Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention protects a personal identification medium, a reader for reading the same, and personal identification data read by the reader against the personal identification data registered and stored in advance. Manage access to the area,
Regarding the access control system, the personal identification medium includes biometric information represented by fingerprints and voiceprints, magnetic cards,
A personal identification card (ID card) such as an IC card is used. In the following, IDs are usually used to identify personal identification data.
(IDENTITY / DATA).

2. Description of the Related Art Keys have been used most often in the past as access control for a protected area. This method is still used as a common sense in personal houses, etc., but as the number of people entering and exiting a company, a research laboratory, or an important facility office increases, the number of keys increases, and , In the same area, some specific areas are often set, but in this case, each person has multiple keys that are different from each other, including lost or duplicated areas.
It is extremely difficult to manage. Also, in factories,
Although many guards and other personnel check the visitors at the time of entry, it is difficult to grasp the behavior of the visitors after entry, and it cannot be said to be complete in terms of management, security, and safety.
Therefore, personal identification information (ID) was used as a method of entering and leaving the protected area to improve these points.
Access control is performed, and an example of this most basic configuration and flowchart is shown in FIG. Although FIG. 1 shows an example using an ID card that is most frequently used, the same applies when a biometric ID such as a fingerprint or voiceprint is used. In this example, the reader can enter the protected area by reading the ID of the registered ID card. For example, when the ID card is lost, it can be invalidated by deleting the registration of this card. I can. This example can be said to be a system that is particularly safe and secure against loss in a relatively small-scale entry / exit management system as compared with a system using a key. However, as the scale becomes larger, the apparatus shown in FIG. 1 is often inadequate for access control to a plurality of areas of different importance, for example, in a laboratory, factory, office building, or the like. Because the ID used in the system of FIG.
All cards have the same function. In this respect, since the key can be used only for one keyhole as in the case of the conventionally used key, when there are a plurality of areas having different importance levels, it is necessary to limit the persons who can enter and leave each area.
That is, when a plurality of keyholes are required and the device of FIG. 1 is used,
It is necessary to properly use a plurality of ID cards according to the importance of the area to enter and leave. Therefore, FIG. 2 shows an example of an improved configuration and a flow chart for managing a relatively large area. In this system, for each ID card, a level representing a reader usable by this card is added to the ID and stored. On the other hand, the control device has a means for storing an accessible reader, a day of the week, a time, etc. for each level. Naturally, in such a comparatively large-scale entry / exit management system, people of various occupations coexist, and the area and time required for entry / exit are not constant. May be duplicated at different levels. In this way, by introducing the concept of level into the access control system, each ID card will have a function according to its importance or role, increasing the flexibility of the access control system. And depending on the structure of the protected area,
There are fewer restrictions on introducing access control systems. However, the conventional access control system, for example, when it is necessary to define the order of the actions of entering the area A and then the area B, the order is provided unless the areas A and B are directly adjacent to each other. There was a drawback that you couldn't.
These are, for example, a case where a shower is provided and then a clean room is entered, or a change in a locker room is performed before entering an office, and vice versa. Further, the conventional access control system has a drawback that it is difficult to guide a safe route to a visitor to a factory in a safe order. Further, the conventional access control system finds a specific person or a specific room from the history of all past readers when investigating which area a certain person is currently in or who is currently in a certain area. Since there is a need, there is a drawback that the storage means becomes large and the survey takes time. These investigations are necessary, for example, in the case of telephone transfer, evacuation and guidance in the event of an accident, and should be performed within a very short time.

SUMMARY OF THE INVENTION The present invention eliminates the drawbacks of conventional access control systems and makes it possible to provide a more advanced and reliable access control system at a lower cost.

[0004]

According to the present invention, at least an identification medium capable of identifying each individual, a plurality of readers for reading personal identification data of the identification medium, and personal identification data from the reader are stored. In the entry / exit management system that uses a control device that controls the opening and closing of the door by collating with the already stored personal identification data, a symbol indicating the route is added to each reader, and the control device sets the personal identification data of each individual to the end. An access control system having a means for storing the read reader symbol for each personal identification data is obtained.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 is an embodiment of the present invention 1, FIG. 4 is a flowchart for reading and unlocking an ID by a reader shown in FIG. 3, and FIG. 5 is an example of stored data. Although one type of alarm is shown in FIG. 4, different alarms may be set. 1A-1 in FIG.
C is A area, B area, C area, 2A ~ 2D,
In the reader, 2A is a symbol A, 2B is a symbol B, 2C is a symbol C, and 2D is a symbol D, respectively. Further, 3 is a door that goes in and out of each area, and has a lock that can be locked and unlocked by an electric signal. Now, consider a case where a person having an ID card of a level capable of entering and leaving the areas A to C enters the area C from the outside of the area, and further exits the area via the areas B, C, and A. First, the holder of the ID card causes the 2C to read the ID. At this time, the control device is housed inside,
The ID is compared with the ID read by the 2C, and if the ID and the level match, the lock of the door 3 leading to the IC is unlocked.
Cardholders can enter Area C. An example of the format in which the ID of the ID card owner at this time is stored in the control device is shown in Fig. 5 (1).
The symbol C of the reader reading is added. Of course, the format is not limited to this. The reader symbol may be added to the ID when the door 3 is opened. This prevents erroneous recognition when the reader reads the ID but does not enter the area C for some reason. Next, consider a case where the ID card holder moves from the area C to the area B. When the ID card owner causes the reader 2B to read the ID, the lock of the door 3 leading to the area B is unlocked, and the ID card owner can enter the area B as described above. An example of the ID format at this time is shown in FIG. 5 (2), and the reader symbol is the symbol B of the last reader. Similarly, when the ID card owner moves from area B to area C, it is shown in Figure 5 (3), and when it is moved from area C to area A, it is shown in Figure 5 (4) and again area C.
When moving to area 5 in FIG. 5 (5) and outside the area, in FIG. 5 (6), the leader symbol is D, indicating that the area is outside the area. As described above, when the present invention 1 is used, the area where each owner is located is added to each ID. Of course, the area name and the reader symbol are not limited to A to C, and can be arbitrarily determined. There may be a plurality of the same symbol as the leader symbol, or the reading time of the reader may be added. By using the present invention, it is possible to determine the current position of a specific individual, the number of ID card holders located in a timed area, and the ID by simply searching for the ID of the ID card registrant stored in the control device. You can know in a short time,
It is possible to effectively and safely proceed with evacuation due to telephone transfers and accidents. Further, by providing the control device or the management device connected thereto with the function of collating the ID with the name and the employee number, it is possible to search by the name or employee number. In order to know the current position of a specific individual and the number of ID card holders located in a specific area with the access control system used conventionally, the IDs read by all readers are always stored, and when searching, the past It is necessary to find the desired ID from all the reading histories of all the readers, and with an enormous storage capacity,
It requires much longer search time than the present invention. As described above, by using the first aspect of the present invention, it is possible to provide a simple access control device that has a simplified control device, a shorter search time, and better management and safety. According to the second aspect of the present invention, a certain reading order is set for the symbols of the reader, and only the reader according to this order can read the ID. FIG. 6 is an embodiment of the present invention 2, FIG. 7 is the same flowchart, and FIG. 8 (1) is an ID to which each symbol is added.
It is the figure which showed the symbol of the reader which a card can read normally. The leader symbol added to the ID in Figure 6 is the ID
The initial state of the card is set to 0, and the route of 1-2-3-4-5 is set. Further, in FIG. 6, 1-1 to 1-4 are areas 1 to 4, 2-0 to 2-5 are readers of symbols 0 to 5, 3
Has a lock that can be locked and unlocked by electric signals at the doors entering and exiting each area. At the level where you can enter / exit areas 1 to 4,
Considering the case where a person who has a card in the initial state goes in and out of areas 1 to 4, the initial state, that is, the ID card with the symbol 0,
Since the leader symbol that can be normally entered and exited is 1, the ID
Cardholders cannot enter areas 1-4 directly,
In order to enter the areas 1-1 to 1-4, first, the reader 2-1 must read the ID of the ID card. The reader symbol of the ID card in the area 1-1 is 1. The reader symbols that this ID card can pass are 0 and 2.
Thus, the cardholder can either enter the area 1-2 or exit the area via the reader 2-0. Similarly, the cardholder who entered 1-2 can enter either 1-1 or 1-3, and
It is possible to get out of the area by the leader of 2-5 via 1-3 and 1-4. At this time, since the symbol added to the ID of this ID card is 5, the owner of this card can enter the area 1-4 but cannot directly enter the area 1-1. If 1-1 is a shower room and 1-2 to 1-4 are clean rooms, the ID card holder cannot enter the clean room without going through the shower room. FIG. 6 shows an example in which each area is directly connected, but the same applies when each area is independent. An example of this is shown in FIG. In this example, a person who has passed through the entire entrance 4 and entered the area cannot enter 1-2 or 1-3 without going through 1-1. In the above example, the ID card holder can freely move in and out of each area once he / she enters the area, but as shown in Fig. 8 (2), he / she can only pass through a predetermined route in one direction. Is also good. In this case, the door that has passed once cannot be passed through in the opposite direction, which is effective for an ID card or the like to be distributed to visitors. Further, according to the present invention, when a door opened by someone else is passed without performing a reader operation, the symbol of the reader is not added to the ID so that the person cannot leave the area alone. It is also effective in preventing unauthorized use of the system due to getting used to it, which tends to occur when managing the access control system. Invention 3 provides a difference between any one of the symbols representing the route of the reader and another arbitrary symbol,
It is recognized as 1. Taking Fig. 6 as an example, by recognizing the difference in the route between symbol 5 and symbol 1 as 1,
A person who goes out of the area from 4 can enter any of 1-4 and 1-1. FIG. 10 shows the symbols of the reader that can normally read the ID card to which each symbol is added in this example. Invention 4 is to reset the reader symbol of each ID card to an initial state at a certain time. Figure-
Taking 6 as an example, there are cases where only a system having a configuration that allows the user to directly go home from 1-4 in a factory or the like.
Further, in FIG. 9, the symbol of the ID card is reset when passing through the door 4 that goes inside and outside the area, but the door 4 may not be provided in some cases. Invention 4 is to reset the ID card reader symbol to the initial state in the control device at 2:00 am when all employees return home at a certain time, for example, in a factory, so that only the prescribed route can be used when coming to work on a day of the week. It does not allow passage. Of course, for example, in the case of a factory with three shifts, multiple times for resetting the symbols may be set for each work.
It may be set for each card. It is also possible to provide a special reader in a guard station or the like, which is not restricted to the normal route, and have the reader read the ID when returning home to reset the reader symbol of the ID to the initial value.
