Abstract

PURPOSE:To save memory capacity and to increase a processing speed by a method wherein personal data, e.g., a fingerprint, a voice, is previously stored in a card itself carried by a user being a coming in and out object, and fingerprint data from a card is collated with actually detected fingerprint data. CONSTITUTION:When a user 20 presses the forefinger of a right hand against a detecting window 15a of a terminal unit 18 mounted in the vicinity of a gate 10, a radio type non-contact card 16 carried by the user 20, in which fingerprint data of the forefinger of the right band of the user is previously registered, detects transmission radio always transmitted from the terminal unit 18 by means of a receiving system. A command is made on a control part 18 so that registered fingerprint data from a memory 30 is transmitted. Actual fingerprint data of the forefinger of the right hand of the user 20 is detected by a fingerprint detecting part 15. Registered fingerprint data transmitted from a non-contact type card 16 is collated to actual fingerprint data detected by the fingerprint detecting part 15 by a collating means 52. When the two data coincide with each other, a control signal is outputted so as to open a gate 10.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is an entry/exit system that performs door unlocking, etc. by comparing personal data such as fingerprints and voice registered in advance with actually detected personal data. Regarding a management device.

[Prior art] In recent years, in buildings and facilities such as banks and companies, terminals for entry/exit control are installed at the gates of rooms where documents are stored in order to strengthen disaster prevention management. Only registered specific people are allowed to enter and exit.

Figure 4 shows a conventional entrance/exit control device.
An example is taken where the system is shared with monitoring equipment for disaster prevention, etc.

In FIG. 4, 1 is a receiver, and a terminal 8 is connected to the transmission line 9 led out from the receiver 1 to manage entry/exit, so that the opening/closing of the gate 10 can be controlled by the terminal 8. .

The receiver 1 is equipped with a display section 2, a ringing section 3, a printer 4, an input/output section 5, a control section 6 using a CPU, and an operation section 7 for disaster prevention and crime prevention monitoring, and further includes input/output using a fingerprint. Taking exit management as an example, fingerprint data of a person subject to entry/exit management is registered in advance in the memory 12 of the control unit 6.

On the other hand, the terminal device 8 includes a card reading section 14 that reads the card 13 inserted from the card insertion slot, and a fingerprint detection section 15 that detects a fingerprint by pressing a finger against the card 13.

In such a person access management device, when entering a room, the user inserts the card 13 into the terminal device 8 through the card insertion slot, and at the same time presses a specific finger on the fingerprint detection section 15.

The card reading unit 13 reads the user code etc. magnetically recorded on the card and sends it to the control unit 6 of the receiver 1, and the control unit 6 reads the fingerprint data registered in the memory 12 using the user code as a search key. and sends it back to the terminal device 8. Next, the terminal device 8 receives the registration data from the receiver 1 and the fingerprint detection unit 15.
The fingerprint data actually detected is compared with the fingerprint data actually detected, and if the two match, for example, if the distance determined by pattern matching is less than a predetermined value, the gate 10 is controlled to open.

[Problems to be Solved by the Invention] However, with such conventional entry/exit control devices, if, for example, 1,000 employees are subject to entry/exit, it is difficult to receive personal data such as fingerprints of all employees. It is necessary to store and register the registered data in the memory of the machine, that is, the host side, read and transfer the registered data in response to a terminal request, and check it on the terminal.
As the storage capacity of registered data increases, the processing load on the receiver control section increases due to receiving processing requests from a large number of terminals, and the processing time also increases.

The present invention has been made in view of these conventional problems, and eliminates the need for registering personal data on the receiver control unit, that is, the host side, and for reading and transmitting registered data based on terminal requests, thereby reducing memory capacity. The purpose of the present invention is to provide an entry/exit control device that saves money and speeds up processing.

[Means for Solving the Problems] In order to achieve this purpose, the entrance/exit control device of the present invention uses a card carried by the user that stores user-specific personal data such as fingerprints and voice, and two people. a detection unit that detects predetermined personal data such as fingerprints and voice of the user when leaving the room;
and a terminal device comprising a collation means for collating the detection data of the detection unit and the storage data stored in the card.

[Function] In the entry/exit control device of the present invention having such a configuration, personal data such as fingerprints and voice are stored in advance on the card carried by the user who is to enter/exit. For example, when a user presses a specific finger against the terminal to detect a fingerprint, the fingerprint data stored on the card the user is carrying is transferred to the terminal, and the fingerprint data from the card is actually detected. A comparison will be made with the fingerprint data obtained.

Therefore, there is no need to register personal data on the terminal device and the receiver control unit, that is, on the host side, and to read and transfer registered data based on terminal requests when entering and exiting, significantly reducing memory capacity and processing burden on the host. It is possible to obtain an optimal system configuration that has no effect on the device side even if the number of users increases.

[Example] FIG. 1 is an explanatory diagram showing one embodiment of the present invention.

In FIG. 1, reference numeral 10 denotes a gate serving as an entrance and exit, and a terminal device 18 of an entry/exit control device is installed near the outside of the gate 10. In this embodiment, the terminal device 18 is provided with an antenna 38, and is provided with an antenna 38 on the front side. Detection window 15 for fingerprint detection
A is provided.

On the other hand, the user 20 whose vehicle is to be managed by the entry/exit control device carries a contactless card 16, and in this embodiment uses a radio wave IC card.

Of course, a signal line for providing an opening/closing control signal is connected from the terminal device 18 to an opening/closing drive unit (not shown) of the gate 10.

FIG. 2 is a block diagram showing an embodiment of the contactless card 16 carried by the user 20 in the embodiment of FIG. There is.

In FIG. 2, a contactless card 16 using a radio wave IC card includes a reception system consisting of a reception antenna 22, a detection section 24, and an amplification section 26, and a transmission system consisting of a modulation section 32, an amplification section 34, and a transmission antenna 36. A control section 28 using a CPU is provided for decoding received data and controlling the transmission of signal transmission data based on the received data for these transmitting/receiving systems. 30 are provided.

In the memory 30 provided in the control unit 28 of such a non-contact card 16, personal data such as fingerprints and voice of the card holder is stored and registered in advance. For example, if we take an entry/exit control device that uses fingerprints as an example, the fingerprint of the right index finger of the user who has the contactless card 16 is displayed on the control unit 2.
8 in the memory 30 in advance. Fingerprint data can be registered in the memory 30 by converting a fingerprint image signal from an image carrier such as a COD into binary data and registering the data, and a dedicated fingerprint registration device is used.

When the control unit 28 receives a request to read the registered fingerprint data from the reception system including the reception antenna 22, the detection unit 24, and the amplification unit 26, the control unit 28 reads out the fingerprint data stored and registered in the memory 30, and controls the modulation unit 32, the amplification unit 34, and the amplification unit 26. The signal is transmitted to the outside via a transmission system consisting of a transmission antenna 36.

FIG. 3 is a block diagram showing an embodiment of the terminal device 18 adjacent to the entrance of the gate 10 in FIG. 1.

In FIG. 3, the terminal device 18 is first provided with a transmitter/receiver section consisting of an antenna 38, an input/output section 40, a detection section 42, an amplification section 44, a modulation section 46, and an amplification section 48. Also, CPU
A control unit 50 using Transmission line 9 is connected. Further, a collation means 52 is connected to the control section 50 so that a control signal can be sent to the gate 10 based on the collation result of the collation means 52.

In the steady monitoring state, the control unit 50 controls the modulation unit 46, the amplification unit 48,
A transmission system consisting of an input/output section 40 and an antenna 38 transmits weak radio waves modulated with a predetermined identification code to the outside. Therefore, when a user 20 carrying a contactless card 16 approaches the installation location of the terminal 18 as shown in FIG.
6, and in response to the radio wave reception from the terminal device 18, the registered fingerprint data is transmitted from the non-contact card 16.

Transmitted radio waves indicating fingerprint registration data transmitted from the contactless card 16 are transmitted to the antenna 38, the input/output section 40, and the detection section 4.
2. The signal is received and demodulated by the amplification section 44 and provided to the control section 50. The control unit 50 sets the registered fingerprint data decoded from the received signal in the matching means 52 as a matching reference.

Further, since the user 20 receives fingerprint data from the fingerprint detection unit 15 by pressing the right index finger against the detection window 15a in FIG. 1 provided corresponding to the fingerprint detection unit 15, the control unit 50 detects the fingerprint The fingerprint data from the unit 15 is provided to the matching means 52 as a comparison target. When the registered fingerprint data as a matching reference and the detected fingerprint data to be matched are prepared in the matching means 52, the matching process is started, and if the result of the distance obtained by pattern matching between the two is less than a predetermined threshold, both are assumed to match, and an open control signal is output to the gate 10.

On the other hand, if the verification means 52 determines that there is a discrepancy with the registered data, the open control signal is not sent to the gate 10, and at the same time, the control unit 50 disconnects the transmission line 9 from the input/output unit 54 based on the verification discrepancy. The system notifies the control unit on the host side (that is, the receiver) of the suspicious entry/exit and records the suspicious entry/exit, and if necessary, issues an alarm to prompt the security guard to conduct an inspection.

Next, the operation of the above embodiment will be explained.

As shown in FIG.
Press the index finger of the right hand against a as shown in the figure to perform fingerprint detection.

At this time, the user 20 carries a radio wave type contactless card 16 in which the fingerprint data of his right index finger is registered in advance, and the contactless card 16 is constantly connected to the terminal 18 by the receiving system shown in FIG. It detects the transmitted radio wave and instructs the control unit 28 to send registered fingerprint data from the memory 30. For this reason, the non-contact card 16 transmits the registered fingerprint data read from the built-in memory 30 to the antenna 38 of the terminal device 18 by radio waves.

As shown in FIG. 3, the terminal device 18 receives and decodes the transmitted signal from the contactless card 16 received by the antenna 38, reproduces the registered fingerprint data of the user 20 transmitted by the control section 50, and performs verification. It is set in means 52 as a reference standard.

On the other hand, the fingerprint detection unit 15 has detected the actual fingerprint data of the right index finger of the user 20, and the verification means 52 has detected the registered fingerprint data transmitted from the contactless card 16 and the fingerprint data detected by the fingerprint detection unit 15. The fingerprint information is compared with the actual fingerprint data, and if the two match, a control signal is output to open the gate 10.

In this way, the registration data necessary for entry/exit management using fingerprints is registered in the contactless card 16 carried by the user, so that the terminal device 18 is not centrally managed as in the past. There is no need to pre-register registration data such as fingerprints for a large number of users in the memory of the machine, that is, the host, and the memory capacity of the host can be significantly reduced.

In addition, in order to transmit the registered data stored in the contactless card 16 carried by the user 20 to the terminal device 18 and compare it with the actual detected fingerprint data, a read request is made to the host to read the registered data, and the data is read from the terminal. There is no need for continuous transfer of registration data on the host side in response to requests, and terminal device 1
Even if the number of 8 installed increases, the processing speed of the system as a whole is not affected at all, and at the same time there is no need to change the system configuration.

In the above embodiment, a radio wave type IC card is used as an example of the contactless card 16, but the contactless card 16 is not limited to this, and may be an optical type or magnetic coupling type IC card. It may be. In the case of the optical method or the magnetic coupling method, it is necessary to position the IC card at a predetermined position with respect to the terminal device 18. Therefore, the terminal device 18 is provided with a card setting section, and the user 20 inserts an optical signal into the cart setting section. Alternatively, a magnetic coupling type IC card may be set and a specific finger placed on the detection window 15a in the same manner.

Furthermore, in the above embodiment, the terminal device 18 constantly transmits weak radio waves, and when the contactless card 16 receives these radio waves, the registered fingerprint data is transmitted.
The registered fingerprint data may be transmitted only by operating the non-contact IC card 16 without transmitting radio waves for reading from the terminal 18.

Of course, the present invention is not limited to the entry/exit control device based on the user's fingerprint shown in the above embodiment, and it is of course possible to use the user's voice or the like according to a predetermined message as personal data. be.

[Effects of the Invention] As explained above, according to the present invention, when a user registers data such as fingerprints and voice on a contactless card carried by the user and approaches a terminal installed at the site. The registration data of the contactless card is sent to the terminal side and the actually detected fingerprints, voice, etc. are compared and judged, so the receiver that centrally manages the terminal device, that is, the host side There is no need to register and store data such as fingerprints and voices regarding a large number of users in the memory of the host, and the memory capacity on the host side can be significantly reduced.

In addition, entry/exit management can only be performed in the process between the contactless card carried by the user and the terminal, so unlike conventional methods, the host side reads the registered data in response to a read request from the terminal. There is no need for any processing to be forwarded to the side, and even if the number of installed terminals and users increases, the equipment configuration will not become complicated or the verification processing time will increase, and the input/output for a large number of users can be handled with a simple equipment configuration. Retirement management can be performed efficiently.
