Description

  The present invention relates to a reader and an entrance / exit management system.

  Conventionally, in order to suppress the occurrence of incomplete processing when a user enters or enters, a user who is going to pass through the ticket gate is photographed with a camera, and the captured image is used. There is known a gate device that detects a user's line-of-sight direction and performs notification that prompts the user to hold the non-contact IC card over the antenna when the user's line-of-sight direction is other than the antenna direction (for example, Patent Document 1). reference).

  Moreover, in the conventional entrance / exit management system, what is provided with the reader which reads the identification information described in the ID tag with the radio signal is known. In this conventional entrance / exit management system, the identification information of the ID tag possessed by the user is read only by the user entering the tag detection range of the reader. For this reason, authentication can be performed without requiring a predetermined operation (holding a non-contact IC card over an antenna) unlike the conventional gate device described in Patent Document 1.

  However, in such a conventional entrance / exit management system using a so-called hands-free tag, the ID tag identification information can be read only by the user having the ID tag entering the tag detection range of the reader, and Then, authentication based on the read identification information and door unlocking are performed. For this reason, there is a possibility that the door is unlocked because an ID tag possessed by a user who does not intend to pass through the door enters the tag detection range.

  In addition, in the gate device described in Patent Document 1, it is rare that authentication of a user who does not intend to pass is performed, but in order to perform authentication, a predetermined contact of holding a non-contact IC card over an antenna is performed. The user needs to perform the operation.

  The present invention has been made to solve such a problem, and is capable of reading identification information without requiring a special operation by a user and using the information without intention to receive authentication. That can prevent the identification information of the ID tag possessed by the person from being read and can read the identification information of the ID tag possessed by the user who intends to be authenticated, and an entrance / exit management system provided with the same Is what you get.

In reading apparatus according to the present invention is a read reader pre SL identification information of the information storage medium that transmits identification information upon receiving the first radio signal itself stored in the second radio signal, reader and more based on the captured image, the direction of the user's line of sight is detected that is directed to the inside of the target range to a predetermined line-of-sight detecting unit to the imaging unit for photographing the user approaching the, When the line-of-sight detection unit detects that the direction of the user's line of sight is directed to the inside of a target range, the line-of-sight detection unit transmits the first wireless signal and is transmitted from the information storage medium. And a receiving unit that receives the second radio signal and a control unit that acquires the identification information from the second radio signal received by the receiving unit.

  In the entrance / exit management system according to the present invention, authentication is performed by comparing the reading device as described above, the identification information acquired by the control unit of the reading device, and authentication information stored in advance. An authentication device is provided, and an electric lock that locks and unlocks the door based on the authentication result of the authentication device.

  In the reading apparatus according to the present invention and the entrance / exit management system equipped with the same, the identification information can be read without requiring any special operation by the user, and the use is not intended to be authenticated. It is possible to prevent the identification information of the ID tag possessed by the user from being read and to read the identification information of the ID tag possessed by the user who intends to be authenticated.

It is a block diagram which shows the structure of the tag reader which concerns on Embodiment 1 of this invention. It is a flowchart which shows operation | movement of the tag reader which concerns on Embodiment 1 of this invention. It is a front view of the tag reader which concerns on Embodiment 1 of this invention.

  The present invention will be described with reference to the accompanying drawings. Throughout the drawings, the same reference numerals indicate the same or corresponding parts, and redundant description thereof will be simplified or omitted as appropriate.

Embodiment 1 FIG.
FIGS. 1 to 4 relate to Embodiment 1 of the present invention. FIG. 1 schematically illustrates the overall configuration of an entrance / exit management system including a tag reader, and FIG. 2 illustrates the configuration of the tag reader. FIG. 3 is a flowchart showing the operation of the tag reader, and FIG. 4 is a front view of the tag reader.

  In FIG. 1, a living room 1 is a section partitioned inside a facility or a building. This room 1 is subject to entry / exit restrictions. An entrance / exit 1 a for entering and exiting the living room 1 from the passage 2 is provided at a location facing the passage 2 in the living room 1. A door 3 is provided at the entrance / exit 1a of the living room 1 so as to be freely opened and closed. The door 3 is locked and unlocked by the electric lock 4.

  A user who enters and exits the living room 1 has an ID tag (not shown). This ID tag is a so-called semi-active RFID (Radio Frequency IDentification) tag. Identification information that can uniquely identify each of a plurality of users is stored in advance in the ID tag. The ID tag is an example of an information storage medium that is held by a user, stores identification information, and reads the identification information by wireless communication.

  A tag reader 5 is installed in the vicinity of the entrance / exit 1a (door 3) on the wall surface of the living room 1 on the passage 2 side. The tag reader 5 is for reading the identification information stored in the ID tag by wireless communication. Here, the configuration of the tag reader 5 will be described with reference to FIG. 2 in addition to FIG. The tag reader 5 includes an LF radio wave transmission unit 51 and an RF radio wave reception unit 52.

  The LF radio wave transmission unit 51 transmits LF radio waves. LF is an abbreviation for Low Frequency, and the LF radio wave transmitted from the LF radio wave transmission unit 51 belongs to the long wave band. The RF radio wave receiving unit 52 receives the RF radio wave. RF is an abbreviation for Radio Frequency and means radio frequency or high frequency. That is, specifically, the RF radio wave received by the RF radio wave receiving unit 52 belongs to, for example, a UHF (Ultra High Frequency) band.

  The ID tag is normally in a sleep state, and stops transmitting radio signals. When the ID tag receives the LF radio wave transmitted from the LF radio wave transmission unit 51, the ID tag transmits a radio signal including identification information stored in the ID tag itself. The radio signal transmitted from the ID tag uses an electromagnetic wave in a band that can be received by the RF radio wave receiving unit 52, that is, the above-described RF radio wave. The ID tag includes a battery that supplies power for transmitting a radio signal from the ID tag.

  The tag reader 5 can read the identification information stored in the ID tag by wireless communication by receiving the RF signal transmitted from the ID tag by the RF radio wave receiving unit 52. A range in which the identification information of the ID tag can be read by wireless communication by the tag reader 5 is a tag detection range 6 shown in FIG.

  The tag detection range 6 is a range in which the ID tag can receive the LF radio wave transmitted from the LF radio wave transmission unit 51 and the RF radio wave reception unit 52 can receive the RF radio wave transmitted from the ID tag. In other words.

  When an LF radio wave is transmitted from the LF radio wave transmission unit 51 of the tag reader 5 while the ID tag carried by the user is inside the tag detection range 6, the ID tag receives this LF radio wave. The ID tag that has received the LF radio wave is activated from the sleep state. The activated ID tag transmits the identification information stored in the ID tag itself on the RF radio wave. Then, the RF radio wave receiving unit 52 of the tag reader 5 receives the RF radio wave transmitted from the ID tag.

  As shown in FIG. 2, the tag reader 5 further includes a control unit 53 in addition to the LF radio wave transmission unit 51 and the RF radio wave reception unit 52. The RF radio wave received by the RF radio wave receiving unit 52 is processed by the control unit 53. And the control part 53 acquires the identification information contained in the said RF electromagnetic wave by this process.

  ID tag identification information acquired by the control unit 53 of the tag reader 5 is sent to the ID controller 7 shown in FIG. In the authentication information storage unit 71 provided in the ID controller 7, identification information of a user who is permitted to unlock the door 3 and pass through the door 3 is stored in advance as authentication information. The ID controller 7 collates the identification information sent from the tag reader 5 with the authentication information stored in the authentication information storage unit 71, so that the user of the identification information is permitted to pass through the door 3. Authentication is performed.

  As a result of the authentication, if the verification of the identification information and the authentication information is successful, the authentication is successful. If the authentication is successful, the ID controller 7 outputs an unlock signal to the electric lock 4. Upon receiving this unlock signal, the electric lock 4 is unlocked and the door 3 can be opened. Thus, a user possessing an ID tag of identification information that has been successfully authenticated can open the door 3, pass through the entrance / exit 1 a, and enter the living room 1.

  On the other hand, when the verification between the identification information and the authentication information fails, the authentication fails. If the authentication fails, the unlock signal is not output from the ID controller 7 to the electric lock 4. Therefore, the door 3 cannot be opened, and the user's entrance / exit 1a is blocked.

  In this way, in the state where the ID tag exists inside the tag detection range 6, the ID tag identification information is read and the read identification is triggered by the transmission of the LF radio wave from the LF radio wave transmission unit 51 of the tag reader 5. Information-based authentication is performed.

  Transmission of the LF radio wave from the LF radio wave transmission unit 51 of the tag reader 5 is performed when a predetermined condition is established under the control of the control unit 53. Next, control for transmitting LF radio waves from the LF radio wave transmission unit 51 will be described.

  As shown in FIG. 2, the tag reader 5 further includes a camera unit 54 and a line-of-sight detection unit 55. The camera unit 54 is provided in front of the tag reader 5 (see also FIG. 4). The camera unit 54 photographs the situation on the passage 2 side from the tag reader 5. A camera shooting range 8 which is a range shot by the camera unit 54 extends to the front side of the tag reader 5 as shown in FIG. The camera shooting range 8 is arranged so as to at least partially overlap the tag detection range 6. At this time, it is preferable that the area of the overlapping portion between the camera photographing range 8 and the tag detection range 6 be as large as possible.

  The camera unit 54 photographs a user who is within the camera photographing range 8. The users who are within the camera photographing range 8 include users who approach from the passage 2 to the door 3. The line-of-sight detection unit 55 analyzes the image photographed by the camera unit 54 and detects the direction of the user's line of sight within the camera photographing range 8. Then, it is determined whether or not the detected user's line of sight is directed within a predetermined target range.

  This target range is determined in the target object and its surroundings where it is necessary for the user to turn his / her line of sight in order to open the door 3, or it is natural to turn his / her line of sight. Specifically, for example, the target range is set to a certain range including the knob of the door 3. Other examples of the target range include a certain range including the tag reader 5, a certain range including the camera unit 54, and a certain range including the guide plate of the door 3.

  The detection of the direction of the user's line of sight in the line-of-sight detection unit 55 is performed by first extracting the user's face from the image taken by the camera unit 54 and detecting the orientation of the extracted face. Therefore, it is preferable to arrange the camera unit 54 at the height position of the average face (head) of the user so that the user's face can be captured more clearly.

  In addition, the detection of the direction of the user's line of sight in the line-of-sight detection unit 55 can be more accurately and reliably performed when the user's eyes are included in the image captured by the camera unit 54. From such a viewpoint, it is more desirable to arrange the camera unit 54 at a position where the user's eyes can be captured more clearly.

  As described above, when the camera unit 54 is installed in front of the tag reader 5, that is, when a camera-integrated tag reader is used, the preferred installation position of the camera unit 54 is that of the tag reader 5. Position.

  On the other hand, the camera unit 54 can be provided separately from the tag reader 5. In this case, the installation position of the camera unit 54 and the installation position of the tag reader 5 do not necessarily have to be the same location. That is, the tag reader 5 and the camera unit 54 can be arranged apart from each other.

  The camera shooting range 8 of the camera unit 54 can be fixed, but the camera shooting range 8 can be changed by providing the camera unit 54 with a tilt function and / or a pan function. Good. When the camera shooting range 8 is made variable, the target range when the line-of-sight detection unit 55 determines the direction of the line of sight can be changed according to the camera shooting range 8.

  Specifically, for example, by making the camera shooting range 8 variable, the target range can be set to two types, the vicinity of the knob portion of the door 3 and the vicinity of the guide plate portion of the door 3. Then, the line-of-sight detection unit 55 determines that the direction of the user's line of sight is within the target range if the direction of the line of sight of the user is within one of these two types of target ranges. To do.

  Based on the determination result of the user's line-of-sight direction performed in the line-of-sight detection unit 55 as described above, the control unit 53 controls the transmission of the LF radio wave from the LF radio wave transmission unit 51. First, the control unit 53 normally stops the transmission of the LF radio wave from the LF radio wave transmission unit 51.

  The control unit 53 determines that the LF is detected when the gaze detection unit 55 continuously detects that the user's gaze direction is within the target range for a gaze detection holding time that is a predetermined time. The transmission of the LF radio wave from the radio wave transmission unit 51 is started. The line-of-sight detection holding time is specifically set to about 2 seconds, for example. The value of the line-of-sight detection holding time may be appropriately changed by setting.

  In addition, after starting transmission of the LF radio wave from the LF radio wave transmission unit 51, the control unit 53 determines in advance after the gaze detection unit 55 no longer detects that the user's gaze direction is within the target range. The transmission of the LF radio wave from the LF radio wave transmission unit 51 is stopped after the tag detection holding time which is the given time has elapsed.

  In other words, after the control unit 53 starts transmission of the LF radio wave from the LF radio wave transmission unit 51, while the gaze detection unit 55 detects that the user's gaze direction is within the target range, The time for continuing the transmission of the LF radio wave from the LF radio wave transmission unit 51 is extended. The tag detection holding time is specifically set to about 5 seconds, for example. The tag detection holding time may be appropriately changed depending on the setting.

The flow of LF radio wave transmission control processing from the LF radio wave transmission unit 51 in the tag reader 5 will be described once again with reference to FIG.
First, in normal time, transmission of LF radio waves from the LF radio wave transmission unit 51 is stopped (step S1). In step S2, when the line-of-sight detection unit 55 detects that the line-of-sight direction of the user who has entered the camera shooting range 8 is within the target range, the process proceeds to step S3.

  In step S3, the control unit 53 starts measuring time with the first timer. The first timer is for measuring the lapse of the eye gaze detection holding time. After step S3, the process proceeds to step S4. In step S <b> 4, the control unit 53 confirms whether or not the gaze detection unit 55 has detected that the user's gaze direction is within the target range.

  If it is not detected that the user's line-of-sight direction is within the target range, in other words, if it is detected that the user's line-of-sight direction is not within the target range, the process proceeds to step S5. In step S5, since the state in which the user's line-of-sight direction is within the target range is not continued, the control unit 53 stops timing by the first timer. Note that once the time measurement by the first timer is stopped, the time measurement state by the first timer is reset to the initial state. After step S5, the process returns to step S2.

  On the other hand, if it is detected in step S4 that the user's line-of-sight direction is within the target range, the process proceeds to step S6. In step S <b> 6, the control unit 53 confirms whether or not the first timer has timed out, that is, whether or not the measurement of the line-of-sight detection holding time by the first timer has been completed.

  When the sight line detection holding time has elapsed by the first timer, the process proceeds to step S7. On the other hand, if the elapsed time counted by the first timer has not yet reached the line-of-sight detection holding time, the process returns to step S4. When the first timer times out, the time measurement by the first timer is stopped, and the time measurement state is also reset to the initial state.

  In step S <b> 7, the control unit 53 starts transmission of LF radio waves from the LF radio wave transmission unit 51. When the transmission of the LF radio wave is started, the ID tag in the sleep state in the tag detection range 6 is activated and transmits the identification information by the RF radio wave.

  After step S7, the process proceeds to step S8. In step S8, the control unit 53 starts measuring time by the second timer. This second timer is for measuring the elapse of the tag detection holding time. After step S8, the process proceeds to step S9. In step S <b> 9, the control unit 53 confirms whether or not the gaze detection unit 55 has detected that the user's gaze direction is within the target range.

  When it is detected that the user's line-of-sight direction is within the target range, the process proceeds to step S10. In step S10, the control unit 53 resets the timing state by the second timer to the initial state. That is, the timekeeping state by the second timer is returned to the state in which timekeeping was started in step S8. After step S10, the process proceeds to step S11.

  On the other hand, if it is not detected in step S9 that the user's line-of-sight direction is within the target range, in other words, if it is detected that the user's line-of-sight direction is not within the target range, step S10 is performed. It progresses to step S11, without passing.

  In step S11, the control unit 53 confirms whether or not the second timer has timed out, that is, whether or not the tag detection holding time by the second timer has been counted. If the tag detection holding time has elapsed by the second timer, the process returns to step S1. On the other hand, if the elapsed time measured by the second timer has not yet reached the line-of-sight detection holding time, the process returns to step S9. When the second timer times out, the timing by the second timer is stopped, and the timing state is also reset to the initial state.

  If the process proceeds from step S10 to step S11, the second timer is reset in step S10. Therefore, in step S11, it is determined that the second timer has not timed out, and the process proceeds to step S9. Will return.

  In the above flow, the LF radio wave is transmitted from the LF radio wave transmission unit 51 from the time when transmission is started in step S7 until the process returns to step S1 and transmission is stopped. During this period, the ID tag within the tag detection range 6 receives the LF radio wave and transmits the RF radio wave. That is, the period from the execution of step S7 to the execution of step S1 is a period for detecting the ID tag.

  As shown in FIG. 2, the tag reader 5 further includes a display unit 56. The display unit 56 is for informing the user of the operating state of the tag reader 5 and the like. Specifically, as shown in FIG. 4, an authentication success display lamp 56a, an authentication failure display lamp 56b, and a line-of-sight detection display lamp 56c are provided on the front portion of the tag reader 5.

  When the ID controller 7 succeeds in collating the identification information with the authentication information and the authentication is successful, a signal indicating that the authentication is successful is transmitted from the ID controller 7 to the tag reader 5. When the control unit 53 receives a signal indicating that the authentication is successful, the control unit 53 turns on the authentication success display lamp 56a of the display unit 56.

  When the ID controller 7 fails to collate the identification information with the authentication information and the authentication fails, a signal indicating that the authentication has failed is transmitted from the ID controller 7 to the tag reader 5. Upon receiving a signal indicating that the authentication has failed, the control unit 53 turns on the authentication failure display lamp 56b of the display unit 56.

  When the line-of-sight detection unit 55 detects that the line-of-sight direction of the user within the camera shooting range 8 is within the target range, the control unit 53 displays the line-of-sight detection display lamp 56c of the display unit 56. Light up.

  In this way, either the authentication success display lamp 56a or the authentication failure display lamp 56b is turned on depending on whether or not the authentication is successful, and the line-of-sight detection unit 55 detects the line-of-sight direction of the user. By turning on the line-of-sight detection display lamp 56c, the user can know the authentication state and the line-of-sight detection state by confirming the lighting state of these lamps.

  In addition, as the display part 56, you may comprise using a liquid crystal display etc. other than what is comprised by the lamp | ramp (LED) mentioned above as an example. Further, instead of the display unit 56 or in combination with the display unit 56, a speaker for informing by voice is provided, and a buzzer sound or a voice message is emitted from the speaker, thereby using the authentication state and / or the gaze detection state. It is also possible to notify the person.

  Here, after the transmission of the LF radio wave from the LF radio wave transmission unit 51 is started, the gaze detection unit 55 further determines that the state in which the user's gaze direction is within the target range is not detected. The example in which the transmission of the LF radio wave from the LF radio wave transmission unit 51 is stopped after the given tag detection holding time has elapsed has been described.

  However, the control unit 53 stops the transmission of the LF radio wave from the LF radio wave transmission unit 51 after the tag detection holding time has elapsed after starting the transmission of the LF radio wave from the LF radio wave transmission unit 51. Also good. That is, after the transmission of the LF radio wave from the LF radio wave transmission unit 51 is started, the gaze detection unit 55 may measure the tag detection holding time regardless of the detection state of the user's gaze direction.

  Moreover, about the above, it demonstrated about the authentication at the time of entering the living room 1. FIG. On the other hand, the transmission of LF radio waves from the tag reader 5 can be controlled in the same manner for authentication when leaving the room 1 when the tag reader 5 is provided inside the room 1. .

  The tag reader 5, which is a reading device configured as described above, receives an LF radio wave that is a first radio signal and transmits identification information stored therein by an RF radio wave that is a second radio signal. The identification information stored in (ID tag) is read.

  The reader (tag reader 5) has a camera unit 54 that captures an image of a user approaching the reader and an image captured by the image capturing unit. When it is detected that the direction of the user's line of sight is directed to the inside of the target range by the line-of-sight detection unit 55 that detects that the line of sight is directed to the inside of the target range, An LF radio wave transmission unit 51 that is a transmission unit that transmits a first radio signal (LF radio wave), and an RF radio wave reception unit that is a reception unit that receives a second radio signal (RF radio wave) transmitted from an information storage medium 52 and a control unit 53 that acquires identification information from the second radio signal received by the receiving unit.

  For this reason, it is possible to prevent the identification information of the ID tag possessed by the user who does not intend to be authenticated from being read, and to read the identification information of the ID tag possessed by the user who intends to be authenticated.

  Furthermore, by preventing unnecessary reading of ID tag identification information held by a user who does not intend to be authenticated, unnecessary transmission of LF radio waves from the tag reader 5 is suppressed, and from the ID tag Transmission of unnecessary RF radio waves can be suppressed. For this reason, power saving and long life of the battery built in the ID tag can be expected.

  In addition, the LF radio wave transmission unit 51 has a state in which the gaze detection unit 55 detects that the user's gaze direction is directed to the inside of the target range for a predetermined gaze detection holding time or longer. First, a first radio signal (LF radio wave) is transmitted.

  Therefore, even a user who does not intend to receive authentication can be prevented from transmitting an LF radio wave if his / her line of sight is unintentionally within a target range for a very short time. . For this reason, the identification information of the ID tag possessed by the user who intends to receive authentication can be read more reliably.

  Further, after transmitting the first radio signal (LF radio wave), the LF radio wave transmission unit 51 stops the transmission of the first radio signal after elapse of at least a predetermined tag detection holding time. For this reason, it is possible to secure a sufficient time to receive the RF radio wave transmitted from the ID tag that has received the LF radio wave and acquire the identification information from the received RF radio wave. Can be suppressed.

  Further, after the LF radio wave transmission unit 51 transmits the first radio signal (LF radio wave), the gaze detection unit 55 can no longer detect that the user's gaze direction is directed to the inside of the target range. While the tag detection holding time has passed, the transmission of the first wireless signal is stopped, so that it is detected that the user's line of sight is directed to the inside of the target range. Can extend the transmission of the LF radio wave, and can secure a sufficient time to acquire the identification information more reliably.

  Furthermore, the entrance / exit management system described above includes the tag reader 5 that is the reader configured as described above, identification information acquired by the control unit 53 of the reader, and authentication information stored in advance. An ID controller 7 that is an authentication device that performs authentication by collation, and an electric lock 4 that locks and unlocks the door based on the authentication result of the authentication device.

  For this reason, it is prevented that the identification information of the ID tag possessed by the user who does not intend to pass through the door is read, and the identification information of the ID tag possessed by the user who intends to pass through the door after receiving authentication Can be read. In addition, by selecting users with intention to pass and performing ID tag authentication and door unlocking only when the user exists, unintentional door unlocking is suppressed and security is improved. Can do.

  The present invention relates to a reader for reading identification information of an information storage medium such as an ID tag that transmits identification information stored by itself when the first wireless signal is received, and such a reader. It can be used for an entrance / exit management system with
