits a reply wave having its tag ID as information to the antenna unit 5c. The antenna unit 5 c that has received the reply wave transmits the received signal to the communication control unit 2. The communication control unit 2 extracts the tag ID from the received signal derived from the return wave from the RFID tag 17 and authenticates the guest ID (tag ID), and then issues an unlocking instruction to the security door 3c. After the guest has entered the management area 2, the security door 3c is instructed to lock.

  When the guest leaves the management area 2 and intends to go to the management area 1, if the security door 3 selected for leaving is the security door 3c, the RFID of the antenna unit 5c installed in the security door 3c When entering the tag reading area 4, a radio wave (interrogation wave) for confirming the tag ID is transmitted from the antenna unit 5c controlled by the communication control unit 2 to the RFID tag reading area 4, and the RFID held by the guest who has received the interrogation wave The tag 17 transmits a reply wave with its tag ID as information to the antenna unit 5c. The antenna unit 5 c that has received the reply wave transmits the received signal to the communication control unit 2. The communication control unit 2 extracts the tag ID from the received signal derived from the return wave from the RFID tag 17 and authenticates that it is the guest ID (tag ID). Since the authentication is impossible, the communication control unit 2 opens the security door 3c. Do not give instructions for locks. When it is necessary to inform the guest that the security door 3 is not accessible, the display unit 11, the revolving light 12, and the speaker 14 are installed on the security door (in this case, the security door 3c) and cannot pass. To the guest. In some cases, a guest may be notified by a notification means that the security door 3 that can be removed is the security door 3d.

  When the guest leaves the management area 2 and intends to go to the management area 1, if the security door 3 selected to leave is the security door 3d, the RFID of the antenna unit 5d installed in the security door 3d When entering the tag reading area 4, a radio wave (question wave) for confirming the tag ID is transmitted from the antenna unit 5d controlled by the communication control unit 2 to the RFID tag reading area 4, and the RFID held by the guest who has received the interrogation wave The tag 17 transmits a reply wave with its tag ID as information to the antenna unit 5d. The antenna unit 5 d that has received the reply wave transmits the received signal to the communication control unit 2. The communication control unit 2 takes out the tag ID from the received signal derived from the return wave from the RFID tag 17, authenticates that it is the guest ID (tag ID), and then issues an unlocking instruction to the security door 3d. After the guest has left the management area 1, the security door 3d is instructed to lock.

  When a guest in the management area 1 enters the RFID tag reading area 4 of the antenna unit 5d installed in the security door 3d, a radio wave (question wave) for confirming the tag ID is received from the antenna unit 5d controlled by the communication control unit 2. The RFID tag 17 transmitted to the RFID tag reading area 4 and held by the guest who has received the interrogation wave transmits a reply wave with its own tag ID as information to the antenna unit 5d. The antenna unit 5 d that has received the reply wave transmits the received signal to the communication control unit 2. The communication control unit 2 extracts the tag ID from the received signal derived from the return wave from the RFID tag 17 and authenticates that it is the guest ID (tag ID). Since the authentication cannot be performed, the communication control unit 2 opens the security door 3d. Do not give instructions for locks. When it is necessary to notify that it is not the security door 3 that can enter the guest, the display unit 11, the revolving light 12, and the speaker 14 are installed on the security door (in this case, the security door 3d) and cannot pass. To the guest. In some cases, a guest may be notified by a notification means that the security door 3 that can be entered is the security door 3c.

  By performing the processing as described above in the management areas 1 to 5, it is possible to easily limit the route for each tag ID of the RFID tag in the entrance / exit system using RFID. In other words, for every two adjacent management areas in the management areas 1 to 5, authentication for permission to pass, or authentication for prohibition of passage, in which the two management areas are one-way or two-way traffic, is communicated for each tag ID. The control part 2 should just do. Of course, even if it is partitioned by only one area partitioning means 3 as in the management area 5 (design room), it is the same as other management areas. In addition, authentication for each tag ID in two adjacent management areas can be easily performed if the communication control unit 2 performs the authentication based on the path restriction list set for each tag ID. If the route restriction list is set such that one-way permission or two-way permission is permitted every predetermined time, or a condition in which the passage prohibition is changed for each management area, the display of the management area 2 that is an exhibition room is displayed. In the management area 4 which is a dining room that allows guests to enter and leave the room according to time, the entrance and exit (entrance: security door 3g, Exit: The security door 3h) is limited to one-way traffic, and it can be easily set to bidirectional traffic when it is not crowded. Of course, it is possible to set the route restriction list so that the one-way permission or two-way passage permission or the passage prohibition condition is changed for each management area every predetermined time. It goes without saying that can be set for each day of the week. Note that each day of the week does not simply indicate every 24 hours, but indicates that the direction of traffic and the permitted / inaccessible traffic differ for each day of the week, and the route restriction list is changed exactly every 24 hours. It doesn't just mean that.

  From the building 1 when the passerby 16 (related person or guest) enters the management area 1 to 5 or exits the room (only when entering the management area different from the room being exited). If the route restriction list is changed, the passer 16 (related person or guest) may be present at that time, depending on the direction of traffic and the permission / non-permission settings. In such a case, when the communication control unit 2 changes the route restriction list after the tag ID is authenticated, the communication tag after the authenticated tag ID is changed. Authentication is performed based on the route restriction list before the change or when the route restriction list is changed after the tag ID is authenticated, the subsequent authentication of the authenticated tag ID is passed through. While returning to the area It may be performed only the authentication of the line. That is, a route restriction list in which such route restriction is set may be prepared.

  When there are many passersby 16 (related persons and guests) and it is complicated to set permission for one-way or two-way traffic between two management areas, or prohibition of traffic for each tag ID In consideration of the security of the building 1, the tag ID is classified into a predetermined number of tag levels according to the security level of the assumed passer 16, and the two management areas are one-way between the tag levels. You may set the passage permission which is a two-way passage, or a passage prohibition. This tag level may be added to the tag ID of the RFID tag 17 and stored (recorded) in a memory in the RFID tag, or the tag ID may be stored on the communication control unit 2 (server 6 or RFID reader 7) side. And tag level may be associated with each other and managed. That is, when linking, the communication control unit 2 acquires the tag ID of the RFID tag 17 held by the passerby 16 via the antenna unit 5, and searches for the tag level where the tag ID is classified.

Embodiment 2. FIG.
In the first embodiment, the detailed setting for each management area is not illustrated with respect to the route restriction list, but in the second embodiment, regarding the operation of the route restriction RFDID system when the detailed setting for each management area is performed, This will be described in more detail. In the second embodiment, the route restriction list will be described as an entry / exit restriction information table in which details regarding the building 1 are described. Accordingly, the basic configuration and operation of the path-restricted RFID system according to the first and second embodiments are common, and therefore, the second embodiment may not be described again. A second embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a diagram showing an example of the tag level of the RFID tag described in the first embodiment, and FIGS. 8 and 10 are diagrams showing an entrance / exit restriction information table, which are described in the door ID column in the figure (in the table). A to I indicate door A (security door 3a) to door I (security door 3i). FIGS. 9 and 11 are flowcharts showing the flow for determining whether to enter or leave the room. The entrance / exit determination is performed for each tag ID (for each tag level) by the communication control unit 2 of the route-restricted RFID system according to the first embodiment. In this case, the authentication indicates permission of passage permitting or one-way passage between the two management areas, or authentication prohibition of passage. In the figure (in the flowchart), the warning is to issue a warning by warning means. The basic configuration and operation are the same as those described with reference to FIGS. 1 to 6, and accordingly, when necessary for the description of the second embodiment, FIGS. Sometimes.

  Next, the operation of the route-restricted RFID system according to the second embodiment will be described. FIG. 7 is a diagram illustrating an example of a tag level table of the RFID tag 17 (tag ID) used in the route-restricted RFID system according to the second embodiment, in which a group of passers-by 16 is set for each security level. It is. FIG. 8 is an example of a table of the security door 3 including the entrance / exit restriction information in the second embodiment. In order to manage which security level (tag level) tag can be entered / exited for each door (security door 3), an entry / exit restriction information table (route restriction list) as shown in FIGS. ) Is held by the communication control unit 2. In FIG. 8, the system administrator of the route-restricted RFID system can arbitrarily change the setting of the entrance / exit restriction information, and is set when traffic in a certain time zone is dynamically restricted. FIG. 9 is a flowchart showing a flow of determining whether to enter or leave the room according to the first embodiment, and (S1A) to (S11A) in the figure are ellipsis indicating steps in the flowchart. When a passerby 16 carrying the RFID tag 17 stands in front of the security door 3 on which the antenna unit 5 of the building 1 is installed, the antenna unit 5 reads information of the RFID tag 17 and is wired to the server 6 by the RFID reader / writer 7. Or it is transmitted by radio.

  Upon receiving the information of the RFID tag 17 transmitted from the RFID reader / writer 7 (S1A), the server 6 acquires the current date and time (S2A), and based on the transmitted information, the ID of the security door 3 and the direction of travel ( The ID of the security door 3 may be an ID set for each security door 3, or may be substituted by setting an ID for each antenna unit 5 or for each RFID reader / writer 7. A plurality of RFID readers / writers 7 may have a plurality of IDs. When managing the security door 3, it is needless to say that the ID set for each RFID reader / writer 7 may not be used in place of the information. And the entry / exit restriction information is obtained from the corresponding table of the security door (S3A). Further, the communication control unit 2 identifies the passerby 16 from the received tag ID (tag level) of the RFID tag 17 and acquires the security level of the RFID tag 17 (S4).

  Further, the server 6 compares the security level of the acquired entry / exit restriction information with the tag level to determine whether or not the tag level is equal to or higher than the door security level (S5A). If the tag level is equal to or higher than the security level of the security door, it is determined whether or not it is possible to pass in the direction of the reading unit that has read the tag ID (S6A). If the date and time when the RFID tag 17 is received is not the allowed passage time, it is determined whether or not the passage is permitted even during the unavailable time (S7A). When the date and time when the RFID tag 17 is received is a passable time, and when the pass is permitted even during an inoperable time, it is determined whether or not the day of the week when the tag is received is a passable day. (S8A). If the day of the week when the RFID tag 17 is received is not a passable day, it is determined whether entry / exit is permitted even if the day is not available (S9A). If the day of the week when the RFID tag 17 is received is permitted to pass, and if entry / exit is permitted even if it is an impossible day, it is determined that entry / exit is permitted, and the door is displayed by unlocking and display ( After S10A), the determination process of the server 6 is terminated. Note that these determination processes may be executed by the RFID reader / writer 7. If entry / exit is not permitted by each determination, a warning is issued by any one of the display unit 11, the rotating lamp 12, the speaker 14, or a combination thereof as notification means (warning means) (S 11 A), and determination processing Exit.

  As an operation example, attention is paid to the dining room entrance of the security door 3g described in FIGS. Since the security door 3g is at the security level 1, all tag owners pass through the security door 3g from the management area 1 (passage) to the management area 4 (canteen), and from the management area 4 (canteen) to the management area 1 ( Passage to the aisle) is allowed, but the allowed entry time is 0:00 to 24:00 and the leaving direction is 14:00 to 21:00. Since the tag level is not set in either the entry / exit direction, the user can only enter the room until 14:00 and cannot leave the room. From 14:00 to 21:00, both entrance and exit are possible.

  According to the route-restricted RFID system according to the second embodiment, by setting an entry / exit restriction information table (route restriction list) for each security door, entry / exit by one-way restriction, time zone restriction, day-of-week restriction. Management becomes possible. In addition, it is possible to restrict one-way traffic in a time zone, such as making an arbitrary door one-way only in an arbitrary time zone. Furthermore, it is not necessary to create a route table in order to implement one-way restriction, so that entry / exit restriction information can be set flexibly and easily.

  FIG. 10 is an example (modification) of a door table including entry / exit restriction information in the route-restricted RFID system according to the second embodiment. Similarly to FIG. 8, the setting of the entry / exit restriction information can be arbitrarily changed by the system administrator of the route restriction RFID system according to the second embodiment. FIG. 11 is a flowchart showing a flow of determining whether to enter or leave the room in this embodiment, and (S1B) to (S13B) in the figure are ellipsis indicating steps in the flowchart. Since (S1B) to (S5B) are the same as (S1A) to (S5A) in the second embodiment, description will be made from (S6B).

  If the tag level is equal to or higher than the security level of the security door 3, it is determined whether or not the RFID reader / writer 3 that has transmitted the tag information is in a direction in which the entrance / exit restriction information can pass (S6B). If it is not in the passable direction, it is determined whether entry / exit is permitted even from the impossible direction (S7B). If the RFID reader / writer 3 that has transmitted the tag information is in the passable direction, and if entry / exit is permitted even in the impossible direction, whether the date and time when the RFID tag 17 is received is the passable time or not Is determined (S8B). If the date and time when the RFID tag 17 is received is not allowed to pass, it is determined whether entry / exit is permitted even during the unavailable time (S9B). Whether the date and time when the RFID tag 17 is received is allowed to pass, and if entry / exit is permitted even during the unavailable time, whether or not the day of the week when the RFID tag 17 is received is allowed to pass Is determined (S10B). If the day of the week when the RFID tag 17 is received is not a passable day, it is determined whether entry / exit is permitted even if the day is not a passable day (S11B). If the day of the week when the RFID tag 17 is received is permitted to pass, and if entry / exit is permitted even if it is an impossible day, it is determined that entry / exit is permitted, and the door is displayed by unlocking and display ( After S12B), the determination process of the server 6 is terminated. Note that these determination processes may be executed by the RFID reader / writer 7. If entry / exit is not permitted by each determination, a warning is issued by any one of the display unit 11, the rotating lamp 12, the speaker 14, or a combination thereof as a notification unit (warning unit) (S 13 B), and determination processing Exit.

  According to the modified example of the second embodiment, by setting the entry / exit restriction information table (route restriction list) in the security door 3, entrance / exit management by one-way restriction, time zone restriction, day-of-week restriction is performed. It becomes possible. In addition, it is not necessary to create a route table in order to perform one-way restriction, and each restriction is different, and therefore, entry / exit restriction setting work is easier than in the second embodiment.

  As described above, in the path-restricted RFID system according to the second embodiment, the communication control unit 2 (server 6, RFID reader / writer 7) is the area partition unit 3 set for each date and each tag level. Is provided with a route restriction list for setting information that permits or prohibits passage, and a reply wave having tag ID information from the RFID tag 17 with respect to the interrogation wave from the antenna unit 5 is controlled via the antenna unit 5 The current date and time acquisition means for acquiring the acquisition date and time of the tag ID when sent to the section 2, and the area partitioning means 3 set for each tag level at the date and time acquired by the current date and time acquisition means Alternatively, a traffic direction acquisition unit that acquires information on improper passage from the route restriction list, tag information that acquires tag level that is tag information from tag ID information The acquisition means, the tag level acquired by the tag information acquisition means and the information set for each tag level acquired by the traffic direction acquisition means, and the tag level acquired by the tag information acquisition means , And a traffic determination means for determining whether the traffic falls under any of the following conditions.

  The subsequent stage of the current date acquisition means may have the following configuration. The area partitioning means 3 set for each tag level obtains tag information that is tag information from the information of the tag ID from the traffic direction obtaining means that obtains the passage permission information or the information that the passage is impossible from the route restriction list. The tag information acquisition unit obtains the current date and time acquired by the current date and time acquisition unit by comparing the tag level acquired by the tag information acquisition unit and the information set for each tag level acquired by the traffic direction acquisition unit. A traffic determination unit that determines whether the tag level corresponds to traffic permission or traffic prohibition may be used. Note that the above two types of passage direction acquisition means are, for example, the direction of passage from the management area 1 (passage) to the management area 2 (exhibition room), or from the management area 2 (exhibition room) to the management area 1 (passage). ) Is a means for determining by specifying the antenna unit 5 that has received the tag ID (reply wave). If the antenna unit 5c installed outside the security door 3c receives the tag ID, the direction is the direction from the management area 1 (passage) to the management area 2 (exhibition room), and inside the security door 3c. When the installed antenna unit 5c receives the tag ID, the direction is the direction from the management area 2 (exhibition room) to the management area 1 (passage).

In FIG. 8, when the passable day of the week and the no-passage passable tag level are deleted, one-way passage of an arbitrary door is possible only in an arbitrary time zone when no day-by-day traffic restriction is performed. In FIG. 10, if the passable day and non-passable tag levels are deleted, one-way restriction and time-of-day restriction can be easily performed when the day-by-day restriction is not performed.

  In FIG. 10, if the passable time zone and the unavailable time passable tag level are deleted, the one-way pass restriction and the day-by-day pass restriction can be easily performed when the time zone pass restriction is not performed. In FIG. 10, when the passable direction and non-passable passable tag levels are deleted, the time zone pass restriction and the day-by-day pass restriction can be easily performed when the one-way restriction is not performed. In FIG. 10, when the passable time zone and the restricted-time passable tag level and the passable weekday and disabled-day passable tag level are deleted, the one-way restriction can be easily performed when only the one-way restriction is performed. .

  In FIG. 10, when the passable / impossible passable tag level and the passable / non-passable tag level are deleted, the time zone pass restriction can be easily performed when only the time pass restriction is performed. Become. In FIG. 10, by deleting the passable / impossible passable tag level, the passable time zone, and the nonpassable passable tag level, the day-by-day pass restriction can be easily implemented when only the day-of-week pass restriction is performed. It becomes.
