Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a room entry control 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.

[Prior art]

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. Therefore, conventional measures have been taken to restrict entry to computer rooms by providing doors that can be opened and closed using a card inserted at the entrance of the computer room.

FIG. 1 is a diagram showing the relationship between computers, a computer room, and an entry control device, and (l) is a computer room in which a computer (2) consisting of components M1 to M4 is installed. There is. The computer room is equipped with a door (3), which is normally closed by a locking mechanism (41) 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 on the outer wall of the room (1). ) is inserted, and if the inserted card is a legitimate card, 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 R-separate medium and a required code recorded on the stripe is generally widely used.

However, this card's magnetic head hits the magnetic stripe and reads the contents relatively easily.

Cards can be tampered with.

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

[Summary of the invention]

The present invention provides a room entry control device that improves the above-mentioned problems, and will be described in detail below with reference to one drawing.

[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 (1 (hereinafter referred to as IC) built-in inside the plastic board (9), and the ICα1 is integrated into the plastic board (9).
Multiple input/output terminals α including power supply and ground provided on the - side of
9 by a conductor (not shown) passing through the inside of the plastic plate. And this lCf1
The number of valid uses is set in advance for G.

That is, the IC α1 acts as a counting element, and when a signal is applied from another device (not shown) through either of the input/output terminals αD, it produces an output corresponding to the input signal hole and calculates the number of effective uses. The output is output through either the input/output terminal αυ.However, if a specific signal is given to I (II), an output corresponding to it can be obtained.

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

As a reminder, if a person authorized to enter and exit a specific room has a card like this, then only that specific person can enter the room.

The card cannot be tampered with easily. FIG. 3 is a block diagram showing an example of the room entry control device according to the present invention.

For convenience of explanation, an example will be described in which when one pulse is applied to IC+11, three pulses are generated at a predetermined interval (frequency). FIG. 3 shows the relationship between the card reader (7) and IC1l[I.

In the figure, the card reader (7) mainly includes a first signal circuit (L3), a second signal circuit αJ, and a power supply circuit I, and the first circuit a3 outputs a predetermined pulse and Receives a predetermined pulse generated from the card's IC.Also.

The second circuit a3 has an identification function, and checks the authenticity of the card (8) and whether or not it has been used validly.
The determination is made based on the signal generated from a1.

Note that 147) is a voice synthesis output device connected to the second circuit 03, and if the IC card is correct, it outputs "Douzoohairikudasai." and outputs it as a voice via the speaker (C). to notify the person attempting to enter the room. Moreover, this voice synthesis output device outputs "I'm sorry" when the card is incorrect due to automatic mode switching.

Further, the power supply circuit I is a power supply for the card reader itself, and is also a power supply for flowing a required current to the ICα wound.

(L is a connector on the card reader side, and is provided with an input/output terminal ae corresponding to input/output terminal all on the card side.

The input/output terminal (16s) originates from lCa1 and has a circuit value of 3.
A predetermined pulse signal input to the input/output terminal f16 passes through the input/output terminal f16.
p) is generated from the circuit source, and passes the pulse signal input to I(jllll).The input/output terminal (16 ps) is for power supply, and +16E) is the input/output terminal for grounding.

These input/output terminals (16g), (16p), (16
ps).

(16El is the card side contact terminal part (10) that engages with connector a9) input/output terminal fils), (lip), (
(11Fi) and exchange signals and supply power.

That is, by engaging the contact terminal portion +lη of the card (8) with the connector αS, the ICU of the card (8) can be made to function. Nishiki is a pulse generation circuit that generates pulses of a predetermined frequency, and a field is two inversion gates 120a) (
QD is a 1-bit memory circuit cross-connected with 20b).
An output pulse is given to the memory circuit α at the other input terminal.
AND where the output of one gate (20b) of the field is given
The gate (to) is a counter composed of flip-flops Fl and F2, which is reset at the fourth input, and produces an output of 1.2.3 in decimal terms. That is, three pulses occur. It is a preset type counter in which the number of times the C#i card has been used is set in advance, and it increments or subtracts each time the gate (20b) changes from 10' to 11', and calculates the number of valid uses. Incidentally, the signals attached to Ft and Ft indicate the trigger input terminal, S indicates the set output terminal, and R indicates the reset input terminal, respectively. (c) is a decoder that receives the output of the flip-flop, that is, the binary coded decimal output, and Q4 is the output of the decoder, that is, the decimal I
ll r2j r3J is an OR gate that takes all inputs as its corresponding output, and its output is input/output terminal (lla), (16
s) to be provided to the card reader through the

In such a configuration, if the pulse generating circuit αa is a self-oscillating type pulse generating circuit (for example, IJ-running multi), an output pulse is generated when power is supplied.

Therefore, when one pulse is applied to the 1-pit memory circuit α9 and the output of the 9 inversion gate +20bl becomes %1', a pulse train is output from the AND gate Qυ. The pulses of this pulse train are counted by a counter (c), and when three pulses are output from the decoder (2), the counter is reset. On the other hand, counter C is 1-bit memory a
The contents change each time the output from 9 to 11' is output. In other words, the number of effective uses is reduced.

To explain in more detail, the output of the decoder (c) is 1° base r
Since it is output corresponding to lJ r2J r3J,
Three pulses are output according to the oscillation frequency of the pulse generating circuit 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) reads the IC of the card (8).
detects that no is working properly, thereby confirming that the card is the correct one. If the card is a fraudulent card, three output pulses will not be generated even if one input pulse is input, so that the card reader can know that a fraudulent (or defective) card has been used.

In this way, by using a card with a built-in IC, it is possible to control the locking and unlocking of the door, and it is also possible to control the door locking and unlocking.
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.

Figure 4 shows an example of the relationship between the ICαG and the card reader (7), in which synchronized pulses are generated from the pulse generator (to) of the IC and the card reader (71), and the state of synchronization is determined. Check with the matching circuit penalty of the signal circuit (to), count the pulses that are the output of the matching circuit ■ by the counting circuit with a preset function (to), and when the count value reaches the preset value, generate a pulse with the signal (to) This is to stop the output of the card (c).Checking the synchronizing pulse in this way is useful for determining whether the card (8) is correct or not, and if a predetermined pulse output is generated from the matching circuit. If not, the counting circuit will not step, 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 given to ICαO from the signal generation circuit (7) of the card reader (7), a corresponding signal is generated from ICf1α, and the card reader (71 side) The verification circuit Q checks by intuition, and if the verification result is correct, it sends a signal (To) to lCa1m to stop the output of the IC, and the signal 0 can be used as a card confirmation signal.

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 the IC (II
In response, a specific code signal (2) is generated from the IC (l [l) and is applied to the matching circuit (b).

This matching circuit (b) is given the registration code (to) recorded in the memory (to) in the card reader (71), and when (to) and (to) match, outputs an output On''Fr, which is applied to the door opening/closing control device (5) shown in FIG.

FIG. 7 shows yet another example in which the two outputs (to) of the matching circuit (b), @ are given to the lamp driver 00,
A signal corresponding to the coincidence or mismatch in the coincidence circuit (b) is generated from the driver chrysanthemum, and either the lamp (41a) (for example, green) or the lamp (41b) (for example, red) is lit.

In other words, when the code signals (to) and (to) match, the lamp (41a) is lit at the output (to), and when entering the room
On the other hand, if the code signals do not match, a lamp (41b) is turned on at the output (to) to display the entry number.

Figure 8 shows yet another example, where the condition is that the two code signal ports (to) match in the matching circuit (b).
The code signal c! generated from Cf1[l! 3r memory Q3 is recorded so that it can be known later which card holder has entered the room.

FIG. 9 shows yet another example, in which the coincidence output of the coincidence circuit is counted by the counting circuit G13 to determine how many times the person who owns the card of which code number has entered the room, and the counted value and the code The numbers are correlated with each other by a recording control circuit and recorded in the memory (6), and by looking at the contents of the memory (6), it is easy to know who has entered the computer room and how many times. I can do it.

Note that (c) is an output device typified by a display or a printer for checking the contents of the memory at any time.

Figure 10 shows yet another example, in which it is possible to record which code number card is used to record what time the user enters the room, and the time signal generated from one clock strike and the code number (to) are mutually recorded. The data is associated and recorded in the memory via the recording control circuit (441) on the condition that a coincidence signal (9) is generated.

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

Note that (c) in FIG. 10 is used in the same way as the output device in FIG. 9.

By the way, conventionally, people who can enter a specific room are identified and a predetermined entry card (often a magnetic card)1 is used.
r: It is distributed to those people and allowed to enter the room, but with this method it is possible to know that multiple specific people have entered the room, but it is not checked at all which of the 9 members entered the room and when. This is insufficient for controlling access to computer rooms and the like that handle highly important data.

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

Figure 11 shows a different configuration from that shown in Figure 1. The computer 71-ware controls all signals from the card reader (7) and sends the signal (6) to the locking mechanism.

In most of the above-mentioned examples, when the room to be 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 described above, the present invention is effective for controlling access to storage rooms for highly important materials, computer rooms that handle high-quality data or information, and even restricting the number of people who enter the room, such as research and development vehicles. be
