An operation determining unit that determines whether the information input operation to the input device corresponds to a predetermined unauthorized unlocking operation based on the information, and the operation determining unit If it is determined as a lock operation, the security door is unlocked, the security door is unlocked when the security door opened by unlocking is closed, and the door is unlocked for predetermined exit in the security room. A lock control unit that maintains the lock of the security door when the unlocking operation for exit is detected by the sensor that detects the operation.

  According to the present invention, for example, it is possible to provide a security system capable of catching an unauthorized person by confining an unauthorized person who has entered the room through an unauthorized unlocking operation.

Embodiment 1 FIG.
FIG. 1 is a configuration diagram of a security system 1 according to the first embodiment.
The configuration of the security system 1 in the first embodiment will be described below with reference to FIG.

The security system 1 is a system that manages entry / exit of a security room 4 where entry to a specific person is restricted. When the security system 1 has illegally entered the security room 4, the unauthorized person who entered the room is confined in the security room 4, reports to the security center 2, and the security personnel who rush to the security room 4 To be caught.
In the security system 1, users who are allowed to enter the security room 4 are registered in advance, and each registered user has a contactless IC card (hereinafter referred to as an ID card) in which an ID for identifying the individual is recorded. ID card) is issued and a specific password is set. Here, the personal identification number is an example of a password and includes not only numbers but also character strings.
Hereinafter, a user registered in the security room 4 is referred to as a “registrant”.

At the entrance of the security room 4, a door 41 (security door) that is normally locked and unlocked when an unlocking operation is performed is provided.
The door 41 is attached with an electric lock that is locked and unlocked by an electric signal from the controller 3 described later.

In addition to the controller 3 (to be described later), an authentication device 33 and a password input device 34 for inputting user identification information by a user who wishes to enter the security room 4 are installed beside the door 41.
The authentication device 33 is a card reader (input device) that reads a user ID (an example of user identification information) from a user ID card.
The personal identification number input device 34 has a numeric keypad (may be a character key), and is an input device that inputs information on a key pressed by the user as a personal identification number of the user (an example of user identification information).
As an unlocking operation for the door 41 (an operation for inputting information to the input device), the user holds his / her ID card over the authentication device 33 and inputs his / her ID into the authentication device 33. The personal identification number is input to the personal identification number input device 34.

  The controller 3 (door control device) includes a control unit 31 (lock control unit, notification unit), an authentication unit 32 (operation determination unit), and a storage unit 39 (code number storage unit, identification information storage unit). It is a device that unlocks and locks an electric lock.

The authentication part 32 (operation determination part) performs the authentication process which authenticates that predetermined | prescribed unlocking operation was performed by the user using CPU. The authentication process is stored in the storage device as a program, and the operation of the authentication unit 32 described below is executed by the program and the CPU.
In the authentication process, based on the user ID read by the authentication device 33 (hereinafter referred to as the read ID 91) and the user password input to the password input device 34 (hereinafter referred to as the input password 92). The type of unlocking operation when entering the room is determined.
The types of unlocking operations upon entering the room include a predetermined “normal unlocking operation”, a predetermined “illegal unlocking operation”, and other “other unlocking operations”.

  “Normal unlocking operation” is an operation that allows entry / exit, “Unauthorized unlocking operation” is an operation that allows entry only and does not allow entry, and “Other unlocking operation” does not allow entry. It is an operation.

Based on the authentication result 93 of the authentication unit 32 and a detection signal 94 of a door sensor 35 to be described later, the control unit 31 (lock control unit, notification unit) determines whether the door 41 is unlocked or locked using the CPU. . Based on the determination result, the control unit 31 outputs the unlock signal 95 to unlock the door 41, and outputs the lock signal 96 to lock the door 41.
The door 41 unlocks the electric lock when the unlocking signal 95 is output from the control unit 31, and locks the electric lock when the locking signal 96 is output from the control unit 31.
The door sensor 35 is an infrared sensor that is installed above the door 41 in the security room 4 and detects that the user in the security room 4 stands in front of the door 41 as an unlocking operation for exit. The door sensor 35 that detects the unlocking operation for exit outputs a detection signal 94 to the control unit 31.

For example, when the authentication result 93 of the authentication unit 32 indicates “normal unlocking operation”, the control unit 31 unlocks the door 41 and opens the door 41 when the door 41 opened by unlocking is closed. The door 41 is unlocked when the detection signal 94 is output from the door sensor 35, and the door 41 is locked when the door 41 opened by the unlocking is closed. As a result, the user who has performed a normal unlocking operation when entering the room can enter the security room 4 and leave the security room 4.
Further, for example, when the authentication result 93 of the authentication unit 32 indicates “other unlocking operation”, the control unit 31 does not unlock the door 41 and keeps the door 41 locked. The locked door 41 is not opened. Thereby, a user who does not perform a predetermined unlocking operation (normal unlocking operation or unauthorized unlocking operation) when entering the room can be prevented from entering the security room 4.
Further, for example, when the authentication result 93 of the authentication unit 32 indicates “unauthorized unlocking operation”, the control unit 31 unlocks the door 41 and opens the door 41 when the door 41 opened by the unlocking is closed. The door 41 is kept locked when the detection signal 94 is output from the door sensor 35. The locked door 41 is not opened. Further, the control unit 31 transmits a detection signal 94 for notifying the presence of an unauthorized person to the center device 21 installed in the security center 2. Thereby, a user who has performed an unauthorized unlocking operation when entering the room can enter the security room 4, be confined in the security room 4, and be captured by a security guard rushed from the security center 2.

In the storage unit 39 (password number storage unit, identification information storage unit), a registration ID 39a, a normal operation code number 39b, and an unauthorized operation code number 39c are associated with each registrant and registered in advance. .
The storage unit 39 stores the registration ID 39a, the normal operation password 39b, and the unauthorized operation password 39c of each registrant using a storage device (for example, a semiconductor memory or a magnetic disk device).

  The input operation in which the input code number 92 matches the registrant's normal operation code number 39b is “normal unlocking operation”, and the input code number 92 matches the registrant's unauthorized operation code number 39c. The operation is an “unauthorized unlocking operation”, the input operation without the registration ID 39a that matches the reading ID 91, and the input password 92 that does not match the normal operation password 39b or the unauthorized operation password 39c of the registrant. The operation is “other unlocking operation”.

In the security center 2, a security device is stationed and a center device 21 that communicates with the controller 3 of the door 41 is installed. The controller 3 of the door 41 and the center device 21 of the security center 2 are connected by wire or wireless via a communication network such as a LAN, the Internet, and a telephone line network.
When the alarm notification 97 is transmitted from the control unit 31 of the controller 3, the center device 21 confirms that there is an unauthorized person in the security room 4 by displaying an alarm message on the display or outputting an alarm sound from the speaker. Notify security guards.
The security guard notified of the presence of the unauthorized person rushes to the security room 4, opens the door 41 by a predetermined method (for example, normal unlocking operation), and detects the unauthorized person trapped in the security room 4. capture.

FIG. 2 is a flowchart showing a door control method of security system 1 according to the first embodiment.
The door control method of the security system 1 according to the first embodiment will be described below with reference to FIG.
Each unit of the controller 3 executes processing described below using a CPU.
The processing procedure described below is stored as a program in the storage device, and the program is executed by the CPU and OS.

In the security system 1, if a registrant registered in the security system 1 is asked for an ID card and a personal identification number in response to a threat from an unauthorized person trying to enter the security room 4, the personal identification number for normal operation is used. The unauthorized operation code number 39c is transmitted to the unauthorized person instead of 39b.
The unauthorized person attempts to enter the security room 4 using the ID card that has been stolen and the password that has been heard (password for unauthorized operation 39c).

<S110>
Users (including the unauthorized persons described above) who wish to enter the security room 4 hold the ID card over the authentication device 33 installed on the side of the door 41 as an unlocking operation for the door 41, and further, a password The PIN code is entered by pressing the numeric keypad of the number input device 34.
The authentication device 33 detects a radio wave from a nearby ID card. The authentication device 33 that detects the radio wave from the ID card reads the ID recorded on the ID card and outputs the read ID to the authentication unit 32 as the read ID 91.
The personal identification number input device 34 outputs the pressed numeric keypad information to the authentication unit 32 as the input personal identification number 92.
The authentication unit 32 inputs the reading ID 91 output from the authentication device 33 and also inputs the input password 92 output from the password input device 34, and resolves based on the input reading ID 91 and the input password 92. Authenticate the lock operation.

As the authentication process, the following process is executed by the authentication unit 32.
The authentication unit 32 searches the storage unit 39 and determines whether there is a registration ID 39 a that matches the reading ID 91. Hereinafter, the registration ID 39a that matches the reading ID 91 is referred to as “user registration ID 39a”.
When the user registration ID 39a is present, the authentication unit 32 refers to the normal operation code number 39b and the unauthorized operation code number 39c stored in the storage unit 39 in association with the user registration ID 39a. It is determined whether the personal identification number 92 matches the normal operation personal identification number 39b or the unauthorized operation personal identification number 39c.

When there is a user registration ID 39a and the registration ID 39a matches the normal operation code number 39b, the authentication unit 32 authenticates that the “normal unlocking operation” has been performed by the user.
When the user registration ID 39a is present and the registration ID 39a matches the unauthorized operation code number 39c, the authentication unit 32 authenticates that an “unauthorized unlocking operation” has been performed by the user.
When there is no user registration ID 39a, the authentication unit 32 authenticates that the “other unlocking operation” has been performed by the user.
If the registration ID 39a does not match either the normal operation code number 39b or the unauthorized operation code number 39c, the authentication unit 32 authenticates that the user has performed “another unlocking operation”.
After the authentication process, the authentication unit 32 outputs an authentication result 93 indicating the authenticated unlocking operation to the control unit 31.

  The unlocking operation by the unauthorized person is “unauthorized unlocking operation” because the input password 92 is the password for unauthorized operation 39c. That is, when an unlocking operation is performed by an unauthorized person, the authentication result 93 indicates “unauthorized unlocking operation”.

<S120>
The control unit 31 inputs the authentication result 93 output from the authentication unit 32 in S110, and determines whether the authentication result 93 indicates “normal unlocking operation”.
If the authentication result 93 indicates “normal unlocking operation” (“Yes”), the process proceeds to S121. If the authentication result 93 does not indicate “normal unlocking operation” (“No”), the process proceeds to S130. Proceed to

<S121>
When the authentication result 93 indicates “normal unlocking operation” in S 120 (“Yes”), the control unit 31 outputs an unlock signal 95 to the door 41.
Upon receiving the unlock signal 95, the door 41 unlocks the electric lock, opens the door, and closes the door after a predetermined time.
The user enters the security room 4 while the door 41 is open.
After S121, the process proceeds to S140.

<S130>
When the authentication result 93 does not indicate “normal unlocking operation” in S120 (“No”), the control unit 31 determines whether the authentication result 93 indicates “illegal unlocking operation”.
When the authentication result 93 indicates “unauthorized unlocking operation” (“Yes”), the process proceeds to S131.
Further, when the authentication result 93 does not indicate “unauthorized unlocking operation” (“No”), that is, when the authentication result 93 indicates “other unlocking operation”, the door 41 is not unlocked and the process is performed. finish.
At this time, since the door 41 is not unlocked, the user cannot enter the security room 4. This prevents entry of a user who does not have an ID card or a user whose password is unknown, and can maintain security.

<S131>
When the authentication result 93 indicates “unauthorized unlocking operation” in S130 (“Yes”), the control unit 31 outputs the unlocking signal 95, and the door 41 is unlocked / opened, as in S121. The person (illegal person) enters the security room 4 and the door 41 closes.
After S131, the process proceeds to S132.

<S132>
When the authentication result 93 indicates “unauthorized unlocking operation” in S130 (“Yes”), the control unit 31 displays an alarm notification 97 indicating that “unauthorized unlocking operation” has been performed in the center of the security center 2. To the device 21.
The center device 21 that has received the alarm notification 97 from the control unit 31 of the controller 3 notifies the security guard that the “unauthorized unlocking operation” has been performed by display display or alarm sound output.
The security guard who receives the notification from the center device 21 rushes to the security room 4.
After S132, the process proceeds to S133.

<S133>
In S130, when the authentication result 93 indicates “unauthorized unlocking operation” (“Yes”), the control unit 31 sets a leaving flag indicating whether or not the user can leave the room to “unable to leave”. It is assumed that the initial value of the leaving flag indicates “leaving available”, and the leaving flag is stored in advance in the storage device.
That is, when an unauthorized person enters the security room 4, the exit flag indicates “no exit”.
After S133, the process proceeds to S140.

  S131 to S133 do not need to be performed in the above order and are not in any order.

<S140>
When the door 41 is unlocked, opened and closed in S121 or S131, the control unit 31 outputs a locking signal 96 to the door 41, and the door 41 receiving the locking signal 96 locks the electric lock. For example, the door 41 includes a sensor that detects door closing, and the sensor outputs a door closing detection signal to the control unit 31, and the control unit 31 outputs a locking signal 96 when receiving the door closing detection signal.
However, the lock signal 96 may not be output from the control unit 31, and the door 41 that detects the door closing may be autonomously locked. In this case, the unlock signal 95 from the control unit 31 to the door 41 in S121 and S131 means an unlock instruction and a lock instruction after the door is closed.
After S140, the process proceeds to S150.

<S150>
A user (registrant) who entered the security room 4 by “normal unlocking operation” and a user (unauthorized person) who entered the security room 4 by “unauthorized unlocking operation” will leave the security room 4. In front of the door 41.
The door sensor 35 installed in the upper part of the door 41 in the security room 4 outputs a detection signal 94 to the control unit 31 of the controller 3 when detecting a user who appears in front of the door 41. The controller 31 of the controller 3 receives the detection signal 94 output from the door sensor 35.
After S150, the process proceeds to S160.

<S160>
The control unit 31 of the controller 3 that has input the detection signal 94 in S150 refers to the leaving flag and determines whether the user can leave the room.
When the leaving flag indicates “cannot leave” (“Yes”), that is, when an unauthorized person enters the security room 4, the door 41 is not unlocked, and the process ends.

At this time, since the door 41 is not unlocked, an unauthorized person cannot leave the security room 4 and is confined in the security room 4.
And the security guard who rushed from the security center 2 in S132 opens the door 41 by a predetermined method, and captures an unauthorized person in the security room 4.
As a result, an unauthorized person who has entered the security room 4 can be caught, other persons can be given up on the unauthorized entry into the security room 4, the unauthorized entry can be suppressed, and the security of the security room 4 can be improved.

<S161>
When the exit flag indicates “can be exited” (“No”), that is, when the registrant enters the security room 4, the control unit 31 outputs the unlock signal 95 and the door 41 is unlocked as in S121. Lock and open the door, and the registrant leaves the security room 4.
After S161, the process proceeds to S162.

<S162>
After S161, the door 41 locks an electric lock in the same manner as S140, and the process ends.

In the above description, a “card reader” that reads an ID from an ID card is used as the authentication device 33. However, the authentication device 33 may be an input device other than the “card reader”.
For example, the authentication device 33 may be a device that acquires biometric information of a user such as a fingerprint, finger vein, voice print, iris, and face image.

  Further, the authentication device 33 may not be provided. At this time, the authentication unit 32 of the controller 3 determines that the input operation when the input code number 92 matches any one of the normal operation code numbers 39b is a “normal unlocking operation”. The input operation in the case of matching with the unauthorized operation code number 39c is determined as an “unauthorized unlocking operation”, and the input code number 92 matches any of the normal operation code number 39b and the unauthorized operation code number 39c. The input operation when not performing is determined as “other unlocking operation”. Here, it is assumed that there is no overlapping password in the normal operation password 39b and the unauthorized operation password 39c.

Moreover, although the user standing in front of the door 41 and having the door sensor 35 detect it was described as an unlocking operation for exiting, the unlocking operation for exiting is not limited thereto.
For example, rotation of a door knob provided on the door 41 or depression of a door opening button provided on the door 41 may be an unlocking operation for exit. The door sensor 35 is built in the door 41 and detects rotation of the door knob or pressing of the door opening button as an unlocking operation for exit.
Further, for example, the security room 4 is also provided with an input device such as the authentication device 33 and the password input device 34, and the identification information such as the ID and the password is given to the user as an unlocking operation for leaving, as in the case of entering the room. May be input.
In this case, when the leaving flag indicates “leaving is allowed” and the identification information input to the input device in the security room 4 is registered, the door 41 is unlocked, and the registrant is removed from the security room 4. You can leave the room. Even if the leaving flag indicates “leaving allowed”, if the identification information input to the input device in the security room 4 is not registered, the door 41 is not unlocked, and the registrant leaves the security room 4. Can not. When the exit flag indicates “no exit”, the door 41 is not unlocked regardless of whether or not the identification information input to the input device in the security room 4 is registered, and an unauthorized person cannot leave the security room 4. . The input device installed in the security room 4 corresponds to the door sensor 35 that detects the unlocking operation for leaving the room, and detects the input of the identification information as the unlocking operation for leaving.

  The center device 21 may not be a computer but an alarm device such as a buzzer or a rotating lamp. The alarm device that has received the alarm notification 97 signal sounds an alarm buzzer or turns on to notify the security guard that an entry has occurred due to an unauthorized release operation.

In the first embodiment, the following security system 1 has been described.
When the security system 1 determines that the unlocking operation performed by the user is an unauthorized operation, the security system 1 permits entry into the room and notifies the center device 21 of the security center 2 of an alarm, and enters the room by an unauthorized operation. Control the door so that you cannot leave the room. That is, the security system 1 performs traffic control so as not to be unlocked when a person who performs an illegal operation enters the room and then the person leaves the room.
Specifically, two security codes, a normal operation code number 39b and an unauthorized operation code number 39c, are registered in the security system 1, and the security system 1 is passed using the unauthorized operation code number 39c. Is recognized as unauthorized traffic due to unauthorized operations.
As a result, the person who enters the room by performing an unauthorized operation cannot be left, and the person who performed the unauthorized operation can be caught by the guard who has been alerted.

Embodiment 2. FIG.
In the first embodiment, the input of the registration ID 39a and the normal operation password 39b is “normal unlocking operation”, the input of the registration ID 39a and the unauthorized operation password 39c is “unauthorized unlocking operation”, Others were described as “other unlocking operations”.
However, the unlocking operations different from those in the first embodiment may be “normal unlocking operation”, “illegal unlocking operation”, and “other unlocking operations”.
In the second embodiment, examples of “normal unlocking operation”, “illegal unlocking operation”, and “other unlocking operations” different from the first embodiment will be described. Other matters are the same as those in the first embodiment.

<Example 1>
The unlocking operation is determined based on whether or not a predetermined number of pieces of identification information has been input.
For example, it is assumed that the registered password number is one (normal operation password number 39b). And the authentication part 32 of the controller 3 determines unlocking operation by whether both ID and the PIN code were input.
The input of both the ID and the personal identification number is “normal unlocking operation”, and the input of either the ID or personal identification number is “unauthorized unlocking operation”. It is assumed that the ID and password entered in “normal unlocking operation” and “unauthorized unlocking operation” match those registered. The input of an unregistered ID and password is referred to as “other unlocking operation”.
In the case of an intimidation by an unauthorized person, the registrant tells the unauthorized person only either the ID or the password, or inputs only the ID or the password. As a result, the unauthorized person enters the security room 4 by an unauthorized unlocking operation. And the security system 1 can confine the unauthorized person who entered the room in the security room 4, notify the security guard, and let the guard who rushed to catch the unauthorized person.

<Example 2>
The unlocking operation is determined based on whether or not the ID card used for inputting the ID has been reported as lost.
For example, only the authentication device 33 is provided as an input device for identification information. If the registrant reports loss, the administrator issues an ID card in which a new registration ID 39a is recorded to the registrant, and the ID attribute recorded in the lost old ID card is registered. “ID” is changed to “lost ID”. Then, the authentication unit 32 of the controller 3 determines the unlocking operation based on whether the ID (read ID 91) input to the authentication device 33 is the registration ID 39a or the lost ID.
The registration ID input is “normal unlocking operation”, the lost ID input is “illegal unlocking operation”, and the other ID input is “other unlocking operation”.
As a result, the security system 1 locks an unauthorized person who has entered the security room 4 by an unauthorized unlocking operation using the stolen ID card in the security room 4, reports to the security guard, and sends an unauthorized person to the guard Can be captured.

<Example 3>
The unlocking operation is determined based on the input order of the plurality of identification information.
For example, it is assumed that the registered password number is one (normal operation password number 39b). Then, the authentication unit 32 of the controller 3 determines the unlocking operation based on the input order of the ID and the personal identification number (the output order of the reading ID 91 and the input personal identification number 92 to the authentication unit 32).
Input in the order of ID-> PIN (or PIN-> ID) is "normal unlocking operation", and input in the sequence of PIN-> ID (or ID-> password) is "illegal unlocking operation" And It is assumed that the ID and password entered in “normal unlocking operation” and “unauthorized unlocking operation” match those registered. The input of an ID and a password that are not registered is “other unlocking operation”.
Further, for example, only the personal identification number input device 34 is provided as an identification information input device, and two personal identification numbers, the personal identification number A and the personal identification number B (both are the normal operation personal identification number 39b) are registered. Then, the authentication unit 32 of the controller 3 determines the unlocking operation based on the input order of the two passwords input to the password input device 34.
The input in the order of the password number A → the password number B is “normal unlocking operation”, the input in the order of the password number B → the password number A is “unauthorized unlocking operation”, and the password numbers A and B It is assumed that the input of two passwords other than the combination of “other unlock operations”.
When an unauthorized person is threatened, the registrant informs the unauthorized person of an incorrect input order as the input order of the ID or password, or inputs the ID or password in the incorrect input order. Thereby, the unauthorized person enters the security room 4 by an unauthorized unlocking operation. And the security system 1 can confine the unauthorized person who entered the room in the security room 4, notify the security guard, and let the guard who rushed to catch the unauthorized person.

<Example 4>
The unlocking operation is determined by the input method of the password.
For example, only the personal identification number input device 34 is provided as an input device for identification information. In addition, the user strongly presses or holds down the numeric keypad (or the enter key after entering the password) at least once when entering the password. And the authentication part 32 of the controller 3 determines unlocking operation based on the presence or absence of the input by the strong press of a key, and the presence or absence of the input by the long press of a key. The password input device 34 includes a pressure sensor and a timer, measures the pressure applied to the pressed key by the pressure sensor, and measures the continuous pressing time during which the key is continuously pressed by the timer. The authentication unit 32 of the controller 3 determines that there is an input by pressing the key strongly when the pressure value measured by the personal identification number input device 34 is equal to or greater than a predetermined value, and the continuous measurement measured by the personal identification number input device 34. When the pressing time is equal to or greater than a predetermined value, it is determined that there is an input by long pressing of the key.
An input with a key press or key press more than a predetermined number of times is defined as "normal unlocking operation", and an input with no key press or key press for a specified number of times is referred to as "Unauthorized unlocking operation". " It is assumed that the password entered in “normal unlocking operation” and “illegal unlocking operation” matches the registered one. The input of an ID and a password that are not registered is “other unlocking operation”.
When an unauthorized person is intimidated, the registrant inputs a password by reducing the number of key presses and key presses less than a predetermined number of times. As a result, the unauthorized person enters the security room 4 by an unauthorized unlocking operation. And the security system 1 can confine the unauthorized person who entered the room in the security room 4, notify the security guard, and let the guard who rushed to catch the unauthorized person.

“Input value (password)” in the first embodiment, “number of inputs” in the first embodiment of the second embodiment, “input value (ID)” in the second embodiment, “input order” in the third embodiment, implementation In Example 4, the form in which “input method (strong press, long press)” is normally used as a condition for an unauthorized or other unlocking operation has been described.
However, the conditions for the unlocking operation may be other conditions.
Each condition may be combined.
For example, if the conditions of all the combined “normal unlocking operations” are met, “normal unlocking operation” is set, and if not satisfying at least one of the combined “normal unlocking operations” conditions, "Unlocking operation". The input values of “normal unlocking operation” and “illegal unlocking operation” are assumed to match those registered. The input of unregistered information is referred to as “other unlocking operation”.

For example, the condition of the first embodiment (password attribute) may be combined with the condition of the second embodiment (ID attribute) of the second embodiment.
At this time, the authentication unit 32 of the controller 3 determines that the case where the reading ID 91 is “registration ID 39a” and the input personal identification number 92 is “normal operation personal identification number 39b” as “normal unlocking operation”.
Further, the authentication unit 32 of the controller 3 determines that the reading ID 91 is “lost ID” and the input code number 92 is “normal operation code number 39b” or “unauthorized operation code number 39c”, and the reading ID 91 is “registered”.
