It is a block diagram which shows the whole structure of the gate apparatus which concerns on Embodiment 1 of this invention. It is a top view of the gate apparatus which concerns on Embodiment 2 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.
1 to 3 relate to Embodiment 1 of the present invention. FIG. 1 is a plan view of an elevator hall to which a gate device is applied, FIG. 2 is a plan view of the gate device, and FIG. 3 is a plan view of the gate device. It is a block diagram which shows the whole structure.

  FIG. 1 shows an example in which the gate device according to the present invention is installed at a location leading to an elevator hall. Here, the elevator hall 1 is provided with entrances for a passenger elevator 2 and a passenger elevator 3. The passenger elevator 2 is a normal elevator mainly intended for transporting people. The elevator 3 for personnel cargo is used for transporting cargo in addition to people. Due to such a difference in purpose, the width of the passenger car and the entrance / exit is larger in the passenger cargo elevator 3 than in the passenger elevator 2.

  A gate device is installed at a location leading to the hall 1. This gate device is installed in order to prevent only those who are permitted to enter the hall 1 from passing into the hall 1 and to prevent those who are not permitted to enter the hall 1 from entering the hall 1 for security purposes, for example. . The gate device includes a fixed gate 10 and a movable gate 20.

  One or more fixed gates 10 are provided. Here, two sets of fixed gates 10 are installed at the left and right ends of the passage to the hall 1. One or more movable gates 20 are provided. Here, two movable gates 20 are installed between a set of fixed gates 10.

  The configuration of this gate device will be described with reference to FIG. As described above, here, a total of four gates, that is, a set of two fixed gates 10 and two movable gates 20 are provided. These four gates are arranged in a line on the left and right. Therefore, three gate passages for the user to pass between the gates are formed.

  Each user who goes in and out of the hall 1 through the gate device has an IC card. In each IC card, identification information that can uniquely identify each of a plurality of users is recorded in advance. The IC card is a so-called passive RFID (Radio Frequency IDentification) tag.

  And the reading part is provided in the gate apparatus located in the right side of the passage direction in each gate channel | path. That is, the fixed gate 10 is provided with a fixed gate reading unit 11, and the movable gate 20 is provided with a movable gate reading unit 21. The fixed gate reader 11 and the movable gate reader 21 are for reading identification information recorded on the IC card by wireless communication.

  The fixed gate reading unit 11 and the movable gate reading unit 21 can acquire identification information recorded on the IC card 1 by NFC (Near Field Communication), that is, near-field type non-contact communication.

  In a normal state, the fixed gate reading unit 11 and the movable gate reading unit 21 are in a waiting state for communication with the IC card. Then, when the fixed gate reading unit 11 and the movable gate reading unit 21 are in a communication waiting state, the IC card carried by the user is placed over the fixed gate reading unit 11 or the movable gate reading unit 21 to fix the IC card. When entering the communicable range with the gate reader 11 or the rail 30, the fixed gate reader 11 or the movable gate reader 21 reads the identification information of the IC card using NFC.

  An IC card is an example of an information recording medium that is possessed by a user, in which identification information is recorded, and the identification information is acquired by wireless communication. As such an information recording medium, an active (or semi-active) RFID tag can be used in addition to a passive RFID tag.

  In addition to the fixed gate reading unit 11, an operation unit 12 is also provided in the fixed gates 10 at the left and right ends. The operation unit 12 includes an input device such as a numeric keypad and buttons.

  Each gate device is provided with a flap. The flap is for physically restricting the passage of a person's gate. Each fixed gate 10 is provided with a fixed gate flap 13. Each movable gate 20 is provided with a movable gate flap 23. The gate passage formed between the fixed gate 10 and the movable gate 20 is opened and closed by the fixed gate flap 13 and the movable gate flap 23. A gate passage formed between the two movable gates 20 is opened and closed by two movable gate flaps 23.

  Between the fixed gates 10 at the left and right ends, two rails 30 are installed in parallel. The movable gate 20 is movable by being guided by the rail 30. A position of the movable gate 20 indicated by a solid line in FIG. 2 is a normal position determined in advance between the fixed gates 10. A position indicated by a broken line in FIG. 2 is a predetermined open position. The movable gate 20 is provided so as to be movable between the normal position and the open position.

  The open position is such that the distance between the specific movable gate 20 and the movable gate 20 or the fixed gate 10 adjacent to the specific movable gate 20 is wider than when the movable gate 20 is in the normal position. It is a fixed position. This will be specifically described with reference to the example of FIG.

  When the movable gates 20 are simultaneously in the normal positions, the distance between the gate devices, that is, the width of the gate passage is the distance indicated by A in FIG. When the two movable gates 20 are simultaneously in the open position, the distance between the movable gate 20 and the fixed gate 10 adjacent to the movable gate 20 is extremely short. On the other hand, the distance between the two movable gates 20 extends to the distance indicated by B in FIG.

  That is, in the example of FIG. 2, the open position is a distance between the specific movable gate 20 and the movable gate 20 adjacent to the specific movable gate 20 as compared with the case where the movable gate 20 is in the normal position. Is also set to be wide.

  In the example of FIG. 2, the open position is a position where each of the two movable gates 20 located between the pair of fixed gates 10 is disposed in the immediate vicinity of the fixed gate 10 adjacent to the outside. Is set as However, the setting of the opening position is not limited to this example. In addition, for example, a position where both of the two movable gates 20 are moved toward the one fixed gate 10 may be set as an open position. The open position in this case is determined so that the distance between the specific movable gate 20 and the fixed gate 10 adjacent to the specific movable gate 20 is wider than when the movable gate 20 is in the normal position. It will be a position.

  In the example of FIG. 2, the open position is located inside the fixed gate 10.

  Next, a functional configuration related to the control of the gate device as described above will be described with reference to FIG. In the authentication unit 40, the person who intends to pass through the gate based on the identification information read by the fixed gate reading unit 11 and the movable gate reading unit 21 and the operation content on the operation unit 12 is a normal passer. Or whether it is a passer-by who carries a large object.

  In this authentication, information stored in the storage unit 50 is referred to. In the storage unit 50, information related to the user's authority of the identification information is stored in advance as authentication information in association with the identification information of each user.

  The authority of the user stored as the authentication information is, for example, whether the user is a normal passer or whether the user is a passer who carries a large object. Or a person who is allowed to pass a large object, or the user is not permitted to pass through the gate (a normal person who is allowed to pass through and a person who is permitted to carry a large object) Or any one of them).

  The authentication unit 40 collates the identification information read by the fixed gate reading unit 11 and the movable gate reading unit 21 with the authentication information stored in the storage unit 50, and is input by an operation to the operation unit 12 as necessary. In consideration of the information, the user of the identification information is authenticated.

  For example, in the authentication information stored in the storage unit 50, when the authority of a normal pass-permitter is associated with the identification information read by the fixed gate reading unit 11 and the movable gate reading unit 21, the identification information and As a result of the verification with the authentication information, the authentication unit 40 authenticates that the user of the identification information trying to pass through the gate is a normal passer.

  Further, in the authentication information, when the identification information read by the fixed gate reading unit 11 and the movable gate reading unit 21 is associated with the authority of the authorized person to pass a large object, the verification of the identification information and the authentication information is performed. As a result of this, the authentication unit 40 authenticates that the user of the identification information trying to pass through the gate is a passer who carries a large object.

  In the authentication information, when the authority of any authorized person is not associated with the identification information read by the fixed gate reading unit 11 and the movable gate reading unit 21, as a result of collation between the identification information and the authentication information. Then, the authentication unit 40 determines that the user of the identification information trying to pass through the gate is not a passer. That is, the user is not authenticated as an authorized person (authentication failure).

  Here, in the authentication information, the identification information read by the fixed gate reading unit 11 and the movable gate reading unit 21 is associated with both the authority of a normal permitting person and the permission of the permitting person who carries a large object. In such a case, the authentication unit 40 needs to select whether to authenticate the user of the identification information as a normal passer or as a passer who carries a large object.

  Therefore, in such a case, the authentication unit 40 authenticates the user in consideration of information input by an operation on the operation unit 12. For example, when no operation is performed on the operation unit 12 at the time of reading the identification information, the authentication unit 40 authenticates the user of the identification information as a normal passer. On the other hand, when the button of the operation unit 12 is operated at the time of reading the identification information, the authentication unit 40 authenticates the user of the identification information as a permitted person who carries a large object.

  Further, in the authentication information, even if only the authority of a normal passer is associated with the identification information read by the fixed gate reading unit 11 and the movable gate reading unit 21, the numeric keypad of the operation unit 12 is used. If it can be confirmed that a predetermined password for carrying a large object has been input by the operation of, the authenticating unit 40 authenticates the user of the identification information as a permitted person who carries the large object. You may do it.

  At this time, a password for carrying a large object can be individually set for each user, that is, for each identification information. In this case, authority and a password may be associated with the identification information and stored in the storage unit 50.

  Furthermore, biometric authentication, that is, authentication using information on human physical characteristics can be used. As physical characteristics of a person, for example, a fingerprint, an iris of a pupil, a shape of a palm or a blood vessel of a finger (so-called vein authentication), a human phase, a voiceprint, or the like can be used. Biometric authentication can be used instead of authentication using identification information of an ID tag (IC card), or can be used instead of button input or password input to the operation unit 12.

  That is, authentication by the authentication unit 40 includes, for example, a combination of authentication based on IC card identification information and an operation on the operation unit 12, a combination of authentication based on IC card identification information and biometric authentication, and biometric authentication and operation. Various methods such as a combination with an operation on the unit 12 are conceivable.

  In addition, in the case where only one of the authority of a normal passage permitter and the authority of a pass permission person carrying a large object is set as the authority, the user of the identification information is a normal passage permitter only by the identification information. It is possible to determine whether it is a passer who carries a large object. Therefore, in this case, it is not necessary to provide the operation unit 12. It is sufficient to use at least one of authentication based on identification information of the IC card and biometric authentication. In addition, the authentication part 40 shall authenticate whether the person who is going to pass a gate is a passage permission person who conveys a large sized thing at least.

  Opening and closing operations of the fixed gate flap 13 of the fixed gate 10 and the movable gate flap 23 of the movable gate 20 are controlled by the control unit 60. The fixed gate flap 13 and the movable gate flap 23 are closed in the initial state (normal time).

  When the authentication unit 40 authenticates that the person who intends to pass through the gate is a normal passer, the control unit 60 detects the flap of the gate (the fixed gate flap 13 and / or the movable gate flap 23). ) To allow the passer to pass. At this time, the control unit 60 determines which flap is to be opened based on whether the reading unit corresponding to which gate passage has read the identification information that has been authenticated as a normal passer. To do.

  Specifically, for example, the user of the identification information read by the fixed gate reader 11 or the movable gate reader 21 located on the right side of the gate path between the fixed gate 10 and the movable gate 20 is a normal passer. If it is authenticated, the control unit 60 opens the fixed gate flap 13 and the movable gate flap 23 on the left and right sides of the gate passage. When the user of the identification information read by the movable gate reading unit 21 located on the right side of the gate passage between the two movable gates 20 is authenticated as a normal passer, the control unit 60 Opens the movable gate flaps 23 on the left and right sides of the gate passage.

  In the initial state (normal time), the movable gate 20 is fixed at the normal position between the fixed gates 10 by the fixing means 70. When the authentication unit 40 authenticates that the person who intends to pass through the gate is a permitted person who carries a large object, the fixing means 70 releases the fixing of the movable gate 20. When the fixing means 70 releases the fixing of the movable gate 20, the movable gate 20 can move along the rail 30 from the normal position.

  The moving means 80 moves the movable gate 20 from the normal position to the open position when the person who intends to pass through the gate is authorized to pass a large object. Move along. The moving means 80 can be configured by, for example, a roller provided on the movable gate 20 and rolling on the rail 30 and a motor that drives the roller.

  Either one of the fixing means 70 and the moving means 80 can be omitted. When the fixing means 70 is omitted, the moving means 80 substantially assumes the function of the fixing means 70. When the moving means 80 is omitted, the movable gate 20 which is fixed by the fixing means 70 is moved from the normal position to the open position by a human hand.

  At this time, if the fixed gate flap 13 and the movable gate flap 23 remain open, there may be a problem in moving the movable gate 20 to the open position. In such a case, the control unit 60 opens the fixed gate flap 13 and the movable gate flap 23 so as not to prevent the movable gate 20 from moving to the open position.

  Here, even when the authentication unit 40 authenticates that the person who intends to pass through the gate is a permitted person who carries a large object, the movable gate 20 is fixed by the fixing means 70. Naturally, the movable gate 20 cannot be moved by the moving means 80.

  Therefore, when both the fixing means 70 and the moving means 80 are provided, more accurately, the authentication unit 40 authenticates that the person who intends to pass through the gate is a passer who carries a large object, In addition, after the movable gate 20 is fixed by the fixing means 70, the moving means 80 moves the movable gate 20 along the rail 30 from the normal position to the open position.

  If the authentication unit 40 determines that the user who is going to pass through the gate is not a permitted person, that is, if the authentication fails, the control unit 60 keeps the flaps closed and fixed. The means 70 keeps the movable gate 20 fixed at the normal position.

  The detection unit 90 is for detecting that the movable gate 20 is in the normal position. The detection unit 90 is configured by, for example, a micro switch or a photoelectric sensor. The notification unit 100 notifies that when the state where the detection unit 90 does not detect that the movable gate 20 is in the normal position continues for a predetermined time or more. The notification unit 100 can be configured by, for example, a warning light, a speaker, a display device, or a combination thereof.

  The moving means 80 automatically moves the movable gate 20 to the normal position when a predetermined opening time elapses after the movable gate 20 is moved to the open position, and is in an initial state (normal state). It comes to return to. Therefore, by setting the fixed time according to the opening time, the notification unit 100 can notify when the moving unit 80 cannot return the movable gate 20 to the normal position due to some abnormality. it can.

  In particular, when the movable gate 20 is moved manually without providing the moving means 80, the movable gate 20 is moved to the open position by the notification function of the notification unit 100 based on the detection result of the detection unit 90. Thereafter, it is possible to prevent the movable gate 20 from being forgotten to be returned to the normal position.

  Also, once the movable gate 20 is moved from the normal position and the detection unit 90 no longer detects that the movable gate 20 is in the normal position, the detection unit 90 again places the movable gate 20 in the normal position. When this is detected, it is determined that the movable gate 20 has been returned to the normal position, and the fixing means 70 fixes the movable gate 20 to the normal position.

  In the gate device of this embodiment configured as described above, first, when a normal user who is not carrying a large object tries to enter the hall 1 through the gate device, he / she carries it. Hold the IC card over the fixed gate reader 11 or the movable gate reader 21. If the authentication unit 40 authenticates that the user is a normal passer, the control unit 60 opens the fixed gate flap 13 and / or the movable gate flap 23 to allow the user to pass. To do.

  In this case, the movable gate 20 remains fixed at the normal position by the fixing means 70. Since the user does not carry a large object, the movable gate 20 remains in the normal position and can pass sufficiently even when the width of the gate passage is at the distance indicated by A in FIG. .

  Next, a case where a user carrying a large object tries to enter the hall 1 through the gate device will be described. It is assumed that this large object is of a size that is difficult to pass through the gate device when the movable gate 20 remains in the normal position and the width of the gate passage is the distance A in FIG.

  In such a case, if the user possesses an IC card with identification information associated with the authority of a pass-permitter who carries a large object, this IC card can be used as the fixed gate reader 11 or the movable gate. Hold it over the reading unit 21. And if the said authentication part 40 authenticates that the said user is a passage permission person who conveys a large sized object, fixation of the movable gate 20 by the fixing means 70 will be cancelled | released.

  When the fixing of the movable gate 20 by the fixing means 70 is released, the movable gate 20 can be moved from the normal position to the open position. Therefore, if the moving means 80 is provided, the moving means 80 moves the movable gate 20 from the normal position to the open position. If the moving means 80 is not provided, the movable gate 20 is manually moved from the normal position to the open position.

  In addition, when the user has not only the authority of a pass-permitter who carries a large object but also the authority of a normal passer-permit, the user can move the IC card to the fixed gate reader 11 or the movable gate. While holding it over the gate reading unit 21, the button of the operation unit 12 is operated. By operating the button of the operation unit 12, the authentication unit 40 determines that the user wants to be authenticated as a pass-permitter carrying a large object, not as a normal pass-permitter. can do. In other words, the authentication unit 40 authenticates the user as a pass-permitter carrying a large object after taking into account the content of the operation performed on the operation unit 12 in the read identification information.

  Furthermore, even if the user has only the authority of a normal authorized person, if the password for carrying large items is set, the user reads the IC card with a fixed gate. While holding the unit 11 or the movable gate reading unit 21, the numeric keypad of the operation unit 12 is operated to input a password for carrying a large object. When it is confirmed that the user has the authority of a normal authorized person and the password input to the operation unit 12 is a correct password for carrying a large object, the authentication unit 40 Authenticate the user as a passer carrying a large object.

  In this way, when the user who is going to pass through the gate is authenticated as a permitted person carrying a large object and the movable gate 20 moves to the open position, the width of the gate passage becomes B in FIG. Expands to the indicated distance. In this state, a large object can easily pass through the gate device.

  After the large object passes through the gate device, the movable gate 20 is returned from the open position to the normal position by the moving means 80 or manually. When the detection unit 90 detects that the movable gate 20 has been returned to the normal position, the fixing means 70 fixes the movable gate 20 to the normal position.

  It is desirable that the wiring for supplying power to the movable gate 20 is laid under the floor. And so that the movable gate 20 can be moved, it is preferable that the wiring is provided with a detachable socket at a portion entering the movable gate 20 from under the floor.

  In the above description, the example in which the gate device is provided at a location leading to the elevator hall 1 has been described. However, the installation location of the gate device according to the present invention is not limited to this example. The gate device according to the present invention can be applied to any location where a user carrying a large object may pass. However, the gate device according to the present invention is particularly suitable when both the passenger elevator 2 and the passenger cargo elevator 3 are put into service at the same hall 1 as in this example.

  The gate device configured as described above fixes the movable gate 20 at a predetermined normal position between the fixed gate 10 provided by one or more sets, the movable gate 20 provided by one or more, and the fixed gate 10. The fixing means 70 and the authentication part 40 which authenticates whether the person who is going to pass a gate is a passage permission person who conveys a large sized thing are provided. Then, the fixing means 70 releases the movable gate 20 by releasing the fixation of the movable gate 20 when it is authenticated by the authenticating unit 40 that the person who intends to pass the gate is authorized to pass a large object. It is movable from the normal position.

  For this reason, it is authenticated whether the user carrying a large object has a legitimate passage authority, and when it has the legitimate passage authority, the movable gate 20 should be movable. In this way, the gate passage width can be expanded, and when a user having a proper passage authority is carrying a large object, the gate can be easily passed. In other words, it is possible to handle transportation of large objects while maintaining security.
