Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an entrance / exit management system and an entrance / exit management method for reading out identification information written on a recording medium such as an IC card in a research facility, etc., determining whether or not the vehicle is illegally passed, and restricting entrance / exit. Is.
[0002]
[Prior art]
[Conventional example 1: Center batch control method]
Conventionally, as this type of entrance / exit management system, there is an entrance / exit management system that employs a central control system. FIG. 9 shows a main part of an entrance / exit management system that employs the center collective control method. In the figure, 1-1 to 1-4 are readers arranged at the entrance to the room, 2 is a management device provided in the central monitoring room, 3 is a reader 1-1 to 1-4 and the management device 2 Is a communication line to connect.
[0003]
In this example, the reader 1-1 is provided at the entrance from the indoor compartment (1) to the indoor compartment (2), and the reader 1-2 is provided at the exit from the indoor compartment (2) to the indoor compartment (1). It has been. The reader 1-3 is provided at the entrance from the indoor compartment (3) to the indoor compartment (4), and the reader 1-4 is provided at the exit from the indoor compartment (4) to the indoor compartment (3).
[0004]
In this entrance / exit management system, when entering the room compartment (2) from the room compartment (1), the person entering the room sets the IC card 4 in which identification information (for example, a card number) is written in the reader 1-1. . The reader 1-1 reads the identification information written in the set IC card 4, and sends the identification information and unique information (for example, a management code number) of the reader 1-1 to the management device 2 via the communication line 3. Send to.
[0005]
[Normal entry / exit control]
Based on the identification information and unique information from the reader 1-1, the management device 2 determines whether or not the person who holds the IC card 4 is a person who is permitted to enter the room section (2). If the person is permitted to enter the room, the reader 1-1 is informed of this, the entry permission display is displayed, and the electric lock (not shown) is unlocked, and the indoor compartment (1) to the indoor compartment (2). Open the door to ▼.
[0006]
[Anti-passback control]
In the normal entrance / exit control described above, if the IC card 4 is given to a third party outside the indoor compartment <2> by some method after entering the indoor compartment <2> from the indoor compartment <1>, the same control is performed. It is possible to illegally enter the indoor compartment {circle around (1)} from the indoor compartment {circle around (1)} by using the IC card 4 repeatedly, that is, by performing a continuous entry operation. It is also possible to enter the indoor compartment (4) from the indoor compartment (3) without performing the exit operation from the indoor compartment (2) to the indoor compartment (1). Therefore, the conventional entrance / exit management system performs anti-passback control.
[0007]
In the anti-passback control, the management device 2 stores the entry operation from the indoor compartment (1) to the indoor compartment (2) using the IC card 4, for example, from the indoor compartment (2) to the indoor compartment. Entry operation from room compartment (1) to room compartment (2) using the same IC card 4 again, even though the exit operation using IC card 4 to (1) is not performed If it is performed, it is regarded as illegal traffic, and entry into the indoor compartment (2) from the indoor compartment (1) is restricted. Further, for example, although the exit operation using the IC card 4 from the indoor compartment (2) to the indoor compartment (1) is not performed, the IC card 4 is used to move from the indoor compartment (3). When an entry operation to the indoor compartment (4) is performed, it is regarded as illegal traffic, and entry from the indoor compartment (3) to the indoor compartment (4) is restricted.
[0008]
In this way, the management device 2 determines various illegal traffics by the anti-bus back control, and restricts entry / exit. As an example of an entrance / exit control system employing such a central control system, there is an “entrance / exit management method and entrance / exit management system” disclosed in Japanese Patent Laid-Open No. 2000-259968.
[0009]
[Conventional example 2: Controller control method]
FIG. 10 shows a main part of an entrance / exit management system employing a conventional controller control system. In the figure, 1-1 to 1-8 are readers arranged at the entrance to the room, and 5-1 and 5-2 are control devices (controllers) distributed in the facility.
[0010]
In this example, the reader 1-1 is provided at the entrance from the indoor compartment (1) to the indoor compartment (2), and the reader 1-2 is provided at the exit from the indoor compartment (2) to the indoor compartment (1). It has been. The reader 1-3 is provided at the entrance from the indoor compartment (3) to the indoor compartment (4), and the reader 1-4 is provided at the exit from the indoor compartment (4) to the indoor compartment (3).
The reader 1-5 is provided at the entrance from the indoor compartment (5) to the indoor compartment (6), and the reader 1-6 is provided at the exit from the indoor compartment (6) to the indoor compartment (5). Yes. The reader 1-7 is provided at the entrance from the indoor compartment (7) to the indoor compartment (8), and the reader 1-8 is provided at the exit from the indoor compartment (8) to the indoor compartment (7).
[0011]
The readers 1-1 to 1-4 are connected to the control device 5-1 as the first reader group 1A. The readers 1-5 to 1-8 are connected to the control device 5-2 as the second reader group 1B. The control device 5-1 sets the area where the reader group 1 </ b> A is installed as the management section S <b> 1, and manages the entrance / exit in the management section S <b> 1. The control device 5-2 sets the area where the reader 1B is installed as the management section S2, and manages the entrance / exit in the management section S2.
[0012]
In this entry / exit management system, when entering the room compartment (1) from the room compartment (1), the person entering the room sets the IC card 4 in the reader 1-1. The reader 1-1 reads the identification information written in the set IC card 4, and sends this identification information and unique information of the reader 1-1 to the control device 5-1.
[0013]
Based on the identification information and unique information from the reader 1-1, the control device 5-1 determines whether or not the person who has the IC card 4 is a person who is permitted to enter the room section (2). If the person is permitted to enter the room, the reader 1-1 is informed of this, the entry permission display is displayed, the electric lock (not shown) is unlocked, and the room compartment (1) is opened. Open the door to compartment (2).
[0014]
At this time, the control device 5-1 stores the entry operation from the indoor compartment (1) to the indoor compartment (2) using the IC card 4. Then, by the anti-passback control, for example, the same IC card 4 is again inserted even though the exit operation using the IC card 4 from the indoor compartment (2) to the indoor compartment (1) is not performed. When an entry operation from the indoor compartment (1) to the indoor compartment (2) is performed, it is regarded as illegal traffic and entry into the indoor compartment (2) from the indoor compartment (1) is restricted. Further, for example, although the exit operation using the IC card 4 from the indoor compartment (2) to the indoor compartment (1) is not performed, the indoor compartment (3) using the IC card 4 is used. When entering the room compartment (4) is considered to be unauthorized traffic, entry into the room compartment (4) from the room compartment (3) is restricted.
[0015]
As described above, the control device 5-1 determines various unauthorized passages in the management section S <b> 1 by anti-passback control, and restricts entrance and exit. Similarly to the control device 5-1, the control device 5-2 determines various illegal traffics in the management section S2 by anti-passback control, and restricts entry / exit. An example of an entrance / exit control system employing such a controller control method is an “anti-pass back-through system” disclosed in Japanese Patent Laid-Open No. 2000-276622.
[0016]
[Problems to be solved by the invention]
In the entrance / exit management system (conventional example 1) adopting the center collective control method shown in FIG. 9, the load is concentrated on the management device 2 and the management device 2 may be down. If the management apparatus 2 goes down, anti-passback control cannot be performed in all the facilities. In addition, since the management device 2 and the reader 1 in the facility are considerably separated from each other, there is a time delay until the identification information and unique information from the reader 1 is transmitted to the management device 2. The time required for collation including the communication time with the management apparatus 2 becomes longer.
[0017]
In contrast, in the entrance / exit management system (conventional example 2) employing the controller control method shown in FIG. 10, the load is distributed to the plurality of control devices 5. Even if one control device 5 goes down, the anti-passback control is continuously performed in the management section S managed by the other control device 5. Further, since the distance between the control device 5 and the reader 1 in the management section S of the control device 5 is short, there is little time delay until the identification information and unique information from the reader 1 is transmitted to the control device 5, The time required for verification including the communication time between the reader 1 and the control device 5 is shortened.
[0018]
Thus, the entrance / exit management system employing the controller control method has superior advantages (high-speed verification, load distribution, etc.) compared to the entrance / exit management system employing the center collective control method. However, since the control devices 5 independently manage entry / exit in the management section S, that is, there is no horizontal connection between the control devices 5, the IC card 4 that straddles the management section S of the control device 5 Could not cope with the use of. For example, when the IC card 4 used in the management section S1 is set in the reader 1-5 of the management section S2, the IC card 4 is illegally entered / exited in the management section S1 in the control device 5-2. It is impossible to know whether it is a thing or not, and it is not possible to determine whether it is unauthorized traffic.
[0019]
In addition, in the control device 5, for example, when maintenance is performed, there is a problem that the anti-passback control cannot be performed when information related to the entry / exit operation is lost. For example, in the management section S1, when the IC card 4 is set in the card reader 1-1 and enters the indoor section (2) from the indoor section (1), the control device 5-1 uses the IC card 4 The entry operation from the indoor compartment (1) to the indoor compartment (2) is stored. If the memory of this room entry operation disappears during maintenance, etc., this will be detected even if the room entry operation from room compartment (1) to room compartment (2) is performed again using the same IC card 4 Cannot be performed and anti-passback control is not performed.
[0020]
As a reader control method, a reader / writer that can be read / written is used instead of a reader, entry / exit information is written in an IC card set in the reader / writer, and anti-passback control is performed by the reader / writer. There is also a system. In this reader control type entrance / exit management system, there is no management section like the controller control type, and it is possible to cope with the use of IC cards in all facilities. In addition, information related to the entrance / exit operation cannot be lost during maintenance or the like. However, a reader-controlled entry / exit management system is expensive because a reader / writer is used. Further, since a time delay of reading / writing / verification (Verify) to the IC card occurs, the verification time becomes long.
[0021]
The present invention has been made to solve such a problem, and the object of the present invention is to manage the control section while inheriting the advantages such as high-speed verification and load distribution of the entrance / exit management system adopting the controller control method. Entry / exit management that can perform anti-passback control even when using recording media that straddles, and that can continue to perform anti-passback control even if information related to entry / exit operations is lost The object is to provide a system and an entrance / exit management method.
[0022]
[Means for Solving the Problems]
In order to achieve such an object, the first invention (the invention according to claim 1) is connected to at least one reader for reading identification information written on a recording medium moving between indoor compartments. Corresponding to the unique information, the installation position information that records the room compartment of the entry source and the entry destination determined by the installation position of the reader, and the current position of the recording medium corresponding to the identification information written on the recording medium The entrance / exit management system is provided with a plurality of control devices that hold the current position information recorded as the current compartment for each indoor compartment, and each control device is written to the recording medium via a reader connected to itself. Is read, the current section recorded in its current position information corresponding to the identification information is read and identified as the current section. The collation means for collating the room compartment of the entry source recorded in the installation position information corresponding to the unique information of the reader that has read the information, and the collation means make the current compartment and the room compartment of the entry room coincide with each other. If it is determined that the entry has been made, entry permission means for permitting entry from the room compartment of the entry source where the reader that has read the identification information is installed to the room compartment of the entry destination, and the current section and the room entry by the verification means If it is determined that the original room compartment matches, the current compartment corresponding to the identification information read from the recording medium recorded in the current current position information is set as the room compartment to which the entry is permitted. When it is determined by the current section rewriting means to be rewritten and the collating means that the current section and the room section of the entry source match, the other control apparatus Provided with a message transmission means for transmitting a message to rewrite the current section corresponding to the identification information read from the recording medium in the current position information possessed by the room section of the entry destination permitted to enter the room It is.
[0023]
In this invention, each control device has an installation position that records the room compartment of the entry source and the entry destination determined by the installation position of the reader corresponding to the unique information (for example, management code number) of the reader connected to itself. Information and current position information in which the indoor section where the recording medium is currently located is recorded as the current section corresponding to the identification information (for example, card number) written in the recording medium (for example, IC card). Is held.
When the control device reads the identification information written on the recording medium through a reader connected to the control device, the control device records a current section (hereinafter referred to as a recording) recorded in the current position information of the control device corresponding to the identification information. The current section of the recording medium) is read, and the current section of the recording medium is compared with the indoor section of the entry source recorded in the installation position information corresponding to the reader's unique information that has read the identification information.
If it is determined by this collation that the current section of the recording medium matches the room compartment of the entry source, that is, the room section where the recording medium will be currently located and the room compartment of the entry source coincide. If it is determined, the control device permits entry from the room compartment of the entry room where the reader that has read the identification information is installed to the room compartment of the entry destination.
In addition, when the control device determines that the current section of the recording medium and the room section of the entry source coincide with each other by the collation, the control apparatus permits entry of the current section of the recording medium recorded in its current position information. Rewrite the room compartment at the entrance. For example, if the current section of the recording medium recorded in the current position information of the self is (1) and the room section of the room where entry is permitted is (2), it is recorded in the current position information of the self. Rewrite the current section of the recording medium to (2).
In addition, when the control device determines that the current section of the recording medium and the room compartment of the entry source coincide with each other by the collation, the control device determines the current position information in the current position information held by the other control device to the other control device. A message is sent to the effect that the current section of the recording medium will be rewritten to the room section that is permitted to enter the room. As a result, also in other control apparatuses, the current section of the same recording medium in the current position information held by the control apparatus is rewritten to the room section of the entry destination permitted by the control apparatus that transmitted the message.
[0024]
Therefore, the current section of the recording medium is shared by all the control apparatuses that can use the recording medium, and anti-passback control is performed even when the recording medium is used across the control section of the control apparatus. Can be done.
In addition, even if the current section of the recording medium disappears in the control device, the other control device that can use the recording medium shares the current section of the recording medium. It is possible to restore the current partition that has been lost due to the shared current partition, and to continuously perform anti-passback control.
[0025]
The second invention (the invention according to claim 2) is connected to at least one reader for reading the identification information written on the recording medium moving between the indoor compartments, and corresponds to the reader's unique information. Corresponding to the installation position information that records the room compartment of the entry source and the entry destination determined by the installation position and the identification information written in the recording medium, the indoor compartment where the recording medium is currently located is recorded as the current section. A plurality of control devices that hold current position information, and installation positions that record room compartments of entry and entry destinations determined by the installation positions of the readers corresponding to the specific information of the readers connected to these control devices Corresponding to the management information and the identification information written on the recording medium, the indoor section where the recording medium is currently located is recorded as the current section. When the identification information written on the recording medium is read by the control device via the reader connected to the control device, the identification information is obtained. The current section recorded in the current position information of the reader corresponding to the current section, and the room of the entry source recorded in the installation position information of the reader corresponding to the unique information of the reader that read the current section and the identification information When the collating means for collating the section and the collating means determine that the current section and the room compartment of the entry source are the same, from the room compartment of the entry room where the reader that has read the identification information is installed If it is determined by the collation means that the current compartment and the room compartment of the entry source match, the entrance permission means for permitting entry into the indoor compartment of the entry destination Current section rewriting means for rewriting the current section corresponding to the identification information read from the recording medium recorded in the current position information to the room section at the entry destination permitted to enter, and the collating means When it is determined that the original indoor section matches, the current position information and the current position management information held by the other control device and management device are transferred to the other control device and management device from the recording medium. Message transmitting means is provided for transmitting a message to rewrite the current section corresponding to the read identification information to the room section that is permitted to enter the room.
[0026]
In this invention, each control device has an installation position that records the room compartment of the entry source and the entry destination determined by the installation position of the reader corresponding to the unique information (for example, management code number) of the reader connected to itself. The indoor compartment where the recording medium is currently located corresponding to the information and identification information (eg, card number) written in the recording medium (eg, IC card) that can be used in its own management compartment Holds the current position information recorded as the current section.
In addition, the management device is connected to these control devices and is written in a recording medium and installation position management information that records the room compartment of the entry source and the entry destination determined by the installation position of the reader corresponding to the unique information of the reader. Corresponding to the identification information, the indoor section where the recording medium is currently located holds current position management information recorded as the current section.
When the control device reads the identification information written on the recording medium via a reader connected to itself, the control device corresponds to the identification information and the current section (recording medium of the recording medium) recorded in its current position information. Current section) is read, and the current section of the recording medium is compared with the room section of the entry source recorded in the installation position information corresponding to the unique information of the reader that has read the identification information.
If it is determined by this collation that the current section of the recording medium matches the room compartment of the entry source, that is, the room section where the recording medium will be currently located and the room compartment of the entry source coincide. If it is determined, the control device permits entry from the room compartment of the entry room where the reader that has read the identification information is installed to the room compartment of the entry destination.
In addition, when the control device determines that the current section of the recording medium and the room section of the entry source coincide with each other by the collation, the control apparatus permits entry of the current section of the recording medium recorded in its current position information. Rewrite the room compartment at the entrance. For example, if the current section of the recording medium recorded in the current position information of the self is (1) and the room section of the room where entry is permitted is (2), it is recorded in the current position information of the self. Let {2} be the current section of the recording medium.
In addition, when the control device determines that the current section of the recording medium and the room compartment of the entry source coincide with each other by the collation, the other control device and the management device hold the other control device and the management device. A message to rewrite the current section of the recording medium in the current position information and the current position management information to the room section of the entry destination permitted to enter the room is transmitted. As a result, also in other control apparatuses, the current section of the same recording medium in the current position information held by the control apparatus is rewritten to the room section of the entry destination permitted by the control apparatus that transmitted the message. Also in the management apparatus, the current section of the same recording medium in the current position information held by the management apparatus is rewritten to the room section of the entry destination permitted by the control apparatus that transmitted the message.
[0027]
Therefore, the current section of the recording medium is shared by all the control apparatuses that can use the recording medium, and anti-passback control is performed even when the recording medium is used across the control section of the control apparatus. Can be done.
Even if the current section of the recording medium disappears in the control device, other control devices and management devices that can use the recording medium share the current section of the recording medium. It is possible to restore the current partition that has been lost by the current partition shared by the control device and the management device, and to continuously perform the anti-passback control.
In this case, since the other control apparatus shares only the current section of the recording medium that can be used in the management section of the control apparatus, the current section may not be completely recovered. On the other hand, since the management apparatus shares the current section of the recording medium that can be used by all the management sections including the management section of the control device, the current section can be completely recovered.
[0028]
According to a third invention (invention according to claim 3), in the second invention, when the control device further determines that the current compartment and the indoor compartment of the entry source do not coincide with each other by the collating means, the management device Reconfirmation request means for requesting the return of the current section recorded corresponding to the identification information read from the recording medium in the current position management information possessed by the management apparatus, and a request from this reconfirmation request means Responding to re-verify the current section returned from the management device and the room section of the entry source recorded in its own installation position information corresponding to the unique information of the reader that read the identification information from the recording medium Means.
[0029]
In the present invention, the control device normally performs verification (primary verification) without inquiring of the management device, but the identification read from the recording medium only when it is determined that there is a mismatch (anti-passback NG) by this verification. In response to the information, the management apparatus is requested to return the current section recorded in the current position management information, and the management apparatus performs re-collation (secondary collation) using the returned current section.
[0030]
When a part or all of the current section in the current position information of the control device is lost during maintenance or the like, secondary collation is performed because it is determined that the primary collation does not match. When it is determined to be coincident by the secondary collation, the control device rewrites the current section of the recording medium recorded in its current position information to the room section of the entry destination permitted to enter. Thus, in the third invention, even if a part or all of the current section in the current position information of the control device is lost, the disappearance is automatically performed by the current section returned from the management apparatus at the time of the secondary verification. Thus, the anti-passback control is continuously performed.
[0031]
According to a fourth invention (invention according to claim 4), in the second invention, when the control device further determines that the current compartment and the room compartment of the entry source do not coincide with each other from the recording medium. When the identification information that has been read and the unique information of the reader that has read the identification information are sent to the management device and a re-collation request means is provided to request re-collation, the management device further receives a re-collation request from the control device. Corresponding to the identification information sent from the requesting control device, the current section recorded in the current location management information held by itself is read, and the unique information sent from the requesting control device Correspondingly, it reads the room compartment of the entry source recorded in the installation location management information owned by itself, collates the read current compartment with the indoor compartment, and requests the collation result It is provided with a re-verification means for returning to the control device.
[0032]
In this invention, the control device normally performs collation (primary collation) without inquiring of the management device, but the identification information read from the recording medium only when it is determined that there is a mismatch (anti-passback NG) by this collation. The unique information of the reader that has read the identification information is sent to the management apparatus, and the management apparatus is requested to perform re-collation (secondary collation). The result of the secondary verification in the management device is returned to the requesting control device.
[0033]
When a part or all of the current section in the current position information of the control device is lost during maintenance or the like, since it is determined that the primary verification does not match, secondary verification is performed by the management device. If it is determined that they match in the secondary collation of the management apparatus, the control apparatus rewrites the current section of the recording medium recorded in the current position information of the management apparatus to the indoor section of the entry destination permitted to enter. Thus, in the fourth aspect of the invention, even if a part or all of the current section in the current position information of the control device has disappeared, the disappearance is automatically performed by the current section used for the secondary verification in the management device. Thus, the anti-passback control is continuously performed.
[0034]
According to a fifth invention (invention according to claim 5), in the first to fourth inventions, the current recorded in the current position information corresponding to the identification information read from the recording medium when the control device performs collation If it is an initial value indicating that the section is indeterminate, the current section and the entry source regardless of the room compartment of the entry source recorded in the installation position information of the reader that has read the identification information. In other words, it is determined that the indoor compartment is consistent with the indoor compartment.
According to the present invention, when the current section recorded in the current position information of the control device is set to the initial value corresponding to the identification information written on the recording medium, that is, the current section of the recording medium is still fixed. If not, it is determined that the indoor compartment where the recording medium is currently located and the indoor compartment of the entry source match, and entry is permitted.
[0035]
The sixth invention (the invention according to claim 5) uses the first invention as a method, and can also be provided as a control program for realizing processing by this method. It can also be provided as a recording medium such as a flexible disk, a CD-ROM, or a memory card in which the control program is stored.

[0046]
Hereinafter, the characteristic processing operation in this system will be described by taking as an example the case where Mr. M having the IC card 4 enters the room along the route shown by the solid line in FIG. It is assumed that “card number 003” is written in the IC card 4 owned by M.
[0047]
[Entering indoor compartment ▲ 1 ▼ into indoor compartment ▲ ▼]
In the indoor compartment (1), when Mr. M sets the IC card 4 to the reader 1-2, the reader 1-2 reads the card number “003” written in the IC card 4, and this card number “003” is read. The management code number “READ0002” of the reader 1-2 is sent to the control device 7-1.
[0048]
The control device 7-1 receives the card number “003” and the management code number “READ0002” from the reader 1-2 (steps 701 and 702 shown in FIG. 7), and the current position information DB2 ₁ The current section “-” corresponding to the card number “003” is read (step 703). Also, the installation position information DB1 ₁ The room division (1) of the room entry source corresponding to the management code number “READ0002” is read (step 704).
[0049]
Then, the control device 7-1 collates (primary collation) the current section “−” read in step 703 and the room section (1) of the room entry source read in step 704 (step 705). In this case, the current section is “−” indicating an initial value, and does not match the room section (1) of the entry source, but the control device 7-1 is “−” indicating that the current section has an initial value. If there is, it is determined that the current compartment and the indoor compartment of the entry source match regardless of the indoor compartment of the entry source.
[0050]
Therefore, in this case, the control device 7-1 determines that the current section “−” and the room section (1) that is the entry source coincide with each other, and the result of the primary collation in step 705 is OK. . When the result of the primary collation is OK (YES in step 706), the control device 7-1 determines that the current position information DB2 ₁ The current section corresponding to the card number “003” in “-” is set from “−” to the installation position information DB 1 ₁ Is rewritten to the room section {circle around (2)} that is recorded at (step 707).
[0051]
In addition, the control device 7-1 performs other control on the entry message including the card number “003” read from the IC card 4, the management code number “READ0002” of the reader 1-2, and the room compartment (2) of the entry destination. Global transmission is performed to the devices 7-2 and 7-3 and the management device 6 (step 708). Further, the electric lock (not shown) is unlocked (step 709), and the door of the entrance / exit where the reader 1-2 is installed is opened. Thereby, Mr. M who sets the IC card 4 in the reader 1-2 can enter the indoor compartment (2) from the indoor compartment (1).
[0052]
Upon receiving the entry message from the control device 7-1, the control device 7-2 extracts the card number “003”, the management code number “READ0002”, and the room compartment (2) of the entry destination from this entry message. Location information DB2 ₂ The current section corresponding to the card number “003” is rewritten from “−” to the room section {circle around (2)}. Similarly, the management device 6 extracts the card number “003”, the management code number “READ0002”, and the room image {circle around (2)} of the entry destination from the entry message from the control device 7-1, and present location management information MB <b> 2. The current section corresponding to the card number “003” is rewritten from “−” to the room section {circle around (2)}. The control device 7-3 also extracts the card number “003”, the management code number “READ0002”, and the room section (2) of the entry destination from the entry message from the control device 7-1, but the current location information DB2 ₃ Since the card number “003” is not registered, the current section is not rewritten.
[0053]
[Entering from indoor compartment ▲ 2 ▼ to indoor compartment ▲ 3 ▼]
When M sets the IC card 4 in the reader 1-7 in the indoor section {circle around (2)}, the reader 1-7 reads the card number “003” written in the IC card 4, and this card number “003” is read. The management code number “READ0004” of the reader 1-7 is sent to the control device 7-2.
[0054]
The control device 7-2 receives the card number “003” and the management code number “READ0004” from the reader 1-7 (steps 701 and 702), and the current position information DB2 ₂ The current section corresponding to the card number “003” is read (step 703). In this case, the current position information DB2 in the control device 7-2 ₂ The current section corresponding to the card number “003” is rewritten to the room section (2) by the room entry message from the previous control device 7-1.
[0055]
And control device 7-2 is installation position information DB1. ₂ Is read (step 704), and the current section read in step 703 and the room compartment of the entry source read in step 704 are collated (primary collation). (Step 705). In this case, the current section read in step 703 is {circle around (2)}, the room compartment that has been read in step 704 is also {circle around (2)}, and they match.
[0056]
Therefore, in this case, the control device 7-2 determines that the current section of the IC card 4 matches the room section of the entry source, and sets the result of the primary collation in step 705 to be OK. If the result of the primary collation is OK (YES in step 706), the control device 7-2 determines that the current position information DB2 ₂ The current position corresponding to the card number “003” in “2” is set from the installation position information DB1. ₂ Is rewritten to the room compartment (3) of the room entrance stored in (step 707).
[0057]
In addition, the control device 7-2 performs other control on the entry message including the card number “003” read from the IC card 4, the management code number “READ0004” of the reader 1-7, and the room compartment 3 of the entry destination. Global transmission is performed to the devices 7-1 and 7-3 and the management device 6 (step 708). Further, the electric lock (not shown) is unlocked (step 709), and the door of the entrance / exit where the reader 1-7 is installed is opened. Thereby, Mr. M who sets the IC card 4 in the reader 1-7 can enter the indoor compartment (3) from the indoor compartment (2).
[0058]
The control device 7-1 that has received the entry message from the control device 7-2 extracts the card number “003”, the management code number “READ0004”, and the room compartment (3) of the entry destination from this entry message, Location information DB2 ₁ The current section corresponding to the card number “003” in (2) is rewritten from (2) to the room section (3) of the room entry destination. Similarly, the management device 7 also extracts the card number “003”, the management code number “READ0004”, and the room to be entered (3) from the entry message from the control device 7-2, and in the current location management information MB2 The current section corresponding to the card number “003” is rewritten from (2) to the room section (3) of the room entry destination. The control device 7-3 also extracts the card number “003”, the management code number “READ0002”, and the room section (3) of the entry destination from the entry message from the control device 7-1, but the current position information DB2 ₃ Since the card number “003” is not registered, the current section is not rewritten.
[0059]
[Entering indoor compartment ④ through indoor compartment ▲ 2 ▼ without exiting from indoor compartment ▲ ▼]
In the example of FIG. 2, Mr. M opens the door without the reader from the indoor section {circle around (3)}, temporarily exits to the indoor section {circle around (2)}, and sets the IC card 4 in the reader 1-9. In this case, the reader 1-9 reads the card number “003” written in the IC card 4, and sends the card number “003” and the management code number “READ0008” of the reader 1-9 to the control device 7-2. send.
[0060]
The control device 7-2 receives the card number “003” and the management code number “READ0008” from the reader 1-9 (Steps 701 and 702), and the current position information DB2 ₂ The current section corresponding to the card number “003” is read (step 703). In this case, the current position information DB2 in the control device 7-2 ₂ The current section corresponding to the card number “003” is rewritten to the indoor section {circle around (3)} by the card operation at the previous reader 1-7.
[0061]
And control device 7-2 is installation position information DB1. ₂ The room division {circle around (2)} corresponding to the management code number “READ0008” is read (step 704), and the current division read in step 703 and the room division of the entry source read in step 704 are collated (primary collation). (Step 705). In this case, the current section read in step 703 is (3), the room compartment that has been read in step 704 is (2), and they do not match.
[0062]
Therefore, in this case, the control device 7-2 determines that the current section of the IC card 4 does not match the room section of the entry source, and sets the result of the primary collation in step 705 as NG. When the result of the primary verification is NG (NO in step 706), the control device 7-2 sends a reconfirmation request to the management device 6 (step 710), and the current position management possessed by the management device 6 A request is made to return the current section recorded corresponding to the card number “003” in the information MB2.
[0063]
Upon receiving the reconfirmation request from the control device 7-2, the management device 6 reads the current section (3) recorded in the current location management information MB2 corresponding to the card number “003”, and controls the control device 7- Return to 2.
The control device 7-2 receives the current section returned from the management apparatus 6 (step 711), and re-establishes the current section returned from the management apparatus 6 and the room section of the entry source read in step 704. Collation (secondary collation) is performed (step 712). In this case, the current section returned from the management apparatus 6 is (3), the room section of the room entry source read in step 704 is (2), and they do not match.
[0064]
Therefore, in this case, the control device 7-2 determines that the current section returned from the management apparatus 6 does not match the room section of the entry source, and sets the result of the secondary collation in step 712 as NG. To do. If the result of the secondary verification is NG (YES in step 713), the control device 7-2 regards the traffic as unauthorized, sends a warning message to the reader 1-9, and displays an indication that the room cannot be entered on the screen. Do. As a result, entry from the indoor compartment (2) to the indoor compartment (4) is prohibited, and entry / exit restriction is performed by anti-passback control.
[0065]
If the secondary verification result is NG, the control device 7-2 transmits the secondary verification result (anti-passback NG) to the management device 6 (step 715). In this case, the secondary collation result from the control device 7-2 is displayed on the screen of the management device 6, for example, as shown in FIG. During this display, “Status” indicates that anti-passback control has been executed. In addition, the current section of the card recorded in the current position management information MB2 is displayed in “Original section”. In this example, since the current section of the card number “003” is (3), “1F shared section” corresponding to the indoor section (3) is displayed.
[0066]
[Reset method for each card in case of anti-passback NG]
There are two reset methods for each card in the case of anti-passback NG: resetting by operation and resetting by the function of the management device 6.
[0067]
(1) When resetting during operation
In the case of resetting in operation, the person (IC card) who became anti-passback NG is moved to “original section” by the electric lock unlocking operation from the management device 6 or the master card of the security officer, and from there Have a rematch operation.
[0068]
(2) When resetting by the function of the management device
In the display shown in FIG. 8A, the card number is designated and the anti-passback reset operation is performed. Then, an anti-passback reset operation window W1 as shown in FIG. 8B is displayed on the screen of the management apparatus 6.
[0069]
In the “original section” of this window W1, the permitted section recorded in the permitted designation section information MB3 is displayed corresponding to the card number. In this example, indoor compartments {circle around (2)}, {circle around (3)}, {circle around (4)} are displayed as permission compartments of the card number “003”. This permission section can be added or deleted by the administrator in the window W1.
[0070]
When the permitted section displayed in the “original section” is confirmed in the window W1 and the execution button BT1 is pressed, a reset message including information described in the window W1 is transmitted to the control device 7-2.
[0071]
The control device 7-2 receives the reset message from the management device 6, and reads from this reset message that the permitted section of the card number “003” is the indoor section (2), (3), (4), The indoor compartments (2), (3), and (4) are regarded as the current compartment corresponding to the card number “003” and collation is performed again. In this case, the room section from which the reader 1-9 enters is (2), and the current section of the IC card 4 set in the reader 1-9, that is, the permission section of the card number “003” is (2), Since 3 ▼ and {4}, the room compartment of the room entry source matches the current compartment of the card number “003”.
[0072]
Thereby, the anti-passback NG in the control device 7-2 so far becomes the anti-passback OK, the electric lock (not shown) is unlocked, and the door of the doorway where the reader 1-9 is installed is opened. be opened. As a result, Mr. M who has not performed the exit operation in the indoor section (3) can enter the indoor section (3) from the indoor section (2).
[0073]
In this case, the control device 7-2 uses the current position information DB2 ₂ The current section corresponding to the card number “003” is rewritten from (3) to the room section (4) at the entry destination. In addition, the control device 7-2 performs other control on the room entry message including the card number “003” read from the IC card 4, the management code number “READ0008” of the reader 1-9, and the room compartment (4) of the room to be entered. Globally transmitted to the devices 7-1 and 7-3 and the management device 6, and the current position information DB2 of the control device 7-1 ₁ In addition, the current section corresponding to the card number “003” in the current position management information MB2 in the management device 6 is rewritten from (3) to (4). Accordingly, the anti-back control is continuously performed in the same manner as when the management section {circle over (2)} is legally entered into the management section {circle around (4)}.
[0074]
In the above description, the reset method for each card in the case of the anti-bus pack NG has been described. However, the anti-passback control is not performed by designating the card and inputting the initial value “−”. It is also possible to make it. Actually, such an initial value “−” is input. It is also possible to stop anti-passback control for all cards.
[0075]
For example, for the card number “003”, the current position information DB2 in the control device 7-1. ₁ , Current position information DB2 in the control device 7-2 ₂ If the corresponding current section in the current position management information MB2 in the management apparatus 6 is locked to the initial value “−”, the anti-passback control is performed in all the management sections for the IC card 4 with the card number “003”. Can not be.
[0076]
Similarly, for all the card numbers, if the current section corresponding to the card number is locked to the initial value “−”, the anti-passback control can be stopped for all the IC cards 4 in all the management sections. In addition, by setting a permission designation section as the current section and locking it, it is possible to stop the anti-passback control for each management section or stop the anti-passback control for each reader.
[0077]
[When the current section of the current position information has disappeared in the control unit]
In the control device 7-2, for example, during the maintenance, the current position information DB2 ₂ It is assumed that a part (including the card number “003”) or all of the current section in FIG.
In this case, in FIG. 2, when Mr. M sets the IC card 4 in the reader 1-7, the reader 1-7 reads the card number “003” written in the IC card 4, and this card number “003” is read. The management code number “READ0004” of the reader 1-7 is sent to the control device 7-2.
[0078]
The control device 7-2 receives the card number “003” and the management code number “READ0004” from the reader 1-7 (steps 701 and 702), and the current position information DB2 ₂ The current section corresponding to the card number “003” is read (step 703). However, since the current section corresponding to the card number “003” has disappeared, it cannot be read. For this reason, in the primary collation in step 705, it is determined that there is a mismatch.
[0079]
When the result of the primary verification is NG (NO in step 706), the control device 7-2 sends a reconfirmation request to the management device 6 (step 710), and the current position management possessed by the management device 6 A request is made to return the current section recorded corresponding to the card number “003” in the information MB2.
[0080]
Upon receiving the reconfirmation request from the control device 7-2, the management device 6 reads the current section (2) recorded in the current location management information MB2 corresponding to the card number “003”, and controls the control device 7- Return to 2.
The control device 7-2 receives the current section returned from the management apparatus 6 (step 711), and re-establishes the current section returned from the management apparatus 6 and the room section of the entry source read in step 704. Collation (secondary collation) is performed (step 712). In this case, the current section returned from the management device 6 is {circle around (2)}, and the room section of the entry source read in step 704 is {circle around (2)}, and they match.
[0081]
Therefore, in this case, the control device 7-2 determines that the current section of the IC card 4 matches the room section of the entry source, and sets the result of the secondary collation in step 712 to OK. When the result of the secondary collation is OK (YES in step 713), the control device 7-2 determines that the current position information DB2 ₂ The current section corresponding to the card number “003” is rewritten from (2) to the room section (3) at the entry destination (step 707).
[0082]
In addition, the control device 7-2 performs other control on the entry message including the card number “003” read from the IC card 4, the management code number “READ0004” of the reader 1-7, and the room compartment 3 of the entry destination. Global transmission is performed to the devices 7-1 and 7-3 and the management device 6 (step 708). Further, the electric lock (not shown) is unlocked (step 709), and the door of the entrance / exit where the reader 1-7 is installed is opened. Thereby, Mr. M who sets the IC card in the reader 1-7 can enter the indoor compartment (3) from the indoor compartment (2).
[0083]
In this way, the current position information DB2 of the control device 7-2. ₂ Even if a part or all of the current section is lost, the current section returned from the management device 6 automatically compensates for the disappearance, and the anti-passback control is continuously performed. Similarly in the other control devices 7-1 and 7-3, the current position information DB2 of the control devices 7-1 and 7-2. ₁ , DBA2 ₃ Even if a part or all of the current section is lost, the disappearance is automatically compensated by the current section returned from the management device 6, and the anti-passback control is continuously performed.
[0084]
[When there is no response from the management device 6]
For example, even if a reconfirmation request is sent from the control device 7-2 to the management device 6, the management device 6 may be down and the current partition may not be returned from the management device 6. In such a case, all the secondary collation results are OK, all secondary collation results are NG, only those with high importance are secondary collation results OK, etc. Is possible. Which method is used is determined according to the system operation.
[0085]
As can be seen from the above description, according to the present embodiment, the current section of the IC card 4 is shared by all the control devices 7 and management devices 6 that can use the IC card 4. Anti-passback control can be performed even when the IC card 4 is used across the management section S of the control device 7. In the present embodiment, the control device 7 normally performs collation (primary collation) without inquiring of the management device 6. Therefore, the time required for collation including the communication time is short, and collation is performed at high speed.
Further, in the present embodiment, only when the anti-passback NG is determined by the primary verification, the management device 6 is inquired and the secondary verification is performed, so that unnecessary alarms are eliminated and the reliability is improved. . Further, since the management device 6 is inquired only when there is an abnormality, the load does not concentrate on the management device 6.
Further, according to the present embodiment, even if the current section in the current position information DB 2 of the control device 7 disappears during maintenance or the like, the disappearance is caused by the current section returned from the management apparatus 6 during the secondary verification. Since it is automatically compensated, the anti-passback control is continuously performed.
[0086]
In the above-described embodiment, when the current section in the current position information DB2 in the control device 7 disappears, the current section recorded in the current position management information MB2 is sent from the management apparatus 6 to the control apparatus 7, and the control apparatus 7 may be restored.
[0087]
In FIG. 1, the management device 6 is omitted, and for example, the current position information DB 2 in the control device 7-1. ₁ Current location information DB2 in the control device 7-2 ₂ Current position information DB2 in the control device 7-3 ₃ Is sent to the control device 7-1 and the current position information DB2 in the control device 7-1 is sent. ₁ May be restored.
[0088]
When the management device 6 is omitted, the control device 7 shares only the current partition of the IC card 4 that can be used in the management partition S. Therefore, in the control device 7 in which the current partition has disappeared. In some cases, the current position information DB 2 cannot be completely restored. On the other hand, when the management device 6 is provided, the management device 6 shares the current partition with respect to the IC card 4 that can be used in all the management partitions. 7 can be completely restored.
[0089]
Further, in the above-described embodiment, when it is determined that there is a mismatch (anti-passback NG) by the primary collation in step 704, the control device 7 sends back the current section recorded in the current location management information MB2. 6, the control device 7 uses the current section returned from the management device 6 to perform the secondary verification, but the management device 6 performs the secondary verification, and the secondary verification result. May be returned to the control device 7.
[0090]
In this case, if it is determined that there is a mismatch (anti-passback NG) by the primary verification in step 704, the card number and the management code number are sent from the control device 7 to the management device 6 and a re-verification is requested. When receiving a re-collation request from the control device 7, the management device 6 reads the current section recorded in the current position management information MB2 corresponding to the card number sent from the requesting control device 7, Also, in response to the management code number sent from the requesting control device 7, the room compartment of the entry source recorded in the installation position management information MB1 is read, and the read current compartment and the indoor compartment are collated, The collation result is returned to the requesting control device 7.
[0091]
【The invention's effect】
As is apparent from the above description, according to the present invention, the current section of the recording medium is shared by all control devices and management devices that can use the recording medium, and adopts a controller control method. It is possible to perform anti-passback control even for the use of a recording medium across management sections while inheriting the advantages (high-speed verification, load distribution, etc.) of the entry / exit management system.
Even if the current section of the recording medium disappears in the control device, other control devices and management devices that can use the recording medium share the current section of the recording medium. The lost current partition can be recovered by the current partition shared by the control device and the management device, and the anti-passback control can be continuously performed.
