The second lock means 25 for determining whether or not a person passing through 6 and 17 can pass, and the electric locks 21, 22 and 23 of the doors 18, 19 and 20 based on information such as each of the lock means. A control mechanism 26 for controlling the operation.

The first discriminating means 24 is provided with a biometric information acquisition mechanism 27 provided in connection with the entrance 12 to acquire biometric information which is a physical characteristic of a person trying to pass through the entrance 12. And a password display mechanism 28. The second determination means 25 includes input operation mechanisms 29 and 30 provided in association with the entrances 16 and 17.

FIG. 2 shows a block diagram of the traffic control device 10. In the example illustrated in FIG. 2, the biometric information handled by the first determination unit 24 is an iris that handles an iris or pupil image. Therefore, the biometrics information acquisition mechanism 27 includes an iris data reading unit 27a having a camera for photographing an iris, and a data extracting unit 27b for extracting characteristic data from an iris image obtained by the iris data reading unit. Is provided. The password display mechanism 28 of the first determination means 24 includes a display section 28a for displaying the password sent from the control mechanism 26, and an input operation section 28b composed of a numeric keyboard. Further, in the example shown in FIG. 2, each of the input operation mechanisms 29 and 30 of the second determination means 25 comprises a numeric keypad.

As shown in FIG. 2, the control mechanism 26
It comprises a U26a, a ROM 26b, a RAM 26c and an interface 26d, which are interconnected via a bus 26e. Further, the control mechanism 26 uses the bus 26e to control the data extraction unit 27b of the biometric information acquisition mechanism 27, the display unit 28a of the password display mechanism 28, and the numeric keypad 28 of the first determination unit 24.
b, and to the ten keyboards 29 and 30 which are input operation mechanisms of the second determination means 25. Further, the control mechanism 26 has its interface 2
At 6d, it is connected to each of the electric locks 21, 22 and 23.

The CPU 26a operates in accordance with a program stored in the ROM 26b to execute the first discriminating means 24 and the second discriminating means.
And a functional operation unit for controlling the operation of each of the electric locks 21, 22 and 23 in accordance with the result of determination by each of the determination units 24 and 25. I do. Also, in the ROM 26b,
For example, an identification code, such as an ID number, previously assigned to a person who is permitted to pass through the building 11 and iris data of an individual corresponding to the identification code are stored.

A person who intends to enter the building 11 through the entrance 12 closed by the door 20 locked by the electric lock 21 is given to himself / herself using the ten keyboard 28b provided in the entrance 12. Enter the ID number.
The control mechanism 26, in accordance with the program, inputs the I-input to the ten keyboard 28b of the first determination means 24.
The D number is an ID number registered in advance, that is, the ROM 26
It is determined whether or not it matches the ID number stored in b.
When it is confirmed that the ID number input to the numeric keypad 28b matches one of the registered ID numbers, the iris data reading unit 27a uses the camera to read the eye of the person trying to enter the building 11. To obtain an iris image of the subject.

The feature data is extracted from the iris image obtained by the iris data reading section 27a by the data extracting section 27b, and the data is sent to the control mechanism 26. When the control mechanism 26 receives the iris data from the data extraction unit 27b, the control mechanism 26 reads the iris data corresponding to the ID number input to the ten keyboard 28b.
The iris data from the data extraction unit 27b is collated with the registered iris data read from 6b. As a result of the comparison based on the comparison of the two data, if the two match, the person is determined to be a registered person. As a result, for example, a temporary password required for entering each of the rooms 14 and 15 is displayed on the display unit 28a, and the password, the corresponding ID number, and the additional information related to the password for the person correspond to each other. And stored in the RAM 26c. When the password is read and the confirmation key of the numeric keyboard 28b is pressed, the electric lock 21 is unlocked for a predetermined time by the operation of the control mechanism 26, and entry into the building 11 through the entrance 12 is permitted.

ID input to the numeric keyboard 28b
If the number does not match the registered ID number, it is determined that the person is not allowed to enter the building 11, and the electric lock 21 is locked, so that the safety inside the building 11 is maintained. Dripping.

When a person who is allowed to enter the building 11 enters, for example, the room 14 closed by the door 18 from the passage 13, the person operates the numeric keyboard 29 provided at the entrance 16. , Enter your own ID number. The control mechanism 26 determines whether or not the ID number input from the numeric keypad 29 is the one of the person who has previously permitted the passage through the entrance 12 with the ID number corresponding to the password stored in the RAM 26c. Judge by collation. If it is determined that the ID number is that of the person who has permitted the passage through the entrance 12, then the ID number is
It is checked whether or not entry / exit is permitted with the additional information in the RAM 26c. If it is determined that the person is not permitted to enter the room 14, the door 1 of the entrance 16
8 is locked by the electric lock 21,
Entering the room 14 is prevented.

On the other hand, when the user corresponds to a person who is permitted to enter the room 14, the control mechanism 26 requests the input of a password from the numeric keyboard 29. When a person who wants to enter the room 14 operates the numeric keypad 29 to input the password in response to the request for input of the password, the password input by operating the numeric keypad 29 is changed to the above-described entrance. When the password matches the password displayed when passing through the password 12, that is, the password stored in the RAM 26c, the control mechanism 26 operates the electric lock 22 in the unlocked state, assuming that the user can be confirmed. Thus, entry into the room 14 is permitted.

When exiting from the rooms 14 and 15 or exiting from the building 11, the biometrics information acquisition mechanism 27 and the password display mechanism 28 of the first determination means 24 and the second determination means 25 are similar to those described above. By disposing the ten keyboards 29 and 30 on the indoor side of the building 11 and the rooms 14 and 15, respectively, it is possible to manage the opposite movement of the person described above.

As described above, the first discriminating means 24 accurately and accurately determines whether or not a person who intends to enter the building 11 is a person who has been previously permitted to enter the building 11 based on the biometric information. judge. Therefore, it is possible to reliably exclude a suspicious person or the like who is not registered from entering the building 11, and to maintain the security level in the building 11 at a high level. In addition, the second determination unit 25 simply uses a password given when passing through the gate provided with the first determination unit 24 and an ID number given to each person in advance. The movement of the person in the building 11 can be managed. Since this password is given by the first determining means 24 which can determine an individual with relatively high accuracy, unless compared with a card which can be borrowed or illegally obtained, unless the password is actively leaked to another person. , It is possible to maintain higher security.

Accordingly, the movement of a person in the building 11 can be managed cheaply and simply as compared with the first discriminating means 24 without carrying an ID card as in the prior art. Thus, the cost of the entire apparatus can be reduced without requiring a simple card and without lowering the security level in the building 11.

In the above-described example, the input of the ID number from the ten keyboard 28b is required in the first determination means 24, but the ten keyboard 28b can be dispensed with. When the ten keyboard 28b is unnecessary, the feature data of the iris image acquired by the biometric information acquisition mechanism 27 is collated with the registered data in the ROM 26b without referring to the ID number. Therefore, the above-described specific example of selecting the corresponding registration data from a large number of iris data registered with reference to the ID number and comparing the registration data associated with the ID number with the obtained data is required for the matching. This is advantageous in reducing the required time.

In the above-described example, whether the person who is allowed to enter the building 11 is allowed to enter or leave which room 14 or 15 is determined by the ten keyboard 29 of the second determination means 25. Or, when the password and the ID number are input by the operation of 30, the control mechanism 26
Judgment is made from the additional information stored in M26c. Instead of this example, when entering the building 11, at the entrance 12, the ten keyboard 28b of the first determination means 24 can be used to input information on which room 14 or 15 the user is going to enter. . The room 14 and 15 information from the numeric keypad 28b is collated with the data stored in the ROM 26b, similarly to the iris described above. Therefore, unless the input information on the rooms 14 and 15 is that of a room to which a person who intends to enter the building 11 is previously allowed to enter, the person who is allowed to enter the building 11 is not. Even the door 20
The electric lock 21 of the building 1 is locked.
Even entry into 1 can be prevented.

On the other hand, when the input information to the ten keyboard 28b for the rooms 14 and 15 is that of a room to which a person who intends to enter the building 11 is allowed to enter the room in advance, Display unit 28
After the password is given in a, access to the passage 13 is permitted by opening the electric lock 21. When entering one of the rooms 14 and 15 from this passage 13, the operation of the ten keyboard 29 or 30 in the corresponding room
The password and ID number are entered.
As long as the keyboard 29 or 30 does not belong to the room 14 or 15 to which access is allowed, the control mechanism 26 can prevent the ten-key keyboard 29 or 30 from accepting the password input operation itself. Thereby, the security of each room 14 and 15 in the building 11 can be further improved.

In the above, the present invention has been described along an example in which an iris for identifying an individual based on an image of a person's iris or pupil is used as the first determining means of the present invention. Instead of the iris, it is possible to employ a discriminating means based on biometric information, which is a human feature such as a fingerprint, a voiceprint, or a retina.

[0030]

According to the present invention, as described above, the first
The second determining means determines whether or not the person is permitted to pass by the determining means based on the input information of the password and the identification information given by the first determining means. As described above, it is possible to determine whether or not traffic is possible in two stages and at relatively low cost without carrying a card.
