[Technology to which the invention belongs]
The present invention relates to an entrance / exit management device.
[0002]
[Prior art]
As a device for managing persons entering and leaving the important area, a device described in Patent Document 1 is conventionally known. In this conventional example, authentication means such as a card reader or fingerprint authentication means are arranged at both the entrance and exit to the important area, and the entrance / exit history to the important area is managed by passing these authentication means when entering and leaving the room. The

[Problems to be solved by the invention]
However, in the conventional example described above, in the entrance / exit management device using a card reader or the like as an authentication means, it is impossible to completely prevent impersonation or the like due to unauthorized use of the card, and the security is low. Have
[0005]
On the other hand, it is known that when a biometric authentication device such as a fingerprint recognition device is used as an authentication means, security is significantly improved. However, a biometric authentication device is generally expensive and is used for both entrance and exit authentication. The device has the disadvantage that it becomes very expensive.
[0006]
The present invention has been made to solve the above-described drawbacks, and an object thereof is to provide an entrance / exit management device that is inexpensive and highly safe.
[0007]
[Means for Solving the Problems]
When managing entry / exit to important areas, it is necessary to restrict entry / exit in a state that does not remain in the entry / exit history. It is necessary to arrange a lock operating member.
[0008]
On the other hand, when considering entry / exit management of important areas, the locking device has the purpose of enhancing the certainty of recording in the entry / exit history and the purpose of crime prevention to effectively prevent unauthorized entry or exit to the important area. It is possible to reduce the overall cost by separating these differences in purpose as differences in the unlocking operation members arranged inside and outside the room.
[0009]
In other words, it is sufficient for legitimate users who do not need to interfere with history recording to prevent entry / exit due to mistakes, and unauthorized intruders can reliably enter either by entering or leaving the room. It is considered sufficient to prevent this.
[0010]
Based on the above recognition, the present invention makes the unlocking operation member in the entrance / exit asymmetric, and uses only one of the biometrics authentication means 2 with high crime prevention performance to reduce the cost while entering / exiting the room. To increase the accuracy of management,
An entrance / exit management device for managing entrance / exit into a room closed by a door 1 that is automatically locked in an initial state,
A biometrics unlocking operation means 3 that is arranged on either the indoor side or the outdoor side and generates an unlocking signal by an authentication confirmation notification from the biometrics authentication means 2;
The non-biometrics unlocking operation means 4 is arranged on the other side and uses a match of the unlocking code given to each registrant to the biometrics authentication means 2 as a condition for generating an unlocking signal.
[0011]
In the present invention, the biometric authentication means 2 includes all of the authentication means for verifying the identity by comparing biological feature quantities such as fingerprints and retinas with previously registered feature quantities, and includes non-biometric metrics. The authentication means (non-biometric authentication means 5) used for the unlocking operation means 4 is an authentication means not based on the biometric means, such as a card carrying a password, a password, etc., and Includes all authentication means that can be associated with an authentication applicant.
[0012]
In addition, the biometrics unlocking operation means 3 only needs to include the biometrics authentication means 2, and can be used in combination with the non-biometrics authentication means 5. In this case, the non-biometrics unlocking operation means 4 is used as the biometrics unlocking operation means 4. It may be the same as or different from the non-biometrics authentication means 5 used in combination with the authentication means 2.
[0013]
Therefore, in the present invention, it is possible to reduce the overall cost by using the expensive biometric authentication means 2 only on either the entrance / exit side.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show an embodiment of an entrance / exit management device configured to be fixed directly to the door 1 and used. First, a box lock 6 provided with a dead bolt 6 a that locks and unlocks the door 1 by advancing and retracting to a strike on the door frame side is fixed to the door 1. Further, the box lock 6 accommodates a latch bolt 6b that moves forward and backward to the door frame side by an operation on the handles 7 arranged on both surfaces of the door 1 and maintains the door 1 in the closed state.
[0015]
The box lock 6 is driven by an electric drive mechanism 8 using an appropriate actuator. Further, in order to enable locking and unlocking in an emergency, a thumb turn 9 is provided on the indoor side, and a cylinder lock 10 is provided on the outdoor side. Fixed. In this embodiment, the thumb turn 9 accommodates a motor which is an actuator of the electric drive mechanism 8.
[0016]
The door 1 is provided with a door sensor 11 for detecting the opening and closing of the door 1, and a lock sensor 12 for detecting the unlocked state of the box lock 6 by the rotational position of the operation knob 9a in the thumb turn 9. Is placed.
[0017]
The entrance / exit management device is configured as a control device for the electric drive mechanism 8, and includes biometrics unlocking operation means 3 fixed to the outdoor side wall surface of the door 1 and a non-bio type fixed to the indoor side wall surface of the door 1. Metrics unlocking operation means 4.
[0018]
As shown in FIGS. 2 and 3, the biometrics unlocking operation means 3 includes a fingerprint authentication device (biometrics authentication means 2) and a password authentication means (non-biometrics authentication means 5) in the same case. Formed. On the other hand, the non-biometrics unlocking operation means 4 is constituted only by the password authentication means 5 by removing the biometrics authentication means 2 from the biometrics unlocking operation means 3.
[0019]
The operations of the biometrics unlocking operation means 3 and the non-biometrics unlocking operation means 4 are controlled by a control unit 13 accommodated in the case as shown in FIGS. Connected by cable.
[0020]
In addition, in FIG. 3, although the functional block diagram of the biometrics unlocking operation means 3 is shown in a completed state, any means having the same function as the control unit 13 on the non-biometrics unlocking operation means 4 side is selected. It is possible to provide only one control unit 13 or to concentrate all functions on one of them.
[0021]
The control unit 13 can also be configured by mounting electronic components on a mounting board, for example. However, the control unit 13 can be configured on a memory space of a microcomputer that operates according to a program stored in a ROM (not shown). Can also be realized.
[0022]
Hereinafter, the operation of the biometrics unlocking operation means 3, that is, the room entry procedure will be described based on the functional block diagram shown in FIG. 3 and the flowchart shown in FIG.
[0023]
The biometrics unlocking operation means 3 includes a password authentication means (non-biometrics authentication means 5) comprising a password input part 5a and a password determination means 5b, and a key locking / unlocking detection means 14 connected to the lock sensor 12. The code number determination means 5b and the key locking / unlocking detection means 14 are connected to the control signal generation means 16 via the bus line 15. The output monitoring from the personal identification number judging means 5b and the key locking / unlocking detecting means 14 in the control signal generating means 16 corresponds to the standby state of the biometrics unlocking operating means 3 (step S101).
[0024]
In the standby state, when the personal identification number determination unit 5b detects the input of the personal identification number to the personal identification number input unit 5a, it determines whether the inputted personal identification number is already registered (step S102), and generates a control signal. The operation start signal is notified to the means 16. Upon receipt of the operation start signal, the control signal generation means 16 instructs the bio-determination means 2a constituting the fingerprint authentication apparatus (biometrics authentication means 2) to call the authentication image corresponding to the input password. The determination unit 2a waits for a fingerprint input to the bio-authentication input unit 2b (step S103).
[0025]
From this state, when a fingerprint is input, the bio-determination means 2a compares the registered image with the input image (step S104), and if they match, outputs a verification confirmation signal to the control signal generation means 16 Then, the control signal generation means 16 notifies the lock / unlock signal generation means 17 of the generation of the unlock signal. Receiving the unlocking signal generation command, the locking / unlocking signal generating means 17 outputs the unlocking signal to the electric drive mechanism 8, and the electric drive mechanism 8 shifts the box lock 6 to the unlocked state (step S105). Thereafter, the control signal generating means 16 confirms that the key locking / unlocking detecting means 14 detects the unlocked state, and then indicates that the unlocking operation is via fingerprint authentication. 18 (step S106).
[0026]
On the other hand, when the password is input to the password input portion 5a but is different from the registered password, or after the operation start signal is output in the password determination means 5b, the fingerprint is not input, or If the input fingerprint collation result is bad, the control signal generation means 16 monitors the output of the key locking / unlocking detection means 14 in the same manner as in the standby state (step S202). When the key unlocking detection means 14 detects the shift of the lock sensor 12 to the unlocked state in the state, the control signal generating means 16 indicates that the unlocking operation is performed by directly operating the cylinder lock 10. It stores in the entrance / exit mode storage means 18 (step S202).
[0027]
After the unlocking operation is performed as described above, the control signal generation unit 16 generates a timing start command and outputs it to the timer unit 19 to start the timing operation by the timer unit 19 (step S107). The output change of the door monitoring means 20 connected to the door sensor 11 is monitored (step S108). The time measured by the timer means 19 is set to a time required for opening the unlocked door 1 and entering the room, for example, about 15 seconds.
[0028]
If the door monitoring means 20 does not detect the opening of the door 1 and the key locking / unlocking detecting means 14 does not detect the locked state before the time counting up by the timer means 19 (step S110) (step S109). The control signal generator 16 notifies the lock / unlock signal generator 17 of the generation of the lock signal and forcibly locks it (step S111).
[0029]
In order to cope with this state and the case where the door opening operation is not performed before the time is up and the key locking / unlocking detecting means 14 detects the shift to the locked state, The control signal generation means 16 stores information indicating that the unlocking operation has been performed in the entry / exit mode storage means 18 but has not been entered (step S112).
[0030]
On the other hand, when the door monitoring means 20 detects the door opening before the timer means 19 expires, information indicating that the room has entered the entry / exit mode storage means 18 is stored (step S301). It is detected from the output whether the door 1 is closed (step S302). When it is confirmed from this state that the door is closed, the locking / unlocking signal generating means 17 generates a locking signal and puts the box lock 6 in the locked state (step S303). At the same time, the operation knob 9a of the thumb turn 9 is also locked, and the shift to the unlocked state by direct operation of the thumb turn 9 from the room is prohibited.
[0031]
The thumb turn 9 is locked with such a strength that it can be rotated when a torque of a predetermined value or more is applied in order to ensure unlocking and leaving in an emergency.
[0032]
When step S112 or step S303 is completed as described above, the control signal generation unit 16 inquires of the entry / exit mode storage unit 18 about the entry mode, and stores the entry record in the entry / exit recording unit 21 based on the result. (Step S304).
[0033]
The stored information in the entry / exit recording means 21 includes all of the access history to the biometrics unlocking operation means 3 except for the case where the process is completed without performing the unlocking operation in step S201, and the entry / exit mode storage means 18 indicates that the unlocking operation is via fingerprint authentication, that is, if the information indicating that the user has entered the room is stored via step S106, the password for leaving the room registered at the time of fingerprint registration is stored. Are stored at the same time to prepare for the identification of the person entering the room and the exit process.
[0034]
Next, the operation of the non-biometrics unlocking operation means 4, that is, the leaving procedure will be described with reference to FIG. Since the non-biometrics unlocking operation means 4 has a configuration in which the biometrics authentication means 2 is simply removed from the biometrics unlocking operation means 3 shown in FIG. 3, the functional block diagram is not shown.
[0035]
First, the non-biometrics unlocking operation means 4 is in a standby state (step S401) when the password input detection state to the password input unit 5a is in the standby state (step S401), and when the exit password is input to the password input unit 5a, The personal identification number determination means 5b acquires the personal identification number for exit from the entrance / exit recording means 21 via the control signal generation means 16 and compares it with the input value (step S402).
[0036]
Thereafter, when the code number determination means 5b authenticates, the locking / unlocking signal generating means 17 generates an unlocking signal and drives the electric drive mechanism 8 in the unlocking direction to bring the box lock 6 into the unlocked state. Next, the entry / exit mode storage means 18 is written in the entry / exit mode storage means 18 to the effect that the unlocking operation has been performed with the password (step S404).
[0037]
In addition, the control signal generation means 16 monitors the state of the key unlocking detection means 14 in the standby state (step S501), and when the key unlocking detection means 14 detects the unlocked state, the abnormal unlocking has been performed. The fact is written in the entry / exit mode storage means 18 (step S502).
[0038]
As described above, when step S404 or S502 ends, the timer means 19 is activated (step S405), and then the output of the door monitoring means 20 is monitored (step S406).
[0039]
In this state, the opening operation of the door 1 is not performed before the timer means 19 times out (step S408), and the locking operation by the key locking / unlocking detecting means 14 is detected in step S407, or the timer means 19 times out. If so, a message to the effect that the user has not left the room is stored in the entry / exit mode storage means 18 (step S409).
[0040]
On the other hand, if the opening operation of the door 1 is detected in step S406 before the time is up, a message indicating that the user has left the room is written in the entry / exit mode storage means 18 (step S601), and then in step S602, the entry / exit recording means. An unusable flag is set on the exit password used by the person leaving the room 21 to disable the response to the inquiry in step S402, thereby preventing duplicate use of the exit password.
[0041]
Thereafter, the control signal generating means 16 monitors the door 1 closing operation (step S603). When the door monitoring means 20 detects that the door 1 is closed, the lock / unlock signal generating means 17 generates a lock signal to The lock state is entered (step S604).
[0042]
When step S409 or S604 is completed, the exit history is stored in the entrance / exit recording means 21 together with the exit password used by the exit (step S605).
[0043]
Note that when an operation on either the biometrics unlocking operation means 3 or the non-biometrics unlocking operation means 4 is started, the control signal generating means 16 outputs the opposite operation prohibition signal, and duplicates the operations. To prevent.
[0044]
As described above, in this embodiment, the entry / exit history is sequentially stored in the entry / exit recording means 21. This record can be displayed on, for example, an appropriate printing unit or a display device.
[0045]
In the above, the case where the biometrics unlocking operation means 3 is arranged on the outdoor side and the non-biometrics unlocking operation means 4 is arranged on the indoor side is shown, but it is also possible to reverse these positional relationships. It is. Moreover, although the case where the biometrics unlocking operation means 3 and the non-biometrics unlocking operation means 4 are directly fixed to the front and back surfaces of the door 1 is shown, it can be embedded in a wall surface or the like.
[0046]
【The invention's effect】
As is apparent from the above description, according to the present invention, the overall cost can be reduced and the operational reliability can be improved.
