2. Description of the Related Art Conventionally, in order to secure security of a company or a store, there is a system in which an employee owns a magnetic card and performs access control. In the access control system using the magnetic card, a card reader for reading information of the magnetic card is installed at an entrance door of each security area (for example, a floor or a room) to be restricted, and the card reader is installed. It is common practice to compare the information read by the computer with the information stored in advance in the verification device, and control the unlocking of the electric lock provided at the entrance door of each security area according to the verification result. I have.

[0003] When the access control is performed by collating the information stored in the magnetic card with the information stored in the collation device, the card reader is provided in a security zone where the card reader is installed. Is stored in the magnetic card, and the collation device stores the owner identification information for uniquely identifying each employee in association with the owner identification information. In many cases, an employee to whom the owner identification information is assigned is stored with area identification information for specifying a security area to which entry and exit are permitted. Here, a processing procedure for performing access control using such information will be briefly described.

When a card reader reads a magnetic card by an operation of an employee, the card reader transmits the owner identification information stored on the magnetic card and the area identification information given to the card reader to a collating apparatus. Then, the collation device collates, based on the received owner identification information and the area identification information, whether or not the area identification information is stored in association with the owner identification information. As a result of this collation, if the zone identification information is stored, an entry / exit permission signal is transmitted to the card reader to unlock the electric lock of the entrance door, and conversely, if the zone identification information is not stored , An unlocking signal is transmitted to reject the unlocking of the electric lock.

[0005]

However, in the above-mentioned prior art, the amount of information to be stored in the verification device becomes enormous, so that the work of registering the information becomes complicated and whether or not entry and exit is permitted. There is a problem that the speed of collating is reduced.

[0006] That is, the above-mentioned prior art needs to store the zone identification information of all security zones to which entry and exit are permitted for all employees who own the card.

06 is permitted to enter and exit all the security areas A to C, and the owner identification information "000"
FIG. 6 shows a case where an employee of “2” is permitted to enter and exit the security area A and the security area C, and an employee of the owner identification information “0003” is permitted to enter and exit the security area C.
It is necessary to store the owner identification information and the area identification information as shown in FIG.

In the access control of a company or a store, in general, a combination of an employee who is not permitted to enter and leave and a security area (owner identification information "0002" and "000" shown in FIG. 6)
3) and a combination of an employee who is allowed to enter and exit from the security area (owner identification information “0001”, “00” shown in FIG. 6)
04 "and" 0006 "), the amount of information to be stored in the verification device naturally increases in accordance with the number of issued cards and the number of security zones in the above-described conventional technology. For this reason, in the case of a company with a large number of employees or a store with a large number of security zones, the amount of information to be stored in the verification device becomes enormous, and the work of registering the information becomes complicated, and entry and exit are permitted. There is a problem in that the speed of checking whether or not to perform is reduced.

Therefore, the present invention has been made to solve the above-mentioned problems of the prior art, and prevents an increase in the amount of information to be registered in a matching device, thereby reducing the labor required for information registration. It is an object of the present invention to provide an access control system that can reduce the number of times and can quickly check whether to permit access.

The description will be made in association with the instruction creation.

The collation unit 37a collates whether or not the zone identification information included in the collation data is stored in the zone identification information DB 31. If the zone identification information is not stored, the instruction creation unit 3
7b creates an instruction for displaying a reading error on the display unit 13 of the reading device 10.

The collating unit 37a determines that the number of digits of the attribute information and the owner identification information included in the collation data is the attribute information D
B32 and the number of digits of each piece of information stored in the disapproval information DB 33 are compared to see if they match, and if they do not match,
The command creating unit 37b creates an unlocking non-permission signal for rejecting unlocking, assuming that the card is not a legally issued card.

The collating unit 37a verifies whether the attribute information included in the collation data is stored in the attribute information DB 32. If the attribute information is not stored, the instruction creating unit 3a
7b is not a legally issued card,
Create an unlocking permission signal for rejecting unlocking.

The collation unit 37a determines that the owner identification information and the area identification information contained in the collation data are the non-permission information D.
It is checked whether or not it is stored in B33, and if it is not stored, the signal creation unit 37b creates an unlocking permission signal for permitting unlocking. On the other hand, the disapproval information DB3
If it is stored in No. 3, an unlocking non-permission signal for rejecting unlocking is created. In this case, an unlocking abnormality signal to be transmitted to the monitoring center 40 is also created.

Further, the owner identification information and the area identification information included in the collation data are stored in the non-permission information DB 33, and the stored information restricts entry into all security areas, that is, a card lost. If this is caused by the above, the command creating unit 37b creates a degaussing signal for degaussing the magnetic information of the card 1.

Each signal created by the instruction creating section 37b in this way is transmitted to the reading device 10 via the first transmitting / receiving section 35.
The processing of the reading device 10 and the processing of the monitoring camera 20 are performed based on these various signals.
