Description

[Detailed Description of the Invention] The present invention relates to a verification management device that uses a verification medium such as a card, and is intended to improve its verification management function.

An example in which the present invention is applied to an electronic door opening/closing device will be described below.

FIG. 1 shows the door opening/closing device of this embodiment. In this device, in order to prove the validity of the person entering the room, the person entering the room carries a card 1 on which a code unique to the person entering the room is recorded, and when entering the room, inserts the card 1 into a card reader 2 installed near the entrance. When inserted, the verification means 3 verifies the contents of the card read by the card reader 2 under the predetermined verification conditions, and when the validity of the card, that is, the person entering the room, is verified by the verification means 3, the door 4 is opened.
This makes it possible to open up the world. There are a plurality of rooms to be managed, and the above-mentioned device is placed in each of these rooms.

As shown in FIG. 2, the card 1 records a registration number code 5 of the person entering the room as a unique code, and an entry permission code 6 corresponding to each individual's work and responsibility. In particular, the latter code is specifically 1 to
It represents 10 importance levels (10 being the most important); for example, if a person's entry permission code is "2", that person is the 9th most important person. Note that the format in which each of the above codes is recorded on the card 1 cannot be deciphered by the human eye; for example, the optimal format is to represent each number as a coded figure, and to make each of these figures into a hologram and arrange them on the card. .

The registration number code of the card read by the card reader 2 is input to the matching circuit 7 as a BCD code (binary coded decimal code). The matching circuit 7 searches for individual registration number codes in a storage device 8 that stores individual registration number codes of many people entering the room.
When the registration number code inputted from the card reader 2 is found therein, a verification signal A is output.

On the other hand, the entry permission code of the card read by the card reader 2 is input to the comparison circuit 9 as a BCD code. For the reference input of the comparison circuit, an entry permission level is set in the entry permission level setting circuit 10 according to the importance of the room whose entry is to be controlled, and the entry permission code from the card is set as the entry permission level. When the level is equal to or greater than the level, the comparison circuit 9 outputs the verification signal B. The above room entry permission level is the importance level (1 to 1) assigned to the person.
10).

Verification signal A from matching circuit 7 and verification signal B from comparison circuit 9 pass through AND gate 11 and become final verification signal C.

The monostable multi 12 is triggered by the final verification signal C and generates a drive signal D for a certain period of time, and controls the electromagnetic lock controller 13 of the door 4 with this signal. That is, while the drive signal D is present, the electromagnetic locking mechanism that locks the door 4 is opened, allowing the door 4 to be opened.

Furthermore, such an electromagnetic lock mechanism can be used as an automatic door mechanism.
It is also possible to automatically open the door 4 while the drive signal D is present.

Therefore, according to the above device, when the registration number code of card 1 is sure to be the registered one, verification signal A is generated, and the entry permission code of card 1 is uniquely set for that room (door). Verification signal B is generated when the level is equal to or greater than the entered entry permission level, and final verification signal C is generated only when both signals A and B are generated at the same time, indicating that the door 4 can be opened or has been opened. , you can enter the room. As a result, for example, the fourth important person who has an entry permission code of "7" can enter all the rooms of importance from 1 to 7. Further, by setting the setting level of the entry permission level setting circuit 10 to "1", it is possible to allow all persons to enter the room.

As is clear from the above explanation, in the device of the present invention, permission to use (enter) the controlled object is granted based on the magnitude relationship between the importance level recorded on the card and the importance level set for the controlled object. Therefore, by simply changing the importance level of the controlled object, it is possible to control permission for the person holding the card to use the controlled object.
