Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal identification medium such as a magnetic card, a card with a bar code, and a non-contact card, and a biometric feature such as a fingerprint and a retinal pattern. The present invention relates to an entry / exit management system that identifies a person who enters or exits, determines whether or not entry / exit is possible, and issues an alarm when a door as an entry / exit management gate is open for a long time or when the door is pry open.

[0002]

2. Description of the Related Art Access control systems are widely used from financial institutions and energy-related facilities to general buildings and some apartments in recent years. As a medium for personal identification, magnetic cards containing personal information are generally used, but contactless cards with higher security performance are also increasing, and in some cases cards with barcodes, fingerprint verification, retina and Verification of biological characteristics such as vein patterns is also used.

FIGS. 2 to 4 show an example of an access control system using a generally used magnetic card (which stores personal identification information) as a medium.

FIG. 2 shows a general access control system.

In FIG. 2, 1 is a first room, 2 is a magnetic card reader (personal identification device) for restricting access to the first room 1, and 3 is a door (access control gate) of the first room 1. , 4 is a second room, 5 is a magnetic card reader for managing access to the second room 4, 6 is an electric lock attached to a door (access control gate) of the second room 4. A lock 7 is a computer, 8 is a cable connecting between the magnetic card readers 2 and 5 and connecting the magnetic card reader 5 to the computer 7, and 9-1 is an electric lock 3 attached to a door of the first room 1 and the computer 7 Connecting cable, 9
Reference numeral -2 denotes a cable connecting the electric lock 6 attached to the door of the second room 4 and the computer 7.

The communication between the magnetic card readers 2 and 5 and the communication between the magnetic card reader 5 and the computer 7 may have a relatively long distance.
Alternatively, RS485 is often used. When a magnetic card is passed through the card reader 2 (or 5), personal information (personal identification information) stored in the magnetic card is read,
The computer 7 determines whether or not the owner of the magnetic card has the right to pass through the door, and if the owner can pass the door, the electric lock 3 (or 6) is driven to the unlocked state. Of course, the cardholder can turn the door knob to open the door and enter room 1 (or 4).

When the door is an automatic door, the automatic door is opened instead of being unlocked.

[0008] The criterion for judging whether or not passing is assumed to be a magnetic card registered in the system.
In addition, restrictions or regulations are often made on the time zone to be passed, the day of the week, and the doors that can be passed, and the degree of the restriction is often called an access level, a card level, or the like.

FIG. 3 is a system diagram of communication between the magnetic card reader and the computer when the number of magnetic card readers increases in the system of FIG. The magnetic card readers No. 1, No. 2 to No. m, and No. n having individual addresses are connected to the computer 7 by a communication line, and the computer 7 sequentially connects the magnetic card readers No. 1 to No. n. The card data is received by polling, and the function of the magnetic card reader is set. As described above, the form in which the computer 7 and the magnetic card readers No. 1 to No. n directly communicate is often performed by a relatively small-scale system. In FIG. 3, No. 1 is a magnetic card reader having an address "1", No. 2
No. to No. m and No. n are magnetic card readers having addresses "2" to "m" and "n", respectively, and 8 'is a magnetic card reader between No. 1 to No. n and a magnetic card reader No. n. And a communication cable between the computer 7.

In a relatively small access control system, the computer 7 directly polls the magnetic card readers No. 1 to No. n in the system structure of FIG. As the number increases, the time required for polling all magnetic card readers increases, resulting in deterioration of the response of the card verification.

From the point of view of the card holder, the time from when the card reading operation is performed to when the result is displayed is generally within 0.5 seconds at most in general, and the time required for the result is about 1 second. It is said that the person feels too late and, after two seconds, clearly feels out of tolerance. Card readers are installed at the entrances and exits of the entire building and are sometimes used for attendance management. However, an increase in polling time is a great barrier to a request to read card data of many people at once.

The system shown in FIG. 3 is used when the computer 7 breaks down or when the computer 7 and the card readers No. 1 to N
When an error occurs in the communication line with the o.n, the function of the entire system is stopped.

FIG. 4 shows that a card controller 10 for independently managing the magnetic card readers 2 and 5 is provided between the computer 7 and the magnetic card readers 2 and 5.
This is a conventional example in which a card controller 10 'for independently managing the magnetic card readers 2' and 5 'is provided between the computer 7 and the magnetic card readers 2' and 5 '.

In FIG. 4, 1 is the first room,
2 is a magnetic card reader (personal identification device) for restricting access to the first room 1, 3 is an electric lock attached to the door of the first room 1, 4 is the second room, 5 is the second room. A magnetic card reader for controlling access to the room 4; 6, an electric lock attached to the door of the second room 4;
5-1 is a cable connecting the magnetic card reader 5 to the card controller 10, 9-1 is a cable connecting the electric lock 3 attached to the door of the first room 1 to the card controller 10, and 9-2 is a cable connecting the The cable connects the electric lock 6 attached to the door of the second room 4 to the card controller 10.

In FIG. 4, 1 'is a third room,
2 ′ is a magnetic card reader (personal identification device) for restricting access to the third room 1 ′, 3 ′ is an electric lock attached to the door of the third room 1 ′, 4 ′ is the fourth room, 5 'is the fourth
Card reader to control entry and exit to room 4 ', 6'
Is an electric lock attached to the door of the fourth room 4 ', 8'
Is a cable connecting between the magnetic card readers 2 'and 5' and between the magnetic card reader 5 'and the card controller 10';9'-1 is an electric lock 3 'attached to a door of the third room 1' and a card controller. Reference numeral 9'-2 denotes a cable connecting the electric lock 6 'attached to the door of the fourth room 4 and the card controller 10'.

Reference numeral 19 denotes a communication cable between the card controller 10 and the computer 7, and 19 'denotes a communication cable between the card controller 10' and the computer 7.

The computer 7 is equipped with management software.

Between magnetic card readers 2 and 5, between magnetic card reader 5 and card controller 10, between card controller 10 and computer 7, between magnetic card readers 2 'and 5', between magnetic card reader 5 'and card controller 10' , Card controller 10 '
And the computer 7 may have a relatively long distance.
485 is often used.

In FIG. 4, the card controllers 10 and 1
0 'incorporates a CPU (Central Processing Unit),
The card data of the entire system or the card data of a person who can operate the magnetic card reader assigned to the card controller is stored in the memory, and the magnetic card reader is sequentially polled to receive the card data,
It determines whether or not the magnetic card data can pass through the door, performs operations such as driving an electric lock and turning on a display lamp, and sends the result to the computer 7. In many cases, when the door is kept open for a long time, or when the door is pryed open, it is detected and sent to a computer.

In the system shown in FIG. 4, the computer 7
Poll card controllers 10 and 10 ',
The determination results of the card controllers 10 and 10 'may be captured and displayed on a screen or saved on a disk. Even if the system becomes large-scale and the number of card controllers increases, the response of the card reading may not be sufficient. Become irrelevant.

In FIG. 4, the response of the card operation depends on the polling performed by the card controller to each card reader. Therefore, if the number of card readers assigned to the card controller is noted, the card can be operated regardless of the cost of advancement. The response of the operation can be kept constant.

Furthermore, since card data is stored in each card controller, and whether or not the card holder can pass is determined by the card controller alone, when a failure occurs in the computer or communication between the computer and the card controller becomes abnormal. Card operation is performed normally even when the error occurs. Many card controllers have the function of temporarily storing data to be sent to the computer in case of the above-mentioned accident.If a card controller with such a function is used, data that cannot be transmitted due to the accident can be deleted. Since the data can be stored in the card controller, if the accident recovers within a certain period of time, the data stored in the card controller can be sent together to the computer,
Therefore, loss of data during an accident can be prevented.

FIG. 5 is a conceptual diagram of the operation of the card controller 10 of the system shown in FIG. The operation concept is basically the same for the card controller 10 'of the system shown in FIG. 4 and for the computer 7 of the system shown in FIG.

In FIG. 5, No. 1 is a magnetic card reader having an address of "1", and No. 2 to No. n are each "2".
A magnetic card reader having an address of "n", K
(1) an electric lock drive output unit that operates when the magnetic card reader No. 1 reads regular card data;
(2) to K (n) are magnetic card reader Nos. 2 to N, respectively.
o.n is an electric lock drive output unit that operates when the card data is read, and 20 is a determination unit that compares the read card data with the card data and determines whether the person can pass through the door. It is.

In FIG. 5, the magnetic card readers No. 1 to No. n are connected in cascade by an RS485 compliant communication line, and the card controller 10 corresponds to the addresses of the magnetic card readers No. 1 to No. n. It has an electric lock drive output unit. In this example, the electric lock drive output is a voltage via a closed relay contact, but a separate electric lock control panel is provided,
The card controller may output an operation signal of the electric lock control panel. The magnetic card reader has an output section of a display LED, an electric lock, an input section of a door status signal, and the like, in addition to those shown in FIG. 5, but is omitted in FIG. The number of electric lock drive output units provided in the card controller 10 is 4
The number of card controllers 10 is set to 〜8. This is because, in the case of a medium-sized or larger office building, the number of doors used for access control on one floor is often about 4 to 8.

The operation of the access control system using a magnetic card will be described with reference to FIGS.

For ease of explanation, the address of the magnetic card reader 2 in FIG. 4 is "1", the address of the magnetic card reader 5 is "2", the address of the magnetic card reader 2 'is "3", It is assumed that the address of the card reader 5 'is "4".

A person “A” who has a legitimate magnetic card and tries to enter the first room 1 in FIG. 4 operates the magnetic card reader 2. The magnetic card reader 2 holds the read card data, and when polling of the card controller 10 is received, sends the held card data to the card controller 10. The determination unit 20 (FIG. 5) of the card controller 10 compares the received card data with regular card data stored in the card controller 10, and if the received card data is determined to be regular card data, The electric lock drive output unit K (1) to operate is operated. The electric lock 3 in FIG. 4 is unlocked by the output of K (1),
The authorized card holder "A" can enter the room 1. If the card held by “A” is not a regular card, the determination unit 20 of the card controller 7 does not operate the electric lock drive output unit K (1),
“A” cannot enter Room 1. The operation is the same when trying to enter the second room 4 and when entering the third and fourth rooms 1 'and 4'.

In this embodiment, the case where a magnetic card is used as a personal identification medium is described. However, even if an IC card, a contactless card, or a personal identification number is used, a fingerprint or voice such as a fingerprint or voice can be used as a personal identification element. The operation of the system is the same whether biometric features are used or some personal identification methods are used together.

[0030]

The problem of the prior art described above is that one electric lock drive output unit (K (1) to K (n) is provided for one address of the magnetic card readers No. 1 to No. n. )).

In the entry / exit management system for a particularly important area or dangerous area, not only a time when entering a room is managed by a magnetic card reader (personal identification device) for management but also when leaving the room. Some are managed by an outgoing management magnetic card reader (personal identification device). For example, in a very important place, when it is desired to keep the time in the area below a certain level, or when there is a dangerous substance and it is desired to always know who is inside. In addition, there may be a case where the user wants to know who was last and when it was last, such as when upgrading the security by raising the user's awareness.

Further, a magnetic card reader (personal identification device) for a healthy person and a magnetic card reader (personal identification device) for a physically handicapped person are attached to the same door while changing the position in the height direction. In addition, the number of healthy persons and persons with physical disabilities using the same door has been increasing.

In such a case, even if any of the entry management magnetic card reader and the exit management magnetic card reader is operated, a magnetic card reader for a healthy person and a magnetic card reader for a disabled person are operated. Regardless of which of the magnetic card readers is operated, if the read card data is valid, it is necessary to drive the same electric lock to open the door.

Conventionally, in such a case, the outputs of two electric lock driving units corresponding to a magnetic card reader for entrance management and a magnetic card reader for exit management are connected in parallel, or a magnetic card reader for a healthy person is used. The outputs of two electric lock driving units corresponding to a card reader and a magnetic card reader for the physically handicapped are connected in parallel, and the same electric lock is driven even if either magnetic card reader reads the regular card data. Was like that.

FIG. 6 shows an example in which one electric lock is driven by the outputs of two magnetic card readers.

In FIG. 6, reference numeral 2 denotes an entry management magnetic card reader operated when entering room 1, and reference numeral 11 denotes an exit management magnetic card reader operated when exiting room 1. Between the magnetic card reader 11 and the magnetic card reader 2 and between the magnetic card reader 2 and the determination unit 2 of the card controller 10
0 'is connected by a communication cable 8. In the card controller 10, K (2) is an electric lock driving unit corresponding to the magnetic card reader 2, and K (11) is an electric lock driving unit corresponding to the magnetic card reader 11. The determination unit 20 ′ of the card controller 10 includes the magnetic card reader 2
It is determined whether or not the card data read by (or 11) is valid, and the magnetic card reader 2 (or 1)
If the card data read in 1) is legitimate,
The electric lock driving unit K (2) (or K (11)) is operated. Here, the electric lock driving units K (2) and K (11)
Are externally connected in parallel so that one of the electric locks 3 is driven regardless of which operation is performed.

As described above, even when one electric lock is driven by any operation of a plurality of card readers, a system as shown in FIG. 6 has been realized. However, since there is actually no relationship between multiple card readers, a combination of which card reader is used for "in" in which room and which card reader is used for "out" in which room Must be performed for each individual system, and at the same time, when creating computer management software,
It was necessary to set the card reader, door name, entry / exit, etc. for each system, which was troublesome, and hindered standardization of management software and reduction of cost.

In the case of a system for managing "entry" and "out", two electric lock driving units are used for one door and one electric lock, so that eight electric lock driving units are used. In the case of a card controller with a, when used in a system that manages "out" and "in", only four electric locks can be driven, and two card controllers are required to manage eight doors turn into.

Further, when the system is provided with an anti-passback function, there is no coordination between the address of the "entry" magnetic card reader and the address of the "out" card reader for a certain door. The definition of "in" and "out" had to be done in the computer's management software settings, which was time-consuming and expensive.

In particular, when planning and constructing a system, management of only “entrance” to a room was performed. However, management of both “entrance” and “departure” was changed at a later date due to a change in purpose of use. If it is changed to do so, a card controller must be added with the addition of a card reader,
In addition to the work required to add a card controller, the relationship between the card reader and the door of the management software has also been re-established, and the time required for adding and changing both hardware and software, or for the construction work is large. Met.

An object of the present invention is to provide a controller capable of effectively using an electric lock driving unit and an access control system including the controller.

According to the present invention, an address for connecting a plurality of personal identification devices (card readers) to one electric lock driving unit is set in advance, and the addresses of the plurality of personal identification devices are associated with each other, so that the conventional electronic lock drive is complicated. Was "out"
It is an object of the present invention to provide a system that can construct a system for managing entry and exit at the same design cost and time as an access control system that manages only entrance.

Further, the present invention makes it possible to easily create an environment in which, for example, a healthy person and a person in a wheelchair can use the same access control system without stress by giving meaning to the address of the personal identification device. The purpose is to provide a system that can do it.

Furthermore, the present invention does not require the addition of hardware such as a controller even when the access control system for managing only "entrance" is changed to a system for managing "exit" and "entry". It is an object of the present invention to provide an access control system that can achieve its purpose inexpensively and in a short period of time only by adding an identification device and making minor changes in operation software.
