Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a room entry control device that completely controls entry into a specific room such as a computer room.

Note that for convenience of explanation, a computer room will be used as an example.

[Prior art]

As is well known, computers not only process a large amount of data or all information, but also often handle information related to the fundamentals of business management in companies. Therefore, measures have been taken to restrict entry to computer rooms by, for example, installing a door at the entrance to the computer room that can be opened and closed using a card.

1st rj! J is a diagram showing the relationship between computers, a computer room, and a room access control device, (1) is a computer room, in which a total of n machines (2) consisting of components M1 to M4 are installed. It is. The computer room is equipped with a door (3), which is normally closed by a lock mechanism (4) and is opened by a signal (6) from the door opening/closing control device ft (51). (71tI
A card reader (7) installed near the i-door (3) and on the outer wall of the room (1).
If the card shown in the figure (distributed to a specific person such as an operator) is inserted and the inserted card is a genuine card, an output (61 will be generated) from the door opening/closing control device (5). , unlock the door (3).

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 entire contents of this card can be read out relatively easily by hitting the magnetic stripe of the magnetic head, and the card can be completely destroyed.

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

[Summary of the invention]

This invention provides a room entry management system that has overcome these problems and will be described in detail below.

[Embodiments of the invention]

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 0α (hereinafter referred to as IC) inside the plastic plate (9).

)'(Built-in 1m, its engineering COυ is a plastic plate (9
) is connected to the plurality of input/output terminals 011 including electric and ground provided on the side by a conductor (not shown) passing through the inside of the plastic plate. Acts as.

As shown in the figure, when a signal is applied from another gear device through one of the input/output terminals Qb, an output corresponding to the input signal is generated, and that output is applied to the input/output terminal aII (all valves). This is what outputs 6.

However, if a specific signal is given to I(Nlα.

You can get the corresponding output.

Therefore, by specifying the type of output relative to the input for each XC Ic of each card, each card can be identified.

Therefore, if such a card is given to a person authorized to enter and leave a specific room, only one 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 work 001, three pulses are given at a predetermined interval (frequency).
If this occurs, explain it on the gold side.

FIG. 3 shows the relationship between the card reader (7) and the engineering CQI. In the figure, a card reader (711d) has a first signal circuit 02 and a second signal circuit 0.

A first circuit O3 outputs a predetermined pulse and receives a predetermined pulse generated from the circuit C of the card. Further, the second circuit Q31 has an identification function and determines the normality of the card (8) based on the signal generated from the circuit Ca.

Note that (4η is a voice synthesis output device connected to the second circuit α3, and if the IC card is correct,
[Douzoohairikudasai. '' and converts it into audio through the speaker 0 mark to notify the person attempting to enter the room. In addition, this voice synthesis output device automatically switches modes and outputs the message ``I'm sorry.'' if the card is incorrect. The power supply circuit α41 is the power supply for the card reader itself, and also provides the necessary power to the ICan. It is a power source for flowing the first current.

09 is a connector on the card reader side, and is provided with an input/output terminal fle'i corresponding to the input/output terminal 01) on the card side. The input/output terminal (1<58) receives a predetermined pulse signal generated from the output OQω and is input to the circuit 03, and the input/output terminal (1<58) passes through the input/output terminal (1<58).
16F) passes the pulse signal generated from the circuit O2 and input to ICan. The input/output terminal (16PS) is for power supply, and (16K) is the input/output terminal for grounding.

These input/output terminals (1 (5S), (16P),
(16PS), (1 (SF) is the input/output end (11S) of the card side contact terminal part αD that engages with the connector (151)
, (11F), (11PS), (11E)
and (13) respectively.

This is used to send and receive signals and supply power.

In other words, the contact terminal part αη of the card (8) and the connector Q
51, the ICan of the card (8) can be activated. 08 is a pulse generation circuit that generates a pulse of a predetermined frequency, a9 is two inversion gates (2OA)
(20b) 'i cross-connected 1-bit memory circuit,
Ql) is an AND gate in which one of the two input terminals is given the output pulse of the pulse generation circuit OB, and the other input terminal is given the output of one gate (20b) of the memory circuit 4. Flip-flop F1゜F2 F)
It is a counter configured from 1.0 to 1.0, which is reset by the 4th input pulse, and expressed in decimal form as 1. 2.
An output of 3 results. Ding nawachi.

Three pulses occur.

Note that the T signals attached to Fl and F2 indicate the trigger input terminal, S indicates the set output terminal, and R indicates the reset input terminal. (c) is the output 1 of the flip-flop
Q4 is a decoder that takes binary coded decimal power as input.
is the output of the decoder, i.e. decimal rIJr2Jr3J
The output corresponding to the input is an OR gate (14), and the output is the input/output terminal (11S),
(16B) The entire card is sent to the card reader.

In such a configuration, if the pulse generating circuit 0 is combined with 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 given to the 1-bit memory circuit a9 and the output of the 9 inverting gate (2ob) becomes "1", A
A pulse train is output from the ND gate Qυ. This bar
The pulses of the pulse train are counted by a counter Qz, and when three pulses are output from the decoder (c), the counter is reset.

8 and 8, it is output in response to the output FilO advance rIJr2Jr3J of the decoder (c).

Three pulses are generated according to the 0 second oscillation frequency of the pulse generating circuit and are applied to the card reader (7).

Therefore, the card reader (7) reads the card (8)
Detects that the I has operated correctly, thereby confirming that the card is the correct one. If the card is invalid (15), three output pulses will not be generated even if one input pulse is fully input, so the card reader can know that a fraudulent card has been used.

By using a card with a built-in IC, it becomes possible to control the locking and unlocking of the door.
Since it uses C, which is not easy to change, and also exchanges signals in a mutual relationship with a card reader, it does not have the problems of conventional magnetic cards.

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

FIG. 4 shows an example of the relationship between the CO1 and the card reader (7), in which synchronized pulses are generated from the pulse generator (C) of the CO1 and the card reader (7).

The synchronization status is checked by the matching circuit (5) of the all signal circuit (A), and the counting circuit (C) with pulse all presetting function, which is the output of the matching circuit (5), counts the pulse, and the counted value becomes the preset value. When this happens, the output of the pulse generator (c) is stopped using the signal -. Checking the synchronizing pulse in (16) in this way is useful for determining whether the card (8) is using the correct force or not, and if the matching circuit does not produce a predetermined pulse output, the counting circuit will not advance, and therefore the door will not open or close. There will be no output (6) from the control device (5).

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

A corresponding signal is generated from ACT 0(1(I) and checked by the verification circuit 0υ on the card reader (7) side. If the verification result is correct, the signal 03 is sent to ACT CaO and the output of ACT C is stopped. The signal 03 can be used as a card confirmation signal.

Fig. 6 shows another example in which a predetermined signal is generated from the signal generation circuit (to) of the card reader (7) and given to the IC (1 (I) to a specific signal). Generate all code signals and feed them to the matching circuit.

This matching circuit (goods) is given a registration code (to) recorded in the memory (to) in the card reader (7), and if (to) and (to) match, An output (9) is output to the door opening/closing control device (5) shown in Figure 1.

Another example is shown in FIG.
Given, the driver 〇〇 generates a signal lamp (4) corresponding to the match or mismatch in the matching circuit (goods).
1a) (for example, green) or lamp (411)) (for example, red).

In other words, when the code signal C131 and (to) match, the lamp (41a)' is lit at the output (to) to indicate OK to enter the room; on the other hand, when the code signals do not match, the output (to) ) to turn on the lamp (4ib) i and enter the roomN
O'iH table.

It was designed as shown.

FIG. 8 shows yet another example, in which the code signal C11'e generated from Ca[ is generated from the code signal C11'e (4 This allows you to later find out which card holder entered the room.

Figure 9 shows another example, in which the number of times a person who owns a card with which code number enters the room is counted by the coincidence output total counting circuit @3 of the coincidence circuit, and the counted value. and the code number are associated with each other in the recording control circuit 04) and stored in the memory (
It was designed to record information in one place, and by looking at the contents of the memory (4), it was easy to find out who entered the computer room and how many times.

It should be noted that this is an output device such as a display or a printer for checking the contents of the memory at a timely manner.

Figure 10 shows yet another example, in which it is possible to record which code number card is used and what time the user enters the room.The time signal generated from the 1-clock OQ and the code number (to) can be recorded. In addition, on the condition that a coincidence signal 0η is generated, it is recorded in the memory O2 via the recording control circuit θ.In this way, it is easy to know who entered the room and when. can.

Note that (c) in FIG. 10 is the same as the output device 0 to 9 in FIG. 9 and is fully usable.

By the way, in the past, a specific person was allowed to enter a specific room, and a predetermined entry card (often a magnetic card) was used.
I distributed the ``Fi'' to those people and entered the room 8 times, but it is true that more than one specific person entered the room using this method, but I never checked which of the 1 specific person entered the room and when. Not yet. This is insufficient for controlling access to computer rooms and the like where highly important data and other meetings are handled.

As described above, the present invention can also address these conventional problems.

Figure 11 shows a configuration different from that shown in Figure 1.The difference from Figure 1 is that Ml, one of the constituent elements of the computer (2), has the function of a door opening/closing control device. The computer hardware controls the signal from the card reader (7) and sends the signal (6) to the lock mechanism.

In most of the above examples, when the room being managed is a computer room, it goes without saying that the functions of the computers located in that room can be used as if they were part of the room entry control device. .

〔Effect of the invention〕

As mentioned above, according to the present invention, storage rooms for highly important (20) materials, computer rooms that handle important data or information, research and development rooms where entry is restricted to pregnant women, etc. Effective for room entry control.
