Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a room entry management device for managing people entering a computer room. As is well known, computers not only process a large amount of data or information, but in companies they often handle information related to the fundamentals of business management. Therefore, measures are taken to restrict entry to computer rooms by installing doors that can be opened and closed using a card inserted into the computer room entrance by an employee.

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 understand at all.

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.

FIG. 1 is a diagram showing the relationship between a computer, a computer room, and a room entry control device, and (I) is a computer.

A computer (2) consisting of components M and -M4 is installed therein. 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). ing. (The power is a card reader located near the door (3) and on the outside wall of the room (1).

In such a configuration, a magnetic card distributed to a specific person such as a computer operator is inserted into the card reader (7), and the code number recorded in the magnetic recording section (strive) of the magnetic card is registered. If the code number matches the code number, the control device (5) generates a signal (6) and the locking mechanism (4) unlocks the door (3), allowing it to be opened. This mainly shows the door opening/closing control device that is a feature of the invention. (41, +51
．． (61, (The forces are the same as shown in Figure 1.)
8) One side has a name written on it and a photograph of the person's face pasted on it, and the other side has a magnetic stripe (magnetic part) and some notes written on it. This magnetic card is distributed only to those authorized to enter the computer room (1).

(9) is a memory in which the code number (for example, an employee number may be used) of the person authorized to enter the computer room is recorded.

α[ is a matching circuit that checks whether the code number read from the card (8) and the code number recorded in the memory (9) match or not, and if the two match, it outputs αυ. , which is applied to the locking mechanism (4) via the amplifier Q).

The locking mechanism (4) is composed of a solenoid, a locking bin moved by the solenoid, and a spring for automatically returning the bin.The solenoid moves the bin by the output of the amplifier (I2) and locks the door. Release.

Thus, the spring action causes the bin to lock the door when the solenoid is not energized. (II is a gate, which sets the output of the matching circuit (11) as an open condition and passes the code number read by the reader (7).

Note that, for convenience of explanation, a single code number will be used for explanation here, but it goes without saying that the same can be applied to a plurality of code numbers. ■ is a counting circuit, which measures the number of times each code number is read (i.e., the number of times the room is entered)
is counted, and the counting result is given to the memory αe along with the code number via the recording control circuit (I!9. Memo IJ (1
6, the code number and the number of times the room has been entered are recorded in a recording format as shown in FIG.

Figure 3 shows that the person assigned the code number ``83025j'' entered the room seven times.

If the user enters the room again next time, the number of entries will be updated to "8", and will be updated in the same manner from then on.

Therefore, by looking at the contents of memory 011, it is possible to easily know which code number a person entered the room and how many times, and how to deal with computer-related troubles (for example, falsification of data or information). can be improved.

By the way, the above-mentioned embodiment is a basic one, and there are two various modifications.When checking the contents recorded in the memory αQ, which will be further explained below, the attached output means 07) (CRT display, or printer)
If so, you can read the contents and display or print them. 0 barrel is a clock that can output a clock signal α1, and the above-mentioned signal (1g) is given to the recording control circuit 01 to detect, for example, a person entering the room from the start time to the end time.

In addition, the entry time is recorded in memory (1 [9) in chronological order for each code number.

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

FIG. 4 shows an example in which the code number and room entry time recorded in this way are printed by a journal printer used as the output means a1, and the code number is "83".
Person 025 J first entered the room at 8:15 a.m., and has been in and out several times since then. This indicates that the last time he entered the room was at 4:20 p.m. On the other hand, the person with the code number [83026J entered the room at 9:40 a.m., and the person with the code number [83026J] entered the room at 4:00 p.m.
The figure shows a further embodiment of the invention. That is, the configuration of FIG. 5 further enhances some of the configurations described using FIGS. 1 to 4.

In the configurations shown in FIGS. 1 to 4, even if an unspecified person borrows the card of a specified person B, he or she can enter the room. Therefore, if the card is dropped or stolen, important information may be leaked, which may exacerbate the problem.

Therefore, in the configuration shown in Fig. 5, in addition to inserting the card, it is also necessary to enter a specific number (PIN number) different from the code number that is memorized in the human head. It was made so that it could not be opened. (To) is a numeric keypad used for this purpose, which is operated to input the above-mentioned password.

Therefore, under certain conditions, the memory contents of the memo (January 9), the code number entered by the card, and the numeric keypad (
If the three PIN numbers entered in b) match, the output will be α
υ never occurs, so the door cannot be opened and it is not possible to enter the computer room. In this way, even if a person steals the card (8) and tries to misuse it, they will not be able to enter the room unless the specified person divulges the password.

Since this invention is configured as described above, it is extremely effective in controlling entry into a computer room.
