Description

  The present invention uses a personal identification medium such as a magnetic card, a card with a bar code, or a contactless card to identify a person who goes in and out of a place where the frequency of going in and out is low, such as a general home, an apartment, or a specific important place. In addition, the present invention relates to an entry / exit management system that determines whether entry / exit is possible or issues an alarm when the door is open for a long time or when it is opened.

  An entry / exit management system is disclosed in Patent Document 1, for example.

Access control systems are widely used from financial institutions and energy related facilities to general buildings and some apartment buildings in recent years. Conventionally, magnetic cards were generally used as personal identification media, but contactless cards with higher security performance are also increasing. Some cards with barcodes, fingerprint verification, retina and vein patterns, etc. It is also used to check biometric features. Among them, contactless cards are not only high security,
-Since the card reader does not have a mechanism, it can be maintenance-free.
-Reads data just by bringing the card closer to the card reader, so there is no need to remove it from the bag etc.
・ Excellent environmental friendliness because it is not easily affected by rain, snow, etc.
Has many features and has been used a lot.

  In an entrance / exit management system such as a building, the door to be managed is always closed from the viewpoint of security. When the door is unlocked using a personal identification medium such as a card and the door is passed, the door is automatically closed by a door closer. A mechanism is used that closes.

  This system is effective in cases where people outside the room, such as office buildings, usually enter a room that requires security and come out when the use is completed, and entry into a room is given specific authority. Only the cardholder is allowed, and the security of the room is protected.

  Since many offices and facilities are under such usage conditions, most conventional card systems are constructed based on the above operations.

  On the other hand, in general households, residents are usually in their homes, go out for shopping, work, etc., and return to their rooms when they are done. Also, unlike offices, it is often used in situations where there are no other people around, such as living alone.

  In this case, if you forget to have a card when you leave the house, and you exit the door and the door closes automatically, you will never be able to enter the house again. In some places, such as offices, you work in a room that is almost all day long, and you get out of that room only when you have a job. It may happen that you cannot enter the room until the next person comes.

  Therefore, if the frequency of entry / exit is small and the number of people entering / exiting is very small, such as a part of a general home or office, a viewpoint different from the conventional entrance / exit management system (card system). It is necessary to review including security.

JP 2001-241226 A

  The present invention proposes a new entrance / exit management system (card system) based on a different idea from the conventional entrance / exit management system (card system) for offices.

  In other words, an object of the present invention is to read and store card data by a card reader when going out, so that the electric lock becomes a locking operation, preventing the user from forgetting to carry the card when going out and improving the security performance ( Card system).

  The access control system according to the present invention is as follows.

  According to the present invention, when the user goes out, the card reader reads the data of the card, so that the electric lock becomes a locking operation, prevents the user from forgetting to hold the card when going out, and improves the security performance (card system). ) Is obtained.

  Next, embodiments of the present invention will be described with reference to the drawings.

  Hereinafter, the present invention will be described taking the case of using a contactless card as an example, but the card used is not limited to a contactless card, as long as it is a card that can identify an individual such as a magnetic card or a card with a barcode, The same effect as when a contactless card is used can be expected.

  First, a general access control system will be described with reference to FIG. 1 for better understanding of the present invention.

  The entrance / exit management system of FIG. 1 is an entrance / exit management system (card system) using a contactless card as a personal identification medium, and FIG. 2 is a block diagram of the entrance / exit management system of FIG.

  In FIG. 1, 1 is a door (entrance / exit management gate) that is an entrance of a managed room, 2 is a contactless card reader, and 3 is an electric lock installed on the door.

  A closer is attached to the door 1 so that the opened door 1 is naturally closed. This is to prevent the door 1 from being left open after a person has passed.

  The non-contact card reader 2 is installed at a height at which a card in the vicinity of the door 1 is easily held, generally 1200 mm to 1500 mm from the floor.

  In FIG. 2, 2 is a contactless card reader, 22 is a contactless card registered in the system, 23 is a controller, 3 is an electric lock attached to the door 1 (FIG. 1), and 5 is a management PC (Personal Computer). ). Card data of the contactless card 22 is registered in a memory (not shown) in the controller 23.

  The non-contact card reader 1 is in a posture to constantly read card data, reads the data of the approached card almost instantaneously, and transmits the data to the controller 23. The controller 23 stores registered card data therein, and collates and determines whether the card data sent from the card reader 2 is already registered. As a result of the determination, if the sent card data is already registered and the setting is such that it can pass through the door 1, the controller 23 drives the electric lock 3 for a certain period of time and unlocks it. The received card data is transmitted to the management PC 5. The management PC 5 retrieves the card holder from the card data and displays the card holder on the screen.

  The time for which the controller 23 drives the electric lock 3 is set to several seconds to several tens of seconds. When the driving time of the electric lock 3 elapses, the electric lock 3 is locked again. In many such systems, in addition to the cardholder's pass information, the door can be opened and the electric lock 3 can be broken, the door 1 can be opened and the like can be displayed.

  Some simple systems omit the controller 23 and check the card data with the card reader 2 or the management PC 5, and there are systems in which the electric lock 3 is driven with the card reader 2 or the management PC 5. .

  As described above, in a general system, a system is often constructed on the assumption that a managed room is entered from the outside. Therefore, the card reader 2 is installed on the entrance side, and most of them can be freely turned by turning the knob of the door 1 when leaving the room. In such a general system, it is mainly to enter a room managed using a card from the outside, so that a person who forgets the card can take measures such as returning to the card.

  Considering the case where such a card system as an entrance / exit management system is installed in a condominium or a general home, the resident does not necessarily have to have a card in the room. You will use a card to enter the room.

  That is, if you forget to have your card when you go out, you will not be able to enter the room when you go home. If you have a family member in your house when you come home, you can talk on the intercom and unlock it from the inside, but there is no way to unlock the single person or when you are away from home.

  If a manager is stationed in a condominium, etc., you can have a valid card in all the houses and go out without a key, but you can ask the manager to open it, but it is cumbersome and increases management tasks Invite. Furthermore, in general houses and the like, it is necessary to take measures such as providing a means for opening the door (for example, a cylinder lock) when going out without holding the card, and the security of the card system may be impaired.

  In addition, when such a card system is widely used in condominiums and general households, the card reader 2 is always in a card reading posture when the above-described system is used. It is also conceivable that a crime involving unlocking at a certain probability using a device that sequentially transmits possible data at a high speed may be established.

  Therefore, according to the present invention, when the card reader reads the data of the card, the electric lock becomes a locking operation, and the card data reading operation and the unlocking confirmation operation by the card reader are performed within a predetermined time. Provided is an access control system (card system) that prevents the user from forgetting to hold a card when going out and improves security performance by unlocking the lock.

  FIG. 3 shows an access control system (card system) according to the first embodiment of the present invention, and FIG. 4 is a block diagram of the access control system (card system) of FIG. The access control system (card system) according to the first embodiment shown in FIGS. 3 and 4 is indicated by the same reference numerals as the access control system (card system) shown in FIGS. Includes similar parts.

  That is, in FIG. 3, 1 is a door (entrance / exit management gate) which is an entrance of a room such as an apartment, 2 is a non-contact card reader, 3 is an electric lock installed on the door 1, and 4 is a means for unlocking confirmation operation. There is a push button.

  In FIG. 4, 1 is a contactless card reader, 22 is a contactless card registered in the system, 33 is a controller, 3 is an electric lock attached to the door 1, 5 is a management PC, and 4 is an unlock confirmation. In many cases, the management PC 5 is omitted in a simple system using a push button as an operation means. Wires 7 are connected between the controller 33 and the non-contact card reader 2, between the controller 33 and the electric lock 3, between the controller 33 and the push button 4, and between the controller 33 and the management PC 5. Yes. When operated, the push button 4 is an operation unit that outputs a signal, gives the signal to the controller 33, and notifies the controller of the operation.

  The door 1 is locked by an electric lock 3, but can be freely opened from the inside by turning a knob.

  The controller 33 has the following functions.

(1) Contactless card registration and deletion functions.
(2) A function of checking the data of the contactless card with the registered data and unlocking the electric lock 3 for a predetermined time in the case of the registered data.
(3) A function of receiving an unlocking signal of the electric lock 3 and an opening signal of the door 1.
(4) A function for issuing an alarm when the electric lock 3 is broken, when the door 1 is opened, or when the door 1 is opened.
(5) Entrance record keeping function (can be confirmed on the screen when the PC 5 is connected, and is not an indispensable element for implementing the present invention).
(6) Power backup battery at power failure.

  The operation under the control of the controller 33 of this embodiment will be described with reference to FIG.

  In the example described below, a case will be described in which the unlocking of the electric lock 3 is performed by causing the card reader 2 to read the card data after performing the unlocking confirmation operation. The same effect can be obtained even in the system 3 for unlocking.

  When going out, the resident in this room opens the door 1 to go outside, closes the door 1, brings the card close to the non-contact card reader 2, reads the card data, and locks the electric lock 3.

  At this time, the green lamp of the card reader 2 is turned on and a beeping sound is emitted to notify the cardholder of the lock. When the card reader 2 reads the card data while the electric lock 3 is already locked, a re-locking operation is not performed, and a “beep” sound is generated and a green lamp is lit. It is preferable in terms of security.

  In the unlikely event that the lock 3 cannot be locked due to a malfunction of the electric lock 3, a malfunction is indicated by a continuous buzzer sound "Pee".

  When returning home, press the push button (unlock confirmation operation button) 4, bring the card close to the card reader 2 within a certain time (set from several seconds to several tens of seconds), read the card data, and press the electric lock 3 You can unlock and enter the room. Here, when the card data is read, the red lamp of the card reader 2 is turned on, and at the same time, a beep sound is emitted to inform the card holder of the unlocking.

  The push button (unlock confirmation operation button) 4 may be provided with a lamp indicating that it can be unlocked for a certain period of time. Instead of the lamp and buzzer, “locked” “unlocked” “card” You may make a sound such as "Please move closer."

  In addition, the card data reading operation of the card reader 2 is performed for a certain period of time after the door 1 is closed (this is also set to several seconds to several tens of seconds) and for a certain period of time from the unlocking confirmation operation (as described above, several seconds to several tens of seconds) If it is limited to the above, it is preferable in terms of security, and the burden on the power backup battery can be reduced.

  Furthermore, if the card reader 2 reads the card data and stops reading the card for a certain period of time (set to several seconds to several tens of seconds), the risk of a crime using a plurality of picked up cards indiscriminately can be reduced.

  In the above example, the order in which the card data is read after pressing the push button 4 that is the unlocking confirmation means has been described, but the same applies to the order in which the push button 4 that is the unlocking confirmation means is operated after the card data is read. An effect is obtained.

  According to the first embodiment, since the lock cannot be performed when the card is forgotten, the resident must always go out with the card and prevent the card from being forgotten. Further, according to the first embodiment, since it is not necessary to attach a keyhole to the door 1, it is possible to prevent an act of unlocking from the keyhole. Furthermore, according to the first embodiment, since the unlocking confirmation operation must be performed every time the unlocking operation is performed, a crime that aims at unlocking at a certain probability by sequentially transmitting the expected card data at a high speed. Can be prevented.

  FIG. 5 shows an access control system (card system) according to the second embodiment of the present invention, and FIG. 6 is a diagram for explaining the operation of the knob 51 of the access control system (card system) of FIG. The access control system (card system) according to the second embodiment shown in FIGS. 5 and 6 is the same as the access control system (card system) shown in FIGS. 1 and 2, and FIG. 3 and FIG. It includes similar parts indicated by the same reference numerals as the access control system (card system) shown.

  In particular, in FIGS. 5 and 6, the second embodiment of the present invention utilizes the operation of turning the knob 51 of the door (in / out management gate) 1 as the unlocking confirmation operation.

  As shown in FIG. 6, in the second embodiment, a switch 63 attached to the inside of the door 1 and interlocking with the knob 51 is used instead of the push button 4 of FIGS. 3 and 4. Except for this point, the second embodiment is the same as the first embodiment (FIGS. 3 and 4). That is, the second embodiment has a circuit configuration represented by a block diagram similar to that of FIG. 4 except that a switch 63 interlocked with the knob 51 is used instead of the push button 4. That is, the switch 63 is operated as shown in the lower diagram of FIG. 6 by turning the knob 51 to output a signal, and the signal is given to the controller 33 (FIG. 4) via the wire 64. It is an operation part which notifies that it was operated in (FIG. 4).

  In FIG. 6, 51 is a knob attached to the door 1, 62 is a bar that moves in conjunction with the rotation of the knob 51, 63 is the above-described switch, 64 is a wire, and 65 is a spring. .

  Normally, as shown in the upper diagram of FIG. 6, the bar 62 is lowered by the tension of the spring 65, and the switch 63 is off.

  When the knob 51 is turned to the right, as shown in the lower diagram of FIG. 6, the bar 2 also rotates in conjunction with it, pushes the switch 63 to output a signal to the switch 63, and sends the signal to the controller 33 (FIG. 4). ) To inform the controller 33 (FIG. 4) that it has been operated.

  Originally, since the unlocking operation is performed by the electric lock 3, the operation of turning the knob 51 is not necessarily required (some are required depending on the type of the electric lock). Therefore, even if a handle such as a handle is attached to the door 1 in place of the conventional knob 51, the function is not hindered. However, natural operation is possible by using the knob 51.

  That is, in FIGS. 5 and 6, a person who tries to open the door 1 brings the card close to the card reader 2 and reads data. Thereafter, when the knob 51 of the door 1 is turned within a predetermined time, the switch 63 built in the door 1 is turned on, and the electric lock 3 is unlocked by the controller, so that the door 1 can be opened.

  Next, an access control system (card system) according to a third embodiment of the present invention will be described with reference to FIG. 7, FIG. 8, and FIG. The access control system (card system) according to the third embodiment described with reference to FIGS. 7, 8, and 9 is the access control system (card system) shown in FIG. 1 and FIG. The same part shown with the same referential mark as the access control system (card system) shown in FIG.3 and FIG.4 is included.

  In the third embodiment, the call button of the intercom entrance cordless handset is used as an unlocking confirmation switch.

  In order to attach a new switch for unlocking confirmation to an existing building, the construction cost, including wiring from the room to the outside, will not be stupid.

  Also, the design tends to be uncomfortable with the surroundings.

  In the third embodiment, an intercom call switch is used as an unlocking confirmation means, thereby making it possible to create a system that is not uncomfortable in design at a low cost.

  FIG. 7 shows an intercom entrance cordless handset used in the third embodiment, FIG. 8 is a block diagram of an access control system (card system) according to the third embodiment, and FIG. 9 shows an interphone used in the third embodiment. It is a circuit diagram for demonstrating operation | movement of an entrance child machine.

  In FIG. 7, 71 is a call button, and 72 is a speaker microphone.

  When used as a normal interphone, when the call button 71 is pressed, a chime sounds in the room to notify the visitor, and the speaker microphone 72 communicates with the room.

  In FIG. 8, 2 is a contactless card reader, 22 is a contactless card registered in the system, 33 'is a controller, 3 is an electric lock attached to a door (in / out management gate), 5 is a management PC, 86 Is a relay that operates when the non-contact card reader 2 reads card data. In a simple system, the management PC 5 is often omitted. Wires 7 are connected between the controller 33 ′ and the non-contact card reader 2, between the controller 33 ′ and the electric lock 3, between the controller 33 ′ and the relay 86, and between the controller 33 and the management PC 5. Has been.

  The controller 33 'registers card data in the same manner as the controller 33 (FIG. 4). The controller 33 ′ operates the relay 86 when the card reader 2 reads the registered card data.

  When the relay 86 is operated, the relay contact RY of FIG. 9 is moved, and the circuit is switched from the intercom master to the controller 33 '. In FIG. 9, COM is a common line.

  8 and 9, in the third embodiment, when the controller 33 'reads the card data registered in the card reader 2, the call button circuit of the entrance unit is transferred from the intercom master to the controller 33'. Since switching is performed, a chime does not sound even if the call button 71 is pressed, and instead, if the call button 71 is pressed, the potential of the common line COM is supplied to the controller 33 ′. The controller 33 ′ unlocks the electric lock 3 when the potential of the common line COM is supplied within a predetermined time after the card reader 2 reads the registered card data. As described above, when the call button 71 is operated, it acts as an operation unit that applies the potential of the common line COM to the controller 33 'and notifies the controller 33' of the operation.

  That is, in FIG. 8 and FIG. 9, a person who tries to open the door brings the card close to the card reader 2 and reads data. Thereafter, when the call button 71 is pressed within a certain time, the electric lock 3 is unlocked by the controller 33 'and the door can be opened.

  Next, an access control system (card system) according to a fourth embodiment of the present invention will be described with reference to FIG.

  In the fourth embodiment, as shown in FIG. 10, a card reader 2 incorporated in a housing (case) of an intercom entrance cordless handset is used. The fourth embodiment is different from the third embodiment described above in this point. Otherwise, the fourth embodiment is the same as the third embodiment.

  When installing an entry / exit management system using cards, a card reader must be installed near the door to be managed (entrance / exit management gate).

  In a conventional entrance / exit management system such as an office, even if it is installed in an existing building, in the case of an office, the partition is often a plate wall or a partition, and it is often not difficult to install. In addition, there are many places where the card reader 2 is attached in the vicinity of the door in the building, and it is often unnecessary to pay much attention to the appearance design.

  However, in general houses and condominiums, the card reader 2 is often attached to the outer wall near the entrance door, and the conventional card reader 2 is attached with a large amount of work such as processing the outer wall such as concrete and opening a wire through hole. Construction was necessary. In terms of design, the back-attached conduits are often exposed on the wall surface, which is detrimental to the aesthetics. Also, the cost of the installation work significantly exceeds the price of the card reader 2 in terms of cost. This has hindered the spread of the card system 2.

  In the fourth embodiment, the components of the card reader 2 are integrated with the intercom entrance unit to greatly reduce the installation work and cost of the card reader 2, thereby reducing the high security performance of the card system at a low cost. It is possible to provide in.

  FIG. 10 shows an example of the structure of a card reader integrated with an entrance unit used in the fourth embodiment. FIG. 10 shows an antenna coil of the card reader 2 in particular. The operation of the fourth embodiment is similar to the operation of the third embodiment described above.

  The electronic parts used for the card reader 2 are not so difficult to be accommodated in the case of the entrance unit.

  By applying the fourth embodiment, the installation of the card reader 2, which has become a large scale in the past, is made to connect the power source and the signal line of the card reader 2 using the through hole of the entrance unit. It is a simple operation that simply replaces the entrance door unit with the card reader integrated type and does not bring about any significant changes in design.

  Furthermore, by using the unlocking confirmation switch also as the call switch 71 of the entrance cordless handset, the unlocking confirmation switch is provided in the immediate vicinity of the card reader 2, so that it is possible to provide a more manageable entrance / exit management system.

  As described above, by using the present invention, it is possible to provide high security performance and convenience of a card access control system at a low cost. In addition, since the lock is realized by reading the card data, it is possible to provide a system from the user's standpoint, such as preventing the card from being forgotten.

  In the figure, the contactless card reader and the controller are illustrated separately. However, in a small-scale system, the contactless card reader can have a controller function.
