Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a room entry / exit restriction device for a room requiring security (security room) such as a computer room, a research room, and a design room.

With the progress of the highly information-oriented society, the demand for the safety of security rooms is ever increasing. In order to improve the safety of the security room, it is basically necessary to check for unauthorized entry, and it is important to actually prevent entry and exit by unauthorized persons.

[0003]

2. Description of the Related Art Conventionally, a general security room entrance / exit restriction device is composed of a door provided at the entrance of the security room and an electric lock for locking the door.

An electric lock is generally an input section such as an ID card reader or a personal identification code input key, and identification information for judging whether or not a person is permitted to enter the room based on the identification information read by the input section. The determination unit and the drive unit that unlocks the door or drives the door to open according to the unlock signal from the identification information determination unit.

To enter the security room, ID
Those who have performed the necessary prescribed procedures such as sliding the card to read it with an ID card reader or inputting a personal identification code from the key, and having the identification information or personal identification code etc. permitted to enter the security room. Is a condition. Otherwise, you cannot enter the security room.

[0006]

However, in the conventional entry / exit control device for the security room, when the electric lock is unlocked and the door is opened, a plurality of consecutive persons can enter and exit. Therefore, there is a possibility that an unauthorized occupant may enter the room while the door is open immediately after the legal occupant enters the room through the formal procedure.

To solve this problem, for example, the door for entering the security room is doubled, and an independent check room is provided between these two doors, and a person who enters the check room It is conceivable to control the second door so that the second door can be unlocked only when it is confirmed by the sensor that there is only one person.

However, in such a case, a large area is occupied for the independent check room,
In addition, it is necessary to fundamentally remodel the structure of the existing room, such as installing two doors for completely closing the check room, resulting in a large scale of the entire apparatus and a large cost. Moreover, since it takes time to confirm the number of people in the check room with the sensor, there is a problem that the number of people who can pass in a unit time decreases.

In view of the above problems, the present invention provides a device for restricting entry / exit to a security room, which does not become a large-scale device and can effectively prohibit an unauthorized person from entering the room at a relatively low cost. The purpose is to do.

[0010]

In order to solve the above-mentioned problems, an apparatus according to the invention of claim 1 is provided at the entrance of a security room SR as shown in FIGS. The first main door 11 and the second main door 12 each have an electric lock, and the electricity of the first main door 11 is changed according to the identification information issued by the occupant. The first identification information determination unit 72a for unlocking the lock and the first identification information determination unit 72a arranged inside the first main door 11 with a waiting space WSA in which one person can wait. The gate flapper 24, a second identification information determination unit 72b for opening the first gate flapper 24 in response to the identification information issued by a person waiting in the waiting space WSA, and the second main door. The second gate flapper 25, which is arranged on the indoor side of 12 and has a waiting space WSB in which one person can wait, and the second gate flapper 25 is opened according to the identification information issued by the person. It is configured to have a third identification information determination unit 72c for operating and unlocking the electric lock of the second main door 12.

The apparatus according to the second aspect of the present invention has an in-room detection sensor 32 for detecting the presence or absence of an in-room person in the waiting space WSB on the second main door 12 side,
The second main door 12 is configured to be opened when the occupant detection sensor 32 detects an occupant.

The apparatus according to the third aspect of the present invention comprises a fourth identification information judging section 72d for unlocking the electric lock of the second main door 12 in accordance with the identification information issued by the occupant, and the second identification information judging section 72d. A fifth identification information determination unit 72e for opening the second gate flapper 25 in accordance with the identification information issued by the person who enters the waiting space WSB on the main door 12 side.
And a sixth identification information determination section 72f for opening the first gate flapper 24 and unlocking the electric lock of the first main door 11 in accordance with the identification information issued by the occupant. Composed.

[0013]

The person entering the security room SR can pass through the first main door 11 by issuing the identification information such as the ID card or the personal identification code, and then the same or different identification information as before is displayed. By emitting the light, it becomes possible to pass through the first gate flapper 24, and these enable entry into the room.

Further, a person in the security room SR can leave the room by passing the second gate flapper 25 and the second main door 12 by issuing the identification information.

Since a person entering the room temporarily waits in the waiting space WSA, a plurality of people cannot pass through the entry / exit restriction device 1 continuously. To enter an unauthorized room,
Since it is necessary to approach a legitimate person in the room very closely, it is revealed by the legitimate person to prevent the illegal person from entering the room.

In the present specification, the term “person entering the room” includes a person who is actually entering the room, a person who is planning to enter the room, a person who is planning to leave the room, and the like.

2 is attached.

Although not shown in the drawings, the main body terminals 21 and 22 are provided with sensors for detecting the number of people who enter the room and the number of people who pass each time, and the first and second gate flappers 24 and 25 swing. A sensor or the like is provided to detect that the action has been taken.

The first main door 11 and the second main door 12 are controlled by a control unit 70, which will be described later, and are automatically opened and closed. In addition, the first gate flapper 24 and the second gate flapper 25 include the control unit 70.
The opening / closing driving force is not so strong, and it is possible for an occupant to block the operation against the driving force. However, in that case, the alarm lamps LAR and LBR are turned on and the alarm buzzer BZ sounds.

The control unit 70 uses the above-mentioned card reader A1.
To A3 and B1 to B3, first and second main doors 1
1st door drive part 81 and 2nd door drive part 82 which drive 1 and 12, respectively, 1st and 2nd gate flapper 2
It is composed of a first gate driving section 83 and a second gate driving section 84 for respectively driving the Nos. 4 and 25, and a discrimination control section 71.

The discriminating control unit 71 includes card readers A1 to A
3 and identification information CA1 to CA3, CB from B1 to B3
1 to CB3 is determined, the number of the card reader that issued the identification information, and the occupant detection sensor 3
Based on the detection statuses of 1, 32, the status of other various sensors (not shown), and the history up to that point, the first
A command signal S is sent to the door drive unit 81, the second door drive unit 82, the first gate drive unit 83, or the second gate drive unit 84.

The discrimination control unit 71 also compulsorily opens the first gate flapper 24 or the second gate flapper 25, or when a plurality of people pass through while opening the alarm lamps LAR, LBR. Is turned on and the alarm buzzer BZ is sounded.

By operating the emergency switch 33 provided on the center terminal 23, all the doors and gates can be unlocked so that they can be automatically opened or manually opened.

Further, by operating the opening switches 34 and 35 provided on the body terminals 21 and 22 respectively, the doors and gates on the respective sides are unlocked so that the doors and gates can be automatically opened or manually opened. Is possible
A large number of people such as visitors can pass in one direction.
The mode switch 41 is for switching the operation mode of the discrimination control unit 71.

The discrimination control unit 71 as described above can be easily realized by using a ROM, a CPU, peripheral elements, etc., which are appropriately programmed to perform control according to the algorithm shown in this embodiment.

Next, the operation of the room entry / exit restriction device 1 configured as described above will be described. In normal times, the mode selector switch 41 switches to the one-way mode. In the one-way mode, the first main door 11 operates exclusively for entering the room and the second main door 12 operates exclusively for exiting the room. Therefore, even if the ID card is input to the card readers A3, B1 and B2, it does not operate.

In the one-way mode, a person who wants to enter the security room SR (a person who enters the room) slides the ID card on the card reader A1 to read it.
The discrimination control unit 71 uses the identification information C from the card reader A1.
If A1 is valid, the command signal S1 for opening the first main door 11 is output to the first door driving unit 81.

When the first main door 11 is opened, the occupant advances along the arrow M1 to the waiting space WSA, where the same ID card is slid on the card reader A2 to be read. When the identification information CA2 from the card reader A2 is valid, the discrimination control unit 71 outputs a command signal S3 for opening the first gate flapper 24 to the first gate drive unit 83.

When the first gate flapper 24 is opened in the direction of arrow M4, the person entering the room enters the security room SR. The first main door 11 is closed when the occupant advances to the waiting space WSA or after a certain period of time after opening, and the first gate flapper 24 is used when the occupant advances to the security room SR or Open and close after a period of time.

When the person entering the room leaves the security room SR, the ID card is slid on the card reader B3 to be read. When the identification information CB3 from the card reader B3 is valid, the discrimination control unit 71 instructs the second gate driving unit 84 to send the second gate flapper 2 to the second gate flapper 2.
Command signal S4 for opening 5 and second door drive unit 8
2 outputs a command signal S2 for opening the second main door 12.

Since the second gate flapper 25 opens in the direction of the arrow M4 and the second main door 12 subsequently opens, the occupant exits the outdoor OD. The second gate flapper 25 is closed when a person who has entered the waiting space WSB or after a certain period of time has opened, and the second main door 12 is opened or opened when the person has entered the outdoor OD. Close after a certain period of time. Note that the second main door 12 may be opened when the occupant reaches the waiting space WSB.

In each of the above cases, the identification information CA2
Passable display lamp L when each CB3 is valid
AG and LBG light up. Further, the identification information CA1, CA
If 2 and CB3 are not valid, the corresponding door or gate is not opened.

When the entering person is in the waiting space WSA, the identification information CA2 becomes improper for some reason, or when the entering person is erroneously entered or the legitimate identification information CA2 cannot be output because of an unauthorized entering person as described later. In order to prevent being trapped in the waiting space WSA, a person entering the room or an unauthorized person can move in the direction of the arrow M3 to reach the waiting space WSB, and at the time when the waiting space WSB is reached. This is detected by the in-room detection sensor 32, whereby the second main door 12 is automatically opened and can be taken out to the outdoor OD.

Next, a description will be given of a case where there is an unauthorized intruder who attempts to enter the room in the one-way mode, followed by a legitimate intruder. As mentioned above, the first
The first main door 11 is closed when the main door 11 is moved to the waiting space WSA, so that an unauthorized person can be basically prevented from entering the room. That is, in order for an unauthorized person to enter the room, he / she must pass through the first main door 11 and the first gate flapper 24 in a state of being extremely close to the legal person, but in such a case, An unauthorized person will be revealed as an unauthorized person. In particular, the waiting space WSA is large enough for one person to wait, so if a legitimate person and an illegal person live there, they will come into contact with each other. Unauthorized persons are definitely revealed and excluded by legitimate persons.

Further, if a legitimate in-room person passes through the first gate flapper 24 immediately after passing through a certain timing gap, an illegal in-room person can successfully wait in the waiting space WSA.
Even if the user has proceeded to (1), the unauthorized person cannot pass the first gate flapper 24 because it cannot output the identification information CA2 for opening the first gate flapper 24.

When the first gate flapper 24 is forcibly opened and passed, the alarm lamp LAR lights up and the alarm buzzer BZ sounds, so that it is revealed by the person in the security room SR. Therefore, in this case, there is no choice for the unauthorized person to move in the direction of arrow M3,
Then, the second main door 12 can be opened to enter the outdoor OD. However, this is for the wrong person.

If there is an unauthorized person in the security room SR, the unauthorized person will enter the outside O
In order to leave D, the second gate flapper 25 and the second main door 12 should be in close proximity to a legitimate person.
However, in such a case, a legitimate person who enters the room reveals that he / she is an unauthorized person.

Thus, according to the entrance / exit restriction device 1,
An unauthorized person can be effectively prevented from entering or leaving the room. Further, since a person entering the room can enter the room by advancing in the traveling direction and reading the ID card twice, the time required for entering the room is small, and a large number of people can pass in a unit time.

Next, when it is necessary to pass a large number of people within a short time such as in a meeting, the mode changeover switch 41 is used to switch to the bidirectional traffic mode.
In the two-way traffic mode, the first main door 11 and the second main door 11
Both main doors 12 operate for both entry and exit.

In the bidirectional traffic mode, the card readers B1 and B2 are used for entering the room, and the card reader A3 is used for exiting the room. Since each operation is the same as that described above, description thereof is omitted here.

As described above, since the entrance / exit control device 1 is set in the bidirectional traffic mode, two passages are formed both in the entrance and exit, so that the number of people who can pass in a unit time is almost double that in the one-pass mode. can do.

When an abnormal situation such as a fire occurs in the security room SR, the emergency switch 33 can be operated to easily and quickly exit the room.

In the above embodiment, the first main door 11 and the second main door 12 are described as automatic doors. However, for example, only the electric lock is automatically unlocked during the opening operation. The opening operation may be manually performed by a person who enters the room.

In the above-described embodiment, a key for allowing a person entering the room to input a personal identification code may be provided instead of or together with the card reader. In addition, the configuration of each part of the entrance / exit restriction device 1, such as the gate device 13 and the control unit 70, can be variously changed.

[0049]

According to the first aspect of the present invention, it is possible to effectively prevent an unauthorized person from entering the room at a relatively low cost without using a large-scale device.

According to the second aspect of the present invention, it is possible to prevent a person who accidentally enters the waiting space from being trapped. According to the invention of claim 3, two passages are formed both for entry and exit, so that the number of people who can pass in a unit time can be further increased.
