Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a room entry/exit control system, and in particular, to a plurality of control areas (hereinafter referred to as
It relates to something that is suitable for application to a management target in which a room (referred to as a room) exists.

[Technical protection of the invention and its problems] As shown in FIG. 8, the rooms 1mA and 1mB have different security levels as objects to be managed where entry and exit are controlled.

In some cases, C1 exhibits a hierarchical structure.

°For example, in computer centers, information leakage,
In order to ensure security in case the system to be controlled goes down, only some people are allowed to enter the room, and some of them are allowed to enter Building A, but they are not allowed to enter Building A. Computer room B with high security level
Persons who are not allowed to enter Computer Room B, Persons who are allowed to enter Computer Room B but not allowed to enter File Storage Room C, which has a higher security level, and Persons who are not allowed to enter File Storage Room C. Qualifications were divided into those who were permitted to do so.

Conventionally, this type of room entry/exit control has been performed using gates GA that connect rooms with different security levels when they are opened.
, GB, and GO were individually controlled to open and close. Therefore, the management method is as follows: First, when a password such as a PIN number known only to those who are allowed to pass is entered from a key bat installed on the outer wall near the gate, passage through the gate is permitted. Method, 2nd
An identification card (ID card) with a password stored on it
A method was adopted in which a magnetic card (as a card) was inserted into a card checker to determine who was allowed to pass and allow them to pass through the gate.

However, according to the first method, the password is
However, it is still insufficient to control entry and exit for rooms with a high security level. Further, according to the second method, once the magnetic card falls into the hands of a third party, it is complicated to collect all the cards and re-enter the password.

In addition, according to the second method, those who are qualified to enter rooms with a high security level must carry as many magnetic cards as there are gates, and must replace and insert magnetic cards at each gate. First, it had the disadvantage of low operability.

[Purpose of the Invention] The present invention has been made based on the above-mentioned circumstances, and is capable of providing sufficient safety to a managed object that has multiple rooms with different levels of entry permission conditions through simple operations by a person wishing to enter or exit the room. The purpose is to provide a room entry/exit control system that can control entry and exit.

[Summary of the Invention] In order to achieve the above object, the present invention has a system in which a qualification level corresponding to a security level room that the holder can enter is written in advance on an ID card, and a card checker detects when the ID card is inserted. Entry/exit is controlled on the condition that the qualification levels match, and it is possible to enter/exit a plurality of rooms with one ID card, improving operability and safety.

[Embodiment of the Invention] The present invention will be described below with reference to an illustrated embodiment. The objects to be managed in this embodiment have the hierarchical structure shown in FIG. 8 mentioned above.

In FIG. 3, reference numeral 1 indicates the operation panel of the card checker provided corresponding to each gate GA, GB, and GO. A keypad 4 consisting of an end key 4b, an input operation correction key 40, and a card insertion slot 3 into which an ID card 10 is inserted are provided. An insertion port 6 is provided.

The ID card 10 is, for example, an IC card, and as shown in FIG.
It is provided with an E'PROME configuration and a connector 13 that is electrically connected to the card checker control section 20 shown in FIG. 5 when the ID card 10 is inserted into the card insertion slot 3 or 6.

The memory 12 stores a personal identification number related to the bearer, the qualification level of the bearer, that is, the limit of the security level of a room that the bearer can enter, and a position flag indicating the bearer's current location.

The MPU 11 transfers the password, qualification level, and position flag to the checker control unit based on instructions from the checker control unit 20, and also performs operations such as replacing the position flag.

Checker control unit 20 is a card checker and ID card 1
Microcomputer (MPU) in charge of overall control of 0
21 and an EP that stores the processing program for room entry/exit management.
A memory 22 having a ROM configuration is provided.

The checker control unit 20 also has a keypad interface circuit 23, and receives key manual signals from the keybat 4,
For example, a personal identification number is taken in through the interface circuit 23.

Furthermore, the checker control unit 20 corresponds to the card insertion slot 3 for entering the room and the card insertion slot 6 for leaving the room, which are connected to the connector 13 of the ID card 10 when the ID card 10 is inserted into the card insertion slot 3 or 6. A card ink interface circuit 26 for entering the room and a card interface circuit 27 for leaving the room are provided to provide an interface between the provided connectors 24 and 25 and the card. 25
Data is exchanged with the ID card 1o via the interface circuit 27 and the ID card 1o. Furthermore, the checker control unit 20 includes a control interface circuit 28, and is configured to send opening/closing control signals to gates provided between rooms with different security levels via the interface circuit 28. There is.

Here, to explain the qualification level based on FIG. 6, a person whose qualification level stored in the memory 12 of the ID card 10 is rAJ can only use the gate GA shown in FIG. 8 using the ID card 10. Those who pass through and are allowed to enter room A, and whose qualification level is rBJ, enter gate GA.
After passing through GB and GB, you will be allowed to enter room B.
Persons with qualification level rCJ can pass through all gates GA-Qc and are permitted to enter up to room C.

As shown in Fig. 7, the position flag consists of 3-bit flags a, b, and c, and when the a, b, and c flags are all set to logic "1", it indicates that the ID card 10 is possessed by someone outside the management target. When the a flag is logic rOJ and the b and C flags are rising to logic "1", the part @A
The a and b flags are logical r.
In OJ, when only the C flag is rising to logic "1", it indicates that the owner is in room B, and when all flags are falling to logic "0", it means that the owner is in room C. It shows.

Therefore, as shown in FIG. 6, those with qualification level rAJ only need to check and update the C flag, and those with qualification level rBJ only need to check and update flags a and b. For those who do, all they have to do is check and update all flags.

The entry/exit management system having the configuration shown in FIGS. 3 to 5 and using various control signals having the contents shown in FIGS. 6 and 7 operates according to the processing procedure shown in FIG. 1 when entering the room.

That is, the operation is started in step S1, and in the next step S2, the holder passes the ID card 10 to the first gate GA.
Insert the card into the entry card slot 3. At this time,
In the checker control unit 20, the MPU 21 controls the card 10.
It is detected through the connector 24 and the interface circuit 26 that the memory 22 is attached, and the program of the memory 22 is started.

Then, the MPU 21 captures the PIN number that the holder entered into the keypad 4 in step S3, and also inputs the ID number.
The password stored in the memory 12 is transferred from the card 10, and the password is verified in the next step S4.

If a negative result is obtained in step S4, passage is refused and the process proceeds to step S5, where the ID card 10 is ejected into the card insertion slot 3. On the other hand, if a positive result is obtained in step S4, the MPU 21 sequentially proceeds to the next steps S6 and S7, sequentially transfers and imports the qualification level and position flag from the ID card 10, and then proceeds to step S8. A decision is made on whether to allow passage.

For example, ID card 10 of a holder whose qualification level is rAJ.
If so, the passage condition is satisfied for this gate GA. Further, since the holder who inserts the I'D card 10 into the card insertion slot 3 of this gate GA is outside the management target, the passage condition is satisfied when the position flags a, b, and c are rllllJ.

If a negative result is obtained in step S8 by not satisfying at least one of these passage conditions, the process moves to step S5, where the MPU 21 refuses passage and causes the ID card 10 to be ejected into the card insertion slot 3.

On the other hand, if a positive result is obtained in step S8 by satisfying the passing conditions regarding the qualification level and the position flag, the process proceeds to step S9, where the MPU 21 transfers an update command to the MPU 11 of the card 10 and flags the position flag a.
, b, c indicating room A when passing from MIIJ
After updating to ollJ, in step S10 ID card 1
0 is discharged into the card insertion slot 3. Immediately thereafter, in step S11, the MPU 21 gives an opening operation command to the gate GA via the gate door interface circuit 28. As a result, the gate GA is unlocked and automatically opens.

The holder enters the room 11A in step S12 by opening this gate GA, and if the owner wishes to enter a room with a higher security level than this part UA, the owner enters the room in the next step S1.
By obtaining an affirmative result in step 3, the entry operation from step S2 described above is repeated for the new gate G8. On the other hand, if this is not desired, a negative result is obtained in step 813, and the process proceeds to step S14, where the series of room entry operations ends.

In this way, there are conditions such as possessing the ID card 10, knowing the password, satisfying the qualification 1 novel, and a location flag that is updated according to the location. By satisfying the four conditions of corresponding to the location, the holder can pass through each gate and enter the desired room.

Therefore, those who do not have the ID card 10, those whose qualification level is lower than the room they wish to enter, those who enter a room whose location flags do not match due to damage to the wall, and those who do not have a password. Anyone who does not know this information cannot enter the room.

On the other hand, in the total entry/exit management system of the above-described embodiment, when leaving the room, operations are performed according to the processing procedure not shown in FIG. 2. That is, the process starts in step 820, and in the next step S21, the holder inserts the ID card 10 into the card insertion slot 6 for leaving the room. At this time, by connecting the connector 13 of the ID card 10 to the connector 25, the MPU
21 takes out the program for leaving the room from the memory 22, and moves to the next step 822 to read the position flag from the memory 12 of the ID card 10. After that, step S2
It is determined whether the position flag read in step 3 corresponds to the room in which the user is currently located.

If a negative result is obtained in this step 823, the process proceeds to step 824 and, for example, a management center is notified. For example, if someone who enters a room by breaking a wall or window without passing through the gate attempts to leave the room through the gate, the flag on the ID card 10 will correspond to the holder's location. If there is no such person, a report will be made.

If a positive result is obtained in step 823, the process proceeds to the next step S25, and the MPU 21 sends a position flag update command to the ID card 10 to update the position flag to the content corresponding to the room entered by leaving the room. Thereafter, in step S26, the ID card 10 is inserted into the card insertion slot 6.
In step S27, a gate opening control signal is sent to open the gate.

As a result, when the person who wishes to leave the room leaves the room in the next step 828 and also wishes to leave the next room,
If a positive result is obtained in step 829, the above-mentioned step S2
Go back to step 1 and repeat the sequence of leaving the room. On the contrary,
If the user wants to stay in the room he entered, a negative result is obtained in step S29, and the exit operation is ended in step S30.

In this way, when leaving the room, the user is allowed to leave the room by satisfying the conditions that the user is in possession of the ID card 10 and that the location flag corresponds to the room in which the owner is present.

As described above, according to this embodiment, one ID card 1
0 allows the user to enter and leave multiple rooms with different security levels, further improving the operability of the holder, and significantly reducing the possibility of being unable to enter due to forgetting something. In addition, there are multiple conditions for permission to enter and leave the room, so safety will not be compromised.

Incidentally, when controlling entry and exit using one ID card 10, as mentioned above, it is necessary to write the PIN number, location flag, qualification level, etc. on the ID card 10 in advance, which requires a certain amount of storage capacity. Therefore, it is practically difficult to apply a magnetic card to the ID card 10.

Also, since the position flag is updated every time the gate passes,
Laser cards, which require a configuration for rewriting and are difficult to rewrite, are less applicable than IC cards.

Therefore, when attempting to manage entry and exit from a room using one ID card 10, it is desirable that the ID card 10 be constructed of an ID card as described above, and thereby the above-mentioned effects can be obtained.

Although the above example uses the same PIN number for each gate, the PIN number may be changed for each gate, and if the ID card 10 is composed of an IC card, the PIN number may be changed for each gate. Even if the required storage capacity increases in this way, such a configuration can be easily realized. In this way, the conditions for entering a room with a high security level become stricter overall due to the increased number of passwords, and safety can be further ensured.

Further, in the above description, an EEPROM is used as the memory 12, but an EPROM can also be used, and the same effect as described above can be obtained. Note that it is more appropriate to use a separate memory for the position flag that is repeatedly replaced.

Furthermore, in the above description, the position flag indicating the position of the holder is indicated by the same number of bits as the number of security levels, but it may also be used after being coded. can be reduced.

Furthermore, one ID card can be used not only in the same building.
It may be applied to entering and exiting a separate building, and the ID
In the case of using a card, since the storage capacity is large, such a case can be easily handled.

[Effects of the Invention] As described above, according to the present invention, the qualification level corresponding to the room the holder enters is predicted on the ID card, and according to this qualification level, the same ID card can be used to Since entry/exit control is performed for rooms with different security levels, the holder only needs to carry one ID card, and there is no need to search for the desired card, improving operability. The chances of troubles such as losing or misplacing cards can be significantly reduced compared to when carrying multiple cards. As I grow older,
Since the condition for entering and leaving the room is that the qualification level matches, security can be improved compared to a case where entry and exit is permitted simply by possession of an ID card.
