Description

  The present invention relates to a gate device installed at the entrance of a building or factory, a doorway to a specific room in a building, or a check gate of a station or an airport, and in particular, a user who has been authenticated while preventing sharing. It is related with the gate device for letting only one person pass.

As a gate device for passing only authenticated users one by one, for example, two flaps on the entrance side and the exit side that rotate in the direction of the passage with the same rotation axis center and open and close the passage are arranged along the passage. Sensors that detect the passage of users are provided near the entrance and the exit, respectively, and authentication means are provided in the middle of the passage. Normally, the exit-side flap is in a closed position substantially perpendicular to the passage. Is in an open position that is substantially parallel to the passageway, and the two flaps are substantially L-shaped to allow the user to enter and wait for the user to enter the gate device. When the sensor on the entrance side detects and the authentication means authenticates that the user is permitted to pass, the exit side is subject to the condition that the sensor on the entrance side has not detected the next user. The flap is open The flap on the entrance side closes while maintaining the substantially L-shape following it, and one person is between the flaps until the flap on the entrance side reaches the closed position where the next user can be prevented from entering. What has been known to maintain the space of minutes,

  However, the conventional gate device has a fixed space that is divided by flaps so that each user can pass one by one, so if the user has a large body shape or has luggage, it is cramped. If the user is a child or an adult who has a small body shape, there is a risk that two or more people may be allowed to enter at once. Simultaneous entry of two or more people can usually be detected by a passage detection sensor on the entrance side, but if two people approach and pass, the sensor may be mistakenly detected as one person, preventing sharing. It is impossible to pass through the gate device one by one reliably.

The present invention forms a partition space that can be adjusted according to the outer shape of the user's body shape and the like in the passage of the gate device so that only authorized users can pass one by one, and is necessary and sufficient for each user. The purpose is to ensure that two or more people are not allowed to carry out simultaneous traffic.
An illegal act of passing another person other than the authenticated person may be referred to as “replacement”, but the term “spoofing” is used in this specification.
In addition, an illegal act that a non-authenticated person follows and follows an authenticated person may be referred to as “take-in” or “co-accompaniment”. In this specification, the term “co-accompaniment” is used.

  The gate device according to the present invention is a gate device that authenticates that the user is permitted to pass and allows the authenticated user to pass through, and acquires information regarding the outline of the user permitted to pass. The outer shape information acquisition means and at least the front side and the rear side in the passage direction of a user who is passing the passage in the gate device from the entrance side to the exit side are regulated to form a partition space in the passage. It is characterized by comprising regulation means for adjusting the shape of the partition space on the basis of the external shape information of each user acquired by the information acquisition means.

It may be information about the outer shape that is combined.

  In this gate device, the regulating means regulates at least the front side and the rear side in the passage direction of a user who is passing the passage in the gate device from the entrance side to the exit side, thereby forming a partition space. It is possible to allow only the selected users to pass one by one. In particular, the shape of the partition space can be adjusted based on the external information of each user, so that necessary and sufficient partition space can be secured according to the external shape of the user's body shape, etc. Without making you feel cramped, you can prevent two or more people from entering at the same time to prevent companionship.

  Here, the restricting means may be capable of adjusting the width in the left-right direction orthogonal to the passing direction of the partition space, and adjusting the shape of the partition space by adjusting the width in the left-right direction. . In this way, by making the width in the left-right direction adjustable, the width in the left-right direction of the partition space can be adjusted according to the shoulder width of the user and the width in the left-right direction including the luggage. You can be sure to prevent side-by-side companions without feeling cramped.

  Further, the restricting means may be configured such that the width in the front-rear direction along the passage direction of the partition space can be adjusted, and the shape of the partition space can be adjusted by adjusting the width in the front-rear direction. In this way, by making the width in the front-rear direction adjustable, the width in the front-rear direction of the compartment space can be adjusted according to the chest thickness of the user and the width in the front-rear direction including the luggage. Without making you feel cramped, you can reliably prevent side-by-side companions.

  Further, the restricting means may be configured to allow the partition space to move in the row direction while substantially maintaining the shape of the partition space formed based on the external shape information of each user. In this way, by allowing the partition space to move while substantially maintaining the shape, the user can be smoothly guided to the exit side.

  The restricting means includes three or more open / close members that slide in a direction crossing the passage to open and close the passage, and the opening of the open / close members is adjusted to change the shape of the partition space. It may be changeable. In this way, three or more open / close members that slide in the direction crossing the passage to open and close the passage are arranged side by side in the passage direction, and the opening degree of the open / close members is adjusted, so that the space of the partition space The shape can be changed.

  Further, the regulating means includes four or more opening / closing members arranged in parallel in the passage direction by sliding in the direction crossing the passage, and the opening degree of the opening / closing member disposed in the middle portion in the passage direction is set. It may be possible to change the shape of the partition space by adjusting. In this way, four or more open / close members that slide in the direction crossing the passage to open and close the passage are juxtaposed in the passage direction, and by adjusting the opening degree of the open / close member disposed in the middle portion of the passage direction, It is possible to change the shape of the partition space in the front-rear direction in addition to the left-right direction.

  The regulating means, which is formed by juxtaposing four or more open / close members that open and close the passage by sliding in the direction crossing the passage, opens and closes the partition space by sequentially opening and closing the open and close members arranged in the passage. It can be movable in the direction of traffic. In this way, the user can be smoothly guided to the exit side by opening and closing each opening and closing member in order and allowing the partition space to move in the direction of travel.

  In the gate device 1, the human sensor 14 a detects a user standing in front of the entrance authentication unit 8 in step S 1 of the control procedure shown in FIG. 12, and the user's palm is placed on the camera 12. Until the sensor 14b determines that this is detected, the standby state shown in FIG.

  When it is determined in step S1 that the human sensor 14a and the sensor 14b of the entrance authentication unit 8 have detected the approach of the user and the placement of the palm, the entrance authentication unit 8 uses the palm print of the user in step S2. And the face data are obtained and collated with the pre-registered data to determine whether or not the authentication is OK (the user is a registered person). In the case of authentication OK, the user's external information stored in advance corresponding to the information for authenticating the user is transmitted to the control unit 60 together with the information of the authentication OK.

  When the control unit 60 receives the authentication OK information, in step S3, the control unit 60 causes the light emitting members 42 and 47 to emit blue light to indicate to the user that the passage is possible, and the side panel 6 and the exit door. 7 is displayed in blue.

  Then, in step S4, the motors 22 of the first slide shutter 10a and the second slide shutter 10b are driven to open the first slide shutter 10a and the second slide shutter 10b, and FIG. The state shown in The opening degree (shutter opening degree) of the first slide shutter 10a and the second slide shutter 10b at this time is adjusted based on the external shape information of the user. For example, information obtained by classifying a user's width size into three levels based on the user's shoulder width and waist width is registered in advance as outer shape information, and it is determined whether the acquired outer shape information is in three levels. The shutter opening is set to a necessary and sufficient opening according to the width size.

  In step S5, it is determined whether the user has passed through the first slide shutter 10a based on whether the first passage sensor 11a has been switched from ON to OFF. When the user enters the gate device 1, the first passage sensor 11a between the first slide shutter 10a and the second slide shutter 10b corresponding to the first slide shutter 10a is turned on, and the user When further proceeding, the first passage sensor 11a is turned off. The controller 60 determines that the user has passed through the first slide shutter 10a due to the switching from ON to OFF.

  When it is determined that the user has passed the first slide shutter 10a, an operation of opening the third slide shutter 10c and closing the first slide shutter 10a is started in step S6. At this time, as shown in FIG. 13 (c), the first to third slide shutters 10a to 10c form a space for partitioning only one user (partition space). It is possible to prevent companion who tries to pass along with the old user. If two people try to enter the partition space, the first slide shutter 10a cannot be normally closed, and thus it is possible to detect illegal intrusion.

  Next, in step S7, it is similarly determined whether or not the user has passed the second slide shutter 10b depending on whether or not the second passage sensor 11b has been switched from ON to OFF. If it is determined that the shutter 10b has been passed, an operation of opening the fourth slide shutter 10d and closing the second slide shutter 10b is started in step S8. At this time, as shown in FIG. 13 (d), the second to fourth slide shutters 10b to 10d are in a state in which a space for dividing only one user (partition space) is maintained.

  Next, in step S9, it is similarly determined whether or not the user has passed the third slide shutter 10c depending on whether or not the third passage sensor 11c has been switched from ON to OFF. If it is determined that the shutter 10c has been passed, the closing operation of the third slide shutter 10c is started in step S10. At this time, the fifth slide shutter 10e is not opened, and the state shown in FIG.

  Thereafter, in step S11, collation is performed by the second authentication means (authentication using the exit-side camera 9) of the face authentication unit 64, and the result is reflected in subsequent gate control.

  The authentication by the second authentication means (authentication using the camera 9 on the exit side) is authentication after the user enters the inside of the gate device 1, and the face information photographed by the camera 9 and the first information The same pre-registration information as the authentication by the authentication means (authentication using the camera 13 of the entrance authentication unit 8) is collated, and the collation result is notified to the control unit 60.

  Then, the control unit 60 matches the collation result of the face information by the second authentication unit with the collation result of the first authentication unit, and both are of the same person registered in advance (second authentication) If it is determined as OK, it is determined that the vehicle can pass as it is, and the processes of steps S12 and S13 are performed. On the other hand, if it is determined that the collation result of the face information by the second authentication means and the collation result by the first authentication means are not of the same person registered in advance (second authentication NG), the passage is impossible. And the processing of steps S14 to S19 is performed. As a result, an illegal intrusion due to so-called “spoofing”, in which another person enters the gate device 1 and passes through as it is immediately after a user who has been properly registered in advance, has been authenticated by the first authentication means. Can be prevented.

  If it is determined in step S11 that the second authentication is OK, in step S12, the control means 60 opens all the fifth to eighth slide shutters 10e to 10h located on the outlet side, and then (f) in FIG. In this state, the user can pass through the fifth to eighth slide shutters 10e to 10h as they are, and can pass through the exit door 7 that has been released from the beginning.

  In step S13, in accordance with the passage of the user, that is, in accordance with the timing at which the fourth to seventh passage detection sensors 11d to 11g and the outlet sensor 51 are sequentially turned from ON to OFF, the fourth to eighth. The slide shutters 10e to 10h are sequentially closed.

  On the other hand, when it is determined in step S11 that the second authentication is NG, that is, when it is determined that the user who has entered the position passing through the third slide shutter 10b cannot pass thereafter, in step S14. In addition, the user is notified of the inability to pass by switching the emission color of the light emitting members 42 and 47 from blue to red. The operating positions of the slide shutters 10a to 10h at this time are the positions shown in FIG.

  In step S15, the control unit 60 drives the motor 61 so as to close the outlet door 7 in preparation for a case where the user attempts to illegally enter the fifth through eighth slide shutters 10e to 10h. In step S16, the first to third slide shutters 10a to 10c located on the rear side are all opened to the state shown in FIG. 14B, and the user is returned to the entrance side. In step S17, as the user returns, that is, in accordance with the timing at which the first to third passage detection sensors 11a to 11c are sequentially turned from ON to OFF, the second to fourth slide shutters 10b. ˜d are closed in order from the exit side.

  In step S18, the first slide shutter 10a is closed a predetermined time after the second slide shutter 10b is closed. In step S19, the exit door 7 is opened, and the standby shown in FIG. Return to the state.

  Thus, after normal passage is completed through steps S12 and S13, or through steps S14 to S19, the user who is determined to be unable to pass is returned to the entrance side, and the operating positions of the slide shutters 10a to 10h and the exit door 7 After entering the standby state, in step S20, the output of the light emitting members 42 and 47 is stopped or switched to the light emission color during standby.

  If the second authentication means is collated with an ID card or a personal identification number, intentional “spoofing” due to the card borrowing or leakage of the personal identification number becomes possible, so the second authentication means is It is best to make biometric authentication without such danger. In this embodiment, since the second authentication means is face authentication using the camera 9, the number of persons existing in the gate device 1 can be grasped. Therefore, even when it is determined that there are two or more persons, it may be determined that the vehicle is not allowed to pass (second authentication NG). As a result, it is possible to more reliably prevent companionship.

  In the gate device 1, the first to fourth slide shutters 10a to 10d are shown in FIG. 13 (a) until the user passes the first slide shutter 10a and passes the third slide shutter 10c. ) To (e), the doors are sequentially opened in accordance with the passage of the user, and the partition space is sequentially moved in the row direction, so that the user can pass without stopping. And the authentication by the second authentication means of the face authentication unit 64 is face authentication using the camera 9 on the exit side, and starts the authentication operation immediately after the user passes through the first slide shutter 10a, A captured image of the user who is passing is acquired from the position away from the user using the camera 9. Therefore, it is not necessary to stop the passing user for authentication, and the second authentication in the gate device 1 can be performed without hindering the user's passage.

(For wheelchair users)
A user using a wheelchair includes information on the outer shape of the wheelchair in the outer shape information by prior registration. When the human sensor 14 detects a user standing in front of the entrance authentication unit 8 in the standby state and determines that the user is a wheelchair user based on a captured image of the camera 13 as shown in FIG. Controls the slide shutter (first to eighth slide shutters 10a to 10h) so as to form a partition space in the gate device 1 in accordance with the outer shape information including the wheelchair.

  For example, as shown in FIG. 15B, the first to sixth slide shutters 10a to 10f are first opened. The wheelchair sensor 50 detects that the wheelchair has entered just before the sixth slide shutter 10f, and the second passage sensor 11b indicates that the back of the wheelchair has passed the second slide shutter 10b. After the detection, the first and second slide shutters 10a and 10b are closed to the state shown in FIG.

  Thereby, a partition space for only wheelchair users is formed in the gate device 1. At this time, it is possible to determine which slide shutter is opened based on the size of the wheelchair included in the acquired outer shape information. When the size of the wheelchair is considered to be substantially constant, a predetermined number of slide shutters are determined. May be opened.

  Then, the second authentication is performed in the state of FIG. 15C, and in the case of the second authentication OK, the seventh and eighth slide shutters 10g and 10h are opened to guide the wheelchair user to the exit. . On the other hand, in the case of the second authentication NG, the first and second slide shutters 10a and 10b are opened and guided to the entrance side.

(Operation change example)
FIG. 16 is a comparative diagram (a) and an operation explanatory diagram (b) for explaining the operation of the first operation modification example of the gate device according to the first embodiment.
In the first embodiment, in order to facilitate the passage of the user, as shown in FIG. 16A, the slide shutter in the traveling direction (the fourth slide shutter 10d in the illustrated state) is slightly advanced. Since the slide shutter that has started to open (the second slide shutter 10b in the state shown in the figure) is closed with a slight delay, the partition space has a shape as shown by hatching in FIG. There is some free space around the user. On the other hand, in the first operation change example, as shown in FIG. 16B, the slide slide that has passed (the second slide shutter 10b in the illustrated state) is completely closed, and then the slide in the traveling direction is performed. The shutter (the fourth slide shutter 10d in the illustrated state) is opened. By doing so, a minimum partition space can be formed as shown in FIG. In this case, smooth traffic is sacrificed to some extent, but it is possible to more reliably prevent companionship.

FIG. 17 is an operation explanatory diagram of a second operation modification example of the gate device according to the first embodiment.
In the first embodiment described above, the size of the partition space is adjusted in the left-right direction by adjusting the opening of the slide shutter according to the lateral shape information such as the shoulder width of the user. It is not designed to adjust to the size. On the other hand, in the second operation modification example, the size of the user in the front-rear direction can be accommodated by adjusting the number of slide shutters that are simultaneously opened.

  For example, as shown in FIG. 17, depending on the size of the user in the front-rear direction, two adjacent slide shutters (in the illustrated state, the third slide shutter 10c and the fourth slide shutter 10d are opened simultaneously, In this way, it is possible to adjust the partition space by using one, two, or three slide shutters that are simultaneously opened according to the size of the user.

FIG. 18 is an operation explanatory diagram of a third operation modification example of the gate device according to the first embodiment.
In the first embodiment, when the user reaches near the center of the gate device 1, the first and second slide shutters 10a and 10b are already closed, and in this state, the second authentication OK and When the determination is made, all the fifth to eighth slide shutters 10e to 10h located on the exit side are opened so that the user can pass directly to the exit side, and then return to the standby state. The next user cannot be accepted until it returns to the standby state. On the other hand, in the third operation modification example, the user arrives near the center of the gate device 1 and accepts the next user in a state where the first and second slide shutters 10a and 10b are already closed. Like that.

  That is, the entrance authentication unit 8 continuously accepts authentication, and first accepts a preceding user. Then, when the preceding user receives the second authentication and becomes OK, the succeeding user is made acceptable. When the subsequent user entrance authentication is completed, as shown in FIG. 18, the first and second slide shutters 10a and 10b are opened to accept the user. As a result, the user is less likely to wait and smooth traffic is possible. In addition, since the subsequent user is accepted after waiting for the second authentication of the preceding user, the preceding user is prevented from returning with the second authentication NG and causing trouble to the subsequent user.

FIG. 19 is a comparative diagram (a) and an operation explanatory diagram (b) for explaining the operation of the fourth operation modification example of the gate device of the first embodiment.
In the first embodiment, the slide shutters are opened and closed symmetrically, and the partition space moves so as to advance straight through the center of the gate device 1. That is, the movement trajectory of the partition space is parallel to the left main body portion 2 and the right main body portion 3 that form the passage side wall, and extends substantially in the center between the left main body portion 2 and the right main body portion 3.

  By the way, in the said 1st Embodiment, although the division space is made into the magnitude | size which only one user who received 1st authentication can pass normally, as shown to (a) of FIG. There may be cases where two users are trying to break in in an extremely close and cramped state. In such a case, it is usually possible to detect illegal intrusion due to the accompanying movement by detecting that the slide shutter is not normally closed or that an abnormal load is applied during the opening / closing operation of the slide shutter. Further, in preparation for the case where it cannot be detected yet, the user's image taken by the exit-side camera 9 which is the second authentication means in the gate device 1 is processed to detect the simultaneous intrusion of two people. It is also possible to make it. However, the camera 9 on the exit side, when the movement trajectory of the partition space is parallel to the left main body 2 and the right main body 3 as in the first embodiment, Users may overlap and may not be able to recognize that they are two people.

  On the other hand, in the fourth operation modification example, each slide shutter is also opened / closed asymmetrically, and the movement trajectory of the partition space is made to the left main body 2 and the right main body 3, that is, to the passage side wall. The trajectory is inclined or passes through a position close to either the left main body 2 or the right main body 3. In this case, for example, as shown in FIG. 19B, two users can be moved in a direction inclined with respect to the left main body portion 2 and the right main body portion 3 so that two users can move. You can shoot without overlapping. Note that FIG. 19B is a diagram in which a passage leading from the entrance to the exit is formed for the sake of explanation, but in actuality, the movement locus in which the closed partition space is refracted between the entrance and the exit. Is to draw. In this example, between the first to third slide shutters 10a to 10c, the movement locus is drawn slightly to the right and parallel to the left main body portion 2 and the right main body portion 3. In this section, the face is viewed from substantially the front. Can shoot. Further, between the fourth slide shutter 10d and the fifth slide shutter 10e, a trajectory inclined with respect to the left main body 2 and the right main body 3 from the right side to the left side in the traveling direction is drawn. Since the user is in a posture in which the side faces the camera 9, the camera 9 can surely photograph two users close to each other.

(Other embodiments)
FIG. 20 is an explanatory diagram of the structure and operation of the gate device according to the second embodiment of the present invention.
The gate device of the first embodiment uses a double sliding slide shutter. On the other hand, as a second embodiment, as shown in FIG. 20, a gate device using a single-open slide shutter group that expands and contracts from the right main body 3 can be used. Also in this case, the same effects as the first embodiment are obtained.

FIG. 21 is an explanatory diagram of the structure and operation of the gate device according to the third embodiment of the present invention.
The gate device according to the first embodiment uses a slide shutter constituted by the opening / closing member 10 as the restricting means. On the other hand, in the third embodiment, as the restricting means, a plurality of elastic members 72 projecting toward the passage side from the left main body portion 2 and the right main body portion 3 respectively are provided in the passage direction and in the vertical direction. Sheets 71 and 72 made of a material such as cloth having elasticity are provided at the front end of the elastic member 72 protruding from the left main body 2 and the front end of the elastic member 72 protruding from the right main body 3. The pair of left and right sheets 70 and 71 are stretched to form the left and right wall surfaces of the passage (gate passage).

  The elastic member 72 may have, for example, the same structure as the opening / closing member 10 of the slide shutter in the first embodiment, or may be a member having another known elastic structure.

  In this case, by adjusting the degree of expansion / contraction of the plurality of elastic members 72 individually, the left and right sheets 70 and 71 can form an uneven wall surface, and a partition space can be formed as shown in FIG.

  Also in this third embodiment, the partition space can be moved toward the outlet side by sequentially expanding and contracting the expansion and contraction member 72. And in this 3rd Embodiment, when a division space moves, the impression that the right and left wall surface of a passage flows smoothly can be given, and the effect of guiding a user to the exit side can be heightened.

FIG. 22 is an explanatory diagram of the structure and operation of the gate device according to the fourth embodiment of the present invention.
In the fourth embodiment, the left main body 2 and the right main body 3 are provided with rails 73 of the orbit, and the base portion 20 of the opening / closing member 10 of each slide shutter can be rotated on the rails 73. is there. In this case, the slide shutter 10 in a state where the partition space is formed moves in the exit direction along the rail 73 while maintaining the state. Therefore, it is not necessary to sequentially open and close the slide shutter in order to move the partition space.

  Further, in the first embodiment, in order to realize smooth movement of the partition space, there is a case where some extra space is generated when the slide shutter is opened and closed. However, in the fourth embodiment, it is formed. Since it is possible to move in the traffic direction while maintaining the partition space, the effect of partitioning only one user can be further enhanced.

  In the fourth embodiment, the opening / closing member 10 of the slide shutter is preferably in a degenerated state when moving from the outlet side to the inlet side. Thereby, an increase in the installation space of the gate device can be suppressed.

  Further, the rail 73 may have a shape that circulates in a vertical plane. In that case, the opening / closing member 10 of the slide shutter is not obstructed by the user by allowing the opening / closing member 10 of the slide shutter to be retracted to the left main body 2 side and the right main body 3 side on the return path from the outlet side to the inlet side. Moreover, the volume of the entire apparatus can be further reduced.

  Various other embodiments of the present invention are possible. For example, in the first embodiment, the outer shape information acquisition unit is configured by the entrance authentication unit 8 that is the first authentication unit, and the entrance authentication unit 8 is installed near the entrance outside the gate device 1. The outer shape information acquisition means only needs to be able to authenticate the user before the user is taken into the partition space, and can be installed at an arbitrary position. For example, the means for performing authentication from a position away from the user using a camera or the like can be installed near the entrance inside the gate device 1, and the camera 9 on the exit side of the second authentication means is In the case where the user can recognize even a user near the entrance, only the camera 9 on the exit side may be used as the outer shape information acquisition means.

  In the first embodiment, the outer shape information is stored in advance in correspondence with the information for authenticating the user. However, when the first authentication means is a camera, the user is photographed. Then, by performing image processing, the user's outline information may be acquired each time. Also, a known sensor other than the camera can be provided to obtain the outer shape information. In this way, in addition to the outline information based on the user's physique, the outline information including the belongings at that time, such as the bag and trunk, can be acquired, and a more accurate partition space can be formed.

  Note that when a camera is used as the first authentication means and there are a plurality of persons in the image-capable area of the camera, it is necessary to cut out only the image of the user who is to be authenticated by image processing. When such image processing is difficult, by providing a booth where only one user can enter in front of the camera, or means for instructing not to receive authentication side by side with two or more people This makes it easy to obtain the external information of the user. The same applies when a known sensor other than the camera is provided as the first authentication means.
