Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an entry/exit control device for controlling entry/exit of a room that requires confidentiality, such as a computer room.

[Conventional technology]

Conventional access/exit control devices place personal identification devices in one-to-one correspondence at the entrances of rooms that require confidentiality, such as computer rooms, and connect these personal identification devices to door opening/closing devices at entrances and exits. In conjunction, the door opening/closing device is opened to allow entry only to persons whose identification information has been registered in advance in the personal identification device. Here, the identification method of the personal identification device uses magnetic data recorded on an ID card, fingerprints, retina, and other identification data unique to the human body.

[Problem to be solved by the invention]

However, in the conventional access control device mentioned above,
When using retinal patterns as personal identification information,
Since the amount of retinal pattern data is as large as approximately 3KB, there is an unresolved problem in private security homes that allow large numbers of people to enter the room, as the storage capacity of the personal identification device becomes enormous.

Furthermore, if room exit management is performed using only a PIN number without using a personal identification device, permission to leave the room will be obtained even if the PIN number of a person in the room is entered incorrectly, but if the person in the room has the correct PIN number, When leaving the room, it will be determined that the input was incorrect and the user will not be able to leave the room. Therefore, it is necessary to use the same personal identification device as when entering the room when leaving the room, resulting in an unresolved problem of increased costs.

Therefore, this invention was made by focusing on the unresolved problems of the above-mentioned conventional example, and uses an IC card to simplify the process by using a personal identification device only when entering the room, and only using the IC card for identification when leaving the room. The purpose of the present invention is to provide a room entry/exit management device that can perform room exit processing in a convenient manner.

[Means for Solving the Problems] In order to achieve the above object, the room entry/exit control device according to the present invention uses an IC card storing personal identification information and an entrance/exit of a security room that requires entry/exit control. located nearby,
A card reader that reads the personal identification information stored in the IC card, a personal identification information reading section that reads the personal identification information of the person entering the room, and a personal identification information read by the card reader and the personal identification information read by the personal identification information reading section. The present invention is characterized in that it includes a personal identification device having a comparison and verification section for comparison and verification. Here, the personal identification information is preferably < turn information of a part unique to the human body such as a fingerprint or an m-membrane pattern. In particular, by combining the pattern information and a password, exit management can be easily performed. It becomes possible to do so.

[Effect]

In this invention, an IC card storing personal identification information such as a retinal pattern or a fingerprint pattern is inserted into a card reader of a personal identification device installed near the entrance of a security room, and the personal identification information is read. The personal identification information of the person entering the room is read by the identification information reading section, the two pieces of personal identification information are compared and verified by the comparison and verification section, and when the degree of coincidence between the two is equal to or higher than a predetermined threshold, the entrance is opened and permission to enter the room is granted.

At this time, the person was permitted to enter a specific security room by storing a PIN number on an IC card along with pattern information such as retina and fingerprints and reading it, or by inputting the PIN number separately using a numeric keypad, etc. It is possible to judge whether or not a person is entering the room, and by storing the password in the IC card, reliable exit management can be performed simply by providing a card reader to read the password when leaving the room.

Next, the operation of the above embodiment will be explained with reference to FIG. 2 showing the processing procedure of the personal identification device.

First, when permission is granted to enter the security room, predetermined registration data is created on the interactive display 15 in the central management device 10, stored in the storage device 13, and the personal identification information input device (not shown) is used to store the retinal pattern and password of the person permitted to enter the room on an IC card, and the person permitted to enter the room is allowed to carry this IC card.

In this way, the person who is permitted to enter the room, who has completed the registration, goes to the security room to which he has been granted permission to enter, carrying his/her IC card. By inserting the IC card into the card reader 1a, the microprocessor unit le of the room entry management identification section l executes the room entry process shown in FIG.

That is, in step (2) it is determined whether or not an IC card has been inserted into the card reader 1a, and if no IC card is inserted, the process waits until the IC card is inserted, and when the IC card is inserted, the process moves to step (2). Then, the retinal pattern information and password stored in the IC card are read, and then the process moves to step (2).

In this step (2), it is determined whether or not a PIN has been input from the PIN input device 1c. If the PIN has not been input, the system waits until the PIN is input. If the PIN is input, step (2) to move to.

In this step (2), it is determined whether the PIN entered from the PIN input device 1c matches the PIN read from the IC card, and if the two do not match, the process moves to step (2) and the error counter is detected. is incremented by "1", and then moves to step (2) to determine whether the count value n of the erroneous input counter is a predetermined value, for example, "3"; if n<3, return to step (2); n=3
If so, proceed to step ■ and insert card reader 1.
Central control device 1 outputs a command to confiscate the IC card to a, and sends an alarm signal with an identification code added to it.
0 and return to step ■.

On the other hand, if the determination result in step (2) is that the password input from the password input device IC matches the password read from the IC card, the process moves to step (2).

In this step (2), it is determined whether or not retinal pattern information has been input from the personal identification information sensor 1b. If this has not been input, the system waits until the retinal pattern information is input, and when the retinal pattern information is input, the process proceeds to step (2). Transition.

In this step (2), the retinal pattern information input from the personal identification information sensor 1b is compared and verified with the retinal pattern information read from the IC card, and the verification information representing the degree of agreement between the two is centrally managed together with the PIN number and identification code. equipment l
O, and then moves to step [phase] to determine whether or not a notification of non-permission to enter the room has been received from the central control device 10 within a predetermined time. If the notification of non-permission to enter the room is not received within a predetermined time, Returning to step (2), when an identification data invalidation notification is received within a predetermined time, the process proceeds to step (2) and the retinal pattern information input from the personal identification information sensor 1b is stored in a predetermined storage area of the storage unit 1r as non-registered data. do.

When the data including the verification information, PIN number, and identification code is received by the central management device 10, the central processing device 1) determines whether the verification information is equal to or greater than a predetermined threshold stored in the storage device 13. If the value is less than a predetermined threshold, a notification of non-permission to enter the room is sent to the entry management identification unit 1 of the personal identification device A, and if the value is greater than or equal to a predetermined threshold, the password is Storage device 1 based on number
3, read out the entry conditions for the person in question, determine whether the entry conditions are satisfied, and if the entry conditions are satisfied, the person is judged to be a person who has been permitted to enter the room, and the corresponding personal identification is determined. A door opening command is sent to the door opening/closing control unit 3 of the device Ai, and the name data of the person entering the room is read out by accessing the storage device 13 based on the PIN number, and the name data, PIN number, current time of entry, and verification are performed. Information etc. are stored in the entry file 12.

When the door opening/closing control unit 3 receives the door opening command, it outputs a control signal of, for example, logical value ``1'' to the drive mechanism 3b to open the automatic door 3a, and then opens the automatic door 3a. After a predetermined time period sufficient for the person to enter the room, the automatic door is closed and the entry process is completed.

Next, when the person who enters the room leaves the room, personal identification device A,
The user inserts the IC card into the card reader 2a of the exit management identification unit 2, and then inputs the password from the password input device 2b. Then, the microprocessor unit 2d determines whether or not the two password numbers match, and if they match, the password and identification code are sent to the central control device IO. Having received this password and identification code, the centralized control system 210 accesses the storage device 13 based on the password, reads out the name data, stores this and the current exit time in the entry file 12, and also stores the name data in the entry file 12. An opening command is sent to the door opening/closing control section 3 of the corresponding personal identification device A cage.

As a result, the door opening/closing control section 3 keeps the automatic door 3a open for a predetermined period of time to allow the person leaving the room.

As described above, according to the above embodiment, the retinal pattern information and the PIN number required for room entry/exit management are stored in the IC card, and the retinal pattern information and PIN number stored in the IC card are stored in the security room. Card reader la of the entry management identification unit l of the personal identification device A installed at the entrance
By comparing these and the input password and retinal pattern of the person entering the room, permission to enter the room is determined.When leaving the room, the IC card's password is read with the card reader 2a, and this and the entered password are checked. With a simple room exit process that only requires matching the password, entry and exit management can be performed reliably without the need for a storage device with a huge storage capacity for personal identification information.

In addition, since each personal identification device compares and verifies the input identification information with the personal identification information stored in the IC card, the central management device IO does not need to compare and verify the personal identification information. Therefore, processing capacity can be reduced, and the occupancy rate of the in-building network can also be reduced. Incidentally, when using a retinal pattern as identification information, the amount of data for identification information is approximately 3 KB, and real-time comparison and verification is performed by the central management device 10.
If this is done locally, the line occupancy rate will increase, and the comparison and verification processing of the central processing unit 10 will be enormous, making it difficult to perform rapid identification processing.

In the above embodiment, a case has been described in which retinal pattern information is applied as personal identification information, but the present invention is not limited to this, and identification information unique to the human body such as fingerprints and handprints can be applied.

Furthermore, in the above embodiment, a case has been described in which personal identification information and a PIN number are stored in the IC card, but the PIN number is omitted and when the PIN number is input, it is registered in the central management device IO. The presence or absence of a password may be searched.

Furthermore, in the above embodiment, a case has been described in which the central management device 10 is applied and used to perform room entry/exit control, but the management function of the central management device IO is added to each personal identification device fAt. It's okay.

Furthermore, in the above embodiment, the personal identification device A1
Although the case where the AM and the central management device 10 are connected via the in-building network 6 has been described, the present invention is not limited to this, and the connection may be made using a dedicated line.

〔Effect of the invention〕

As explained above, according to the present invention, the personal identification information stored in the IC card is read by the card reader of the personal identification device installed near the entrance of the security room, and the personal identification information and the personal identification information are read. The comparison unit compares the personal identification information input from the reading unit to determine whether the person is an authorized person to enter the room, so the personal identification information for comparison and verification is sent to the personal identification device. There is no need to provide a storage section for storing data, and it is possible to achieve the effect that reliable room entry management can be performed with a small storage capacity.

Also, the retina, which is unique to the human body, serves as personal identification information.

By applying pattern information such as fingerprints, 2 handprints, etc., highly accurate room entry management can be performed.

Furthermore, by storing personal identification information and a PIN number on an IC card, it can be used as a personal identification device for leaving the room without using an expensive personal identification device that compares and verifies personal identification information. Accurate room exit management can be performed without erroneous judgments through simple room exit processing.
