Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a room entry management device for managing people entering a specific room such as a computer room.

Note that for convenience of explanation, a computer room will be used as an example. As is well known, computers not only process a large amount of data or information, but in many cases, computers also handle information related to the fundamentals of business management. In the past, 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 to the computer room.

Figure 1 is a diagram showing the relationship between computers, a computer room, and the entrance control device.
1 [Elements M1 to M4 or the computer (2) are installed. The computer room is equipped with a door (3), which is normally closed by a locking mechanism (4), and receives a signal (6) from a door opening/closing control device (5).
It can be opened by (7) is door = (3)
A card reader (7) installed near the outside wall of the room 11) is equipped with a card (not shown) (distributed to a specific person such as an operator).
If the inserted card is a legitimate one, an output (6) is generated from the door opening/closing control device (5) and the door (3) is unlocked.

By the way, in conventional devices, a plastic card provided with a magnetic stripe as an identification medium and a required code recorded on the stripe is generally widely used.

However, the contents of this card can be read relatively easily by hitting the magnetic strip with a magnetic head, and the card can be tampered with.

Furthermore, if it comes close to a magnetic material, the recorded contents will be erased and it will no longer function as an identification card.

The present invention provides a room entry control device that has improved the above-mentioned problems, and will be described in detail below with reference to the two drawings.

Figure 2 shows a card (8) that plays an important role in this invention.
), and the feature of this card is that it has an integrated circuit +ll (hereinafter referred to as Xa) inside the plastic plate (9), and its
) is connected to a plurality of input/output terminals (10) including a power source and ground provided on the negative side of the plastic plate by a conductor (not shown) running inside the plastic plate.

The number of valid uses is set in advance in this l0I11.

That is, the above IC (11) acts as a counting element.

When a signal is applied from another device (not shown) through either of the input/output terminals 0υ, an output corresponding to the input signal is generated and the number of effective uses is reduced.
It is output via either the output or the input/output terminal (11).

However, if a specific signal is given to work 001.

You can get the corresponding output.

Therefore, by specifying the type of output in response to input in each IC of each card, each card can be identified.

Therefore, if such a card is given to a person authorized to enter/exit a specific room, only the specific person can enter the room, and the card cannot be tampered with easily.

FIG. 3 is a configuration diagram showing an example of the room entry control device according to the present invention.

For convenience of explanation, when one pulse is given to l0QQ, three pulses or a predetermined interval (frequency)
This will be explained by taking as an example the case where this occurs.

FIG. 3 shows the relationship between the card reader (7) and the controller. In the figure, the card reader (7) mainly includes a first signal circuit α and a second signal circuit (13).

The first circuit Ua outputs a predetermined pulse and receives a predetermined pulse generated from the IC of the card. The second circuit a has an identification function and determines the authenticity of the card (8) and whether or not it has been used validly based on the signal generated from the iQ.

In addition, the power supply circuit (14 is the power supply for the card reader itself, as well as the power supply for flowing the required current to the IOill. +19 is the connector on the card reader side, and the input/output terminal Ql on the card side) and an input/output terminal ae corresponding to the input/output terminal ae. The input/output end (16s) is 0 (possibly II).

and a predetermined pulse signal input to the circuit (2).

The input/output terminal (16p) originates from the circuit board, and: [0(
The pulse signal input to 11 passes through. In addition, the input/output terminal (
16p11) is for power supply, and (16m) is the input/output terminal for grounding.

These input/output terminals (16g), (16p) * (
*(16") is the card side contact terminal part (input/output terminal (118) of Iη) that engages with connector u9, (1
1p), (11plI), and (11E) to exchange signals and supply power.

That is, the contact terminal portion aη of the card (8) and the connector 1
If 1!9 is engaged, the function 0tll of card (8) can be made to function. Ql is a pulse generation circuit that generates a pulse of a predetermined frequency, and ill is a two-way inverting circuit)
(20a) A 1-bit memory circuit in which (2ob) is connected in parallel, c! 0 is an AND gate where one input terminal of the two input terminals is given the output pulse of the pulse generator circuit +111, and the other input terminal is given the output of one of the memory circuit a field (+) , Q are flip-flops F1. It is a counter consisting of F2, which is reset by the fourth input pulse, and produces outputs of 15, 2, and 3 if expressed in decimal form. That is, three pulses occur. For C, the number of times the card can be used is set in advance.
It is a preset type counter.

Each time the gate (20''b) changes from "0" to "1", an addition or subtraction step is performed to reduce the number of valid uses.

Note that the T signal attached to e Fi s F2 indicates the trigger input terminal, the 2nd signal indicates the set output terminal, and R indicates the reset input terminal. (C) is a decoder whose input is the output of a flip-flop, that is, the binary coded decimal output; I
24 is the output of the decoder, i.e. decimal “1” “2”
It is an OR gate that receives the output corresponding to "3" as input, and its output is supplied to the card reader through input/output terminals (11a) and (16θ).

In such a configuration, if the pulse generating circuit +19 is a self-oscillating type pulse generating circuit (such as a free running multi-channel circuit), an output pulse is generated when power is supplied.

Therefore, if one pulse is applied to the 1-bit memory circuit Ql and the output of the 1-inverting gate (20b) is "1", A
A pulse train is output from the ND gate C1υ.

The pulses of this pulse train are counted by a counter @.

The counter is reset when three pulses are output from the decoder (c). On the other hand, the counter C changes its contents every time a "1" is output from the 1-bit memory OI. In other words, the number of effective uses is reduced.

In more detail, the output of the decoder (c) is decimal ``
This is because it is output corresponding to ``1'', ``2'', and ``3''.

Three pulses are generated in response to the pulse generating circuit α's rapid oscillation frequency and are output, and are given to the card reader (7) to indicate that the card is within the valid number of times.

Therefore, the card reader (7) can read the OQ of the card (8).
detects that the card is working properly, thereby confirming that the card is the correct one. If it is a fraudulent card, three output pulses will not be generated even if one input pulse is input, so the card reader will be able to know that a fraudulent (or defective) card has been used. By using a card with a built-in IC, it is possible to control the locking and unlocking of the door.
Since it uses C, which is not easy to tamper with, and sends and receives signals through interaction with the card reader, there are no problems like with conventional magnetic cards, and the card itself cannot be used for more than its valid number of uses. This allows for strict management of computer rooms, etc.

Next, some embodiments of this invention will be further explained.

FIG. 4 shows an example of the relationship between ICQI and the card reader (7), in which synchronized pulses are generated from the pulse generator (C) of the ICQI and the card reader (7), respectively.

The synchronization state is checked by the coincidence circuit (5) of the signal circuit (c), and the pulses that are the output of the coincidence circuit (5) are counted by the counting circuit (to) with a preset function, and the counted value becomes the preset value. When this happens, the output of the pulse generator (c) is stopped using the signal (2). Checking the synchronization pulse in this way helps in determining whether the card (8) is correct or not. If the matching circuit does not produce a predetermined pulse output, the counting circuit will not advance, and therefore the door opening/closing control device ( 5) will not result in output (6).

FIG. 5 shows another example in which a predetermined signal is applied to l0QI from the signal generating circuit (to) of the card reader (7).

A corresponding signal C33 is generated from C014 and checked by the verification circuit 611 on the card reader (7) side, and if the verification result is correct, the signal C33 is sent to the ICH to stop the output of Xa. , the signal G can be used as the card confirmation number 4g.

FIG. 6 shows yet another example in which a predetermined signal is generated from the signal generation circuit (to) of the card reader (7) and given to the circuit 04, and in response, a specific code signal is generated from the IC (11). (
) is generated and fed to the matching circuit (b).

This Maki circuit (b) is given a registration code (to) recorded in the memory (to) in the card reader (7), and C (Lv, (to) matches). In this case, output C (η) is output and applied to the door opening/closing control device (5) shown in FIG.

FIG. 1 shows yet another example in which the two outputs of the matching circuit (2) and (2) are given to a speech synthesis output device (4G), and the matching circuit from the matching circuit to An audio signal corresponding to the mismatch is generated from the speaker 0υ.

That is, when the code signal and (to) match, the output (to) is given to the speech synthesis output device +41 to generate a sound corresponding to room entry OX, and on the other hand, when the code signal does not match, the output (to) is given to the speech synthesis output device +41. is applied to the voice synthesis output device +41 to generate a voice corresponding to room entry no.

FIG. 8 shows yet another example, in which the matching circuit (product) stores the code signal (to) generated from 0111 on the condition that the two code signals (to), Of9 match, and the memory (4)
This allows you to later find out which card holder entered the room.

Figure 9 shows yet another example, in which the matching output of the matching circuit is counted by the counting circuit 03 to determine how many times the person who owns the card with which code number has entered the room, and the count value of 7 and the code number are counted by the counting circuit 03. and are linked to each other by a recording control circuit (441) and recorded in the memory +43.By looking at the contents of the memo Ij Q3, it is possible to easily know who has entered the computer room and how many times.

Note that (4) is a display for checking the contents of the memory at any time, or an output device such as a printer.

Figure 10 shows yet another example, in which a card can be used to record which code number card was used to enter the room and at what time.
The time signal and code number generated from 2 and 4 are
44 through the recording control circuit 441 on the condition that the coincidence signal c3η is generated.
It should be recorded in the following.

In this way, it is possible to easily know who entered the room and when.

Note that the output device (4S) in Figure 10 is used in the same way as the output device (4S) in Figure 9.

By the way, in the past, people who can enter a specific room are identified and a predetermined entry card (often a magnetic card) is distributed to them to allow them to enter the room. It is known that the person entered the room, but there is no check at all about which of them entered the room and when. This is not sufficient for controlling access to a computer room, etc., which handles data of varying degrees of importance.

As described above, the present invention can also deal with such conventional problems.

Fig. 11 shows a configuration different from that shown in Fig. 1. The difference from Fig. 1 is that Ml, which is one of the components of the computer (2), has the function of a door opening/closing control device. This is due to the fact that the card reader (
7), and the signal (6) can be applied to the locking mechanism.

It goes without saying that in most of the above examples, when the room to be managed is a total of stomach.

As described above, the present invention is effective for controlling access to storage rooms for highly important materials, computer rooms that handle important data or information, and even research and development rooms where the number of people entering the room is limited. be.
