Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an entry management device for managing people entering a computer room.

[Prior art]

As is well known, computers not only process a large amount of data or all information, but in many cases they also handle information related to the fundamentals of business management in companies.

Therefore, from now on, measures have been taken to restrict entry to computer rooms by installing doors that can be opened and closed using a card inserted at the entrance of the computer room, to restrict entry to only specific people.

However, with this method, it is possible to know which of the specified persons entered the room, but it is also possible to know which of the specified persons entered the room, and for example, who entered the room and how many times on a given day. I don't know (I don't know.

[Summary of the invention]

The present invention has been made in order to improve the problems of conventional room entry management. The present invention will be described in detail below with reference to some embodiments.

[Embodiments of the invention]

FIG. 1 is a diagram showing the relationship between computers, a computer room, and a room access control device. (1) is a computer room in which computers (2) consisting of components M1 to M4 are installed. There is. The computer room is equipped with a door (3), which is normally closed by a locking mechanism (4) and opened by a signal (6) from a door opening/closing control device (5). (7) is a card reader installed near the door (3) and outside the room (1), and this reader has a PIN number known only to the cardholder. All PIN input keys (not shown in FIG. 1) are provided.

Further, C is a camera that becomes ready to take pictures based on the signal when the door is unlocked, and takes pictures at all entrances of people who open the door and enter the room.

Note that the PIN number is a key condition for entering the room, similar to an IC card, and the door will not open even if only the card is inserted without keying in the entire PIN number.

In such a configuration, the IC built-in card distributed to a specific person such as a computer operator is inserted into the card reader (7), the PIN is keyed in, and signals are exchanged between the two parties. If the code number output from the IC built in the door matches the pre-registered code number, a signal (6) is generated from the control device (5), and the locking mechanism (4) locks the door. 3) can be unlocked and opened. The person entering the room is then photographed at the entrance by camera C.

Figure 2 shows the feature of this invention: a door opening/closing control device that makes a sound. (41, +51, (61
is the same as shown in FIG. (The power is a PIN input key (to)? A card reader equipped with (8) is a feature of this invention without sound. An IC chip S is built in the plastic board, and predetermined information (code number) is stored in the IC chip. This is a card that records information and outputs the recorded information by giving a predetermined signal from the outside.This card is distributed only to those who are permitted to enter the computer room (1). (9) is a memory in which the code number of the person authorized to enter the computer room (for example, the employee number may be used) and the PIN number, and α1 is the memory card (
The code number read from 8), the code number recorded in the memo IJ-+91, and the PIN number (To)
Does the PIN you entered match the PIN you memorized in Memo IJ-(9)? There is a matching circuit to check.

If the manually generated one and the one stored in the memory match, the full output αυ is sent to the locking mechanism (4) via the amplifier (17Jt). Qυ is a voice synthesis output device, and the output aO If this occurs, it will output "Douzoohairikudasai." and convert it into audio through all speakers C2■? to notify the person attempting to enter the room.
The above speech synthesis output device Qυ has automatic mode switching.
When the output αυ is not generated, that is, when the card (8) is defective and does not match the contents of the memory (9), it outputs "New information is required". On the other hand, the above output (
+11 is also given to camera C, making it ready for photography.

The locking mechanism (4) is composed of a solenoid, a locking pin moved by the solenoid, and a spring for automatic pin return, and the output of the amplifier 2 causes the solenoid to move the pin and completely unlock the door.

Thus, when the solenoid is not energized, the spring action causes the pin to function to lock the door. αJ is a gate, which sets the output αυ of the coincidence circuit U as an open condition, and allows all code numbers read by the reader (7) to pass through.

Note that, for convenience of explanation, the explanation will be based on one code number, but it goes without saying that the same can be applied to a plurality of code numbers.

(141 is a counting circuit, which counts the total number of times each code number is read (i.e., the number of times the room is entered), and records the counting result via a recording control circuit (lSt-) together with the image of the person entering the room (down payment photograph) and the code number, and a video recording means. αe (for example, a video disk or a video tape).The video recording means αe records images, code numbers, and the number of times the room has been entered in a recording format as shown in FIG.

FIG. 3 shows that the person assigned the code number [a 3025J k has entered the room seven times, and if he/she enters the room again the first time, the number of entries will be updated to "8", and the number will be updated in the same manner thereafter.

Therefore, what is the recorded content of the video recording means ue? You can immediately see who has entered the room and how many times.

It is possible to completely improve the way to deal with troubles related to computers (for example, falsification of data or information).

By the way, the above-mentioned embodiment is a basic one, and there are nine various modifications, which will be further explained below.

If it is desired to check all the contents recorded on the video recording means σe, if there is an attached output means α7) (CRT display), it is possible to read out all the contents and display them all. +18 is a clock that can output the clock signal αI, and the above signal αI is sent to the recording control circuit α9. For example, the number of people entering the room from the start time to the end time and the time of entry are recorded in the recording means αG in association with the code number.

In this way, it is possible to know who entered the computer room and when, for example, from the start of work at 8 a.m. to the end of work at 5 p.m.

As mentioned above, does this invention involve IC cards and PIN numbers? It is extremely effective for controlling entry into computer rooms.
